Prospective associations between leisure-time physical activity and adiposity across the transition from middle to old age: a population-based cohort study in Finnish adults 1: Research Unit of Population Health, University of Oulu, Oulu, Finland; 2: Department of Sports and Exercise Medicine, Oulu Deaconess Institute Foundation sr, Oulu, Finland; 3: Gerontology Research Center and Faculty of Sport and Health Sciences, University of Jyväskylä, Jyväskylä, Finland; 4: Medical Research Center Oulu, Oulu University Hospital and University of Oulu, Oulu, Finland; 5: Northern Ostrobothnia Wellbeing Services County, Oulu, Finland; 6: Unit of Health Promotion, Wellbeing Services County of Lapland, Rovaniemi, Finland; 7: Geography Research Unit, University of Oulu, Oulu, Finland; 8: Research Unit of Health Sciences and Technology, University of Oulu, Oulu, Finland Aim: To explore bidirectional prospective associations between leisure-time physical activity (LTPA) and multiple adiposity indicators from middle to old age, and to assess sex differences in these associations. Methods: Data were drawn from the Finnish Oulu45 cohort study (N=682, 56% female). Information about self-reported frequency of LTPA of ≥30min and laboratory-measured adiposity indicators—body mass index (BMI), waist circumference (WC), waist-to-height ratio (WHtR), and waist-to-hip ratio (WHR)—were collected at approximately ages 57 and 70. Multi-group cross-lagged panel models were used to assess sex-specific associations between LTPA and adiposity indicators, adjusted for socio-demographic and lifestyle confounders. Results: In men, weak negative cross-sectional associations were found between LTPA and all adiposity indicators at both timepoints (r= −0.12 to −0.28, p≤0.039). In women, only LTPA and WHR at age 70 were significantly associated (r=−0.120, p=0.031). No cross‑lagged effects were observed from LTPA at 57 to adiposity at 70. In contrast, higher values in all adiposity indicators at 57 predicted lower LTPA at 70 in men (standardized coefficients: BMI: -0.123, WC: -0.145, WHtR: -0.160, WHR: -0.145; p≤0.035) and women (BMI: -0.289, WC: -0.321, WHtR: -0.319, WHR: -0.274; p<0.001). Sex did not moderate these associations (p≥0.2). Conclusions: Across the transition from middle to old age, adiposity predicts subsequent leisure-time physical activity frequency but not vice versa, regardless of indicator. Supporting physical activity engagement among middle‑aged adults with elevated adiposity may help reduce functional decline later in life.
