Objective To evaluate the intervention effects of a workplace health promotion (WHP) program in a smallscale chemical enterprise.
Methods A WHP intervention program tailored to the enterprise management mode including ameliorating working environment, training and education, and health services was implemented in a small chemical enterprise in 2010-2014. Respectively 202 employees before the intervention and 130 employees after the intervention were investigated. Levels of occupational health management of the enterprise, as well as changes in knowledge and lifestyle of the staff, were evaluated before and after the intervention.
Results A total of 195 (96.5%) valid questionnaires were collected before the intervention, while 130 (100.0%) valid questionnaires after the intervention were returned. After four years of intervention, the qualified rates of occupational hazard monitoring in workplace, staff occupational health examination, and job satisfaction all reached 100.0%, and no occupational disease or contraindication was reported in the four consecutive years. Moreover, 99.2% of the workers knew or knew well about the law and regulations on prevention and control of occupational diseases, 96.2% knew the concept of occupational diseases, 100.0% believed that occupational disease are preventable; sick leave rate in the past year was 6.2%, lower than 17.9% before the intervention (P<0.05). The proportions of workers reported exercise and having a light diet increased from 88.7% and 31.8% before the intervention to 96.2% and 69.2% after the intervention respectively (P<0.05); the proportion of workers favoring salty tastes decreased from 13.3% before the intervention to 3.8% after the intervention (P<0.05). As to the needs for such relevant services and health knowledge as chronic non-communicable disease prevention and balanced diet increased to 76.2% and 66.9% (P<0.05) from 65.6% and 54.9% before the intervention.
Conclusion WHP could improve the working conditions of the small chemical enterprise, change unhealthy lifestyles, control health risk factors, and reduce injuries and diseases.
