Access from EThOS:
Vitamin 0 is predominantly obtained from cutaneous synthesis following sun exposure, as good dietary sources are limited. Low vitamin 0 status (25-hydroxyvitamin D (25(OH)D) <80nmol/l) has been observed in countries at high latitudes, where cutaneous synthesis is insufficient for half of the year. Vitamin 0, or more specifically, the active form, 1,25- dihydroxyvitamin 0 (l,25(OHhO), plays a role in calcium homeostasis and immunomodulation, and is involved in the pathogenesis ofosteoporosis, obesity and autoimmune diseases such as multiple sclerosis (MS).This thesis examined the vitamin D intake and status ofpopulation subgroups in Northern Ireland (latitude 55~) through an intervention study (healthy adults), a case-control study (MS patients), an epidemiological study (adolescents) and a cross-sectional observational study (overweight women).
