Abstract: Objective: To assess vitamin D status among Cypriot adolescents and investigate potential determinants including BMI and body fat percentage (BF%). Design: Participants had cross-sectional assessments of serum vitamin D, physical activity, dietary vitamin D intake and sun exposure. Linear and logistic regression models were used to explore the associations of vitamin D with potential predictors. Setting: Hospitals, Cyprus, November 2007-May 2008. Subjects: Adolescents (n 671) aged 16-18 years. Results: Mean serum vitamin D was 22•90 (sd 6•41) ng/ml. Only one in ten children had sufficient levels of vitamin D (≥30 ng/ml), while the prevalence of vitamin D deficiency (12-20 ng/ml) and severe deficiency (<12 ng/ml) was 31•7 % and 4•0 %, respectively. Lower vitamin D was associated with winter and spring season, female gender, reduced sun exposure in winter and darker skin. Participants with highest BMI and BF% when compared with a middle reference group had increased adjusted odds of vitamin D insufficiency (OR = 3•00; 95 % CI 1•21, 7•45 and OR = 5•02; 95 % CI 1•80, 13•97, respectively). A similar pattern, although not as strong, was shown for vitamin D deficiency with BF% (OR = 1•81; 95 % CI 1•04, 3•16) and BMI (OR = 1•51; 95 % CI 0•85, 2•67). Participants in the lowest BMI and BF% groups also displayed compromised vitamin D status, suggesting a U-shaped association. Conclusions: Vitamin D deficiency in adolescence is very prevalent in sunny Cyprus, particularly among females, those with darker skin and those with reduced sun exposure in winter. Furthermore, vitamin D status appears to have a U-shaped association with adiposity measures.
