摘　　要：目的探讨孕前体质量指数(BMI)与孕1~6月增重对孕中期妇女体成分影响的交互作用,为完善优生优育地方策略及准孕妇备孕提供参考。方法选取2020年5月—2021年5月在兰州市妇幼保健院产科门诊定期产前检查的25~26周健康孕妇422例,根据孕前BMI和孕1~6月增重情况进行分组,探讨不同组别各体成分的情况;采用双变量响应面模型展示孕前BMI与孕1~6月增重对孕中期体成分的交互作用。结果孕中期妇女各体成分指标在孕前BMI和孕1~6月增重分组中差异均有统计学意义(均P<0.05);孕前高BMI和孕1~6月增重过多均会造成体成分各指标的增加,当孕前高BMI和孕1~6月增重过多共存的情况下,体成分各指标达到峰值。结论孕前BMI和孕1~6月增重均是影响孕妇孕中期体成分的重要因素,并且随着孕前BMI和孕1~6月增重过多,各体成分指标均有不同程度的升高,提示在做好孕产期常规保健的同时,更需关注孕前保健,据孕前营养状况,通过均衡膳食搭配、适度有氧运动合理控制孕期增重,有利于防止不良妊娠结局。Objective To investigate the interaction between pre-pregnancy body mass index(BMI)and weight gain from 1 to 66 months of pregnancy on the body composition of women in the middle of pregnancy,and to provide reference for improving local strategies of healthy birth and healthy care and pregnant women's pregnancy preparation.Methods From May 2020 to May 2021,422 healthy pregnant women between 25 and 26 weeks of age who received regular prenatal examination in the Department of Obstetrics in Lanzhou Maternal and Child Health Hospital were selected.They were divided into groups according to their pre-pregnancy BMI and weight gain from 1 to 6 months of pregnancy,and the body composition of different groups were discussed.A bivariate response surface model was used to investigate the in⁃teraction between pre-pregnancy BMI and weight gain from 1 to 6 months of pregnancy on body composition in mid-pregnancy.Results There were statistically significant differences in BMI before pregnancy and weight gain between 1 and 6 months of pregnancy among women in the second trimester(P<0.05).Both high BMI before preg⁃nancy and excessive weight gain between 1 and 6 months of gestation resulted in the increase of body composition indexes.When high BMI before pregnancy and excessive weight gain between 1 and 6 months of gestation co-existed,body composition indexes reached the peak.Conclusion BMI before pregnancy and weight gain between 1 and 6 months of pregnancy are both important factors affecting the body composition of pregnant women in the middle of pregnancy,and with the excessive BMI before pregnancy and weight gain between 1 and 6 months of pregnancy,all body composition indicators are increased to varying degrees,suggesting that while routine health care during preg⁃nancy and perinatal period should be done well,prepregnancy health care should be paid more attention to.According to the nutritional status before pregnancy,Reasonable control of weight gain during pregnancy through balanced diet and moderate aerobic exerc
