The relationship between physical activity and mental health in a sample of the UK public: A cross-sectional study during the implementation of COVID-19 social distancing measures

Aim: The aim of the present study was to investigate the cross-sectional association between physical activity levels with depressive symptoms, anxiety symptoms, and positive mental well-being in a sample of the UK public social distancing owing to COVID-19. Method: This paper presents pre-planned interim analyses of data from a cross-sectional epidemiological study. Levels of physical activity during COVID-I9 social distancing were self-reported. Mental health was measured using the Beck Anxiety and Depression Inventory. Mental wellbeing was measured using The Short Warwick-Edinburgh Mental Well-being Scale. Participants also reported on sociodemographic and clinical data. The association between physical activity and mental health was studied using regression models. Results: 902 adults were included in this study (63.8% of women and 50.1% of people aged 35-64 years). After adjusting for covariates, there was a negative association between moderate-to-vigorous physical activity per day in hours and poor mental health (OR = 0.88, 95% CI = 0.80-0.97). Similar findings were obtained for moderateto-severe anxiety symptoms, moderate-to-severe depressive symptoms and poor mental wellbeing. Conclusions: In the present sample of UK adults social distancing owing to COVID-19 those who were physically active have better overall mental health. Owing, to the cross-sectional design of the present study the direction of the association cannot be inferred.
