    Objective: This study aimed to assess associations between chronotype and obesity-related indicators in a sample of Spanish adolescents.Methods: This cross-sectional study used data from The Eating Healthy and DailyLife Activities (EHDLA) Study, which included a representative sample of adolescentsfrom Spain. A total of 820 adolescents (54.7% girls) aged 12–17 years were includedin the analyses. The adolescents' chronotype was determined using the Morning-ness/Eveningness Scale in Children. Obesity-related indicators included body massindex, waist circumference, waist-to-height ratio, triceps and medial calf skinfolds,sum of skinfolds, and body fat percentage. Generalized linear models were used toexamine the relationship between the Morningness-Eveningness score and chrono-type status and the above-mentioned obesity-related indicators in adolescents. Allanalyses were adjusted for sex, age, socioeconomic status, sleep duration, physicalactivity, sedentary behaviour, adherence to the Mediterranean diet, and energyintake.Results: The morningness chronotype was associated with higher abdominal obesity(odds ratio [OR] = 1.67, 95% confidence interval (CI) 1.12 to 2.50; p = 0.001), waist-to-height ratio (unstandardized beta coefficient [B] = 0.01, 95% CI 0.01 to 0.05;p = 0.029) and skinfold calves (B = 1.04 95% CI 0.24 to 1.94; p = 0.011), comparedwith the intermediate chronotype.Conclusion: Adolescents with a morningness chronotype may be more prone toabdominal obesity than their counterparts with an intermediate chronotype. Effec-tive intervention-related approaches can be applied to those with a morningnesschronotype
