OBJECTIVE:To analyze the relationship between joint of heat and noise, and metabolic syndrome in a steel rolling factory workers.METHODS:A total of 590 steel workers were selected as subjects by cluster sampling method from workers of a steel factory. They were investigated by face to face way with the unified questionnaire which contents included personal information, occupational history, personal history, habits and other factors. Furthermore, height, weight, waist circumference and blood pressure were measured. Referring to the 2005 International Diabetes Federation (IDF) issued by the metabolic syndrome (MS) worldwide uniform definition combines waist diagnosis MS. A database was built by Epidata 3.0 software, and data was analyzed by SPSS 17.0.RESULTS:571 steel workers were from 22 to 60 years, mean age (41.2 -7.9) years old. The prevalence of metabolic syndrome in steel workers was 17.9%. The prevalence of metabolic syndrome of those who exposed to high temperature was 18.8%, higher than that of those who did not expose to high temperature (5.3%), there was a statistically significant difference (P < 0.05). The prevalence of metabolic syndrome of those who exposed to noise was 20.6%, higher than that of those who did not exposed to noise (14.0%) (P < 0.05). After adjusting for the effects of confounding factors, the prevalence of MS those who exposed to high temperatures and noise is 1.118 times as high as that of those who did not exposed to high temperatures and noise.CONCLUSIONS:The combined effects of heat and noise is related to the increasing prevalence of MS of steel workers.

Objective To develop pneumoconiosis patient's self-management scale and evaluate its reliability and validity.Methods The basic framework of the scale items was built through literature review and semi-structured interview procedure,then the items pool of the scale was revised by 60 experts and were selected to evaluate entries using Delphi method.And scale items were screened according to average,full marks ratio and coefficient of variation,in the end the reliability and validity of scale was evaluated.Results The positive coefficient of experts was 91.6%,and the mean of the expert authority score was0.81.The scale which included 44 items was made up of 7dimensionality after screening,symptom management(6),knowledge management(3),unhealthy habits management(3),compliance management(6),daily life management(10),emotion management(5),and self-efficacy(11).The whole scale's Cronbach a was0.945,the split-half reliability was 0.901.correlation coefficient was between 0.265 and 0.916(P 0.05).Conclusions The self-management scale of patients with pneumoconiosis has good reliability,validity and can be applied in practice.

目的 探讨倒班与高温作业工人生命质量的关系,为建立合理的倒班制度提供理论依据.方法 采用整群抽样的方法选择2013年3月-6月某钢厂参加职业健康检查的782名工人进行面对面问卷调查,问卷包括一般情况及SF-36生命质量调查量表两部分.一般情况包括性别、出生日期、身高、体质量、血压、婚姻状况、文化程度等;SF-36量表包括生理机能(PF)、生理职能(RP)、躯体疼痛(BP)、总体健康感(GH)、生命活力(VT)、社会功能(SF)、情感职能(RE)和精神健康(MH)8个维度,概括成生理健康(PCS)和心理健康(MCS)2个领域方面.采用EpiData 3.1软件建立数据库,用SPSS 13.0统计软件进行统计分析.结果 高温组PF、RP、GH、VT、SF和RE 6个维度的得分均低于非高温组,差异有统计学意义(P＜0.05).调整年龄、性别、体质量指数(BMI)、血压、工龄、婚姻状况、文化程度、家庭收入、吸烟、饮酒、体育锻炼、噪声、粉尘、CO等因素后,倒班对高温作业工人的生命质量的RP、GH、SF、RE、MH等维度及PCS、MCS、总评分有影响(P＜0.05).结论 倒班与高温作业工人的生命质量有关.

[Objective] To analyze the awareness and determinants of occupational health service(OHS) in steelworkers so as to provide scientific evidence for establishing OHS training models according to the characteristics of steel workers. [Methods]A total of 981 steelworkers were selected by cluster sampling method during March-June of 2011, and they were interviewed faceto-face via questionnaires to collect general information, awareness and demand of OHS. [Results] The awareness rate of occupational disease, OHS, and Law on Prevention and Control of Occupation Diseases in the 981 steelworkers were 82.2%, 52.1%, and 50.4% respectively. The results of multivariate analysis showed the type of work was a determinant of OHS awareness. More than 90% of the interviewed steelworkers presented demand for emergency facilities, regular physical examinations, and safety operation trainings. [Conclusion] The awareness rate of OHS is low in the steelworkers; however, there is a high demand for OHS. The awareness of OHS in the steelworkers is associated with type of work, and therefore, the employers should carry out flexible OHS trainings according to the characteristics of various types of work.
