Untreated hearing loss increases the risk of dementia and depression

One study found that elderly patients with hearing loss, if not treated, had an increased risk of dementia, depression, falls, and other diseases.

A study in the United States found that untreated elderly hearing loss patients had a 50% higher risk of dementia and a 40% higher risk of depression than a normal hearing person. Almost 30% higher.

The study also found that among participants, untreated hearing loss patients had a 30% increased risk of stroke and a 36% increased risk of acute myocardial infarction compared with those with normal hearing.

The study found that during the decade, compared with people with normal hearing, in every 100 untreated hearing loss patients, the diagnosis of dementia was 3.2 more, 3.6 cases of falls, and 6.9 cases of depression. example.

The absolute risk of comorbidities associated with untreated hearing loss increases with prolonged follow-up.

Data behind the research

Researchers at the Bloomberg School of Public Health at Hopkins University in the United States analyzed their information in the OptumLabs Data Warehouse. The OptumLabs database is a large data set that includes 150,000 administrative claims for people aged 50 or older who participated in a large private health program in the United States and a federal health insurance priority plan from 1999 to 2016. The researchers observed the participants for 2, 5, and 10 years.

Earlier, several studies found a link between hearing loss and dementia and depression.

The study, titled “Incident Hearing Loss and Comorbidity A Longitudinal Administrative Claims Study,” was published in JAMA in 2018 in the Journal of Otolaryngology – Head and Neck Surgery.

(8.27-8.31) Increased risk of hearing loss in smokers

A Japanese study found that smoking is associated with an increased risk of hearing loss.

As we all know, smoking is harmful to health. Now, one study found that smokers are at greater risk of hearing loss.

A study conducted by 50,195 employees in Japan found that after adjusting for other factors (including occupational noise), smokers were 1.6 times more likely to suffer from high-frequency hearing loss than non-smokers (60%), suffering from low-frequency hearing loss. The risk increased by 1.2 times.

Studies have shown that the risk of high frequency and low frequency hearing loss increases with the number of daily cigarettes. At the same time, the study also showed that the risk of hearing loss after smoking cessation will be reduced, even for people who have stopped smoking for less than 5 years.

Smoking is an independent risk factor

The first author of the study, Dr. Huanhuan Hu of the National Center for Global Health and Medical Affairs in Japan, said: “Because of the large sample size, long follow-up, and objective assessment of hearing loss, our study confirmed that smoking is independent of hearing loss. Risk factors provide strong evidence.”

About research

The study included 50,195 Japanese employees aged 20-64 who did not suffer from hearing loss at the start of the study. Follow-up of participants was followed for up to 8 years. The researchers analyzed the participants’ annual health check data, including audio tests conducted by technicians and questionnaires on healthy lifestyles. The researchers examined the effects of each participant’s smoking status (now smoking, previous smoking and never smoking), the number of daily cigarettes, and the duration of smoking cessation on the extent of hearing loss.

During the follow-up period of the study, 3,532 people experienced high frequency hearing loss and 1,575 people experienced low frequency hearing loss.

The study titled “Smoking, Smoking Cessation, and the Risk of Hearing Loss: Japan Epidemiology Collaboration on Occupational Health Study”, published in “Nicotine & Tobacco” Research (Nicotine and Tobacco Research) (Oxford University Press) Journal.
