Model 1: adjusted for sex and age. Model 2: additionally adjusted for residency, highest level of parental education, region, physical activity and energy intake. Model 3: additionally included use of classifications of geographical regions as cluster groups to analyze the association. Dietary patterns were identified at baseline (in 2006). p-value for trend was obtained by adjusting the quartiles of the pattern scores as a continuous variable. p-values< 0.05 are bold
