Relationships between 25-Hydroxyvitamin D Levels and Plasma Glucose and Lipid Levels in Pediatric Outpatients. Johnson MD, Nader NS, Weaver AL, Singh R, Kumar S. J Pediatr. 2009 Nov 17. [Epub ahead of print] PMID: 19926097 Conclusions Low 25(OH) D levels in children and adolescents are associated with higher plasma glucose and lower HDL concentrations.

Lack of association between serum levels of 25-hydroxyvitamin D and the subsequent risk of prostate cancer in Finnish men. Faupel-Badger JM, Diaw L, Albanes D, Virtamo J, Woodson K, Tangrea JA. Cancer Epidemiol Biomarkers Prev. 2007 Dec;16(12):2784-6. PMID: 18086789 doi: 10.1158/1055-9965.EPI-07-0672

Association between depressive symptoms and 25-hydroxyvitamin D in middle-aged and elderly Chinese. Pan A, Lu L, Franco OH, Yu Z, Li H, Lin X. J Affect Disord. 2009 Nov;118(1-3):240-3. Epub 2009 Feb 27. PMID: 19249103 doi:10.1016/j.jad.2009.02.002 Conclusions Depressive symptoms are not associated with 25(OH)D concentrations in middle-aged and elderly Chinese. Further prospective studies are required to determine whether they are correlated.

Relationship between low ultraviolet B irradiance and higher breast cancer risk in 107 countries. Mohr SB, Garland CF, Gorham ED, Grant WB, Garland FC. Breast J. 2008 May-Jun;14(3):255-60. Epub 2008 Apr 17. PMID: 18422861 DOI: 10.1111/j.1524-4741.2008.00571.x There was a protective effect of UVB irradiance on risk of breast cancer that was independent of fertility rate, proportion of the population overweight, alcohol intake, animal energy intake, and other covariates.

Inverse association between serum 25(OH) vitamin D levels and non-melanoma skin cancer in elderly men. Tang JY, Parimi N, Wu A, John Boscardin W, Shikany JM, Chren MM, Cummings SR, Epstein EH Jr, Bauer DC; for the Osteoporotic Fractures in Men (MrOS) Study Group. Cancer Causes Control. 2009 Nov 18. [Epub ahead of print] PMID: 19921445 Our results suggest that a diagnosis of NMSC is not a surrogate for adequate 25(OH)D levels or increased UV exposure, and high 25(OH)D levels may be associated with a reduced risk of NMSC.

Association between 25-hydroxyvitamin D levels and cognitive performance in middle-aged and older European men. Lee DM, Tajar A, Ulubaev A, Pendleton N, O'Neill TW, O'Connor DB, Bartfai G, Boonen S, Bouillon R, Casanueva FF, Finn JD, Forti G, Giwercman A, Han TS, Huhtaniemi IT, Kula K, Lean ME, Punab M, Silman AJ, Vanderschueren D, Wu FC; EMAS study group. J Neurol Neurosurg Psychiatry. 2009 Jul;80(7):722-9. Epub 2009 May 21. PMID: 19460797 doi:10.1136/jnnp.2008.165720 Conclusion: In this study, lower 25(OH)D levels were associated with poorer performance on the DSST. Further research is warranted to determine whether vitamin D sufficiency might have a role in preserving cognitive function in older adults.

Estimation of the dietary requirement for vitamin D in free-living adults >=64 y of age. Cashman KD, Wallace JM, Horigan G, Hill TR, Barnes MS, Lucey AJ, Bonham MP, Taylor N, Duffy EM, Seamans K, Muldowney S, Fitzgerald AP, Flynn A, Strain JJ, Kiely M. Am J Clin Nutr. 2009 May;89(5):1366-74. Epub 2009 Mar 18. PMID: 19297462 doi:10.3945/ajcn.2008.27334 Conclusion: To ensure that the vitamin D requirement is met by the vast majority (>97.5%) of adults aged ≥64 y during winter, between 7.9 and 42.8 µg vitamin D/d is required, depending on summer sun exposure and the threshold of adequacy of 25(OH)D. .

Fracture prevention with vitamin D supplementation: a meta-analysis of randomized controlled trials. Bischoff-Ferrari HA, Willett WC, Wong JB, Giovannucci E, Dietrich T, Dawson-Hughes B. JAMA. 2005 May 11;293(18):2257-64. Review. PMID: 15886381 Conclusions Oral vitamin D supplementation between 700 to 800 IU/d appears to reduce the risk of hip and any nonvertebral fractures in ambulatory or institutionalized elderly persons. An oral vitamin D dose of 400 IU/d is not sufficient for fracture prevention.

Baseline serum 25-hydroxy vitamin d is predictive of future glycemic status and insulin resistance: the Medical Research Council Ely Prospective Study 1990-2000. Forouhi NG, Luan J, Cooper A, Boucher BJ, Wareham NJ. Diabetes. 2008 Oct;57(10):2619-25. Epub 2008 Jun 30. PMID: 18591391 doi: 10.2337/db08-0593 CONCLUSIONS: This prospective study reports inverse associations between baseline serum 25(OH)D and future glycemia and insulin resistance. These associations are potentially important in understanding the etiology of abnormal glucose metabolism and warrant investigation in larger, specifically designed prospective studies and randomized controlled trials of supplementation.

Vitamin D and skin physiology: a D-lightful story. Holick MF, Chen TC, Lu Z, Sauter E. J Bone Miner Res. 2007 Dec;22 Suppl 2:V28-33. PMID: 18290718 doi: 10.1359/jbmr.07s211 Very few foods naturally contain vitamin D, and those that do have a very variable vitamin D content. Recently it was observed that wild caught salmon had between 75% and 90% more vitamin D(3) compared with farmed salmon. The associations regarding increased risk of common deadly cancers, autoimmune diseases, infectious diseases, and cardiovascular disease with living at higher latitudes and being prone to vitamin D deficiency should alert all health care professionals about the importance of vitamin D for overall health and well being. Humans have depended on sunlight for their vitamin D requirement. The impact of season, time of day, and latitude on vitamin D synthesis is well documented.(2,3) We now report that altitude also has a dramatic influence on vitamin D3 production and that living at altitudes above 3500 m permits previtamin D3 production at a time when very little is produced at latitudes below 3400 m. It was surprising that, at 27° N in Agra (169 M), little previtamin D3 production was observed. However, there was significant air pollution that caused a haze over the city. It is likely the ozone and other UVB-absorbing pollutants in the air prevented the solar UVB photons from reaching the earth's surface to produce previtamin D3.

A seasonal variation of calcitropic hormones, bone turnover and bone mineral density in early and mid-puberty girls - a cross-sectional study. Viljakainen HT, Palssa A, Kärkkäinen M, Jakobsen J, Cashman KD, Mølgaard C, Lamberg-Allardt C. Br J Nutr. 2006 Jul;96(1):124-30. PMID: 16870000 Seasonal variation in S-25-OHD and bone remodelling markers accompanied by negative correlation between S-25-OHD and S-iPTH was seen in this cross-sectional study of adolescent girls. In addition, the seasonal rhythm contributed 7.0-7.6 % difference in the BMD of lumbar vertebrae and left femur in early puberty girls. This variation should be avoided since it could hamper peak bone mass attainment.

Association study on two vitamin D receptor gene polymorphisms and vitamin D metabolites in multiple sclerosis. Smolders J, Damoiseaux J, Menheere P, Tervaert JW, Hupperts R. Ann N Y Acad Sci. 2009 Sep;1173:515-20. PMID: 19758194 DOI: 10.1111/j.1749-6632.2009.04656.x Discussion: We found no association of the Apal and Taql VDR gene SNPs with MS or with vitamin D metabolism in our population. Further research should assess the complex interaction between vitamin D, the VDR, and susceptibility to MS.
