Comparison of Obstetric Outcomes Among Various Weight Strata in a Teaching Hospital in Southwest, Nigeria

Abstract

AIM:The aim of the study is to evaluate the trend in adverse obstetric outcomes of parturients across the spectrum of body mass index.METHODS:This is a cohort study of pregnant women who received obstetric care at the Obstetrics and Gynecology Department of the Ekiti State University Teaching Hospital, Ado-Ekiti, between January 2015 and December 2015. The data were prospectively collected into the Obstetric Data Registry of the department. Composite adverse maternal outcomes and composite adverse fetal outcomes were obtained for each group. Data were analyzed with SPSS version 24, and ap-value of less than .05 was considered statistically significant.RESULTS:Out of the 1,006 parturients, 334 (33.2%) were obese. Composite adverse maternal outcome increased from 35.1% for women with normal weight to 62.3% for obese women (p< .001). Composite adverse fetal outcome also increased from 25.9% for women with normal weight to 30% for obese women (p< .001). The odds of composite adverse maternal outcome were increased in overweight women (adjusted odds ratio [aOR] 1.52, 95% confidence interval [CI] [1.12, 3.49]) and obese women (aOR 1.65, 95% CI [1.21, 2.24]) compared with women with normal weight. Also, the odds of composite adverse fetal outcome were reduced in overweight (aOR 0.64, 95% CI [0.44, 0.93]) but increased in underweight (aOR 4.78, 95% CI [2.00, 11.44]) and obese (aOR 1.16, 95% CI [1.03, 12.39]) women.CONCLUSION:Composite adverse obstetric outcomes were increased in underweight, overweight, and obese women when compared with women with normal weight.
