BACKGROUND Health benefits of physical activity (PA) accrue with small increases in PA, with the greatest benefits for those transitioning from inactivity to any level of PA. This study examined whether self-reported PA time in Queensland adults changed between 2004 and 2018. METHODS The Queensland government conducts regular cross-sectional telephone surveys. Between 2004 and 2018, adults aged 18-75 years answered identical questions about their weekly minutes of walking, moderate PA, and vigorous PA. Hurdle regression estimated the average annual change in weekly minutes of PA overall and by activity type, focusing on sociodemographic differences in trends. RESULTS The sample size averaged 1764 (2004-2008) and 10,188 (2009-2018), totaling 107,171 participants aged 18-75 years. Unadjusted PA increased by 10 minutes per week per year (95% confidence interval [CI], 8.8-11.1) overall, with increases for most subgroups. Adjusted PA increased by 10.5 minutes per week per year (95% CI, 9.4-11.7). Trends differed by employment-employed adults and those not in the labor force increased by 14.3 (95% CI, 12.8-15.8) and 2.2 minutes per week per year (95% CI, 0.4-4.0), respectively, with no increase for unemployed adults. The increases were due to both an increased prevalence of doing any activity and an increased average duration among active adults. CONCLUSIONS Since 2004, PA time has increased for Queensland adults, with substantial variability by employment status.
