“…Three of the four articles included in this review reported the assessment of total sedentary time in minutes per day [3,33,34], the other reported SB in hours/day [21]. Three studies evaluated SB objectively using accelerometer devices identified by activity<100\ counts per minute (cpm) [21,32,33], while one study evaluated the association between ST and mobility limitation using only one question [34]. In contrast, the physical disability in the studies selected was measured indirectly (3 self-reports and 1 questionnaire), which was based on the information provided by individuals.…”

“…All studies selected were adjusted for multiple potential confounding variables including age and gender [3,21,34] which allowed us to explore in our analysis the relationship of effect size with age and sex. Overall, all studies also included the assessment of chronic conditions and body mass index, as covariates.…”

“…Table 1 presents characteristics of the four selected studies. Two studies were carried out in the United States [21,32], one in Portugal [33] and one in Taiwan [34]. Furthermore, a majority of these studies were conducted between 2014 and 2017, and the sample size varied from 140 to 2,286.…”

This systematic review and meta-analysis examined the relationship between sedentary behavior (SB) and disability in older adults. A search was conducted using PubMed, Web of Science, and Sport Discus databases to identify eligible studies. Of the 405 studies identified, only 4 studies met our predefined criteria to be included in this metaanalysis. In these studies, participants who reported having a disability had higher levels of SB (effect size: 0.38, 95% IC: 0.14-0.62, p<0. 002) than those without disability. Older adults with disabilities seem to engage in higher levels of SB (mean 5.8 to 10.3 hours/day) when compared with older adults without disability (mean of 4.6 to 9.7 hours/ day). The findings of this review and meta-analysis suggest that there is an association between SB and disability. Our findings, however, are limited to cross-sectional studies and thus direction of this relationship is not clear based on studies to date.

Osteoporosis (low bone strength) and sarcopenia (low muscle mass, strength and/or impaired function) often co-exist (hence the term 'sarco-osteoporosis') and have similar health consequences with regard to disability, falls, frailty and fractures. Exercise and adequate nutrition, particularly with regard to vitamin D, calcium and protein, are key lifestyle approaches that can simultaneously optimize bone, muscle and functional outcomes in older people, if they are individually tailored and appropriately prescribed in terms of the type and dose. Not all forms of exercise are equally effective for optimizing musculoskeletal health. Regular walking alone has little or no effect on bone or muscle. Traditional progressive resistance training (PRT) is effective for improving muscle mass, size and strength, but it has mixed effects on muscle function and falls which may be due to the common prescription of slow and controlled movement patterns. At present, targeted multi-modal programs incorporating traditional and high-velocity PRT, weight-bearing impact exercises and challenging balance/mobility activities appear to be most effective for optimizing musculoskeletal health and function. Reducing and breaking up sitting time may also help attenuate muscle loss. There is also evidence to support an interaction between exercise and various nutritional factors, particularly protein and some multi-nutrient supplements, on muscle and bone health in the elderly. This review summary provides an overview of the latest evidence with regard to the optimal type and dose of exercise and the role of various nutritional factors for preventing bone and muscle loss and improving functional capacity in older people.

Self-reported Sitting Time is Associated With Decreased Mobility in Older Adults

Abstract: Sitting time in older adults can be reliably measured with a reported measure (a recall strategy) over a 1-week interval. Older adults who spend more time sitting are more likely to experience mobility limitation.
