本研究為「台灣地區國小學童營養健康狀況調查2001-2002」的子計畫,抽取代表國小學童的樣本,主要目的為:調查國小學童的齲齒數與齲齒盛行率、並評估其與學童的甜食與乳製品攝取之間的關係。所探討的乳製品包括:牛奶、優酪乳、及起司,甜食包括:餅乾、糖果巧克力、冰棒、及含糖飲料。使用SAS及SUDAAN進行運算,分析齲齒狀況以及與上兩類食品的關係。共有2405名學童完成口腔檢查與問卷調查,調查回應率為96.35%。所有學童之齲齒盛行率為87.0%,12歲男、女學童的恆牙齲齒盛行率分別為64.9% vs 82.5%、DMFT index分別為2.2顆與3.6顆。在調整干擾因子之後,與恆牙齲齒指數顯著相關者為牛奶、起司及冰棒,與乳牙齲齒指數顯著相關者為起司及餅乾的攝取,乳牙齲齒數隨著餅乾攝取天數的增加呈現直線上升的趨勢。本研究結果顯示:台灣地區國小學童的齲齒盛行率偏高,亟需改進。甜食中,冰棒的攝取與學童恆牙齲齒的增加、糖果巧克力與餅乾的攝取則與乳牙齲齒的增加顯著相關。乳品中,牛奶對恆牙齲齒,起司對乳牙齲齒有保護作用。
The purpose of this study was to investigate the current oral health condition of schoolchildren in Taiwan, and its relationship with the consumption of sweet snacks and dairy products. This study is a subproject of the ”Elementary Schoolchildren's Nutrition and Health Survey in Taiwan 2001-2002.” A representative sample of schoolchildren in Taiwan was selected by a stratified multistage cluster sampling design. Information on the dietary habits and oral health condition was collected from each participant. The dairy products discussed in this study included the number of servings per day of milk, yogurt, and cheese; the weekly frequencies of sweet snacks included cookies, candy/chocolate, popsicles, and sugared drinks. Statistical analyses were conducted by SAS and SUDAAN. There were 2405 subjects who completed both the oral examination and questionnaire. The overall caries prevalence was 87.0%. The caries prevalence rates of permanent teeth were 64.9% for boys and 82.5% for girls; the DMFT indices were 2.2 and 3.6, respectively. After adjusting for potential confounding factors, the DMFT index was statistically significantly associated with milk, cheese, and popsicles. The increase in deft was significantly associated with increasing frequencies of weekly cookie consumption.
