Objectives: To examine the association between health behavior indicators, school contentment, and academic achievement.
Methods: Structural equation modeling with 5810 adolescents.
Results: Our model explained 36% of the variance in academic achievement and 24% in school contentment. BMI and sedentary lifestyle were negatively related to school contentment and academic achievement, but physical activity was positively related to school contentment and academic achievement (P < .01). School contentment was strongly related to academic achievement but only a weak mediator of the health behavior indicators.
Conclusion: Findings may inform the efforts to improve academic achievement and the general health status of youth.
