CONCLUSIONS: According to available evidence from longitudinal studies, serum 25(OH)D is not associated with PC incidence.

Interpretation
Maternal vitamin D insufficiency is common during pregnancy and is associated with reduced bone-mineral accrual in the offspring during childhood; this association is mediated partly through the concentration of umbilical venous calcium. Vitamin D supplementation of pregnant women, especially during winter months, could lead to longlasting reductions in the risk of osteoporotic fracture in their offspring.
Both high and low levels of blood vitamin D are associated with a higher prostate cancer risk: a longitudinal, nested case-control study in the Nordic countries.

Conclusions: The endocrine circuitry regulating serum calcium may be altered in MS. There is an inverse relationship between serum vitamin D level and MS clinical activity. The role of vitamin D in MS must be explored further.

Conclusions Our results support suggestions that serum 25(OH)D is inversely related to CRC risk.

Conclusions- Low serum 25(OH)D levels are associated with a higher prevalence of PAD. Several mechanisms have been invoked in the literature to support a potential antiatherosclerotic activity of vitamin D. Prospective cohort and mechanistic studies should be designed to confirm this association.
Vitamin D is an inhibitor of the renin-angiotensin system and has antiinflammatory and anticoagulant properties. Among 4839 NHANES 2001 to 2004 participants, low 25(OH)D levels were associated with a higher prevalence of PAD, after multivariate adjustment. To confirm this association, longitudinal cohort and mechanistic studies are needed.

In conclusion, calcium and vitamin D consumption were associated with brain lesions in elderly subjects even after controlling for potentially explanatory variables. These associations may be due to vascular calcification or other mechanism. The possibility of adverse effects of high intakes of calcium and vitamin D needs to be further explored in longitudinal studies of elderly subjects.
