I’m not sure this new report on the association between hearing loss and depression in older Hispanic people in JAMA Otolaryngology adds much to our knowledge of how hearing loss affects people. It has been known for some years that hearing loss is associated with depression in older people. The report extends the research to Hispanic people in several large cities, but as best as I can tell, that’s the only new information. The authors claim that this study’s importance is that it measured hearing loss rather than relying on reports of hearing difficulties, but some earlier studies did that, too.
In older people it’s hard to tell if the hearing loss was caused by noise or not, because over time changes indicating hearing loss from noise lose specificity as hearing loss becomes worse. But my analysis of the literature suggests that what is commonly called age-related hearing loss, as in the JAMA Otolaryngology article, is really noise-induced hearing loss, which is entirely preventable.
Now that the connection between hearing loss and depression is clear, doesn’t it make sense for government and the medical community to commit resources to educate the public about the dangers of noise-induced hearing loss? A host of health concerns will diminish or disappear if we focus on stopping noise-induced hearing loss.
