目的：评估怀孕期间经历大洪水对胎儿生长和妊娠时间的影响，并考虑与洪水相关的菌株如何导致这些影响。方法：红河怀孕项目是一项前瞻性研究，在 2009 年北达科他州法戈市红河历史性的顶峰出现后立即进行了 3 个月。年龄至少 18 岁、单胎宫内妊娠的怀孕社区居民参与了这项研究 (N = 169)。分析检查了出生体重和妊娠时长是否与距洪水的居住距离和洪峰时的孕龄有关。结果：对于波峰期间妊娠早期的妊娠（-1 SD = 12 周），出生体重随着距洪水距离的缩短而下降（-42.29 g/mi，p < .01）。对于妊娠高峰期较晚的妊娠（+1 SD = 26 周），距离与出生体重无关 (p > .10)。双顶生长轨迹显示，洪水到达顶峰后生长有所下降，但仅限于怀孕早期的女性。然而，与洪水相关的各种压力和一般应力或应变的测量并不能解释这些影响。妊娠时间与距洪水的距离或发生的时间无关。结论：在家附近经历大洪水的妊娠早期孕妇，由于胎儿生长速度下降，面临着新生儿出生体重较低的风险。在灾后迅速开展的调查中，这种效应的机制值得进一步关注。
Objective: To assess the impact of experiencing a major flood during pregnancy on fetal growth and length of gestation, and to consider how flood-related strains might contribute to these effects. Method: The Red River Pregnancy Project was a prospective study carried out for 3 months immediately after the historic 2009 crest of the Red River in Fargo, North Dakota. Pregnant community residents who were at least 18 years old with a singleton, intrauterine pregnancy participated in the study (N = 169). Analyses examined if birth weight and length of gestation were associated with residential distance from flooding and gestational age at time of the flood crest. Results: For pregnancies earlier in gestation during the crest (-1 SD = 12 weeks), birth weight decreased as distance from flooding decreased (-42.29 g/mi, p < .01). For pregnancies later in gestation at crest (+1 SD = 26 weeks), distance was not associated with birth weight (p > .10). Biparietal growth trajectories showed a decrease in growth after the crest of the flood but only for women early in pregnancy. However, various measures of flood related and general stress or strain did not explain these effects. Length of gestation was not associated with distance from or the timing of the flood. Conclusions: Pregnant women in the first trimester who experience a major flood near their homes are at risk of having lower birth weight neonates due to a reduction in fetal growth. The mechanisms of this effect deserve further attention in rapidly mounted investigations after disaster.
