Link Between Hearing Loss And Iron Deficiency Anaemia
People with iron deficiency anaemia have more than twice the rate of hearing loss as people without the disorder.
Pennsylvania State University College of Medicine in the US came to this conclusion after examining more than 300,000 adults with hearing loss.
When the researchers looked at the types of hearing loss, the overall risk for sensorineural hearing loss in people with iron deficiency anaemia was 82% higher than for someone without the blood condition.
The risk of a mixed hearing loss (a combination of sensorineural hearing loss and conductive hearing loss) was 240% higher than for people without iron deficiency anaemia.
According to the author the study only shows a connection between hearing loss and iron deficiency anaemia. The study does not prove that the one causes the other.
In the study the researchers checked the prevalence of hearing loss in more than 300,000 adults from 2011 to 2015. The adults were between the ages of 21 and 90, with an average age of 50. 56.6% were women, 43.4% were men.
The study was published in the journal JAMA Otolaryngology – Head & Neck Surgery.
