Primary Outcome Measures

Name	Time	Method
Vitamin D levels are measured using blood spot sampling at the start and end of each 21 day epoch. The extent and direction of the change will be compared between groups in each of the high UV and low UV seasons using standard statistical methods, including comparison of mean levels of 25(OH)D change, comparison of proportion in each group whose levels increase or decrease; and within individual comparisons for intervention and control periods, which will control for differences between individuals in response to UV exposure. Secondary analyses will include additional comparisons of the level and direction of change in high and low UV periods in relation to geographic area of study (Scotland or England), different types of targeted intervention, and directly to the responses to the behavioural (i.e. TPB) and risk knowledge questionnaires

Secondary Outcome Measures

Name	Time	Method
Behavioural change is measured using the Theory of Planned Behaviour at the start and end of each 21 day epoch. During the summer periods, we additionally measured personal exposure to UV radiation.
