项目摘要

To identify appropriate prenatal weight gain ranges associated with least obstetric complications, a retrospective cohort study was conducted with 733 healthy women with a singleton pregnancy. Pregnant women were' grouped by pre-pregnant body mass index (BMI) according to the definitions of Japan Society of Obstetrics and Gynecology, lean (BMI<18.0), medium (18≦BMI<24.0), and overweighed women (BMI≦24.0). In each women group, total prenatal weight gain was grouped according to 10th, 25th, 50th, 75th, and 90th percentile values. In lean women, small for gestational age(SFG)infants risk was related to weight gain less than 75th percentile (12.6 kg) and post-term pregnancy (≧90th of gestational length, 287days)risk was related to weight gain equal or more than 90th percentile (14.7kg). In medium women, SFG and low birth weight (<2,500g)infants risk was related to weight gain less than 10th percentile (6 kg) and prolonged labor risk was related to weight gain equal or more than 90th percentile (14.0kg). In overweighed women, large for gestational age (LGA)infants risk was related to weight gain equal or more than 50th percentile (7.1 kg). In conclusions, optimal prenatal weight gains are 12.6≦and <14.7 kg for lean, 6.0≦and <14.0 kg for medium, and <7.1kg for overweighed women.

为了确定与最少产科并发症相关的适当产前体重增加范围，对 733 名单胎妊娠的健康孕妇进行了一项回顾性队列研究，根据日本协会的定义，按孕前体重指数 (BMI) 进行分组。妇产科，瘦（BMI<18.0）、中等（18≤BMI<24.0）和超重女性（BMI≤24.0）。在每个女性组中，总产前体重增加根据第 10、25、50、75 和 90 个百分位值进行分组。在瘦女性中，小于胎龄 (SFG) 婴儿的风险与体重增加低于 75 个百分位 (12.6) 相关。 kg）和足月妊娠（≥妊娠长度的90分之一，287天）风险与体重增加相关，等于或超过在中等女性（14.7 公斤）中，SFG 和低出生体重（<2,500 克）婴儿的风险与体重增加低于 10 分位（6 公斤）相关，而延长分娩风险与体重增加等于或大于 90 相关。在超重女性中，大于胎龄 (LGA) 婴儿的风险与体重增加等于或超过第 50 个百分位有关。 (7.1公斤) 总之，瘦女性的最佳产前体重增加为12.6≤且<14.7公斤，中等体重的最佳产前体重增加为6.0≤且<14.0公斤，超重女性的最佳产前体重增加为<7.1公斤。
