Association of total gestational weight gain and maternal and perinatal outcomes among pregnant patients using the institute of medicine 2009 gestational weight gain guidelines in a tertiary hospital / Philippine Journal of Obstetrics and Gynecology

ABSTRACT

Background@#The aim of the study was to determine the association between total gestational weight gain (TGWG) and maternal and perinatal outcomes based on the Institute of Medicine 2009 gestational weight gain (GWG) guidelines among pregnant patients of the department of obstetrics and gynecology in a tertiary hospital@*Methodology@#Our analysis was carried out in a private hospital in Metro Manila, specifically in a tertiary hospital, in a prospective cohort study that included 565 pregnant women from June 1, 2020, to April 30, 2021. Body mass index (BMI) at initial prenatal visit <14 weeks’ age of gestation and upon admission, birth weight, comorbidities were all assessed and recorded. Our main outcome measures were TGWG, perinatal outcomes (small for gestational age, large for gestational age, intrauterine fetal demise, and admission to neonatal intensive care unit), and maternal outcomes (gestational diabetes mellitus, gestational hypertension, preeclampsia/eclampsia, and preterm birth). The baseline anthropometric, maternal and neonatal outcomes were analyzed using mean, standard deviation, range and chi‑square test was used to correlate total gestational weight gain against maternal and perinatal outcomes and a P‑value less than 0.05 was statistically significant@*Results@#In this study, the mean BMI was 23.6 kg/m2, and based on BMI classification, 8% were underweight, whereas 28.1% and 9% were overweight and obese, respectively. Based on the recommendations of TGWG on each BMI category, using Chi‑square test, there was a significant association of having excess GWG and inadequate GWG against maternal and perinatal outcomes@*Conclusion@#Based on the study, women having excess or inadequate TGWG has effects on maternal and perinatal outcomes. Furthermore, women that are classified as overweight and obese in the first trimester have a higher risk of developing comorbidities
