The Associations Of Objectively-determined Sleep, Sedentary Behavior, And Physical Activity In Older Women

ABSTRACTBackgroundTo investigate the effect of COVID-19 home confinement on levels of physical activity, sedentary behavior and health-related quality of life (HRQL) in older women previously participating in exercise and educational programs.Methods64 older women (age = 72±5 ys) who participated in a physical exercise/educational program and adhered to government home confinement recommendations have their levels of physical activity, sedentary behavior and HRQL assessed before and during (11 to 13 weeks after introduction of government recommendations to reduce virus transmission) COVID-19 pandemic.ResultsThere were significant reductions in total physical activity (−259 METs/week, P = 0.02), as a result of a ∼17.0 % reduction in walking (−30.8 min/week, P = 0.004) and ∼41.8 % reduction in vigorous-intensity activity (−29.6 min/week, P < 0.001). Sedentary behavior also increased (2.24 h/week, P < 0.001; 1.07 h/week days, P < 0.001; and 1.54 h/weekend days, P < 0.001). However, no significant change occurred in moderate-intensity physical activity, and HRQL domains and facets, except for an improvement in environment domain.ConclusionHome confinement due to COVID-19 pandemic decreased levels of physical activity and increased levels of sedentary behavior in previously active older women who participated in an educational program. However, there were no significant changes in HRQL. These results suggest that educational programs promoting healthy behaviors may attenuate the impact of home confinement in older women.

Background: Evidence on sedentary behavior and cardiovascular disease (CVD) is largely based on self-reported sedentary time. Furthermore, how sedentary time is accumulated (in longer vs. shorter bouts) may be related to CVD risk but has not been tested. Methods: Women (n=5638, mean age=79±7) with no history of myocardial infarction or stroke wore accelerometers for 4-7 days and were followed for up to 4 years for incident CVD. Hazard ratios (HR) and 95% confidence intervals (CIs) for CVD and coronary heart disease (CHD) events were estimated across quartiles of sedentary time and mean sedentary bout duration using Cox proportional hazard models adjusting for covariates. Separate models evaluated associations after adding moderate-to-vigorous physical activity (MVPA) and possible mediators: body mass index, diabetes, hypertension, systolic blood pressure, fasting glucose, HDL-cholesterol, and triglycerides. We then tested whether mean bout duration was associated with increased risk for CVD and CHD among women with above median sedentary time (≥10hr/day). Results: Covariate-adjusted HRs for CVD and CHD increased across quartiles of both sedentary time and mean bout duration (Table). All CHD associations remained significant but attenuated after adjustment for possible mediators. After adjustment for MVPA, highest vs. lowest quartile HRs (CI) for CHD were 1.6 (0.7-3.4; p-trend = .08) for sedentary time and 1.8 (0.9-3.5; p-trend = .047) for mean bout duration. Among women with high sedentary time, the HRs (CI) comparing the 75 th vs. 25 th percentile of mean bout duration were 1.05 (0.95-1.15) for CVD and 1.16 (1.01-1.34) for CHD. Conclusions: Both sedentary time and mean bout duration showed independent, dose-response associations with increased risk of CVD and CHD events in older women. Among women with high sedentary time, longer mean bout duration was associated with higher CHD risk. Taken together, this provides evidence that both total sedentary time and the way it is accumulated are predictive of incident CHD.

Sedentary Behaviors

The search for determinants of adiposity gain in older women has become vitally important. This study aimed to (1) analyze the adiposity gain based on the participants’ age and (2) determine the prospective associations of baseline intrapersonal, built environment, physical activity, and sedentary behavior variables with the adiposity gain in older women. This was a seven-year prospective study (baseline: 2009 to 2012; follow-up: 2016 to 2019) in older women (n = 178, baseline age = 62.8 ± 4.1 years). Baseline and follow-up adiposity (bioelectrical impedance) and baseline physical activity, sedentary behavior (accelerometers), and intrapersonal and built environment (Neighborhood Environment Walkability Scale questionnaire) variables were included. The body mass index (BMI) increment tended to be inversely associated with the women’s age (p = 0.062). At follow-up, 48, 57, and 54% of the women had a relevant increase (d-Cohen > 0.2) in their BMI, percentage of body fat, and fat mass index, respectively. The women that spent ≥8 h/day being sedentary were 2.2 times (1.159 to 4.327 CI95%, p < 0.02) more likely to increase BMI (0.82 to 0.85 kg/m2) than non-sedentary women. No built environment variables were associated with seven-year adiposity gain (all ps > 0.05). A reduction in sedentary time should be promoted for adiposity gain prevention and health preservation in older women.
