Perceived occupational stress and associated factors among primary school teachers in the second wave of COVID-19 in Ethiopia: a multicenter cross-sectional survey

BackgroundOccupational stress (OS) is a psychological state that results from people’s perceptions of an imbalance between job demands and their abilities to cope with those demands. The COVID-19 pandemic has disrupted the teaching and learning process and compounded the stress level among teachers due to fear of transmission of the virus and school closures or the difficulty with adherence to the COVOD-19 prevention protocol. This survey study therefore aimed to investigate the prevalence of occupational stress and its associated factors among primary school teachers during the second wave of COVID-19 in western Ethiopia.MethodAn institution-based cross-sectional survey was employed from April to May 2021. The survey was conducted in Gimbi town among all 672 primary school teachers in western Ethiopia. The standardized Teacher Occupational Stress Scale was used to measure occupational stress in the past 4 months. The data were collected through a self-administered questionnaire. The collected data were entered into EpiData version 4.6 and analyzed using Stata version 14 software. A multivariable logistic regression analysis was conducted to identify factors associated with occupational stress. The statistical significance was considered at a value of p of < 0.05 and a 95% confidence interval (CI) with an adjusted odds ratio (AOR) to evaluate the strength of associations.ResultsThe response rate was 96.8% (N = 651). The majority, 389 (59.8%) of the study participants were males. The mean (±SD) age was 35.8 (±9.3) years. The prevalence of occupational stress in the second wave of COVID-19 in the past 4 months was 50.1% (n = 326) [95% CI (46.1, 53.9)]. Job dissatisfaction [AOR: 2.06, 95% CI (1.43–2.97)] and high-risk perception of COVID-19 infection [AOR: 2.20; 95% CI (1.46–3.31)] were significantly associated with occupational stress.ConclusionThis survey disclosed a high prevalence of occupational stress among primary school teachers during the second wave of COVID-19. Job dissatisfaction and a high-risk perception of COVID-19 infection were significant predictors of the occurrence of occupational stress in school teachers. Enhancing stress management skills and focusing on primary prevention of identified risk factors were advised to curtail the condition

A systematic review of the health effects of lead exposure from electronic waste in children

IntroductionElectronic waste (e-waste) is an emerging human and environmental problem. Lead (Pb) is one of the most dangerous chemicals for human health, and it is the most prevalent heavy metal pollutant in e-waste. Despite the rapid growth of e-waste globally and the health effects of Pb, there is little information regarding the effects of Pb exposure from e-waste on children. Therefore, the aim of this review was to provide concise information on the health effects of Pb exposure from e-waste on children.MethodsA comprehensive search of databases was undertaken using PubMed/MEDLINE, Cochrane Library, Science Direct, HINARI, African Journal Online (AJOL), and additional sources were searched up to November 25, 2022. Eligibility criteria were determined using Population, Exposure, Comparator, and Outcome (PECO). The guidelines for Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) were used during the article selection process. The protocol of this systematic review was registered in the International Prospective Register of Systematic Reviews (Registration ID: CRD42022377028). The Joanna Briggs Institute (JBI) quality appraisal checklist was used to assess the quality of the included studies.ResultsFrom a total of 1,150 identified studies, 20 full-text studies were included in the systematic review. All most included studies were conducted in China recycling area for e-waste. The included studies were conducted with an exposed group versus a reference group. The majority of the included studies found that blood Pb levels were ≥5 μg/dl and that Pb exposures from e-waste were affecting children’s health, such as a decrease in serum cortisol levels, inhibition of hemoglobin synthesis, impact on neurobehavioral development, affect physical development, etc.ConclusionLead exposure had a significant impact on children’s health as a result of informal e-waste recycling. Therefore, formalizing the informal sector and raising public health awareness are important steps toward reducing Pb exposure from e-waste. Moreover, the concerned stakeholders, like national and international organizations, should work together to effectively manage e-waste

Effect of antenatal care on low birth weight: a systematic review and meta-analysis in Africa, 2022

BackgroundRisk identification, as well as the prevention and management of diseases associated with pregnancy or other conditions that may occur concurrently, is the essential component of ANC.MethodThe observational follow-up and cross-sectional studies on the effect of antenatal care on low birth weight in Africa were conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. Five computerized bibliographic databases: Google Scholar, PubMed, Scopus, Cochrane Library, and Hinari Direct were searched for published studies written in English till May 2022. The risk of bias assessment tools developed by the Joanna Briggs Institute for cross-sectional and observational follow-up research was used, and the caliber of each included study was assessed. Seven papers were included, with a total of 66,690 children participating in the study.ResultsSeven studies met the selection criteria. Prenatal care and low birth weight were linked in four of the seven studies included in the review. The pooled odd ratio for low birth weight in the random-effects model was 0.46 (95% CI: 0.39, 0.53). The pooled odds ratio for low birth weight was 0.21 (95% CI: 0.19, 0.22) and 0.21 (95% CI: 0.19, 0.22), respectively, among pregnant women who had no antenatal care follow-up and those who had antenatal care follow up.ConclusionWomen who attended at least one antenatal care appointment were more likely than their counterparts to have a baby of normal weight. Interventions to reduce low birth weight in Africa should focus on providing adequate antenatal care and quality healthcare services to women with low socioeconomic status

Prevalence of diarrheal disease and associated factors among under-five children in flood-prone settlements of Northwest Ethiopia: A cross-sectional community-based study

BackgroundDiarrheal illnesses are a long-standing public health problem in developing countries due to numerous sanitation issues and a lack of safe drinking water. Floods exacerbate public health issues by spreading water-borne infectious diseases such as diarrhea through the destruction of sanitation facilities and contamination of drinking water. There has been a shortage of studies regarding the magnitude of diarrheal disease in flood-prone areas. Therefore, this research aimed to evaluate the prevalence of diarrheal disease and its predictors among under-five children living in flood-prone localities in the south Gondar zone of Northwest Ethiopia.MethodA community-based cross-sectional research was carried out in flood-prone villages of the Fogera and Libokemkem districts from March 17 to March 30, 2021. Purposive and systematic sampling techniques were used to select six kebeles and 717 study units, respectively. Structured and pretested questionnaires were used to collect the data. A multivariable analysis was performed to determine the predictors of diarrheal disease, with P-value <0.05 used as the cut-off point to declare the association.ResultThe prevalence of a diarrheal disease among under-five children was 29.0%. The regular cleaning of the compound [AOR: 2.13; 95% CI (1.25, 3.62)], source of drinking water [AOR: 2.36; 95% CI: (1.26, 4.41)], animal access to water storage site [AOR: 3.04; 95% CI: (1.76, 5.24)], vector around food storage sites [AOR: 9.13; 95% CI: (4.06, 20.52)], use of leftover food [AOR: 4.31; 95% CI: (2.64, 7.04)], and fecal contamination of water [AOR: 12.56; 95% CI: (6.83, 23.20)] remained to have a significant association with diarrheal diseases.ConclusionThe present study found that the prevalence of the diarrheal disease among under-five children was high. Routine compound cleaning, the source of drinking water, animal access to a water storage site, vectors near food storage sites, consumption of leftover food, and fecal contamination of water were significant predictors of diarrheal disease. Therefore, it is advised to provide improved water sources, encourage routine cleaning of the living area, and offer health education about water, hygiene, and sanitation

Global, regional, and national burden of disorders affecting the nervous system, 1990–2021: a systematic analysis for the Global Burden of Disease Study 2021

BackgroundDisorders affecting the nervous system are diverse and include neurodevelopmental disorders, late-life neurodegeneration, and newly emergent conditions, such as cognitive impairment following COVID-19. Previous publications from the Global Burden of Disease, Injuries, and Risk Factor Study estimated the burden of 15 neurological conditions in 2015 and 2016, but these analyses did not include neurodevelopmental disorders, as defined by the International Classification of Diseases (ICD)-11, or a subset of cases of congenital, neonatal, and infectious conditions that cause neurological damage. Here, we estimate nervous system health loss caused by 37 unique conditions and their associated risk factors globally, regionally, and nationally from 1990 to 2021.MethodsWe estimated mortality, prevalence, years lived with disability (YLDs), years of life lost (YLLs), and disability-adjusted life-years (DALYs), with corresponding 95% uncertainty intervals (UIs), by age and sex in 204 countries and territories, from 1990 to 2021. We included morbidity and deaths due to neurological conditions, for which health loss is directly due to damage to the CNS or peripheral nervous system. We also isolated neurological health loss from conditions for which nervous system morbidity is a consequence, but not the primary feature, including a subset of congenital conditions (ie, chromosomal anomalies and congenital birth defects), neonatal conditions (ie, jaundice, preterm birth, and sepsis), infectious diseases (ie, COVID-19, cystic echinococcosis, malaria, syphilis, and Zika virus disease), and diabetic neuropathy. By conducting a sequela-level analysis of the health outcomes for these conditions, only cases where nervous system damage occurred were included, and YLDs were recalculated to isolate the non-fatal burden directly attributable to nervous system health loss. A comorbidity correction was used to calculate total prevalence of all conditions that affect the nervous system combined.FindingsGlobally, the 37 conditions affecting the nervous system were collectively ranked as the leading group cause of DALYs in 2021 (443 million, 95% UI 378–521), affecting 3·40 billion (3·20–3·62) individuals (43·1%, 40·5–45·9 of the global population); global DALY counts attributed to these conditions increased by 18·2% (8·7–26·7) between 1990 and 2021. Age-standardised rates of deaths per 100 000 people attributed to these conditions decreased from 1990 to 2021 by 33·6% (27·6–38·8), and age-standardised rates of DALYs attributed to these conditions decreased by 27·0% (21·5–32·4). Age-standardised prevalence was almost stable, with a change of 1·5% (0·7–2·4). The ten conditions with the highest age-standardised DALYs in 2021 were stroke, neonatal encephalopathy, migraine, Alzheimer's disease and other dementias, diabetic neuropathy, meningitis, epilepsy, neurological complications due to preterm birth, autism spectrum disorder, and nervous system cancer.InterpretationAs the leading cause of overall disease burden in the world, with increasing global DALY counts, effective prevention, treatment, and rehabilitation strategies for disorders affecting the nervous system are needed

Objective This study aimed to investigate the prevalence and risk factors of chronic respiratory symptoms among school teachers in Gondar city, north-western Ethiopia.Design A school-based cross-sectional study was conducted from April to May 2019. A self-administered British Medical Research Council Questionnaire was used to assess chronic respiratory symptoms. Data were entered into Epi Info V.7 and Stata V.14 was used for analysis. A multivariable logistic regression analysis was conducted to identify factors associated with chronic respiratory symptoms. The association was determined using adjusted OR (AOR) with a 95% CI at a value of p<0.05.Setting The study was conducted in public and private schools in Gondar city.Participants A total of 822 teachers participated in this study.Outcome measures The primary outcome is the prevalence of chronic respiratory symptoms.Results The total response rate was 97.4%. The majority, 532 (64.7%) of the participants, were male. The mean age (±SD) of the respondents was 36.69 (±6.93) years. The total prevalence of chronic respiratory symptoms in the previous 12 months among teachers in Gondar city was found to be 31.14% (95% CI 27.99% to 34.43%). A family history of respiratory problems (AOR=1.90; 95% CI 1.07 to 3.37), an overweight body mass index (AOR=2.57; 95% CI 1.57 to 4.21), exposure to secondhand cigarette smoke at home (AOR=9.85; 95% CI 4.77 to 20.33), use of chalk (AOR=1.97; 95% CI 1.25 to 3.09), and failure to open windows during class (AOR=2.15; 95% CI 1.02 to 4.52) were risk factors for chronic respiratory symptoms.Conclusion This study concluded that the prevalence of chronic respiratory symptoms was high among teachers. Making a smoking-free zone, avoiding smoking in public places, improving the ventilation conditions of the classrooms and controlling the chalk dust are all necessary actions to take to reduce chronic respiratory symptoms

Magnitude and influencing factors of work-related low back pain among high school teachers in West Arsi zone, Southwest Ethiopia: evidenced from multicentred cross-sectional study

Objective This study aimed to investigate the prevalence of low back pain and its associated factors among high school teachers in the West Arsi zone, Southwest Ethiopia.Design A school-based cross-sectional study was conducted from February to March 2020. A self-administered structured Nordic Musculoskeletal questionnaire was used to assess low back pain during the past 12 months. Bivariate and multivariable binary logistic regression analysis was carried out using Stata V.14. The degree of significance was obtained at a 95% CI and p<0.05.Setting The study was conducted in the West Arsi zone, Ethiopia.Participants A total of 602 teachers participated in this study.Outcome measures The primary outcome is the prevalence of low back pain.Results The prevalence of low back pain during the last 12 months was found to be 63.73% (95% CI 59.77% to 67.70%). About 225 (39.61%) teachers experienced moderate pain, and (89.79%) of them had a minimal disability. Being unmarried (adjusted OR (AOR) 0.47, 95% CI 0.28 to 0.79), prolonged standing (AOR 2.31, 95% CI 1.16 to 4.60), sleeping disturbance (AOR 3.22, 95% CI 1.41 to 7.36), regular physical activity (AOR 0.52, 95% CI 0.33 to 0.84), current smoker (AOR 2.83, 95% CI 1.04 to 7.67), lifting heavy load (AOR 1.96, 95% CI 1.17 to 3.28), psychological job demand (AOR 2.86, 95% CI 1.69 to 4.84) and job satisfaction (AOR 0.46, 95% CI 0.27 to 0.79) were associated with low back pain.Conclusion The prevalence of low back pain was high in this study. Prolonged standing, sleep disruption, heavy load lifting, cigarette smoking and psychological job demand were risk factors for low back pain. Physical exercise and workplace satisfaction were effective interventions. Emphasis should now be put on ergonomics, regular physical activity and psychosocial factors to lessen the problem

Occupational respiratory morbidity and associated factors among hairdressers in Ethiopia: a cross-sectional study

Objective This study was designed to determine the prevalence and factors associated with occupational respiratory morbidity among hairdressers in Northwestern Ethiopia.Design A cross-sectional study was conducted from 6 July 2022 to 17 August 2022. The data were collected using a standardised American Thoracic Society questionnaire. The collected data were entered into EpiData V.4.6 and analysed using Stata V.14. A multivariable logistic regression analysis was conducted to identify factors associated with occupational respiratory morbidity. The association was determined using an adjusted OR (AOR) with a 95% CI at a p value of <0.05.Setting The study was conducted in Gondar city, Northwestern Ethiopia.Participants A total of 403 hairdressers participated in this study.Outcome measures The primary outcome is the prevalence of occupational respiratory morbidity.Results The total response rate was 95.5%. The majority, 250 (62%) of the respondents were women. The mean age (±SD) of the respondents was 27 (±6.0) years. The overall prevalence of occupational respiratory morbidity during the past 12 months was found to be 134 (33.3%) (95% CI (28.7% to 38.1%)). Female hairdressers (18.6%) showed greater respiratory morbidity than male hairdressers (14.7%). Working experience 3–5 years (AOR: 3.05; 95% CI (1.76 to 5.30)) and working experience >5 years (AOR: 6.22; 95% CI (2.73 to 14.16)), overweight (body mass index (BMI)) (AOR: 3.01; 95% CI (1.19 to 7.58)) and working near roadsides (AOR: 2.15; 95% CI (1.33 to 3.37)) were risk factors of occupational respiratory morbidity among hairdressers.Conclusions This study concluded that one-third of hairdressers experienced occupational respiratory morbidity. Longer work experience, higher BMI and working near roadsides were identified as significant risk factors for respiratory morbidity in hairdressers. Dietary calorie restrictions for overweight individuals and the development and implementation of air pollution mitigation measures targeted at roadside workers are advised to curb the problem

Unimproved source of drinking water and its associated factors: a spatial and multilevel analysis of Ethiopian demographic and health survey

Abstract Background Drinking water quality has been a major public health concern in lower and middle income countries where access to improved water supplies is limited. Ethiopia is thought to have one of the worst drinking water infrastructures in the world. This study aimed to assess the spatial variation and determinants of using unimproved sources of drinking water in Ethiopia using recent nationally representative data. Methods A population-based cross-sectional study was employed with the recent EDHS data of 2019. A total of 8663 households were sampled using a stratified two-stage cluster sampling method. Kuldorff’s SaTScan version 9.6 software was used to generate spatial scan statistics. ArcGIS version 10.7 software was used to visualize the spatial patterns of unimproved drinking water sources. A multilevel multivariable mixed-effect logistic regression was used to identify factors associated with the use of an unimproved drinking water source. In the multivariable multilevel analysis, those variables with a p-value < 0.05 were considered to be significant predictors of using an unimproved source of drinking water. Result Around 31% (95% CI: 30%, 32%) of the population in Ethiopia uses unimproved sources of drinking water with significant spatial variation across the country. Households aged 41–60 [AOR = 0.69; 95%CI; 0.53, 0.89] as compared to the households aged 10–25, households having middle wealth index [AOR = 0.48; 95%CI; 0.40, 0.59], and households having a rich wealth index [AOR = 0.31; 95%CI; 0.25, 0.39] as compared to the poor households, living in high community literacy level [AOR = 0.36; 95%CI; 0.16, 0.80], living in high-level community poverty [AOR = 3.03; 95%CI; 1.32, 6.98], rural residence [AOR = 7.88; 95%CI; 2.74, 22.67] were significant predictors of use of unimproved source of drinking water. Hot spot areas of use of unimproved drinking water sources were observed in Amhara, Afar, and Somalia regions and some parts of SNNPR and Oromia regions in Ethiopia. The primary clusters were found in Ethiopia’s Somalia and Oromia regions. Conclusion Around one third of the Ethiopian population utilizes unimproved source of drinking water and it was distributed non-randomly across regions of Ethiopia. The age of the household head, wealth status of the household, residence, community poverty level, and community literacy level were found to be significantly associated with utilizing unimproved drinking water source. State authorities, non-governmental organizations and local health administrators should work to improve the quality of drinking water particularly for high risk groups such as communities living in high poverty and low literacy, poor households, rural residents, and hot spot areas to decrease the adverse consequences of using unimproved drinking water source
