Hubungan status gizi, aktivitas fisik, dan screen time dengan daytime sleepiness pada remaja di SMPN 47 Bandung

Background: Daytime sleepiness may impair adolescents’ concentration and alertness during learning. Nutritional status, physical activity, and screen time may be associated with this condition. Objectives: To examine associations of nutritional status, physical activity, and screen time with daytime sleepiness among adolescents. Methods: This cross-sectional study involved 94 adolescents aged 13–15 years at SMPN 47 Bandung on January 26, 2026, selected using stratified random sampling. Data were collected using the Cleveland Adolescent Sleepiness Questionnaire, Physical Activity Level assessment, a modified Adolescent Sedentary Activity Questionnaire, and anthropometric measurements. Analyses used chi-square, Fisher’s exact test, and multiple logistic regression. Results: Bivariate associations were significant for BMI-for-age (p = 0.002) and body fat percentage (p = 0.013), but not physical activity (p = 0.361) or screen time (p = 0.636). In the model adjusted for sex, no significant associations were found for BMI-for-age (OR = 3.597; 95% CI: 0.976–13.259; p = 0.054), body fat percentage (OR = 2.435; 95% CI: 0.459–12.914; p = 0.296), physical activity (OR = 2.243; 95% CI: 0.424–11.874; p = 0.342), or screen time (OR = 4.697; 95% CI: 0.427–51.604; p = 0.206). Conclusion: Nutritional indicators were associated with daytime sleepiness in bivariate analyses, but these associations were not statistically significant in the adjusted model. Physical activity and screen time showed no significant associations.
