Children with ADHD and their community controls were significantly older than sibling (p < 0.001).Likewise, lower tertiles of the second and third nutrient patterns were significantly associated with increasing odds of ADHD, when compared to siblings, and adjusted for study covariates, with significant dose-response gradient (p for trend <0.001 and <0.001, respectively).Lower tertiles of the first two nutrient patterns were significantly associated with increasing odds of ADHD, when compared to community controls, and adjusted for study covariates, with significant dose-response gradient (p for trend = 0.002 and 0.005, respectively).However, higher tertiles of the fourth nutrient pattern was significantly associated with increasing odds of ADHD, when compared to either community controls or siblings, and adjusted for study covariates, with significant dose-response gradient (p for trend <0.001 and <0.001, respectively).However, pairwise comparisons showed insignificant differences in energy-adjusted intakes of fats, copper, phosphorus, and vitamins A and C, when compared between community controls and siblings (p = 0.086, 0.081, 0.208, 0.084, and 0.813, respectively).First, nutrient pattern comprised mainly the energy-adjusted intakes of calcium and phosphorus, and riboflavin, while the second pattern involved a mixture of many minerals and vitamins.In Table 5, binary logistic regression analysis was performed to test for the associations between the tertiles of each nutrient pattern's score (independent variable) and the ADHD (dependent variable).The PCA of the daily energy-adjusted nutrient intakes resulted in extraction of four factors (i.e., nutrient patterns) explaining 75.9% of the total variance.Table 3 shows the four extracted patterns named as: (1) Predominantly Calcium-Phosphorus minerals, (2) predominantly Vitamins, (3) Predominantly Zinc-Iron minerals, and (4) Macronutrient.Only factor loadings >0.30 were reported.
