From: Socioeconomic inequality in the prevalence of noncommunicable diseases in low- and middle-income countries: Results from the World Health Survey

Figure 1

Wealth-related relative inequality in non-communicable diseases among adults of 41 low- and middle-income countries. The relative index of inequality shows wealth-related inequality in prevalence of angina, arthritis, asthma, depression, diabetes and comorbidity, among men and women aged 18 or higher, living in 41 low- and middle-income countries that participated in the 2002–04 World Health Survey. Individuals were cumulatively ranked by descending wealth, and prevalence ratios (RIIs) compared disease prevalence in the poorest to disease prevalence in the richest while taking into consideration all other individuals in the regression. Brackets indicate 95% confidence intervals. Model 1 data are adjusted for country of residence and age; model 2 data are adjusted for country of residence, age, marital status, urban/rural area and education.
