Brief Summary:
The participants are divided into subjects or controls based on the BMI taken during the first trimester of pregnancy upon recruitment. Participants with a BMI of ≥23kg/m2 were recruited as subjects (labelled as obese group) and those with BMI of 18.5-23kg/m2 were recruited as controls. Total gestational weight gain was calculated based on the difference between third trimester weight and first trimester weight. All participants who fulfilled the inclusion and exclusion criteria were recruited after informed consent. Demographic data of all participants were recorded. At first trimester, the participants' weight and height were recorded for calculation of BMI. At every trimester visit, the following were recorded: i) blood pressure using sphygmomanometer after 15 minutes of rest ii) mid-stream urine for presence of proteinuria iii) weight. The participants were followed up until the point of delivery. Occurrence of adverse pregnancy outcome, fetal outcome, and birth weight were documented. The pregnancy outcomes measured in this study included the need of primary caesarian section, the occurrence of pregnancy-induced hypertension (PIH), pre-eclampsia, and gestational age at delivery. The neonatal outcomes measured in this study included neonatal intensive care unit (NICU) admission, stillbirth, preterm delivery, occurrence of macrosomia and low birth weight, and neonatal birth weight.
