Transition into secondary education and health-compromising behaviours: A longitudinal study

Abstract

Abstract Background We studied the associations of health-compromising behaviours with a transition into secondary education by following a large cohort of Finnish adolescents. Students with a direct (successful) transition into secondary education after the 9th grade (73%) and those with a late transition (7%) were compared. Methods We analysed the following health behaviours in the 7th and 9th grades collected in school surveys in the Helsinki Metropolitan Area: late bed time, irregular breakfast pattern, tooth brushing less than twice a day, monthly alcohol consumption, smoking, regular energy drink consumption, physical activity level under recommendations, and excessive screen time, as well as clustering of these behaviours. Results In logistics regression models (adjusted for gender, school), in the 7th grade all health-compromising behaviors except physical inactivity were related to the late transition, and in the 9th grade energy drink, smoking, breakfast, tooth brushing and screen time. In multivariate models (controlled for academic achievement, immigrant status, language spoken at home, and parents’ education) only bed time was independently associated in both grades. Bed time, breakfast, tooth brushing, alcohol, smoking, and energy drink formed three behavioral clusters -healthy, mixed, and unhealthy lifestyles. The last two predicted the late start in both grades; in multivariate models unhealthy only. Change in academic achievement over time, but not in lifestyle, predicted the transition. Conclusions Students with unhealthy lifestyle are more likely to start secondary education later than those with healthy lifestyle meaning also postponing of their graduation and start of working life. Key messages The unhealthy lifestyle of those who start secondary education later than average, may be one of the mechanisms in the origin of socioeconomic health differences in later life. Healthy lifestyle as early as 13 years predicts successful educational paths.
