Patterns of motivations and ways of quitting smoking among Polish smokers: A questionnaire study

Before Communism collapsed, Poland had the highest level of tobacco consumption in the world, which resulted in an extreme level of tobacco-related diseases [1]. The democratic transformation and national health campaigns, which have begun in Poland in the early 1990s, influenced positive changes in the lifestyle of Polish society. In consequence, morbidity and mortality from tobacco declined although they still remain among the highest in the world, especially from lung cancer [2, 3]. This was directly related to a gradual and steady decrease in tobacco consumption [2, 4, 5]. In the general population of adult men, the rate of daily smokers decreased from 52% in 1990 to 39% in 2000, and in women from 26% to 24%, respectively, however, in the years 2002–2005 this trend has not been such pronounced, with 38% smokers among men and 25.6% among women [6]. Simultaneously, the rate of ex-smokers in the years 1990–1993 increased after one decade from 14% to 20% [5, 7]. It is estimated that only one anti-smoking campaign, "Let's Quit Smoking Together", conducted every year since 1991 on the annual "No Smoking Day" in November, resulted in approximately 2.5 million people quitting smoking in the years 1991–2003 [unpublished data of the Cancer Epidemiology and Prevention Division, Cancer Center and Institute of Oncology, Warszawa, Poland]. A survey conducted for the Cancer Commission of the EU demonstrated that, in 1998, Poland had the most developed anti-smoking attitude among European countries, with willingness to quit declared by approximately 70% of smokers [8]. However, for most smokers, giving up the habit is a difficult process. The majority of smokers try to quit repeatedly, cycling through multiple periods of relapse and remission [9]. Therefore, apart from preventive actions aimed at reducing the uptake of smoking, tobacco-control efforts should focus on giving smokers professional help to quit. Unfortunately, access to professional treatment of tobacco dependence is rather limited in Poland. Despite the continuing high prevalence of smoking, there is a lack of outpatient clinics offering support for smoking cessation [10]. Another problem is the insufficient involvement of Polish physicians in the treatment of tobacco-dependent patients. To date, too great a proportion of them have no adequate knowledge on smoking cessation methods and are poorly skilled in treating smokers. In consequence, physicians try to avoid any professional action, concentrating on minimal intervention and, sporadically, supporting their patients with emotional encouragement to quit smoking [10]. This disadvantageous situation has begun to change in the past several years. Poland, following other countries [11], adopted evidence-based guidelines for the treatment of tobacco dependence [10] which underline the role of individual health professionals, as well as the role of the whole healthcare system in treating tobacco dependence. Moreover, medical practitioners have nowadays many occasions to attend post-graduate courses and training sessions on professional assistance in quitting smoking.

It appears of great importance to recognize smokers' motivation to quit. The answer to the question: "What motivates smokers to quit?" might be a useful tool in tailoring a smoking cessation strategy, both for individual patients and the general population. A growing body of literature indicates that motives to quit could be divided into health, social and financial concerns, and health concern is the most important reason to quit, followed by social considerations [12]. In addition, health concern seems to be the strongest motivator to quit regardless of age, both in adolescent and elderly smokers [13, 14]. In some studies, the most common reason to stop smoking was concern about future health [15, 16], in others it was the occurrence of illness [17, 18].

In the face of an increasing willingness to stop smoking in the entire population of Polish smokers, the purpose of our study was to investigate how Poles, including the medically ill, cope with quitting smoking and what their motivations are.

The convenience sample was selected from the consecutive outpatients attending the Department of Family Medicine, Nicolaus Copernicus University of Torun, Collegium Medicum in Bydgoszcz (NCUT-CMB) because of a variety of health problems, patients of two pneumonology departments (Department of Pneumonology of the Medical University of Gdansk and the Department of Pneumonology and Tuberculosis of the Pomeranian Center for Infectious Diseases and Tuberculosis in Gdansk) treated because of respiratory system diseases, including tobacco-related ones, and patients of an allergology department (Department of Allergology of the Medical University of Gdansk), who in the vast majority were subjects in good condition, undergoing immunotherapy because of Hymenoptera venom allergy. All four departments were screening patients for past smoking and current smoking with a history of quitting attempts during routine visits.

The level of education was recorded as primary, vocational, high and university. Marital status was classified into two categories: unmarried (including widowed or divorced) and married. Self-reported standard of living was used as a proxy for income and was recorded as low, intermediate, high and excellent. Participants were classified by their current occupational status into three categories: 1. blue-collar workers; 2. white-collar workers; 3. others. The latter group included unemployed respondents, including students, never-working housewives and people who retired early due to their health problems.

Approval was obtained from the institutional research ethics committees at the Medical University of Gdansk and the Nicolaus Copernicus University of Torun.

Firstly, some limitations of the study should be pointed out. The study sample was not representative of the whole Polish population, because respondents were non randomly recruited from patients of several health units. In this group, the rate of subjects prompted to quit smoking because of personal health problems, including tobacco-related symptoms, could be higher than in the whole population, mainly among patients of the Department of Family Medicine and two pneumonology departments. On the other hand, among patients of the Allergology Department, only a small proportion of subjects were admitted because of diseases related to or aggravated by tobacco, such as COPD, lung cancer or asthma, which could influence their decision to quit smoking. Furthermore, interpretation of answers to the questions related to events from the past requires some caution [12]. Respondents could have difficulty in recalling precisely some facts, for instance what exactly motivated their quitting attempts, or how many attempts they had undertaken. Finally, the reasons for quitting smoking listed in the questionnaires might not cover all possible reasons to quit, and some subjects motivated to quit by factors other than those listed might not include them in the open answer.

Since there is no representative data on ways of quitting and reasons to stop smoking in Poland, the present study, despite its potential limitations, is the only available estimate of the use of cessation aids. Additionally, these data highlight some motives of smokers that were important for taking the decision to quit smoking. A great part of former smokers repeatedly cycled from smoking to not smoking periods before the final success. These findings are consistent with the statement that quitting appears to be a dynamic process rather than a single event [19]. Polish smokers, as was previously reported [7], attain success in quitting on average at the seventh quitting attempt. In the present study, the majority of former smokers (63%) needed 2–10 quitting attempts to attain success in quitting.

The survey showed that "willpower" and the cold turkey method were the most common approaches to quitting in the study population, which is similar to the situation reported in other countries [9, 20–22]. One explanation for such high prevalence of self-quitting might be that smokers do not perceive smoking cessation assistance as effective [23]. On the other hand, some studies have shown that the long-term success rate is about 5%, when smokers try to quit on their own [9]. Professional assistance increased the success rate to 33% [24]. That may explain why smokers make numerous quitting attempts before they succeed. Another reason for such a high rate of unaided quitting in Poland might be the relatively high cost of nicotine replacement therapy, bupropion or varenicline. This seems to be an important barrier to use of these drugs even if patients believe in their efficacy. It is also likely that in Poland most clinicians underperform in helping smokers to quit for multiple reasons, including lack of sufficient knowledge on tobacco dependence treatment, time constraints, lack of financial incentives, the conviction that most smokers are unable to quit or smoking by clinicians themselves. Nevertheless, current smokers were more frequently engaged in multiple strategies to assist smoking cessation than former smokers, with nicotine replacement therapy mostly preferred. This trend indicates that nowadays in Poland, despite all the imperfections of the health care system as regards smoking cessation treatment, smokers have more possibilities to support their quitting with some formal aid and probably are more aware of the effectiveness of the available smoking cessation methods. Similarly, studies conducted in the American population showed that current smokers believed that nicotine replacement would help in a successful cessation attempt, while former smokers did not believe the efficacy of these products. [25]. As regards alternative methods of smoking cessation, not recommended by the evidence-based clinical practice guidelines [10], our study demonstrated that, in the face of the predominance of the self-quitting method, they are rather not popular among Polish smokers. However, some proportion of them use alternative methods of smoking cessation, with bioresonance as the most common.

Data from a recent review of over thirty retrospective studies on motivation to quit smoking [12] indicate that health is the most important reason for quitting smoking. The results of our study, in medically ill patients however, were consistent with these findings. Taking together all four health-related factors from the list provided in the questionnaire (personal health problems, general health concern, illness of family member and physician's advice) into one general category, health appeared to be the most common motivator to stop smoking. Among health-related reasons, general concern about health relating primarily to future health (awareness of tobacco-related hazard, desire to maintain current health) was the most frequently cited reason for quitting (57%), followed by current health problems (32%), which is consistent with the results of another recent study, in which those reasons were reported on average by 53% and 42% of subjects, respectively [12].

Our survey on motivation to quit demonstrated that many smokers are not successful in quitting before the occurrence of a real health problem. This is consistent with the findings of Eiser et al. [26], who indicated that health concern is a better predictor of quitting interest and attempts than of successful quitting. McCaul et al. [12], on the basis of reviewed reports on motivation to quit from the past five decades, suggested that health concern is a major reason for quitting attempts, but thereafter smokers may notice little in terms of health benefits, which is conducive to relapse. Most of them do not experience serious diseases due to tobacco smoking, such as cancer or chronic obstructive pulmonary disease. Thus, the lack of consideration by quitters of the distant benefits of smoking cessation might be an important cause of relapse.

The contribution of real health disorders to the decision to quit smoking was demonstrated recently in the study conducted within the National Program of Early Detection and Prevention of COPD, which was realized in Poland in the years 2000–2002 [27]. The large scale voluntary spirometry screening of the Polish population with high risk for COPD detected 23% of subjects with airflow limitation. The survey on smoking cessation in current smokers among the screened population conducted a year from spirometry testing and the physician's advice to stop smoking if necessary, demonstrated a significantly greater cessation rate in subjects with airway obstruction compared to subjects with normal spirometric parameters [28]. In the present study, 33% of former smokers who had quit smoking at the first attempt were heavy smokers for no longer than 20 years, and over one third of them were prompted to quit smoking by a serious personal health problem, mostly a tobacco-related one. In this group, the vast majority of subjects were able to quit smoking abruptly and without any aid.

Following health concern and social reasons, which included concern about family members' health, somebody else's instigation and a family member's illness, the expenses on cigarettes was the least common motive for stopping smoking. It is noteworthy that even economically disadvantaged smokers infrequently reported financial reasons for quitting smoking. This paradox may confirm the relation between poverty and tobacco smoking [29], and that many smokers continue smoking even in spite of smoking-induced deprivation [5, 30].

The results of our study on motivation to quit smoking might indirectly reflect attitudes to smoking in the Polish population and the positive changes in these attitudes occurring from the middle of the 1990s. We found that every fifth current smoker reported the cost of cigarettes as a reason for quitting, probably because of the considerable growth of prices of cigarettes in the past several years. However, paradoxically, smokers with a lower standard of living were not more frequently driven to quit smoking by financial concern than smokers with a higher standard. Moreover, smokers with a lower level of education and blue-collar workers were less frequently motivated by social pressure (i.e. somebody else's instigation) than better-educated subjects and white-collar workers. This indicates that people with a lower socio-economic status might be less susceptible to the ongoing positive changes in the lifestyle of Polish society and social pressure not to smoke. We also found that smokers with a lower socio-economic status were more likely to report personal illness as a reason for quitting in comparison to subjects with a higher status. This might indirectly reflect the overall higher morbidity in this population resulting in turn from the higher prevalence of smoking among people with a lower socio-economic status [5].

In addition, the study demonstrated that respondents did not have sufficient knowledge about the harmful effects of smoking and some of them poorly understood the relation between symptoms and smoking. As was previously demonstrated in the U.S., in spite of the widespread general awareness of people that smoking can lead to adverse health consequences, they did not have even a basic understanding of the nature and severity of these consequences and many smokers failed to internalize them [31]. From a public health perspective, therefore, we face an important challenge to increase smokers' awareness of the harm caused by tobacco.

The data from a number of studies on smoking cessation demonstrated that most relapses occur early in the quitting process [32, 33]. However, some relapses occur months or even years after the quitting date [34–36]. In the present study, respondents most frequently relapsed after a month up to a year of abstinence. However, nearly every fifth smoker relapsed after an abstinence of longer than a year. Moreover, the survey on self-reported self-efficacy demonstrated that 3% of long-term abstainers expected a relapse. It was previously demonstrated that abstainers who reported decreased confidence after cessation concerning their ability to maintain abstinence were more likely to relapse thereafter [37]. Thus, we also face a need for screening the population of former smokers who are not convinced about their self-efficacy to sustain abstinence and who may resume smoking after long-term abstinence. Thus, it is necessary not only to ask patients if they smoke and to encourage them to quit smoking but also to ask former smokers whether they are able to sustain abstinence. Those who are doubtful about their self-efficacy to remain abstinent need a profound analysis of their motivation for not smoking and the self-reported potential risk factors for relapse.

The results of the present study may provide important guidelines for developing interventions addressed to current smokers as well as to former smokers at risk of relapse. Firstly, we found that the majority of smokers, including patients with tobacco-related diseases, attempted to quit without professional assistance. Secondly, smokers were driven to quitting attempts mainly by health-related reasons, including the occurrence of health problems. Thirdly, some smokers were not aware of the relation between their illness and tobacco smoking. Finally, a small proportion of long-term abstainers from cigarettes were not confident about their self-efficacy to sustain permanent abstinence, hence still being at risk of relapse. Therefore, we conclude that current smokers should be more strongly motivated by a physician to quit smoking before the occurrence of real illness, better informed about the many health hazards of tobacco smoking, and offered of professional help in quitting. Former smokers should be given more attention and periodic inquiries regarding the smoking habit are worthwhile. Clinicians should better understand the relapsing nature of tobacco dependence and the requirement for ongoing care.
