Predicting the birth of a large fetus in obese women

Purpose. To determine the risk of macrosomia in pregnant women as a function of body weight.Material and Methods. The study included 754 patients. All patients were divided into three groups. Group 1 included 262 obese patients with an average body mass index (BMI) of 33.1 (31.4; 35.9) kg/m2, aged 30 (27; 34) years. Group 2 comprised 260 overweight patients with an average body mass index of 27.5 (26.4; 28.7) kg/m2, aged 29 (25; 33) years. Group 3 (control) included 232 patients with normal body weight, BMI of 22.6 (21.0; 23.8) kg/m2, aged 28 (25; 31.5) years. Anthropometric data were assessed in all patients with the performance of general clinical and laboratory examinations.Results. Based on the results of logistic regression analysis for continuous variables, a prognostic model for the birth of a large fetus with a probability of up to 70.3% was constructed.
