背景资料：虽然在概念上被认为是残疾和社会孤立的一个危险因素，但很少有关于居家状态的流行病学研究。这项研究旨在探讨是否是居家是残疾的一个危险因素，以及是否低水平的社会接触会增加老年人的风险。研究方法：2000年10月，向2 932名社区居住的老年人（65岁及以上）发放了一份关于人口特征的问卷。有2459个回答，2180个回答者独立进行日常生活活动。其中，2046人接受了随访，直至2003年3月。这2046人成为我们分析的对象。在随访期结束时，对2046例受试者进行了残疾评估。结果如下：总体而言，7.5%的受试者在基线时足不出户，其中约一半能够在无人协助的情况下离开家，很少这样做，但有社会接触。在随访期结束时，12.7%的受试者被确定为残疾。残疾的发生率是较高的，在居家的年龄小于85岁的受试者比非居家的，但没有显着差异，年龄超过85岁的受试者。残疾水平在所有居家受试者组高于非居家受试者。没有社会接触的受试者比其他人表现出更高的残疾发生率，尽管差异在统计学上并不显著。总结：对于独立生活的65-85岁社区居民来说，足不出户似乎是残疾的一个风险因素，但事实证明，社会接触水平低并不是导致居家老年人残疾的另一个风险因素。
Background: Although being housebound is acknowledged conceptually as a risk factor for disability and social isolation, there has been little epidemiologic research on housebound status. This study aimed to explore whether being housebound is a risk factor for disability and whether a low level of social contact increases that risk in elderly persons. Methods: A questionnaire pertaining to demographic characteristics was administered to 2932 community-dwelling elderly persons (aged 65 years and older) in October 2000. There were 2459 responses, and 2180 respondents were independently performing activities of daily living. Of these, 2046 were followed up until March 2003. These 2046 people became the subjects of our analysis. At the end of the follow-up period, the 2046 subjects were assessed for disability. Results: Overall, 7.5% of the subjects were housebound at baseline, and about half of these were able to leave the house unassisted, seldom did so but had social contact. At the end of the follow-up period, 12.7% of subjects were identified as disabled. The incidence of disability was higher in housebound than in non-housebound subjects aged less than 85 years but did not differ significantly among subjects aged more than 85 years. Levels of disability were higher in all housebound subjects groups than in non-housebound subjects. Subjects without social contact exhibited a higher incidence of disability than others, although the difference was not statistically significant. Conclusion: Being housebound appears to be a risk factor for disability in community-dwelling individuals aged 65-85 years who are living independently, but a low level of social contact was not proved to be an additional risk factor for disability among housebound elderly persons.
