Prevalence and Determinants of Susceptibility to Tobacco Smoking among Students in The Gambia.

Introduction: Smoking is the biggest preventable cause of death, and kills about 7 million people annually. As smoking prevalence is falling in developed countries, tobacco businesses are turning to low and middle-income countries (LMICs) to generate new tobacco markets. To prevent young people from initiating smoking and becoming regular smokers it is important to understand the causes of susceptibility to smoking. In this study we report a nationwide survey of the prevalence and risk factors of smoking susceptibility among students aged 12-20 in The Gambia.

Methods: We used two-stage cluster random sampling to select students in secondary schools throughout The Gambia, and questionnaire to collect data on demographic characteristics and indicators on susceptibility to initiating smoking.

Results: Among the total sample of 10,289 students, 9831(96%; 55.6% girls and 44.4% boys, (aged 12-20 years) non-smokers were included in the analysis. Of these, 3,333 (33.9%) were found to be susceptible to smoking. Smoking susceptibility was more common among students attending grant-aided schools, non-Muslims, who had smoking allowed at home, had family members or friends who smoke, were sent to purchase cigarettes, had poor knowledge of the harmful effects of smoking, noticed point-of-sale tobacco advertisements and who had positive attitudes towards smoking.

Conclusions: This study shows that susceptibility to smoking is common among students and associated with preventable exposures. Although based on cross-sectional data these findings suggest that raising students' awareness of the harmful effects of smoking and reducing the prevalence of adult smoking, extending tobacco advertising restrictions to include point-of-sale, are all important to preventing the uptake of smoking among students.

Implications: This is the first study to provide detailed data on smoking susceptibility and risk factors in a nationally representative sample of young people in The Gambia. Our findings show that susceptibility to smoking is relatively high and associated with preventable measures. Our results also identify an urgent need to broaden the ban on tobacco advertising to explicitly include point-of-sale advertisements. These findings provide valuable information for tobacco control policies and evidence to enable targeted intervention for young people most at risk of initiating smoking.
