Abstract

We analyzed the association between dietary intake and chronotype as assessed by both MorningnessEveningness Questionnaire (MEQ) score and preferred midpoint of sleep in 112 young Japanese women. Dietary intake was assessed by a brief, self-administered diet history questionnaire. A lower MEQ score (evening-type tendency) showed a significant association with a lower energy-adjusted intake of protein, calcium, magnesium, zinc, vitamins (D, riboflavin, and B6), and vegetables, and with a higher intake of noodles. Furthermore, a later midpoint of sleep showed a significant association with a lower energy-adjusted intake of protein, cholesterol, potassium, calcium, magnesium, zinc, vitamins (D, riboflavin, B6, and B12), soy, fish and shellfish, and eggs, and with a higher intake of noodles, bread, and confections. These data suggest that evening chronotype is associated with inadequate dietary habits such as low vitamin and mineral intakes.
