Photodermatology, Photoimmunology & Photomedicine; Volume 28, Issue 3, pages 159–161, June 2012

From conclusion: Smoking was associated with an increased risk of hypovitaminosis D (odds ratio, 1.8; 95% confidence interval, 1.00–3.35).


Many Studies mentioning Smoking and Vitamin D


The influence of smoking on vitamin D status and calcium metabolism

European Journal of Clinical Nutrition December 1999, Volume 53, Number 12, Pages 920-926

Results: Fifty percent were current smokers. Smokers had significantly reduced levels of serum 25OHD (P=0.02), 1,25(OH)2D (P=0.001), and PTH (P<0.001). There was no difference in serum ionized calcium between smokers and non-smokers. We found a negative effect of smoking on serum osteocalcin (P=0.01), while urinary pyridinolines were similar in the two groups. The small differences in lifestyle between the two groups could not explain these findings. Smokers had small but significant reductions in bone mineral density.


Vitamin D deficiency, Smoking, and Lung Function in the Normative Aging Study; 2012

Measurements and Main Results: In the overall cohort, there was no significant effect of vitamin D deficiency on lung function nor on lung function decline.
In both cross-sectional and longitudinal multivariable models there was effect modification by vitamin D status on the association between smoking and lung function.
Cross-sectional analysis revealed lower lung function in current smokers with vitamin D deficiency (FEV1, FVC, and FEV1/FVC, p? 0.0002) and longitudinal analysis showed more rapid rates of decline in FEV1 (p=0.023) per pack-year of smoking in subjects with vitamin D deficiency as compared to subjects who were vitamin D sufficient.

Conclusions: Vitamin D deficiency was associated with lower lung function and more rapid lung function decline in smokers over 20 years in this longitudinal cohort of elderly men. This suggests that vitamin D sufficiency may have a protective effect against the damaging effects of smoking on lung function. Future studies should seek to confirm this finding in the context of smoking and other exposures that affect lung function.
