Background: Eating behaviours are associated with childhood obesity, but their associations with cardiometabolic risk are less clear.
Objectives: We evaluated cross-sectional associations between eating behaviours and cardiometabolic risk among 185 adolescents (age 12.4 ± 0.7 years; 53% female; body mass index (BMI)-z 0.72 ± 1.37) from Cincinnati, Ohio (HOME Study; enrolled 2003-2006).
Methods: Caregivers assessed adolescents' eating behaviours with the Child Eating Behaviour Questionnaire. We computed adolescents' cardiometabolic risk scores based on HOMA-IR, triglycerides to high-density lipoprotein cholesterol ratio, adiponectin to leptin ratio, systolic blood pressure, and cross-sectional area of fat inside the abdominal cavity. Using multivariable linear regression models, we estimated associations of eating behaviour subscales with cardiometabolic risk scores or individual risk components.
Results: Emotional overeating (ß = 1.34, 95% CI: 0.67, 2.01), food responsiveness (ß = 0.99, 95% CI: 0.41, 1.57), and emotional undereating (ß = 0.64, 95% CI: 0.08, 1.21) were associated with higher cardiometabolic risk scores. Satiety responsiveness (ß = -0.79, 95% CI: -1.59, 0.00) was associated with lower cardiometabolic risk scores. Adjusting for adolescent BMI-z at age 12 attenuated these associations, suggesting that adiposity may mediate these associations.
Conclusion: Hedonistic eating behaviours were associated with higher cardiometabolic risk in these adolescents.
