Description
Summary:OBJECTIVETo evaluate the prevalence and incidence of insufficient physical activity in Brazilian adolescents and identify the most affected subgroups during the pandemic.METHODSThis study used data from the "ConVid Adolescents - Behavior Survey", which evaluated the behavior of 9,470 Brazilian adolescents during the period of social restriction due to the COVID-19 pandemic in 2020, through a self-administered online questionnaire. Participants were invited through a virtual "snowball" sampling procedure. Information was reported on the frequency of physical activity before and during the pandemic. The exposure variables used were gender, age group, race/skin color, region of Brazil, type of school, maternal education, financial difficulties during the pandemic, and social restrictions. Logistic regression models were used.RESULTSAdolescents engaged in less physical activity during the pandemic, as the prevalence of insufficient physical activity increased from 71.3% in the previous period to 84.3% during the pandemic. The incidence of insufficient physical activity during the pandemic was 69.6%. The subgroups of adolescents most affected were those who self-declared as black or with dark skin color, reported financial difficulties during the pandemic, lived in the Southeast and South regions of the country, and practiced intense or complete social distancing.CONCLUSIONHigh incidences of insufficient physical activity were observed among Brazilian adolescents during the COVID-19 pandemic. It is recommended that further studies explore periods after those analyzed to identify the behavioral dynamics of adolescents upon returning to in-person activities.
