目的了解无锡市初中生的口腔健康行为,为口腔预防保健工作的开展和相关口腔卫生政策的制定提供依据。方法采取分层等比整群抽样的方法抽取无锡市13所中学初二年级的1 651名学生,对其进行口腔健康行为的问卷调查。结果 87%的学生在3个月内会更换牙刷,92.6%的学生每天刷牙≥2次,刷牙时间≥3 min的占15.2%,35.4%的学生采用竖刷法,使用含氟牙膏的比例为58.0%,5.8%的学生使用过牙线。频率、刷牙时间、刷牙方式、更换牙刷时间和使用含氟牙膏方面,不同地区、性别间比较差异均有统计学意义(P值均<0.05);使用牙线方面城区好于郊区;吃糖果频率和饮用碳酸饮料方面城郊和男女比较差异均有统计学意义(P值均<0.05)。结论无锡地区城郊和不同性别学生的口腔基本保健知识水平差异较大。口腔健康教育工作需要进一步加强,并在相关口腔卫生政策的制定上适度偏向郊区。
Objective To understand the oral health behaviors of junior high school students in Wuxi City, and to provide basis for the development of oral preventive health care and related oral hygiene policies. Methods A total of 1 651 students in 13 primary and secondary schools in 13 middle schools in Wuxi City were selected by stratified equal-combined cluster sampling to conduct oral questionnaires on their oral health behaviors. Results 87% of students changed their toothbrush within 3 months, 92.6% of students brushed ≥2 times daily, brushing time was ≥3 min and accounted for 15.2%, 35.4% of students used vertical brushing, and the proportion of using fluoride toothpaste was 58.0%, 5.8% of students used dental floss. Frequency, brushing time, brushing time, toothbrush replacement time, and use of fluoride toothpaste had statistically significant differences in different regions and genders (P<0.05); urban areas with dental floss were better than those in suburbs; There were statistically significant differences between the suburbs and men and women in drinking carbonated drinks (P < 0.05). Conclusion There is a great difference in oral basic health care knowledge among suburban and gender-educated students in Wuxi. Oral health education needs to be further strengthened, and it is moderately biased toward the suburbs in the formulation of related oral hygiene policies.
