孕妇牙周病与低体质量早产儿的关系

A preliminary study on the relationship between maternal periodontal disease and low weight of newborn

目的 探讨孕妇牙周病与低体质量早产儿（PLBI）的相关性。方法 调查200例产后4d孕妇。PLB1组：低体质量〈2500g或者伴有孕期〈37周、胎膜早破等妊娠不良情况（n=100）。对照组：新生儿低体质量〉2500g、正常分娩（n=100）。每例受试者均接受牙周检查。结果 LWN组牙周病明显重于对照组（P〈0.01）。200例孕妇牙周袋深度和牙龈指数与新生儿低体质量呈负相关（rGl=-0．37，P〈0．01；tPD=-0．19，P〈0．01） 结论 孕妇的牙周病与新生儿低体质量呈低度相关。

Objective To detect whether the maternal periodontal diseases COUld de associated With preterm low-birth weight infant（PLBI）. Methods A case-control study of 200 postpartum mothers was performed,preterm low-birth weight infant（PLBI） cases were confined to the mother with new born of less than 2500g and one or more of the following eonditious;gestational age 〈37 weeks, or early rupture of placental membrane（ n = 100）, Controls were normal birth with weight（NBW） 〉 2500g（ n = 100）. Each subject received a period on examination to determine the clinical indices. Results PLBW cases had significantly worse periodontal disease than the normal cases in GI and PD examination（ P 〈 0.01 ）. Simple correlation between GI ,PD and weight in 200 postpartum mothers was lower（ rGl = - 0.37, rPD = - 0.19）. Conclusion It needs further research for period on infection as one of the risk factors resulting in preterm low-birth weight infant.
