Hypertension and frailty are associated and often coexist in older adults. Few studies have examined the association between hypertension and frailty in Chinese population. We explored the prevalence of and the factors associated with frailty as well as whether frailty could identify patients at risk of adverse outcomes among older adults with hypertension. Data were from the Beijing Longitudinal Study of Aging. A total of 1111 hypertensive participants aged ≥60 years old who completed the comprehensive geriatrics assessment were included. All participants were followed up for 8 years. The total number of deaths was 604. Frailty was assessed by the 68‐item frailty index. Stepwise forward logistic regression was used to explore the association between the associated factors and frailty in hypertensive participants. The prediction for mortality was assessed using the adjusted Cox proportional hazards model. Two hundred and eighteen older adults were determined as frail (prevalence rate: 19.6%). Frail older adults with hypertension had worse physical performance, worse psychological, and social function, as well as worse lifestyle habits, compared to nonfrail older adults with hypertension. Chair stand test failure, balance test failure, fracture, disability, depression, and physical frailty measured with modified frailty phenotype were independently associated with frailty. Frailty was associated with a higher 8‐year mortality, hazard ratio (HR) = 3.40, adjusted for age and sex, HR = 2.61. Frailty is associated with poorer physical function and higher mortality in community‐dwelling hypertensive older adults in China. These findings emphasize the importance and need for frailty intervention and prevention in older adults with hypertension.
