Maternal health in pregnancy and birth outcomes were compared between pre- and post-Varzaghan earthquake.
In this retrospective descriptive study, before and after the earthquake, 550 and 450 women were enrolled respectively. Neonatal weight, height, and head circumference, as well as maternal weight gain and hemoglobin (Hb) levels were obtained using medical records at health centers. Chi-square test and Independent t-test were used to analyze differences in pregnancy outcomes. A -value less than 0.05 was considered significant.
A significant increase in inadequate gestational weight gain (44.1% vs 58.9%) was observed ( = 0.043) before and after the earthquake. The mean hemoglobin level in the first trimester before the earthquake was significantly higher than after the earthquake ( = 0.001). Before-after earthquake comparisons showed that the mean birth weight, birth height, and birth head circumference were decreased significantly ( < 0.05). In addition, the rates of preterm birth (18.91% vs 10.90%), abortion (17.11% vs 10.54%), and stillbirth (3.78% vs 1.82%) were increased significantly after the earthquake ( < 0.05).
Earthquake causes inadequate gestational weight gain and decreased hemoglobin levels, which lead to adverse birth outcomes. More longitudinal and well-designed studies are desired to investigate the longitudinal consequences of disasters on susceptible groups.
比较瓦尔扎甘地震前后的孕产妇孕期健康状况及分娩结局。
在这项回顾性描述性研究中，地震前后分别纳入了550名和450名女性。通过健康中心的医疗记录获取新生儿体重、身高、头围，以及孕产妇体重增加情况和血红蛋白（Hb）水平。采用卡方检验和独立样本t检验分析妊娠结局的差异。P值小于0.05被认为具有统计学意义。
观察到地震前后孕期体重增加不足的情况显著增加（44.1%对58.9%）（P = 0.043）。地震前孕早期的平均血红蛋白水平显著高于地震后（P = 0.001）。地震前后比较显示，平均出生体重、出生身高和出生头围均显著下降（P < 0.05）。此外，地震后早产率（18.91%对10.90%）、流产率（17.11%对10.54%）和死产率（3.78%对1.82%）均显著上升（P < 0.05）。
地震导致孕期体重增加不足和血红蛋白水平下降，进而导致不良分娩结局。需要更多纵向且设计良好的研究来调查灾害对易感人群的长期影响。
