Physical activity and sedentary behavior in older adults in southern Sonora: a comparative analysis by sex

Introduction: Population aging poses critical challenges for public health. Although regular exercise mitigates functional decline and prevents chronic diseases, physical inactivity is prevalent among older adults. In Mexico, only 1.5% of this population meets international physical activity recommendations. This study examines physical activity levels in Ciudad Obregón to inform strategies that promote independence. Objective: To analyze the level of physical activity among older adults in Ciudad Obregón, differentiating by gender. Methodology: A non-experimental cross-sectional design with a descriptive scope was used. The sample consisted of 135 older adults from Cajeme (66.6%), Navojoa (23.5) and Huatabampo (9.9%) (40.7% female, 59.3% male), with an average age of 68 years (SD ± 3.09). The short version of the IPAQ (International Physical Activity Questionnaire) was used as the measurement instrument. The Mann-Whitney U test was applied to analyze gender differences. Results: Significant differences were found in the level of moderate physical activity and sedentary behaviors. Conclusions: The study objective was achieved, identifying a pattern of active sedentary behavior predominantly among men. Although men engage in more moderate-intensity physical activity, they also exhibit higher levels of sedentary behavior. The lack of vigorous physical activity in both sexes increases cardiovascular risk, necessitating interventions that take psychosocial factors into account.
