Frailty was assessed using the revised version of the Fried frailty criteria (weakness, exhaustion, low physical activity, shrinking, and slowness). This study aimed to evaluate the association between frailty and all-cause mortality. Cox proportional hazard models were used to evaluate the association between frailty category and all-cause mortality, adjusted for age, sex, race, education, poverty\u2013income ratio, smoking, alcohol, diabetes, arthritis, congestive heart failure, coronary heart disease, stroke, overweight, cancer or malignancy, chronic obstructive pulmonary disease, chronic kidney disease, and taking medicine for hypertension.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We gathered data of 2,117 participants with hypertension; 17.81%, 28.77%, and 53.42% were classified as frail, pre-frail, and robust, respectively. We found that frail [hazard ratio (HR)\u2009=\u20092.76, 95% confidence interval (CI)\u2009=\u20092.33\u20133.27] and pre-frail (HR\u2009=\u20091.38, 95% CI\u2009=\u20091.19\u20131.59] were significantly associated with all-cause mortality after controlling for variables. We found that frail (HR\u2009=\u20093.02, 95% CI\u2009=\u20092.50\u20133.65) and pre-frail (HR\u2009=\u20091.35, 95% CI\u2009=\u20091.15\u20131.58) were associated with all-cause mortality in the age group \u226565\u2005years. For the frailty components, weakness (HR\u2009=\u20091.77, 95% CI\u2009=\u20091.55\u20132.03), exhaustion (HR\u2009=\u20092.25, 95% CI\u2009=\u20091.92\u20132.65), low physical activity (HR\u2009=\u20092.25, 95% CI\u2009=\u20091.95\u20132.61), shrinking (HR\u2009=\u20091.48, 95% CI\u2009=\u20091.13\u20131.92), and slowness (HR\u2009=\u20091.44, 95% CI\u2009=\u20091.22\u20131.69) were associated with all-cause mortality.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This study demonstrated that frailty and pre-frailty were associated with an increased risk of all-cause mortality in patients with hypertension.
