这篇文章的目的是评估儿童不健康饮食模式和整体学习成绩之间的关系。摘要本研究以2001 ~ 2002年台湾省小学生营养与健康调查为研究对象，采用多阶段复杂抽样设计。调查对象包括2222名在人口统计学、人体测量学、饮食和生活方式、整体学习成绩等方面拥有完整数据的小学生。采用t检验和chi(2)检验比较综合成绩优异者的特征差异。采用因子分析方法，将22个食物组的食物频次分为5个因子，用于构建饮食模式。在对已知危险因素进行调整后，通过多元逻辑回归评估饮食模式与不利整体表现之间的关系。台湾小学生整体表现不佳的比率为7.1%。总体学习成绩不佳与不健康的饮食模式呈正相关，不健康的饮食模式包括大量摄入低质量食物（如糖果和油炸食品），低摄入乳制品和高营养密度食物（如蔬菜、水果、肉、鱼和鸡蛋）。不健康饮食习惯越多的孩子在学校的整体表现就越差。研究表明，总体而言，儿童的学业成绩不佳。在学校表现优异的学生更有可能吃甜食和油炸食品，而不太可能吃富含蛋白质、维生素和矿物质的食物。在我们的研究中，食物摄入频率和食物偏好之间的正相关关系支持了饮食模式和不良整体学业表现之间的潜在关系。
The objective of this article is to evaluate the relationship between children's unhealthful eating patterns and overall school performance. The Nutrition and Health survey in Taiwan Elementary School Children, 2001-2002, was carried out by using a multistaged complex sampling design. A total of 2,222 elementary school children who had complete data on demographics, anthropometrics, diet and lifestyle, and overall school performance were included in the analyses. Differences in characteristics between children with favorable and unfavorable overall performance were compared using t test and chi(2) test. Using factor analysis, food frequency of 22 food groups was grouped into five factors, which were used to construct dietary patterns. The association between dietary patterns and unfavorable overall performance was assessed by multiple logistic regression after adjustment for known risk factors. Prevalence of unfavorable overall performance in Taiwanese elementary school children was 7.1%. Unfavorable overall school performance was positively associated with unhealthful eating patterns, which included high intake of low-quality foods (eg, sweets and fried foods) and low intake of dairy products and highly nutrient-dense foods (eg, vegetables, fruit, meat, fish, and eggs). Children with a greater number of unhealthful eating patterns were more at risk for unfavorable overall performance in school. The study shows that children with unfavorable overall. school performance were more likely to eat sweets and fried foods, and were less likely to eat foods rich in protein, vitamins, and minerals. A potential relationship between eating patterns and unfavorable overall school performance is supported by a positive relationship between frequency of food intake and food preferences in our study.
