Frailty is a state of vulnerability to stressors which may result in high mortality, morbidity, and health-care utilization in older adults. Whether health literacy, graph literacy and numeracy are associated with frailty is unknown.
To assess the association of health literacy, numeracy and graph literacy with frailty in male veterans.
This is a retrospective study of 470 cognitively intact, non-depressed veterans who completed evaluations of health literacy, numeracy and graph literacy at Miami VA facility in 2012. A 43-item frailty index was created as a proportion of all potential variables (demographics, comorbidities, number of medications, laboratory tests, and activities of daily life). Odds ratios and 95% confidence intervals were calculated by multinomial logistic regression models with frailty status (robust, prefrail and frail) as the outcome variable, and with health literacy, numeracy, and graph literacy scores as independent variables. Age, race, ethnicity, education, socio-economic status, and comorbidities were considered as covariates.
Patients were 100% male, 40% White, 82% non-Hispanic, mean age was 56.8 years. The proportion of robust, pre-frail and frail was 10.0%, 61.3% and 28.7%, respectively. Neither health literacy nor objective nor subjective numeracy was associated with frailty after adjustment for covariates. In contrast, higher graph literacy scores were associated with a lower risk for frailty (p = .015) even after adjusting known risk factors for frailty.
Neither health literacy nor numeracy is associated with frailty. Higher graph literacy score is associated with a lower risk for frailty even after adjusting for known risk factors for frailty.
衰弱是一种对压力敏感的状态，可能导致老年人死亡率、发病率和医疗保健利用率增加。目前尚不清楚健康素养、图形素养和计算素养是否与衰弱有关。
评估健康素养、计算素养和图形素养与男性退伍军人衰弱的关系。
这是一项回顾性研究，纳入了 2012 年在迈阿密退伍军人事务部完成健康素养、计算素养和图形素养评估的 470 名认知正常、无抑郁的退伍军人。衰弱指数通过所有潜在变量（人口统计学、合并症、药物数量、实验室检查和日常生活活动）的比例创建。使用多项逻辑回归模型，将衰弱状态（健壮、衰弱前期和衰弱）作为因变量，将健康素养、计算素养和图形素养得分作为自变量，计算比值比和 95%置信区间。考虑了年龄、种族、民族、教育、社会经济地位和合并症作为协变量。
患者均为男性（100%），40%为白人，82%为非西班牙裔，平均年龄为 56.8 岁。健壮、衰弱前期和衰弱的比例分别为 10.0%、61.3%和 28.7%。调整协变量后，健康素养和客观或主观计算素养均与衰弱无关。相比之下，较高的图形素养得分与衰弱风险降低相关（p = .015），即使在调整了已知的衰弱风险因素后也是如此。
