摘要
背景:本研究旨在通过相关研究的荟萃分析,探讨基于传感器的老年人日常身体活动模式评估与身体健康之间的关系。方法:系统检索6个数据库(PubMed, CINAHL由EBSCOhost, Web of Science, PsycInfo由ProQuest, Embase和Scopus),从成立到2025年1月18日。还进行了参考文献列表和谷歌Scholar的人工搜索,利用预定义的关键词识别具有双变量关联分析的观察性研究。采用乔安娜布里格斯研究所横断面研究关键评估清单评估研究质量。关联分析根据日常活动(久坐、轻度、中度至剧烈)和身体健康(如握力、膝关节肌肉力量、腿部力量、步行耐力、活动功能和步态速度)的特征进一步分类。结果:13项横断面研究被纳入meta分析。平均而言,老年人每天有78%的时间是久坐不动的,15%的时间是低强度活动,7%的时间是中高强度活动。久坐行为与较低的身体健康有关(公式:见文),而中等到剧烈的活动与较好的身体健康有关(公式:见文);低强度活动与更好的活动功能和步态速度只有微弱的选择性关联([公式:见文]至0.26)。结论:这篇综述表明,虽然老年人每天大部分时间都坐着不动,但中等到高强度和低强度的体育活动都与更好的身体健康有关。促进低强度活动可能是一个实用的策略,以支持流动性和独立性,特别是对那些无法达到更高的活动准则。然而,建议仍应保持谨慎,因为支持低强度体力活动与身体健康之间联系的证据目前还很薄弱。普洛斯彼罗注册:本系统评价的方案在普洛斯彼罗注册(注册号:CRD42023471302)。
The association between sensor-based assessments of daily physical activity patterns and physical fitness in older adults: a systematic review and meta-analysis.
Background: This study aimed to investigate the association between sensor-based assessment of daily physical activity patterns and physical fitness among older adults by meta-analyses of relevant studies.
Methods: A systematic search was conducted across six databases (PubMed, CINAHL by EBSCOhost, Web of Science, PsycInfo by ProQuest, Embase, and Scopus) from inception until January 18, 2025. Manual searches of reference lists and Google Scholar were also performed, utilizing predefined keywords to identify observational studies with bivariate association analyses. Joanna Briggs Institute Critical Appraisal Checklist for Cross-Sectional Studies was employed to assess study quality. The association analyses were further categorized based on the characteristics of daily activity (sedentary, light, moderate-to-vigorous) and physical fitness (e.g., grip strength, knee muscle strength, leg power, walking endurance, mobility function, and gait speed).
Results: Thirteen cross-sectional studies were included in the meta-analyses. On average, older adults spent 78% of their day sedentary, 15% in light-intensity activity, and 7% in moderate-to-vigorous activity. Sedentary behavior was linked to lower physical fitness ([Formula: see text] to [Formula: see text]), while moderate-to-vigorous activity was linked to better fitness ([Formula: see text] to 0.43); light-intensity activity showed only weak and selective associations with better mobility function and gait speed ([Formula: see text] to 0.26).
Conclusion: This review shows that while older adults spend much of their day sedentary, both moderate-to-vigorous and light-intensity physical activity are linked to better physical fitness. Promoting light-intensity activities may be a practical strategy to support mobility and independence, especially for those unable to meet higher activity guidelines. However, recommendations should remain cautious, as the evidence supporting an association between light-intensity physical activity and physical fitness is currently weak.

期刊介绍:
European Review of Aging and Physical Activity (EURAPA) disseminates research on the biomedical and behavioural aspects of physical activity and aging. The main issues addressed by EURAPA are the impact of physical activity or exercise on cognitive, physical, and psycho-social functioning of older people, physical activity patterns in advanced age, and the relationship between physical activity and health.
