Introduction: Slum population, ranked among the neediest and ironically, the most underserved group in terms of health care has the worst dietary and nutritional profile. Women of reproductive age residing in slums are especially vulnerable to malnutrition because of social and biological reasons. Hence, the present study was conducted to assess the prevalence of chronic energy deficiency and its socio-demographic correlates among women in various slum areas of Amritsar city. Material and Methods: A total of 30 clusters of 7 units each were taken to make a sample of 210 units. The women who had delivered within one year before the interview were taken as study units. They were interviewed with the help of a pretested proforma Body Mass Index was used to assess the nutritional status of women. Regression analysis was applied to evaluate the effect of various socio-demographic factors on chronic energy deficiency. Results: On bivariate analysis nativity, socio-economic status, literacy, and contact with health worker were the statistically significant factors affecting chronic energy deficiency among women. But, multivariate regression analysis identified only literacy of the women (OR=0.31, CI= 0.11 to 0.83, p= 0.03) as significant factor affecting the nutritional status of women. Conclusion: Literacy of women is the only statistically significant factor determining the prevalence of chronic energy deficiency. Therefore, the overall educational status of women should be improved to have better nutritional health.
