1 080名15岁青少年患龋情况及社会-行为危险因素的影响

Study of dental caries and the influence of social-behavioral risk factors on dental caries of 1 080 15-year-old adolescents

目的了解湖北省15岁青少年患龋情况和口腔健康行为,评价社会-行为危险因素对青少年患龋情况的影响。方法按照多阶段、分层、等容量、不等比、随机抽样的原则,对湖北省15岁青少年进行调查,临床检查评价青少年患龋的情况,采用问卷调查表收集人群的口腔健康知识、态度和行为。结果湖北省1 080名15岁青少年的龋均和患龋率分别为0.45和24.4%。每天刷牙至少2次和拜访牙医的青少年比例分别是11.4%和33.1%。Logistic回归分析显示,女生患龋的概率是男生的1.70倍;与从未拜访牙医、消耗含糖饮料频率较低的学生相比,拜访牙医、消耗含糖饮料频率较高的青少年患龋几率较高。结论湖北省青少年患龋水平较低,口腔卫生行为较差,性别和消耗含糖饮料是影响湖北省青少年龋病的社会-行为危险因素。

Objective To describe the dental caries of 15-year-old adolescents in Hubei province,and to determine the influence of various social-behavioral risk factors on dental caries in the population.Methods The survey employed a multistage,stratified,non-geometric proportional randomized sampling,representing adolescents aged 15-year-old in Hubei province.The epidemiological investigation of dental caries was made by clinical oral health examination.Oral health knowledge,attitude and behavior investigated by questionnaire.Results The prevalence and mean DMFT in 1 080 15-year-old adolescents in Hubei province was 24.4% and 0.45,respectively.11.4% of the adolescents brushed their teeth at least twice a day,33.1% of the adolescents ever visited the dentists.A significant higher prevalence of dental caries was observed in girls（OR=1.70）.In addition,those who visit dentists and those who the scores of the consumption of sugar drink were high tended to have a higher prevalence of dental caries.Conclusion The dental caries prevalence of adolescents in Hubei province is low,but oral health habit of adolescents seems poor.Gender and consumption of sugar drink may be risk factors of dental caries.
