Homeless urbanites are a heterogeneous population with unique health and social service needs. The study examined situational, behavioral, health-related and resource indicators in terms of their direct impact on frailty, hypothesized as a latent variable. Using structural equation modeling (SEM), a model was tested with 150 homeless men and women, ages 40–73, from three homeless day center drop-in sites on Skid Row and one residential drug treatment (RDT) facility that works with homeless parolees and probationers. In bivariate analyses with the latent construct frailty, months homeless (p < 0.01), female gender (p < 0.05), education (p < 0.05), comorbid conditions (p < 0.001), nutrition (p < 0.001), resilience (p < 0.001), health care utilization (p < 0.01), and falls (p < 0.001) were significantly associated with frailty. In the final path model, significant predictors of frailty included educational attainment (p < 0.01), comorbid conditions (p < 0.001), nutrition (p < 0.001), resilience (p < 0.001), and falls (p < 0.01). These findings will serve as a foundation for future nurse-led, community-based initiatives that focus on key predictors of frailty among the homeless and the development of interventions.
无家可归的城市居民是一个异质性群体,有独特的健康和社会服务需求。该研究考察了情境、行为、健康相关及资源指标对虚弱(假设为一个潜在变量)的直接影响。使用结构方程模型(SEM),对来自贫民窟三个无家可归者日间收容所和一个为无家可归的假释犯及缓刑犯提供服务的住院药物治疗(RDT)机构的150名年龄在40至73岁之间的无家可归男性和女性进行了模型测试。在与潜在结构虚弱的双变量分析中,无家可归月数(p < 0.01)、女性性别(p < 0.05)、教育程度(p < 0.05)、共病情况(p < 0.001)、营养状况(p < 0.001)、恢复力(p < 0.001)、医疗保健利用情况(p < 0.01)和跌倒情况(p < 0.001)与虚弱显著相关。在最终路径模型中,虚弱的显著预测因素包括教育程度(p < 0.01)、共病情况(p < 0.001)、营养状况(p < 0.001)、恢复力(p < 0.001)和跌倒情况(p < 0.01)。这些发现将为未来由护士主导、以社区为基础的举措提供基础,这些举措将关注无家可归者中虚弱的关键预测因素并制定干预措施。
