AIMS
To determine the effect of increasing maternal body mass index (BMI) during pregnancy on maternal and infant health outcomes.
METHODS
The South Australian Pregnancy Outcome Unit's population database, 2008 was accessed to determine pregnancy outcomes according to maternal BMI. Women with a normal BMI (18.5-24.9 kg/m(2) ) formed a reference population, to which women in other BMI categories were compared utilising risk ratios and 95% confidence intervals.
RESULTS
Overweight and obese women had an increased risk of gestational diabetes, hypertension and iatrogenic preterm birth. Labour was more likely to be induced, and the risk of caesarean birth was increased. Infants were more likely to require resuscitation at birth and to have birth weight in excess of 4 kg. The risk increased with increasing maternal BMI.
CONCLUSIONS
There is a well-documented increased risk of maternal and perinatal health complications for women who are overweight or obese during pregnancy.
目的
确定孕期孕妇体重指数（BMI）增加对母婴健康结局的影响。
方法
利用南澳大利亚妊娠结局单位2008年的人口数据库，根据孕妇BMI确定妊娠结局。BMI正常（18.5 - 24.9kg/m²）的女性构成参考人群，将其他BMI类别的女性与该参考人群进行比较，计算风险比和95%置信区间。
结果
超重和肥胖女性患妊娠期糖尿病、高血压和医源性早产的风险增加。引产的可能性更大，剖宫产风险增加。婴儿出生时更有可能需要复苏，且出生体重超过4kg。风险随孕妇BMI增加而升高。
结论
有充分记录表明，孕期超重或肥胖的女性发生母婴健康并发症的风险增加。
