ABSTRACT
INTRODUCTION: To identify the association between maternal obesity and perinatal adverse outcomes in a population from the Colombian northeast. PATIENTS AND METHOD: Multicenter, prospective, transverse study with patients who consulted and completed their pregnancy at the Clinica Materno Infantil San Luis and Hospital Universitario de Santander, between January 2019 and March 2020. The nutritional status of the patients was classified according to the Rosso-Mardones curve and obese and normal- weight pregnant women were included. The main outcome was prematurity, and the secondary ones were intrauterine growth restriction, large for gestational age, and early neonatal hypoglycemia. The analysis was made in subgroups of pregnant women without comorbidities. The strength of associa tion was estimated through binomial regression (RR), and a confidence interval of 95%, adjusted by maternal age as a confounding variable according to a counterfactual model. A p- < 0.05 value was considered statistically significant. RESULTS: 283 obese pregnant women and 276 normal body mass index pregnant women were included. There was a significant association between maternal obesity and prematurity (RR 2.5; CI95% 1.4-4.2), early neonatal hypoglycemia (RR 7.1; CI95% 2.1-23.7), and large for gestational age (RR 6.6; CI95% 3,3-13,1). These findings were similar in pregnant wo men without maternal hypertension or diabetes. CONCLUSION: Maternal obesity is associated with prematurity, large for gestational age, and early neonatal hypoglycemia; even in patients without maternal hypertension and diabetes.
