Outline of Final Research Achievements

This study identified meal patterns and examined their association with frailty among community-dwelling older Japanese. The prevalence of prefrailty and frailty was higher among participants who reported eating balanced meals on ≦2 or 3 days/week than among those who ate such meals daily. In addition, substitution of protein intake at breakfast or lunch for protein intake at dinner was associated with lower prevalence of prefrailty and frailty. These findings indicate that more-frequent twice daily consumption of meals with a staple food, main dish, and side dish, increased protein intake at breakfast and lunch, and a protein intake evenly distributed throughout all daily meals may decrease the risks of frailty.
