OBJECTIVE
This article investigates social inequality in onset of mobility disability and in measures of social relations and whether social relations mediated the effect of socioeconomic status on mobility.
METHOD
A total of 2,825 nondisabled older men and women, enrolled in the Danish Intervention Study on Preventive Home Visits, constituted the study population. Data were obtained by mailed questionnaires in 1998-1999 and 2001-2002 and by merging analyses to registers at Statistics Denmark.
RESULTS
There was a social gradient in onset of mobility disability, with odds ratio of 1.11 (1.07-1.15) per step down the deciles of financial assets and in cohabitation status, social participation, and network diversity. Social relations did not mediate the effect of financial assets on onset of mobility disability.
DISCUSSION
The negative effects of low financial assets and poor social relations on mobility appear to be independent. More longitudinal studies on possible mediators of the social gradient in mobility among older people are needed.
目的
本文旨在研究流动性残疾的发生以及社会关系衡量标准方面的社会不平等现象，以及社会关系是否在社会经济地位对流动性的影响中起中介作用。
方法
丹麦预防家庭探访干预研究共纳入了 2825 名无残疾的老年男性和女性，作为研究对象。数据于 1998-1999 年和 2001-2002 年通过邮寄问卷获得，并通过与丹麦统计局的注册信息进行合并分析。
结果
流动性残疾的发生呈现出社会阶层梯度，按金融资产十分位数每降低一个等级，其优势比为 1.11（1.07-1.15），在同居状况、社会参与度和网络多样性方面也是如此。社会关系并不能调节金融资产对流动性残疾发生的影响。
讨论
低金融资产和较差社会关系对流动性的负面影响似乎是独立的。需要更多的纵向研究来探讨老年人流动性社会梯度的可能中介因素。
