	abstract = {Background: Evidence on physical activity (PA) and transitions out of full-time employment in middle-to-older age is mainly cross-sectional and focused upon retirement. The purpose was to examine trajectories in PA before and after transitions out of full-time employment. Methods: Data were obtained for 5,754 people in full-time employment aged 50-75 from the US Health and Retirement Survey. Logistic regression was used to examine trajectories in twice-weekly participation in light, moderate and vigorous PA among those transitioning to part-time work, semi-retirement, full retirement, or economic inactivity due to disability, in comparison to those remaining in full-time employment. Results: Twice weekly participation in vigorous and light physical activity changed little for those who remained in full-time employment, while moderate physical activity decreased between baseline and follow-up (OR 0.95, 95 \% CI 0.91, 0.99). Differences in physical activity according to transitional categories at follow-up were evident. Baseline differences in physical activity across all intensities were greatest among participants transitioning from full-time to part-time employment compared to those who remained in full-time employment throughout the study period (vigorous OR 1.41 95 \% CI 1.23, 1.61; moderate OR 1.28 95 \% CI 1.12, 1.46; light OR 1.29 95 \% CI 1.12, 1.49). Those transitioning to unemployment were already among the least physically active at baseline, irrespective of intensity (albeit, with 95 \% CIs spanning unity). Those transitioning to full-time retirement were also among the least active (e.g. vigorous OR 0.71 95 \% CI 0.61, 0.81; moderate OR 0.80 95 \% CI 0.71, 0.90). Declines in physical activity were reported for those transitioning to economic inactivity due to a disability (vigorous OR 0.29 95 \% CI 0.14, 0.64; moderate OR 0.56 95 \% CI 0.33, 0.95; light OR 0.34 95 \% CI 0.19, 0.63). Physical activity increased regardless of intensity among participants transitioning to semi-retirement (p > 0.05) and full retirement (e.g. vigorous OR 1.28 95 \% CI 1.09, 1. 51; moderate OR 1.24 95 \% CI 1.07, 1.43). Light physical activity increased for those transitioning to unemployment (OR 1.40 95 \% CI 1.02, 1.93), though less change was evident in moderate or vigorous physical activity. Conclusions: The amount and intensity of PA varies by the type of transition out of full-time employment among people in middle-to-older age.},
