Abstract
Background -Occupational Injury (work related injury) is among major public health
problems that accounts 1.5% of public health burden in terms of DALLY and an
economic loss of 5-10% GNP globally.Preventing or reducing work-related injury
among flour factory workers are one of the key issues in improving workers health and
safety in manufacturing industry. This issue is relevant particularly in developing
countries including Ethiopia.
Objective: The aim of this study is to assess magnitude and associated factors of
occupational injury among production workers in large scale flour factories in Asella
during the last 12 months.
Method: : Institution based Cross-sectional study design was conducted from March,17-
April 4 2015 among 412 study subjects were selected using simple random sampling
method taking payroll as a sampling frame.
Data collection was done by using interviewer administered questionnaire, observation
and record review by the Principal Investigator. The collected data were manually
checked for completeness and entered in to EP Info for data cleaning and finally
exported to SPSS for further analyses. Descriptive statistics and logistic regression
analyses methods were employed to determine factors that may have significant
association to the dependent variable. Variables that are identified as having p-value less
than 0.25 on bivariate analyses were considered as a candidate to be evaluated on
multivariable model, and then a variable with p-value less than 0.05 on final model were
considered as having significant association.
Result: The overall occupational injury prevalence rate was 24%. , exposure to excessive
heat at work was found to have positive association with accidental injury at AOR =
2.570, P value< 0.05, 95% CI (1.12-5.91), Accordingly, those employees who were
carrying heavy weight compared to their counterparts are at high risk of accidental injury
at AOR 1.432, p value 0.05 , (95% CI) (1.001-2.048),workers who have got regular
health and safety supervision are more likely not to encounter injury at. AOR = 3.052, p
value 0.002 , 95% CI (1.507-6.181), utilization of personal protective devices in which
those who are using the device are at lower risk of encountering accidental injury at and
AOR 0.39, p-value 0.001 ,(95% CI) (0.23-0.66). One more covariate identified as
significant was status of chewing chat. Employees who are chewing chat are six times at
higher risk of acquiring accidental injury compared to those who are not chewing chat at
p-value < 0.05.
Conclusion - result show that work-related injury prevalence is high over the last one year.
The factors significantly associated with incident of injury were utilization of personal
protective device, handling of heavy object, excessive heat at work, Regular health and safety
supervision &chewing chat
