IRRs and 95% CIs for diagnoses of internalizing disorder and ADHD by the EQ-5D-Y dimensions among grade five students participating in the 2012 REAL Kids survey, Alberta, Canada.

Variables	Internalizing disorder: IRR (95% CI)			ADHD: IRR (95% CI)

Adjusted model 1, adjusted for the variables in the table and the following demographic variables: gender, residency, parental education, and household income; adjusted model 2, additionally adjusted for health behaviors (diet quality, physical activity, use of computers/video games, and TV viewing) from the adjusted model 1. The adjusted models also adjusted for energy intake. All estimates were weighted to represent population estimates.

IRRs, incidence rate ratios; CIs, confidence intervals; ADHD, attention deficit and hyperactivity disorder; ref., reference group; DQI, diet quality index. Bold values indicate statistical significance (p < 0.05).
