Abstract
Sedentary behavior (SB) and physical activity (PA) are distinct physical behaviors influencing health outcomes, particularly in individuals with type 2 diabetes (T2D). Increased SB is associated with higher cardiometabolic risk, while PA, especially moderate-to-vigorous intensity physical activity (MVPA), is linked to reduced mortality and improved health. Given the diverse sociodemographic context of Brazil, understanding the determinants of SB and PA in Brazilian adults with T2D is essential. To investigate the association of sociodemographic and clinical factors with SB, light-intensity physical activity (LIPA), and MVPA among Brazilian adults diagnosed with T2D, and to assess adherence to MVPA guidelines. This cross-sectional study involved 150 adults. Daily SB and PA were measured using ActiGraph™ triaxial accelerometers over eight days. Sociodemographic and clinical data were collected via questionnaires. Data were analyzed using descriptive statistics, t-tests, chi-square tests, and multivariate linear regression models. Participants spent 48.5% of daily awake time in SB, 47% in LIPA, and <5% in MVPA. Gender significantly influenced SB and LIPA; males spent more time in SB and less in LIPA than females. Employment status also affected LIPA, with unemployed individuals engaging less in LIPA. Sixty-one percent of participants met MVPA guidelines, yet a high sedentary tendency persisted. Sociodemographic factors, particularly gender and employment status, significantly influence SB and LIPA in Brazilian adults living with T2D. Despite adherence to MVPA guidelines, the predominantly SB underscores the need for public health strategies promoting all PA intensities, especially LIPA, to mitigate SB's adverse effects.
