The deficiency of micronutrients, including vitamin D, is frequent in several countries, regardless of the nutritional state, however, it’s magnitude is higher in overweight children¹. There are many evidences that overweight children and teenagers represent a vulnerable group to vitamin D deficiency. Besides that, the deficiency of vitamin D appears to be the biggest contributory factor to complications associated to obesity, such as insulin resistance and type 2 diabetes.² Various studies have been demonstrating associations between deficiency of vitamin D and a variety of diseases, including diabetes mellitus, metabolic syndrome, cancer, cardiovascular diseases, multiple sclerosis and neuromuscular malfunction, causing nutritional rickets and osteomalacia, which have a major impact on health, growth, and development of infants, children, and adolescents4 (Figure1). The main goal of this study is to evaluate the prevalence of hypovitaminosis D and intervene by providing adequate supplementation5. Methodology & Theoretical Orientation: Serum dosages of 25-OHD3 and PTH (parathyroid hormone) were performed in 111 overweight/obese children, on the month of March (summer) of 2016. All of the children that were detected with insufficiency (<29ng/ml) received supplementation on the dosage of 50.000 UI of Cholecalciferol/ weekly, during six weeks. Findings: The prevalence of hypovitaminosis D in this group was of 60,36% (49,24% girls e 50,7% boys). Conclusion & Significance: Hypovitaminosis D is elevated on the presented group, meeting other studies performed in various locations in Brazil and foreign countries. The fact that dosages were performed in a period that coincided with the end of the summer calls our attention. Supplementation was performed in a critic period to elevation of taxes of hypovitaminosis D (beginning of winter).

Dr. Tatyana Bairova graduated from Tomsk Medical Universitety as a Pediatrician. After that she went on to complete her post-graduate study at Scientific Centre for Family Health and Human Reproduction Problems (SC FHHRP, Irkutsk, Russian Federation) where she has stayed as a specialist and a researcher until today.

Statement of the Problem: Among the causes of obesity an important role is played by the heredity. The FTO is one of the genes associated with obesity and body mass fat. And polymorphism rs9939609 of this gene located in the first intron (the code is W = A/T) appears the most significant.rn Methodology & Theoretical Orientation: The study included total of 128 Caucasian female adolescents (average age 15.86±1.02) living in Eastern Siberia (Irkutsk region, Russia). SDS BMI, % of body mass fat was measured. 59 girls were included in group with normal weight (SDS BMI 0.84±0.55) and 69 girls were included in group with overweight and obesity (SDS BMI 2.52±0.72). Genomic DNA was extracted from EDTA-treated whole blood by commercial kits (DNA-Sorb-B, AmpliSens, Russia). Genotyping of the FTO rs9939609 was performed using polymerase chain reaction in real time with DT-Prime cycler (DNA-technology, Russia). Statistical analysis was performed by soft “STATISTICA8.0”. rnFindings: A-allele frequency was 40% in control group and 49% was in group with overweight and obesity (р=0.223). Comparisons of SDS BMI and percent of body mass fat stratified by FTO rs9939609 genotypes are showed in Table 1. We found the significant increase of SDS BMI in carriers of A-allele in group with overweight and obesity. There is no this association in group with normal weight.rn Conclusion & Significance: Thus, carrier of the A-allele of FTO rs9939609 are associated with higher meaning of SDS BMI in female adolescents with overweight and obesity, living in
