Association of obesity and overweight with the risk of preeclampsia in pregnant women: an observational cohort study.

Abstract

According to the World Health Organization, obesity is considered a pervasive global epidemic with significant medical and social implications. In antenatal mothers, the prevalence varies from 40% in Western countries to 12% in India which leads to life-threatening complications-preeclampsia and eclampsia. This study delves into the association between body mass index (BMI) and preeclampsia, among primi antenatal mothers with pregnancy-induced hypertension (PIH). An observational cohort (prospective) study was conducted among 150 primi antenatal mothers with pregnancy-induced hypertension in Government Headquarters Hospital, Tamil Nadu, India. Demographic data, body mass index, and pregnancy outcomes were assessed. Statistical analysis was performed using the SPSS 28.0 version. Among 150 pregnant women, 63 (42%) were overweight, and 13 (8.7%) were obese. Higher BMI was significantly associated with maternal complications, especially preeclampsia (P < 0.001). Moreover, other complications such as abruptio placenta, pulmonary edema, eclampsia, and postpartum hemorrhage were not significantly associated with BMI. The study calls attention to the persistent link between BMI and preeclampsia, emphasizing the need for comprehensive strategies aligned with the Sustainable Development Goal. Despite ongoing efforts, the study suggests a lack of substantial change in the prevalence of preeclampsia associated with increased BMI, prompting the exploration of innovative interventions to address weight-related factors during pregnancy for improved maternal and neonatal well-being.
