Adolescents' chronotype and its association with obesity‐related outcomes: The Eating Healthy and Daily Life Activities (EHDLA) study
Authors' conclusion
Adolescents with a morningness chronotype may be more prone to abdominal obesity than their counterparts with an intermediate chronotype. Effective intervention-related approaches can be applied to those with a morningness chronotype.
Study context
- Population
- Spanish adolescents aged 12–17 years (54.7% girls), EHDLA Study
- Participants
- 820 adolescents
- Exposure
- Morningness vs intermediate chronotype
- Outcome
- Obesity-related indicators: BMI, waist circumference, waist-to-height ratio, triceps and medial calf skinfolds, sum of skinfolds, body fat percentage
Methodological detailsrepresentative sample, adjusted for sex, age, socioeconomic status, sleep duration, physical activity, sedentary behaviour, Mediterranean diet adherence and energy intake
- Representative sample
- Adjusted for sex, age, socioeconomic status, sleep duration, physical activity, sedentary behaviour, Mediterranean diet adherence and energy intake
Main finding
As reported in the abstract
Obesity-related indicators
Morningness vs IntermediateOdds ratio (abdominal obesity) (95% CI)P value
Higher abdominal obesity with morningness
1.67(1.12–2.50)
P = 0.001- Obesity-related indicators
- unstandardized beta coefficient (waist-to-height ratio) 0.01 (95% CI 0.01–0.05); P = 0.029
- Obesity-related indicators
- unstandardized beta coefficient (calf skinfold) 1.04 (95% CI 0.24–1.94); P = 0.011
Observational data: associations, not effects.
