Introduction: Anaemia in pregnancy remains one of the most intractable public health problems in the developing countries. World Health Organization has estimated that more than half of the pregnant women in the world are anemic. Anaemia during pregnancy is associated with adverse infant outcomes, including low birth weight, preterm delivery and perinatal mortality, and it may also be associated with childhood intellectual disability. Objective: To estimate the prevalence of anaemia in primigravida, classify the severity of anaemia in different age groups. Material & Methods: It is a cross sectional study. Haemoglobin of 187 primigravida subjects in a tertiary hospital was estimated. The subjects were divided into age groups, below 20 years, 20-25 years and more than 25 years. The mean and standard deviations of haemoglobin in different age groups were calculated. Observation & Results: Out of 187 primigavida pregnant women 91.1% below 20 years, 77.77% from 20-25 years and 36.58 % of more than 25 years were anaemic. Their mean Hb was 9.89gms /100 ml, 9.9gms / 100 ml and 11.1gms / 100ml respectively.
