Abstract

Objective: To establish whether maternal weight gain during pregnancy has a correlation with baby’s weight gain. The study was conducted with Asian-Indian population in Bengaluru, India.


Materials and methods: A cross-sectional, observational study was conducted with 250 women at a maternity center in India who enrolled in the first trimester (around 5-8 weeks) of pregnancy and delivered in the center.


Results: The parameters recorded were age of the patient, gestational age at delivery, height, pre-pregnancy body weight, body mass index (BMI), pre-delivery body weight, weight gain during pregnancy and baby’s birth weight. Average gestational age of delivery was 38.3 weeks. Weight gained during pregnancy varied from zero to 27 kg. The top three weight gain in nor- mal BMI category were 20.4 kg, 19.7 kg and 19.4 kg and gave birth to 3.2 kg, 2.9 kg and 2.9 kg babies respectively. The lowest gained weight during pregnancy was in an overweight category where women gained 0 kg, 1.3 kg and 2 kg in the entire nine months and gave birth to babies weighing 3.2 kg, 2.7 kg and 2.8 kg respectively reflecting no underweight baby. One obese woman gained only one kg during pregnancy and her baby weighed 2.9 kg.


Conclusion: Gestational age, pre-pregnancy weight and pre-delivery weight had a positive correlation with the birth weight (statistically significant p< 0.006). However, total weight gained in pregnancy had a comparatively no correlation with the birth weight of the baby. It was not statistically significant (p=0.056).
