Abstract：
The academic success of children contributes to their income, social status, and public health. This study was conducted with 217 elementary school students from western China. Scores on the Chinese Children Dietary Index (CCDI), Dietary Approaches to Stop Hypertension (DASH), adjusted DASH, and KIDMED index were calculated to evaluate diet quality. Eating behavior and sleep quality were assessed using the Children\'s Eating Behavior Questionnaire (CEBQ) and Children\'s Sleep Habits Questionnaire (CHSQ), respectively. Academic achievement was measured using school-provided average grades. Higher CCDI scores, longer sleep time, lower total CHSQ scores, and lower subscores on \"satiety responsiveness,\" \"slowness in eating,\" \"emotional undereating,\" and \"food fussiness\" dimensions of the CEBQ were associated with high academic achievement. In conclusion, good diet quality, sleep quality, healthy eating behaviors, and adequate sleep duration were associated with better academic performance. Interventions are recommended to be developed in education system to improve healthy diets and lifestyles, enhancing academic achievement.
