Is there any materno- foetal risks in mothers with gestational weight gain (WHO & IOM) based on their pre-pregnancy body mass indices? Our experience in a tertiary care teaching institution in North Kerala

: This research was done to learn the impact of pre-pregnancy BMI and gestational weight gain (GWG) on subsequent risks of adverse pregnancy outcomes in a tertiary care teaching institution in North Kerala, India. A descriptive study in a tertiary care teaching institution in Kozhikode, North Kerala. : 296 singleton pregnant women with BMI categorised as per Asian Standards and adverse maternal outcomes were looked out for. Pregnant women were underweight (82.8%) achieved less than recommended weight during pregnancy as compared to 18.4% obese mothers. Mothers with high BMI gained more than recommended weight during pregnancy as compared to the underweight and normal weight woman. GDM was 3.03 times(p=0.019)and Hypertensive disorders of pregnancy was 1.116 times more common in higher pre-pregnancy BMI mothers. In the present study, gestational weight gain had no impact on maternal anaemia, Gestational diabetes, Gestational hypertension, foetal growth restriction and rate of caesarean deliveries. A statistically significant positive correlation was obtained between pre-pregnancy BMI and baby weight, p<0.001. A statistically significant positive correlation was obtained between gestational weight gain and baby weight, p=0.005. Weight gain during pregnancy had no significant impact on maternal pregnancy outcomes and caesarean delivery.
