| 目的 分析≥50岁人群中每日静坐时间与衰弱发生的关系。方法 利用WHO全球老龄化与成人健康研究中国项目第一轮基线调查，采用两水平（个体层面和社区层面）logistic回归模型按城乡进行分层分析每日静坐时间与衰弱的关系，并采用限制性立方样条曲线分析两者之间的剂量-反应关系。结果 共纳入13 175名≥50岁中老年人进行分析。城市（OR=1.22，95% CI：1.17～1.27）及农村（OR=1.11，95% CI：1.05 ～1.18）地区人群每日静坐时间与衰弱发生均显著相关。限制性立方样条曲线显示，每日静坐时间与衰弱发生存在近似线性剂量-反应关系。结论 每日静坐时间与衰弱发生显著相关，并呈近似线性关系。 |

| Objective To investigate the association between daily sedentary time and frailty among people aged 50 years and over. Methods Cross-sectional data was collected from the first wave of World Health Organization Study on global AGEing and adult health in China. A two-level (individual level and community level) logistic model was performed to identify the association between daily sedentary time and frailty. The dose-response relationship between them was analyzed by restrictive cubic spline curve. Results A total of 13 175 individuals aged 50 years and over were included for analysis. A positive association between daily sedentary time and frailty was noticed, both in urban (OR=1.22, 95%CI:1.17-1.27) or rural areas (OR=1.11, 95%CI:1.05-1.18) under study. The dose-response curve showed that daily sedentary time and frailty might present an approximate linear relationship. Conclusion Results from this study showed significant association exsited between daily sedentary time and frailty, approximately with a linear dose-response relationship. |
