目的调查分析有家庭成员在汶川地震中伤亡的再生育夫妇自然流产的相关危险因素。方法通过回顾性问卷调查方式,2008年9月2011年3月收集整理44对震后有自然流产的再生育夫妇基本资料和自然流产相关危险因素,分析该类人群震后自然流产危险因素特点。结果自然流产发生率占总妊娠比例的22.9%,11.1%的女性出现了震后月经改变,有人流史妇女与无人流史妇女震后月经改变率比较,差异无统计学意义(χ2=0.58,P>0.05)。结论震后女性易发生月经改变,地震后再生育夫妇的自然流产发生率显著高于正常人群中的自然流产发生率,环境、高龄等因素可能是该人群自然流产高发的主要危险因素。
Objective To investigate and analyze the related risk factors of spontaneous abortion among family members who have been killed and wounded during the Wenchuan earthquake. Methods By means of retrospective questionnaire, we collected and analyzed 44 basic information on spontaneous abortion couples and spontaneous abortion-related risk factors after the earthquake in September 2008 and March 2011, and analyzed the characteristics of the risk factors of spontaneous abortion after such quake. Results The incidence of spontaneous abortion accounted for 22.9% of the total pregnancies, while 11.1% of women experienced menstrual changes after menstruation. There was no significant difference in the rate of menstruation between women with abortion and those without abortion (χ2 = 0.58, P> 0.05). Conclusions The occurrence of menstrual changes is easy to occur in women after earthquake. The incidence of spontaneous abortion of couples with reproductive life after earthquake is significantly higher than that of normal population. The factors such as environment and age may be the main risk factors for high spontaneous abortion in this population.
