Lack of Association between Obesity and Dental Caries in Three-Year-Old Children

齲齒與糖類的關係衆所熟知，研究顯示發生齲齒的主因是吃糖的頻率，而不是吃糖的數量；肥胖的主因是攝食過多的熱量，糖類雖是熱量的來源之一，但研究顯示油脂可能才是最重要的因數。綜合上述，糖類與齲齒、肥胖雖然似有相關，但肥胖與齲齒並無必然之關聯，不過，最近瑞典之研究指出青少年之齲齒及老年人之假牙及咀嚼能力似乎與肥胖略有關係。本研究擬探討亂胖是否較易有齲齒？齲齒的數目是否較多？民國83年10月至84年5月，臺北市政府對三歲兒童進行全面性的健康篩檢，本研究以5133名健檢資料完整的三歲幼兒爲樣本，依身高、體重及身體質量指數作爲體位之分類，而齲齒之有無與顆數則以牙醫師檢查之齲齒與填補齒結果爲依據。個案中包括2822名男童及2311名女童，由於各項結果並無性別差異，故合併統計分析身體質量指數將幼兒分爲五組：肥胖(佔6.5%)、過重(18.1%)、標凖(48.6%)、過輕(20.6%)及身體質量指數小於五百分位以下(6.1%)之五組中，發生齲齒之比例分別爲50.9%、55.6%、55.4%、57.9%及56.8%，無明顯差異；而五組中有齲齒幼兒之平均齲齒數目分別爲4.1、4.1、4.2、4.3及4.7顆，各變項間亦無統計學上之差異。此種結果顯示：臺北市三歲幼童之肥胖與否與齲齒並無明顯關係；不過，齲齒及肥胖之高盛行率，值得小兒科及營養學界注意。

To investigate whether the obese children are prone to develop dental caries, the cross-sectional data from a Three-year-old Children's Health Survey were evaluated. The body weight, height, body mass index(BMI), and decayed and filled teeth(dft) score were analyzed in 5,133 children. The prevalence of dental caries was not different significantly among different BMI groups. There were no significant differences in the dft score of carious children among different BMI groups. Little or no relationship was found between BMI and dft score. We conclude that there is no relationship between carious deciduous teeth and weight status in three-year-old children.
