| Outline of Final Research Achievements |
In the present study, over 500 elderly participants recorded their food intake using a digital camera for 48 hours. Based on the food-photographic record, we estimate the nutrition intake and the longest fasting time. We assess the distribution of the longest fasting time by age group and gender and the association with the prevalence of diabetes and dyslipidemia, urinary melatonin excretion, depressive symptoms, and sleep disturbance.

| Academic Significance and Societal Importance of the Research Achievements |
食事の内容や摂取時刻を客観的に測定するには、多大な労力を要するため、疫学研究が乏しい。本研究はデジタルカメラを用いて推定した絶食時間や栄養摂取を評価し、健康指標との関連を検討した点で新規性が高いと考える。本研究の知見は、適切なタイミングに必要な栄養摂取を促し、メタボリック症候群やフレイルの予防につながるものであり、社会的意義も高いと考える。
