Obesity is an established risk factor for cognitive impairment. Theories of cognitive reserve suggest that premorbid factors, such as intellectual ability, may attenuate the expression of cognitive impairment due to age or disease. The current study examined whether cognitive reserve, defined as estimated premorbid intellectual ability, moderates the relationship between obesity and cognitive function in obese adults. Participants without major medical or psychological conditions completed a computerized battery of neuropsychological tests. Hierarchical regression models found a significant interaction between BMI and cognitive reserve for attention/executive function and memory, suggesting that cognitive reserve attenuates the expression of obesity-related cognitive impairment.
肥胖是认知障碍的既定危险因素。认知储备理论表明,智力等前期因素可能会减轻由于年龄或疾病导致的认知障碍的表现。本研究旨在探讨认知储备(定义为预期的前期智力水平)是否会调节肥胖与肥胖成年人认知功能之间的关系。无重大医学或心理疾病的参与者完成了一系列计算机化神经心理学测试。分层回归模型发现 BMI 与认知储备在注意力/执行功能和记忆方面存在显著交互作用,这表明认知储备可减轻与肥胖相关的认知障碍的表现。
