研究问题
What remains absent, however, is a scoping review that charts all three movement behaviors against both the metabolic and the well-being outcomes simultaneously, within a single community-dwelling older-adult population frame.；Four objectives give the work its order: to chart which exposures have been studied against which outcomes; to summarize the reported associations with the cardiometabolic markers as well as with the domains of well-being; to place the assessment and the follow-up methods of the community studies alongside one another; and to name the gaps, then turn the findings toward the design of future work and the refinement of the guidelines. presents the 24-hour movement composition as a closed daily budget of 1,440 minutes, partitioned among sleep, sedentary time, light activity and moderate-to-vigorous activity.
方法
We conducted a scoping review following the methodological framework of Arksey and O'Malley (), as refined by Levac et al.；In accordance with the journal's requirements, the eligibility framework was additionally structured according to the Population, Intervention/Exposure, Comparator, Outcomes, and Study design (PICOS) components.；We included primary studies with observational or interventional designs published in English.；We excluded samples recruited on the basis of a defining metabolic or other disease at baseline, samples below the age threshold, records without a relevant exposure or outcome, and reviews, protocols, and conference abstracts.
核心结论
Twenty-seven studies were included in the charted evidence base; 39 reports did not meet the charting criteria and 16 were retained solely as clinical or contextual references for the Discussion.；Sedentary behavior was defined as the waking time spent sitting or reclining at a very low cost in energy, at or below 1.5 metabolic equivalents of task (METs); it was distinguished from mere inactivity, since a person could satisfy an activity target and still sit for long unbroken stretches.；Because the four components summed to the whole day, the studies interpreted them together, asking what became of the markers when 30 min were reallocated from the sedentary share to the active or the sleeping share. ‖ 结论：Evidence relating to well-being was broader and more consistent, although it was dominated by cognition; mood, physical function, and quality of life were assessed too infrequently to support conclusions about well-being as a whole.
局限
The direction of evidence similarly favored well-being: cognitive findings were broadly consistent across cross-sectional, longitudinal, and interventional designs, while metabolic responses were more selective, with some markers changing and others remaining unchanged.；Measurement approaches ranged from wearable devices to self-report, and study duration varied from acute laboratory assessments to decade-long follow-up.；Two findings were particularly informative across domains: in one cross-sectional study of short-sleeping older adults, the cognitive dose-response appeared to plateau at approximately 800–960 MET-min/week (), a threshold that awaits replication in other samples; sleep effic
