目标.这项研究是为了确定是否有活力和虚弱的老年人谁识别环境危害在他们的家园有增加的风险下降。在266名女性和59名男性社区居民志愿者中进行了为期1年的前瞻性研究，这些志愿者年龄在60至93岁之间，在过去一年中至少跌倒过一次。家庭安全和脆弱的综合措施，采用主成分分析。参与者被分为精力充沛组和虚弱组，并比较两组之间基线家庭安全措施与随访一年内在家跌倒的福尔斯之间的关联。结果。在随访期间，虚弱个体跌倒的可能性是强壮个体的两倍多（率比[RR] = 2.24; 95%置信区间[C] = 1.54，3.27）。在整个研究组中，福尔斯与家庭危险的存在没有很强的相关性。然而，与生活在较少家庭危险中的精力充沛的老年人相比，生活在更多家庭危险中的精力充沛的老年人更容易摔倒。在精力充沛的老年人中，福尔斯跌倒的风险增加仅限于存在家庭危险的福尔斯。相比之下，生活在更多的家庭危险与体弱老年人福尔斯的可能性增加无关。虽然体弱的老年人的总体跌倒率较高，但在跌倒预防项目中不应忽视精力充沛的老年人。
Objectives. This study was undertaken to determine whether vigorous and frail older people who identify environmental hazards in their homes have an increased risk for falls.Methods. A 1-year prospective study was conducted among 266 female and 59 male community-dwelling volunteers aged 60 to 93 years who had fallen at least once during the previous year. Composite measures of home safety and of frailty were derived using principal components analysis. Participants were divided into vigorous and frail groups, and associations between baseline home safety measures and falls at home over the follow-up year were compared between the two groups.Results. Frail individuals were more than twice as likely as vigorous individuals to fall during follow-up (rate ratio [RR] = 2.24; 95% confidence interval [C] = 1.54, 3.27). In the study group as a whole, falls were not strongly associated with the presence of home hazards. However, when compared with vigorous older persons living with fewer home hazards, vigorous older persons living with more home hazards were more likely to fall. The increased risk for falls among vigorous elderly was limited to falls where home hazards were present. By contrast, living with more home hazards was not associated with increased likelihood of falls among frail older persons.Conclusions. While frail older persons experience higher overall fall rates, vigorous older persons should not be overlooked in fall prevention projects.
