目的：研究模式的母亲体重增加使用母亲的特点和妊娠outcome.Methods：我们使用的母亲体重数据测量前瞻性的所有交付之间的1980-1990年在加州大学，旧金山弗朗西斯科。采用分段线性回归方法估计孕妇在每个孕期的体重增长率。双变量技术被用来检查产妇每三个月的体重增加和产妇的特征和妊娠结局之间的关联。我们还采用多元回归分析，以检查产妇的特点和三个月的weight gains.Results之间的关系：体重数据至少有一个三个月的10,418名妇女。平均体重增加率（kg/周）在孕早期最低（0.169 +/- 0.268，n = 7587），在孕中期达到峰值（0.563 +/- 0.236，n = 8000），在孕晚期略有放缓（0.518 +/- 0.234，n = 10，052）。母亲身高、高血压、剖宫产和胎儿大小与每个妊娠期的增重率呈正相关，但孕前体型、年龄、产次、吸烟状况、种族和糖尿病与增重的相关性不同，这取决于检查的妊娠期。每三个月的体重增加的最重要的产妇预测因素是年龄和亚洲种族，种族在第一个三个月;孕前体重，奇偶校验，身高在第二个;和高血压，年龄，奇偶校验在third.Conclusion：产妇体重增加每三个月与一些产妇的特征和妊娠结局，这些关系各不相同，根据这三个月正在检查。
Objective: To examine the pattern of maternal weight gain using maternal characteristics and pregnancy outcome.Methods: We used maternal weight data measured prospectively from all deliveries between 1980-1990 at the University of California, San Francisco. Piecewise linear regression was used to estimate the rate of maternal weight gain in each trimester. Bivariate techniques were used to examine associations between maternal weight gain per trimester and maternal characteristics and pregnancy outcomes. We also used multiple regression analysis to examine the relationship between maternal characteristics and trimester weight gain.Results: Weight data for at least one trimester were available for 10,418 women. The average rate of weight gain (kg/week) was lowest during the first trimester (0.169 +/- 0.268, n = 7587), peaked during the second trimester (0.563 +/- 0.236, n = 8000), and slowed slightly in the third trimester (0.518 +/- 0.234, n = 10,052). Maternal height, hypertension, cesarean delivery, and fetal size correlated positively with the rate of gain in each trimester, but pre-pregnancy body size, age, parity, smoking status, race-ethnicity, and diabetes were associated differently with gain, depending on which trimester was examined. The most important maternal predictors of weight gain per trimester were age and Asian race-ethnicity in the first trimester; pre-pregnancy body mass, parity, and height in the second; and hypertension, age, and parity in the third.Conclusion: Maternal weight gain per trimester is associated with a number of maternal characteristics and pregnancy outcomes, and these relationships vary according to which trimester is being examined.
