目的探讨妊娠期体重增加和产妇体重指数（BMI）之间的关联，越南妇女和风险提供一个婴儿太小或太大的胎龄。方法一个前瞻性的卫生设施为基础的研究，2989名越南孕妇在芽庄市在2007-2008年进行。使用三次logistic回归来调查感兴趣的关联。根据亚洲人群的体重百分位数，将婴儿分为胎龄体重类别。胎龄基于末次月经日期，并根据孕早期超声结果进行调整。结果BMI较低（= 23.0）的女性分别为26.1%、65.4%和8.5%。在这些BMI类别中，分娩小于胎龄儿的女性比例分别为18.1、10.0和9.4，平均妊娠期体重增加分别为12.5 kg（标准差：+/- 3.6）、12.2 kg（标准差：+/- 3.8）和11.5 kg（标准差：+/- 4.7）。在低BMI的妇女中，如果妊娠期体重增加，分娩小于胎龄儿的风险约为40%，
Objective To examine the association between gestational weight gain and maternal body mass index (BMI) among Vietnamese women and the risk of delivering an infant too small or too large for gestational age.Methods A prospective health-facility-based study of 2989 pregnant Vietnamese women was conducted in the city of Nha Trang in 2007-2008. Cubic logistic regression was used to investigate the association of interest. Infants were classified into weight-for-gestational-age categories according to weight centiles for the Asian population. Gestational age was based on the date of last menstrual period and adjusted by the results of first-trimester ultrasound.Findings BMI was low (= 23.0) in 26.1%, 65.4% and 8.5% of the women, respectively. In each of these BMI categories, the percentage of women who delivered infants too small for gestational age was 18.1, 10.0 and 9.4, respectively, and the mean gestational weight gain was 12.5 kg (standard deviation, SD: +/- 3.6), 12.2 kg (SD: +/- 3.8) and 11.5 kg (SD: +/- 4.7), respectively. Among women with low BMI, the risk of delivering an infant too small for gestational age ranged from approximately 40% if the gestational weight gain was
