Background Whether concentrations of vitamin D are related to mortality remains unresolved. Our objective was to examine the relationship between serum concentrations of 25-hydroxyvitamin D and all-cause mortality in a national sample of US adults.

Methods We used data from the National Health and Nutrition Examination Survey Mortality Study from 2001 to 2004 with mortality compiled through 2006. Mortality status was established through a match to the National Death Index.

Results Of the 7531 participants, 347 died. Median follow-up was 3.8 years. The mean unadjusted concentrations of vitamin D were 54.1?nmol/l (21.7?ng/ml) among participants who died and 60.7?nmol/l (24.3?ng/ml) among participants who survived (P? =?0.002). After adjustment for socio-demographic factors, the hazard ratios (HR) for all-cause mortality were 1.65 95% confidence interval (CI): 95% CI: 1.13–2.40 for participants with a concentration <50?nmol/l (<20?ng/ml) and 1.02 (95% CI: 0.74–1.41) for participants with a concentration of 50 to <75?nmol/l (20 to <30?ng/ml) compared with participants who had a concentration of ?75?nmol/l (?30?ng/ml). After more extensive adjustment, the HRs were 1.28 (95% CI: 0.86–1.90) and 0.91 (95% CI: 0.63–1.33), respectively. The fully adjusted HR per 10?nmol/l of vitamin D was 0.93 (95% CI: 0.86–1.01). The HRs did not vary by gender (P?=?0.80) or among the three major racial or ethnic groups (P?=?0.46).

Conclusions Concentrations of vitamin D were weakly and inversely related to all-cause mortality in this sample of US adults.

66% more likely to die if vitamin D <20ng than if >30 ng

see wiki page http://www.vitamindwiki.com/tiki-index.php?page_id=1359

It was politically incorrect to have 66% as a conclusion. Afterall, the Institute of Medicine was soon to announce that 20ng was OK

So they took out the associations of death due to diabetes, smoking,

etc, etc, and got it down to 'only' 28% more likely to die
