BACKGROUND: Musculoskeletal disorders are a major source of disability accounting for considerable economic loss globally. Studies showed that housekeepers suffer from exposure to many high-risk factors for neck and upper limb musculoskeletal disorders. In Ethiopia, little is known and the information is limited in scope about the magnitude of the problem among hotel housekeepers. Therefore, this study aimed to determine the magnitude of the neck and upper limb musculoskeletal disorders and identify the associated risk factors among hotel housekeepers. METHODS: Institution-based cross-sectional study design was employed from March 1 to May 20, 2017. Systematic random sampling was used to select 422 study participants among the Gondar town hotels, Ethiopia. The standardized Nordic questionnaire for the analysis of musculoskeletal symptoms was used to measure the neck and upper limb musculoskeletal disorders. Bivariate and multivariable binary logistic regression analyses were performed using SPSS version 20. The significance level was obtained at 95% CI and p value ≤ 0.05. RESULTS: The overall magnitude of a self-reported neck and upper limb musculoskeletal disorders among hotel housekeepers in the last 12 months was 62.8% (95% CI 58.3, 67.8). The main body areas of concern were neck pain (50.7%), shoulder pain (54%), elbow/forearm (47.2%), and hand/wrist (45.5%). Age, rest break taken, repetitive movement, reaching/overstretching, organization concern for health and safety, and job satisfaction were the risk factors significantly associated with neck and upper limb musculoskeletal disorders. CONCLUSIONS A higher proportion of hotel housekeepers were found to be affected by neck and upper limb musculoskeletal disorders in Gondar town. Repetitive movement and reaching/overstretching were strongly associated risk factors with neck and upper limb musculoskeletal disorders. Therefore, ergonomic, organizational and personal measures, which focus on minimizing repetitive movement and awkward working position and facilitating rest break with exercise, are important to tackle neck and upper limb musculoskeletal disorders among hotel housekeepers.

BACKGROUND: Scabies is a skin infestation caused by the mite Sarcoptes scabiei that causes a pruritic skin eruption. In Ethiopia, the disease is common especially during natural or manmade disasters such as flooding, drought, civil war and conflict, poor water supply and sanitation, and overcrowding living condition. Though scabies is becoming a major public health problem, especially in low resource settings, there has been no study that reported the prevalence of scabies in the study area. The aim of this study, therefore, was to assess the prevalence of scabies and associated factors among students in primary schools in Dabat district, northwest Ethiopia. METHOD: An institutional-based cross-sectional study was employed to determine the prevalence of scabies and associated factors among schoolchildren in Dabat district. A total of 494 students selected by a multi-stage sampling technique were included in this study. Scabies was diagnosed by medical practitioners based on lesions observed on body surfaces after a physical examination. Bivariable and multivariable binary logistic regression analyses were performed using SPSS version 20. Significance level was obtained at p value < 0.05. RESULT: The prevalence of scabies was 9.3% (46/494) with 95% CI (5.66%, 12.94%). Among schoolchildren who were infested by scabies, 65.22% (30/46) had a mild, 28.26% (13/46) had moderate, and 6.52% (3/46) had severe lesions. Studying at a rural school (AOR = 2.99, 95% CI 1.33, 6.71), had illiterate father (AOR = 5.11, 95% CI 2.25, 11.58), being grade level 1-4 (AOR = 3.91, 95% CI 1.69, 9.05), rarely taking a bath (AOR = 3.54, 95% CI 1.36, 9.25), contact with a person with itching symptom (AOR = 2.66, 95% CI 1. 21, 5.83), a family member with itchy symptoms (AOR = 4.76, 95% CI 2.20, 10.28), not living with both parents (AOR = 2.49, 95% CI 1.02, 6.06), and using water only for hand washing (AOR = 4.38, 95% CI 1.78, 10.76) were factors associated with scabies infestation among schoolchildren. CONCLUSION The prevalence of human scabies among schoolchildren in Dabat district northwest Ethiopia was high. The school localization, first cycle level of education, paternal educational status, frequency of taking a bath, and contact with a person having itchy lesions, presence of a family member with itchy lesion, and type of frequently used hand washing material were the factors significantly impacting the occurrence of scabies. Special attention should be given to students at first cycle education as they are at the highest risk of infestation.

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.
