The aim of this population-based study is to evaluate the GWG in Campinas city, southeast of Brazil. A total of 1052 women, who delivered in the three major maternity hospitals in Campinas, were interviewed during postpartum period. The general average of GWG was . Of total women, 13.6% were obese and 24.6% were overweight and, in these groups, 55.9% and 53.7%, respectively, exceeded GWG according to the Institute of Medicine recommendations. 6.2% of total women had low body mass index (BMI) and 35.5% in this group had insufficient GWG. Overweight and obese women had a higher risk of excessive GWG and delivery by c-section. The c-section rate was 58.9% and increased according to GWG. Prematurity was more prevalent first in obese and then in low BMI women. Considering the high BMI in women in reproductive age, it is necessary to take effective guidelines about lifestyle and nutritional orientation in order to help women reach adequate GWG. All of them could improve prenatal outcomes and womenĄŻs heath as a whole. 1. Introduction Obesity is considered as one of the major public health problems in the world and is considered as an epidemic in developed countries and low income countries. Every year at least 2.6 million of deaths by obesity and overweight occur. It is known that a person with obesity or overweight has higher risk of dyslipidemia, diabetes mellitus (DM), and hypertension [1, 2]. In Brazil, the Health Ministry shows that 48% of women have higher weight than recommended. In SŁżo Paulo state it represents 48.6% of women with overweight [3]. During gestational period some women can exceed the weight gain recommended for pregnancy. It is estimated that 50% of women in infertility age are overweight or obese and 18% of women get pregnant with high body mass index (BMI), overweight, or obese [4]. According to World Health Organization (WHO) the prevalence of obesity during pregnancy is from 1.8% to 25.3%. The obesity during pregnancy increases maternal-fetal morbidity and it is related to many complications due to high risk pregnancy and delivery outcomes [3]. In public health services in Brazil, the majority of pregnant women do not have the expected range recommended for weight gain during pregnancy [5¨C9]. Several maternal complications occur due to overweight and obesity, including gestational diabetes, pregnancy induced hypertension and preeclampsia, and high rates of c-section, all of them associated with longer %U http://www.hindawi.com/journals/physiology/2014/956960/
