Explaining educational inequalities in adolescent life satisfaction: Do health behaviour and gender matter?

Objectives: There is little evidence on the explanation of health inequalities based on a gender sensitive perspective. The aim was to investigate to what extent health behaviours mediate the association between educational inequalities and life satisfaction of boys and girls. Methods: Data were derived from the German part of the Health Behaviour in School-aged Children (HBSC) study 2010 (n = 5,005). Logistic regression models were conducted to investigate educational inequalities in life satisfaction among 11- to 15-year-old students and the relative impact of health behaviour in explaining these inequalities. Results: Educational inequalities in life satisfaction were more pronounced in boys than in girls from lower educational tracks (OR 2.82, 95 % CI 1.97-4.05 and OR 2.30, 95 % CI 1.68-3.14). For adolescents belonging to the lowest educational track, behavioural factors contributed to 18 % (boys) and 39 % (girls) in the explanation of educational inequalities in life satisfaction. Conclusions: The relationship between educational track and life satisfaction is substantially mediated by health-related behaviours. To tackle inequalities in adolescent health, behavioural factors should be targeted at adolescents from lower educational tracks, with special focus on gender differences.
