Furthermore, significant evidences also relates this phenomenon to behavioral, dietary and genetic factors, since, in regions of high sun exposure, habits such as excessive sunscreen use, low consumption of dietary sources of vitamin D, or the genetic predisposition of individuals could contribute to the increase of hypovitaminosis D in these places 12, In addition, a negative association between calcidiol and BMI Z -score is observed, as reported previously.

The main strength of this study is that it was carried out in a cohort of healthy children that have been followed up from the prenatal period. Canned tuna, sardines or mackerel.

Yin K, Agrawal DK. In addition, the criteria used to evaluate the sun exposure of adolescents may have been a little too specific to that function, requiring validated studies comparing different measures of sun exposure according to age groups, since the habit of sun exposure may vary with age. Therefore, we need to promote effective exposure to sunlight in children residing hipoviyaminosis Asturias.

In order to ensure an effective exposure, there should be an emphasis on hipovitaimnosis a minimum of 10—15 min in the sun without protection, at least in the arms and legs, in the spring, summer and autumn. We found no association between time outdoors and 25 OH D3 levels Table This reduction in the levels of serum calcidiol coinciding hipovitwminosis increased adiposity is assumed to be due to enhanced sequestration of vitamin D in fat, a factor leading to decreased bioavailability.

Serum calcium was carried out by automated colorimetric technique using Calcium Arzenazo commercial kits Bechman Coulter according to the manufacturer’s guidelines.

Low levels of vitamin D in some autoimmune and chronic diseases may be attributed to insufficient outdoor activities due to present diseases i. The identification of potentially associated factors may contribute to the prevention of various diseases in adulthood that have their pathophysiology related to hypovitaminosis D.

Thyroid stimulating and 1. Due to the deficit of intake in childhood, recommendations are needed about a varied diet with vitamin D-containing foods in this age group, especially during the winter, and assessing the need of vitamin D supplementation in children at risk. On the other hand, a study conducted in infants in Asturias found no evidence to support routine supplementation in this age group, although the authors underscored the importance of strictly monitoring exclusively breastfed infants, especially in the winter and in the early months of life.

We did not find an association between BMI and 25 OH D3 levels, which was not consistent with the findings of other studies conducted in children that showed a correlation between obesity and a higher prevalence of vitamin D deficiency.

From September to the end of November, blood samples were obtained from all individuals and vitamin D levels were analyzed.

We must make this known both to the general population and to health care professionals, given the importance of maintaining an adequate vitamin D status.

Future studies should focus on the utilization of vitamin D for reducing symptoms and preventing HT as well as hipofitaminosis its protective roles.
