Physical frailty and health outcomes of fitness, hormones, psychological and disability in institutionalized older women: an exploratory association study.

Little is known about symptoms associated with frailty in institutionalized Portuguese older adults. This study aimed to investigate the association of frailty with diverse geriatric health characteristics. Cross-sectional data from 140 women aged between 75 and 85 years were analyzed. Data were collected between March and June, 2016. Fried's definition of physical frailty, psychological, sex hormones, disability and physical fitness outcomes were examined. The prevalence of frailty was 40%. Frail women had lower scores in cognitive and physical fitness, and higher scores for depressive symptoms and comorbidities. Significant correlations emerged between frailty and disability, fear of falling, aerobic resistance and cognition. Regression analyses and Receiver Operating Only aerobic resistance (sensitivity [93-96%]; specificity [74-77%], = .001) and cognition (sensitivity [77-88%]; specificity [65-71%], < .001) remained in the equation as independently related to physical frailty. A trend of significant differences in lower systolic blood pressure may reflect being less physically active and/or having more systemic comorbidity. Fried's model can be considered applicable. The 2-minute step test and the Mini Mental State Examination could better identify frail populations. The role of blood pressure and level of education in physical frailty status needs to be further explored.
