Hearing loss in migrant agricultural workers

Area of Science:

• Occupational Health
• Audiology
• Public Health

Background:

• Farmers exhibit high hearing loss rates, but migrant agricultural workers' hearing status is largely unknown.
• This study addresses the gap in understanding hearing loss prevalence and impact within this vulnerable population.

Purpose of the Study:

• To assess the prevalence and impact of hearing loss among migrant and seasonal agricultural workers.
• To identify risk factors associated with hearing loss in this demographic.

Main Methods:

• A cross-sectional survey involving 150 migrant and seasonal agricultural workers at health fairs.
• Bilingual questionnaires collected data on hearing loss risk factors and subjective difficulties.
• Pure tone audiometry and tympanometry were conducted using a mobile testing van.

Main Results:

• Over 50% of workers showed hearing loss, especially at higher frequencies.
• Hispanic males had a higher prevalence of high-frequency hearing loss compared to national data.
• Over 35% reported difficulty hearing/understanding speech; language barriers worsened impact. Age and abnormal tympanometry were risk factors. Noise/pesticide exposure was common, hearing protection rare.

Conclusions:

• Hearing loss is a significant, under-recognized issue among migrant workers.
• Further research and interventions are needed for prevention and treatment.
• Addressing occupational exposures and language barriers is crucial for this population.
