This study aims to estimate the free sugars intake, identify the primary food sources of free sugars, and explore the relationship between free sugars intake and dental caries among Chinese adolescents. This cross-sectional study included 1517 middle-school students aged 12-14 years in Changsha city, China. Adolescents completed a 12-item Food Frequency Questionnaire (FFQ) and oral health assessment. The students' dental caries experience was available as DMFT score (number of decayed, missing, and filled permanent teeth). Statistical analyses included the Mann-Whitney test, Kruskal-Wallis test, Chi-square test, and binary logistic regression model. The average intake of free sugars was 53.1 g/d in adolescents, and 43.2% of the students consumed more than 50 g of free sugars daily. The primary contributor to free sugars was sugar-sweetened beverages (SSBs). Age, boarders, and high family income were risk factors for excessive free sugars intake ( < 0.05), and increased free sugars intake was a risk factor for dental caries (odds ratio, OR = 1.446, 95% confidence interval: 1.138-1.839). Both the free sugars intake and dental caries prevalence in Chinese adolescents were high. Targeted interventions are urgently needed to address the excessive consumption of free sugars and improve Chinese adolescents' oral health.
本研究旨在估计中国青少年的游离糖摄入量，确定游离糖的主要食物来源，并探讨游离糖摄入量与龋齿之间的关系。这是一项横断面研究，纳入了中国长沙市 12-14 岁的 1517 名中学生。青少年完成了 12 项食物频率问卷（FFQ）和口腔健康评估。学生的龋齿经历可用 DMFT 评分（龋失补的恒牙数）表示。统计分析包括 Mann-Whitney 检验、Kruskal-Wallis 检验、卡方检验和二元逻辑回归模型。青少年的游离糖平均摄入量为 53.1 g/d，43.2%的学生每天摄入超过 50 g 的游离糖。游离糖的主要来源是含糖饮料（SSBs）。年龄、寄宿生和高家庭收入是游离糖摄入过量的危险因素（<0.05），而游离糖摄入增加是龋齿的危险因素（比值比，OR=1.446，95%置信区间：1.138-1.839）。中国青少年的游离糖摄入量和龋齿患病率均较高。迫切需要采取有针对性的干预措施来解决游离糖的过度消费问题，改善中国青少年的口腔健康。
