ماضي توفيق الجغبير، سمر لطفي الشريف، مأمون أحمد أهرام

الخلاصة: لقد تم توثيق ارتفاع معدلات التدخين في الأردن، ولذا فإنه من المهم أن نفهم الاتجاهات والعوامل المرتبطة بمحاولات الإقلاع عن التدخين؛ مثل الاستفادة من عيادات الإقلاع عن التدخين ومن الخطوط الساخنة الخاصة بذلك. وقد أجريَت مقابلات مع عينة مؤلفة من 3196 من السكان البالغين ممن تزيد أعمارهم عن 18 عاماً بشأن عادات التدخين لديهم؛ فكان 1032 (32.3 %) منهم مدخنين حاليين، و93 (2.9 %) قد أقلعوا عن التدخين بنجاح (8.7 % من المدخنين في وقت ما سابقاً). وإن نسبة مئوية كبيرة من المدخنين الحاليين (62.8 %) كانوا قد حاولوا الإقلاع عن التدخين ولم ينجحوا. وكان نصفهم تقريباً قد سمعوا بعيادات الإقلاع عن التدخين والخطوط الساخنة الخاصة بذلك، لكن 2.4 % منهم فقط استفادوا منها في وقت ما سابقاً. وبعد أن تم إطلاعهم على هذه الخدمات أقرَّ 53 % من المدخنين الحاليين بأنها كانت من المحتمل أن تفيدهم. وكان 19.9 % فقط من المدخنين الحاليين قد تلقوا في وقت ما سابقاً نصيحة من ممارس في مجال الرعاية الصحية تتعلق بالاتصال بهذه الخدمات. فينبغي لهذه الدراسة أن توجه صناع القرار إلى وضع استراتيجيات ترمي إلى الحد من معدلات التدخين المرتفعة في الأردن.

ABSTRACT Increasing rates of smoking in Jordan have been documented. It is therefore important to understand the trends and factors associated with attempts to quit smoking, such as the utilization of smoking cessation clinics and hotlines. A population sample of 3196 adults aged 18+ years were interviewed about their smoking habits; 1032 (32.3%) were current smokers and 93 (2.9%) had successfully quit smoking (8.7% of ever-smokers). A high percentage of current smokers (62.8%) had tried, unsuccessfully, to quit smoking. Almost half of them had heard of smoking cessation clinics and hotlines, but only 2.4% had ever utilized them. After being informed about these services, 53.0% of current smokers agreed that they were likely to utilize them. Only 19.9% of current smokers had ever received advice from a health-care practitioner about contacting these services. The study should guide decision-makers on strategies to reduce the high smoking rates in Jordan.

Arrêt de la consommation du tabac et recours aux services de sevrage tabagique en Jordanie : enquête en population

RÉSUMÉ L'augmentation des taux de tabagisme en Jordanie est avérée. Il est par conséquent important de comprendre les tendances et les facteurs associés aux tentatives d'arrêt de la consommation de tabac, tels que le recours à des cliniques de sevrage tabagique et aux services d’écoute téléphonique. Un échantillon de population de 3196 adultes âgés de 18 ans et plus a été interrogé sur les habitudes de consommation de tabac ; 1032 (32,3 %) étaient des consommateurs actifs et 93 (2,9 %) avaient réussi à arrêter de fumer (8,7 % d'adultes ayant déjà fumé). Un fort pourcentage de fumeurs actifs (62,8 %) avait essayé, sans succès, d'arrêter. Près de la moitié d'entre eux avait entendu parler des cliniques de sevrage tabagique et des services d'écoute téléphonique, mais seuls 2,4 % les avaient déjà utilisés. Après avoir été informés à propos de ces services, 53,0 % des fumeurs actifs convenaient qu'il était probable qu'ils les utilisent. Seuls 19,9 % des fumeurs actifs avaient déjà reçu des conseils d'un professionnel de santé les incitant à contacter ces services. La présente étude devrait orienter les décisionnaires sur les stratégies visant à réduire les taux élevés de consommation de tabac en Jordanie.

Introduction

Numerous studies have reported a substantial health benefit of quitting smoking. For example, similar mortality rates have been documented between those who quit cigarette smoking and those who have never smoked (1,2). The benefits of quitting reach beyond improvements in individuals’ own health and quality of life; Parrott and Godfrey have shown that there are major reductions in the cost of health care, with consequent savings for the national gross domestic product of countries (3). As a result, a growing number of countries have campaigned to reduce the number of smokers and are reporting higher proportions of ex-smokers than smokers (4). The United States of America (USA), as an example, has successfully reduced the prevalence of cigarette smoking among adults from 42.4% to 19.3% between 1965 and 2010, in part due to an increase in the number of those who have quit smoking (5).

Both older and more recent surveys have indicated a high prevalence of smoking among Jordanians, in particular among males, who have a smoking rate as high as 55% (6–8). This correlates well with the rate of lung cancer in Jordan, which ranks second among all cancers in males (9). In the current study, we utilized data from a national survey of knowledge, attitudes and practices (KAP) towards cancer prevention and care in Jordan based on a sample representing the Jordanian population. Our analyses attempted to offer a deeper understanding of attempts to quit smoking by Jordanians, their knowledge of cessation clinics and hotlines and their previous and potential utilization of these services. The role of health-care providers is critical for advising patients and persuading smokers to quit. We therefore investigated whether smokers had ever been advised by a health-care provider to quit smoking.

It was hoped that the data generated would inform efforts to promote smoking cessation in Jordan.

Methods

Study design

This was a quantitative, cross-sectional, descriptive survey. Data collection spanned 2 months from 24 January to 19 March 2011. The survey consisted of 10 sections starting with a section about demographic characteristics. One section enquired about the lifestyle of participants including smoking habits and quitting patterns among smokers as well as their knowledge, attitude and practice towards smoking cessation clinics and hotlines, which was the focus of this study.

Participants

The KAP survey sample was based on the 2004 Jordan Population and Housing Census as the sampling frame. The sampling frame was stratified by governorate, major cities (each city with a population of more than 100 000 was considered a stratum, i.e. 6 cities) and other urban and other rural areas. A 3-stage sampling procedure was employed. First, blocks were selected systematically as primary sampling units (PSUs) with a probability proportional to the size of the PSU. In the second stage, a fixed number of 15 households were selected as final sampling units in each PSU, resulting in a sample size of about 4500 households. In the third stage, random selection of individual interviewees from each household was carried out using Kish tables (10). The final sample size in the KAP survey was 3196 participants (a response rate of 93%): 1647 males and 1549 females. The demographic distribution of the whole interviewed sample are shown in our earlier paper (8). The number of current smokers on which this report is based was 1032.

Instrument

A structured questionnaire was designed by a national advisory committee that consisted of research experts from different research, clinical and academic institutions in Jordan. The design of the survey was based on international references/tools that were used as a guide to the development of the questionnaire and to ensure appropriate themes and adaptation to the local context. Face-to-face interviews were conducted in interviewees’ households and took an average of 30 minutes to complete. Verbal informed consent was obtained; agreement to host interviews in the participants’ house is a culturally appropriate method to obtain consent in Jordan.

A pilot study was conducted to test the survey tool, sampling technique, survey methods and interviewers’ level of work. The pilot study spanned a day and was carried out in one area in the capital city, Amman. The pilot sample consisted of 56 randomly selected subjects.

Following the pilot, a 2-day review session was conducted and resulted in implementation of minor modifications.

Measures

Respondents were first asked if they considered themselves as non-smokers, current smokers or ex-smokers. Those who described themselves as smokers were then asked whether they had tried to quit smoking or not, whether they had heard about smoking cessation

clinics and whether they had ever utilized them. After the smokers had been informed about the availability of smoking cessation clinics they were asked about the possibility of their consulting

one in the future. The latter were measured on a 4-point Likert scale, with scores ranging from very likely to very unlikely. Then they were asked whether any physician or health-care provider had ever suggested these services to them in the previous 12 months to help them to quit smoking.

Data collection

Data collection was carried out in the 3 regions of Jordan (North, Middle and South). The face-to-face interviews were conducted by 18 trained teams. Each team consisted of 3 data collectors, 1 controller, 1 field supervisor and 1 driver. The controllers and supervisors conducted spot checks by randomly visiting some sampled households. In order to facilitate data collection, each interviewing team was assigned a number of blocks in the sample area. Interviewers made repeated attempts to obtain the responses of eligible respondents by calling back to interview respondents who were not home at the time of the first visit or by attempting to persuade respondents who were reluctant to be interviewed.

Data processing and analysis Data entry using Oracle software started 1 week after the initiation of data collection. After editing and cleaning, the data were exported to SPSS, version 17.0. SPSS was used to run univariate and bivariate analyses to describe all the survey variables. As most of the variables in the study were measured on a nominal and/or ordinal level, descriptive statistics were used to describe the basic features of the data. Responses to questions were analysed using the chi-squared and/or Pearson correlation coefficients when comparing sociodemographic groups or ranked data respectively.

Results

Of the 3196 participants interviewed about their smoking habits in the main KAP survey 2071 (64.8%) reported that they had never smoked, 1032 (32.3%) were current smokers and only 93 (2.9%) were ex-smokers. The ex-smokers therefore represented 8.7% of ever-smokers.

Demographic characteristics

The demographic characteristics of the 1032 current smokers are shown on Table 1. Current smokers were mainly males (87.6%) and the majority were young and middle-aged adults (28.6%, 32.6% and 24.2% respectively). Individuals with intermediate education (58.5%) constituted the majority of current smokers compared with those with lower (16.2%) and higher (25.4%) educational levels. Current smokers were also mainly within the low (48.5%) and intermediate (37.8%) income groups rather than the higher income group (13.1%).

Attempts to quit smoking

Self-reported current smokers were asked if they had ever attempted to quit smoking. A considerable proportion of them (62.8%) had attempted to quit but had failed to do so. This compares with 384 individuals (37.2%) who had never tried to quit. There were no significant associations between attempting to quit smoking and sex, age or income. However, a significantly higher proportion of those with intermediate educational level had never tried to quit smoking (41.6%) in contrast to those with lower (31.7%) and higher (30.9%) educational status (P = 0.003) (Table 2).

Potential utilization of smoking cessation clinics and hotlines

Current smokers were asked about their knowledge of smoking cessation clinics or hotlines before this survey. Approximately half of them (50.6%) had never heard of such services. Males (50.6%) had significantly better knowledge of smoking cessation clinics or hotlines than did females (41.4%) (P = 0.044) (Table 3). As for age, although there was no significant difference among the age groups (P = 0.065), a significant trend towards increasing knowledge with increasing age (r = 0.09; P = 0.006) was found. In addition, there was a significant association of knowledge with better levels of education (P < 0.001) and income (P < 0.001). Only 25 current smokers (2.4%) had ever called a smoking cessation clinic or hotline, with no significant associations by sex, education, age or income (Table 3). Interestingly, a significant association was found between attempting to quit smoking and knowledge of smoking cessation clinics or hotlines (χ2 = 7.035; P = 0.005), but not the actual practice of utilizing them (χ2 = 3.268; P = 0.051) (detailed data not shown). In addition, the practice of calling a smoking cessation clinic or hotline did not show any trend with age (r = 0.001; P = 0.980), education (r = 0.03; P = 0.392) or income (r = –0.007; P = 0.815).

After informing them about the existence of smoking cessation clinics and hotlines, we assessed the intention of smokers to utilize these services in the future; 53.0% of current smokers agreed that they were likely or very likely to do so. There was no significant difference by sex in intention to use services (P = 0.499). However, younger individuals were more likely than older smokers to agree that they would seek help from a cessation clinic (P < 0.001) (Table 4). A significant trend was also observed between decreasing age and the likelihood of calling a cessation clinic (r = 0.13; P < 0.001). Significant differences across the 3 income groups were noted, whereby the likelihood of calling a smoking cessation clinic was lowest at the highest income (43.0%) in comparison with 52.8% and 56.4% for the low- and middle-income levels, respectively (P < 0.001). Despite the lack of a significant trend between increasing education and the likelihood to call these services (P = 0.076), individuals with the highest educational level (43.1%) were significantly less likely to utilize such services than those in the low (53.9%) and intermediate (56.9%) educational levels (P = 0.011).

A correlation was found between attempting to quit smoking and the likelihood of calling a smoking cessation clinic or hotline (r = –0.207; P < 0.001) (Table 4).

Role of health-care providers

We asked current smokers whether they had ever been advised by a health-care provider to quit smoking by calling a cessation clinic or hotline. Only 19.9% of current smokers had ever received any advice to quit smoking (Table 5). There were significant disparities in receiving advice from health-care providers among individuals according to income, educational level and age. More specifically, individuals in the higher income and education categories were more likely to be advised by their physicians to quit smoking than were individuals with lower income and educational level (P = 0.003 and P < 0.001 respectively). As for age, younger individuals were less likely to receive advice from their physicians (P < 0.001).

Discussion

We found a high number of current smokers in our survey who had attempted to quit smoking but had failed. Although knowledge of smoking cessation clinics and hotlines existed among half of respondents, it did not translate into action, as less than 3% had ever utilized them. However, the potential use of these services was indicated by around half of respondents. Furthermore, the role of health-care providers in advising smokers to utilize smoking cessation clinics or hotlines was not only minimal but was also biased towards certain subsets of the population.

The quit rate in the Jordanian population on which this study was based (2.9% of the total sample were ex-smokers) was close to the estimated figures in Britain of 1–2% in the last 40 years and 2–3% in 2005 (11), but lower those in the USA, which had a success rate of 6.2% in 2009 (12). However, more of the current smokers (62.8%) interviewed in Jordan had attempted to quit smoking than those in the USA, where 52.4% of smokers had made a quit attempt in 2009 (12). Overall, numerous

different factors are likely to play important roles in quitting tobacco. Health concerns were reported to be a common motivational factor to quit smoking in different studies including those in Saudi Arabia and Lebanon (13–15). Another study illustrated the importance of setting a model for children as the primary reason for quitting smoking, rather than the cost or family pressure (13). It would therefore be interesting to investigate further the reasons for attempts to quit smoking or the lack of such attempts. Initially, it seems that cost was unlikely to be a motivational factor to quit smoking among Jordanians, as income level was not associated with attempting to quit smoking.

However, this observation could be due to the low price of cigarettes not only in Jordan but also in other countries in the Eastern Mediterranean Region (16). We agree with the suggestions of Abdullah and Husten that increasing the cost of cigarette smoking in developing countries by increasing taxes would have an impact on reducing smoking and increasing the readiness to quit (17). It is worth mentioning that an important barrier to utilizing smoking cessation intervention is the higher cost of tobacco quitting services compared with the price of cigarettes (16). The role of education seems perplexing, as those with intermediate education in our study were less likely to attempt to quit smoking. In a study in the USA, attempting to quit smoking was associated with a higher level of education (12). We also found no significant difference according to sex. This is contrary to what has been shown earlier that females are less likely to quit smoking than males due to higher behavioural dependence (18).

Importantly, we found strong correlations of between attempts to quit and knowledge about smoking cessation clinics/hotlines and the probability of seeking help. . In addition, the likelihood of utilizing these services was higher among those who had made unsuccessful attempts to quit smoking. The importance of such services is illustrated by a study conducted among Jordanian university students, who reported that lack of knowledge on how to quit was a reason for not quitting smoking (19). Two studies, one from the USA and another from Hong Kong, found positive results from smoking cessation support (20,21). Similarly, a multinational cohort study found that lack of assistance to quit was predictive of relapses (22). The success rate of smoking cessation clinics has been variable (23). It is likely that the modest success of these clinics is due to their low recognition by the public. This is exactly the trend we found, whereby more than half of our survey respondents had not heard about these facilities and only 2.4% of smokers had ever utilized them. A reason for lack of knowledge could be the existence of only 2 such clinics in the capital, Amman, one of which is government-run and lacks sufficient funding. One solution is to strengthen, integrate and/or increase public knowledge of these services. Other solutions include the integration of counselling into clinical practice including follow-up and medications, as suggested previously (17,24). In addition, the provision of multiple forms of smoking cessation assistance is needed (25).

Previous studies have highlighted the role of health-care providers in attempts to quit smoking. Recent studies revealed that the role of physicians is vital when it comes to smoking cessation (26,27). According to a Centers for Disease Control report, over 50% of smokers received advice from their health-care provider to quit smoking (28). In a sample of mostly long-term cancer survivors drawn from the 2000 National Health Interview Survey, 42.3% of individuals who visited a health-care provider in the previous year reported being asked about their smoking status (29). In addition, two-thirds of individuals smoking at the time of diagnosis reported being advised to quit smoking by a health-care provider (30). Unfortunately, in our study, only one-fifth of smokers who had visited any health-care providers had been advised to call a smoking cessation clinic or hotline. It is also unfortunate that younger individuals were less likely to be targeted for advice by health-care providers as this group were more likely to report that they would seek assistance from smoking cessation clinics or hotlines. In a recently published study, 46.7% of Jordanian physicians were current smokers (31) and, based on a previous study, a high percentage (81%) of them smoked in front of their patients (32). Shishani et al. found that Jordanian physicians and nurses lacked knowledge about the addictive effects of smoking (33). Collectively, these data suggest a limited involvement of physicians in advising patients to quit smoking in Jordan. It is interesting to note that Jordanian (33) and Egyptian (34) health-care providers requested education and training to increase their knowledge and counselling capabilities in smoking cessation. Previous studies conducted in Saudi Arabia and Jordan found that health education is an effective means of smoking cessation (15,19). This enforces the need to establish educational programmes to promote smoking cessation efforts.

It is important to note that, consistent with other self-report interview methods, individuals may be reluctant to state their views objectively and may provide biased answers that are socially acceptable. However, a major strength of our study was the involvement of a representative sample of the Jordanian population.

Conclusion and Recommendations

There was a large difference in our study between the proportion of current smokers who wished to quit smoking and those who had successfully quit. It is also important to highlight the missed opportunities for health-care providers to advise smokers to quit. Concerted efforts need to be initiated among the various social and health groups in Jordan, along with government policies to increase knowledge about smoking cessation services among the public and health-care providers and to support smoking cessation programmes. Income was not associated with desire to quit smoking, which suggests that an increase in the price of tobacco products is warranted.
