目的探讨孕早期牙龈出血与妊娠相关焦虑症状的关联。方法选取2008年10月—2010年10月在安徽省马鞍山市4家市级医疗卫生机构首次进行孕期体检的5 084名孕妇为研究对象,采用问卷调查的方法收集资料,使用χ2检验和多因素非条件logistic回归模型对数据进行分析。结果早上醒来口腔出血或有血腥味、咬硬物时牙齿出血和刷牙时牙齿出血的检出率分别为19.2%、17.8%和52.2%;牙龈有轻度炎症和中-重度炎症者分别为24.4%和8.9%;调整孕妇年龄等变量后,早上醒来口腔出血或有血腥味1～2次(OR=1.33,95%CI=1.10～1.61)和≥3次(OR=1.83,95%CI=1.44～2.31)、咬硬物时牙齿出血1～2次(OR=1.40,95%CI=1.17～1.67)和≥3次(OR=1.62,95%CI=1.18～2.23)、刷牙时牙齿出血≥3次(OR=1.40,95%CI=1.20～1.64)以及牙龈指数显示中、重度炎症(OR=1.37,95%CI=1.10～1.71)均能增加孕早期妊娠相关焦虑发生的风险。结论牙龈出血在孕妇中普遍存在,如果处理不当,将对孕妇心理健康产生一定影响。 Objective To explore the association between gingival bleeding in early pregnancy and pregnancy-related anxiety symptoms. Methods From October 2008 to October 2010, 5 084 pregnant women, who were the first pregnant women in 4 municipal health institutions in Ma’anshan City, Anhui Province, were selected as the study subjects. Data were collected by questionnaire, using χ2 test and multiple factors Non-conditional logistic regression model was used to analyze the data. Results In the morning wake up oral bleeding or bloody smell, biting hard objects when the teeth bleeding and tooth brushing teeth bleeding rate was 19.2%, 17.8% and 52.2%; gums with mild inflammation and moderate-severe inflammation were (OR = 1.33, 95% CI = 1.10 ~ 1.61) and ≥3 times (OR = 1.83, 95% CI, (OR = 1.40, 95% CI = 1.17-1.67) and ≥3 times (OR = 1.62, 95% CI = 1.18-2.23) when brushing teeth Dental bleeding ≥3 (OR = 1.40, 95% CI = 1.20-1.64) and gingival index showed moderate and severe inflammation (OR = 1.37, 95% CI = 1.10-1.71) increased the risk of pregnancy-related anxiety . Conclusion Gingival bleeding is widespread in pregnant women, if not properly handled, will have a certain impact on the mental health of pregnant women.
