Economic costs and Predictors of occupation-related Injuries in Ethiopian sugar industries from the Employer's perspective: top-down approach and friction method.

BACKGROUND: For many industrial workers, occupational injuries are a common health and safety concern. However, sufficient information on the economic costs and predictors of occupation-related injuries from the perspective of employers is lacking in developing countries, including Ethiopia. The objective of this study was to close this gap by quantifying the economic costs and predictors of occupation-related injuries in Ethiopian manufacturing industries from the employer's perspective. METHODS: A cross-sectional study was employed to estimate the employer-side economic cost of occupation-related injuries from December 2021 to March 2022. This study used a top-down approach to compute direct costs, while the friction method was used for indirect cost estimation. Injury data were obtained from the Bureau of Labour and Social Affairs and the industries, while cost data were from workers' compensation records. The insurance company's injury compensation record was triangulated with industries' data. The study collected primary data via an interview-administered, semi-structured questionnaire from 1136 randomly selected injured cases. Statistical analysis was carried out with STATA version 14 software. The study employed a generalized linear model to identify predictors of total cost by considering the non-normal distribution of the total cost. Exponentiate coefficients with a 95% confidence interval were used to express the direction and strength of the association. RESULTS: The survey participation rate was 100%. From the perspective of the employers, the total cost of occupation-related injury was 22,587,635.32 Ethiopian birr (537,800.84 $).Indirect and direct costs accounted for 65.86 and 34.14% of the overall expenses, respectively. Long-term absence from work (exp (b) = 0.85), having a sleeping disorder (exp (b) = 0.90), co-morbidity (exp (b) = 0.85), and severity (type) of injury (exp (b) = 1.11) were predictors significantly associated with the total cost variability in the fully adjusted model. CONCLUSIONS: Employers' toll of occupation-related injuries has severe economic implications. The influential factors that elevated the total cost variation were: long-term absence from work, unsafe acts of the workers, having a sleeping disorder, co-morbidity, and severity (type) of injury. Therefore, the identified modifiable factors are the areas of intervention to reduce the cost of occupation-related injuries.

Bagasse dust exposure and chronic respiratory symptoms among workers in the Metehara and Wonji sugar factories in Ethiopia: a longitudinal study design.

BACKGROUND: Ethiopia's sugar factories are growing by creating job opportunities for thousands of workers with varying educational, professional and socioeconomic backgrounds. These sugar factories are a source of several hazards that severely harm the workers' health. In this context, there is inconclusive evidence on the level of bagasse dust exposure and chronic respiratory health symptoms. This study aimed to assess the degree of bagasse dust exposure and chronic respiratory health symptoms. METHODS: In this longitudinal study, five workstations were selected for dust sampling. A stratified random sampling technique was used to select 1043 participants. We measured the dust intensity using a calibrated handheld real-time dust monitor once a month for 5 months, totalling 50 dust samples. Chronic respiratory symptoms were assessed using the American Thoracic Society's respiratory symptoms questionnaire. RESULTS: A 1 hour time-weighted average of bagasse dust intensity in the boiler, power turbine and evaporation plant was 8.93 mg/m3, 8.88 mg/m3 and 8.68 mg/m3, respectively. This corresponded to an exposure level to bagasse dust of 85.52% (95% CI 83.2% to 87.6%). The level of chronic respiratory health symptoms was 60.6% (95% CI 59.2% to 61.9%). The most common respiratory symptoms were wheezing (96.8%), coughing (89.7%) and breathlessness (80.9%). The identified risk factors were lack of dust control technology (ß= 0.64, 95% CI 0.53 to 0.75), not practising wet spray (ß = 0.27, 95% CI 0.21 to 0.41) and not wearing proper respiratory protection devices (ß = 0.12, 95% CI 0.30 to 0.56). CONCLUSIONS: Bagasse dust exposure and respiratory health abnormalities were worrying concerns. The absence of dust control technologies and no practice of wet spraying elevated the level of exposure. Not wearing proper respiratory protection gear increased the odds of having respiratory abnormalities. Hence, the use of mechanical solutions to stop dust emissions at their sources and the wearing of proper respiratory protection gear are highly advised.

Factors contributing to occupational injuries among workers in the construction, manufacturing, and mining industries in Africa: a systematic review and meta-analysis.

Personal injuries, illnesses, or deaths resulting from occupational accidents pose critical public health issues with severe social and economic implications. Studies on risk factors for occupational injuries in Africa have been indecisive. This study aimed to identify factors influencing occupational injuries at the regional level and to generate estimates of the contribution of each. Of 603 studies accessed we included 20 that fulfilled the eligibility criteria. Workers with temporary employment and those not receiving safety training had higher odds of incurring occupational injuries [AOR = 2.13, 95%CI (1.06, 3.21) and AOR = 1.98, 95%CI (1.21, 2.76), respectively]. Temporary workers often do not benefit from occupational health and safety services to avoid accidents and injuries at work. Use of proper personal protective equipment reduced the odds of sustaining an injury [AOR = 0.60, 95%CI (0.32, 0.88)]. We suggest focusing interventions on the identified modifiable factors to lessen the burden of work-related injuries.
