广州市12岁儿童恒牙龋病影响因素分析

Correlative Factors of Caries of 12-year-old Children in Guangzhou

目的研究广州市12岁儿童恒牙龋病状况及其影响因素。方法采用多阶段、分层、等容量、随机抽样的方法,抽取广州市12岁儿童720名,男女各半,进行口腔健康检查和口腔问卷调查。数据采用SPSS13.0统计软件处理,分析12岁儿童恒牙患龋率与影响因素的关系。结果广州市12岁儿童恒牙患龋率为30.1%,女生患龋率高于男生;龋均为0.57。经多因素Logistic逐步回归分析,发现是否独生子女、喝牛奶或酸奶的频率、是否听说过含氟牙膏这3个因素与12岁儿童恒牙龋病显著关联(P<0.05)。结论非独生子女、没有听说过含氟牙膏是危险因素(OR>1),儿童恒牙龋病概率大;喝奶频率高是保护因素(OR<1),这些儿童恒牙龋病概率小。
