Are longitudinal reallocations of time between movementbehaviours associated with adiposity among elderly women? Acompositional isotemporal substitution analysis

Original language description

Background: This study aimed to use compositional data analysis to: (1) investigate the prospective associations betweenchanges in daily movement behaviours and adiposity among elderly women; and (2) to examine how the reallocation of timebetween movement behaviours was associated with longitudinal changes in adiposity. Subjects/methods: This is a 7-year longitudinal study in Central European older women (n=158, baseline age 63.9 ± 4.4years). At baseline and follow-up, light-intensity physical activity (LIPA), moderate-to-vigorous physical activity (MVPA)and sedentary behaviour were measured by accelerometer and body adiposity (body mass index [BMI], body fat percentage[%BF]) was assessed from measured height and weight and bioelectrical impedance analyser. Compositional regression withrobust estimators and compositional longitudinal isotemporal substitution analysis explored if, and how, changes inmovement behaviours were associated with adiposity. Results: Over 7 years, the prevalence of obesity in the sample increased by 10.1% and 14.6% according to BMI and %BF,respectively, and time spent in sedentary behaviour increased by 14%, while time spent in LIPA and MVPA decreased by14% and 21%, respectively. The increase in sedentary behaviour at the expense of LIPA and MVPA during the 7-year periodwas associated with higher BMI and %BF at follow-up (bothp&lt; 0.01). The increase in LIPA or MVPA at the expense ofsedentary behaviour was associated with reduced BMI and %BF at follow-up. In our sample, the largest change in BMI(0.75 kg/m2; 95% confidence interval [CI]: 0.37–1.13) and %BF (1.28 U; 95% CI: 0.48–2.09) was associated with long-itudinal reallocation of 30 min from MVPA to sedentary behaviour. Conclusions: We found an association between longitudinal changes in daily movement behaviours and adiposity amongelderly women in Central Europe. Ourfindings support public health programmes to increase or maintain time spent inhigher-intensity physical activity among elderly women.
