ABSTRACT Objective To verify the association of changes on physical activity levels during coronavirus disease 2019 (COVID-19) outbreak of individuals with normal weight and overweight/obesity, and the influence of sex in this relationship. Methods This cross-sectional study (survey research) was conducted in Brazil between May 5 and May 17, 2020. Participants (n=1,828 / 1,062 women >18 years) were invited through social media to answer a structured questionnaire via Google Forms. The online assessment included self-reported responses to questions on physical activity, overall health, weight, and height. Binary logistic regression analyzed the relationship between overweight/obesity (body mass index ≥25kg/m2), the impact of COVID-19 on physical activity level, and the influence of sex. Results Compared to normal weight people, those with overweight/obesity practice less moderate to vigorous physical activity (p<0.001). There were associations between women and men with overweight/obesity and the impact of COVID-19 on the physical activity practice compared to normal weight people, adjusted by age, education level, social isolation, and previous physical activity level (p<0.017). Conclusion The study found an association of weight and changes in physical activity levels. Individuals with overweight/obesity were more likely to have a lower physical activity level during COVID-19 pandemic, regardless of sex.

RESUMO Objetivo Investigar o impacto da pandemia de coronavírus 2019 sobre o nível de atividade física e comportamento sedentário entre brasileiros com idade ≥18 anos. Métodos Uma pesquisa on-line foi distribuída por meio de mídias sociais entre 5 e 17 de maio de 2020. Os participantes responderam a um questionário estruturado no Google Forms, que avaliou o nível de atividade física e comportamento sedentário de adultos no Brasil durante a pandemia. Resultados Idade (RC: 0,98; IC95%: 0,97-0,99), doença crônica (RC: 1,29; IC95%: 1,03-1,63), inatividade física antes da pandemia de coronavírus 2019 (RC: 2,20; IC95%: 1,78-2,72) e excesso de peso (RC: 1,34; IC95%: 1,09-1,65) apresentaram maior risco de impacto no nível de atividade física. O aumento do tempo sentado foi associado a indivíduos mais velhos (RC: 0,97; IC95%: 0,96-0,98), inatividade (RC: 1,51; IC95%: 1,16-1,96), doença crônica (RC: 1,65; IC95%: 1,23-2,22), maior número de dias no isolamento social (RC: 1,01; IC95%: 1,00-1,02) e níveis de escolaridade mais altos (RC: 1,87; IC95%: 1,26-2,78). Conclusão Nossos resultados demonstraram que a idade, a presença de doenças crônicas e a inatividade física antes do isolamento social tiveram maior risco de impacto na redução do nível de atividade física e maior tempo sentado durante a pandemia de coronavírus 2019.

ABSTRACT Objective To investigate the impact of the coronavirus 2019 pandemic on physical activity levels and sedentary behavior among Brazilians residents aged ≥18 years. Methods An online survey was distributed through a social media platform between May 5 and 17, 2020. Participants completed a structured questionnaire in Google Forms, which assessed the physical activity level and sedentary behavior of adults in Brazil during the pandemic. Results Age (OR: 0.98; 95%CI: 0.97-0.99), chronic disease (OR: 1.29; 95%CI: 1.03-1.63), physical inactivity before the coronavirus 2019 pandemic (OR: 2.20; 95%CI: 1.78-2.72) and overweight (OR: 1.34; 95%CI: 1.09-1.65) showed higher risk of impact on physical activity levels. Increased sitting time was associated with older individuals (OR: 0.97; 95%CI: 0.96-0.98), inactivity (OR: 1.51; 95%CI: 1.16-1.96), chronic disease (OR: 1.65; 95%CI: 1.23-2.22), higher number of days in social isolation (OR: 1.01; 95%CI: 1.00-1.02) and higher schooling levels (OR: 1.87; 95%CI: 1.26-2.78). Conclusion Our results demonstrated that advanced age, chronic disease and physical inactivity before social isolation had a greater risk of impact on reduced physical activity levels and increased sitting time during the coronavirus 2019 disease pandemic.
