Although eating disorder symptoms generally decrease in pregnancy, loss of control eating (LOC), defined by the consumption of food accompanied by a sense of being unable to control what or how much is eaten, often persists and may develop in pregnancy. Given that LOC is associated with higher weight status and psychological distress, it is important to understand factors associated with perinatal LOC. Although childhood traumatic events have been linked to LOC in non-pregnant women, the impact of such events on LOC in pregnancy is unknown. Accordingly, the present study aimed to examine the association between a history of childhood traumatic events and LOC prior to and during pregnancy among a community sample of pregnant women with overweight or obesity. Pregnant women (N = 244) were enrolled in a longitudinal study. Women completed interviews between 12 and 20 weeks gestation to document a history of childhood traumatic events and the presence of LOC in the three months prior to and during their current pregnancy. Women were assessed for LOC monthly for the remainder of pregnancy. Results from a multinomial regression model showed that women with a history of childhood traumatic events had higher odds of engaging in LOC both prior to and during pregnancy (OR = 2.52, 95% CI [1.13, 5.64], p = 0.02) but not during pregnancy only (OR = 1.58, 95% CI [0.87, 2.89], p = 0.39). These findings indicate that women with a history of childhood traumatic events may be especially prone to LOC in the months prior to conception that continues throughout pregnancy.

虽然饮食失调症状通常在怀孕期间减少，但饮食失控 (LOC) 的定义是进食食物并伴有无法控制吃什么或吃多少的感觉，通常会持续存在并可能在怀孕期间发展。鉴于 LOC 与较高的体重状态和心理困扰有关，了解与围产期 LOC 相关的因素很重要。尽管儿童创伤事件与非孕妇的 LOC 相关，但此类事件对妊娠期 LOC 的影响尚不清楚。因此，本研究旨在检查超重或肥胖孕妇社区样本中儿童创伤事件史与怀孕前和怀孕期间 LOC 之间的关联。孕妇（N = 244) 参加了一项纵向研究。女性在妊娠 12 到 20 周之间完成了采访，以记录儿童创伤事件的历史以及在当前怀孕前三个月和当前怀孕期间 LOC 的存在。在怀孕的剩余时间内，每月对妇女进行 LOC 评估。多项回归模型的结果显示，有童年创伤事件史的女性在怀孕前和怀孕期间参与 LOC 的几率更高（OR = 2.52, 95% CI [1.13, 5.64], p  = 0.02），但在怀孕期间则不然仅怀孕（OR = 1.58, 95% CI [0.87, 2.89], p  = 0.39）。这些研究结果表明，有童年创伤事件史的女性在受孕前几个月可能特别容易发生 LOC，并持续到整个怀孕期间。
