Our aim was to identify latent factors underlying multiple observed risk factors for older adult falls and to examine their effects on falls by age and sex. We performed exploratory factor analysis on 13 risk factors in the Behavioral Risk Factor Surveillance System. We used log-linear regression models to measure the association between the identified factors and older adults reporting falls. We identified two underlying factors: physical and mental health limitations. These shared a 50% correlation. Physical health limitations were more strongly associated with falls among men (prevalence ratio = 1.68, 95% CI = 1.65-1.71) than women (prevalence ratio = 1.51, 95% CI = 1.49-1.54). As physical health limitations increased, men aged 65-74 had a greater association with falls compared with other age-sex subgroups. Our findings highlight the composite relationship between age, sex, and physical and mental health limitations in association with older adult falls, and support the evidence for individually tailored, multifactorial interventions.
我们的目的是确定老年人跌倒的多个观察到的危险因素背后的潜在因素，并按年龄和性别检查它们对跌倒的影响。我们对行为风险因素监测系统中的 13 个危险因素进行了探索性因素分析。我们使用对数线性回归模型来衡量确定因素与报告跌倒的老年人之间的关联。我们确定了两个潜在因素：身体和心理健康限制。这些因素共享 50%的相关性。与女性（流行率比=1.51，95%CI=1.49-1.54）相比，身体健康限制与男性跌倒的关联更强（流行率比=1.68，95%CI=1.65-1.71）。随着身体健康限制的增加，65-74 岁的男性与跌倒的关联大于其他年龄-性别亚组。我们的研究结果突出了年龄、性别以及身体和心理健康限制与老年人跌倒之间的综合关系，并为个性化、多因素干预提供了证据支持。
