Abstract
BackgroundTobacco smoking, hazardous drinking and physical inactivity during adolescence are risk factors that are associated with poorer health in adulthood. The identification of subgroups of young people with a high prevalence of one or more of these risk factors allows an optimised allocation of preventive measures. This study aimed at investigating hazardous drinking, tobacco smoking and physical inactivity as well as their associations and demographic predictors in vocational school students.MethodsOut of 57 contacted vocational schools in Switzerland, a total of 24 schools participated in a survey assessing gender, age, immigrant background, educational attainment and vocational field as well as the above mentioned health risk factors. Out of the 2659 students present in 177 included vocational school classes, 2647 (99.5%) completed the survey. Binary logistic regression analyses were conducted to investigate the demographic predictors of each health risk factor and a multinomial logistic regression analysis was conducted to investigate predictors of different risk factor combinations.ResultsOf the surveyed students, 79.4% showed at least one risk factor, 43.6% showed two or more and 9.6% showed all three health risk factors. Hazardous drinking was more prevalent in male, physical inactivity was more prevalent in female vocational school students. The proportion of students with low physical activity and tobacco smoking increased with increasing age. While the combination of hazardous drinking and tobacco smoking was higher in males, the other risk factor combinations were observed particularly among females.ConclusionsMultiple risk factors were ascertained in a significant proportion of vocational school students. Specifically, tobacco smoking and hazardous drinking were coexistent. The study underlines the need for preventive measures in specific subpopulations of adolescents and young adults with lower educational level.
Highlights
Tobacco smoking, hazardous drinking and physical inactivity during adolescence are risk factors that are associated with poorer health in adulthood
The study revealed three main findings: (a) Four out of five vocational school students showed at least one of the investigated health risk factors, hazardous drinking, tobacco smoking, or physical inactivity. (b) Multiple risk factors were ascertained in a significant proportion of vocational school students
Hazardous drinking was more prevalent in male, physical inactivity was more prevalent in female vocational school students
Summary
Hazardous drinking and physical inactivity during adolescence are risk factors that are associated with poorer health in adulthood. This study aimed at investigating hazardous drinking, tobacco smoking and physical inactivity as well as their associations and demographic predictors in vocational school students. Use of substances and physical inactivity during adolescence are associated with poorer health in adulthood. A low level of physical activity during adolescence and International school surveys conducted in secondary schools, such as the Health Behaviour in School Age Children (HBSC; [5]) or the European School Survey Project on Alcohol and Other Drugs (ESPAD; [6]), provide data regarding health behaviour and the prevalence of health risk factors for children between the ages of 11 and 16 years. Little is known about health risk behaviours in adolescents and young adults between the ages of 16 and 20 years with a broader spectrum of educational levels. Vocational school students are typically characterised by heterogeneous educational levels, including a significant proportion with little or no educational attainment
