Abstract

Objective: To determine the impact of maternal weight gain during pregnancy on expected fetal weight and neo-natal birth weight.
Subjects and methods: This prospective cohort study was conducted on 159 pregnant women; 53 women with normal weight as Group (A), along with 53 overweight pregnant women as a Group (B) and 53 obese pregnant women as a Group (C) according to BMI. The maternal weight gain was calculated and correlated to expected fetal weight and fetal birth weight. The study was approved by the Ethics Committee, and all patients gave their informed consent before inclusion in the study.  
Results: We found that there was a statistically positive cor-relation between maternal weight gain, expected fetal weight and fetal birth weight in 3 study groups. maternal weight gain was significant independent predictor of fetal weight (p≤ 0.001), as maternal weight gain can predictor fetal weight in group (A) 38.4% , group (B) 46.2%  and group (C) 42.6%  . 
Conclusion: The current study has demonstrated that preg-nancy weight gain was associated with a significant effect on birth weight regardless of BMI. Additionally, maternal weight gain could be considered as a significant predictor of fetal weight.
