The total number of participants selected was 961 (581 female and 380 male). RESULTS: = 0.001) correlated significantly with physical activity level reduction during the pandemic. The proportion of people who reduced their physical activity was greater among those who were very active than those who were active (adjusted prevalence ratio aPR: 0.65 confidence interval (CI): 0.52-0.80) or insufficiently active aPR: 0.39 (0.18-0.82). The proportion of people who reduced their physical activity was greater among those who received a salary less than minimum wage (MW) than those who received a salary between three to six times minimum wage (aPR: 0.50 (CI 0.35-0.70) or more than 6 MW (aPR: 0.56 (CI 0.40-0.79). CONCLUSIONS: A higher prevalence of Brazilians residing in the city of São Paulo reduced their physical activity who had a vigorous level of physical activity prior to the pandemic and who received less than a MW.
