Vitamin D in the form of vitamin D(3 ) seems to decrease mortality in predominantly elderly women who are mainly in institutions and dependent care .
Vitamin D(2 ) , alfacalcidol , and calcitriol had no statistically significant effect on mortality .
Vitamin D(3 ) combined with calcium significantly increased nephrolithiasis .
Both alfacalcidol and calcitriol significantly increased hypercalcaemia
BACKGROUND The available evidence on vitamin D and mortality is inconclusive .
OBJECTIVES To assess the beneficial and harmful effects of vitamin D for prevention of mortality in adults .
Calcium-vitamin D3 supplementation is cost-effective in hip fractures prevention.
OBJECTIVE To assess the cost implication s for a preventive treatment strategy for institutionalised elderly women with a combined 1200 mg/day calcium and 800 IU/day vitamin D(3 ) supplementation in seven European countries . DESIGN Retrospective cost effectiveness analysis based on a prospect i ve placebo-controlled r and omised clinical trial . DATA SOURCES Recently published cost studies in seven European countries . Clinical results from Decalyos , a 3-year placebo-controlled study in elderly institutionalised women . TRIALS Decalyos study , with 36 months follow-up of 3270 mobile elderly women living in 180 nursing homes , allocated to two groups . One group received 1200 mg/day elemental calcium in the form of tricalcium phosphate together with 800 IU/day ( 20 microg ) of cholecalciferol ( vitamin D(3 ) ) , the other placebo . RESULTS In the 36 months analysis of the Decalyos study , 138 hip fractures occurred in the group of 1176 women , receiving supplementation  and 184 hip fractures in the placebo group of 1127 women . The mean duration of treatment was 625.4 days . Adjusted to 1000 women , 46 hip fractures were avoided by the calcium and vitamin D(3 ) supplementation . For all countries , the total costs in the placebo group were higher than in the group receiving supplementation , result ing in a net benefit of 79000 - 711000 per 1000 women . CONCLUSION This analysis suggests that the supplementation strategy is cost saving . The results may underestimate the net benefits , as this treatment has also shown to be effective in decreasing the incidence of other non-vertebral fractures in elderly institutionalised women
