Abstract Objective To research the suitable pregnancy weight gain value of the maternal with different pre-pregnancy body mass index (BMI), predict the appearence probability of the macrosomia using the suitable pregnancy weight gain value. Methods From January 2016 to December 2016, 500 cases of maternal who gave birth in Huadu District People's Hospital of Guangzhou were recruited into this study. According to the pre-pregnancy body mass index, these maternal were divided into low BMI group (group A, 149 cases, BMI<18.5 kg/m2), normal BMI group (group B, 225 cases, 18.5 kg/m2≤BMI<25.0 kg/m2) and high BMI group (group C, 126 cases, BMI≥25.0 kg/m2). The incidence of macrosomia in three groups was counted. The relationship between macrosomia incidence and weight gain during pregnancy was investigated. The consistency of the suitable pregnancy weight gain value and the IOM recommendation value about the three groups was observed. The occurrence of macrosomia was predicted by using the suitable pregnancy weight gain value. Results The suitable pregnancy weight gain value of group A and C had the same value with the value recommended by IOM, was 12.5-18.0 kg and 7.0-11.5 kg respectively. The suitable pregnancy weight gain value of group B was different with the IOM recommended value. The suitable pregnancy weight gain value for the group B was 10.5-15.0 kg. The area under the ROC curve was 0.693, 0.719 and 0.690 respectively. The positive predictive value was 70.73%, 58.62% and 59.02%. The negative predictive value was 73.42%, 74.19% and 76.27% respectively. Conclusion The IOM recommended pregnancy weight gain value is not suitable for the maternal in our region. Based on the characteristics of maternal physical modernised in the added value of pregnancy weight can better predict the occurrence of macrosomia and reduce the incidence of adverse birth outcomes.
