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.
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.
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.
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
- Senior skin produces 3X less Vitamin D for the same sun intensity
- Seniors have fewer vitamin D receptors as they age
- 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.
- Seniors wear more clothing outdoors than when younger
- Seniors also are told to fear skin cancer/wrinkles
- Seniors often take various drugs which reduce vitamin D
- Some reductions would not show up on vitamin D test
- statins, chemotherapy, anti-depressants, blood pressure, beta-blockers, etc
- Seniors often have one or more diseases which consume vitamin D
- osteoporosis, diabetes, MS, ...
- Seniors generally put on weight at they age - and a heavier body requires more vitamin D
- Seniors often (40%) have fatty livers – which do not process vitamin D as well
- Reduced stomach acid ==>less Magnesium needed to utilize vitamin D
(would not show up on vitamin D test)
- 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
- Vitamin D is not as bioavailable in senior digestive systems (Stomach acid or intestines?)
