To determine optimal gestational weight gain (GWG) for the Chinese population.Live singleton deliveries at the largest maternal & childcare hospital in northwest China from 2010 to 2012 were analyzed retrospectively. Multivariable logistic regression analysis was conducted to determine the lowest aggregated risk of interested perinatal outcomes based on Chinese adult body mass index (BMI) categories.Eight thousand eight hundred seventy enrolled parturients were divided into 4 groups according to their prepregnancy BMI: underweight (21.31%, BMI < 18.5 kg/m2), normal weight (67.81%, 18.5 kg/m2 ≤ BMI < 24 kg/m2), overweight (8.99%, 24 kg/m2 ≤ BMI < 28 kg/m2 and obese (1.89%, BMI ≥ 28 kg/m2). The optimal GWG values for the above 4 groups were 16.7 kg (GWG range, 12.0-21.5), 14.5 kg (9.5-19.5), 11.5 kg (7.0-16.5), and 8.0 kg (5.0-13.0). The rates of inadequate, optimal and excessive GWG in present study were 6.14% (545), 62.34% (5529), and 31.52% (2796) respectively, which were significantly different from those of the 2009 Institute of Medicine recommendation (χ2 = 1416.05, Pinteraction < 0.0001).Wider optimal GWG ranges than those recommended by Institute of Medicine were found in our study, and our proposed criteria seems to be practical to the Chinese population.
为了确定中国人的最佳妊娠体重增加（GWG）。回顾性分析了 2010 年至 2012 年中国西北地区最大的母婴保健医院的单胎分娩。基于中国成人 BMI 类别，采用多变量逻辑回归分析确定感兴趣的围产期结局的最低综合风险。根据孕前 BMI 将 8870 名产妇分为 4 组：低体重组（21.31%，BMI<18.5kg/m2）、正常体重组（67.81%，18.5kg/m2≤BMI<24kg/m2）、超重组（8.99%，24kg/m2≤BMI<28kg/m2）和肥胖组（1.89%，BMI≥28kg/m2）。上述 4 组的最佳 GWG 值分别为 16.7kg（GWG 范围 12.0-21.5）、14.5kg（9.5-19.5）、11.5kg（7.0-16.5）和 8.0kg（5.0-13.0）。本研究中，GWG 不足、合适和过多的发生率分别为 6.14%（545 例）、62.34%（5529 例）和 31.52%（2796 例），与 2009 年美国医学研究所的建议明显不同（χ2=1416.05，Pinteration<0.0001）。与美国医学研究所的建议相比，本研究发现更宽的 GWG 范围，并且我们提出的标准似乎对中国人群实用。
