Statistics of Childhood Hearing Loss

According to the American Speech Language Hearing Association, “the number of Americans with a hearing loss has essentially doubled during the past 30 years.” For children in particular, the number has grown from 13.2 million in 1971 to 24.2 million in 1993.

In more recent years, the number has grown. Healthy Hearing writes, “Unfortunately, hearing loss is becoming more commonplace in youth due to the noise in our environment. In 2013, the Centers for Disease Control and Prevention (CDC) estimated that at least 12.5 percent of children and adolescents ages six to 19 have suffered permanent damage to their hearing due to excessive noise exposure.”

Hearing loss may affect anyone at any age. Though it has long been associated with older adults, there has been an increase of hearing loss in children.

Causes of Childhood Hearing Loss

Otitis media

Otitis media is more commonly known as an ear infection. This creates an inflammation in the middle ear (behind the eardrum) and causes a buildup of fluid. Ear infections are very common in children, due to the size and positioning of the Eustachian in tube. In children, the Eustachian tube is quite small and more horizontal than in adults. As such, it is easily blocked with infection. Most children will experience an ear infection before their third birthday.  Ear infections are the most common cause of hearing loss in children, as the fluids produced may cause permanent damage.

Congenital conditions

Congenital hearing loss refers to hearing loss caused by genetic conditions present at birth. This form of hearing loss makes up 50% of hearing loss cases in children. Hearing loss may be passed on as a gene from parents, in the case of autosomal dominant hearing loss. If one parent carries the dominant gene and has hearing loss, there is a 50% chance the child will acquire it. If both parents have this gene, the probability is higher. In a recessive case, the chances diminish. Another form of genetic hearing loss is X-linked hearing loss, in which the mother passes on a recessive trait for hearing loss on to male children (not female). Syndromes such as Down, Usher, Treacher Collins, and Crouzon may affect hearing as well.

Acquired hearing loss

As with otitis media (above), children may acquire hearing loss in the early years of their lives. Ototoxic medication, such as aminoglycoside antibiotics, may cause hearing loss by damaging inner ear hair cells. Other diseases such as meningitis, measles, encephalitis, chicken pox, influenza, and mumps may cause hearing loss as well. Additionally, head injuries, second hand smoke, and exposure to loud noise may permanently damage hearing in children.

How to Detect Hearing Loss in Children

Most infants are screened for hearing loss in the first few weeks of their lives. If hearing loss develops later, parents may recognize a delay in certain developmental stages in childhood.  You may find a guide provided by ASHA on developmental benchmarks here.

Detecting hearing loss early on and seeking treatment as soon as possible will benefit the child’s language, social, behavioral, and academic development as they grow.
