Abstract

Objective: The aim of the study is to evaluate the effects of prepregnancy body mass index (BMI) and weight gain during pregnancy on the type of delivery, demographic findings and the rate of neonate’s hospitalization

Material and Methods: During 4-months period, pregnants who gave singleton birth after 36 weeks of gestation were included. Pregnants were categorized into groups according to their prepregnancy BMI as ‘underweight’ (under 18.5 kg/m2), ‘normal’ (18.5–24.9 kg/m2), ‘overweight’ (25–29.9 kg/m2) and ‘obese’ (more than 30 kg/m2). The demographic findings of the pregnants, prepregnancy BMI, weight change during pregnancy, type of delivery, the demographic findings and the rate of neonate’s hospitalization were evaluated.

Results: One-hundred and seventy-seven pregnants included. Seven percent (n=12) of them categorized as ‘underweight’, 72% (n=128) as ‘normal’, 15% (n=27) as ‘overweight’ and 6% (n=10) as ‘obese’. The mean age of pregnants was different (p=0.001), the rate of antenatal problems (gestational diabetes and hypertension) was similar (p=0.39) between the groups. Most of the pregnants were high school or university graduates. Weight gain during pregnancy was different (p=0.009), whereas change in BMI was similar (p=0.2) between groups. Type of delivery and the demographic findings of the newborns were similar (p>0.05), but the rate of neonate’s hospitalization was different (p=0.032) between the groups. The rate of neonate’s hospitalization was highest in ‘overweight’ group (30%). Change in BMI during pregnancy did not effect the demographic findings and the rate of neonate’s hospitalization, whereas the rate of cesarean section was higher in pregnants whose change in BMI was ‘high’ or ‘very high’ during pregnancy (p=0.015).

Conclusion: It has been demonstrated that prepregnancy BMI and change in BMI during pregnancy effect the type of delivery and the rate of neonate’s hospitalization. Planned pregnancy with appropriate body weight, balanced weight gain during pregnancy is important for both maternal and neonatal health.
