OBJECTIVE
To examine the amount of weight women with eating disorders [anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED)] gained during pregnancy and to evaluate the adequacy of total weight gain.
METHOD
Data from the Norwegian Mother and Child Cohort Study were used in a cross-sectional manner, n = 35,148. Descriptive statistics and Generalized Estimating Equations to calculate the relative risk estimates were employed.
RESULTS
Mean gestational weight gain for the entire sample was 2.5 kg at 17.0-20.1 weeks gestation, 9.3 kg at 27.4-29.7 weeks gestation and 15.0 kg at delivery. Women with BN and BED gained significantly more weight on average than those with no eating disorders at each time point. Women with AN had a lower risk (AOR = 0.65 (0.24, 1.72) of gaining inadequately while women with BN and BED were more likely to gain excessively, AOR = 1.09 (1.01, 1.18) and 1.11 (1.08, 1.14), respectively.
DISCUSSION
The pattern of weight gain identified for each eating disorder subtype may help explain the birth outcomes of women with eating disorders.
目的
探讨患有饮食障碍（神经性厌食症（AN）、神经性贪食症（BN）和暴食障碍（BED））的女性在怀孕期间体重增加的幅度，并评估总增重是否充足。
方法
本研究采用挪威母婴队列研究的数据进行横断面研究，n=35148。采用描述性统计和广义估计方程来计算相对风险估计值。
结果
整个样本的平均妊娠增重为：妊娠 17.0-20.1 周时为 2.5 公斤，妊娠 27.4-29.7 周时为 9.3 公斤，分娩时为 15.0 公斤。与无饮食障碍的女性相比，患有 BN 和 BED 的女性在每个时间点的平均体重增加量明显更多。患有 AN 的女性增重不足的风险较低（AOR=0.65（0.24，1.72），而患有 BN 和 BED 的女性则更有可能过度增重，AOR 分别为 1.09（1.01，1.18）和 1.11（1.08，1.14）。
讨论
每种饮食障碍亚型的体重增加模式可能有助于解释饮食障碍女性的分娩结局。
