To establish age-standardized charts of weight gain for term twin pregnancies in Southeast China.
We designed a retrospective study on data from women pregnant with twins, a gestational age beyond 36 weeks and an average weight ≥ 2500 g. We established hierarchical linear regression models to express gestational weight gain patterns.
We analyzed data from 884 women pregnant with twins (151 underweight, 597 normal weight, and 136 overweight). Our final models fit the crude weight measurement data well. The means of weight gain generally decreased as the pre-pregnancy BMI increased. For each BMI category, the mean weight gains increased with the gestational age and the standard deviation increased slightly. The mean weight gains were 18.82 ± 6.73, 18.53 ± 6.74, and 16.97 ± 6.95 kg at 37 weeks in underweight, normal weight, and overweight women, respectively.
The weight gain chart can be used to estimate maternal weight gain to be gestational age-standardized z scores by pre-pregnancy BMI and may serve as an innovative tool for perinatal care providers to guide the weight gain of women pregnant with twins.
建立中国东南部足月双胎妊娠体重增长的年龄标准化图表。
我们设计了一项回顾性研究，对孕龄超过 36 周且平均体重≥2500 克的双胎妊娠妇女的数据进行分析。我们建立了分层线性回归模型来表达妊娠体重增加模式。
我们分析了 884 名双胎妊娠妇女（151 名体重不足、597 名体重正常和 136 名超重）的数据。我们的最终模型很好地拟合了原始体重测量数据。体重增加的平均值通常随着孕前 BMI 的增加而降低。对于每个 BMI 类别，体重增加的平均值随着孕龄的增加而增加，标准差略有增加。在孕 37 周时，体重不足、体重正常和超重妇女的体重平均增加分别为 18.82±6.73、18.53±6.74 和 16.97±6.95kg。
体重增长图表可用于估计按孕龄标准化的孕前 BMI 产妇体重增长，可作为围产期护理提供者的创新工具，指导双胎妊娠妇女的体重增长。
