Association Between Multi-Dimensional Sleep Health and Breakfast Skipping in Japanese High School Students.

Area of Science:

• Adolescent Health
• Sleep Science
• Nutritional Behavior

Background:

• Breakfast skipping is linked to adverse health outcomes like metabolic disorders and cognitive impairments.
• Existing research shows partial links between sleep and breakfast, but lacks comprehensive, multi-dimensional sleep health analysis.
• Few studies have systematically examined sleep health's impact on breakfast behavior under controlled conditions.

Purpose of the Study:

• To investigate the association between multi-dimensional sleep health and breakfast skipping among Japanese high school students.
• To determine if sleep quality, daytime sleepiness, and wake-up times are independently related to breakfast skipping.
• To provide novel insights into the relationship between sleep health indicators and breakfast behavior.

Main Methods:

• A study involving 2969 Japanese high school students.
• Sleep data collected via sleep diaries (1-8 days) including meal timing.
• Sleep quality assessed using the Pittsburgh Sleep Quality Index (PSQI) and daytime sleepiness using the Pediatric Daytime Sleepiness Scale (PDSS).

Main Results:

• Later wake-up times were associated with a higher likelihood of breakfast skipping.
• Lower sleep quality (PSQI) correlated with increased breakfast skipping.
• Greater daytime sleepiness (PDSS) was linked to a higher probability of skipping breakfast.
• No significant interactions were found between wake-up time, PSQI, and PDSS regarding breakfast skipping.

Conclusions:

• Multi-dimensional sleep health, encompassing wake-up time, sleep quality, and daytime sleepiness, is significantly associated with breakfast skipping.
• These sleep health indicators appear to be independent factors influencing breakfast behavior in adolescents.
• The study highlights the importance of considering sleep health when addressing breakfast skipping and related health outcomes.
