【摘要】 目的 了解浙江省北部≥60岁老年人肌少症患病情况与社会支持间的相关性。方法 基于2014年浙江省疾病预防控制中心开展的浙江省老年人健康队列，在浙江省12个县（区）点中选取北部4个县（区），抽取≥60岁的老年人为调查对象开展肌少症相关调查，采用问卷收集对象人口学特征以及生活行为方式等信息，结合χ~2检验与logistic回归模型，分析与肌少症患病情况相关的社会支持因素。结果 本研究有效调查4 168人，其中男性1 891人，女性2 277人，患肌少症613例，患病率14.71%。多因素logistic回归显示，独居生活是肌少症的危险因素（模型1:OR=1.61, 95%CI:1.31～2.00；模型2:OR=1.35,95%CI:1.00～1.83；模型3:OR=1.39, 95%CI:1.02～1.88），经常保持与10个以上亲戚朋友走动（模型1:OR=0.40, 95%CI:0.28～0.58；模型2:OR=0.46, 95%CI:0.30～0.71；模型3:OR=0.47,95%CI:0.30～0.73）是患肌少症的保护因素，且以上2个因素在≥60岁的老年女性中作用尤为显著。结论 独居生活、经常保持与亲戚朋友间的走动是肌少症的影响因素，良好的社会支持能够降低肌少症的患病风险，建议老年人群，尤其是独自居住的老年女性，多与邻居沟通，并加强与亲戚朋友间的走动。更多还原

【Abstract】 Objective To study the association between the prevalence of sarcopenia and social support in the elderly aged 60 and above in Northern Zhejiang Province. Methods Based on the Zhejiang Elderly Health Cohort conducted by the Zhejiang Provincial Center for Disease Control and Prevention in 2014,four countries in northern Zhejiang were selected as survey sites, and individuals aged 60 years or above were surveyed for sarcopenia. The information demographic characteristics and lifestyle information were collected by questionnaire. The χ~2 test and logistic regression models were employed to analyze social support factors related to sarcopenia. Results A total of 4 168 individuals were surveyed, including 1 891males and 2 277 females, with 613 cases of sarcopenia and a prevalence of 14. 71%. According to the results of multivariate logistic regression analysis, living alone was the risk factor for sarcopenia(Model Ⅰ : OR=1. 61, 95%CI: 1. 31-2. 00; Model Ⅱ : OR=1. 35, 95%CI: 1. 00-1. 83; Model Ⅲ : OR=1. 39,95%CI: 1. 02-1. 88), while visiting more than ten relatives or friends(Model Ⅰ : OR=0. 40, 95%CI:0. 28-0. 58; Model Ⅱ : OR=0. 46, 95%CI: 0. 30-0. 71; Model Ⅲ : OR=0. 47, 95%CI: 0. 30-0. 73) was the protective factor for sarcopenia. The effect of these influencing factors was more significant in the female group. Conclusions Living alone and keeping contact with relatives or friends were the factors for sarcopenia. Thus, available social support can decrease the risk of sarcopenia. It is indicated that the elderly, particularly elderly women, are advised to communicate a lot with their neighbors and keep in touch with relatives or friends as more as possible.更多还原
