Introduction: Pre-eclampsia represents a major cause of maternal morbidity and morbidity in many parts of the world. Objective: To assess the prevalence of pre-eclampsia among at risk primi gravid mothers. Methods: A prospective longitudinal observational research design was used.120 at risk primigravid mothers for pre-eclampsia, who fulfilled the inclusion criteria, were selected by proportionate stratified random sampling. Results: It was observed that 31(30%) out of 103 of the at risk primigravid mothers developed preeclampsia. 11(33%) out of 33 mothers in Group A (age < 18 years), 10(28.5%) out of 35 mothers in Group B (age>30 years) and Group C (mothers with prepregnancy BMI>27.5 (obese) developed preeclampsia. Mothers of age > 30 years in group B developed severe pre-eclamptic features as early as 24 weeks of gestation. Educational qualification and socio-economic status was found to have statistical significant association with the level of pre-eclampsia at p<0.05 level. Conclusion: The underlying evidence base of the at risk factors in the study could be targeted at booking, so that a suitable surveillance and prophylactic strategies for pre-eclampsia could be developed.
