Noise-induced hearing loss among manufacturing factory workers in Kuching, Sarawak: Prevalence and associated risk factors.

INTRODUCTION: Noise-induced hearing loss (NIHL) is a common problem worldwide. Increased globalisation, as well as industrialisation, gives rise to an increase in the incidence of NIHL worldwide. Malaysia is not spared from this problem, either. The objectives were to determine the prevalence of NIHL and its associated factors among manufacturing factory workers. MATERIAL AND METHODS: A cross-sectional study was done in Kuching, Sarawak, involving 173 randomly selected respondents among manufacturing factory workers. Data collected were respondents' workplace monitoring data and their audiometry records obtained from the factory record, and the otoscopy examinations performed. In addition, respondents were required to fill up an interviewer-guided questionnaire. RESULTS: The prevalence of NIHL was high (49.7%). The factors which were found to have a significant association with NIHL in bivariate analysis were age (p < 0.05, 95% CI), male gender (p < 0.05; OR - 7.60; CI 3.34 -18.38), duration of employment (p <0.05), knowledge of noise level (p < 0.05; OR - 4.11; CI 1.10 - 15.28), working at polishing department (p < 0.05; OR - 4.23; CI 2.13 - 8.43), and smoking (p < 0.05; OR - 39.6; CI 16.5 - 94.8). Pack-years of smoking were also found to have a significant association with p < 0.05. However, only smoking was statistically significant in multivariate analysis, where the risk of developing NIHL was 27.55 (p < 0.005; CI 10.74 - 70.64) among smokers. CONCLUSION: The high prevalence of NIHL despite the existing Hearing Conservation Program (HCP) may indicate that there may be some elements in HCP that require close monitoring by the factory management, and the importance of smoking cessation among the workers exposed to noise at the workplace should be highlighted.

Workplace violence among nurses in a Penang hospital: Prevalence and risk factors.

INTRODUCTION: Workplace violence (WPV) has become a universal concern and is perceived as a serious safety and health threat, especially in healthcare settings. Very few studies have been done previously to determine the prevalence of WPV and associated risk factors among nurses in Malaysia. Among the health professionals, nurses spend most of their time with patients compared to other healthcare professionals. Several studies suggested that nurses had a higher risk of experiencing WPV. This study determined the prevalence and associated risk factors of WPV among nurses in a government hospital. MATERIALS AND METHODS: This cross-sectional study involved 410 randomly selected respondents among nurses in a government hospital in Penang, Malaysia. Data were gathered through a self-administered questionnaire consisting of a standardised questionnaire regarding WPV. RESULTS: The prevalence of reported WPV was 43.9%. The most common forms of WPV were verbal abuse (82.2%), followed by psychological violence (8.9%), physical violence (8.3%), and sexual violence (0.6%). The perpetrators were primarily among relatives of patients (51.7%), followed by patients (30%). Multiple logistic regression demonstrated that nurses working in the emergency department (ED) were six times more likely to experience WPV than in other departments (adjusted odds ratio (AOR) 6.139, 95% CI: 1.28 - 4.03). In addition, nurses in the age group of ≤30 years old were twice more likely to experience WPV (AOR 2.275, 95% CI: 3.4-11.08). CONCLUSION: This study indicates that the prevalence of WPV among nurses is high and most common among young nurses and those working in ED. Hence, hospital management should develop guidelines and comprehensive policies to prevent WPV. In addition, education and training, especially among young nurses and those working in the ED, are needed to increase their knowledge in the management and prevention of WPV and counselling sessions for nurses who have experienced WPV.
