Abstract：
BACKGROUND: Early childhood caries (ECC) is a challenge for pediatric dentists all over the world, and dietary factor is an important factor affecting the occurrence of ECC. Currently, there is limited research on the impact of dietary nutrient intake from Chinese diets on ECC. The purpose of this study is to explore the correlation of dietary nutrients intake with ECC and caries activity (CA) among children aged 3-5 years, and to provide dietary guidance to slow down the occurrence and development of ECC.
METHODS: A cross-sectional study was conducted in 2022. A total of 155 children were divided into three groups: caries-free group, ECC group and Severe early childhood caries (SECC) group according to the caries statues. And according to the caries activity test (CAT) value, they were also divided into three group: low CA group (L-CA), middle CA group (M-CA) and high CA group (H-CA). The 24-hour dietary intake information was collected by mobile phone application (APP). The intake of children\'s daily dietary nutrients were calculated referring to \"China Food Composition Tables\".
RESULTS: In this study, 17, 39,and 99 children were diagnosed with caries-free, ECC, and SECC. There were 33, 36, and 86 children diagnosed with L-CA, M-CA, and H-CA. The risk of ECC was increased with the intake of cholesterol(OR = 1.005) and magnesium (OR = 1.026) and decreased with the intake of iron (OR = 0.770). The risk of SECC was increased with the intake of cholesterol (OR = 1.003). The risk of high CA was increased with the intake of cholesterol (OR = 1.002). The combined application of dietary total calories, carbohydrate, cholesterol, sodium, magnesium and selenium in the diagnosis of ECC had an area under ROC curve of 0.741.
CONCLUSIONS: The increased dietary cholesterol intake may be a common risk factor for ECC and high CA in children aged 3-5. The combined application of dietary intake of total calories, carbohydrate, cholesterol, sodium, magnesium and selenium has a higher predictive value for the occurrence of ECC.

摘要：
背景：幼儿龋齿（ECC）是全世界儿科牙医面临的挑战，而膳食因素是影响ECC发生的重要因素。目前,关于中国饮食中的膳食营养摄入对ECC的影响的研究有限。这项研究的目的是探讨3-5岁儿童的膳食营养素摄入量与ECC和龋齿活动（CA）的相关性。并提供饮食指导，减缓ECC的发生和发展。
方法：2022年进行了一项横断面研究。共有155名儿童被分为三组：无龋组，ECC组和严重早期儿童龋齿（SECC）组根据龋齿雕像。并根据龋齿活性试验(CAT)值,他们也被分为三组：低CA组（L-CA），中CA组(M-CA)和高CA组(H-CA)。通过手机应用程序（APP）收集24小时饮食摄入量信息。儿童每日膳食营养素的摄入量是参照“中国食品成分表”计算的。
结果：在这项研究中，17、39和99名儿童被诊断为无龋齿，ECC,SECC。有33、36和86名儿童被诊断患有L-CA，M-CA,和H-CA.ECC的风险随胆固醇（OR=1.005）和镁（OR=1.026）的摄入而增加，而随铁的摄入而降低（OR=0.770）。随着胆固醇的摄入，SECC的风险增加（OR=1.003）。随着胆固醇的摄入，高CA的风险增加（OR=1.002）。膳食总热量的联合应用，碳水化合物，胆固醇,钠,镁和硒在ECC诊断中的ROC曲线下面积为0.741。
结论：膳食胆固醇摄入增加可能是3-5岁儿童ECC和高CA的常见危险因素。联合应用膳食摄入的总热量，碳水化合物，胆固醇,钠,镁和硒对ECC的发生具有较高的预测价值。
