Weight Gain and Food Group Consumption Patterns in Pregnant Women of North and East Hospitals of Tehran

Considering the important role played by nutrition in pregnancy outcomes weight gain during pregnancy, and overweight/obesity in later life, this study was conducted to assess the weight gain and food consumption patterns in pregnant women of Tehran. Materials and Materials: This study was a cross-sectional study with quota sampling based on the aim (n=265). Data collected by a questionnaire, included two sections: Demographic/socio-economic and 24hour dietary recall, completed by expert interviewers. Mothers’ height and weight were measured and BMI were computed. Pre-pregnancy weight was obtained from the historical files. Statistical analysis was done using Chi-Square, student and paired t-test, Pearson correlation and regression analysis. Of subjects, 57% were normal weight, 15% underweight, 16% overweight and 12% were obese. Mean weight gain in the overweight and obese groups was higher than the recommended level (p<0.01); based on FGP recommendations for pregnant women, they consumed less bread/cereals, and milk/dairy products, and more meat/its alternatives, vegetables, fruits, and sweets/fats. The regression model showed that weight gain during pregnancy increased in the number of children and gestational age and decreased with increase in age and pre-pregnancy BMI. Monitoring weight gain during pregnancy, implementing FGP recommendations and awareness regarding about the proper weight gain are the main strategies for preventing post partum overweight/obesity, especially in obese and older women.
