| Popis: | This study set out to determine the pattern and predictors of noise-induced hearing loss (NIHL) among small-scale and self-employed chili pepper grinders in Lagos, Southwest Nigeria. Audiological evaluation was conducted for all participants after noise level measurement. Of 136 studied, 85 (62.5%) were confirmed with slight-to-moderate NIHL. Mean age was 40.2 years, mean years spent as grinders was 9.3 years and mean hours spent daily at work was 13.3 hours. The mean age of those with NIHL was significantly higher than those without. Spending over 10 years in commercial grinding and working ≤12 hours daily were predictive of NIHL. Questionnaire-based screening using symptoms of NIHL was associated with a sensitivity of 44.7%, specificity of 62.7%, and positive predictive value of 66.7%. In conclusion, pepper grinding is associated with high/excessive noise levels and NIHL. Hearing conservation program incorporating engineering modification of locally fabricated grinders is warranted in this and similar populations in developing countries. |
