[目的]了解钢铁工人有关代谢综合征(MS)的知识、态度和行为现状,为钢铁工人MS的干预提供理论依据。[方法]选取2015年3月某钢铁集团参加职业健康检查的男性工人938名对调查对象,采用面对面方式进行问卷调查,内容包括年龄、文化程度、婚姻状况、经济收入、工龄及工种,工人对MS相关的知识、态度和行为情况。使用Epi Data 3.1建数据库,SPSS 17.0统计软件包进行统计分析。[结果]938名钢铁工人中,对MS相关的各项知识的知晓率均低于60%,正确态度和生活习惯持有率均偏低;知识得分与态度及行为得分均呈正相关(P<0.01);电视和网络是钢铁工人最希望获取MS相关知识的两种途径。[结论]钢铁工人对MS相关知识的掌握程度整体偏低,态度和行为有待进一步提高,应当以文化程度较低的工人为重点对象,有针对性地开展MS健康教育,促进工人态度和行为的改变。 [Objective] To understand the knowledge, attitude and behavior status of steel workers about metabolic syndrome (MS) and provide the theoretical basis for the intervention of steel workers MS. [Methods] A total of 938 male workers who participated in the occupational health examination of an Iron & Steel Group in March 2015 were surveyed by means of face-to-face questionnaires. The questionnaires included age, educational level, marital status, economic income, length of service and type of work, MS-related knowledge, attitude and behavior. Use Epi Data 3.1 build database, SPSS 17.0 statistical package for statistical analysis. [Results] Among the 938 steelworkers, the awareness rate of MS related knowledge was less than 60%, and the correct attitudes and habits were low. Knowledge scores were positively correlated with attitude and behavior scores (P < 0.01); television and the Internet are two ways that steelmakers most want access to MS-related knowledge. [Conclusion] The overall mastery degree of MS related knowledge of steel workers is low and their attitudes and behaviors need to be further improved. The workers with lower education level should be the key target, and MS health education should be targeted to promote the attitudes and behaviors of workers change.
