To look for associations between pregnancy outcomes and prepregnancy body mass index and gestational weight gain among Han women from Shenyang province, China.
A total of 2586 women were distributed across 4 prepregnancy categories according to the Chinese classification of body mass index, and to 4 end-of-pregnancy categories according to median weekly gestational weight gain.
The risks for gestational hypertension, pre-eclampsia, gestational diabetes, and preterm premature rupture of membranes were higher for those who were overweight or obese before becoming pregnant (P<0.05). Moreover, a gestational weight gain of 0.50 kg per week or greater was associated with a higher risk for gestational hypertension, preterm premature rupture of membranes, and fetal macrosomia (P<0.05). Women in the highest quartile for weight gain (>or=0.59 kg per week) were at higher risk for pre-eclampsia (P<0.05).
A high prepregnancy body mass index and excessive gestational weight gain were associated with increased risks for adverse pregnancy outcomes.
寻找中国辽宁省汉族女性妊娠结局与孕前体重指数和妊娠期体重增加之间的关联。
根据中国体重指数分类，将 2586 名女性分为 4 个孕前类别，并根据中位每周妊娠期体重增加分为 4 个孕期末期类别。
超重或肥胖的女性在怀孕前患妊娠高血压、先兆子痫、妊娠糖尿病和早产胎膜早破的风险更高（P<0.05）。此外，每周增重 0.50 公斤或以上与妊娠高血压、早产胎膜早破和胎儿巨大儿的风险增加有关（P<0.05）。体重增加最高四分位（>或=0.59 公斤/周）的女性患先兆子痫的风险更高（P<0.05）。
高孕前体重指数和过多的妊娠期体重增加与不良妊娠结局的风险增加有关。
