To explore the association between baseline life-space mobility and nursing home (NH) admission among community-dwelling older adults over 6 years.
Using data from a prospective, observational cohort study consisting of a random sample of 1,000 Medicare beneficiaries ≥ 65 years of age stratified by race (African American and non-Hispanic White), sex, and rural/urban residence. Baseline life-space mobility was assessed during in-home interviews. Participants were contacted by telephone every 6 months to ascertain NH admissions, Life-Space Assessment (LSA) scores, and vital status (living or deceased). Using multivariate logistic regression, the significance and independence of the relationship of life-space mobility with NH admission were examined.
Over 6 years, the odds of NH admission increased 2% for every one point lower baseline life-space score independent of previously recognized risk factors.
The LSA may be a useful tool to identify older adults at risk of NH admission.
探究社区居住的老年人在 6 年以上的时间里，其基线生活空间流动性与入住养老院（NH）之间的关联。
利用一项前瞻性观察队列研究的数据，该研究由按种族（非裔美国人和非西班牙裔白人）、性别和城乡居住情况分层的 1000 名 Medicare 受益人的随机样本组成。基线生活空间流动性在家庭访谈期间进行评估。通过电话每 6 个月联系一次参与者，以确定 NH 入院、生活空间评估（LSA）评分和生存状况（生存或死亡）。使用多变量逻辑回归，检验生活空间流动性与 NH 入院之间关系的显著性和独立性。
在 6 年期间，与之前确定的风险因素无关，基线生活空间评分每降低 1 分，NH 入院的几率就会增加 2%。
LSA 可能是识别有 NH 入院风险的老年人的有用工具。
