: Existing studies concerning the associations of cognitive function with adiposity in young adults are sparse. The purpose of the study was to examine the associations of adiposity with cognitive control in young adults. Participants were 213 young adults (98 women and 115 men). Cognitive control was measured using a modified task-switching paradigm. Anthropometrics were measured by standardized procedures. Body fat mass and visceral fat area were measured by bioelectrical impedance analysis. : The results showed that increased body mass index (BMI, = 0.02), body fat percentage ( = 0.02), and visceral fat area ( = 0.01) were significantly correlated with larger global switch costs of accuracy in women. In men, high levels of body fat percentage ( = 0.01) and visceral fat area ( = 0.03) were significantly correlated with larger local switch costs of reaction time. : The results indicated that elevated adiposity was associated with worse performance on measures of cognitive control in young adults.
: 目前关于年轻人肥胖与认知功能之间关系的研究还很有限。本研究旨在探讨年轻人肥胖与认知控制之间的关系。研究对象为 213 名年轻人（女性 98 人，男性 115 人）。使用改良的任务转换范式来测量认知控制。通过标准化程序测量人体测量学指标。通过生物电阻抗分析测量体脂肪量和内脏脂肪面积。结果表明，女性的体重指数（BMI）增加（ = 0.02）、体脂肪百分比（ = 0.02）和内脏脂肪面积（ = 0.01）与准确性的全局转换成本增加显著相关。在男性中，高水平的体脂肪百分比（ = 0.01）和内脏脂肪面积（ = 0.03）与反应时的局部转换成本增加显著相关。结果表明，肥胖程度升高与年轻人认知控制测量中表现较差有关。
