CANTLEY. Linda F.; GALUSHA, Deron; CULLEN, Mark R. et al. Association between ambient noise exposure, hearing acuity, and risk of acute occupational injury. [online]. Scandinavian Journal of Work, Environment & Health. 19.08.2014. 9 p. [Consulta 01.09.2014]. doi:10.5271/sjweh.3450.
Los resultados de este estudio indican que una exposición al ruido en el trabajo de tan sólo 85 dBA puede aumentar el riesgo de lesiones y que la discapacidad auditiva pueden estar asociados con un mayor riesgo de lesiones menores. Estos hallazgos sugieren que en los programas de prevención de lesiones en el trabajo podría ser necesario considerar la exposición al ruido como factor de riesgo a prevenir. Palabras clave: lesión laboral aguda; ruido ambiental; asociación; exposición; auditiva; agudeza auditiva; pérdida de la audición; ruido; exposición al ruido; salud en el trabajo; seguridad en el trabajo
Els resultats d'aquest estudi indiquen que una exposició al soroll en el treball de tan sols 85 dBA pot augmentar el risc de lesions i que la discapacitat auditiva poden estar associats amb un major risc de lesions menors. Aquestes troballes suggereixen que en els programes de prevenció de lesions en el treball podria ser necessari considerar l'exposició al soroll com a factor de risc a previndre. Paraules clau: lesió laboral aguda; soroll ambiental; associació; exposició; auditiva; agudesa auditiva; pèrdua de l'audició; soroll; exposició al soroll; salut en el treball; seguretat en el treball
Objective This study aimed to examine the associations between acute workplace injury risk, ambient noise exposure, and hearing acuity, adjusting for reported hearing protection use. Methods In a cohort of 9220 aluminum manufacturing workers studied over six years (33 300 person-years, 13 323 person-jobs), multivariate mixed effects models were used to estimate relative risk (RR) of all injuries as well as serious injuries by noise exposure category and hearing threshold level (HTL) adjusting for recognized and potential confounders. Results Compared to noise <82 dBA, higher exposure was associated with elevated risk in a monotonic and statistically significant exposure–response pattern for all injuries and serious injuries with higher risk estimates observed for serious injuries [82–84.99 dBA: RR 1.26, 95% confidence interval (95% CI) 0.96–1.64; 85–87.99 dBA: RR 1.39, 95% CI 1.05–1.85; ≥88 dBA: RR 2.29, 95% CI 1.52–3.47]. Hearing loss was associated with increased risk for all injuries, but was not a significant predictor of risk for the subset of more serious injuries. Compared to those without hearing loss, workers with HTL ≥25 dB had 21% increased all injury risk (RR 1.21, 95% CI 1.09–1.33) while those with HTL 10–24.99 dB had 6% increased risk (RR 1.06, 95% CI 1.00–1.13). Reported hearing protection type did not predict injury risk. Conclusion Noise exposure levels as low as 85 dBA may increase workplace injury risk. HTL was associated with increased risk for all, but not the subset of serious, injuries. Additional study is needed both to confirm the observed associations and to explore causal pathways.
