Sun exposure provides inadequate vitamin D in UK adolescentsFarrar MD, et al. J Clin Endocrinol Metab. 2016;doi:10.1210/jc.2016-1559.
Adolescents in the United Kingdom did not get enough sunlight to receive healthy amounts of vitamin D in a study recently published in The Journal of Clinical Endocrinology & Metabolism, prompting researchers to recommend changes to British government guidelines on vitamin D intake. More than one-quarter of the adolescents in the study had inadequate vitamin D levels even during summer, the period when participants spent the most time outdoors.
“Current U.K. national guidance on vitamin D acquisition assumes those aged 4 to 64 years gain their vitamin D requirements from sunlight alone, thus there is no recommended nutrient intake,” Mark D. Farrar, BSc, PhD,of the Centre for Dermatology, Institute of Inflammation and Repair, University of Manchester, and colleagues wrote. “Meanwhile, substantial proportions of the global population, including the U.K., are reported to have low vitamin D status, and rickets has returned as a clinical concern.”
