Impact of Covid -19 incidence rate and government-initiated risk communication measures on individual's NPI practices.

BACKGROUND: Non-pharmaceutical interventions (NPI) are the most widely recognized public health measures recognized globally to prevent the spread of Covid-19. NPIs' effectiveness may depend on the type, combination of applied interventions, and the level of proper public compliance with the NPIs. The expected outcome of behavioural practices varies relative to the intervention duration. OBJECTIVES: This study aimed to assess the trend of community compliance to NPI with Covid-19 incidence and government-initiated interventions, and its variation by residence and sociodemographic characteristics of people. METHODS: A weekly non-participatory field survey on individuals' NPI practices was observed from the 41st epidemiological week of October 5th, 2020, to the 26th epidemiological week of July 4th, 2021, a total of 39 weeks. The survey covered all 14 regional and national capital cities in Ethiopia. Data collection for the three NPI behaviours (i.e., respiratory hygiene, hand hygiene, and physical distance) was managed weekly at eight public service locations using the Open Data Kit (ODK) tool. The Covid- 19 incidence data and public health measures information from August 3rd, 2020 to July 4th, 2021 were obtained from the Ethiopian Public Health Institute (EPHI). RESULTS: More than 180,000 individuals were observed for their NPI practice, with an average of 5,000 observations in a week. About 43% of the observations were made in Addis Ababa, 56% were male and 75% were middle age group (18-50 years). The overall level of NPI compliance was high at the beginning of the observation then peaked around the 13th- 15th epidemiological weeks then declined during the rest of the weeks. The peak NPI compliance periods followed the high Covid-19 death incidence and government-initiated intensive public health measures weeks. Respiratory hygiene had the highest compliance above 41% whereas hand hygiene was the lowest (4%). There was a significant difference between residents of the capital city and regional cities in their level of compliance with NPI. Females comply more than males, and individuals had increased NPI compliance at the bank service and workplaces compared to those in the transport services at P = 0.000. CONCLUSION: An increased level of compliance with NPI was observed following intensive government-initiated Covid-19 prevention measures and an increased Covid-19 death incidence. Therefore, the intensity of government-initiated risk communication and public advocacy programs should be strengthened, possibly for similar respiratory disease pandemics in the future.

Chronic Respiratory Symptoms and Associated Factors among Fruit and Vegetable Workers in Addis Ababa, Ethiopia: A Comparative Cross sectional Study.

Background: Fruit and vegetable market is an abundant source of bioaerosols. Exposure to organic and inorganic waste and long-term inhalation of bioaerosols during working hours leads to chronic respiratory symptoms. Hence, this study aimed to determine the prevalence of chronic respiratory symptoms and related factors among fruit and vegetable workers compared with the control group in Addis Ababa, Ethiopia. Methods and materials: A comparative cross-sectional study was conducted from 2020 to 2021. Data were entered in EpiData 3.1 and exported to Statistical Package for the Social Sciences (SPSS) version 25. Logistic regressions were computed to depict the data and related factors. The culture method was done to count and compare bacterial and fungal concentrations between fruit and vegetable workers and office workers. Results: In this study, the prevalence of chronic respiratory symptoms (PR = 2.87, 95% confidence interval [CI]: 1.772-4.66) was significantly higher among fruit and vegetable workers (46.7%) than controls (23.4%). Sex (adjusted odds ratio [AOR] = 2.11, 95% CI = 1.12-3.98), educational status (AOR = 1.34, 95% CI = 0.78-2.32), working hours per day (AOR = 3.91, 95% CI = 1.586-9.65), and working department (AOR = 3.20, 95% CI = 0.90-11.40) were associated with chronic respiratory symptoms. Bacterial and fungal concentrations were significantly higher in the air of the vegetable market (276 colony-forming unit) than the air in the workplace of controls (7 colony-forming unit). Conclusion: The fruit and vegetable market workers (greengrocers) had a higher prevalence of chronic respiratory symptoms relative to office workers. Respiratory protective devices should be given to deliver preventive measures.

Trends in non-pharmaceutical intervention (NPI) related community practice for the prevention of COVID-19 in Addis Ababa, Ethiopia.

BACKGROUND: The COVID-19 pandemic has affected Ethiopia since March 13, 2020, when the first case was detected in Addis Ababa. Since then, the incidence of cases has continued to increase day by day. As a result, the health sector has recommended universal preventive measures to be practiced by the public. However, studies on adherence to these preventive measures are limited. OBJECTIVE: To monitor the status of preventive practices of the population related to hand washing, physical distancing, and respiratory hygiene practices at selected sites within the city of Addis Ababa. METHODS: Weekly cross-sectional non-participatory observations were done during the period of April-June, 2020. Data was collected using the Open Data Kit (ODK) tool in ten public sites involving eight public facilities targeted for individual observations. Ten individuals were randomly observed at each facility over two days a week at peak hours of public services. WHO operational definitions of the preventive behaviors were adopted for this study. Observations were conducted anonymously at gates or entrances of public facilities and places. RESULTS: A total of 12,056 individual observations with 53% males and 82% in an estimated age range of 18-50 years age group were involved in this study. There was an increase in the practice of respiratory hygiene from 14% in week one to 77% in week 10, while those of hand hygiene and physical distancing changed little over the weeks from their baseline of 24% and 34%, respectively. Overall, respiratory hygiene demonstrated an increased rate of 6% per week, while hand hygiene and physical distancing had less than a 1% change per week, Females and the estimated age group of 18-50 years had practice changes in respiratory hygiene with no difference in hand hygiene and physical distancing practices. Respiratory hygiene took about six weeks to reach a level of 77% from its baseline of 24%, making an increment of about 9% per week. CONCLUSION: The public practice of respiratory hygiene improved threefold whereas hand hygiene and physical distancing revealed no change. Regularly sustained public mobilization and mass education are required to sustain the achievements gained in respiratory hygiene and further hand hygiene and physical distancing.

Temporary Hearing Loss and Associated Factors Among Ayka Addis Textile Factory Workers in Oromia Region, Ethiopia: A Cross-Sectional Study.

INTRODUCTION: The development of modern automated machines in industries has considerably decreased the physical burden of workers in addition to increasing the productivity of the industries resulting in noise pollution. Noise exposure above the limit value of 90 dB (A) is known to cause temporary hearing loss among exposed workers. MATERIALS AND METHODS: Institutional-based cross-sectional study design was employed for a total of 406 study participants using a simple random sampling technique from January 15 to April 30, 2019. The data collection methods were observational checklist and a self-administered questionnaire. The collected data were entered into EpiData software version 4.2 and exported to SPSS software version 21 for analysis. Bivariate and multivariable logistic analyses wwere used to identify the associated factors. Statistical significance was declared using a 95% confidence interval and a p-value of less than 0.05. RESULTS: A total of 388 study participants were included in the study with a response rate of 95.6%, of which 254 (65.5%) were females. The overall temporary hearing loss among the textile factory workers was found to be 49% with COR=1.53; 95% CI (1.15-2.03). The workers from the spinning department were 2.38 times more likely to develop temporary hearing loss after exiting from work than workers from the dyeing department (95% CI= (1.16-4.90). Similarly, workers from the knitting department were 3.67 times more likely to develop temporary hearing loss after exiting from work than workers from the dyeing department (95% CI=1.42-9.47). CONCLUSION: The present study demonstrated that the workforce in the spinning and knitting departments of the textile factory had a high prevalence of temporary hearing loss than the workers in dyeing and garment working sections. Therefore, the textile factory should provide hearing protection devices to the workers.

Prevalence of occupational injury and associated factors among workers in large-scale metal manufacturing factories in Addis Ababa, Ethiopia

Background: Worldwide work related injuries are becoming serious public health problems. However, very limited attempts have been made to assess the prevalence and factors associated with work-related injuries in Ethiopia. Objectives: The aim of this study was to assess the prevalence of occupational injury and associated factors among workers in large-scale metal manufacturing factories in Addis Ababa, Ethiopia. Methods: An institutional-based cross-sectional study was carried out among 588 metal workers in Addis Ababa, Ethiopia. Five metal factories were involved in the study. Data were collected using structured questionnaires, clinical data reviews and an observational checklist. Descriptive and multivariable analyses were done to describe the study population and identify risk factors associated with injury using an odds ratio with a 95%confidence interval (CI). Results: The prevalence of occupational injury among workers in the metal factories was 291 (49.9%) [95%CI: 45.8-53.9] per year. Among those injured respondents, 149 (51%) were not wearing personal protective equipment (PPE) at the time of injury. The use of PPE[adjusted odds ratio (AOR)=4.84; 95%CI: 2.93-8.01], attending primary school only [AOR=5.64; 95%CI: 3.05-10.43] and having 11 to 20 years' work experience [AOR=7.878; 95%CI: 2.60-23.90], were major predictors of work-related injury after adjusting for confounding factors. There were 18 recorded incidents resulting in major disabilities in one factory during the study period. Conclusions: The prevalence of occupational injury among metal workers was high. The use of PPE, attending primary school and those who had 11 to 20 years work experience were major predictors of work related injury. There is a need of provide an adequate supply of PPE for all metal workers and to ensure that they use it

Determinants of Chronic Respiratory Symptoms among Pharmaceutical Factory Workers.

BACKGROUND: Chronic respiratory symptoms including chronic cough, chronic phlegm, wheezing, shortness of breath, and chest pain are manifestations of respiratory problems which are mainly evolved as a result of occupational exposures. This study aims to assess determinants of chronic respiratory symptoms among pharmaceutical factory workers. METHODS: A case control study was carried out among 453 pharmaceutical factory workers with 151 cases and 302 controls. Data was collected using pretested and structured questionnaire. The data was analyzed using descriptive statistics and bivariate and multivariate analysis. RESULT: Previous history of chronic respiratory diseases (AOR = 3.36, 95% CI = 1.85-6.12), family history of chronic respiratory diseases (AOR = 2.55, 95% CI = 1.51-4.32), previous dusty working environment (AOR = 2.26, 95% CI = 1.07-4.78), ever smoking (AOR = 3.66, 95% CI = 1.05-12.72), and service years (AOR = 1.86, 95% CI = 1.16-2.99) showed statistically significant association with chronic respiratory symptoms. CONCLUSION: Previous history of respiratory diseases, family history of chronic respiratory diseases, previous dusty working environment, smoking, and service years were determinants of chronic respiratory symptoms. Public health endeavors to prevent the burden of chronic respiratory symptoms among pharmaceutical factory workers should target the reduction of adverse workplace exposures and discouragement of smoking.
