北京地区母亲牙周状况与早产低出生体重新生儿的关系

目的 初步评价北京地区人群中母亲牙周状况与早产低出生体重新生儿的关系.方法 对2004年1月至2005年12月在北京市4家医院分娩的83例早产低体重新生儿(preterm low birth weight,PLBW)的母亲(PLBW组)以及44名正常新生儿(normal birth weight,NBW)的母亲(NBW组)进行牙周临床指标的检查.所有受检者均全身健康.检查指标包括:菌斑指数(plaque index,PLI)、探诊深度(probing depth,PD)、临床附着丧失(attachment loss,AL)和出血指数(bleeding index,BI).结果 中度慢性牙周炎及侵袭性牙周炎母亲发生PLBW的风险是牙龈炎或轻度慢性牙周炎母亲的4.26倍.PLBW组与NBW组PD≥4 mm位点率(分别为8.1%和6.9%)、AL≥2 mm 位点率(分别为12.8%和6.1%)和BOP(+)位点率(分别为70.4%和66.9%),PLBW组均显著高于NBW组(P值分别小于0.01、0.001、0.01).结论 本组人群中母亲的牙周状况与PLBW之间可能存在关联,较差的牙周状况可能是发生PLBW的危险因素之一.

Association between mother's periodontal status and preterm low birth weight in Beijing

Objective To investigate the possible association between mother's periodontal status and preterm low birth weight(PLBW)in Beijing.Methods The periodontal status of 83 women who bore a preterm low birth weight infant(PLBW group)and 44 women who bore a normal birth weight infant(NBW group)within two years in four hospitals in Beijing were evaluated.These women were all generally healthy.The clinical periodontal parameters including plaque index(PLI),probing depth(PD),attachment loss (AL)and bleeding index(BI)recorded.Results The percentages of PD≥4 mm sites,AL≥2 mm sites and BOP(+)sites in two groups were 8.1%vs 6.9%,12.8%vs 6.1%and 70.4%vs 66.9%,respectively,which showed significantly higher in PLBW group than in NBW group(P＜0.01,P＜0.001,P＜0.01 ).Conclusions There was possible association between mother's periodontal status and preterm low birth weight in the investigated area.Poor periodontal status may be one of the risk factors of PLBW.
