As residents of a tropical country, Indonesia should not be deficient in vitamin D. The sun being the main source of ultraviolet rays that make vitamin D beta so vitamin is abundant in the archipelago.
However, increasing the number of buildings in the hustle and bustle of big cities make a lot of kids tend to lose a nutritious morning sunlight. They had to leave before the sun rises to avoid congestion and not many open spaces to play in the home and school environment.
In the big cities, especially in the middle-class safety and environmental concerns make their children are rarely allowed to play outside the house. When the weekend was a lot more kids are invited to the mall, there are also available especially playing facilities.
efficacy large
In fact, the efficacy of vitamin D so extraordinary. A study published in December in the journal Dermato-Endocrinology mentioned, vitamin D helps reduce the risk of developing autism.
Research in several states of the United States took place in 2010 in children aged 6-17 years with varying levels of autism prevalence. Apparently, in those states that many irradiated ultraviolet beta, only half of the cases of autism states that limited summer.
It is not surprising that concerns about vitamin D deficiency continues to increase, particularly those not exposed to the sun all year round. November a month vigilance even vitamin D and various studies conducted with surprising results.
Professor Mitch Blair of the Royal College of Paediatrics and Child Health, UK, December writing in BBC News that half of the number of children and 90 percent of the adult multiethnic population living in the UK are deficient in vitamin D.
Vitamin D deficiency is known to be associated closely with the emergence of a variety of health problems in children and adults, such as diabetes, tuberculosis, multiple sclerosis, and rickets: bone disorders that are often found in poor children in the UK.
In New Zealand a lot bathed in sunlight, there Massey University who examined the vitamin D status of children with funding from the Health Research Council of the country. Children aged 2-4 years were recruited during August and September 2012 to see the correlation of vitamin D adequacy with respiratory disorders, skin diseases such as eczema, and allergies.
Research in New Zealand is also important to measure the sun's role in formation of vitamin D because almost all foods in the country are still free from the fortification of vitamin D. Although vitamin D is also found in some foods such as oily fish, eggs, and mushrooms, whereof only 10 percent of the recommendation for adequate intake.
Vitamin D is classified as a steroid hormone production and metabolism lasted just when the skin is exposed to ultraviolet light beta. Throughout three decades, vitamin D deficiency is associated with various diseases such as cancer, cardiovascular disorders, autoimmunity, and diabetes. However, researchers at Massey University also proved that vitamin D deficiency can lead to insulin resistance which raises diabetes mellitus type 2.
intervention efforts
According to Professor Mitch Blair, efforts to overcome the deficiency of vitamin D should be done in various ways, ranging from providing vitamin D supplements are widely and cheaply to vitamin D fortification in various foods and beverages.
The results of the study Professor Marlena Kruger, still from Massey University, which took place in Jakarta, Indonesia, and Manila, Philippines, during the year 2007-2008, showed that fortification of vitamin D deficiency is significantly reduced.
In this study, post-menopausal women respondents were asked to drink milk that has been fortified with vitamin D, magnesium, and zinc, whereas respondents drank a placebo containing only control serum parathyroid hormone. Vitamin D levels were measured before and after respondents intervention.
As published in the scientific journal Bone volume 46, March 2010, the results showed that women who drank milk fortified vitamin D deficiency decreases it. In Indonesian women, deficiency dropped from 70 percent to 22 percent and in women in the Philippines dropped from 20 percent to 0 percent. Milk fortified with vitamin D, magnesium, and zinc also successfully increased levels of osteocalcin in the eighth week from 18 percent to 25 percent. Procollagen type I N-propeptide (PINP) also increased in the eighth week from 15 percent to 21 percent.
Both these compounds play a role in bone formation. That is, drink milk regularly, especially those who have fortified-help strengthen bones and prevent osteoporosis.
need socialization
Therefore, the socialization role of vitamin D is important. Although Indonesia gets sun most of the year, the above results indicate that there are still many people who have vitamin D deficiency, especially women.
So, first of all people need to understand the role of vitamin D, the impact if any shortfall, and then ways to get adequate vitamin D. The health workers, including health educators, nurses, and doctors, must understand the symptoms of vitamin D deficiency and how to overcome them.
From an early age, children should also be encouraged to move out of the room. Therefore, the presence of open space that is safe and comfortable to be important for beta ultraviolet blessing is not in vain.
