25-Hydroxyvitamin-D3 serum modulation after use of sunbeds compliant with European Union standards: A randomized open observational controlled trial


Weber, Benedikt; Bachmann, Chantal C; Braun, Ralph; Abraham, Alison G; Serra, Andreas L; Hofbauer, Günther F L (2017). 25-Hydroxyvitamin-D3 serum modulation after use of sunbeds compliant with European Union standards: A randomized open observational controlled trial. Journal of the American Academy of Dermatology, 77(1):48-54.

Abstract

BACKGROUND: Regular use of sunbed exposure has been reported to increase 25-hydroxyvitamin-D3 [25(OH)D] serum levels. However, the influence of sunbeds compliant with the recent European Union standard EN-60335-2-27 on 25(OH)D serum levels is unknown.
OBJECTIVE: We investigated the impact of standard sunbed use compliant with the European Union standard on 25(OH)D serum modulation and well-being.
METHODS: In a randomized controlled study, 25(OH)D serum levels were measured at enrollment, after 1 week, and after completion of the 12-week period of sunbed use with twice weekly exposure and compared with the control group without any sunbed exposure.
RESULTS: In the sunbed intervention group (N = 31), a 27% increase of mean 25(OH)D levels was noted 1 week after starting sunbed use (P < .01). However, after 12 weeks, mean 25(OH)D levels had declined and were no longer different from baseline (P = .06). After 12 weeks, 25(OH)D levels did not differ between the intervention and control group (P = .36). Also the 5-item World Health Organization Well-Being Index score did not differ between the sunbed and control groups (P = .19).
LIMITATIONS: For ethical reasons recruitment was limited to persons actively seeking sunbed exposure.
CONCLUSIONS: Standard use of sunbeds compliant with the European Union standard induced a transient increase of 25(OH)D levels, whereas no change in well-being was observed.
