RÉSUMÉ
Background: Traffic-related air pollution (TRAP) has significant public health implications and a wide range of adverse health effects, including cardiovascular, respiratory, pulmonary, and other health problems. This study aimed to determine the public health impacts of traffic-related air pollution across the world that can be used as an input for protecting human health. Methods: This study considered studies conducted across the world and full-text articles written in English. The articles were searched using a combination of Boolean logic operators (AND, OR, and NOT), MeSH, and keywords from the included electronic databases (SCOPUS, PubMed, EMBASE, Web of Science, CINAHL, and Google Scholars). The quality assessment of the articles was done using JBI tools to determine the relevance of each included article to the study. Results: In this study, 1 282 032 participants ranging from 19 to 452 735 were included in 30 articles published from 2010 to 2022. About 4 (13.3%), 9 (30.0%), 12 (40.0%), 8 (26.7%), 2 (6.7%), 15 (50.0%), 3 (10.0%), 3 (10.0%) 1 (3.3%), and 3 (10.0%) of articles reported the association between human health and exposure to CO, PM10, PM2.5, NOx, NO, NO2, black carbon, O3, PAH, and SO2, respectively. Respiratory diseases, cancer, cognitive function problems, preterm birth, blood pressure and hypertension, diabetes, allergies and sensitization, coronary heart disease, dementia incidence, and hemorrhagic stroke were associated with exposure to TRAP. Conclusions: Exposure to nitrogen dioxide, nitrogen oxide, sulfur dioxide, and fine particulate matter was associated with various health effects. This revealed that there is a need for the concerned organizations to respond appropriately.
RÉSUMÉ
Background: Occupational-related diseases or illnesses account for an estimated 2.4 million deaths worldwide every year. Currently, occupational hazards threaten healthcare workers' (HCWs) lives, safety, and well-being. Therefore, providing the prevalence and major causes of occupational-related diseases may enable injury reduction and the creation of safer working environments, which are important for providing higher quality services. The current study aimed to determine the prevalence of occupational-related injuries and associated risk factors among HCWs, particularly in developing countries. Methods: The articles published in English were retrieved using a combination of Boolean logic operators (AND, OR, and NOT), Medical Subject Headings (MeSH), and keywords in electronic databases (SCOPUS/Science Direct, Web of Science, DOAJ, PubMed/MEDLINE, CINAHL, and Google Scholars). Using Joanna Briggs Institute critical appraisal tools, a quality assessment was conducted to determine the articles' relevance. In addition, the relevant articles were identified through a series of assessment and evaluation stages. Results: About 721 studies were searched using electronic databases, of which 36 articles included 139,578 HCWs. The average prevalence of occupational-related injuries among HCWs in the career and previous last year accounted for 60.17%, ranged from 32% to 87.8% and 39.16%, ranged from 1.14% to 87%, respectively. The current study found that sex and hours worked, stress at work, occupation, age, training in infection prevention, use of universal precautions, recapping needles, ward work experience, staffing and resource adequacy, awareness, outdated guidelines, and previous exposure to sharp injury were statistically associated with occupational-related injuries. Conclusions: This study revealed that 39% and 60% of HCWs experienced occupational-related injuries in the last year and during their career, respectively. Therefore, the appropriate measures must be taken to reduce the burden of occupational-related injuries by following standard precautions or occupational health and safety measures.
