大学生における栄養素摂取状況および情緒的傾向と衝動性傾向との関連性

抄録

  The purpose of the present investigation is to determine how one′s nutritional status affects an unsettled state of mind, especially the impulsivity trait, in university students. Three hundred twenty-four university students completed a self-rating questionnaire. They were assessed using a brief-type self-administered diet history questionnaire (BDHQ), the Barratt Impulsiveness Scale (11th version; BIS-11), and the Beck Depression Inventory-Second Edition (BDI-II). Based on BDHQ scores, the participants were classified into three groups according to their nutrient intake: low-energy density nutrient intake, moderate-energy density nutrient intake, and high-energy density nutrient intake. A one-way analysis of variance revealed significantly higher BIS-11 scores in the case of low-energy protein intake and low dietary intake of the soy and soy food groups. The vitamin and mineral deficiencies influenced the impulsivity trait, and the n-6 fatty acid deficiency possibly led to an increase in the impulsivity level. The results suggest that an unbalanced nutritional status is a risk factor for a higher impulsiveness in university students.
