Cross-sectional associations of leisure and transport related physical activity with depression and anxiety.

BACKGROUND

Previous evidence supports the notion that the physical activity (PA) domain (leisure-time or transport), and the amount of time spent in PA, influence the association of PA with depressive and anxiety symptoms. However, no study evaluated the associations of different volumes of leisure-time PA (LTPA) and transport PA (TPA) with prevalent depression, anxiety, and co-occurring depression and anxiety (D&A) disorders.

AIM

To investigate the associations between different volumes of LTPA and TPA with prevalent depression, anxiety, and D&A.

METHODS

Cross-sectional study using baseline data of the ELSA-Brasil cohort. The International Physical Activity Questionnaire (IPAQ) long-form was used to assess PA levels in each domain. The Clinical Interview Scheduled Revised (CIS-R) was used to diagnose prevalent depressive, anxiety, and D&A disorders. Logistic regressions, adjusting for confounding factors, were employed. Results are expressed as adjusted odds ratios (aOR) and 95% confidence intervals (CI).

RESULTS

A total of 14,381 adults (54.5% female, 67.5% aged 45-64 years) were assessed. T60-89min/week >300min/week p < 0.001). High volumes of LTPA were associated with a lower prevalence 270-299min/week; >300 minutes60-89min/week volumes of TPA were associated with lower prevalence of depression.

LIMITATIONS

Cross-sectional design and self-reported PA. Lack of assessment of sedentary behaviour or occupational PA.

CONCLUSIONS

The present study highlights the importance of contextual factors in the association between PA and mental health, particularly at higher levels.
