“…This result is consistent with the findings of other similar studies (Alberti 1998;Ferrite and Santana 2005;Koh and Jeyaratnam 1998; Model 1: Hearing threshold differences ≥30 dB between 4,000 Hz and 1,000 Hz in both ears Mizoue and Miyamoto 2003;Palmer and Griffin 2002;Pouryaghoub et al 2007;Rabinowitz and Thomas 2005;Uimonen et al 1998). A possible explanation for the underlying pathogenic mechanism may be the well-known vascular changes and the consequent cochlear hypoxia related to both smoking and long-term intense noise exposure (Chen 2002;Hawkins 1971;Starck et al 1999).…”

“…Despite widespread implementation of hearing conservation programs, noise is still the most frequent occupational hazard in workplaces (Ferrite and Santana 2005;Koh and Jeyaratnam 1998;Mizoue and Miyamoto 2003;Rabinowitz and Thomas 2005;Uimonen et al 1998). It is estimated that about 600 million workers are exposed to workplace noise worldwide (Alberti 1998;Ferrite and Santana 2005).…”

Background Noise-induced hearing loss (NIHL) is one of the oldest occupational diseases. Evidence has accumulated in recent years on the adverse effects of smoking on hearing among the working population, but the absence of such an association has also been reported. Both cigarette smoking and noise exposure have a common pathway to produce hearing loss. Materials and MethodsWe surveyed the effect of smoking on NIHL in 478 workers in a large automobile manufacturing company who were exposed to unauthorized levels of noise. All required data were obtained using direct interviews and questionnaires. The results of the chi-square test and the regression models are expressed as odds ratios (OR) with 95% confidence intervals (95% CI). Results The frequency of hearing loss in smokers was higher than in non-smokers based on model 1 (hearing threshold differences ≥30 dB between 4,000 Hz and 1,000 Hz in both ears; OR 23, 95% CI: 11.90-44.42; p<0.001) and model 2 (hearing threshold level of >25 dB at 4,000 Hz in the better ear; OR 6.94, 95% CI: 4.53-10.64; p<0.001). These results were confirmed by the logistic regression statistical method. Conclusion It can be concluded that smoking may accelerate noise-induced hearing loss, and smoking cessation may be useful for prevention of NIHL, but more studies are required to confirm this.

“…In France, 107 injuries with sick leave occurred per 1,000 workers in 1999 (CNAMTS 2001). Several studies have shown the danger of construction jobs (Koh and Jeyaratnam 1998) and the high death rate (Lipscomb et al 2000;Jackson and Loomis 2002). Apart from environmental factors, other factors contribute, especially age (Jackson and Loomis 2002) or alcohol consumption (Lipscomb et al 2000).…”

The causes of injuries were related to jobs. Prevention through working conditions could be made against the revealed risks. The risks for each worker depended on age, body mass index, hearing disorders, sleep disorders, and sporting activities. The occupational physician could inform the workers of these risks and encourage them to practise sporting activities and reduce their hearing disorders and sleep disorders.

“…These issues, together with changing global work trends-an ageing workforce; the growth of small businesses; self-employment; part-time work; outsourcing; and migrant workers-challenge the validity of the traditional SME approach [Okubo, 1997;Koh and Jeyaratnam, 1998;Gunningham and Johnstone, 1999;Nicholson, 2002]. As multinational companies increasingly set up manufacturing bases in countries throughout Asia, a regional co-operative approach could be considered in developing common SME guidelines.…”
