Increasing Reported Physical Activity Among Australian Adults: Progress Toward a Healthy Older Age.

Abstract

Background/objectives: A globally aging population necessitates public health action that supports healthy aging. Although it is well established that participation in physical activity (PA), sport, and active recreation are important for healthy aging, PA levels remain generally lower among older adults. This study examines trends in physical activities that older adults engage in and identifies disparities in activities across subgroups as defined by age, gender, and socioeconomic status.

Methods: Data from two New South Wales survey data sets (New South Wales Population Health Survey and AusPlay) investigated patterns and trends of PA, sport, and active recreation between 2016 and 2021 among adults aged 65+ years. Weighted prevalence estimates of meeting PA guidelines (≥150 min/week of moderate to vigorous PA), weekly minutes spent walking and doing moderate to vigorous PA, and annual participation rates in specific activities were calculated as weighted proportions. Multivariable logistic regression models included age, gender, and socioeconomic status as independent variables.

Results: Between 2016 and 2021, the proportion of older adults meeting PA guidelines increased (37.8%-51.3%). Adults aged 75+ years, older men, and those living in the least disadvantaged areas experienced greater increases in moderate to vigorous PA.

Conclusions: Older adults' reported PA levels have increased in recent years, highlighting opportunities to prioritize PA promotion in the global agenda to support healthy and active aging. Significance/Implications: This study offers insights into recent trends and noteworthy increases in PA, sport, and active recreation among older Australian adults. These can assist policymakers in developing, evaluating, and implementing population-wide strategies to maintain improved activity levels.
