孕妇牙周健康状况与早产的相关性研究

摘要

Objective To survey on periodontal status of pregnant women and pregnant outcome,and to explore its possible relation-ship between periodontal infection and preterm birth.Methods 674 pregnant women were selected in Wuxi Maternal and Child Health-Care Hospital during 2012 January-December.Women were given periodontal examination.OHI-S,SBI,PD and CAL were recor-ded and pregnant outcome was tracked.The result was analyzed with chi-square test,t test and Spearman correlation analysis.Results①Periodontitis prevalence of preterm women (36.1%)was higher than that of full-term pregnant women (21.4%).There was a sig-nificant difference in gestational age and birth weight between the two groups (P<0.01 );②OHI-S,SBI,PD,CAL of preterm group were higher than full-term pregnancy group (P<0.05);③Maternal periodontal index of OHI-S,PD,CAL and gestational age was neg-atively correlated (P<0.05).Conclusions There is a correlation between maternal periodontal infection and preterm birth.Periodon-titis among pregnant women is a risk factor for preterm birth.We must pay more attention to oral health care of these pregnant women.%目的：通过调查孕妇牙周状况和分娩结局，探讨牙周感染与早产的关系。方法选择2012年在无锡市妇幼保健院进行孕检孕妇674名，进行临床牙周检查，记录简化口腔卫生指数（OHIS）、龈沟出血指数（SBI）、探诊深度（PD）和临床附着丧失（CAL），追踪妊娠结局，运用卡方检验，t检验和 Spearman检验的统计学方法对数据进行分析。结果①早产组孕妇牙周炎患病率（36．1％）高于足月妊娠组（21．4％）；②早产组孕妇牙周指标 OHI S、SBI、PD、CAL 均高于足月妊娠组（P #0．05）；③孕妇牙周指标 OHIS、PD、CAL与分娩孕周呈负相关关系（P #0．05）。结论孕妇牙周感染与早产之间存在着相关性，可能是早产的危险因素之一，应做好孕期口腔健康教育。
