Association between Physical Activity and Mental Health among School Going Adolescents in Dhulikhel: A Cross-sectional Study

Abstract

Introduction: Physical activity (PA) is important for both physical and mental health. However, many adolescents face mental health problems due to academic pressure, increased screen time, and lack of physical activity. The aim of the study was to find out the association between of physical activity and the presence of depression, anxiety, and stress among school adolescents in Dhulikhel.

Materials and Methods: A cross-sectional study was conducted among 384  students aged 14–19 years from four schools in Dhulikhel using convenience sampling. Physical activity was measured using MVPAQ-A, and mental health was assessed using DASS-Y. Data was analyzed using SPSS version 25.

Results: Among 384 adolescents, the mean age was 15.08 ± 1.09 years, with 50.8% females and 49.2% males. Most adolescents had normal mental  health status (depression: 80.2%, anxiety: 74.7%, and stress: 83.3%), while  68.2% had moderate physical activity. Physical activity was significantly associated with depression (χ² (6) = 21.813, p=0.001), anxiety (χ²(8)=22.149, p=0.005), and stress (χ²(6)=28.331, p<0.001). Higher physical activity levels were associated with better mental health outcomes among adolescents.

Conclusion: Higher physical activity was linked to better mental health 
among adolescents. Schools and public health programs should encourage regular physical activity to improve mental well-being. Further studies are  needed to understand long-term effects and effective interventions.
