Contribution of dietary sources to vitamin D status is not clearly known. Although sunlight exposure is a major source of circulating serum 25(OH)D, diet is an important contributor in absence of or reduced exposure. Objective of this study was to determine relation between dietary patterns and serum 25(OH)D concentrations of US children using assay‐adjusted serum 25(OH)D data. Data from 2 cycles of the National Health and Nutrition Examination Survey 2003–2004 and 2005–2006 for individuals aged ≤ 19 y, were used to study the association between dietary patterns and serum 25(OH)D. Dietary patterns were established using factor analysis based on food‐frequency questionnaire data. Eigenvalues and Scree plot were used to derive 2 major principle factors. They were labeled as Western and Healthy dietary patterns. Serum 25(OH)D was significantly lower in Healthy dietary pattern group compared to Western dietary pattern group (61.9 vs 66.1 nmol/L; P <.002). In multivariate analysis, children with higher Western dietary contribution scores to overall diet showed a significant positive relation with serum 25(OH)D (β=33.8, P =.046). Serum 25(OH)D is associated with Western dietary pattern but not with Healthy pattern. Children consuming healthy pattern diet may benefit from vitamin D supplementation and sunlight exposure (outdoor activities). Grant Funding Source : None
