【摘要】 目的了解烟台市12～15岁学生恒牙患龋情况及社会行为因素,为预防学生龋齿提供参考依据。方法采用分层、整群、等容量随机抽样的方法,抽取代表烟台地域特征的5个县市区,每个县市区抽取3所中学,按照初一、初二、初三、初四(12～15岁年龄组)每个年龄组各选取男女32人,进行口腔健康检查,并进行问卷调查。结果共获得有效问卷3812份,1912名学生发生恒牙患龋,患龋率为50.16%,龋均为1.29±1.89;其中,女生患龋率为54.12%(1055/1949)高于男生患龋率为46.00%(857/1863)。logistics回归分析显示,女性学生(OR=1.42,95%CI=1.24～1.64)、每周两次以上食用甜点心和糖果(OR=1.30, 95%CI=1.04～1.62)、非独生子(OR=1.17, 95%CI=1.02～1.35)是学生患龋齿的危险因素,家住城区、每天坚持刷牙以及对于口腔知识的认知(吃糖可导致龋齿、口腔健康可能会影响全身健康)是保护因素。结论不良的饮食、生活习惯是恒牙患龋的危险因素。应加强学生口腔健康教育工作,提高学生口腔保健知识水平,更好的预防和减少龋齿。更多还原
