Abstract:
Background: - Construction industry has been identified as one of the most hazardous industries
both in industrializing and non-industrialized countries. Work-related injuries in construction
sector is a major public health problem resulting in serious social and economic consequences
that could be prevented if appropriate measures are taken.
Objectives: - This study was employed to assess the prevalence of occupational injuries and
associated factors among construction workers at Koysha hydro-dam, Southwest Ethiopia, 2021.
Methods: - Construction site based cross-sectional study was employed on 409 randomly
selected study subjects. The data were collected by face-to-face interview. After checking for
completeness and consistency, entered into Epi-data manager and analyzed using SPSS version
25. Data exploration were computed and presented with tables and figures. Bivariate analysis
was run with each independent variable. Then variables with P-value < 0.20 were included in
multivariable logistic regression analysis. Hosmer-Lemeshow goodness of fit test was checked.
Finally, conclusion was made for that variables with P-value <0.05 in multivariable regression
analysis.
Results : - The annual prevalence of work-related injury among Koysha hydro-dam construction
workers were 37.7%. The mean age of participants was 31(SD+8.33) years. Twenty-nine
(18.8%) of injured respondents were hospitalized. Work related injury was significantly
associated with male sex [AOR=15.16;95%CI 6.60,34.82], formal education [AOR=0.5;95%CI
0.29,0.85], non-use of PPE [AOR=11.04;95%CI 5.04, 24.18] long working hours [AOR=2.15;
95% CI 1.24, 3.73], on-job training [AOR= 0.39; 95% CI 0.18, 0.83] and alcohol consumption
[AOR=5.44; 95% CI 2.99, 9.89].
Conclusion: - Alcohol consumption and being male increase the risk of work-related injury. On
job training, use of personal protective equipment, working <72 hours per week and education
were associated with low risk of work-related injury. On-job training, regular monitoring of
workers for substance abuse and encouraging workers to use PPE were crucial to reduce the
occupational injury and safeguard the workers
