Epidemiology of podoconiosis in Ethiopia: a systematic review and meta-analysis protocol.

ABSTRACT:

Introduction

Podoconiosis is a non-filarial swelling of the lower extremity endemic in tropical regions, North America and India. The aetiology and pathophysiology of the disease remain unknown. We propose conducting a systematic review and meta-analysis to evaluate the burden and risk factors of podoconiosis in Ethiopia reported in studies from 2009 to 2019.

Methods and analysis

We will search the following electronic databases: PubMed (MEDLINE), EMBASE, Hinari, Cumulative Index to Nursing and Allied Health Literature, ISI (Web of Science) and Google Scholar. Medical subject headings will be used to extensively search relevant literature on electronic databases using related keywords such as epidemiology or prevalence, magnitude or burden, podoconiosis, and Ethiopia. Grey literature and manual search will also be performed to retrieve unindexed research articles. Two reviewers will screen all retrieved articles, conduct data extraction and then critically appraise all identified studies. We will analyse data using STATA V.14 statistical software. We will demonstrate pooled estimates of podoconiosis and associated factors with effect size and 95% CI. The presence of heterogeneity among studies will be examined by forest plot as well as the I² heterogeneity test. Potential causes of heterogeneity will be explored by carrying out sensitivity and subgroup analyses. The presence of publication bias will also be examined by observing funnel plots and objectively by Egger's regression test. If the funnel plot is asymmetric and/or Egger's test was found to be statistically significant (p<0.05), the trim and fill (Duval and Tweedie's) analysis will be performed.

Ethics and dissemination

The study will use publicly available data and will not identify the authors of the publication by name. In light of these and as has been indicated, research ethics clearance is not required for evidence syntheses in such reviews. The results of this study will be published in a peer-reviewed journal and presented at national and international conferences.

Project description:BackgroundPodoconiosis is one of the few diseases that could potentially be eliminated within one generation. Nonetheless, the global distribution of the disease remains largely unknown. The global atlas of podoconiosis was conceived to define the epidemiology and distribution of podoconiosis through dedicated surveys and assembling the available epidemiological data.MethodsWe have synthesized the published literature on the epidemiology of podoconiosis. Through systematic searches in SCOPUS and MEDLINE from inception to February 14, 2018, we identified observational and population-based studies reporting podoconiosis. To establish existence of podoconiosis, we used case reports and presence data. For a study to be included in the prevalence synthesis, it needed to be a population-based survey that involved all residents within a specific area. Studies that did not report original data were excluded. We undertook descriptive analyses of the extracted data. This study is registered with PROSPERO, number CRD42018084959.ResultsWe identified 3,260 records, of which 27 studies met the inclusion criteria. Podoconiosis was described to exist or be endemic in 32 countries, 18 from the African Region, 3 from Asia and 11 from Latin America. Overall, podoconiosis prevalence ranged from 0·10% to 8.08%, was highest in the African region, and was substantially higher in adults than in children and adolescents. The highest reported prevalence values were in Africa (8.08% in Cameroon, 7.45% in Ethiopia, 4.52% in Uganda, 3.87% in Kenya and 2.51% in Tanzania). In India, a single prevalence of 0.21% was recorded from Manipur, Mizoram and Rajasthan states. None of the Latin American countries reported prevalence data.ConclusionOur data suggest that podoconiosis is more widespread in the African Region than in the rest of the regions, although this could be related to the fact that most podoconiosis epidemiological research has been focused in the African continent. The assembled dataset confirms that comprehensive podoconiosis control strategies such as promotion of footwear and personal hygiene are urgently needed in endemic parts of Africa. Mapping, active surveillance and a systematic approach to the monitoring of disease burden must accompany the implementation of podoconiosis control activities.

Project description:BACKGROUND:Globally, complications of preterm birth are among the most common cause of neonatal mortality. In Ethiopia, the neonatal mortality reduction is not worthy of attention. Hence, this study reviewed the prevalence of preterm birth and factors associated with preterm birth in Ethiopia. METHODS:The review protocol of this study has been registered in PROSPERO (CRD42017077356). The PRISMA guideline was followed for this review. Studies that assessed the prevalence and/or associated factors of preterm birth in Ethiopia and published from Jan 01, 2009 to Dec 31, 2019 were considered. Studies were searched from the PubMed and Science Direct among medical electronic databases and Google Scholar. Random-effects model was used for detected heterogeneity among studies. Publication bias and sensitivity analysis were assessed. Pooled estimates with its 95% confidence interval were reported using forest plots. The quality of evidence from the review was assessed using GRADE approach. RESULTS:Twenty-two studies involving a total of 12,279 participants were included. The overall pooled prevalence of preterm birth in Ethiopia was 10.48% (95% CI: 7.98-12.99). Pooled odds ratio showed rural residence (AOR?=?2.34, 95% CI: 1.35-4.05), being anemic (AOR?=?2.59, 95% CI: 1.85-3.64), <?4 antenatal care visits (AOR?=?2.34, 95%CI: 1.73-3.33), pregnancy induced hypertension (AOR?=?3.49, 95% CI: 2.45-4.97), prelabor rapture of membrane (AOR?=?4.42, 95% CI: 2.28-8.57), antepartum hemorrhage (AOR?=?5.02, 95% CI: 2.90-8.68), multiple pregnancies (AOR?=?3.89, 95% CI: 2.52-5.99), past adverse birth outcomes (AOR?=?3.24, 95% CI: 2.53-4.15) and chronic illness (AOR?=?4.89, 95%CI: 3.12-7.66) were associated with increased likelihood of preterm birth. Further, support during pregnancy was associated with reduced occurrence of preterm birth. CONCLUSION:The pooled national level prevalence of preterm birth in Ethiopia is high. Socio demographic, nutritional, health care, obstetric and gynecologic, chronic illness and medical conditions, behavioral and lifestyle factors are the major associated factors of preterm birth in Ethiopia. This evidence is graded as low grade. Thus, efforts should be intensified to address reported risk factors to relieve the burden of preterm birth in the study setting, Ethiopia.

Project description:Hepatitis C virus (HCV) morbidity appears to be high in Mongolia. Yet, the scale and nature of the infection burden is not well-understood. Our study's objective is to systematically review and synthetize all available epidemiological data on HCV antibody (Ab) prevalence, ribonucleic acid (RNA) prevalence, incidence, risk factors to HCV exposure, and circulating HCV genotypes/subtypes among different at-risk populations. Additionally, we aim to estimate national population-level HCV-Ab prevalence and the number of HCV chronically infected individuals in the population of Mongolia.Our systematic review will be reported based on the items outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA 2009) statement. All reports with primary data collected from surveillance or observational studies on Mongolian populations will be eligible for inclusion if the study sample size is greater than 25. Included reports need to present studies that use biological assay for HCV-Ab ascertainment. We will consider three primary outcomes of interest: HCV-Ab incidence, HCV-Ab prevalence, and HCV genotypes/subtypes among different at-risk populations. In addition, two secondary outcomes of interests will be also collected: HCV RNA prevalence, and unadjusted and/or adjusted statistically significant risk factors for HCV exposure (p value ≤0.05). In order to identify relevant reports, we will search PubMed, Embase, and Index Medicus for the Southeast Asian region. Additionally, we will search Mongolian scientific and medical journals not indexed in PubMed or Embase and the archives of Mongolian local conferences. Lastly, the literature search will be supplemented by checking references of the included reports and identified reviews. We will use broad search criteria with no language or time restrictions. Meta-analyses will estimate pooled HCV-Ab prevalence (by at-risk population, sex, age group, and period), and pooled RNA prevalence among HCV-Ab positive individuals in the general population. Age-adjustment of estimates will be conducted.The proposed systematic review and meta-analysis will produce a comprehensive synthesis of HCV epidemiology in Mongolia. The study will provide empirical evidence to inform health policy decision-making, resource allocation, and planning and implementation of relevant public health interventions.We have not registered with PROSPERO.

Project description:BackgroundGlobally, excessive alcohol consumption is a major public health problem and is associated with social, mental, physical and legal consequences. However, no systematic review and meta-analysis has been performed to report the consolidated magnitude of alcohol consumption in Ethiopia.MethodsPubMed, EMBASE, and SCOPUS were systematically searched to identify pertinent studies. Subgroup and sensitivity analysis was conducted and Cochran's Q- and the I2 test were used to assess heterogeneity. Publication bias was evaluated by using Egger's test and visual inspection of the symmetry in funnel plots.ResultsWe included 26 articles with a total of 42,811 participants. The pooled current and lifetime prevalence of alcohol consumption was 23.86% (95%CI; 17.53-31.60) and 44.16% (95%CI; 34.20-54.62), respectively. The pooled prevalence of hazardous alcohol consumption was 8.94% (95%CI; 3.40-21.50). The prevalence of hazardous alcohol consumption was remarkably higher in men (11.58%) than in women (1.21%). The prevalence of current and lifetime alcohol consumptions among university students were 22.08% & 38.88% respectively. The pooled data revealed that male sex was found to be a significant predictor of hazardous alcohol consumption (OR 10.38; 95%CI 3.86 to 27.88) as well as current (OR 2.45; 95%CI 1.78 to 3.38) and lifetime (OR 2.14; 95%CI 1.39 to 3.29) consumption. The magnitude of alcohol consumption among university students was apparently lower than the magnitude in other population of the country. The current study suggested a remarkable recent increment in the magnitude of hazardous alcohol consumption in Ethiopia.ConclusionThe current study revealed that the prevalence of alcohol consumption in Ethiopia is comparable with the global estimates of alcohol consumption from the World Health Organization (WHO). The prevalence of hazardous alcohol consumption was remarkably higher in men (11.58%) than in women (1.21%). Male sex was found to be a significant predictor of alcohol consumption. The present study also suggested considerable recent increment in the magnitude of hazardous alcohol consumption in Ethiopia.

Project description:BackgroundEthiopia is one of the scarce African countries where Plasmodium vivax and P. falciparum co-exist. There has been no attempt to derive a robust prevalence estimate of P. vivax in the country although a clear understanding of the epidemiology of this parasite is essential for informed decisions. This systematic review and meta-analysis, therefore, is aimed to synthesize the available evidences on the distribution of P. vivax infection by different locations/regions, study years, eco-epidemiological zones, and study settings in Ethiopia.MethodsThis study was conducted in accordance with Preferred Reposting Items for Systematic Reviews and Meta Analyses (PRISMA) guidelines. Studies conducted and published over the last two decades (2000 to 2020) that reported an estimate of P. vivax prevalence in Ethiopia were included. The Cochrane Q (χ2) and the I2 tests were used to assess heterogeneity, and the funnel plot and Egger's test were used to examine publication bias. A p-value of the χ2 test <0.05 and an I2 value >75% were considered presence of considerable heterogeneity. Random effect models were used to obtain pooled estimate of P. vivax infection prevalence. This study is registered with PROSPERO (International Prospective Register of Systematic Reviews): ID CRD42020201761.ResultsWe screened 4,932 records and included 79 studies that enrolled 1,676,659 confirmed malaria cases, from which 548,214 (32.69%) were P. vivax infections and 1,116,581 (66.59%) were due to P. falciparum. The rest were due to mixed infections. The pooled estimate of P. vivax prevalence rate was 8.93% (95% CI: 7.98-9.88%) with significant heterogeneity (I2 = 100%, p<0.0001). Regional differences showed significant effects (p<0.0001, and I2 = 99.4%) on the pooled prevalence of P. vivax, while study years (before and after the scaling up of interventional activities) did not show significant differences (p = 0.9, I2 = 0%). Eco-epidemiological zones considered in the analysis did show a significant statistical effect (p<0.001, I2 = 78.5%) on the overall pooled estimate prevalence. Also, the study setting showed significant differences (p = 0.001, and I2 = 90.3%) on the overall prevalence, where significant reduction of P. vivax prevalence (4.67%, 95%CI: 1.41-7.93%, p<0.0001) was observed in studies conducted at the community level. The studies included in the review demonstrated lack of publication bias qualitatively (symmetrical funnel plot) and quantitatively [Egger's test (coefficient) = -2.97, 95% CI: -15.06-9.13, p = 0.62].ConclusionThe estimated prevalence of P. vivax malaria in Ethiopia was 8.93% with P. vivax prevailing in the central west region of Ethiopia, but steadily extending to the western part of the country. Its distribution across the nation varies according to geographical location, study setting and study years.

Project description:BackgroundPostnatal depression is among the common mental health problems that occur during the postnatal period. However, it is left undiagnosed in low- and middle-income countries including Ethiopia. Therefore, this systematic review and meta-analysis aimed to systematically summarize the available evidence on the epidemiology of postnatal depression in Ethiopia and suggest recommendations for future clinical practice.MethodsThe Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline was followed to conduct this systematic review and meta-analysis. We searched PubMed, SCOPUS, EMBASE and Google Scholar databases for the relevant articles that assessed the prevalence of postnatal depression in Ethiopia. We used a random-effect model to conduct a meta-analysis. We conducted a subgroup and sensitivity analysis to explore the source of heterogeneity. Cochrane Q- and the I2-test were used to check the heterogeneity of the included studies. The presence of publication bias was also checked by visual inspection of symmetry and Egger's test.ResultsThe pooled estimated prevalence of postnatal depression in Ethiopia was 20.1% (95% CI 12.7-30.2). The pooled prevalence of postnatal depression in the studies that were conducted in community settings and used the Patient Health Questionnaire to assess postnatal depression [16.6% (95% CI 8.90-28.99)] was lower than the prevalence in studies based in institutions and that used the Edinburgh Postnatal Depression Scale [23.2% (95% CI 14.50-28.5)]. Further, in a leave-one-out sensitivity analysis the prevalence of postnatal depression ranges between 15.4% and 25.4%. Unplanned pregnancy [AOR = 3.46, 95% CI (2.37-5.04)], age between 15-24 years [AOR = 1.72, 95% CI (1.11-2.68)], marital problems [AOR = 3.07, 95% CI (2.36-3.99)], experiencing the death of infant [AOR = 3.41, 95% CI (1.91-6.09)] and history of substance use [AOR = 3.47, 95% CI (2.17-5.56)] were associated with the increased odds of postnatal depression in Ethiopia.ConclusionThe prevalence of postnatal depression in Ethiopia was high. Therefore, the concerned body should give due attention to improve reproductive health services through early detection of risk factors of postnatal depression.
