摘　　要：目的探讨体质指数 (BodyMassIndexBMI)及其增长对妊娠结局的影响。方法根据10 0 0例孕妇的身高及其孕 13周和终止妊娠前的体重 ,按公式计算其相应孕周的BMI,孕 13周至终止妊娠前BMI的总增幅和平均每周增幅 ,随访和比较孕期BMI不同增长状态的孕妇的妊娠结局。结果孕 13周BMI>2 3 7的孕妇 ,中重度妊高征的发生多于同孕周BMI≤ 2 3 7的孕妇 (P <0 0 1) ,中重度妊高征孕 13周后BMI平均每周增加 0 2 18± 0 0 49,与对照组比较差异有显著性 (P <0 0 5 ) ;孕 13周至终止妊娠前BMI总增幅≥ 6的孕妇 ,巨大儿及与之相关的剖宫产和高危新生儿的发生相应增加 ,与BMI总增幅 <6的孕妇比较 ,差异有显著性 (P <0 0 1和P <0 0 5 )。结论孕 13周BMI较高的孕妇 ,中重度妊高征发生增加 ;中重度妊高征 13周后BMI平均每周增幅高于无妊高征者 ,妊娠中晚期BMI总增幅较高者 ,巨大儿及与之相关的剖宫产和高危新生儿增加。提示 :孕 13周BMI>2 3 7可作为预测中重度妊高征的指标 ;避免孕期BMI大幅增长是改善妊娠结局的一项有价值的工作。Objective To explore the effect of body mass index(BMI) increase on pregnancy. Methods 1 000 cases pregnant's height and weight at the 13th week of gestation and before delivery were measured. According to the formula, corresponding with BMI were calculated. From the 13 th week to before delivery, total of BMI increase and average of it per week were obtained. The follow-up and compared the pregnancy out comes of whose BMI were different increase status. Results Among the pregnant women whose BMI>23.7 at the 13th week, the incidence of mild and severe pregnancy induced hypertension(PIH) was more than BMI≤23.7( P <0.01) . The pregnant women with mild and severe PIH had a more average of BMI increase per week after the 13 th week(0.218±0.049). There was a significant different compared with the control group(0.186±0.045)( P <0.05); Among those whose total BMI increase was over 6 after the 13th week,the incidence of fetal macrosmia, high risk newborn and sesarean section because of prolonged labor and cephalo-pilvic disproportion was more. It was compared with other groups which was under 6, the different was significant( P <0.01, P <0.05). Conclusion Our study indicate that at the 13th week of gestation BMI>23.7 it may be a predictor for mild and severe PIH. To improve pregnancy outcome, it is a valuable work to direct proper foods and movements so that avoiding more increase of BMI during the gestation
