Respiratory symptoms related to flour dust exposure are significantly high among small and medium scale flour mill workers in Ethiopia: a comparative cross-sectional survey

BACKGROUND@#International Labour Organization (ILO) report indicates more than 2.4 million workers die from work-related diseases and accidents each year. Work-related respiratory ailments related to airborne particulate matter such as flour dust are responsible for about 386,000 deaths and 6.6 million illness-adjusted life years. Even though exposure to flour dust together with the extreme expansions of flour mill sectors is a priority health concern, extent of the problem is little investigated in Ethiopia. The aim of this study was to evaluate the magnitude and risk factors of work-related respiratory symptoms among flour mill workers in Bahir Dar City, Ethiopia.@*METHODS@#This study employed a comparative cross-sectional survey of 560 samples (280 exposed group from flour mill workers and 280 unexposed group from office workers) with a stratified random sampling technique. The study was conducted from March to April 2019 in Bahir Dar City, Northwest Ethiopia. We used the British Medical Research Council (BMRC) questionnaire to assess work-related respiratory symptoms. The questionnaire was pretested and interview administered to collect data. Binary logistic regression analysis was fitted to evaluate significant factors of respiratory symptoms at a < 0.05 p value. Adjusted odds ratio (AOR) with a confidence interval (CI) of 95% was calculated to determine a strength of association.@*RESULTS@#All the sampled participants had fully responded to the interview. The median age of exposed and unexposed groups was 28.5 interquartile range (IQR, 20) and 31 (IQR, 15) years, respectively. The prevalence of work-related respiratory symptoms among flour mill workers was substantially higher than that of among controls, 63.9% and 20.7%, respectively (Χ@*CONCLUSION@#Respiratory symptoms emanating from exposure to various flour dusts were significantly higher among flour mill workers than among the control group. Therefore, we recommend the need to effectively implement health and safety programs that account for the reduction of dust at a source, use of engineering controls (e.g., provision of adequate ventilation systems), use of administrative measures (e.g., training program and health surveillance) and provision of a suitable personal protective equipment (PPE). Furthermore, it is vital to integrate workplace health and safety programs to the wider public health policies and strategies to effectively mitigate the burden of work-related respiratory conditions. We also encourage future studies to evaluate concentration of flour dusts combined with physical examinations to establish plausible associations of respiratory symptoms with dusts of flour mill-related origin.

Violence at work: determinants & prevalence among health care workers, northwest Ethiopia: an institutional based cross sectional study

BACKGROUND: Workplace violence is the intentional use of power, threatened or actual, against another person or against a group, in work-related circumstances, that either results in or has a high degree of likelihood of resulting in injury, death, psychological harm, mal development, or deprivation. The aim of this study is to assess magnitude and predictors of workplace violence among healthcare workers in health facilities of Gondar city. METHODS: Institutional based cross sectional study design was employed to conduct this study. The study conducted in Gondar town from February 21 to march 21, 2016. Five hundred fifty three health care workers selected from health facilities of Gondar City administration. A stratified sampling technique was used for selecting the study subjects through simple random sampling. Data was collected by structured self administered questionnaire which is adapted from ILO/ICN/WHO/PSI after it is pretested & prepared in Amharic. The data was coded and entered in to EPI info version 7 and exported to SPSS version 20 software for analysis. The degree of association for variables was assessed using odds ratios with 95% confidence interval and p-value ≤0.05. RESULTS: The prevalence of workplace violence was found to be 58.2% with [95% confidence interval (CI): (53.7, 62.3)] in which verbal abuse 282(53.1%) followed by physical attack 117(22.0%) and 38(7.2%) sexual harassment. Working at emergency departments [AOR = 3.99,95% CI:(1.49,10.73)], working at shifts [AOR = 1.98,95%, CI: (1.28,3.03)],short experiences [AOR = 3.09,95% CI: (1.20,7.98)], being nurse or midwife [AOR = 4.06, 95% CI: (1.20,13.74)] were positively associated with workplace violence. The main sources of violence are visitors/patient relatives followed by colleagues and patients. CONCLUSION: workplace violence is major public health problem across health facilities and the Ministry of Health should incorporate interventions in its different health sector development & management safety initiative.

Self-report occupational-related contact dermatitis: prevalence and risk factors among healthcare workers in Gondar town, Northwest Ethiopia, 2018-a cross-sectional study

BACKGROUND@#Occupational skin diseases are the second most common occupational diseases and are responsible for an estimated 25% of all lost work days. Occupational contact dermatitis (OCD) comprises 70-90% of all occupational skin diseases. In Ethiopia, information about the prevalence and factors which determine developments of contact dermatitis is not recognized. The objective of this study was to investigate prevalence and factors influencing the occurrences of occupational-related contact dermatitis among healthcare workers in Gondar town, Northwest Ethiopia.@*METHODS@#We employed a healthcare-based cross-sectional study from March to April 2018. A stratified sampling method followed by simple random sampling method was used to select 422 participants. The standardized Nordic Occupational Skin Questionnaire was pretested and interviewer-administered for data collection. We used SPSS version 20 to conduct a binary logistic regression analysis. We set ≤ 0.05 p value to ascertain significance and 95% CI with odds ratios to evaluate the strength of associations.@*RESULTS@#Response rate was 100%. The majority, 52.4% (N = 221), were males. The mean age was 22.6 (SD ± 6.3) years. The overall prevalence of self-report occupational contact dermatitis in the previous 12 months was 31.5% (N = 133) [95% CI (27, 36.2)]. The highest symptoms indicated was redness, 28.5% (n = 38), followed by burning, 17.3% (n = 23). The hand is the most commonly affected body sites, 22% (N = 93). Hand washing frequency [AOR 1.80, 95% CI (1.10, 3.20)], pairs of hand gloves used per day [AOR 3.22, 95% CI (2.05, 5.87)], personal history of allergy [AOR 2.37, 95% CI (1.32, 4.61)], and lack of health and safety training [AOR 2.12, 95% CI (1.12, 2.25)] were factors considerably associated with contact dermatitis.@*CONCLUSIONS@#The prevalence of occupational-induced contact dermatitis is common among healthcare workers in Ethiopia. Therefore, our finding indicates that intervention aiming at workers' health and safety training demands urgent public health responses to tackle the ailment. The result also demonstrates that healthcare workers should be aware of when and how hands should be washed. The number of pairs of gloves used per day should also be taken into consideration while devising prevention strategies.

Factors associated with risky driving behaviors for road traffic crashes among professional car drivers in Bahirdar city, northwest Ethiopia, 2016: a cross-sectional study

BACKGROUND@#Road traffic injury is one of the persistent public health challenges in most regions of the world, representing substantial human and economic losses. Annually, about 1.25 million lives are lost, whereas 50 million suffer from road traffic injuries globally. It has been shown that over 60% of the reasons for traffic injuries are a risky driving behavior (RDB). Despite the problem's pervasiveness, there is a paucity of information about level and factors influencing RDB among professional car drivers in Bahirdar city, northwest Ethiopia.@*METHODS@#An institution-based cross-sectional study was conducted from February to March 2016. A systematic random sampling technique was used to select 376 participants. A self-administered driver behavior questionnaire (DBQ) was used for data collection. We performed a binary logistic regression analysis to investigate the associations of variables. Potential confounders were controlled using a multivariable logistic regression model. We ascertained the significance at < 0.05 p value and evaluated strength of associations using crude odds ratios (COR) and adjusted odds ratios (AOR) with 95% confidence intervals (CI).@*RESULTS@#A total of 361 drivers participated (response rate, 96%). The mean age was 34 (standard deviations ± 7.97) years. The majority, 98.9% (N = 357), were males. The level of risky driving behavior and road traffic crashes were 79.4% (95% CI 75.92, 83.97) and 16.3% (95% CI 15.91, 24.84), respectively. Average monthly salary [AOR 2.04; 95% CI (1.23, 2.74)], driving experience [AOR 2.72; 95% CI (1.07, 6.89)], distance driven per year [AOR 2.06; 95% CI (1.13, 4.10)], and previous history of involvement in traffic crashes [AOR 2.30; 95% CI (1.15, 7.35)] were significantly associated with risky driving behavior.@*CONCLUSIONS@#The study shows that risky driving behavior is common among professional car drivers in the study setting. Therefore, it is strongly advisable for policy makers and other stake holders to devise strategies that consider working conditions, like monthly salary and driving experiences. The study also suggests that it is often advisable to reduce the distance driven per year and learn from implications of previous history of involvement in traffic crashes.

Sick at work: prevalence and determinants among healthcare workers, western Ethiopia: an institution based cross-sectional study

BACKGROUND: Going to work despite feeling sick also known as sickness presenteeism is one of the emerging global occupational health challenges. Sickness presenteeism negatively affects both health of work forces and productivity of organizations in general. However, there is insufficient research exploring this situation in majority of the Sub-Saharan African countries, including Ethiopia. Thus this study intended to investigate the prevalence and determinant factors of sickness presenteeism among health care workers, Western Ethiopia. METHODS: This study used an institution based cross-sectional quantitative study design. The study period was from February to March, 2017. We employed simple random sampling method to select 360 study samples. Data collection was performed by pre-tested structured and self- administered questionnaire. We used SPSS version 20 to carry out binary logistic regression analysis. Odds ratio with 95% confidence intervals was calculated and significance of associations was determined at p-value < 0.05. RESULTS: A total of 344 respondents fully completed the survey questionnaire. Mean age with standard deviation was 30.28 ± 6.181. Prevalence of sickness Presenteeism was 52.6% [95%CI: (47.4, 57.8)] in the past 12 months. Educational status [AOR:2.1, 95%CI: (1.17,3.90)], financial problem [AOR:1.9,95%CI:(1.07,3.46)], sickness absenteeism [AOR:2.7,95% CI:(1.50,5.02)], lack of staff replacement [AOR:2.7,95%CI:(1.50,5.02)], absence of occupational health services [AOR:3.0,95%CI:(1.34,6.70)], and pressure from supervisor [AOR:1.8,95% CI:(1.01,3.31)] were significant predictors of the dependent variable. CONCLUSION: Relatively higher proportions of workers indicated sickness presenteeism as compared to other studies. Risk factors like educational status, personal financial problem, sickness absenteeism, lack of staff replacement, absence of occupational health services, and pressure from supervisors considerably increased the likely occurrence of employees’ sick attendance. It is advisable for health care managers to hire adequate health care staffs, to implement basic occupational health services and to design strategies which reduce pressure from supervisors.
