背景:众所周知,24小时运动行为,包括体力活动(PA),久坐行为(SB),和睡眠,是影响老年人健康的关键因素。加拿大于2020年发布了针对老年人的24小时运动指南,强调了这三种运动行为在促进老年人健康方面的综合作用。然而,关于指南依从性的患病率和相关性及其与健康相关结果的关联的研究有限,尤其是中国老年人。
目的:本研究旨在调查中国老年人参加24小时运动指南的患病率和相关性。此外,本研究旨在研究指南依从性与老年人身体和心理健康结局的相关性.
方法:使用分层整群随机抽样方法,共有4562名老年人(平均年龄67.68岁,SD5.03岁;女性比例:2544/4562,55.8%)从2020年7月25日至11月19日湖北省最新的省级健康监测中招募。措施包括人口统计,运动行为(PA,SB,和睡眠),BMI,腰围,腰臀比(WHR),体脂百分比(PBF),收缩压和舒张压,身体健康,抑郁症状,和孤独。使用SPSS28.0(IBMCorp)采用广义线性混合模型来检查变量之间的关联。
结果:只有1.8%(83/4562)的参与者符合所有3个运动指南,而32.1%(1466/4562),3.4%(155/4562),66.4%(3031/4562)符合PA的个人行为指南,SB,和睡眠,分别。年龄较大的参与者,是女性,生活在经济水平较低的城市,不太可能满足所有3个运动准则。坚持个人或联合运动指南与更高的身体素质和更低的BMI值相关,腰围,WHR,PBF,抑郁症状,和孤独,除了SB+睡眠指南与孤独感的关系。此外,仅符合SB指南或同时符合PA和SB指南与较低的收缩压相关.
结论:这是第一项调查中国老年人对24小时运动指南在患病率方面的依从性的研究,相关性,以及与身心健康结果的关联。研究结果强调了在中国老年人中促进健康运动行为的迫切需要。未来改善老年人身心健康的干预措施应包括增强他们的整体运动行为,并应考虑人口统计学差异。
BACKGROUND: It is known that 24-hour movement behaviors, including physical activity (PA), sedentary behavior (SB), and sleep, are crucial components affecting older adults\' health. Canadian 24-hour movement guidelines for older adults were launched in 2020, emphasizing the combined role of these 3 movement behaviors in promoting older adults\' health. However, research on the prevalence and correlates of guideline adherence and its associations with health-related outcomes is limited, especially among Chinese older adults.
OBJECTIVE: This study aimed to investigate the prevalence and correlates of meeting 24-hour movement guidelines among Chinese older adults. Furthermore, this study aimed to examine the associations of guideline adherence with older adults\' physical and mental health outcomes.
METHODS: Using a stratified cluster random sampling approach, a total of 4562 older adults (mean age 67.68 years, SD 5.03 years; female proportion: 2544/4562, 55.8%) were recruited from the latest provincial health surveillance of Hubei
China from July 25 to November 19, 2020. Measures included demographics, movement behaviors (PA, SB, and sleep), BMI, waist circumference, waist-hip ratio (WHR), percentage body fat (PBF), systolic and diastolic blood pressure, physical fitness, depressive symptoms, and loneliness. Generalized linear mixed models were employed to examine the associations between variables using SPSS 28.0 (IBM Corp).
RESULTS: Only 1.8% (83/4562) of participants met all 3 movement guidelines, while 32.1% (1466/4562), 3.4% (155/4562), and 66.4% (3031/4562) met the individual behavioral guidelines for PA, SB, and sleep, respectively. Participants who were older, were female, and lived in municipalities with lower economic levels were less likely to meet all 3 movement guidelines. Adhering to individual or combined movement guidelines was associated with greater physical fitness and lower values of BMI, waist circumference, WHR, PBF, depressive symptoms, and loneliness, with the exception of the relationship of SB+sleep guidelines with loneliness. Furthermore, only meeting SB guidelines or meeting both PA and SB guidelines was associated with lower systolic blood pressure.
CONCLUSIONS: This is the first study to investigate adherence to 24-hour movement guidelines among Chinese older adults with regard to prevalence, correlates, and associations with physical and mental health outcomes. The findings emphasize the urgent need for promoting healthy movement behaviors among Chinese older adults. Future interventions to improve older adults\' physical and mental health should involve enhancing their overall movement behaviors and should consider demographic differences.
