This study was to measure physical activity (PA) and sleep habits among junior high school students in HCMC and identify factors associated with World Health Organization (WHO) recommendations. We performed a cross-sectional study with 1,023 junior high school students were randomly selected. Participants wore wrist-worn accelerometers for seven consecutive days to objectively record PA and sleep using validated methods. Multivariate models were used to identify predictors of achieving WHO recommendations for PA (≥60 min/day moderate-to-vigorous physical activity-MVPA) and sleep (8–10 hours/night). Data completed on 948 students with 47.5% males and the mean age was 12.9 years. Only 35.1% and 42.8% met WHO PA and sleep recommendations, respectively. Boys engaged in significantly more MVPA than girls, while girls spent more time in light activity. Girls also showed better sleep quality—longer sleep duration, higher efficiency, and shorter latency—whereas older adolescents had shorter and less efficient sleep than younger peers. Across all groups, average sleep duration was below WHO recommendations. After adjusting for other factors, boys were significantly more likely than girls to achieve the PA guidelines. Overall, the findings indicate that gender, age, BMI, parental modeling, family encouragement, and supportive school environments are the strongest predictors of whether adolescents meet recommended PA levels. Girls, younger age, overweight/obesity, family sleeping reminders and quiet sleep environment were significant factors of adhering sleep recommendation. Our study revealed the multifactorial interaction of individual, family, and environmental factors in meeting WHO recommended levels for PA and sleep in adolescents. Multidisciplinary interventions are required to promote adolescent behaviors.
