Aims
To examine the relationship between leisure‐time physical activity, sitting time and prefrailty in community‐dwelling older adults.
Design
Cross‐sectional study.
Methods
Between February and July 2019, 539 individuals over age 60 were recruited in northern Taiwan. Demographic, medical history, physical activity and frailty data were analysed using descriptive statistics, chi‐square tests and logistic regression.
Results
The prevalence of prefrailty was 24.4%; 33.2% had regular leisure‐time physical activity, and 14.7% reported >6 hrs daily sitting time. Compared with individuals having regular leisure‐time physical activity and shorter sitting times (daily average ≤6 hrs), those having no regular leisure‐time physical activity and also shorter sitting times (adjusted OR, 1.80; 95% CI, 1.12, 2.92), or those also having regular leisure‐time physical activity but longer sitting times (adjusted OR, 4.42; 95% CI, 2.22, 8.79) had an increased prefrailty risk.
Conclusions
Having no regular leisure‐time physical activity or longer sitting times is associated with a higher risk of prefrailty. For sedentary older adults to prevent prefrailty, they can become more active, sit less or better yet, commit to both.
The aims of this study were to investigate the prevalence of sleep disorders in patients with end-stage renal disease (ESRD), and to assess the effect of dialysis schedule on sleep quality and the presence of daytime symptoms. We prospectively selected 150 long-term hemodialysis (HD) patients in three groups (morning, afternoon, and evening dialysis) and gave them a sleep questionnaire, the Epworth sleepiness scale and the Pittsburgh sleep quality index. Snoring was the most common complaint (56%), followed by insomnia (38%) and restless legs syndrome (22.7%). The evening dialysis group experienced more sleep time in bed (P = 0.02), required less hypnotic medication (P = 0.049), had fewer daytime symptoms (P < 0.01), and experienced less daytime sleepiness (P = 0.034). Our study confirms the high prevalence of sleep disorders in ESRD patients, and indicates a beneficial effect of evening HD on sleep quality and reduction of daytime symptoms.
The purpose of this study was to examine the effects of a long-term community-based lifestyle intervention on the biochemical indicators and prevalence of metabolic syndrome among elderly adults. This was a randomized controlled trial in northern Taiwan from August 2013 to February 2015. Sixty-nine elderly adults participated in this study. There were three measurements. The experimental group participated in exercise and diet interventions. The control group participated in the exercise intervention. Repeated measurement and ANCOVA were performed to evaluate the effectiveness. After 18 months, body weight (1.06 kg), body mass index (1.21 kg/m), waist circumference (3.32 cm), blood pressure, and prevalence (30.4%) of metabolic syndrome were significantly reduced in all subjects. There were significant differences in waist circumference and high-density lipoprotein cholesterol between the two groups. This intervention can lower the indicators and prevalence of metabolic syndrome. Exercise and diet interventions could promote further metabolic changes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
