Economic modelling

The economic model addressed the question: 'What is the most cost-effective way of providing vitamin D to specific population groups (pregnant women, children under 5 years, people aged 65 or over and people whose skin is darker)?' There were not enough data to model this question for 'people whose skin is not sufficiently exposed to the sun'.

There were 2 sets of analysis. The first compared the cost of providing each group with a daily supplement (without testing for deficiency) with the cost of testing everyone and giving those with a deficiency a supplement.

The second analysis looked at increasing uptake of supplements among pregnant and breastfeeding women, and among children up to the age of 5.
