The pattern of pregnancy weight gain in prenatal care centers in Borujen 1999-2002

Background and aim: One of the important physiological changes during pregnancy is maternal weight gain. High weight gain results in postpartum obesity, and inadequate weight gain results in IUGR (Intra Utery Growth Rate) and low birth weight. The aim of this study was to determine maternal weight gain pattern in prenatal care centers of Boroujen city in 1999-2002. Method: Questionnaires were completed using files of 678 pregnant women in these centers. Based on the Body Mass Index (BMI) the cases were divided into four groups consisted of low weight (BMI<19.8), normal (BMI>19.8-26), high weight (BMI>26-29) and obese (BMI>29). Results: The mean weight gain of the whole sample was 11.4 kg, and it was 11.5 for normal and 10.3 for high weight groups, that was in the recommended range of Institute Of Medicine (IOM). Weight gain in the fourth and fifth months was linear. The mean weight gain was higher in the 3`d trimester compared to the 2nd one. Conclusion: Therefore drawing the chart of weight gain for each pregnant woman is better than determining weight gain for trimesters.
