The research team led by Professor Song Kyung-cheol of the Department of Pediatrics at Yongin Severance Hospital found a correlation between vitamin D and bone density and lipid levels in adolescents. Professor Song’s team advised on the 15th that “a significant number of Korean children and adolescents were found to be vitamin D deficient.” “It is necessary to secure sufficient sunlight and supplement it through nutritional intake.”
Vitamin D is a hormone that regulates calcium and bone metabolism and is known to be associated with cardiovascular diseases, tumors, and autoimmune diseases. However, studies on vitamin D deficiency in children and adolescents who are not adults have been very limited.
Professor Song’s team studied data from the 2009-2011 National Health and Nutrition Examination Survey and found that adolescents (ages 12 to 18) who did not have sufficient vitamin D levels in the body had low bone density. In particular, even after adjusting for variables such as calcium intake, physical activity time, body mass index, body fat mass, and lean mass, vitamin D levels still showed a linear relationship with bone density, confirming that vitamin D had a direct correlation with bone density.
In addition, according to the results of the 2008~2013 National Health and Nutrition Examination Survey, among adolescents (12-18 years old), the vitamin D-deficient group was more likely to have hypo-HDL dyslipidemia, a lowering of HDL (High Density Lipoprotein) than the sufficient group. The prevalence was found to be high.
In normal-weight boys, the prevalence of low HDL dyslipidemia was 17% in the vitamin D-sufficient group compared to 12% in the vitamin D-sufficient group. done. As dyslipidemia is considered one of the risk factors for cardiovascular disease, management is essential.
In addition, Professor Song’s team confirmed that a significant number of children and adolescents in Korea suffered from vitamin D deficiency. The average vitamin D (25-hydroxyvitamin D) level of Korean children and adolescents was 16.28 ng/ml, which was lower than that of 25.6 ng/ml in the United States, and the vitamin D deficiency rate in Korean children and adolescents was 79.3%, which is similar to that of the United States (about 50%). was very high compared to
Professor Song said, “I think this study is of great significance to reveal the correlation between the health of children and adolescents and vitamin D, which has been limited in previous studies.”
