江西省12岁儿童龋病流行现状及其与含糖食物摄入行为的相关分析

目的调查江西省12岁儿童龋病流行现状与含糖食物摄入行为的关联性,为江西省儿童防龋工作提供流行病学依据。方法采用分层多阶段整群抽样法,随机抽取江西省10个县(区)共儿童2 040例的12岁儿童。对儿童进行牙齿健康临床检查,诊断龋齿的发生情况,并采用问卷调查儿童含糖食物摄入情况。采用χ2检验、秩和检验、logistic回归对资料进行统计分析。结果 2 040例12岁儿童患龋率为24.40%。农村患龋率高于城市(27.8%vs. 20.9%,P<0.05),女童高于男童(28.70%vs. 20.10%,P<0.001)。城市儿童龋均低于农村(0.39 vs. 0.55,P<0.001)。Logistic回归分析结果显示:赣州市儿童患龋风险低于九江[OR=0.629,95%CI(0.448,0.883),P=0.007];农村儿童较城市儿童患龋风险更高[OR=1.471,95%CI(1.196,1.810),P<0.001];女童患龋风险高于男童[OR=1.588,95%CI(1.291,1.954),P<0.001];食用甜点心频率越高越容易患龋。结论江西省12岁儿童患龋结果呈现出农村高于城市、女童高于男童、甜点心和甜饮料饮食频率高者易患病等特点。以农村、女童为重点,减少甜点心、甜饮料进食频率,同时,强化以九江市为重点地区的管理,这对预防和减少儿童龋病具有重要意义。

Prevalence of dental caries in twelve-year-old children and its correlation with the behavior of sugary food intake in Jiangxi province

Objectives To investigate the prevalence of dental caries among twelve-year-old children and its correlation with the behavior of sugary food intake in Jiangxi province, so as to provide epidemiological evidence for the prevention of dental caries in Jiangxi province. Methods A stratified, multistage and cluster sampling method was used to randomly select 2040 cases of twelve-year-old children in 10 counties in Jiangxi province. Clinical examination of dental health was performed on children to diagnose dental caries, and questionnaires were used to investigate the intake of sugary food. Chi-square test, rank sum test, and logistic regression were used for statistical analysis. Results The caries prevalence among the 2040 cases of twelve-year-old children in Jiangxi province was 24.40%. The prevalence of caries in the rural areas was higher than that of urban areas(27.8% vs. 20.9%, P<0.05). The prevalence of caries in females was higher than that in males(28.70% vs. 20.10%, P<0.001). The DMFT of urban children was lower than that of rural children(0.39 vs. 0.55, P<0.001). According to logistic regression analysis, the risk of caries among children in Ganzhou was lower than that in Jiujiang(OR=0.629, 95%CI 0.448 to 0.883, P=0.007);the caries risk of rural children was higher than that of urban(OR=1.471, 95%CI 1.196 to 1.810, P<0.001);compared with males, females were more susceptible to dental caries(OR=1.588, 95%CI 1.291 to 1.954, P<0.001), and the caries risk increased with the frequency of eating dessert.Conclusions The prevalence of dental caries among twelve-year-old children in Jiangxi province is such that children in rural areas are higher than that of urban areas, females are higher than males, individuals who consume more sweet desserts and sweet drinks are more likely to develop dental caries. Focusing on rural areas and women, reducing the frequency of sweet desserts and sweet drinks, and strengthening the management of Jiujiang as a key area is of considerable significance in preventing childhood dental caries.
