【摘要】:目的探討上海地區(qū)產(chǎn)婦孕期體重增長的適宜范圍及其與出生體重之間的關(guān)系。方法收集上海交通大學(xué)醫(yī)學(xué)院附屬仁濟醫(yī)院產(chǎn)科和上海市長寧區(qū)婦幼保健院產(chǎn)科分娩的自然妊娠、單胎、足月產(chǎn)產(chǎn)婦資料。采集孕婦自身指標(年齡、孕周、文化程度、身高、孕前體重、分娩前體重、受孕方式、產(chǎn)次、既往疾病史)和胎兒指標(出生孕周、分娩方式、胎兒性別、出生體重、出生身長)。體質(zhì)指數(shù)(body mass index,BMI)=體重(kg)/身高(m)2。孕婦妊娠前BMI≥24.0 kg/m2為超重,18.4 kg/m2為低體重。足月分娩胎兒出生體重4 000 g為巨大兒。結(jié)果共收集1 103人產(chǎn)婦納入本研究(低體重組192人、正常體重組761人、超重組150人)。巨大兒總發(fā)生率為6.3%。隨著產(chǎn)婦年齡的增加,BMI也逐步升高。低體重組和正常體重組孕期體重增長明顯高于超重組產(chǎn)婦,前兩組之間無明顯差異低體重組(15.4±4.3)kg、正常體重組(15.5±5.1)kg、超重組(13.0±6.0)kg;雖然超重組產(chǎn)婦體重增長較少,但胎兒出生體重卻明顯高于其他2組產(chǎn)婦低體重組(3 261.2±341.9)g、正常體重組(3 387.9±383.7)g、超重組(3 469.6±408.2)g。低體重組孕婦自然分娩率最高(57.8%),其次為正常體重組(48.6%),超重組最低(40.0%)。采用四分位數(shù)方法,孕前低體重組和正常體重組的孕期體重適宜增長范圍為12.0~18.5 kg,超重組則為9.0~16.0 kg。二項Logistic回歸分析顯示孕前BMI和孕期體重增長是巨大兒發(fā)生的危險因素。結(jié)論孕前BMI和孕期體重增長是巨大兒發(fā)生的危險因素。控制孕前BMI和孕期體重增長才能有效降低巨大兒的發(fā)生。
[Abstract]:Objective to explore the appropriate range of maternal weight gain during pregnancy and its relationship with birth weight in Shanghai area. Methods the data of natural pregnancy, single child and term delivery in obstetrics of Renji Hospital affiliated to Shanghai Jiaotong University Medical College and Changning District Maternal and Child Health Hospital were collected. Maternal parameters (age, gestational age, education, height, weight before pregnancy, weight before delivery, mode of conception, time of delivery, history of previous disease) and fetal indicators (gestational age, delivery mode, fetal sex, birth weight) were collected.
