Leisure time physical activity among older adults in Brazil: a time series analysis of a population-based survey (2009-2020).

Abstract

The practice of leisure time physical activity brings several health benefits, such as the prevention of noncommunicable diseases. Investigating the temporal trend of physical activity practice in older adults by sociodemographic characteristics and geographical regions could be important to plan public health policies and effective interventions. This is a time series study that analyzes the temporal trend of leisure time physical activity among Brazilian older adults with data from 2009 to 2020. For this, we used a sample of 186,097 older adults (≥ 60 years old) obtained from the Risk and Protective Factors Surveillance System for Chronic Noncomunicable Diseases Through Telephone Interview (Vigitel) (2009-2020). Information on leisure time physical activity and sociodemographic and health characteristics were collected. Prais-Winsten regression was used to identify significant trends in the annual variation of the leisure time physical activity indicators. Practice of ≥ 150 minutes/week of moderate intensity leisure time physical activity varied from 23.3% to 27.5% (0.41p.p./year) (2009-2020), with a higher increase during 2015-2020 (0.59p.p./year). The increase in the most recent period occurred among men, aged from 60 to 69 years, with lower educational level, residing in the Northeast Region, and without self-reported chronic diseases. These results may contribute to the evaluation of Brazilian health policies targeting the leisure time physical activity practice in older adults.
