潮州市15～17岁学生口腔健康知识及行为调查

目的：探讨潮州市15～17岁学生对口腔健康知识的了解情况及其口腔健康行为,为口腔卫生保健工作提供信息支持。方法采用分层整群随机抽样的方法,按照样本纳入标准抽取潮州市15～17岁学生933名进行问卷调查。所使用问卷参照第四次全国口腔健康流行病学调查问卷,结合本课题研究目的设计。问卷内容包括：人口统计学和社会学资料、口腔健康知识和口腔健康行为。对问卷调查资料进行分析。结果仅13.1%的学生认同“窝沟封闭可保护牙齿”。女生（t=5.198）、父亲受教育程度较高者（t=2.667）口腔健康知识得分较高（P<0.01）。刷牙频率与年龄和性别相关,年龄较大者（c2=23.002）和女生（c2=98.722）每天刷牙2次或以上的比例较高（P<0.001）。75.2%的学生不知道自己使用的牙膏是否含氟,91.5%的学生没有使用过牙线。口腔科就诊经历在性别（c2=16.406）和母亲受教育程度（c2=12.566）方面的差异具有统计学意义（P<0.01）。结论潮州市15～17岁学生口腔健康知识及行为需要积极改善,男生、低年龄组和父母受教育程度低者是重点教育对象。

A survey on oral health knowledge and behaviors of 15 to 17 years old students in Chaozhou

Objective To investigate the oral health knowledge and behaviors of 15 to 17 years old students in Chao?zhou and provide necessary information for oral health care plans. Methods A questionnaire investigation was conduct?ed among 933 students aged 15?17 years from Chaozhou. They were recruited using stratified cluster random sampling method. The questionnaire was designed on the basis of the questionnaire for the fourth national oral health survey as well as the objectives of the present study. The questionnaire involved a range of questions, including demographic and social information, oral health knowledge and behaviors. Analyses were made for the data of the questionnaire. Results Only 13.1%of students knew that pit and fissure sealant can protect teeth. The girls (t=5.198) and those whose father had high?er education level (t=2.667) had higher oral health knowledge score (P<0.01). The frequency of tooth brushing was signif?icantly associated with age (c2=23.002) and gender (c2=98.722) (P<0.001). The girls and those who were older had high?er proportions of brushing their teeth twice or more daily. 75.2%of students did not know whether the toothpaste they used contained fluoride or not, and 91.5%of students never used dental floss. The use of dental service was significant associat?ed with gender (c2=16.406) and their maternal education level (c2=12.566) (P<0.01). Conclusion The oral health knowledge and behaviors of 15 to 17 years old students from Chaozhou are needed to be improved actively. Oral health edu?cation should be focused on those who are boys and younger, and whose parents have lower education level.
