| Objectives To explore a kind of effective occupational health service (OHS)comprehensive intervention pattern for steel workers, we carried on comprehensiveintervention measure for steel workers’ and occupational health service staff’s knowledge,belief and behavior of OHS so as to provide a theoretical basis for improving OHS insteel workers.Methods981workers and44OHS staffs were selected as subjects by cluster samplingmethod from Steel rolling factory1and2field, and they were investigated by self-designquestionnaire which includes the basic characteristics such as age, gender and so on,OHS knowledge, belief and behaviors which involved in some OHS regulations ofenterprise, surveillance of the work environment and the use of protection equipment andfacilities, the setup of first aid facilities as well as their occupation health behavior. Afteranalyzing the baseline information on knowledge, belief and behavior of worker and staff,comprehensive intervention measures was formulated and executed in the beginning time,1week,2week,1month,2month and6month respectively. After the end ofintervention, they were investigated using the same questionnaire.so that the interventioneffect was evaluated.. The database was built by using Epidata3.0software. The statisticsanalysis was done by using SPSS13.0software. The score of OHS knowledge, belief, andbehaviors was expressed by mean with standard deviation. The difference of OHSknowledge, belief, and behaviors before and after the intervention was tested by t test fortwo groups. Qualitative data was expressed by rate or percentage and use chisquare-χ2test to analyze the rate of two groups. In final, the effect of comprehensive interventionwas evaluated by the comprehensive evaluation method.Results144OHS staff were investigated in the study, their average age was47.5±2.9years, age range from43to52years, the education level of high school ortechnological school or above was100%, male more than female, full-time staff (59.1%)was more than the part-time staff (40.9%).981workers were investigated. Theiraverage age was38.2±8.9years, age range from20to58years.81.8%female was morethan18.2%female,81.1%workers had above the education level of high school. Therewas no significant difference in in age, gender, educational level, marital status, and typeof work between two groups before and after the intervention(P>0.05).2In addition tooccupation disease, the knowledge changes of OHS staff after intervention was enhanced,especially the change rate in knowledge of the occupation disease prevention law, theconcept of OHS, OHS content before and after the intervention, had a statisticallysignificant differences (P<0.05), however, no significance difference in the knowledge ofworkplace harmful factors after intervention.100%workers know the concept ofoccupation disease whether before intervention or after intervention. After theintervention, those workers knowing3above entrance route of harmful factors to thebody were significantly increased (P<0.05). After the intervention, OHS staff’s awareness about occupational health services provided by the enterprise was increased inall the dimensions (P<0.05). The awareness of OHS function for staff had been improvedto above90%after the intervention, but for occupation health laws and regulations, hadno significance enhancement. For OHS staff’s behavior related to OHS, especially theknowledge of the workplace safety operation norms after intervention were increased to100%(P<0.05). The change of OHS behavior, except the workplace occupation hazardssurveillance and occupation disease hazard evaluation as well as the effect evaluation ofcontrol after the intervention had no statistical significance, the change rate of the otheritems was increased to100%(P<0.05).3The awareness of workers for OHS had beengenerally improved, especially the awareness rate of OHS content and knowledge wasimproved(P<0.05);57.4%of workers known more than5items about the rules andregulations of occupational health after the intervention. Those workers knew more thanthree main types of occupational health examination were from30.0%increased to78.1%after intervention. The change of d beliefs on OHS and the satisfaction at controlmeasures the enterprise taken had been increased (P<0.05). The demand of workers forOHS after the intervention had been increased to above90%. And the ambitionawareness obtaining OHS’ knowledge had been significant increased after theintervention (P<0.05). For worker’s OHS behavior, the "always use" frequency of7typesof personal protective equipment increased higher than that of before intervention. Inaddition to heat stress prevention, the "always use" frequency of6kinds of protectiveequipment for dust, poison, noise, vibration and ionizing radiation after the interventionwere higher than those before intervention. And the rate with workplace health and safetybehavior after intervention was increased more than that before intervention(P<0.05).4The knowledge, beliefs, behavior score and total score in OHS staff after interventionwere increased by8.70±2.61in knowledge,7.55±1.44in belief,9.02±1.22in behavior,and25.3±4.14in total respectively (P<0.05).5The knowledge, beliefs, behavior scoreand total score in steel workers after intervention were increased by8.01±4.94inknowledge,2.13±1.74in belief,4.13±3.88,in behavior, and14.4±7.61in totalrespectively (P<0.05).6Comprehensive evaluation index for OHS staff after intervention(98.4649), with comparison to77.6224before intervention increased20.8425. Forworkers comprehensive evaluation index was45.0886after the intervention, increased by12.5424compared with before intervention.Conclusions The comprehensive intervention can improve the knowledge, belief andbehavior of OHS staff and workers, and the comprehensive intervention for the workersand staff is effective. |
