Age-related hearing loss and blood pressure

Area of Science:

• Audiology
• Cardiology
• Gerontology

Background:

• Cardiovascular disease (CVD) and hearing loss are prevalent in aging populations.
• Existing literature suggests a potential association between hearing impairment and CVD, though findings are sometimes contradictory.
• Interactions between noise-induced or age-related hearing loss and CVD have been explored.

Purpose of the Study:

• To investigate the correlation between blood pressure, hypertension, and auditory function in an elderly population.
• To examine potential differences in these associations based on age and sex.

Main Methods:

• Utilized data from an epidemiological study of elderly individuals in Gothenburg, Sweden.
• Analyzed correlations between systolic and diastolic blood pressure and hearing function across different age groups (70-85 years) and sexes.
• Focused on hearing loss in low and mid-frequencies.

Main Results:

• A probable correlation was observed between high systolic blood pressure and low/mid-frequency hearing loss in 79-year-old women.
• A tendency for a similar correlation was noted in 85-year-old women.
• High diastolic blood pressure was associated with low/mid-frequency hearing loss in 85-year-old women.
• No consistent associations were found in younger elderly women (70-75 years) or in men aged 70-85 years.

Conclusions:

• The study suggests a potential link between hypertension and hearing impairment, particularly in older women.
• The association appears specific to certain age groups and frequencies, indicating a complex relationship.
• Further research is warranted to elucidate the mechanisms underlying this connection.
