OBJECTIVES To investigate the prevalence and factors associated with frailty in rural and urban older outpatients in Vietnam. METHODS This cross-sectional study included 1084 outpatients (aged ≥60 years; mean age 71.7 ± 7.4 years; female 65%) from rural (n = 600) and urban (n = 484) geriatric clinics from December 2019 to July 2020. Frailty was assessed using Fried frailty phenotype. Factors associated with frailty were assessed using logistic regression. RESULTS Overall, frailty prevalence was 28% (rural, 26%; urban, 30%; p = 0.220). Factors associated with frailty were older age (odds ratio [OR] 1.16, 95% confidence interval [CI] 1.13-1.20, p < 0.001), being underweight (OR 1.88, 95% CI 1.10-3.27, p = 0.025) and limitations in activities of daily living (ADLs) (OR 6.04, 95% CI 1.63-22.41, p = 0.007) and instrumental ADLs (OR 5.83, 95% CI 3.74-9.08, p < 0.001). Higher education (OR 0.47, 95% CI 0.29-0.76, p = 0.002) and productive work (OR 0.39, 95% CI 0.21-0.71, p = 0.002) were protective factors against frailty. CONCLUSIONS In Vietnam, the prevalence of frailty in older outpatients was 28%, though not significantly different between urban and rural areas. Older age, being underweight and limitations in functional status can increase the odds of frailty, but higher education and productive work can reduce the odds of frailty.
