Obesity Increases Maternal Complications in Pregnant Women of Sinop: A Retrospective Cohort Study

Abstract

Obesity is a chronic metabolic disease that can promote serious comorbidities as maternal complications. Thus, the objective of this study was to analyze the prevalence of overweight and obesity, and the incidence of maternal complications in pregnant women of Sinop, Mato Grosso, Brazil. It was a retrospective cohort study with clinical and epidemiological data collected from the medical records of pregnant women diagnosed in 2020. Pregnant women were subdivided into three groups: eutrophic, overweight, and obese. Data from 700 pregnant women were evaluated, 251 in the eutrophic group, in the 220 overweight group and 229 in the obese group. The percentage of pregnant women with diabetes mellitus and arterial hypertension was significantly higher in the overweight and obesity groups when compared with the eutrophic group. The incidence of gestational diabetes mellitus was significantly higher in the overweight and obese groups when compared with the eutrophic group (p < 0.0001). The incidence of gestational arterial hypertension was also significantly higher in the overweight (6.8%) and obese (12.7%) groups when compared with the eutrophic group (1.2%) (p < 0.0001). The incidence of pre-eclampsia was also higher and statistically different in the overweight and obese groups. In conclusion, it was observed that most of the pregnant women presented with overweight/obesity and that this excess body weight contributed significantly to the incidence of several maternal complications.
