目的：本研究调查是否孤独或社会隔离与功能残疾的发病超过4年的中国老年人population.Setting和Subjects：本研究使用的数据来自中国健康和退休纵向研究（CHARLS）。功能状态通过日常生活活动（ADL）和工具性日常生活活动（IADL）进行评估。对两波（2011年和2015年）的数据进行分析，仅限于50岁及以上的受访者，基线时无功能性残疾[n = 5，154，平均年龄（SD）= 60.72（7.51）;男性，52.3%]。方法：在基线时测量社会隔离、孤独和协变量。4年后随访新发ADL和IADL残疾。我们按性别对样本进行分层，然后使用二元逻辑回归来评估基线隔离，孤独和新发ADL和IADL残疾之间的关联。对于女性，基线社会隔离与新发ADL显著相关（OR = 1.18，95%CI = 1.071.30）和IADL（OR= 1.11，95%CI = 1.01-1.21）残疾;孤独感与ADL或IADL残疾之间无显著相关性。这项纵向研究发现，在中国女性（但不是男性）中，4年以上的功能障碍与社会孤立而不是孤独显着相关。这些发现扩展了我们对非西方人群中社会关系和功能状态之间关联的认识。
Objective: This study investigated whether loneliness or social isolation is associated with the onset of functional disability over 4 years among Chinese older populations.Setting and Subjects: This study used data from the China Health and Retirement Longitudinal Study (CHARLS). Functional status was assessed by activities of daily living (ADL) and instrumental activities of daily living (IADL). Analyses were conducted with data from two waves (2011 and 2015) and were restricted to those respondents aged 50 and older and free of functional disability at baseline [n = 5,154, mean age (SD) = 60.72 (7.51); male, 52.3%].Method: Social isolation, loneliness and covariates were measured at baseline. Follow-up measures of new-onset ADL and IADL disability were obtained 4 years later. We stratified the sample by gender, and then used binary logistic regressions to evaluate the associations between baseline isolation, loneliness and new-onset ADL and IADL disability.Results: For women, baseline social isolation was significantly associated with new-onset ADL (OR = 1.18, 95% CI = 1.071.30) and IADL (OR= 1.11, 95% CI = 1.01-1.21) disability; no significant association between loneliness and ADL or IADL disability was found. For men, neither social isolation nor loneliness was found to be significantly associated with ADL or IADL disability.Conclusion: This longitudinal study found that social isolation, rather than loneliness, was significantly associated with functional disability over 4 years among women (but not men) in China. These findings expand our knowledge about the association between social relationships and functional status among non-Western populations.
