Abstract：
Obesity is an emerging threat and a current challenge for children and adolescents worldwide. The aim of the present work was to evaluate the relationship between the Dietary Antioxidant Index (DAI) and the weight status of students in early adolescence. A sample of 1580 students aged 10-12 years from 47 primary schools in Greece were enrolled. Anthropometric characteristics were assessed, and calculation of the Body Mass Index (BMI) was used to categorize students into two weight-status groups. Dietary habits and physical activity were evaluated using a self-completed questionnaire, and the DAI was calculated through derived micronutrients\' content, along with energy, macro-, and micro-nutrient intake. Crude and adjusted regression analysis showed a significant inverse association of the DAI and body weight status (Odds Ratio (OR): 0.719, 95% Confidence Interval (CI): 0.576; 0.897, and adjusted Odds Ration (aOR): 0.667, 95% CI: 0.489; 0.907). An antioxidant diet seems to play a protective role against increased body weight among students in early adolescence. Thus, dietary patterns rich in antioxidants should be promoted to facilitate healthy habits early in life, and to fight the obesity threat.
摘要：
肥胖是全球儿童和青少年面临的新兴威胁和当前挑战。本工作的目的是评估饮食抗氧化指数（DAI）与青春期早期学生体重状况之间的关系。来自希腊47所小学的1580名10-12岁学生的样本被录取。评估了人体测量特征，体重指数（BMI）的计算用于将学生分为两个体重状态组。使用自我填写的问卷评估饮食习惯和身体活动，DAI是通过衍生的微量营养素含量计算的，随着能量,宏-，和微量营养素的摄入。粗略和调整后的回归分析显示DAI和体重状态呈显著负相关(比值比(OR):0.719,95%置信区间(CI):0.576;0.897,和调整后的比值比(aOR):0.667,95%CI:0.489;0.907)。抗氧化剂饮食似乎对青春期早期学生的体重增加起保护作用。因此，应提倡富含抗氧化剂的饮食习惯，以促进生命早期的健康习惯，对抗肥胖威胁.
