Abstract

OBJECTIVES Few studies have examined whether cognitive function predicts dietary intake. The majority of research has focused on how diet can influence cognitive performance or risk for cognitive impairment in later life. The aim of this study was to examine prospective relationships between cognitive performance and dietary intake in participants of the Maine-Syracuse Longitudinal Study. DESIGN A prospective study with neuropsychological testing at baseline and nutritional assessments measured a mean of 18 years later. SETTING Community-dwelling individuals residing in central New York state. PARTICIPANTS 333 participants free of dementia and stroke. MEASUREMENTS The Wechsler Adult Intelligence Scale (WAIS) was assessed at baseline and dietary intake was measured using the Nutrition and Health Questionnaire. RESULTS Higher WAIS Scores at baseline were prospectively associated with higher intakes of vegetables, meats, nuts and legumes, and fish, but inversely associated with consumption of total grains and carbonated soft drinks. After adjustment for sample selection, socioeconomic indicators, lifestyle factors (smoking and physical activity), and cardiovascular risk factors, the relations between higher cognitive performance and greater consumption of vegetables, meat, and fish, and lower consumption of grains remained significant. CONCLUSION These data suggest that cognition early in life may influence dietary choices later in life.

较高的认知能力与健康的饮食选择有关:缅因州雪城纵向研究。
目的很少有研究考察认知功能是否能预测饮食摄入量。大多数研究都集中在饮食如何影响认知表现或晚年认知障碍的风险上。本研究的目的是研究缅因州-锡拉丘兹纵向研究参与者的认知表现和饮食摄入之间的潜在关系。设计一项前瞻性研究,在基线进行神经心理测试,并在平均18年后进行营养评估。居住在纽约州中部的社区居民。参与者:333名无痴呆和中风的参与者。测量方法以韦氏成人智力量表(WAIS)为基准进行评估,并使用营养与健康问卷测量饮食摄入量。结果较高的基线WAIS分数与较高的蔬菜、肉类、坚果、豆类和鱼类摄入量相关,但与全谷物和碳酸软饮料的摄入量呈负相关。在对样本选择、社会经济指标、生活方式因素(吸烟和体育活动)和心血管风险因素进行调整后,较高的认知表现与更多的蔬菜、肉类和鱼类消费以及较少的谷物消费之间的关系仍然显著。结论:这些数据表明,生命早期的认知可能会影响生命后期的饮食选择。
