BACKGROUND Anemia is a common morbidity in elderly persons (aged 60 years or above). In India, in recent years, the number of old age homes (OAHs) and the residents living in them has increased significantly. OBJECTIVE The aim of this study was to estimate the prevalence of anemia among elderly persons living in OAHs. METHODS This was a cross-sectional study among individuals living in OAH in Delhi, India. Using combination of location and type of OAH, 28 clusters of almost equal sizes were created, of which 13 clusters were randomly selected, and all elderly persons living therein were selected for the study. Sociodemographic profile was recorded using a self-designed, semistructured interview schedule. Hemoglobin (Hb) was estimated using HemoCue Hb 201+ system. Binary Logistic regression was used to assess the socioeconomic determinants of anemia. RESULTS The study included 334 elderly persons, with a mean (standard deviation [SD]) age of 75.2 (8.6) years and mean (SD) Hb of 11.6 (1.7) g/dL. The mean (SD) Hb in men was 12.1 (1.7) g/dL compared to 10.9 (1.5) g/dL among women (P < 0.0001). The overall prevalence of anemia was 68.7% (95% confidence interval 63.9, 73.4); among those who were anemic, 47.4% had mild anemia, 47.0% had moderate anemia, and 5.6% had severe anemia. The prevalence of mild anemia was 45% in men compared to 24.8% in women. The odds of anemia among ≥80 years was 2 times that among 60-69 years (P < 0.029). CONCLUSIONS The prevalence of anemia among elderly persons in OAHs is high in Delhi, India and increased with age.
