OBJECTIVE:
Since vitamin D is an important regulator of muscle function, the effect of vitamin D deficiency on frailty syndrome has been recently studied. This cross-sectional study aimed to determine the association between 25(OH)-vitamin D levels and frailty status in Mexican community-dwelling elderly.

METHODS:
Sample of 331 community-dwelling elderly aged 70 or older, a subset of those included in the "Coyoacán cohort" were included. 25(OH)-vitamin D assay and frailty status were measured.

RESULTS:
Mean age was 79.3 years and 54.1% were women. Those classified as frail were more likely to have

• lower Mini-Mental State Examination score (p = 0.015),
• more disability for instrumental activities of daily living (p < 0.001)
• and for activities of daily living (p < 0.001).

Serum 25(OH)-vitamin D levels were lower in the frail subgroup when compared with the non-frail one (p < 0.001). Multivariate logistic regression analyses showed a significant association between intermediate tertile [odds ratios (OR) = 4.13; 95% confidence intervals (CI) 2.00-8.56] or insufficient tertile (OR = 8.95; 95% CI 2.41-33.30) of vitamin D levels and frailty even after adjusting for potential confounders.

CONCLUSION:
These results suggest that older adults with low 25(OH)-vitamin D levels are associated with the probability to being frail compared with those with sufficient vitamin D levels.

From 10 reasons why seniors have low levels of vitamin D

1. Senior skin produces 3X less Vitamin D for the same sun intensity
2. Seniors have fewer vitamin D receptors as they age
   • (The effect of low Vitamin D receptor genes does not show up on vitamin D test results)
3. Seniors are indoors more than than when they were younger
   • not as agile, weaker muscles; frail, no longer enjoy hot temperatures
   • (if outside, stay in the shade), however, seniors might start outdoor activities like gardening, biking, etc.
4. Seniors wear more clothing outdoors than when younger **+fear skin cancer/wrinkles, sometimes avoid bright light after cataract surgery
5. Seniors often take various drugs which reduce vitamin D (some would not show up on vitamin D test) statins, chemotherapy, anti-depressants, blood pressure, beta-blockers, etc
6. Seniors often have one or more diseases which consume vitamin D ( osteoporosis, diabetes, MS, ...)
7. Seniors generally put on weight at they age - and a heavier body requires more vitamin D
8. Seniors often (40%) have fatty livers – which do not process vitamin D as well
9. Seniors not have as much Magnesium needed to use vitamin D
   (would not show up on vitamin D test)
10. Seniors with poorly functioning kidneys do not process vitamin D as well
    (would not show up on vitamin D test) 2009 full text online  Also PDF 2009
11. Vitamin D is not as bioavailable in senior digestive systems (Stomach acid or intestines?)
