By 2050, 20% of the world's population will be over age 65 years, with projections that 80% older adults living in low- to middle-income countries. Physical inactivity and sedentary time are particularly high adults, presenting unique public health challenges. In this article, we first review evidence points multiple beneficial outcomes active aging, including better physical function, cognitive mental health, social sleep, suggest need shift research focus from chronic disease more relevantoutcomes affect independence quality life.

A systematic review of compositional data analysis studies examining associations between sleep, sedentary behaviour, and physical activity with health outcomes in adults

This systematic review determined if the composition of time spent in movement behaviours (i.e., sleep, sedentary behaviour (SED), light physical activity, and moderate-to-vigorous activity (MVPA)) is associated with health adults. Five electronic databases were searched August 2019. Studies eligible for inclusion they peer-reviewed, examined community-dwelling adults, used compositional data analysis to examine associations between outcomes.

Sleep regularity is a stronger predictor of mortality risk than sleep duration: A prospective cohort study

Abstract Abnormally short and long sleep are associated with premature mortality, achieving optimal duration has been the focus of health guidelines. Emerging research demonstrates that regularity, day-to-day consistency sleep–wake timing, can be a stronger predictor for some outcomes than duration. The role regularity in however, not investigated large cohort objective data. We therefore aimed to compare how predicted risk all-cause cause-specific mortality. calculated Sleep Regularity Index (SRI) scores from > 10 million hours accelerometer data 60 977 UK Biobank participants (62.8 ± 7.8 years, 55.0% female, median[IQR] SRI: 81.0[73.8–86.3]). Mortality was reported up years after recording 1859 (4.84 deaths per 1000 person-years, mean (±SD) follow-up 6.30 0.83 years). Higher 20%–48% lower mortality (p < .001 p = 0.004), 16%–39% cancer 0.001 0.017), 22%–57% cardiometabolic 0.048), across top four SRI quintiles compared least regular quintile.

Chrono-Nutrition: Circadian Rhythm and Personalized Nutrition

International Journal of Molecular Sciences, Journal Year: 2023, Volume and Issue: 24(3), P. 2571 - 2571

Published: Jan. 29, 2023

The human circadian system has a period of approximately 24 h and studies on the consequences “chornodisruption” have greatly expanded. Lifestyle environmental factors modern societies (i.e., artificial lighting, jetlag, shift work, around-the-clock access to energy-dense food) can induce disruptions thereby adversely affect individual health. Growing evidence demonstrates complex reciprocal relationship between metabolism system, in which perturbations one other one. From nutritional genomics perspective, genetic variants clock genes both influence metabolic health modify response diet. Moreover, an interplay rhythm, gut microbiome, epigenome been demonstrated, with diet turn able modulate this link suggesting remarkable plasticity underlying mechanisms. In view, study impact timing eating by matching elements from research chrono-biology, that is, chrono-nutrition, could significant implications for personalized nutrition terms reducing prevalence burden chronic diseases.
