Notes : عنوان به فارسی : بررسی ارتباط سطح ویتامین‭ D‬با شیوع سندرم متابلیک درنمونه منتخب کودکان و نوجوانان‭ ۲۷ ‬استان ایران در سال‭۱۳۸۸ - ۸۹ ‬
Notes : As the first nationwide study in the Middle East and North Africa (MENA), this study aimed to investigate the association of serum 25 hydroxy vitamin D [25(OH)D] levels with cardiometabolic risk factors in a nationally representative sample of the pediatric population in Iran. The second objective was to provide the prevalence of hypovitaminosis D and the percentiles of serum 25(OH)D in the study population. This national population-based study was conducted among 1100 Iranian students living in 27 provinces in Iran. The association of 25(OH)D with each cardiometabolic risk factor was determined after adjustment for age, gender, body mass index, and waist circumference. Participants consisted of 1095 students (52 boys) with a mean age of 14.74 +- 2.61 y. The median of 25(OH)D level corresponded to a vitamin D insufficiency level; it was 12.70 ng/mL in boys and 13.20 ng/mL in girls. Overall, 40 percent of participants were vitamin D deficient, and 39 percent had vitamin D insufficiency. There were no significant differences in these findings between boys and girls. Adjusted regression analysis revealed a significant weak inverse association of 25(OH)D with systolic blood pressure, diastolic blood pressure, total cholesterol, and low-density lipoprotein cholesterol. This association was significantly positive with high-density lipoprotein cholesterol but not with fasting plasma glucose and metabolic syndrome. We found a considerably high prevalence of hypovitaminosis D in the pediatric population of a sunny region. Our findings also revealed an association of hypovitaminosis D with many cardiometabolic risk factors from childhood; these associations were independent of obesity indexes. It is of special concern that the highly prevalent disorders of low 25(OH)D and low highdensity lipoprotein cholesterol in children and adolescents of the MENA region had significant association. The clinical importance of our findings needs to be confirmed in longitudinal studies.
