RESUMO

(1) Background: As the worldwide aging population is growing, there is a need to embrace the role of physical activity in the anxiety of older people. Objectives: To analyze anxiety in older people practitioners and non-practitioners of physical activity; (2) Methods: ample composed of 690 older people of both genders, unselected volunteers, residing in Brazil, present (as participants or observers) in selected street races in the state of Rio de Janeiro, Brazil, between 30 October 2019, and 12 March 2020. An instrument composed of the sociodemographic questionnaire and questions from the Beck Anxiety Inventory, BAI, and the Physical Activity Inventory for older people, Baecke-Old. Design: Ex-post-facto observational analytical descriptive research; (3) Results: The average age of the sample was in the range of 65 to 69y, 74% female, 94% completed high school, 69% living with the family, 84% practicing physical activity. Anxiety levels were 26% (without), 35% (mild), 21% (moderate), and 18% (severe). The comparison of anxiety showed a difference between the groups of active and sedentary elderly. Logistic regression analysis considering anxiety (yes or no; dichotomous variable) and physical activity (yes or no; dichotomous variable) and Odds Ratio were performed to identify possible influences of the independent variables PA, gender, marital status, and education on anxiety. Only physical activity was associated with anxiety. (4) Conclusions: The sample data of this research point to the conclusion that physical activity influences anxiety levels with 98% certainty, and it is suggested that it be enriched in the future with different studies with different designs. The older people practitioners of physical activity with a high level of education presented as 26% without, 35% mild, 21% moderate, and 18% severe anxiety. More active individuals are less likely to develop anxiety.
