MAQUEDA BLASCO, Jerónimo et al. Systematic review and evidence on occupational noise exposure and extra-auditory effects of no cardiovascular nature. Med. segur. trab. [online]. 2010, vol.56, n.218, pp.49-71. ISSN 0465-546X.
Review aimed at ascertaining the level of evidence on non-auditory effects related with occupational exposure to noise concerning: biochemical, neuro- psychology effects, reproductive health and accidents at work through a systematic analysis of the scientific literature published between 1995 and 2008. The search for references was conducted using terms "Major Topic" and "MeSH" terms for MEDLINE and "Decriptors" for OSH update. We retrieved a total of 370 references, were included in the review all experimental studies, cohort studies and case control studies and those cross-sectional studies that had at least five of the nine criteria that the STROBE Statement provides for observational studies. Were selected for full text review a total of 35 studies: 14 experimental studies, 2 cohort studies, 6 case control studies, 12 cross-sectional studies and 1 validation study. The assignment of the level of evidence was performed according to SIGN criteria. The selection and review of articles was done by peer review, cases of disagreement between pairs was resolved by consensus. We found a high level of evidence (1+) about the influence of occupational noise exposure and the increased secretion of cortisol and norepinephrine, fatigue and decreased performance, cognitive function and memory, decreased quality of sleep, stress and irritability annoyance. A level of evidence 2++ was identify for occupational noise exposure and work accidents. We found no conclusive results in determine the relationship between occupational exposure to noise on reproductive health. There is diversity in the methods used for assessing occupational exposure to noise, using both quantitative measurement methods and qualitative methods of subjective perception. Our results are consistent with those previously reported by Smith AP et alt (1991) and Butler MP et al (1999).
