To examine the relationship between children's overweight status and other cardiovascular risk fitness factors and academic performance among fifth-grade students.
Using a sample of 968 fifth-grade students (50.7% boys; mean age = 10.6 years), children's cardiovascular risks (BMI, blood pressure, acanthosis nigricans) and fitness measures were compared with their mean group performance scores across four subscales (mathematics, reading/language arts, science, and social studies) of a statewide standardized academic performance test.
Of this sample, 39% were either at risk for being overweight or were already overweight; slightly over one half were of normal weight. Initial findings revealed a significant relationship between children's weight category and their reading/language arts, mathematics, and science test scores even after controlling for a proxy of socioeconomic status. When additional cardiovascular risk and fitness measures were included in the model, however, children's BMI status had no association. Instead, a composite fitness index, children's blood pressure, sex, and proxy of socioeconomic status were significantly associated with children's academic test scores.
This study expanded our understanding of the connection between children's overweight risks and academic performance by examining the impact of other cardiovascular risk factors such as high blood pressure and measures of fitness. These findings support the development and implementation of childhood cardiovascular risk surveillance programs that evaluate not only children's overweight risks but also their fitness, risk for type 2 diabetes, and/or high blood pressure by showing a relationship between some of these risks and children's academic test performance.
研究五年级学生的超重状况与其他心血管疾病风险健康因素及学业成绩之间的关系。
以968名五年级学生（男生占50.7%；平均年龄 = 10.6岁）为样本，将儿童的心血管疾病风险（体重指数、血压、黑棘皮症）和健康指标与其在全州标准化学业成绩测试四个子量表（数学、阅读/语言艺术、科学和社会研究）上的平均成绩进行比较。
在这个样本中，39%的学生有超重风险或已经超重；略超过一半的学生体重正常。初步研究结果显示，即使在控制了社会经济地位的一个替代指标之后，儿童的体重类别与他们的阅读/语言艺术、数学和科学测试成绩之间仍存在显著关系。然而，当模型中纳入更多心血管疾病风险和健康指标时，儿童的体重指数状况并无关联。相反，一个综合健康指数、儿童的血压、性别以及社会经济地位的替代指标与儿童的学业测试成绩显著相关。
本研究通过考察高血压等其他心血管疾病风险因素和健康指标的影响，扩展了我们对儿童超重风险与学业成绩之间联系的理解。这些发现支持了儿童心血管疾病风险监测项目的开发与实施，这些项目不仅评估儿童的超重风险，还通过显示其中一些风险与儿童学业测试成绩之间的关系，评估他们的健康状况、2型糖尿病风险和/或高血压风险。
