OBJECTIVE
To investigate the effect of cohabitation status in older men and women on (a) onset of disability at 3- and 4.5-year follow-up and (b) changes in functional ability between 3- and 4.5-year follow-up, and to analyze whether this effect was mediated by social participation.
METHOD
A total of 2,533 nondisabled older men and women enrolled in the Danish Intervention Study on Preventive Home Visits constituted the study population. Data were collected by mailed questionnaires in 1998-1999, 2000, 2001-2002, and 2003.
RESULTS
Living alone significantly increased the risk of onset of disability (T3 OR = 1.60[1.06-2.43], T4 OR = 1.74[1.22-2.47]) and the risk of sustained poor functional ability (OR = 2.35[1.44-3.84]) among men, but not among single-living women. Social participation mediated only a small part of the effect of cohabitation status on functional ability.
DISCUSSION
Our results underline the importance of cohabitation/marriage for maintaining a high functional ability among older men.
目的
调查老年男性和女性的同居状况对以下方面的影响：（a）在3年和4.5年随访时残疾的发生情况；（b）3年和4.5年随访期间功能能力的变化，并分析这种影响是否通过社会参与介导。
方法
丹麦预防性家访干预研究中纳入的2533名无残疾的老年男性和女性构成了研究人群。数据通过邮寄问卷于1998 - 1999年、2000年、2001 - 2002年和2003年收集。
结果
独居显著增加了男性残疾发生的风险（T3时OR = 1.60[1.06 - 2.43]，T4时OR = 1.74[1.22 - 2.47]）以及持续功能能力差的风险（OR = 2.35[1.44 - 3.84]），但在独居女性中并非如此。社会参与仅介导了同居状况对功能能力影响的一小部分。
讨论
我们的结果强调了同居/婚姻对于维持老年男性高功能能力的重要性。
