to investigate if the increased risk of disability onset among older people who live alone could possibly be moderated by either high social participation or by being satisfied with the social relations.
logistic regression models were tested using two waves in a study population of 2,697 non-disabled older men and women from The Danish Longitudinal Study on Preventive Home Visits.
living alone and low social participation were significant risk factors for later male disability onset. Not being satisfied with the social relations was significantly associated with onset of disability for both genders. Among men who lived alone low social participation was a significant predictor of disability onset [odds ratio, OR = 2.30 (1.00-5.29)]; for cohabiting men social participation was not associated with disability onset, [adjusted OR = 0.91 (0.49-1.71)]. Similar results were present concerning satisfaction with the social relations among men. There was no significant interaction for women.
the study suggests that men who live alone can possibly alleviate their risk of disability onset by being socially active and by having access to satisfactory social relations. Women do not seem to benefit as much from cohabitation as men, although women who live alone and who are not satisfied with their social relations also constitute a significant risk category.
探讨独居老年人残疾发病风险增加的原因，这种风险是否可以通过高社交参与度或对社交关系满意来缓解。
利用丹麦预防性家庭访问纵向研究中 2697 名非残疾老年男女的两波数据，测试了逻辑回归模型。
独居和低社交参与是男性日后残疾发病的显著危险因素。两性对社交关系不满意均与残疾发病显著相关。对于独居男性，低社交参与是残疾发病的显著预测因素[优势比（OR）=2.30（1.00-5.29）]；对于同居男性，社交参与与残疾发病无关[调整后的 OR=0.91（0.49-1.71）]。男性对社交关系的满意度也存在类似结果。女性没有显著的交互作用。
研究表明，独居男性可以通过积极参与社交活动和获得满意的社交关系来降低残疾发病的风险。女性似乎不能像男性那样从同居中受益，尽管独居且对社交关系不满意的女性也构成了一个显著的风险类别。
