Abstract

The aim of this study is to examine the relationship between body mass index (BMI) and intelligence quotient scores (IQ). The sample included 11 patients with pediatric multiple sclerosis between 8 and 17 years, mean age 14.45 years (SD = 2.69). The BMI was calculated as weight in kilograms divided by the square of height in meters. The Wechsler Intelligence Scale for Children V and the Abbreviated Weschler Intelligence Scale were used to measure total IQ. Average sample BMI and IQ were 24.61 (SD = 5.53) (range: 19–39.4) and 86.63 (SD = 14.79) (range: 66–111), respectively. Results of the Pearson correlation indicated that there was a significant negative association between BMI and IQ, (r = −0.608, p = 0.042). R-squared was 0.370. We discuss if lower IQ lead to BMI gains or whether overweight/obesity lead to intellectual functioning changes. Implication for practice and future research are presented.

摘要

本研究的目的是探讨体重指数（BMI）和智商分数（IQ）之间的关系。样本包括 11 名 8 至 17 岁的儿童多发性硬化症患者，平均年龄 14.45 岁 ( SD  = 2.69)。BMI 的计算方法为体重（千克）除以身高（米）的平方。使用韦氏儿童智力量表 V 和缩写韦氏智力量表来测量总智商。平均样本BMI和IQ分别为24.61（SD  =5.53）（范围：19-39.4）和86.63（SD  =14.79）（范围：66-111）。Pearson 相关结果表明，BMI 与 IQ 之间存在显着负相关（r = -0.608，p = 0.042）。R 平方为 0.370。我们讨论智商降低是否会导致体重指数增加，或者超重/肥胖是否会导致智力功能变化。提出了对实践和未来研究的启示。
