ABSTRACT

ABSTRACT BACKGROUND: The COVID-19 pandemic may be having many psychological impacts on people, at both an individual and a community level. OBJECTIVE: To ascertain the relationship between the weekly frequency of physical activity and levels of stress among Brazilian adults during social distancing due to the coronavirus (COVID-19), and the interaction of sex in this association. DESIGN AND SETTING: Cross-sectional study with a descriptive approach conducted at a public university in Curitiba (PR), Brazil. METHODS: 2,000 Brazilian adults (average age 36.4 years; 59.6% women) were recruited according to convenience through digital media. They filled out a questionnaire in electronic format that asked for sociodemographic information, health data, food consumption data, weekly frequency of physical activity and stress levels on the 10-item Kessler psychological distress scale. Descriptive statistics and regression analyses were used to evaluate the data. RESULTS: Associations were observed for the following correlations male sex * no physical activity (odds ratio (OR) 4.35; 95% confidence interval (CI) 1.14-16.67); female sex * physical activity 4 or 5 times a week (OR 7.86; 95% CI 2.28-27.05); female sex * physical activity 3 times a week (OR 7.32; 95% CI 2.09-25.58); female sex * physical activity 1 or 2 times a week (OR 14.57; 95% CI 4.28-49.57); and female sex * no physical activity (OR 24.17; 95% CI 7.21-80.97). CONCLUSION: The lower the weekly frequency of physical activity during the period of social distancing was, the greater the chances of having stress levels were, especially for women.
