    Prospective Study of Serum 25-Hydroxyvitamin D Level, Cardiovascular Disease Mortality, and All-Cause Mortality in Older U.S. Adults. Ginde AA, Scragg R, Schwartz RS, Camargo CA Jr. J Am Geriatr Soc. 2009 Jun 22. [Epub ahead of print] PMID: 19549021 DOI: 10.1111/j.1532-5415.2009.02359.x CONCLUSION: In noninstitutionalized older adults, a group at high risk for all-cause mortality, serum 25(OH)D levels had an independent, inverse association with CVD and all-cause mortality. Randomized controlled trials of vitamin D supplementation in older adults are warranted to determine whether this association is causal and reversible.

    Urgent action needed to improve vitamin D status among older people in England! Hirani V, Tull K, Ali A, Mindell J. Age Ageing. 2009 Nov 23. [Epub ahead of print] PMID: 19934073 CONCLUSIONS: poor vitamin D status of older people continues to be a public health problem in England. Hypovitaminosis D is associated with many risk factors and poor health outcomes. There is now an urgent need for a uniform policy on assessment and dietary supplementation of vitamin D in older people to prevent poor vitamin D status and its negative consequences

Seniors With Insufficient Levels Of Vitamin D At Increased Risk Of Dying From Heart Dis... - 0 views

  •  
    A new study by researchers at the University of Colorado Denver and Massachusetts General Hospital (MGH) shows vitamin D plays a vital role in reducing the risk of death associated with older age. The research, just published in the Journal of the American Geriatrics Society, evaluated the association between vitamin D levels in the blood and the death rates of those 65 and older. The study found that older adults with insufficient levels of vitamin D die from heart disease at greater rates that those with adequate levels of the vitamin.

Vitamin D Status Predicts Physical Performance and Its Decline in Older Persons -- Wich... - 0 views

  •  
    Vitamin D status predicts physical performance and its decline in older persons. Wicherts IS, van Schoor NM, Boeke AJ, Visser M, Deeg DJ, Smit J, Knol DL, Lips P. J Clin Endocrinol Metab. 2007 Jun;92(6):2058-65. Epub 2007 Mar 6. PMID: 17341569 doi:10.1210/jc.2006-1525 ONCLUSIONS: Serum 25-OHD concentrations below 20 ng/ml are associated with poorer physical performance and a greater decline in physical performance in older men and women. Because almost 50% of the population had serum 25-OHD below 20 ng/ml, public health strategies should be aimed at this group.

    Summary of evidence-based review on vitamin D efficacy and safety in relation to bone health. Cranney A, Weiler HA, O'Donnell S, Puil L. Am J Clin Nutr. 2008 Aug;88(2):513S-519S. Review. PMID: 18689393 We found inconsistent evidence of an association between serum 25-hydroxyvitamin D [25(OH)D] concentration and bone mineral content in infants and fair evidence of an association with bone mineral content or density in older children and older adults. The evidence of an association between serum 25(OH)D concentration and some clinical outcomes (fractures, performance measures) in postmenopausal women and older men was inconsistent, and the evidence of an association with falls was fair. We found good evidence of a positive effect of consuming vitamin D-fortified foods on 25(OH)D concentrations. The evidence for a benefit of vitamin D on falls and fractures varied. We found fair evidence that adults tolerated vitamin D at doses above current dietary reference intake levels, but we had no data on the association between long-term harms and higher doses of vitamin D.

Fish consumption and risk of subclinical brain abnormalities on MRI in older adults - 0 views

  •  
    Fish consumption and risk of subclinical brain abnormalities on MRI in older adults. Virtanen JK, Siscovick DS, Longstreth WT Jr, Kuller LH, Mozaffarian D. Neurology. 2008 Aug 5;71(6):439-46. PMID: 18678827 doi: 10.1212/01.wnl.0000324414.12665.b0 Conclusions: Among older adults, modest consumption of tuna/other fish, but not fried fish, was associated with lower prevalence of subclinical infarcts and white matter abnormalities on MRI examinations. Our results add to prior evidence that suggest that dietary intake of fish with higher eicosapentaenoic acid and docosahexaenoic acid content, and not fried fish intake, may have clinically important health benefits

    A preliminary study of the safety, feasibility and cognitive efficacy of soy isoflavone supplements in older men and women. Gleason CE, Carlsson CM, Barnet JH, Meade SA, Setchell KD, Atwood CS, Johnson SC, Ries ML, Asthana S. Age Ageing. 2009 Jan;38(1):86-93. Epub 2008 Dec 2. PMID: 19054783 doi:10.1093/ageing/afn227 Conclusions: these data suggest that administration of 100 mg/day of isoflavones was well tolerated. Plasma genistein and daidzein levels, but not equol, increased with isoflavone administration. Finally, data support the potential cognitive effects of soy isoflavones in older adults.

  •  
    Effects of vitamin D supplementation on strength, physical performance, and falls in older persons: a systematic review. Latham NK, Anderson CS, Reid IR. J Am Geriatr Soc. 2003 Sep;51(9):1219-26. Review. PMID: 12919233 DOI: 10.1046/j.1532-5415.2003.51405. Conclusion: Although there is insufficient evidence that vitamin D supplementation alone improves physical performance in older people, some data suggest a benefit from vitamin D combined with calcium supplementation, but this requires confirmation in large, well-designed trials.

  •  
    Consumption of 2 and 4 egg yolks/d for 5 wk increases macular pigment concentrations in older adults with low macular pigment taking cholesterol-lowering statins. Vishwanathan R, Goodrow-Kotyla EF, Wooten BR, Wilson TA, Nicolosi RJ. Am J Clin Nutr. 2009 Nov;90(5):1272-9. Epub 2009 Sep 16. PMID: 19759170 Conclusions: Consumption of 4 egg yolks/d, and possibly of 2 egg yolks/d, for 5 wk benefited macular health in older adults with low MPOD. Serum HDL cholesterol increased without an increase in LDL cholesterol in this study population, most of whom were taking cholesterol-lowering statins.

Age-Related Changes in the 25-Hydroxyvitamin D Versus Parathyroid Hormone Relationship ... - 0 views

  •  
    Age-related changes in the 25-hydroxyvitamin D versus parathyroid hormone relationship suggest a different reason why older adults require more vitamin D. Vieth R, Ladak Y, Walfish PG. J Clin Endocrinol Metab. 2003 Jan;88(1):185-91. PMID: 12519850 This study shows that all age groups exhibit a high prevalence of 25(OH)D insufficiency and secondary hyperparathyroidism. Older adults are just as efficient in maintaining 25(OH)D, but they need more vitamin D to produce the higher 25(OH)D concentrations required to overcome the hyperparathyroidism associated with their diminishing renal function

25(OH)D Serum Levels Decline With Age Earlier in Women Than in Men and Less Efficiently... - 0 views

  •  
    25(OH)D Serum levels decline with age earlier in women than in men and less efficiently prevent compensatory hyperparathyroidism in older adults. Maggio D, Cherubini A, Lauretani F, Russo RC, Bartali B, Pierandrei M, Ruggiero C, Macchiarulo MC, Giorgino R, Minisola S, Ferrucci L. J Gerontol A Biol Sci Med Sci. 2005 Nov;60(11):1414-9. PMID: 16339327 Conclusions. These findings suggest that the age-associated fall of serum 25(OH)D starts earlier in women than in men and that higher levels of 25(OH)D are required in older compared to younger persons to avoid the age-associated compensatory hyperparathyroidism.

    Fall prevention with supplemental and active forms of vitamin D: a meta-analysis of randomised controlled trials. Bischoff-Ferrari HA, Dawson-Hughes B, Staehelin HB, Orav JE, Stuck AE, Theiler R, Wong JB, Egli A, Kiel DP, Henschkowski J. BMJ. 2009 Oct 1;339:b3692. doi: 10.1136/bmj.b3692. PMID: 19797342 doi: 10.1136/bmj.b3692 Conclusions Supplemental vitamin D in a dose of 700-1000 IU a day reduced the risk of falling among older individuals by 19% and to a similar degree as active forms of vitamin D. Doses of supplemental vitamin D of less than 700 IU or serum 25-hydroxyvitamin D concentrations of less than 60 nmol/l may not reduce the risk of falling among older individuals.
