The objective of this study was to investigate the association between food patterns and serum vitamin D concentrations in US adults. Data from two cycles of National Health and Nutrition Examination Surveys, 2003-2004 and 2005-2006, were used ( 6637). Three major food patterns were derived using factor analysis. These three patterns were labeled as meat and processed meat foods (MPF), vegetables, fruit, nuts, and whole grains (VFNW), and sweet, snack, and beverage pattern (SSB). Serum vitamin D was measured with RIA and later standardized to reflect the assay changes over time. In multivariate-adjusted regression analysis, the MPF pattern was significantly, inversely associated with serum vitamin D concentrations ( < 0·001). However, the relation between the VFNW pattern and serum vitamin D was non-linear ( < 0·001). There was no relationship between SSB pattern and serum vitamin D in US adults. In conclusion, persons with a high intake of meat and processed meats are associated with lower serum vitamin D concentrations. Reducing processed foods and emphasizing VFNW will be beneficial from a health perspective.
本研究的目的是调查美国成年人饮食模式与血清维生素D浓度之间的关联。使用了2003 - 2004年和2005 - 2006年两个周期的国家健康和营养检查调查数据（6637人）。通过因子分析得出三种主要饮食模式。这三种模式分别被标记为肉类和加工肉类食品模式（MPF）、蔬菜、水果、坚果和全谷物模式（VFNW）以及甜食、零食和饮料模式（SSB）。血清维生素D用放射免疫分析法测量，随后进行标准化以反映随时间的检测变化。在多变量调整回归分析中，MPF模式与血清维生素D浓度显著负相关（<0.001）。然而，VFNW模式与血清维生素D之间的关系是非线性的（<0.001）。在美国成年人中，SSB模式与血清维生素D之间没有关系。总之，肉类和加工肉类摄入量高的人血清维生素D浓度较低。从健康角度来看，减少加工食品并强调VFNW模式将是有益的。
