神经影像学研究表明，大脑结构和功能与儿童的饮食行为和体重存在关联，将大脑测量纳入肥胖风险评估和干预的可行性正在增加。然而，人们对大脑如何影响肥胖的看法知之甚少。我们在三项独立的研究中调查了父母对大脑对肥胖的贡献的看法：1）一项针对青少年母亲的神经影像学研究（n = 88），2）一项针对5-13岁奥尔兹的华裔父母参与父母喂养调查的研究（n = 277），3）对3-15岁奥尔兹的父母完成在线调查的研究（n = 113）。一般来说，父母认为大脑因素影响肥胖，但认为它们的影响力不如饮食和运动等行为。大脑因素的因果归因与遗传因素和生物因素的归因相关（例如，代谢）。那些认为自己的孩子超重或高度关注孩子未来超重的父母认为大脑因素在决定孩子的体重方面更重要，更有可能降低孩子控制体重的能力。我们的研究结果表明，父母将肥胖归因于大脑在一定程度上，教育或反馈大脑对肥胖的影响可能是一个有前途的肥胖干预组成部分。
Neuroimaging studies demonstrate associations of brain structure and function with children’s eating behaviour and body weight, and the feasibility of integrating brain measures into obesity risk assessment and intervention is growing. However, little is known about lay perceptions of how the brain influences obesity. We investigated parent perceptions of brain contributions to obesity in three separate studies: 1) a study of mothers of adolescents recruited for neuroimaging research (n = 88), 2) a study of ethnically Chinese parents of 5–13 year olds participating in a parent feeding survey (n = 277), and 3) a study of parents of 3–15 year olds completing an online survey (n = 113). In general, parents believed that brain factors influence obesity, but considered them less influential than behaviours such as diet and exercise. Causal attributions for brain factors were correlated with attributions for genetic factors and biological factors (e.g., metabolism). Parents who perceived their child to be overweight or had a high concern about their child becoming overweight in the future rated brain factors as more important in determining their child’s weight and more likely to lessen their child’s ability to control their weight. Our results suggest that parents attribute obesity to the brain to a moderate degree, and that education or feedback regarding brain influences on obesity could be a promising obesity intervention component.
