Prediction of preeclampsia by mean arterial pressure and waist circumference
Journal Title: The New Indian Journal of OBGYN - Year 2019, Vol 6, Issue 1
Abstract
Objective: To evaluate the role of mean arterial pressure and antenatal waist circumference in early detection of preeclampsia. Methods: One hundred ninety (190) antenatal women were studied between 14 to 16 weeks of gestation for a period of one year. Mean arterial pressure was calculated by Burton’s formula and waist circumference was measured. Mean arterial pressure of 90 mm Hg or more and waist circumference of 80 cm or more was taken as cut off. Results: Out of 190 women 30 women had mean arterial pressure >90 mm Hg and out of 30 women 17(56.6%) developed preeclampsia while out of 160 women with mean arterial pressure <90 mm Hg only 21(13.3%) developed preeclampsia. Out of 80 women with waist circumference >80 cm 28 women (35%) developed preeclampsia while out of 110 women with waist circumference < 80 cm only 10(9%) developed preeclampsia. Conclusion: Mean arterial pressure is a good predictor of preeclampsia with high specificity 91.4% and negative predictive value of 86.8%. Waist circumference of 80 cm or more upto 16 weeks is a precise method of predicting preeclampsia with high sensitivity of 73.6% and negative predictive value of 90.9%.
