According to a new study, vitamin D deficiency and insufficiency is widespread among adolescents living in the Emirates.
In the observational study, serum concentrations of 25-hydroxy vitamin D were measured in blood samples of 315 healthy adolescents from eight schools in Al Ain, Abu Dhabi Emirate (1). The study results showed that 19.7% of the participants were vitamin D deficient (concentration below 15 ng/mL resp. 37.5 nmol/L).
In addition, 45.4% had insufficient levels (below 20 ng/ml resp. 50 nmol/l). The prevalence of vitamin D deficiency varied between boys (10%) and girls (28%).
The researchers concluded that the prevalence of vitamin D deficiency in adolescents in the UAE is very high, particularly in females, compared to their counterparts in other developed countries where vitamin D fortified foods are available, and people use vitamin D supplements. Although the UAE and other Gulf countries have a sunny environment, skin sun exposure is low as both adult and adolescent females observe conservative dress codes that either require covering all body parts including face and hands (Niqab) or all body parts except the face and hands (Hijab). Inadequate nutritional intake of vitamin D may further contribute to low vitamin D concentrations. Therefore, vitamin D deficiency remains one of the major public health problems in this part of the world.

Cardiovascular health relates to the health of the heart, the blood vessels and the organs that are critically dependent on a strong blood supply. A smoothly functioning cardiovascular system is crucial to good overall health as every cell of the body depends on its function for survival. Accordingly, disorders of the cardiovascular system can have far-reaching effects.

A new review from France suggests that existing study data indicating that increased blood vitamin D concentrations are associated with a reduction in the risk of chronic diseases, such as cardiovascular events, diabetes and related mortality, does not prove that vitamin D supplementation can prevent those diseases. Experts commented that, although evidence in non-bone-health-related chronic disease prevention is missing, there is good reason to ensure that the vitamin D supply is adequate.
