老年人主客观社会隔离与其生理健康相互影响关系的探究——基于CLHLS生化数据的验证

The Reciprocal Associations Between Perceived and Objective Social Isolation and Physical Health of Older People:An Empirical Study Base on CLHLS Biomarker Datasets

基于CLHLS生化数据,本文以客观条件与主观感知二种维度考察了社会隔离与老年人代谢综合征(MetS)、日常生活活动能力(ADL)与工具性日常生活活动能力(IADL)的相互影响关系。通过交叉滞后模型的分析,本文的主要研究结果表明:其一,客观条件社会隔离与老年人生理健康之间的相互影响关系,实际上可能是由年龄、性别等人口学特征因素造成的。其二,主观感知社会隔离对老年人生理健康有显著影响,其影响机制包括对生理代谢功能(MetS)和生活自理能力(IADL)的改变,且不受人口学特征因素影响。其三,日常生活能力(ADL)反过来对于老年人的主观感知社会隔离有显著加强。因此,我们认为主观社会隔离是解释社会隔离与老年人生理健康之间的相互影响关系的关键。对于老年人主观感知的社会隔离应当通过多种途径进行干预加以缓解,并且,对于有日常生活活动能力障碍老人,尤其应当注重为其提供有效的生活服务以及心理慰藉以缓解其孤独和无助感。

Based on CLHLS bio-marker data, this study investigates the reciprocal associations between social isolation measured objectively and perceptively and physical health status including metabolic syndrome(Met S), daily life activity ability(ADL) and instrumental daily life activity ability(IADL) of the older people by cross-lagged model. The findings show: Firstly, the association between objective social isolation and physical health of the elderly may actually be caused by demographic characteristics such as age and gender;Secondly, perceived social isolation has a significant impact on physical health of the older people through the changes in physiological metabolism(Met S) and independent living ability(IADL) regardless of demographic characteristics;Thirdly, daily living ability(ADL), in turn, significantly enhances the subjective perception of social isolation among the elderly. Therefore, we believe that subjective social isolation is vital to explain the reciprocal associations between social isolation and the physical health of the older people and it is necessary to provide various services to alleviate their perceived social isolation.
