Anemia represents a global health problem that negatively impacts quality of life in elderly population; however, its impact on the geriatric syndrome of frailty is unclear. We examined the prevalence of anemia among elderly and sought a relationship between hemoglobin and the phenotype of frailty. Baseline hemoglobin quintiles and anemia were assessed in relation to frailty status in a prospective study with 1,933 older community-dwelling adults enrolled in the Study on Aging and Dementia in Mexico (SADEM). Logistic regression was used to model the relationship between frailty and Hb, adjusting for risk factors of frailty, sociodemographic data, cognitive decline, chronic diseases, and some risky habits. Prevalence of frailty was 8.3 %. Frailty risk was highest at the lowest hemoglobin quintile (
