Inhibitory control (IC) is an executive function that plays a central role in the capability to control one's attention and behavior. Growing evidence suggests that deficits in IC are related to calorie consumption and obesity development. However, there are only a few studies that have addressed this issue prospectively. The aim of the present study was to evaluate the influence of IC on anthropometric changes at one year follow up in a cohort of Argentinian adolescents.
A prospective cohort study of 569 students (264 boys and 305 girls) aged 13.18 ± 0.36 years at initial evaluation and 14.22 ± 0.29 years at follow up was performed. IC was assessed at baseline and at follow up by means of a computerized Go/No-Go task, and anthropometric measures were performed following standardized procedures. At follow up an abbreviated Three Factor Eating Questionnaire (TFEQ-R21C) was performed.
Cross sectional analysis performed at the age of 14 revealed an association between IC and obesity, meanwhile at the age of 13 IC was associated with the degree of obesity. Prospective analysis showed that a lower IC at baseline predicted a higher increase in body mass index (BMI) and waist circumference at one year of follow up. Subjects with lower IC at follow up rated higher in the uncontrolled eating domain of TFEQ-R21C and presented higher snacking frequency.
A higher IC capacity at baseline might be associated with a more favorable evolution in BMI and waist circumference. A low IC at follow up is associated with obesity and higher uncontrolled eating. This suggests that the identification of subjects with low IC might be useful in order to detect adolescents at risk of obesity at earlier stages.
抑制控制（IC）是一种执行功能，在控制注意力和行为的能力中起着核心作用。越来越多的证据表明，IC缺陷与热量摄入和肥胖发展有关。然而，只有少数研究前瞻性地探讨了这个问题。本研究的目的是评估IC对一组阿根廷青少年随访一年时人体测量变化的影响。
进行了一项前瞻性队列研究，初始评估时有569名学生（264名男孩和305名女孩），年龄为13.18±0.36岁，随访时为14.22±0.29岁。在基线和随访时通过计算机化的停止信号任务评估IC，并按照标准化程序进行人体测量。随访时进行了简化的三因素饮食问卷（TFEQ-R21C）。
14岁时进行的横断面分析显示IC与肥胖之间存在关联，而13岁时IC与肥胖程度相关。前瞻性分析表明，基线时IC较低预测随访一年时体重指数（BMI）和腰围增加较高。随访时IC较低的受试者在TFEQ-R21C的非控制饮食领域得分较高，且零食频率较高。
基线时较高的IC能力可能与BMI和腰围更有利的变化相关。随访时IC较低与肥胖和较高的非控制饮食有关。这表明识别IC较低的受试者可能有助于在早期阶段检测有肥胖风险的青少年。
