Clustering of risk factors in the smoking habits of schoolchildren in Sousse, Tunisia

Background: In Tunisia, little is known about the association between tobacco use and other chronic disease risk factors. This is the case for both adults and children. It is important to know the characteristics of young smokers to facilitate the creation and implementation of future programs for tobacco prevention. Aim: The aim of this study was to determine the association between tobacco use and other lifestyle factors among schoolchildren in Tunisia. Methods: We conducted a 2009/2010 cross-sectional questionnaire survey of 4003 randomly selected school children aged 13 years old (7th and 9th grades) to evaluate their knowledge, attitudes towards, and beliefs about the three risk factors for chronic disease (unhealthy diet, physical inactivity, and tobacco use). Written informed consent was obtained from each child's parents who allowed their child to participate. Results: The mean age of our sample was 13.36±1.28 years. The proportions of daily smokers were 2.2% and 0.1% among boys and girls, respectively. The proportions of irregular smokers were 9.1% and 1.5% among boys and girls, respectively. In our population, 19.1% (n=767) had ever experimented to smoke, with 29.8% among boys and 9% among girls (p<0.001). The proportions of schoolchildren who reported daily participation in physical activity were different between smokers and nonsmokers with 17.7% and 11.5%, respectively (p=0.03). Concerning eating habits, there was no significant difference in the consumption of fruits and vegetables; however, smokers frequently ate more high fat foods and in fast food restaurants. Similar results were found while comparing regular smoking children with those who experimented but who never became hooked on smoking. Conclusion: This study and previous research suggest the importance of early intervention in adolescents on smoking and combing these efforts with interventions focusing on physical activity and dietary habit

Clustering of chronic disease risk factors with tobacco smoking habits among adults in the work place in Sousse, Tunisia

Introduction: The aim of our study was to explore the major non-communicable risk factors (unhealthy diet, sedentarily, alcohol consumption) of smokers and nonsmokers in workplaces. Methods: A cross-sectional study was derived from an initial assessment in workplaces which was part of a community-based intervention to prevent chronic disease risk factors conducted in 2009 in the region of Sousse, Tunisia. The surveyed subjects were employees in six factories spread across three delegations in the region. Overall, 1770 of 2250 employees participated in the assessment. In this study, the clustering of non-communicable diseases risk factors with smoking habits was made only for male employees including in this study 1099 among 2250. Data were collected at worksites by a questionnaire, via interview or self-report .The main items assessed socio-demographics characteristics, smoking status, eating habits, level of physical activity and alcohol use of the participants. Results: The percentage of male smokers was 54.0%(n=594). Their average age of daily smoking initiation was 19.22 (±4.24 years). The percentage of male smokers consuming 5 fruits and vegetables per day was significantly lower than nonsmokers (57.2% vs 63.5%, p=0.04). The proportion of male smokers consuming alcohol was about three times that of nonsmokers (16.5% vs 5.8%, p=0.001). The proportion of male employees who agree with anti-smoking laws in work places was higher for nonsmokers than for smokers. Conclusion: A strong association existed between smoking and risky lifestyles factors in the work place. Such findings are potentially useful in directing intervention efforts regarding smoking cessation in occupational settings.Pan African Medical Journal 2016; 2

Assessment of the validity of self-reported smoking status among schoolchildren in Sousse, Tunisia

Introduction: Tobacco use, which begins in adolescence and childhood and continues in later life, is the major avoidable risk for non-communicable diseases and death in the world. Self-reports have frequently been used to estimate smoking prevalence and health consequences. This study explores the validity of self-reports of smoking behavior among schoolchildren in Tunisia. Materials and methods: This study was conducted in March 2014 among a sample of 147 schoolchildren randomly selected. Data concerning the smoking habit were collected by a questionnaire designed for the purposes of this work. Then, exhaled CO, a biochemical marker of smoke exposure, was measured using piCO+ Smokerlyzer® breath CO monitor among participants. Sensitivity and specificity of self-reports were calculated. Results: The prevalence of reported smoking was 9.5% with 16.7% and 1.7% respectively among boys and girls. Their mean age was 14.5±1.28 years old. When considering 4 ppm as the cut-off level of breath CO, sensitivity and specificity of self-reports were 100% and 93.7%, respectively. But at a breath CO cut-off of 3 ppm, self-reporting was 62.5% sensitive and 93.5% specific. Conclusion: According to our findings, we suggest that self-reports can be considered as a good tool to be used with a reasonable confidence to assess the smoking status
