The relationship between physical activity and mental health among adolescents in six middle-income countries: A cross-sectional study

Physical inactivity and poor mental health are emerging worldwide youth problems. Using the Global School-based Health Survey, this secondary data analysis study examined the link between physical activity and adolescent mental health among 23,372 adolescents between 11 and 17 years of age in six middle-income countries. The authors assessed physical activity by participation in (a) exercise for 60 min and (b) walking/biking in any day of a week in the past 7 days. The authors assessed mental health by the presence of (a) loneliness, (b) anxiety, (c) depression, (d) suicidal ideation, and (e) suicide attempts in the past 12 months. There was a low prevalence of physical activity among the participants. In general, there was a low prevalence of 12-month mental health problems among adolescents. Further research may incorporate physical activity to promote positive youth mental health for possible cost-effective interventions.
