In the United Kingdom (UK). There is a lack of research looking at vitamin D status of the British African-Caribbean population. This population is particularly at risk to vitamin D deficiency due to possessing a skin type which hinders the production of vitamin D in the skin. Further, due to the geographical location of the UK, there is reduced ability to produce vitamin D due to the low sun exposure (Libon 2013 ). Our main source of vitamin D is through skin exposure to the sun. In the UK, the UV radiation is only strong enough in April-September (Wilson 2017) for the production of vitamin D to occur. In winter months, vitamin D needs to be consumed in food or supplement form. Vitamin D is essential for healthy bones and is associated with reduced risk of certain cancers and immune disorders (Wilson 2017). There is strong epidemiological evidence linking low vitamin D status with diabetes, cardiovascular disease, osteoporosis, osteoarthritis and some cancers (NatCen 2018).\n\nThis observational study will aim to determine the vitamin D status of British Afro-Caribbean women, as well as determine the effects of sun exposure, dietary vitamin D intake, muscular strength, lifestyle and anthropometrical (height, weight etc.) factors have on vitamin D status. The study will be conducted at the University of Surrey. The study will take place in Autumn and winter 2019\u002F2020 and a repeat study in Spring 2020. Each participant will require two visits to the university, each session will take approximately 2 hours. The study is funded by the University of Surrey. The findings of this study may lead to strategies for improving vitamin D status in this population, as well as improving guidelines to assist darker-skinned people regarding sunlight exposure in high latitudes.",[50],"Vitamin D Deficiency",[52,53],"vitamin D OR 25(OH)D","African-Caribbean OR Afro-Caribbean","2024-12-11",{"date":56,"type":57},"2024-12-16","ACTUAL",{"date":59,"type":57},"2020-02-07",{"date":61,"type":46},"2025-03-31",{"name":5,"class":6},1]
