Korea is located in the northern hemisphere, and people often use sunscreen and little outdoor activities. On the other hand, unlike foreign countries, there are very few vitamin D-fortified foods such as vitamin D-fortified milk, so children and adolescents are at high risk for vitamin D deficiency.
According to the 2014 National Health and Nutrition Survey, the average level of vitamin D in children and adolescents aged 10 to 19 is a deficiency level of only 16 ng/ml.
Vitamin D deficiency is approaching dangerous levels as children and adolescents are unable to play outside in the sun, their physical strength is degraded due to neglect of physical education in school education, and more indoor life due to Corona 19 due to’knots’. .
Vitamin D is essential for the formation of bones and muscles, so it is essential for the growth of children, but it can also prevent special diseases. It is believed that vitamin D is related to the immune response and regulates inflammation. Representatives are atopic dermatitis and otitis media, and studies have shown that vitamin D prevents or alleviates these diseases. Some papers have concluded that data and research results are still lacking, so more extensive research is needed, but few scholars deny the effectiveness.
Atopic dermatitis=According to a 2011 study by a pediatric research team at the Medical University of Verona, Italy, children aged 5-6 years with atopic dermatitis were found to be more severe with lower blood levels of vitamin D.
In 2013, a research team at North Carolina Medical University and a research team at Warsaw Medical University in Poland announced that when atopic patients with very low vitamin D blood levels were given 2,000 IU of vitamin D per day for 3 months, 90% of them showed remarkable improvement.
Some studies have shown that winter atopy can be treated with 1,000 IU of vitamin D. In 2014, as a result of a joint study on vitamin D administration for atopic dermatitis in the Harvard University Medical School and the Mongolian Medical University, the atopic index (EAST) of the administration group and the placebo group was statistically significant as -6.6 vs -3.3.
Vitamin D stimulates macrophages, which are immune cells, to secrete cathelicidin, a physiological antibiotic that removes all viruses, bacteria and fungi. Cathelicidin, a natural antibiotic, can prevent atopic dermatitis from worsening because it inhibits staphylococcus, which worsens atopy.
In order to prevent atopy and promote treatment, it is necessary to first consider the vitamin D blood concentration rather than the clinical dose above, find a dose that can maintain 40-60 ng/mL, and continue taking the amount.
Otitis media=Acute otitis media in children is a common reason for parents to visit hospitals with their children, and it can interfere with study by distracting elementary school students from focusing on class.
In 2013, a research team from the Milan Medical University, Italy, compared children aged 1-5 years old who had acute otitis media at least four times, divided into groups taking vitamin D and those who did not. Acute otitis media recurred in 50% of the non-vitamin D group, whereas only 17% relapsed in the 1,000 IU daily vitamin D group. In this comparative experiment, the vitamin D dose group had a blood level of 26.5 mg/mL at first, as in the non-dose group, but after 4 months, 75% reached a normal level of 30 ng/mL. When the two results are combined and reinterpreted, vitamin D blood concentrations exceeding 30 ng/mL may show acute otitis media prevention.
The causes of acute otitis media are known to be viruses in 25% and bacteria in 75%. However, bacterial otitis media is often infected with the virus and then the bacteria invade. Vitamin D’s endogenous immune function prevents acute infection of these viruses and bacteria. When viruses, bacteria, fungi, etc. invade, vitamin D activates the gene to synthesize cathelicidin, which removes viruses, bacteria or fungi of any kind.
Therefore, children and adolescents should also maintain blood levels of vitamin D from 40 to 60 ng/mL to prevent various diseases and promote treatment. Depending on your age and weight, it is recommended that you take 2,000 IU to 5,000 IU every day for 3 to 4 months, and then perform a vitamin D level test to adjust the dose.
