包头市3~5岁儿童龋病患病的相关因素分析

目的:分析包头市3~5岁儿童龋病患病的相关因素。方法:于包头市随机抽取的10所幼儿园中,随机选择3~5岁儿童496名为研究对象。经口腔医生检查,发现患龋病326例,为病例组,未患龋病170名,为对照组。对两组年龄、性别、每日进零食次数和每日刷牙次数等25项可能与患龋病有关的因素予以调查、记录。以logistic多元回归筛选相关因素。结果:排除进入模型的其他因素混杂作用后,每日进零食次数每增加1次,促进患龋病的危险是原来的1.249倍(OR=1.249>1,其95%可信区间内不包含1,P<0.05);断奶时间≥1岁促进患龋病的危险是＜1岁断奶的2.812倍(OR=2.812>1,其95%可信区间内不包含1,P<0.01);而不含奶瓶入睡、睡前不吃零食和不喝碳酸饮料促进患龋病的危险分别是含奶瓶入睡、睡前吃零食和喝碳酸饮料的0.194、0.302和0.031倍(OR分别是0.194、0.302和0.031,均OR<1,其95%可信区间内均不包含1,均P<0.01)。结论:增加进零食次数和断奶时间≥1岁是包头市3~5岁儿童患龋病的危险因素;而不含奶瓶入睡、睡前不吃零食和不喝碳酸饮料为其保护因素。

Analysis of Related Factors to the Dental Caries of 3-5-Year-Old Children in Baotou.

Objective: To analyze the related factors of the dental caries of 3-5-year-old children in Baotou. Methods: Four hundred and ninety-six 3-5-year-old children were randomly selected from 10 kindergartens in Baotou. 326 children who had caries were set as the case group and 170 children without caries as the control group by oral professional medical examination. 25 factors related to dental caries were investigated and recorded in two groups such as age, gender, daily snack times and daily brushing times, and so on. Then the related factors were analyzed with logistic multiple regression. Results: After excluding other factors involved in the model, per increase of daily snack time promoted the occurrence of dental caries 1.249 fold (OR was 1.249 and the 95% confidence interval did not contain 1, P<0.05). Weaning more than 1-year-old promoted the occurrence of dental caries 2.812 fold (OR was 2.812 and the 95% confidence interval did not contain 1, P<0.01). Risks to promote caries of not containing the bottle to sleep, not eating bedtime snack, and not drinking carbonated drinks were 0.194, 0.302, and 0.031 times of doing the above things (OR respectively was 0.194, 0.302, and 0.031, and all their 95% confidence interval did not contain 1, P<0.01). Conclusion: Increasing snack times and more than 1-year-old weaning are the dental caries risk factors of 3-5-year-old children of Baotou, while not containing the bottle to sleep, not eating bedtime snack, and not drinking carbonated drinks are the protective factors.
