- Background: Retirement transition has shown to associate with changes in physical activity (PA) and self-rated health (SRH), but their interrelationship is less studied. The aim was to investigate changes in accelerometer measured total PA, moderate-to-vigorous PA (MVPA) and sedentary time across retirement transition as a predictor of self-rated health. Methods: Data from the Swedish Retirement Study and the Finnish Retirement and Aging study was harmonized and pooled. Data from three waves (about 12 months apart) was included: one pre-retirement (wave 1) and two post-retirement follow-ups (wave 2-3). Totally 245 participants (27% men) were included. Thigh-worn accelerometers were used to collect data for PA variables (wave 1-2), and SRH was obtained from the questionnaire (wave 1-3). Results: Between wave 1 and 2, total PA decreased with 11 (CI:-22;-1) minutes per day, MVPA was stable (0 [CI:-3;3] min), and sedentary time decreased non-significantly with 9 (CI:-20;1) minutes. SRH changed between all three waves (all, p<0.001). At pre-retirement, 10 more minutes of MVPA was associated with greater odds of better SRH when adjusting for accelerometer wear-time, cohort, sex and age, and occupational status (OR:1.11 (95%CI:1.02-1.22)). This association was no longer statistically significant when additionally adjusting for marital status, BMI, and smoking. No significant associations were observed between changes in the PA variables during retirement transition, and SRH at post-retirement follow-ups. Conclusion: This study showed a cross-sectional association between MVPA and greater odds of reporting better SRH before retirement. No longitudinal associations were observed between changes in the PA variables from before to after retirement and later change in SRH

- Introduction Physical activity, sedentary behavior, and sleep, that is, 24-h movement behaviors, often change in the transition from work to retirement, which may affect cardiometabolic health. This study investigates the longitudinal associations between changes in 24-h movement behaviors and cardiometabolic biomarkers during the retirement transition.Methods Retiring public sector workers (n = 212; mean (SD) age, 63.5 (1.1) yr) from the Finnish Retirement and Aging study used a thigh-worn Axivity accelerometer and filled out a diary to obtain data on daily time spent in sedentary behavior (SED), light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA), and sleep before and after retirement (1 yr in-between). Cardiometabolic biomarkers, including LDL-cholesterol, HDL-cholesterol, total/HDL-cholesterol ratio, triglycerides, C-reactive protein, fasting glucose, and insulin, were measured. Associations between changes in 24-h movement behaviors and cardiometabolic biomarkers were analyzed using compositional robust regression and isotemporal substitution analysis.Results Increasing LPA in relation to remaining behaviors was associated with an increase in HDL-cholesterol and decrease in total/HDL-cholesterol ratio (P < 0.05 for both). For instance, reallocation of 30 min from sleep/SED to LPA was associated with an increase in HDL-cholesterol by 0.02 mmol·L−1. Moreover, increasing MVPA in relation to remaining behaviors was associated with a decrease in triglycerides (P = 0.02). Reallocation of 30 min from SED/sleep to MVPA was associated with 0.07–0.08 mmol·L−1 decrease in triglycerides. Findings related to LDL-cholesterol, C-reactive protein, fasting glucose, and insulin were less conclusive.Conclusions During the transition from work to retirement, increasing physical activity at the expense of passive behaviors was associated with a better lipid profile. Our findings suggest that life transitions like retirement could be utilized more as an optimal time window for promoting physical activity and health.
