This study examined the relationship between sweet consumption and academic performance among medical university students in Palestine. A cross-sectional survey was conducted among full-time students selected via stratified sampling. Data on academic performance (self-reported GPA), sweet consumption frequency, and potential confounders (demographics, BMI, parental education, income, breakfast consumption, physical activity, and mental health via the Strengths and Difficulties Questionnaire) were collected using structured questionnaires. Multiple linear regression models were used to assess associations.
Of 355 invited students, 220 completed the survey (response rate: 62%). Nearly half (48.2%) reported consuming sweets daily or more. Frequent sweet consumption was significantly associated with lower GPA in both crude and fully adjusted models (β = - 0.15; 95% CI: - 0.29, - 0.01; p = 0.039). Low physical activity (β = - 0.22; p = 0.008) and abnormal mental health scores (β = - 0.31; p = 0.004) were also independently linked to poorer academic performance. Frequent sweet intake is independently associated with reduced academic achievement among university students, even after adjusting for lifestyle and mental health factors. Promoting healthy eating and mental well-being may support academic success in this population.

本研究调查了巴勒斯坦医科大学学生甜食消费与学业成绩之间的关系。通过分层抽样对全日制学生进行了横断面调查。使用结构化问卷收集了学业成绩（自我报告的平均绩点）、甜食消费频率以及潜在混杂因素（人口统计学、体重指数、父母教育程度、收入、早餐消费、体育活动以及通过优势和困难问卷评估的心理健康状况）的数据。采用多元线性回归模型评估相关性。
在355名受邀学生中，220名完成了调查（回复率：62%）。近一半（48.2%）的学生报告每天或更频繁地食用甜食。在粗模型和完全调整模型中，频繁食用甜食均与较低的平均绩点显著相关（β = -0.15；95%置信区间：-0.29，-0.01；p = 0.039）。低体育活动水平（β = -0.22；p = 0.008）和异常心理健康得分（β = -0.31；p = 0.004）也与较差的学业成绩独立相关。即使在调整了生活方式和心理健康因素后，频繁摄入甜食仍与大学生学业成绩下降独立相关。促进健康饮食和心理健康可能有助于该人群在学业上取得成功。
