To explore the relationship between physical activity, outdoor activities, and symptoms of anxiety and depression among male and female college students, and provide recommendations for scientific prevention and control.
A stratified cluster random sampling method was used to select 5 152 college students from grades 1-3 across 20 universities in Chengdu. The questionnaire was based on the National Survey on Common Diseases and Health Influential Factors among Students. Chi-square or linear trend chi-square tests were used to compare categorical data, and binary logistic regression was employed to analyze associations.
Among males, the proportions of those who engaged in moderate-to-vigorous physical activity (MVPA) at least 60 minutes daily for 0 days, 1-2 days, and ≥3 days in the past week were 19.39%, 30.88%, and 49.73%, respectively. Among females, the corresponding proportions were 40.39%, 39.53%, and 20.07%. Regarding daily outdoor activity duration, 18.67% of males spent <1 hour/day, 36.42% spent 1-2 hours/day, and 44.91% spent ≥2 hours/day; among females, these proportions were 25.96%, 33.75%, and 40.29%, respectively. Differences in the detection rates of anxiety, depression, and comorbidity were observed among male and female students with varying levels of physical activity and outdoor activity. Moreover, as the frequency or duration of activity increased, the detection rates showed a decreasing trend. Multivariate analysis showed that, compared to male students who engaged MVPA for 0 days in the past week, those who completed 1-2 days/week or ≥3 days/week of MVPA had a lower risk of anxiety (1-2 days/week: aOR=0.75, 95% CI:0.58-0.98; ≥3 days/week: aOR=0.60, 95% CI:0.47-0.78) and depression (1-2 days/week: aOR=0.67, 95% CI:0.48-0.93; ≥3 days/week: aOR=0.54, 95% CI:0.39-0.75). Compared to female students with less than 1 hour/day of outdoor activity, those with 1-2 hours/day or ≥2 hours/day of outdoor activity had a lower risk of anxiety (1-<2 hours/day: aOR=0.77, 95% CI:0.62-0.95; ≥2 hours/day: aOR=0.81, 95% CI:0.66-0.99) and depression (1-<2 hours/day: aOR=0.58, 95% CI:0.44-0.77; ≥2 hours/day: aOR=0.55, 95% CI:0.42-0.72).
Emotional regulation in male students may be more closely matched with the mechanism of MVPA, while emotional regulation in female students may align better with outdoor activities. It is advisable to provide gender-specific intervention scenarios to improve mental health.
