Vitamin D also called as the sunlight vitamin is linked with asthma from indoor pollution among children living in urban environments. Such urban environments showcase high levels of indoor air pollution.
Researchers from the Johns Hopkins University School of Medicine in Maryland learned that low levels of vitamin D were linked with respiratory problems caused due to indoor air pollution among obese children in urban areas.
The study investigated 120 children over 9 months in the Baltimore area. They tested the vitamin D levels in the children’s blood, their asthma symptoms, and the levels of air pollution in their houses.
Of the 120 children involved in the study all had preexisting asthma and 1/3 of these children were obese. These researchers found that children living in homes with the highest levels of indoor air pollution and were also obese with high blood levels of vitamin D showed fewer-asthma related symptoms.
Put simply, researchers noted that vitamin D had a protective role to play when it comes to vitamin D.
The Impact On African – American Children
As per the Centre for Disease Control and Prevention, about 6.1 million children in the US have asthma. Asthma affects urban minorities including children from the African-American children.
Several factors chip in the burden of asthma among urban blocks. The culprits include environmental factors like pollution, obesity, poor diet, genetics, and so on. Vitamin D deficiency is also disproportionately present among black children.
This could possibly be due to poor diet and darker skin pigmentation that blocks production of vitamin D as compared to lighter skin tones. In 2015, it was reported that 2.6 million non-hispanic blacks revealed having asthma. In the year before that, African-Americans were nearly at a three times increased risk of dying from complication from asthma than their white counterparts.
African-Americans children are also at four times increased odds of going to the hospital due to asthma than white children.
The Link Between Asthma And Vitamin D
This research brings to light the relationship between asthma and vitamin D. In a previous study, researchers compared vitamin D levels, asthma diagnoses, and lung function in 10,000 children and over 24,000 adults.
They learned that low levels of vitamin D were linked with a diagnosis of asthma and declined lung function as well. Essentially, it is well established that vitamin D is responsible for amping up bone strength. However, researchers learned that the vitamin plays a crucial role in producing insulin and in the working of the immune system.
Experts opines that vitamin D not only influences asthma among obese children living in urban environments but also overall health wellbeing. Several studies also show that vitamin D assists not only asthma but other inflammatory conditions.
In a nutshell, vitamin D is essential not only for bone health but also for keeping asthma and other inflammatory conditions at bay. As per this study, vitamin D can impact asthma among obese children living in urban areas with significant levels of indoor pollution.
