Objective: To examine how the dietary patterns of children at various time points throughout childhood relate to estimated nutrient intakes. %26lt;br%26gt;Design: FFQ at 3, 4, 7 and 9 years of age were completed by mothers. Dietary patterns were identified cross-sectionally using principal component analysis; %26apos;processed%26apos;, %26apos;health conscious%26apos; and %26apos;traditional%26apos; patterns were consistently obtained. Correlations between pattern scores and nutrient intakes and proportions of variance in nutrients explained by the patterns were calculated. %26lt;br%26gt;Setting: Avon Longitudinal Study of Parents and Children (ALSPAC), Bristol, UK. %26lt;br%26gt;Subjects: Children provided data between 3 and 9 years of age (n 8010 to 10 023). %26lt;br%26gt;Results: Dietary patterns explained substantial proportions of the variance of the absolute intake for most nutrients (%26gt;25% at 3 years of age, %26gt;40% other ages). After energy adjustment, protein, fibre, K, Mg, Fe, Zn, folate, thiamin and vitamin B-6 continued to be well explained. Strong correlations were observed between the %26apos;processed%26apos; pattern and macronutrients including energy (r = 0.481-0.619), total fat (r = 0.529-0.662) and total sugar (r = 0.475-0.693). However correlations with most micronutrients were reversed after energy adjustment, suggesting that the %26apos;processed%26apos; pattern is energy-dense but nutrient-poor. The %26apos;health conscious%26apos; and %26apos;traditional%26apos; patterns were strongly positively correlated with protein, fibre and most micronutrients, whether energy adjusted or not. Higher scores on these patterns were associated with a better nutrient profile. %26lt;br%26gt;Conclusions: Dietary patterns explain a reasonable amount of the variation in the nutrient content of diets. Higher scores on the %26apos;health conscious%26apos; and %26apos;traditional%26apos; dietary patterns were related to better nutrient profiles; conversely, with higher scores on the %26apos;processed%26apos; pattern the nutrient profile was poorer.
