Physical Activity Prevalence and Sex-Associated Factors Among University Students During the First Year of the...

The study investigated the prevalence of students meeting moderate-to-vigorous physical activity (MVPA) recommendations and factors associated with MVPA during the first year of the COVID-19 pandemic. A cross-sectional study was conducted with 4059 university students (2200 females [F]) during the lockdown using an electronic form. PA was assessed using the short version of the International Physical Activity Questionnaire (IPAQ-SF). Independent variables included sociodemographic characteristics, knowledge to perform PA, pre-pandemic PA, sedentary behavior (SB), and health self-reports related to the COVID-19 pandemic. Overall, 56% of students met MVPA recommendations (males [M]: 57.7%, F: 54.3%; χ² = 4.703, p = 0.030). Knowledge to perform PA (M: OR = 3.012, 95% CI: 2.413-3.759; F: OR = 2.948, 95% CI: 2.444-3.556) and being physically active before the pandemic (M: OR = 2.651, 95% CI: 2.060-3.412; F: OR = 1.459, 95% CI: 1.079-1.974) increased the likelihood that students attained the MVPA recommendations. In contrast, longer daily exposure to SB was negatively associated with MVPA in both sexes. In this context, the present findings reinforce the relevance of universities as strategic settings for the promotion of PA in middle-income countries, where social and economic vulnerabilities may exacerbate the long-term consequences of physical inactivity.
