A new study from Hasbro children's Hospital stated that the most obese young people in vitamin d lack the researchers call for intensified monitoring of vitamin D levels in this population, and for further studies to determine whether vitamin D levels will normalize to reduce the health risks associated with obesity. The study is published in the may issue of the journal of adolescent health, and is available online in advance of the print.
Obesity in children and young people has reached epidemic proportions, with a prevalence of 16.4 per cent under 10, 17-year-old in 2007. The increased prevalence of obesity can lead to increased risk of diabetes, high blood pressure and cardiovascular disease, as also an increased risk of cancer. Some of these health consequences of obesity also vitamin D deficiency or insufficiency allocated. Additionally, vitamin D muscle power/force is significantly associated with status, and therefore a deficiency can affect obese youth physical activity to increase.
Lead author Zeev Harel, m.d., a physician specializing in adolescent medicine Hasbro children's Hospital, reported that screening obese young people for vitamin D status by measuring their blood 25 OH D level a routine Protocol of the adolescent health center of Hasbro children's Hospital in Providence has become istR.I. Since 2007.
For this retrospective study of Harel and his co-authors explored the prevalence of low vitamin D status among 68 obese young people, and examines the impact of the treatment of low vitamin D status in these patients.
The study found that low vitamin D status in all of the girls (72 percent defective and inadequate 28 per cent) and in 91 percent of the young (69 percent defective and 22 percent not enough) was. You with vitamin D deficiency or insufficiency had a repeated measurement of vitamin D level 43 patients after treatment. While there was a significant increase in the vitamin D levels after treatment, normal serum vitamin D levels in only 28percent of these patients. Repeat several courses of the vitamin D treatment in the patients that normalize not their vitamin D levels after initial course, their low vitamin D status could not be normalized.
Harel says "The prevalence of low vitamin D status among obese young people in this study is larger than previously reported for this age group." It is us on, normal vitamin D levels through a course which could normalize treatment of the recommended dose of vitamin D, while the other 72 percent with repeat their levels treatments could only 28 percent of young people "." Vitamin d can be seized in body fat and this is probably the main reason for the lack of response.
The most important source of vitamin D is the production in the skin; a process stimulated by sunlight. In addition, small amounts come from certain foods such as fatty fish, eggs, and fortified foods such as dairy products and cereals. The researchers State, "it is possible that the association between obesity and low vitamin D status indirect, in obese people with less outdoor activities than a slim person, and therefore less exposure to Sun." "Also, it is also possible that obese people eat food not enough to do that the vitamin D".
The researchers question whether a higher daily vitamin-D intake than those recently by the Institute of medicine recommended (600 international units of vitamin D per day) as in an attempt to increase their vitamin D status part of the treatment in obese adolescents, might require. Harel says, "It remains future studies to determine whether certain conditions such as obesity require to prevent a higher cut-off of vitamin D blood levels in an attempt of the health consequences of obesity."
"Based on the results of this study, increased monitoring of obese young people we call for their vitamin D levels after first course of treatment not normal." In addition, prospective studies are needed to assess whether the normalization which is health risks associated with obesity vitamin D levels in obese young people reduction, "says Harel."
