The researchers profiled the vitamin D levels of 10,899 subjects over a 5 year period; the mean age of the study group was 58 +/-15 years, 71% were women, and the average BMI was 30.
The key results of interest were:
- 29.7% of subjects were in the normal vitamin D range.
- 70.3% of subjects were vitamin D deficient.
- Several cardiovascular related diseases, including hypertension, coronary artery disease, cardiomyopathy, and diabetes were strongly corelated with the vitamin D deficient group.
The researchers concluded that vitamin D deficiency was associated with a significant risk of cardiovascular disease and premature death while vitamin D supplementation was significantly associated with better mortality, specifically in patients with documented deficiency.
The study results and conclusions certainly raise a valid case for everyone to be taking a vitamin D supplement or at the very least, particularly in the 40+ year age group, discussing supplementation with their doctor.
