Objective: To estimate the short-term (14 months) impact of anemia on mortality amonganemia Mexican older adults (OAs). Method: Longitudinal analyses using data from a quasi-experimental study in a non-contributory pension program in Mexico with a sample of 3,621 OAs aged 65 to 74 years. Data on health, nutrition, life conditions, and mortality were gathered at both baseline and follow-up. Logistic regression model was used to estimate the impact of anemia and hemoglobin quintiles on mortality.Results: Overall mortality rate was 2.1%. Both mild anemia and moderate/severe anemia increased mortality risk at 14 months (odds ratio [OR] = 2.04, 95% confidence interval [CI] = [1.1, 4.1]; and OR = 6, 95% CI = [2.1, 16.9], respectively). Discussion:In the short term, degree of severity of anemia is an independent predictor of mortality risk. Because anemia is a modifiable factor, further research is required to better understand this condition in terms of main causes, prevention, treatment, and impact on OAs’ survival.
