Recent research demonstrates a significant relationship between weight status and impaired reaction time in young, adult, and elderly individuals. However, most such studies were performed on small samples, used only body mass index as the body obesity index, used simple reaction time, and oftentimes did not consider some potential confounders such as age, socioeconomic status, or physical activity in their studies. The present study explored the relationship between various reaction time tasks and various obesity indices in a sample of youth.
Two hundred and thirty-four young males (19-24 years) underwent standard anthropometry, various information processing tasks (e.g., clinical reaction time, simple audio and visual reaction time, and choice reaction time), as well as an inhibitory control task (congruent and incongruent Simon reaction time).
Results revealed no significant relationship between any of the information processing tests and body mass index, nor for fat percentage, waist circumference, and waist-to-height ratio after adjustment for potential confounders. A weak positive association was observed only between congruent Simon reaction time (but not incongruent Simon reaction time) and waist circumference in participants (t value = 0.199; Std error = 0.0014; p = 0.047; Cohen's f = 0.09).
Inhibitory control, but not information processing speed, was associated only with waist circumference in apparently healthy young men.

最近的研究表明，体重状况与年轻人、成年人和老年人的反应时受损之间存在显著关系。然而，大多数此类研究的样本量较小，仅使用身体质量指数作为肥胖指数，使用简单的反应时，并且在研究中经常不考虑一些潜在的混杂因素，如年龄、社会经济地位或身体活动。本研究探讨了在年轻人样本中，各种反应时任务与各种肥胖指数之间的关系。
234 名年轻男性（19-24 岁）接受了标准人体测量学、各种信息处理任务（例如，临床反应时、简单的视听反应时和选择反应时）以及抑制控制任务（一致和不一致的西蒙反应时）。
结果显示，在调整潜在混杂因素后，任何信息处理测试与体重指数之间，以及与体脂肪百分比、腰围和腰高比之间均无显著关系。仅在参与者中观察到一致的西蒙反应时（但不一致的西蒙反应时没有）与腰围之间存在微弱的正相关关系（t 值=0.199；标准误差=0.0014；p=0.047；Cohen's f=0.09）。
在表型健康的年轻男性中，仅抑制控制，而不是信息处理速度，与腰围相关。
