We assessed Knowledge Attitude and Practice (KAP) regarding occupational noise exposure, Noise-induced hearing loss, audiometry and use of hearing protection devices among iron and steel factory workers exposed to high noise level. A modified, validated, structured questionnaire was used to collect information from 253 male workers randomly selected from the four factories. The sum scores for each domain of KAP were computed. Scores above 75% were defined as good knowledge and positive attitude. For practice, scores of >50% were defined as good. Independent samples -test and Chi-squared test were used to analyze association between KAP and continuous/categorical variables respectively. Majority of workers displayed poor knowledge and poor practice (94%), but 76% displayed a positive attitude. Most of the workers (86%) had never been provided with hearing protection devices. The mean scores for attitude and practice differed significantly between the four factories (one-way ANOVA, < 0.001). Implementation of hearing conservation program with provision of hearing protection devices are suggested.
我们评估了高噪声水平钢铁厂工人对职业噪声暴露、噪声性听力损失、听力测定及听力保护装置使用的知识、态度和行为（KAP）。采用一份经过修改、验证的结构化问卷，从四个工厂随机抽取的253名男性工人中收集信息。计算KAP各领域的总分。得分高于75%被定义为知识良好和态度积极。对于行为，得分>50%被定义为良好。分别使用独立样本t检验和卡方检验分析KAP与连续/分类变量之间的关联。大多数工人知识和行为较差（94%），但76%态度积极。大多数工人（86%）从未获得过听力保护装置。四个工厂之间态度和行为的平均得分差异显著（单因素方差分析，P<0.001）。建议实施听力保护计划并提供听力保护装置。
