To determine the effects of displacement due to flooding during pregnancy on birth outcomes (infant birth weight and gestational age) and the moderating effect of perceived social support on the relationship between displacement and birth outcomes.
A descriptive, longitudinal study.
A university-affiliated hospital in Pathum Thani, Thailand.
Pregnant women (N = 175) in the third trimester that had uncomplicated pregnancies and no history of mental illness.
During pregnancy, the participants completed standardized measurements of depression symptoms, perceived social support, and questionnaires concerning the effect of the flood. After giving birth, infant birth weight and gestational age at birth were retrieved from delivery records.
Seventy percent (n = 123) of the participants experienced displacement during the flood. The displaced women had a mean infant birth weight of 175 grams less than that of the nondisplaced women, t(173) = -2.38, p = .02, whereas infant gestational age was not different. Displacement and other variables explained approximately 8% of the variance in infant birth weight. The interaction term between displacement and perceived social support was statistically significant and additionally explained the variance in infant birth weight, F(6, 168) = 3.24, p = .005.
Being displaced during pregnancy due to a natural disaster affected fetal growth rather than length of gestation. Health care providers should closely monitor maternal weight gain and fetal growth of pregnant women who experience displacement. Among the displaced women, social support was associated with higher infant birth weight; therefore, high levels of perceived social support may be protective for pregnant women who experience stressful events such as displacement from flooding.
确定孕期因洪水导致的流离失所对出生结局（婴儿出生体重和孕周）的影响，以及感知到的社会支持对流离失所与出生结局之间关系的调节作用。
一项描述性纵向研究。
泰国巴吞他尼府的一家大学附属医院。
175名孕晚期孕妇，她们孕期情况正常且无精神疾病史。
在孕期，参与者完成了抑郁症状、感知到的社会支持的标准化测量，以及有关洪水影响的问卷调查。分娩后，从分娩记录中获取婴儿出生体重和出生时的孕周。
70%（n = 123）的参与者在洪水期间经历了流离失所。流离失所的女性所生婴儿的平均出生体重比未流离失所的女性所生婴儿轻175克，t(173) = -2.38，p = .02，而婴儿孕周没有差异。流离失所及其他变量解释了婴儿出生体重约8%的变异。流离失所与感知到的社会支持之间的交互项具有统计学意义，并且额外解释了婴儿出生体重的变异，F(6, 168) = 3.24，p = .005。
孕期因自然灾害而流离失所影响胎儿生长而非孕周长度。医疗保健提供者应密切监测经历流离失所的孕妇的体重增加和胎儿生长情况。在流离失所的女性中，社会支持与较高的婴儿出生体重相关；因此，高水平的感知到的社会支持可能对经历诸如因洪水而流离失所等压力事件的孕妇具有保护作用。
