Epidemiological Study On Risk Factors Of Occupational Injuries Occurred Between 2007-2009 In Hefei

Objective: study 1:Through a retrospectively descriptive study on occupational injuries occurred between 2007-2009 in Hefei, to study the population, time and space distribution feature, suggest the focus of prevention and risk factors of occupational injury. Study 2:Studying distribution feature and factors of occupational injury, and conducting epidemiological analysis on those factors to provide evidence of occupational injury prevention for enterprises, to point out the effective measures to safeguard production safety, to strengthen Disability prevention work and lighten the burden on society, to encourage relevant departments to adopt appropriate measures to reduce the damage.Materials and methods:Study 11. Participants: people having experienced occupational injury are registered in civil administration injury registration system between 2007 and 2009.2. Study content: the content include: the participants'working places, names ,gender, age, working type,where and when the occupational injury and how the occupational injury happened.3. Statistical methods: we use descriptive method to depict the rate of occupational injuries,rate of injury per thousand,rate of moderate injury per thousand and rate of severe injury per thousand. Circular statistic was employed to calculate the seasonal data and test the significance.Study 21. After a close scrutiny of occupational injuries registration data kept in labour bureau, we selected Ma Anshan steel company,changyuan Hydraulic group and GITI tire corporation where occupational injuries concentrated. a case-control study was employed upon which cases was defined as people experienced occupational injuries and controls were selected from workers who have not suffered occupational injuries based on 1:1 frequency matching.2. Study content: 1) subjects'age,gender,height,weight,working age etc were collected as dimorphic. 2) The information about occupational injury such as where can when these injuries happened. 3) General factor affecting occupational injuries, such as history of alcohol and tobacco use, personal characteristics, etc. 4) the states of occupation injury: occupational stress inventory - revised edition,OSI-R was used to evaluate the participant's occupational intense.3. Statistical method: using Epidata 3.0 construct database. SPSS 11.5 was used to analyze data. Chi-square was used to compare the difference between case and control group, risk factor was determined by logistic regression model.Results: study 1:the thousands death rate of the company's occupational injury was decreasing every year. With respect to the time distribution of occupational injury, Slight injuries tend to be occurred in July, but the serious injuries and death are no distinct time distribution. In last part of a month, it is more possible to occur occupational injury. Regarding gender, the incidence rate of occupational injury is higher among males than females; the rate is 3:1. the slight injures are more likely to happen in 26-28 age group and 38-40 age group, serious injuries are more likely to happen in 36-38 age group and 40-42 age group. The danger of happening injuries among jobs are listed as follows: Operators, staff, the pilot, Pliers worker, wield worker, maintenance, waiter, molding, Lathe worker, cooks, merchandisers and electrician, cleaner and security. The types of occupational injury are listed orderly as follows: Body blow, mechanical damage, electric shock, drowning. Parts of injured body are listed orderly as follows: Amputation and hands, and lower limbs and other, jaws, brain and chest- abdomen department. The most happened seriously injured part is chest- abdomen department, the most happened death are chest- abdomen department and brain. Study 2:The results show that the occupational injury is correlated to work age, income, health status and martial status. The people who have longer worker age, higher income, healthier and more stable martial status are less likely experienced occupational injury. the differences between case group and control group about Role overload, role insufficiency, role ambiguity, role boundary, responsibility, physical environment, personal strain questionnaire, vocational strain, psychological strain, interpersonal strain, physical strain, personal resources questionnaire, recreation, self-care, social support, rational/cognitive are statistically significant. A higher Personal resource is a protective factor of occupational injuries. Working with individual protective equipment is also a protective factor of occupational injuriesConclusion(1) We should protect people who have shorter work age, and strength the publication about producing safety during time when the occupational injuries are easily happened. Some training should be launched to those work position which are easily affected by occupational injuries. Some protective equipment should also be developed to protect some body parts that are easily injured. (2) Business training and health education, Psychological needs, should be strengthened in employment, when we carry out intervention, we should focus on high risk population...
