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.
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.
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).
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.
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.
众所周知，包括身体活动（PA）、久坐行为（SB）和睡眠在内的24小时运动行为是影响老年人健康的关键因素。加拿大老年人24小时运动指南于2020年发布，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，关于指南遵循情况的患病率、相关因素及其与健康相关结局的关联的研究有限，尤其是在中国老年人中。
本研究旨在调查中国老年人遵循24小时运动指南的患病率及其相关因素。此外，本研究旨在探讨遵循指南与老年人身心健康结局之间的关联。
采用分层整群随机抽样方法，于2020年7月25日至11月19日从中国湖北省最新的省级健康监测中招募了4562名老年人（平均年龄67.68岁，标准差5.03岁；女性比例：2544/4562，55.8%）。测量指标包括人口统计学特征、运动行为（PA、SB和睡眠）、体重指数（BMI）、腰围、腰臀比（WHR）、体脂百分比（PBF）、收缩压和舒张压、身体素质、抑郁症状和孤独感。使用SPSS 28.0（IBM公司）采用广义线性混合模型来检验变量之间的关联。
只有1.8%（83/4562）的参与者符合所有三项运动指南，而分别有32.1%（1466/4562）、3.4%（155/4562）和66.4%（3031/4562）的参与者符合PA、SB和睡眠的个体行为指南。年龄较大、女性以及生活在经济水平较低城市的参与者不太可能符合所有三项运动指南。遵循个体或综合运动指南与更好的身体素质以及更低的BMI、腰围、WHR、PBF、抑郁症状和孤独感相关，但SB+睡眠指南与孤独感的关系除外。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。
这是第一项关于中国老年人遵循24小时运动指南的患病率、相关因素及其与身心健康结局关联的研究。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求。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。
