Washington : Most obese adolescents are deficient in vitamin D, which may increase their risk of diabetes, hypertension, cancer, and cardiovascular disease, according to new study.
Researchers at Hasbro Children''s Hospital have called for further studies to determine if normalizing vitamin D levels will help to lower the health risks associated with obesity.
Lead author Zeev Harel and his team explored the prevalence of low vitamin D status among 68 obese adolescents, and examined the impact of treatment of low vitamin D status in these patients.
They found that low vitamin D status was present in all of the girls (72 percent deficient and 28 percent insufficient) and in 91 percent of the boys (69 percent deficient and 22 percent insufficient).
Of those with vitamin D deficiency or insufficiency, 43 patients had a repeat measurement of vitamin D level after treatment. While there was a significant increase in vitamin D levels following treatment, serum vitamin D levels normalized in only 28percent of these patients.
Repeat multiple courses of vitamin D treatment in the patients who did not normalize their vitamin D levels after initial course, failed to normalize their low vitamin D status.
The researchers explained that Vitamin D may be sequestered in body fat and this likely is the major reason for the lack of response.
The study has been published in the May edition of the Journal of Adolescent Health.(ANI)
