The contextual effect of school satisfaction on health-risk behaviors in Japanese high school students.

BACKGROUND
The importance of school contextual effects on health and well-being among young people is currently recognized. This study examines the contextual effects of school satisfaction as well as the effects of individual-level school satisfaction on health-risk behaviors in Japanese high school students.


METHODS
Self-administered questionnaires were distributed to 3248 students in grades 10 through 12 at 29 public high schools throughout Okinawa, Japan. Using multilevel logistic regression models, the effects of individual- and contextual-level school satisfactions on health-risk behaviors were analyzed. The contextual-level school satisfaction was defined as satisfaction at the school level and was measured using aggregated individual scores. Behaviors studied included current smoking, current drinking, and sexual activity.


RESULTS
Approximately 15%, 6%, and 5% of the total individual differences in smoking, drinking, and sexual behaviors, respectively, occurred at the school level. Students with lower school satisfaction were more likely to engage in health-risk behaviors compared with those with higher school satisfaction. After adjustment for individual-level school satisfaction and other covariates, the odds of smoking and drinking increased with decreasing contextual-level school satisfaction. However, the association of contextual school satisfaction with sexual activity did not reach statistical significance.


CONCLUSIONS
This study showed that individual- and contextual-level school satisfactions affected smoking and drinking behaviors in Japanese high school students. However, no significant association between contextual-level school satisfaction and sexual activity was observed.
