Abstract
The circadian timing of food intake (i.e., chrononutrition) has been linked to various markers of health status, such as body weight and insulin sensitivity. However, a valid assessment of day-to-day, within-person patterns in chrononutrition has not yet been developed. This paper details the development and initial validity testing of the Chrononutrition Profile – Diary (CP-D). The CP-D assesses 6 components of chrononutrition that are likely to influence health (breakfast skipping, largest meal, evening eating, evening latency, night eating, and eating window). This measure demonstrated preliminary evidence of convergent validity with the ASA24 (Automated Self-Administered 24-hour dietary assessment tool). The CP-D is designed for use by both healthcare professionals and researchers. It can serve as an independent assessment of day-to-day patterns of chrononutrition, and can also be used along with existing dietary measures to provide a comprehensive assessment of participants' and patients' daily eating behaviors and meal timing patterns.
