Objectives: To finds out the prevalence of anaemia among no pregnant non lactating women of reproductive women living in urban slums of Lucknow city and to study the factors influencing the anaemia status of women of urban slums. Methods: Descriptive cross sectional study was conducted among 410 ever married, non- pregnant and non- lactating women of reproductive age group (15-45 years) residing in urban slums of Lucknow city. Women were selected using cluster sampling method. Heamoglobin estimation was done by using hemocue method. Structured questionnaire was used for interview wand anthropometric measurement and nutritional assessment of all the women was also performed. Results: The overall prevalence of anaemia was sixty nine percent among non-pregnant, non-lactating women of reproductive age in urban slums. Prevalence of mild, moderate, and severe anaemia was 48.3%, 18.5% and 2.2% respectively. On logistic regression analysis, intake of iron, body mass index of the women, access to media and use of the contraceptives by the woman were the only independent predictors found to be significantly associated with prevalence of anaemia. Conclusions: Burden of anaemia is high among non pregnant non lactating women of reproductive age group urban slum women. National Nutrition Programs should target this vulnerable women group also.
