Investigated were relations among executive cognitive function (ECF), food intake, and physical activity in 184, fourth grade children. It was hypothesized that self-reported ECF proficiency would predict greater self-reported fruit/vegetable intake and physical activity, but less "snack food" intake. Structural models demonstrated that ECF was significantly correlated with less concurrent snack food intake and greater concurrent fruit/vegetable intake, but not physical activity. Baseline ECF also significantly predicted greater fruit/vegetable intake and physical activity four months later, but not snack food intake. One implication is to promote ECF as a correlate and predictor of food intake and physical activity in children by providing opportunities for youth to practice newly developing ECF capacities.
研究了 184 名四年级儿童的执行认知功能 (ECF)、食物摄入和身体活动之间的关系。假设自我报告的 ECF 熟练程度将预测更多的自我报告的水果/蔬菜摄入量和身体活动量,但“零食”摄入量更少。结构模型表明,ECF 与同期零食摄入量减少和水果/蔬菜摄入量增加显著相关,但与身体活动量无关。基线 ECF 也显著预测了四个月后水果/蔬菜摄入量和身体活动量的增加,但不能预测零食摄入量的增加。一个含义是,通过为年轻人提供练习新发展的 ECF 能力的机会,将 ECF 作为儿童食物摄入和身体活动的相关因素和预测因素来促进。
