Abstract
OBJECTIVES: To determine whether hyperglycemia is related to prevalent frailty status in older women. DESIGN: Secondary data analysis of baseline data of a prospective cohort study. SETTING: Baltimore, Maryland. PARTICIPANTS: Five hundred forty‐three women aged 70 to 79. METHODS: Research used baseline data from 543 participants in the Women's Health and Aging Studies I and II aged 70 to 79 who had all variables needed for analyses. The dependent variable was baseline frailty status (not frail, prefrail, frail), measured using an empirically derived model defining frailty according to weight loss, slow walking speed, weakness, exhaustion, and low activity (1–2 characteristics present=prefrail, ≥3=frail). Covariates included body mass index (BMI), interleukin‐6 (IL‐6), age, race, and several chronic diseases. Analyses included descriptive methods and multinomial logistic regression to adjust for key covariates. RESULTS: A hemoglobin A1c (HbA1c) level of 6.5% or greater in older women was significantly associated with higher likelihood of prefrail and frail status (normal HbA1c 30.0 kg/m2) body mass index (BMI), interleukin‐6, and all chronic diseases evaluated, but controlling for these covariates only minimally attenuated the independent association between HbA1c and frailty status. CONCLUSION: Hyperglycemia is associated with greater prevalence of prefrail and frail status; BMI, inflammation, and comorbidities do not explain the association. Longitudinal research and study of alternative pathways are needed.
