RESUMO
The aim was to study the prevalence of overweight and obesity in Moscow pregnant women, as well as to conduct a comparative study of normal and excessive women`s body weight influence on the course and outcome of pregnancy and delivery, anthropometric indices and state of newborn`s health, to assess women's dietary intake and to develop approaches to nutritional correction of overweight and obesity in pregnant women. The prevalence of overweight and obesity among pregnant women in Moscow in 2009-2011 was 8.3% of the total number of pregnant women observed. The average weight gain during pregnancy in women with overweight and obesity amounted to 13.8±5.2 kg, that was higher then the weight gain in women with normal body weight (11.7±4.5 kg). In women with overweight and obesity there was an increased risk of complications during pregnancy (preeclampsia, anemia), delivery (more frequent operational, premature and delayed delivery), as well as 2-3 times more frequent birth of children with significantly enhanced birthweight, including macrosomia. A study of dietary intake of women surveyed showed a deviation of diets of pregnant women with overweight and obesity from the physiological standards, which is the increase of fat and saturated fatty acids by 25%, reduced carbohydrate content up to 30%, and the reduction in the diet of women of some micronutrients (folic acid, vitamin A, ß-carotene). The main principles of nutritional correction of diets of pregnant women who are overweight and obese have been presented as well as recommended set of products and exemplary diet for this category of women.
