    Serum 25-hydroxyvitamin D levels and the prevalence of peripheral arterial disease: results from NHANES 2001 to 2004. Melamed ML, Muntner P, Michos ED, Uribarri J, Weber C, Sharma J, Raggi P. Arterioscler Thromb Vasc Biol. 2008 Jun;28(6):1179-85. Epub 2008 Apr 16. PMID: 18417640 doi: 10.1161/ATVBAHA.108.165886 Conclusions- Low serum 25(OH)D levels are associated with a higher prevalence of PAD. Several mechanisms have been invoked in the literature to support a potential antiatherosclerotic activity of vitamin D. Prospective cohort and mechanistic studies should be designed to confirm this association. Vitamin D is an inhibitor of the renin-angiotensin system and has antiinflammatory and anticoagulant properties. Among 4839 NHANES 2001 to 2004 participants, low 25(OH)D levels were associated with a higher prevalence of PAD, after multivariate adjustment. To confirm this association, longitudinal cohort and mechanistic studies are needed.

    Serum 25-hydroxyvitamin D status of the US population: 1988-1994 compared with 2000-2004. Looker AC, Pfeiffer CM, Lacher DA, Schleicher RL, Picciano MF, Yetley EA. Am J Clin Nutr. 2008 Dec;88(6):1519-27. PMID: 19064511 doi:10.3945/ajcn.2008.26182 Conclusions: Overall, mean serum 25(OH)D was lower in 2000-2004 than 1988-1994. Assay changes unrelated to changes in vitamin D status accounted for much of the difference in most population groups. In an adult subgroup, combined changes in BMI, milk intake, and sun protection appeared to contribute to a real decline in vitamin D status. In summary, age-standardized mean serum 25(OH)D concentrations based on observed values were significantly lower in 2000-2004 than in 1988-1994 in all groups examined. Adjustment for assay changes noticeably reduced the difference between surveys. However, mean serum 25(OH)D concentrations remained significantly lower in males (except Mexican Americans) in NHANES 2000-2004 than in NHANES III, even after adjustment for assay differences. This remaining difference likely represents a real decline in vitamin D status. Changes in BMI, milk intake, and sun protection appeared to contribute to this decline in a subgroup of non-Hispanic white adults. The possibility that trends in overweight, sun protection, and milk intake may continue supports the need to continue monitoring the serum 25(OH)D status of the population

    Prevalence and Associations of 25-Hydroxyvitamin D Deficiency in US Children: NHANES 2001-2004. Kumar J, Muntner P, Kaskel FJ, Hailpern SM, Melamed ML. Pediatrics. 2009 Aug 3.

    The prevalence of hypovitaminosis D among US adults: data from the NHANES III. Zadshir A, Tareen N, Pan D, Norris K, Martins D. Ethn Dis. 2005 Autumn;15(4 Suppl 5):S5-97-101. PMID: 16315387 CONCLUSION: Serum levels of 25(OH) D3 are below the recommended levels for a large portion of the general adult population and in most minorities. Need exists for a critical review and probable revision of current recommendations for adult vitamin D intake to maintain adequate 25(OH) D3 levels.

    Demographic differences and trends of vitamin D insufficiency in the US population, 1988-2004. Ginde AA, Liu MC, Camargo CA Jr. Arch Intern Med. 2009 Mar 23;169(6):626-32. PMID: 19307527 Conclusions National data demonstrate a marked decrease in serum 25(OH)D levels from the 1988-1994 to the 2001-2004 NHANES data collections. Racial/ethnic differences have persisted and may have important implications for known health disparities. Current recommendations for vitamin D supplementation are inadequate to address the growing epidemic of vitamin D insufficiency.

    "High serum selenium associated with elevated LDL and total cholesterol By Helen Albert 21 January 2010 Atherosclerosis 2009; Advance online publication MedWire News: High levels of serum selenium are associated with elevated total and low-density lipoprotein (LDL) cholesterol, report US researchers. The results add weight to those of a previous UK study, reported by MedWire News, that reported an association between high plasma selenium and an adverse lipid profile. Eliseo Guallar (Johns Hopkins University Bloomberg School of Public Health, Baltimore, Maryland) and colleagues carried out a cross-sectional analysis of 1159 individuals aged 56.8 years on average who participated in the National Health and Nutrition Examination Survey (NHANES) 2003-2004."

    Optimal vitamin D status attenuates the age-associated increase in systolic blood pressure in white Americans: results from the third National Health and Nutrition Examination Survey. Judd SE, Nanes MS, Ziegler TR, Wilson PW, Tangpricha V. Am J Clin Nutr. 2008 Jan;87(1):136-41. PMID: 18175747 Conclusions: SBP is inversely associated with serum vitamin D concentrations in nonhypertensive white persons in the United States. This observation provides a rationale for studies on the potential effects of vitamin D supplementation as a method to reduce SBP in persons at risk of hypertension.
