The Interacting Role of Physical Activity and Diet Control in Hungarian Adolescents' Substance Use and Psychological Health.

The interacting protective role of diet control and physical activity was examined in understanding adolescents' substance use and psychological health. Questionnaire survey was conducted in Hungary in 2008 ( N = 881). Diet control, physical activity, prevalence of substance use, and psychological health variables were measured. Logistic regression analyses showed that the interaction term of diet control and physical activity significantly increased the odds of self-perceived health, decreased substance use, and influenced the level of optimism, satisfaction with life, and the presence of depressive symptoms. Results indicated that the interaction of diet control and physical activity plays important role in adolescents' health behavior. [ABSTRACT FROM AUTHOR]
