Growing old in China in socioeconomic and epidemiological context: systematic review of social care policy for older people
BMC Public Health volume 23, Article number: 1272 (2023)
From 2020 to 2050, China’s population aged ≥65 years old is estimated to more than double from 172 million (12·0%) to 366 million (26·0%). Some 10 million have Alzheimer’s disease and related dementias, to approach 40 million by 2050. Critically, the population is ageing fast while China is still a middle-income country.
Using official and population-level statistics, we summarise China’s demographic and epidemiological trends relevant to ageing and health from 1970 to present, before examining key determinants of China’s improving population health in a socioecological framework. We then explore how China is responding to the care needs of its older population by carrying out a systematic review to answer the question: ‘what are the key policy challenges to China achieving an equitable nationwide long-term care system for older people?’. Databases were screened for records published between 1st June 2020 and 1st June 2022 in Mandarin Chinese or English, reflecting our focus on evidence published since introduction of China’s second long-term care insurance pilot phase in 2020.
Rapid economic development and improved access to education has led to widescale internal migration. Changing fertility policies and household structures also pose considerable challenges to the traditional family care model. To deal with increasing need, China has piloted 49 alternative long-term care insurance systems. Our findings from 42 studies (n = 16 in Mandarin) highlight significant challenges in the provision of quality and quantity of care which suits the preference of users, varying eligibility for long-term care insurance and an inequitable distribution of cost burden. Key recommendations include increasing salaries to attract and retain staff, introduction of mandatory financial contributions from employees and a unified standard of disability with regular assessment. Strengthening support for family caregivers and improving smart old age care capacity can also support preferences to age at home.
China has yet to establish a sustainable funding mechanism, standardised eligibility criteria and a high-quality service delivery system. Its long-term care insurance pilot studies provide useful lessons for other middle-income countries facing similar challenges in terms of meeting the long-term care needs of their rapidly growing older populations.
China’s population of 1·44 billion is ageing fast. People aged ≥65 years old account for 12·0% (173 million) of the population, and this proportion is expected to rise to some 26·1% (366 million) by 2050 (Table 1) . Population ageing is firmly on the national policy agenda but continues to be a major challenge, with both generic and particularly Chinese characteristics. In common with many countries, the rapidly ageing population is a source of fiscal stress and workforce shortfall. More specifically, inequalities in socioeconomic development across China’s vast population and land area make it difficult to support the care needs and wellbeing of all its older people.
Critically for China, its population is ageing while it is still a middle-income country. This dynamic means China faces ‘being old before being rich’ [2, 3]. Gross Domestic Product (GDP) per capita increased from 405 US$ in 1979 to 10,431 US$ in 2020 (Fig. 1A), with a long-run economic boom that peaked in 2007 (13·6% GDP growth per employed person) . China is expected to reach the high income threshold (US$12,700 per capita) in 2025, but will still be years away from expenditure and consumption levels of G7 countries.
Among the G7, Japan introduced universal long-term care insurance (LTCI) in 2000. In contrast to China, Japan ‘grew rich before growing old’. Japan nevertheless struggles to fund the social care it aspires to provide [5, 6]. Japan’s experience highlights the challenge for China to develop a financially sustainable social care system in the context of lower per capita income.
Comparing China to India, both middle-income countries with extensive geography and population, China’s economic growth and population ageing is considerably faster (Table 1). China’s decline in fertility rate has outdone India’s for five decades, approximately equals that of high income countries such as the United Kingdom (UK) and the United States of America (USA), and approached that of Japan in 1995 (Fig. 1B) . Cohorts born in China’s 1950s and 1960s baby boom are reaching retirement age, with replacement by smaller cohorts born in the 1990s . China’s shrinking workforce is occurring at the same time as the need to drive up age-related social care capacity.
Comparison of China with the USA, UK, Japan and India, demonstrates a need to understand the social policy implications of population ageing in both generic and unique aspects of the Chinese context.
We aim to achieve this by summarising China’s key demographic and epidemiological trends relevant to ageing and health from 1970 to present, using official and population-level statistics, and demonstrate how major socioeconomic reforms since 1970 have contributed to China’s improving population health in a socioecological framework . We explore their shaping of social care policy for the older population, and carry out a systematic review which aims to answer the question: ‘what are the key policy challenges to China achieving an equitable nationwide long term care (LTC) system for older people?’.
China’s population health trends
Over the past 50 years, China’s population has grown by >600 million with dramatic shifts in age structure. In 1970, 51·7% of the Chinese population was <20 years old and only 3·7% was >65 years old (Table 1). China and India had a similar old-age dependency ratio (OADR, 0·08, 0·07, respectively), and >50.0% of each country’s population were children or adolescents (0–19 years). By 2020, the proportion of the population <20 years old had fallen to 23·4%, the same level as the UK. China’s OADR was almost twice that in India. Projections estimate China’s >65 year old population to almost double that of India by 2050 and exceed that of the UK and the USA. By 2050, China’s OADR is expected to reach that of the UK, and to approach that of Japan in 2020 (respectively, 0·48 and 0·52).
The working age population is predicted to decline by 23% from 925 million in 2011 to 800 million in 2050 . Exacerbating the problem of population ageing, retirement ages in China are lower than in many other countries.
At the same time, China’s total fertility rate (TFR) of 5·6 in 1970 declined rapidly to levels below the population replacement rate of 2·1 by 1991. Contraction of the size of younger birth cohorts after 1991, individuals currently ≤30 years old, is a key part of China’s demographic shift .
China’s TFR currently stands at an estimated value of 1·3 (12 million births per year), according to the Seventh National Population Census, published in 2021 . The World Bank estimates a higher value of 1·7 (Fig. 1B) . The discrepancy is largely attributed to differences in model estimation, where counting births accurately across all Chinese territory was subject to error . For verification, the Seventh Census used administrative records e.g. citizenship information and big data sources, with a low missing rate (0·05%) . China’s TFR is expected to remain stable for the next three decades . However, skewed sex ratios at birth make TFR prediction difficult . In 2020, the United Nations (UN) reported 113 males per 100 females, with values expected to remain skewed into 2050 .
All-cause mortality, life expectancy and China’s epidemiological transition
China’s population health trends follow the classical demographic transition linked with a country’s economic development. Since 1990, non-communicable diseases (NCDs) have largely replaced communicable diseases, with five risk factors (high fasting plasma glucose, high blood pressure, high body-mass index, smoking and air pollution) becoming dominant .
Improved maternal education, greater access to antenatal care and immunisation have resulted in a substantial reduction in infant and child mortality rates since 1990 (average annual declines of 6·2% and 6·6%, respectively). China achieved Millennium Development Goal 4, a two thirds reduction in under-5-mortality rate, by 2008, seven years before its target date .
Adult mortality (20–64 years) has declined on average 2·3% per year between 1990 and 2019 (Table 2). For older people (≥65 years old) the average annual decline was 1·6%. Life expectancy at age 65 increased from 13·8 to 17·2 years between 1990 and 2019, with increasing female life expectancy advantage .
A global mortality shock, induced by the SARS-CoV-2 (COVID-19) pandemic, has impacted health trends. Since December 2019, the pandemic has resulted in some 15 million excess deaths globally . Inconsistent death registration complicates estimates of COVID-19 deaths. Excess deaths (the difference between observed and expected deaths in a time period) is the most reliable, though not cause-specific, way to manage this issue .
On 6th December 2022, China’s official statistics reported 5,235 COVID-related deaths. Lifting of the zero-COVID policy on 7th December led to an estimated 60,000 excess deaths in the following month . The Global Burden of Disease (GBD) Study estimates that excess deaths will reach 322,000 by April 2023 .
Older people, and those with comorbidities, are particularly vulnerable to severe infection. In China, early stages of the pandemic (April-May 2020), led to a case-fatality ratio of 18·5% among 70–79-year-olds, increasing to 32·1% in those ≥80 years old . Average age of death is 80 years old; 90·1% of fatalities have occurred in those aged ≥65. This follows the age-related pattern of excess deaths observed for other respiratory illnesses such as influenza .
The impact of excess deaths on life expectancy is still unknown. In the Spanish flu pandemic (1918-20), life expectancy declined continuously among all countries with available data but recovered within one-to-two years. Life expectancy losses in 2020 bounced back to pre-COVID-19 levels within a year in some European countries (Sweden, Switzerland and Belgium). Recovery is attributed to public health measures aimed at reducing mortality among those aged ≥60, notably COVID-19 vaccination .
As of November 2022, some 65·8% of Chinese adults ≥80 years old had received a COVID-19 vaccination, and only 40% had received a booster . Vaccine hesitancy is associated with concerns for safety, effectiveness, and lack of knowledge: Chinese adults aged ≥60 are more likely to trust media, relatives and friends for COVID-19 vaccination information . It is plausible that low vaccination rates will stall China’s life expectancy improvements.
Low vaccination uptake also increases older people’s risk to long-lasting, adverse effects of infection. One study in Shandong province (n = 255) showed that more than half of unvaccinated patients experienced post-COVID-19 symptoms and abnormal chest scans one year after hospital discharge . Cognitive impairment was found in 12·5% of COVID-19 survivors ≥60 years old (n = 3233), with no pre-existing conditions, 12 months after infection .
Travel restrictions have reduced viral transmission, however serious public health concerns arise over heightened risks of social isolation and loneliness among older adult populations . High psychological distress (a score of ≥22 on the Kessler Psychological Distress Scale) increased by 7·8% among rural older adults aged ≥60 in Shandong province (n = 2749) between May 2019 and August 2020 . This risk was higher among those who became isolated during the pandemic.
A three-fold increase in ≥65 year old population between 1970 and 2020 (Table 1) has driven a rapid rise in age-related disability. Estimates of the number (%) of older adults (aged ≥60) living with disability range between 33 and 45 million (19–26%) [32, 33].
Functional impairment and disability at older ages may be caused by one or more chronic diseases, including Alzheimer’s disease and related dementias (ADRD), which accounted for about 10% (ADRD estimate: 10·4 million) in China in 2016 . Prevalence of ADRD is highest among those ≥80 years old (12%) . A meta-analysis of Chinese surveys, taking account of methodological and geographical differences, produced a similar estimate (9·5 million) . A model-based prediction put the estimate of ADRD at 16 million in 2020, increasing to 49 million in 2050 . Even if ADRD incidence rates declined by 10% per decade over the coming three decades, the number of cases would approach 40 million by 2050 .
Cardiovascular disease (CVD), and particularly stroke, is the leading cause of disability-adjusted life years (DALYs) in China. In 2018, 290 million were living with CVD (an increase of 60 million from 2007) . According to the GBD Study, prevalence of CVD among ≥80 year olds increased by 5·5% from 1990 to 2019 (47·3% to 52·8%). 28·8 million people are currently living with stroke (ischaemic stroke, 24·1 million) .
Hypertension and diabetes are major risk factors for vascular disease and disability. The China Hypertension Survey (2012-15) found a high prevalence of hypertension in ≥75 year olds (60%) . Prevalence of diabetes is 12.4% among Chinese adults aged ≥18, compared with a global estimate of 8·3%, and ranked highest in the world (89·5 million) [39,40,41,42]. A national survey estimated prevalence of diabetes in 16.5% of adults aged ≥70 .
Based on these disease trends, and the predicted size of the older population, the number with disability (aged ≥60) is set to increase further by 2050 .
The burden of age-related disability is heterogenous across China. Rural China has a higher age- and sex-standardised prevalence of ADRD than urban regions in the age ≥65 population (rural 6·1% vs. urban 4·4%) [44, 45]. Cities attract younger people with higher education levels, for higher wages and standard of living. These indicators are associated with good health, and lower risk of chronic disease . Lower income and education level, both associated with rural residence, are barriers to health care access . Consistent with this pattern, the Chinese Longitudinal Healthy Longevity Survey (CLHLS) observed a higher prevalence of good or very good self-rated health among urban residents aged ≥80 than their rural counterparts in 2018 (50·2% vs. 45·1%) .
Disparities between rural and urban regions are more broadly influenced by China’s geographic diversity and differing levels of socioeconomic development. China has high geographic inequality in health care resources: institutions, health workers and beds . The more developed, southern and eastern provinces generally have better health compared to the mountainous western and northern regions, where resources are sparse .
The mortality rate in the eastern province of Shanghai was half that in the western province of Qinghai in 2018 (391 vs. 796 per 100,000)  Age-standardised years of life lost per 100,000 were dramatically higher in Qinghai than Shanghai (2700 vs. 650 per 100,000) . In 2012, under-5 mortality in Shanghai was lower than the USA and New Zealand. Comparatively, rates were 32 times greater in Sichuan province (western China), exceeding that of Bangladesh, and similar to Burkina Faso .
Estimated prevalence of dementia in the ≥65 year old population is far higher in western China (7·2% vs. 4·8% in southern China) . 38·6% of adults ≥60 years old in the western regions live with depression, compared to 26·6% in the East . Estimated stroke prevalence is nearly 2.5 times higher in northeastern compared to south-eastern areas. Prevalence of CVD is 12·6% in northeast China and 8·0% in the South [55, 56].
Health inequalities by region are further determined by the country’s ethnic and cultural diversity. The 2020 national census estimated that Han Chinese accounted for 91·1% (1286 million) of the population, with the remaining 55 ethnic groups accounting for 8·9% (125 million), the largest being Zhuang, Hui, Manchu and Uygur . Less developed regions are more ethnically diverse. Of China’s 56 ethnic groups, 44 are concentrated in China’s western provinces . Despite improvements, ethnic minority health status continues to lag behind that of the majority Han Chinese population. Self-rated health is poorer among ethnic minority groups . Low socioeconomic status (poverty, low income, low-status employment) and education level are associated with poorer health outcomes .
Although women live longer (Table 2), they tend to report more symptoms and receive more diagnoses than men. In 2015, an estimated prevalence of multimorbidity in older women (aged ≥60) was 57% compared to 46% in older men . As women tend to outlive their husbands, they are more likely to receive poor quality care and have unmet care needs .
Determinants of China’s population health
Social, educational, and economic reforms over the last 50 years have led to dramatic improvements in China’s population health (Fig. 2). Using a socioecological framework (Fig. 3), we examine how key reforms have impacted social determinants of health, and shaped social care policy for the older population .
Wealth and income are each closely associated with improvements in health . Older Chinese people who report excellent or very good health have on average twice the household income of those reporting worse health. A strong inverse association between household income and poor self-rated health was observed in the 2006 Chinese Health and Nutrition Survey, representative of nine provinces and 42% of the population .
Economic growth in China accelerated after introduction of reforms in 1978 . The largely isolated economy grew by some 4·4% per year in purchasing power parity between 1952 and 1979. Introduction of the ‘Open Door Policy’ in 1978 opened China to foreign investment. ‘Special export zones’ for foreign trade were established in Guangdong province and Fujian province. China joined the World Trade Organisation in 2001 . The rural economy was boosted through introduction of the Household Responsibility System in 1979, which decollectivized agriculture in favour of household-based rights to land use and to benefit from sale of agricultural products .
Since 1978, approximately 800 million people have been lifted out of poverty in China . This decline is the result of higher average incomes, not a reduction in inequality. Income inequality, measured by the Gini coefficient, has been growing since the 1978 reforms and is now reported to be higher than in the USA . In 2021, the urban-rural income ratio stood at 2·7 to 1 .
From 1990 to 2013, China contributed to falling rates of extreme poverty (1·90 US$ per day, per person),  making up nearly half of those in poverty globally, to 9·3% . Rural poverty was reduced from 56 million to 17 million people between 2015 and 2018 . The Chinese government allocated 91 billion RMB (13 billion US$, 11 billion GBP) to poverty alleviation funds for 2019  and announced it had eliminated extreme rural poverty in February 2021 .
Changing fertility policies
Expanding population size in the 1960s resulted in introduction of family planning policies and campaigns to alleviate severe poverty and promote economic growth . The ‘Later, Longer, Fewer’ campaign, introduced in 1970, led to a dramatic reduction in TFR from 5·7 at its onset, to 2·7 in 1978 . ‘Later’ referred to the encouragement of later marriage, ‘longer’ to greater intervals between births (at least four years) and ‘fewer’ meant a limit on the number of births permitted, at a maximum of two children for urban families and three for rural families .
Introduction of the one-child policy in 1979, coinciding with the 1978 economic reforms, preceded another downward move in TFR, after some delay (Fig. 1B). The TFR plateau may have resulted from variations in policy implementation and fertility rates across rural and urban areas, regions and ethnicities . Although the one-child policy was the general principle, Han Chinese were expected to abide by the rules, while the fertility of ethnic minorities, most concentrated in western and less developed regions, was relatively unregulated . The one-child policy was enforced and monitored in cities, government institutions and state-run businesses . In contrast, the policy was largely unenforced in subsistence farming areas where there was strong resistance. Rules were relaxed in 1984, allowing rural couples to have a second child if their first born was a girl . By 1991, TFR fell to the population replacement level of 2·1 .
Shrinkage of the working population led to the two-child policy in 2016, which meant some 90 million women became eligible to have a second child . However, the number of births increased only in the first year, and has since declined. A three-child policy was introduced in May 2021 with mixed success: socioeconomic factors, including high costs of child-rearing, difficulty in accessing affordable childcare, along with women’s greater access to higher education and employment, have resulted in few women choosing to have large families .
During the lifetime of China’s present older population, the country has rapidly scaled the Preston Curve in terms of life expectancy (Table 2) . Education is strongly associated with life expectancy, morbidity, health behaviours, labour market potential and health literacy .
Substantial improvements in education attainment resulted from introduction of nine years of compulsory education in 1986. From 1982 to 2010, the percentage of adults with a lower secondary education almost tripled (from 22·8% to 65·3%) . By 2010, China’s secondary education enrolment reached 88·0%, closing the gap with other upper-middle-income countries such as South Africa and Brazil, despite lower GDP per capita .
Poor living conditions, an ageing teacher workforce, and lower education budgets in rural areas, mean education quality lags behind that of cities . Households in the eastern regions have the highest average annual investment in primary and secondary education. Children in lower income households are more likely to drop out or repeat a school year . China’s 14th Five Year Plan (2021-25) aims to narrow the urban-rural gap in access to quality education, including grouping schools under leadership of one outstanding school, and digitalisation of education .
China’s export-orientated economy has generated huge demands for labour in urban regions. To meet this need, the central government relaxed the household registration system (hukou) in 2014, so that migrants could exchange their hukou status from that of origin to destination areas . The hukou system was intended to reduce permanent rural-to-urban migration, protect agricultural production and promote societal equality in the face of rapid urbanisation . It involved compulsory local registration at birth, as a rural or urban citizen, with resultant area-based eligibility for social services including health, education and welfare.
Higher city wages and the changes to the hukou system have promoted large-scale internal migration  (Supplementary Table 1). Between 2010 and 2020, the number of internal migrants more than doubled (154 million to 376 million). Internal migration, defined according to residence outside of region of household registration , is reflected in the decline of the rural population since its 1990 peak, although still >500 million in 2020 (Fig. 4) . China’s agricultural labour force declined rapidly from 1990 to 2019 (from 59·7% to 25·3%) .
This flow of rural populations to urban areas has resulted in significant disparities in regional population age structures and proportion of older people. Origin regions have become depleted of younger people due to migration of the young workforce. At the same time there has been return-migration of the older workforce . The main flow of migration is from western and central China to the East .
It would be over-simplifying to describe internal migration as purely rural-to-urban. Increasingly, there is counterflow migration, when young adults choose to return to their family in rural provinces from the city . Youths cite a better quality of life in the countryside: cities are associated with ‘city disease’ (chengshibing) characterised by high rents, poor air quality and long working days . Expanding internet access, e-commerce and rail links have also helped to increase access to cities, raising income in rural areas. The COVID-19 pandemic crystalised this pattern. In 2020, the total number of migrant workers was 286 million, a decline of five million from 2019 .
Changing family and household structures
The importance of family in China is signalled by the positioning of the surname first, before the given name. Filial piety is at the centre of traditional Chinese culture, where a child is expected to care for their ageing parents . A focus on family-based care for older people remains China’s national policy principle under a 90-7-3 framework, dividing older adults’ care into three groups: 90% are expected to be cared for at home, 7% with support from community-based services, and 3% in an institution, i.e. a care home or nursing home, where needs exceed family and community caregiving capacity .
Prior to economic reforms, the traditional agricultural economy and patriarchal-led society provided conditions for filial piety, where children were dependent on their elders for social connections and employment . China’s welfare housing system gave older employees priority for better and bigger housing and allowed their married children to live with them. A replacement policy also gave retiring adults the opportunity to secure employment for their children in the same workplace .
However, rising incomes and labour mobility have resulted in multi-generational houses becoming rarer and families more dispersed. By 1990, the extended, three-generation household had become unusual, making up less than 20% of households (Fig. 5) . Average household size in 1982 was 4·4 persons, and this declined to 3·1 in 2010 and 2·6 in 2020 . In 2011-12, only one third of those aged ≥60, who did not live with an adult child, had an adult child living in the same neighbourhood .
However, migration and hukou registration make it difficult to interpret the census data. Many individuals are not registered at their current address. ‘Residence-registration inconsistency’ rose by 88.5% between 2010 and 2021 (492.8 million currently live somewhere other than their household registration) .
The association between unhealthy lifestyle behaviours and NCDs is well known . China’s Health-related Quality of Life Survey for Older Adults in 2018 reported a high incidence of health risk behaviours in participants aged ≥60, particularly physical inactivity (63%) and unhealthy diet (46%) [95, 96]. Almost half of Chinese adults (47%) do not meet the World Health Organization’s recommendations for fruit and vegetable consumption, with the highest prevalence amongst those ≥65 years old (57%) . There was a two- and five-fold increase in obesity in men and women respectively between 1993 and 2015 .
While prevalence of smoking, unhealthy diet, unhealthy weight and physical inactivity is highest among those of lower socioeconomic status, alcohol consumption is associated with higher status . Drinking remains a crucial aspect of social bonding and business interactions for men. Men exhibit higher rates of binge drinking and more days drinking per week than women . 31% of female non-drinkers reported that cultural restrictions were the main reason for abstinence from alcohol . Gendered risk behaviours also extend to smoking: male smoking prevalence in 2015 was among the highest in the world, at 52·9%, compared to 2·7% for women .
Ageing social care policy
These determinants, in combination with demographic changes, are shaping social care policy for the older Chinese population. Relatively few children are available to shoulder the burden of care for the rising number of longer-lived parents and grandparents. According to the China Health and Retirement Longitudinal Study (CHARLS), an individual aged 80–84 has an average of four living children, but those aged 60–64 only have 2·8 . This has led to the emergence of the ‘4:2:1 effect’: couples who are responsible for care of one child and four older parents . Unintended consequences include neglect of elders .
To complement traditional family care, residential provision and old age insurance programmes have been scaled up . However, financing of residential care is means tested, with exceptions for some individuals ≥80 years old, with complex needs, or living alone . In most cases, older people pay for formal LTC from savings which depend on children for financial support . Affordability is a challenge for many; the rural population is particularly disadvantaged, lacking pension rights .
In response, revision of the Protection of the Rights and Interests of Elderly People Law in 2013 (originally passed in 1996) mandates adult children to provide support to their ageing parents, constituting regular visits and attention to their spiritual needs . In 2016, Shanghai’s administration announced that children whose care for their parents is considered insufficient may be put on a credit blacklist, denied a bank account, starting a business, or buying a house . Effectiveness of these measures is unknown. Evaluation relies on older adults to report their children. Fulfilling a quota of visits may be insufficient to meet the needs of all older parents.
China’s emerging long-term care system
In the face of China’s increasing need for care of older people, the 13th Five Year Plan (2016–2020) made healthy ageing a priority on the national policy agenda. In line with the Sustainable Development Goals, Healthy China 2030 was implemented in 2016 as a blueprint for promotion of equitable health . A Peking University-Lancet Commission details policy initiatives to promote the health and care of older people .
At the same time, LTCI pilots, with varying structures of funding and service delivery, were established in 15 cities in 2016 with the aim of providing affordable and accessible care to all. An additional 34 cities were added to the pilot scheme in 2020. A comprehensive analysis by Feng et al. in 2020 identified key strengths and limitations of the LTC system: poor system integration, lack of national assessment and eligibility criteria, varying regulation and care quality, increasing private sector growth, and slow development of home and community-based services (HCBS). The authors also identified vast inequalities in LTC needs and service provision between urban and rural areas .
Building on these findings, we undertook a systematic review of evidence since the analysis by Feng et al., and introduction of the second pilot phase, to answer the question: ‘what are the key policy challenges to China achieving an equitable nationwide LTC system for older people?’.
Following PRISMA guidelines , two reviewers independently searched academic databases: PubMed, EconLit, MEDLINE, Social Science Research Network, Wiley Online Library, Google Scholar, Embase, APA PsychInfo and the China Knowledge Resource Integrated Database (CNKI), using search terms “China” and “long-term care” or “geriatric care” or “elderly care” or “integrated care” and “long-term care insurance” or “long-term care system”.
Studies were eligible for inclusion if published in English or Mandarin Chinese between 1st June 2020 and 1st June 2022. Any study design was eligible for inclusion, so as to include policy literature not published in academic journals. One reviewer searched and read studies in English, and the other in Mandarin Chinese. To minimise selection bias, the reviewers and two additional authors read abstracts and agreed the set of included studies. Fig. 6 summarises the search strategy and yield.
When looking at the findings of each study, we considered the possibility of information and selection bias, and quality of the findings, in the context of the overall evidence. Data were extracted by two researchers, independently, to document details of the study characteristics, novel findings, implications and recommendations. Results were validated by two additional authors (see Supplementary Table 2 for summary of systematic literature review search strategy and selection, according to PRISMA guidelines).
42 studies (n = 16 in Mandarin) were included in our systematic review. Table 3 summarises the study characteristics and findings. Four themes emerged: poor quantity and quality of service provision, preferences for family care, inequitable distribution of cost burden, and varying eligibility for LTCI.
Service quality and provision
Service providers recognise the limited scope of LTC services, and low quality, among major difficulties to be addressed as the LTC market expands .
The time-intensive nature of LTC requires a large, skilled workforce . However, care workers are given low social status, with limited policy support, attracting few to the profession [133, 115]. High staff turnover rates since the emergence of COVID-19 have further diminished care quality [119, 137]. Increasing salaries and training opportunities, to retain and attract staff, have been proposed to meet the increasing demand for care [119, 137].
Distribution of LTC resources are skewed towards urban areas, despite an urgent need for services in rural regions, where older people have poorer health and are more likely to live alone [136, 122]. Despite the 90-7-3 LTC policy goal, investment is predominantly in institutional care, neglecting HCBS. Institutional care beds are oversupplied and met with low occupancy rates . Current uptake of HCBS is low (<10% in some areas) . In many pilots, HCBS was the least popular mode of delivery amongst older adults, and had limited capacity to care for those with disabilities [136, 110, 145]. Management fragmentation and multi-leadership of LTC at national and local level contribute to this problem [107, 147]. There is no centralised management of HCBS .
Encouraging nurses to work in both HCBS and institutional settings, and training “integrated care managers” to coordinate care resources, could improve quality and encourage greater use [112, 145, 148]. Government awareness programmes of HCBS could also enhance uptake [118, 121, 149]. Improved governance, through joint-working across regional government departments, could help to understand where resources are most needed [107, 147, 108].
Preferences for care
Within regions, heterogeneity of income, wealth and living conditions mean that LTC systems face expectations arising from a broad range of care needs and preferences for mode of delivery [136, 145]. However, differing needs of older adult groups are not being paid attention to . A ‘person centred care’ approach is required [137, 110].
Preferences shift towards formal care in more economically developed regions and large cities . In Xiamen, those with a higher education level and better economic status were more willing to accept integrated medical and care services . In Shanghai, the number of people receiving formal care increased over two-fold between 2018 to 2019 .
Despite these regional differences, preferences for family care remain widespread across China and are largely dependent on participants’ distance to and number of children [145, 150]. In most cases, those with a greater number of children prefer home-based care [150, 135, 144]. In Suzhou, those with more children were able to afford institutional care . Improving the design and proximity of nursing homes to communities could facilitate the willingness of older people to enter .
In the COVID-19 pandemic, where institutions were forced to postpone entry of new patients, family care was essential [137, 143]. However, many older people who relied on family care were isolated at home, unable to use mobile technology . Poor technological literacy, service standards, privacy fears and unwillingness to pay for smart old age care services contribute to low uptake. Improving older adults’ technological literacy and implementing incentives for providers to deliver affordable, quality care, could facilitate the safe use of smart services and suit preferences to age at home [151, 106, 132, 152]. Strengthening family care policies through regular skills training, piloting a family care allowance, welfare payments and cash subsidies, are also important policy proposals [143, 128, 115].
Eligibility criteria for LTCI vary considerably across pilots, often excluding those with mild and moderate cognitive impairment [112, 110]. Potential service users are often unclear about their service entitlement meaning older adults with the same level of disability are unable to access the same services [110, 138]. Assessment tools are dominated by a single-type indicator .
Adequate information on eligibility should be made available to the public . A unified standard of disability assessment is required, so that the extent to which mild and moderate impairments are insured can be understood by policymakers and the public [129, 112]. Regular reassessment is needed to develop personalised care plans and allocate adequate resources [112, 115]. A big data platform, recording multi-dimensional disability assessments, could facilitate nationwide standardisation .
Qingdao’s pilot reduced ‘social hospitalisation’ by 12% when patients who did not require hospital inpatient services were transferred to institutional or home-based care. Increased LTC service spending was offset by decreased inpatient service spending, with a net cost reduction of >10,000 RMB (1,500 US$, 120 GBP) per person . LTCI significantly reduced utilisation of outpatient and inpatient services according to CHARLS, cutting expenses by 24% and 20% per year, respectively [108, 122, 131]. However, LTCI expenditure is expected to exceed revenue after 2029 in Xiamen .
Cost-efficiency of pilots’ varies due to their reliance on social health insurance (SHI) as a main source of funding, which despite near universal coverage, is based on regional socioeconomic characteristics [115, 110, 138, 126] All pilots cover participants in the Urban Employee Basic Medical Insurance (UEBMI); some have extended cover to urban and rural residents (URRBMI) . Reimbursement rates for UEMBI are fixed at 90%, while rates are 70–80% for URRBMI. As such, poorer families face exclusion from formal LTC because they are unable to meet out-of-pocket charges [114, 135].
Nationally, this hazard is being tackled with government-funded support for providers if their services are made available to low-income users. However, fee-for-service arrangements for paying providers is widespread, incentivising unnecessary care and excessive costs. Providers often reject potential service users if they are deemed to incur high costs.
In response, the second pilot phase announced LTCI independence from SHI . However, most cities continue to rely on surplus health insurance [126, 111]. Greater public health expenses since COVID-19 has further increased pressure on SHI funds, impacting LTCI fundraising . Government subsidies, a unified move towards proportional funding and criteria to guarantee basic benefits, particularly for those with low economic status, could be beneficial [111, 143, 120, 115]. Germany and Japan supplement SHI with mandatory contributions from employed people of working age . China may adopt this approach to reduce reliance on SHI. Mandatory contributions from employers and urban retired employees could also increase revenue of LTCI funds, and improve system fairness . However, implementation may prove difficult as employers are already required to make contributions to other social insurance programmes .
Dramatic improvements in life expectancy, adult and child mortality have resulted in a seismic shift in China’s population from a predominantly young to a rapidly ageing population within a period of 50 years. By 2050, it is projected that China’s ≥65 year old population will exceed that of the UK and the USA, and approach that of Japan.
Using a socioecological framework, we examine reasons for why China’s population health has rapidly improved from 1970 to 2020. Economic and educational reforms have resulted in significant reductions in poverty and greater labour mobility.
However, longer life expectancies come with an increased burden of age-related conditions. Following the country’s economic development, NCDs have largely replaced communicable diseases, influenced by a high prevalence of smoking, alcohol consumption and obesity. An estimated 33 million older adults (aged ≥60) are living with disability, set to increase further by 2050 . The impact of COVID-19 on disability is still unknown. Emerging evidence shows high rates of cognitive impairment and post-viral symptoms among older adults.
Crucially, China is still a middle-income country. High-income countries such as Japan, the USA and the UK are struggling to meet the care needs of their older populations, and China faces the additional challenge of ‘being old before being rich’. Mass internal migration of the younger population, in the context of changing fertility policies, have dispersed families and shaken traditional models of care. A huge number of older people face the possibility of inadequate care. For a population aged ≥65 which is expected to reach 366 million in 2050, the scale of this issue is immense.
In response, national policy has focused on rapidly scaling up provision of equitable and affordable care for all. Since 2016, China has implemented 49 LTCI pilots across a range of cities to find the most suitable LTC model for its older population with varying care needs. The most recent evaluation of these pilots was conducted by Feng et al. in 2020, who highlighted strengths and weaknesses based on the first 15 pilots. An additional 34 cities were added to the pilot scheme in 2020. We undertook a systematic review of Chinese and English evidence, to include findings from the second pilot phase.
A strength shared across pilots is their reliance on funds from a nearly universal SHI, maximising the pool of risk. However, shallow coverage in terms of services and reimbursement rates means high out-of-pocket charges for users. Benefits packages are biased towards urban employees, where more generous packages are applied to participants of UEMBI over URRBMI. Proportional funding and mandatory employment contributions could assist lower socioeconomic groups who are unable to afford care. In Germany, eligibility for LTC requires almost all workers and pensioners to contribute to social insurance . In Japan, contributions are based on earnings, levied on people aged ≥40 . These compulsory schemes have done well to address unmet need among poorer groups .
Narrow eligibility criteria means only a small percentage of the disabled population have access to LTCI. The criteria in most pilot studies exclude mild and moderate cognitive impairments. In contrast, the Japanese system provides support for those ≥65 years old based on need alone, including mild impairments and independent of income and wealth, and LTCI cover includes those aged 40–65 with Parkinson’s disease, ADRD or stroke . Forming a nationwide hierarchical assessment of needs, with links to charging standards, could extend coverage and improve equity of China’s system. Regular and multi-dimensional disability assessment can also ensure allocation of appropriate resources.
Addressing current and future needs requires the sector to become more attractive. Increasing wages for LTC staff in the USA promoted greater recruitment, longer tenure and lower turnover . This approach seems suitable in the Chinese context, where high income is the most important criterion for choosing a job . Investment in LTC training programmes for students and current staff increased the number of LTC workers in Japan by 20% between 2011 and 2015 . The Netherlands has developed coaching programmes for its staff, to promote prevention of burnout, while self-managed teams give nurses more autonomy .
Where family care remains the preferred mode of delivery, greater steps can be made to support family caregivers. Caregiver stress in China is associated with financial costs of providing hands-on care . Cash subsidies and welfare payments, like the Carer’s Allowance in England, can support family caregivers .
Technology could also be an effective solution to relieving workforce pressures. A systematic review found that remote interventions for patients with rheumatic and musculoskeletal disorders improved patient-reported outcomes including quality of life, activity, and disease severity . Smart care particularly satisfies preferences to age at home [162, 163]. Where older adults are at a high risk to serious illness from COVID-19, digital technologies can also provide alternatives to face-to-face contact. However emerging literature has shown poor digital engagement among LTC residents during COVID-19 . Where technological illiteracy and reluctance is high among older adults, greater incentives and educational tools are required.
Despite a high proportion of COVID-19 outbreaks in LTC facilities, limited literature has explored China’s policies to support LTC. National guidelines announced a one-off allowance to LTC providers, for deploying additional workers and reimbursing overtime, to ensure continuity of services . Older people who are unable to access unpaid carers have been promised home-based services or temporary residential care. Future research could benefit from exploring the effectiveness and degree of implementation of these policies.
Strengths and limitations
The findings of this review are from a multitude of study designs and provide evidence from different pilots. A wide range of English and Chinese databases were screened to capture as many records as possible. A large number of records was included (n = 42). However, our analysis depends on the accuracy and completeness of information in the published literature. Reports only relate to the situation at the time of writing and therefore do not fully reflect the ongoing pilot experience.
Population ageing in China is driving an increase in need for social care. More than one quarter of the population will be older by 2050 (≥65 year old population projection 366 million). Rapid economic development and increased access to education has led to widescale internal migration. Geographical fragmentation of families poses considerable challenges to the traditional family care model, at the same time as rapidly increasing age-related disability.
China’s main policy initiative has focused on piloting alternative LTCI systems. This is a rational, quasi-experimental approach to determine how best to meet the care needs of older people in a middle-income country with a substantial proportion of low-income households. China’s pilots can provide useful lessons for other middle-income countries with rapidly ageing populations.
Our systematic review highlights significant challenges in the provision of equitable care which suits the preferences of its users. Inconsistent financing, varying eligibility and reduced service capacity are key challenges. Inequity is a consistent theme across pilots, understandable in the context of considerable geographic and socioeconomic inequalities.
