Confirmatory study on the regression equation for children dental behavior in Beijing

目的 检验既往研究获得的口腔诊疗中儿童行为表现预测回归方程的准确性,为该方程在临床的应用提供指导.方法 对北京大学口腔医学院·口腔医院儿童口腔科门诊279名2～＜8岁首次就诊儿童的家长进行问卷调查,并对儿童就诊时的行为表现进行评价记录,将通过问卷调查获得的影响因素代入以往研究所获得的回归方程[logit(P)=-0.884a+1.212b+ 1.063c+0.918d +0.955,P:概率值;a:年龄;b:监护人预测;c:是否存在行为方面的问题;d:是否有牙痛史]进行验证,对得出的预测值与儿童实际行为表现间的异同进行比较.结果 回归方程预测准确率为84.2％(235/279);回归方程的敏感度为0.613(95％ CI:0.514 ～0.712),特异度为0.957(95％ CI:0.928 ～0.986),阳性预测值为0.877(95％CI:0.797 ～0.957),阴性预测值为0.832(95％ CI:0.782 ～0.882).结论 该回归方程有较好的预测准确性,年龄小、有牙痛史、存在一般的行为问题及家长对儿童行为表现预测为不配合者,在口腔诊疗中多表现为对治疗不配合.To test and verify the regression equation got before for children's dental behavior management problems(BMP).The study group included 279 children aged 2- < 8 years who received dental treatment by 16 pediatric dentists in the Department of Pediatric Dentistry, Peking University School of and Hospital of Stomatology. Interviews were conducted with accompanying guardians and children's dental behavior was rated by a modified Venham's clinical anxiety scale and a cooperative behavior rating scale. The variables were put into the regression equation and the results were compared with their dental behavior scale.The accuracy rate of regression equation reached 84.2% (235/279) , sensitivity was 0.613 (95%CI:0.514-0.712) and specificity was 0.957 (95%CI:0.928-0.986).The regression equation is characterized by its accuracy rate at a good level. Younger age, negative guardian expectations of the child's behavior during treatment, anxiety or shyness around strangers, and presence of toothache were four risk factors for children's dental BMP.PubMed中文核心期刊要目总览(PKU)中国科技核心期刊(ISTIC)中国科学引文数据库(CSCD)012726-7294
