Is daytime napping associated with inflammation in adolescents?

Area of Science:

• Adolescent Health
• Sleep Science
• Inflammation Biomarkers

Background:

• Daytime napping is linked to poor health in adults, but its impact on adolescent health is unclear.
• Adolescents frequently nap, necessitating research into potential health consequences.
• Inflammation markers, such as high-sensitivity C-reactive protein and interleukin-6 (IL-6), are indicators of adverse health.

Purpose of the Study:

• To investigate the association between daytime napping and inflammation markers (IL-6) in healthy high school students.
• To determine if napping frequency and duration correlate with elevated IL-6 levels.
• To explore the relationship between actigraphy-measured napping and IL-6 in an adolescent population.

Main Methods:

• 234 Black and White high school students participated.
• Actigraphy and daily diaries were used to measure sleep and napping over one week.
• Fasting blood samples were collected to measure IL-6 and high-sensitivity C-reactive protein.

Main Results:

• Napping frequency, measured by actigraphy, was positively associated with increased IL-6 levels.
• Napping between 2 p.m. and 10 p.m. showed a significant association with higher IL-6.
• Nap duration and diary-reported napping did not show significant associations with IL-6.

Conclusions:

• Actigraphy-assessed napping frequency is associated with elevated IL-6 in adolescents.
• The direction of the napping-IL-6 relationship requires further investigation.
• Napping is a crucial factor in understanding adolescent sleep and cardiovascular health.
