本研究的目的是评估肥胖和妊娠期体重增加对早产亚型风险的影响，因为对这些相关性知之甚少。该研究包括丹麦国家出生队列中的62167名妇女，这些妇女自我报告了有关孕前体重指数（BMI）和妊娠期体重增加的信息。关于自发性早产伴或不伴早产胎膜早破（PPROM）和引产早产的信息来自国家登记册。采用考克斯回归分析研究孕前BMI和妊娠期体重增加与早产亚型的关系，肥胖妇女（BMI >= 30）PPROM和早产的粗风险高于正常体重妇女（18.5
The aim of the present study was to assess the impact of obesity and gestational weight gain on the risk of subtypes of preterm birth, because little is known about these associations. The study included 62 167 women within the Danish National Birth Cohort for whom self-reported information about prepregnancy body mass index (BMI) and gestational weight gain was available. Information about spontaneous preterm birth with or without preterm premature rupture of membranes (PPROM) and about induced preterm deliveries was obtained from national registers. Cox regression analyses were used to examine associations of prepregnancy BMI and gestational weight gain with subtypes of preterm birth.The crude risks of PPROM and of induced preterm deliveries were higher in obese women (BMI >= 30) than in normal-weight women (18.5
