Hearing Assessment of Farm Workers Exposed to Pesticides in Rio de Janeiro

Maria Isabel Kós conducted a study evaluating the peripheral auditory system of 70 individuals in Campos dos Goytacazes, Brazil. The dataset likely contains results from pure tone audiometry at eight frequencies, interviews on health and pesticide exposure, and a comparison between 35 farmers and 35 non-farmers. The study found the odds of hearing loss were 3.67 times higher among agricultural workers.

Use Cases

• Train a binary classification model to predict hearing loss risk based on occupation and exposure factors mentioned in the description.
• Analyze the correlation between pesticide exposure and hearing threshold shifts at specific frequencies (e.g., 250-8000 Hz).
• Conduct a comparative statistical analysis of hearing health between agricultural and non-agricultural worker cohorts.
• Build a risk assessment model for occupational hearing loss using variables like socioeconomic status and health history from the interviews.

Strengths

• Study design includes a control group of 35 non-farmers for comparative analysis.
• Audiometric data is collected at eight standardized frequencies (250 to 8000 Hz).
• Results include a specific Odds Ratio of 3.67 for hearing loss with a 95% confidence interval.

Limitations

• Row count and column-level documentation are unknown; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to a single study location in Rio de Janeiro.
• Last update date is unknown; freshness unverified.
