Helicobacter pylori infections in Ethiopia; prevalence and associated factors: a systematic review and meta-analysis.

ABSTRACT:

Background

Helicobacter pylori (H.pylori) infections are prevalent and recognized as major cause of gastrointestinal diseases in Ethiopia. However, Studies conducted on the prevalence, risk factors and other clinical forms of H.pylori on different population and geographical areas are reporting conflicting results. Therefore, this review was conducted to estimate the pooled prevalence of H.pylori infections and associated factors in Ethiopia.

Methods

PubMed, Embase, Google scholar, and Ethiopian Universities' repositories were searched following the Preferred Items for Systematic review and Meta-analysis (PRISMA) guideline. The quality of included studies was assessed using the Newcastle-Ottawa Scale in meta-analysis. Heterogeneity between studies was assessed using Cochrane Q test and I² test statistics based on the random effects model. Comprehensive meta-analysis (CMA 2.0) and Review Manager (RevMan 5.3) were employed to compute the pooled prevalence and summary odds ratios of factors associated with of H.pylori infection.

Results

Thirty seven studies with a total of 18,890 participants were eligible and included in the analysis. The overall pooled prevalence of H.pylori infection was 52.2% (95% CI: 45.8-58.6). In the subgroup analysis by region, the highest prevalence was found in Somalia (71%; 95% CI: 32.5-92.6) and the lowest prevalence was reported in Oromia (39.9%; 95% CI: 17.3-67.7). Absence of hand washing after toilet (OR?=?1.8, 95% CI; 1.19-2.72), alcohol consumption (OR?=?1.34, 95% CI; 1.03-1.74) and gastrointestinal (GI) symptoms (OR?=?2.23, 95% CI; 1.59-3.14) were associated with H.pylori infection. The trend of H.pylori infection showed a decreasing pattern overtime from 1990 to 2017 in the meta-regression analysis.

Conclusion

The prevalence of H.pylori infection remains high; more than half of Ethiopians were infected. Although the trend of infection showed a decreasing pattern; appropriate use of eradication therapy, health education primarily to improve knowledge and awareness on the transmission dynamics of the bacteria, behavioral changes, adequate sanitation, population screening and diagnosis using multiple tests are required to reduce H.pylori infections. Recognizing the bacteria as a priority issue and designing gastric cancer screening policies are also recommended.

Project description:INTRODUCTION:Preterm birth (PTB) complications are the leading cause of death among neonates globally. The reduction in neonatal mortality is not remarkable in Ethiopia. Therefore, this review will assess the magnitude and associated factors of PTB in Ethiopia. METHODS AND ANALYSIS:The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline will be followed during the systematic review. We will include all observational studies published from 1 January 2009 to 31 December 2019 that examined the level and/or associated factors of any type of PTB among live births in Ethiopia. Inclusion criteria will be all live births, PTB defined as delivery before 37 weeks gestation. The primary outcome will be PTB <37 weeks, and secondary outcomes including PTB <34, <32?and <28 weeks will be analysed. PubMed and Science Direct databases as well as Google search engine and Google Scholar will be searched. The pooled prevalence of preterm and effect size of association for associated factors will be analysed using the Stata software V.14. The heterogeneity between studies will be measured by I2 statistics. A random-effects model will be used to estimate if heterogeneity detected. Publication bias will be assessed using a funnel plot. Subgroup analysis will be sought based on possible characteristics of the studies, specific morbidity (like pre-eclampsia, hypertension), type of PTB (spontaneous or iotrogenic) and quality of study (high-quality or low-risk). Meta-regression will be considered for major covariates (maternal age and maternal body mass index) related to PTB. Forest plots will be used to present the combined estimate with 95% CIs. The quality of evidence of the outcomes will be assessed with the GRADE (Grading of Recommendations, Assessment, Development and Evaluations) approach. ETHICS AND DISSEMINATION:No ethical approval is necessary for this systematic review. The findings will be published in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER:CRD42017077356.

Project description:BackgroundGlobally, post-partum depression is a major public health problem and is associated with a harmful effect on the infant, child, and mothers' mental, physical, and social health. Although a few post-partum depression studies have been published, we still lack an accurate estimated pooled prevalence of national PPD and associated factors.ObjectivesThis study aims to show the estimated pooled prevalence of PPD and associated factors in Ethiopia.MethodsWe conduct the extensive search of articles as indicated in the guideline (PRISMA), reporting systematic review and meta-analysis. Databases like MEDLINE, PubMed, psych INFO, Web of Science, EMBASE, CINAHL, Scopus, and The Cochrane Library. All publications and grey literature were addressed by using MeSH terms and keywords. The pooled estimated effect of post-partum depression and associated factors was analyzed using the random effect model meta-analysis, and 95% CI was also considered.Protocol and registrationPROSPERO 2020 CRD42020176769 Available from https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42020176769.ResultA total of 11 studies with 7,582 participants were included in this meta-analysis. The estimated pooled prevalence of post-partum depression (PPD) was 22.08%, with a 95% CI (17.66%, 26.49). For factors associated with post-partum depression, a random effect size model was used during meta-analysis; unplanned pregnancy [(OR = 2.84; 95% CI (2.04, 3.97)], domestic violence [OR = 3.14; 95% CI (2.59, 3.80)], and poor social support [OR = 3.57;95% CI (2.29,5.54) were positively associated factors with post-partum depression.Conclusion and recommendationThe estimated pooled prevalence of post-partum depression was high in Ethiopia. Unplanned pregnancy, poor social support, and domestic violence were factors affecting PPD. Therefore, the Ethiopian policymakers and health personnel better give more emphasis to mothers who had a history of unplanned pregnancy, domestic violence, and poor social support.

Project description:BackgroundTrachoma is the commonest infectious cause of blindness. It is prevalent in areas where personal and community hygiene is poor, and it mainly affects deprived and marginalized communities most importantly in Ethiopia. Hence, the aim of this study was to determine the prevalence and associated factors of active trachoma among children in Ethiopia.MethodA systematic review and meta-analysis was employed to determine the prevalence of active trachoma and associated factors among children in Ethiopia. We searched databases, including PubMed, Google Scholar, Science Direct, EMBASE and Cochrane Library. To estimate the prevalence, studies reporting the prevalence of active trachoma and its associated factors were included. Data were extracted using a standardized data extraction format prepared in Microsoft excel and the analysis was done using STATA 14 statistical software. To assess heterogeneity, the Cochrane Q test statistics and I2 test were used. Since the included studies revealed considerable heterogeneity, a random effect meta- analysis model was used to estimate the pooled prevalence of active trachoma. Moreover, the association between factors and active trachoma were examined.ResultsThe result of 30 eligible studies showed that the overall prevalence of active trachoma among children in Ethiopia was 26.9% (95% CI: 22.7, 31.0%). In the subgroup analysis, while the highest prevalence was reported in SNNP (35.8%; 95% CI: 22.7, 48.8), the lowest prevalence was reported in Oromia region (20.2%; 95% CI: 12.2, 28.2). Absence of latrine: OR 6.0 (95% CI 2.0, 17.5), the unclean faces of children: OR 5.5 (95% CI 2.8, 10.9), and no reported use of soap for washing: OR 3.3 (95% CI 1.8, 6.0) have shown a positive association with active trachoma among children.ConclusionFrom this review, it has been concluded that active trachoma among children is still a public health problem in different districts of Ethiopia. The prevalence of almost all studies are significantly higher than WHO target for elimination. Absence of latrine, unclean faces of children, no reported use of soap for washing are the important factors associated with active trachoma among children.

Project description:BackgroundAnemia is the reduction of red blood cells in size and numbers and an indicator of both poor nutrition and poor health. It is a major global public health problem. Anemia in adolescents and young adults can have negative effects on their cognitive performance and growth. In Ethiopia, previous studies yielded variable prevalence. This review aimed to determine the pooled prevalence of adolescent girls' anemia and associated factors in Ethiopia.MethodsWe searched for studies reporting anemia and associated factors among adolescent girls as reported in peer reviews publications in Ethiopia from 1988 to 2021 from PubMed, Google Scholar, Web of Science, Science Direct, Cochrane Library, and Worldwide Science database. The search strategy identified 309 cross-sectional studies. After screening for potentially eligible articles, we identified 37 publications for full text review, following which 10 publications were included in the final review. Using data from the review, we performed meta-analysis to produce pooled estimates and assess the prevalence of anemia and associated risk factors. Data were extracted using a standardized data extraction format prepared in Microsoft Excel™ and transferred to Stata ™ Version 14.0 for management and further analysis. To identify the source of heterogeneity, subgroup analysis using sample size and study setup was computed, and I2 test was used to declare the presence or absence of significant heterogeneity during subgroup analysis. A random-effect meta-analysis model was used to estimate the pooled prevalence of adolescent girls' anemia. Moreover associated factors for adolescent anemia were assessed too.ResultsThe overall pooled prevalence of anemia among adolescent girls' in Ethiopia was 23.02% (95% CI: 17.21to 28.84). In the subgroup analysis, studies that have a higher sample size than mean have a higher pooled prevalence (27.35%) (95% CI: 21.42 to 33.28) compared to their counterparts. Age being 15-19 (OR: 2.13; 95% CI: 1.52 to 2.96), living in rural areas (OR: 2.05; 95% CI: 1.66 to 2.54), and low dietary diversity (OR: 1.35; 95% CI: 1.00 to 2.34), were the identified factors associated with anemia among adolescent girls'.ConclusionThe pooled prevalence of anemia among adolescent girls in Ethiopia was moderately high. Being in 15-19 years, rural residence, and low dietary diversity score were found to be the significant factors of anemia among adolescent girls in Ethiopia.

Project description:BackgroundSyphilis remained a major cause of reproductive morbidity and poor pregnancy outcomes in developing countries. Previously, studies showed inconsistent results and failed to show the actual picture of the diseases in Ethiopia. Thus, the aim of this meta-analysis was, first, to determine the updated pooled prevalence of syphilis among pregnant women in Ethiopia and, second, to assess its associated factors.MethodsA comprehensive search was made on PubMed, Google scholar, Science Direct, and African Journals Online databases to identify relevant articles. A random effects model was used to estimate pooled syphilis prevalence and odds ratio (OR) with the respective 95% confidence intervals (CIs) using STATA 14 statistical software. I2 statistics and Egger's regression test in conjunction with funnel plot was used to determine heterogeneity and publication bias among included studies respectively.ResultWe identified 13 suitable studies in this analysis. Accordingly, the pooled prevalence of syphilis among pregnant women in Ethiopia was 2.32% (95% CI, 1.68-2.97). Specifically, syphilis prevalence was 2.53% (95% CI, 1.92-3.14%) and 1.90% (95% CI, 0.40-3.40%) as per the treponemal and non-ytreponemal diagnostic test, respectively. On the other hand, regional analysis indicated that 4.06% (95% CI, 2.86-5.26) in Southern Nations Nationalities and Peoples (SNNP), 2.16% (95% CI, 1.57-2.75) in Amhara and 1.46% (95% CI, 0.69-2.23) in Oromia region. Being married (OR, 0.37 (95% CI, 0.12-0.91%)) was less likely to develop syphilis. On the other hand, women with history of multiple sexual partner (OR, 2.98 (95% CI, 1.15-7.70)) and women with history of previous sexually transmitted infection (STI) (OR, 4.88 (95% CI, 1.35-17.62)) have higher risk to develop syphilis. Besides, the pooled syphilis-HIV coinfection was 0.80% (95% CI, 0.60-1.01%).ConclusionThis study provides evidence of relatively high prevalence of syphilis among pregnant women in Ethiopia. Therefore, it is recommended to further ramping up of current intervention measures to prevent future generations.Systematic review registrationPROSPERO CRD42020211650.

Project description:BACKGROUND & AIMS:In 2017, the World Health Organization (WHO) designated clarithromycin-resistant Helicobacter pylori a high priority for antibiotic research and development. However, there are no clear data on the global distribution of resistance or its clinical effects. We performed a systematic review and meta-analysis to assess the distribution of H pylori resistance to commonly used antibiotics and to measure the association between antibiotic resistance and treatment failure. METHODS:We searched publication databases for studies that assessed rates of H pylori resistance to clarithromycin, metronidazole, levofloxacin, amoxicillin, or tetracycline. Pooled estimates of primary and secondary resistance and 95% confidence intervals (CIs) were grouped by WHO region. The association between antibiotic resistance and treatment failure was measured by extracting data on treatment efficacy in patients with resistant and susceptible isolates and pooling odds ratios with 95% CIs. RESULTS:We identified 178 studies, comprising 66,142 isolates from 65 countries. Primary and secondary resistance rates to clarithromycin, metronidazole, and levofloxacin were ?15% in all WHO regions, except primary clarithromycin resistance in the Americas (10%; 95% CI, 4%-16%) and South-East Asia region (10%; 95% CI, 5%-16%) and primary levofloxacin resistance in the European region (11%; 95% CI, 9%-13%). There was considerable heterogeneity (I2 > 75%) among all analyses-this might have resulted from the grouping of resistance rates by country. Increasing antibiotic resistance was observed in most WHO regions. Resistance to clarithromycin was significantly associated with failure of clarithromycin-containing regimens (odds ratio, 6.97; 95% CI, 5.23-9.28; P < .001). CONCLUSIONS:Resistance of H pylori to antibiotics has reached alarming levels worldwide, which has a great effect on efficacy of treatment. Local surveillance networks are required to select appropriate eradication regimens for each region.

Project description:BackgroundSurgical site infection (SSI) affects nearly one third of patients who have undergone a surgical procedure. It is a significant and substantial cause of surgical patient morbidity and mortality later with human and financial costs threat. There are fragmented and pocket studies which reported the prevalence of SSI among mothers who experienced for cesarean section and its risk factors. However, there is no any solid evidence established at the national level; which was also the interest of the authors to fill this gap. Therefore, this systematic review and meta-analysis aimed to estimate the pooled prevalence of SSI after cesarean section and its associated factors at national level.MethodsOriginal articles were searched in PubMed, MEDLINE, EMBASE, CINAHL, Google Scholar, HINARI portal, and Cochrane Library. All observational studies defined outcome of variable "SSI as infection related to an operation procedure that occur at or near surgical incision within 30 days of operation or after one year if an implant is placed" were considered. Data were extracted using standard data extraction excel spread sheet checklists developed according to 2014 Joanna Briggs Institute Reviewers' Manual after the quality was assessed through Newcastle-Ottawa quality assessment scale. The I2 statistic was used to quantify heterogeneity across studies. Funnel plot asymmetry and Egger's tests were used to check for publication bias. A fixed effect model was used to estimate the pooled prevalence of SSI. Odds Ratio (OR) with 95% Confidence Interval (CI) was also considered to determine the association of identified variables with SSI. Statistical analysis was conducted using STATA version 14 software.ResultFrom initial 179 identified articles, 11 were eligible for inclusion in the final systematic review and meta-analysis. Studies with a score of 6 and above were included for final analysis. All included studies were institutional based cross sectional. The pooled estimate of SSI after cesarean section in Ethiopia was 9.72% (95%CI: 8.38, 11.05). Premature rapture of membrane (PROM) >?12?h (OR?=?5.32, 95%CI: 3.61, 7.83), duration of labor>?24?h (OR?=?3.67, 95%CI: 2.45, 5.48), chorioamnionitis (OR?=?9.11, 95%CI: 5.21, 15.93), anemia (OR?=?4.56, 95%CI: 2.88, 7.22) and having vertical skin incision (OR?=?4.17, 95%CI: 2.90, 6.02) had increased odds of developing SSI after cesarean section.ConclusionThe prevalence of SSI after cesarean section in Ethiopia was high compared with the sphere standards of communicable disease control (CDC) guidelines for SSI after cesarean section. Therefore, Ministry of Health with its stake holders should give special emphasis on community and institution based programs in manner to prevent prolonged labor, PROM, chorioamnionitis and anemia which will also have synergistic impact on SSI after cesarean section. Moreover, there is also a call to health professionals not to use vertical incision as primary option of cesarean section to reduce the risk of developing surgical site infection among mothers.

Project description:BackgroundA number of primary studies in Ethiopia address the prevalence of birth asphyxia and the factors associated with it. However, variations were seen among those studies. The main aim of this systematic review and meta-analysis was carried out to estimate the pooled prevalence and explore the factors that contribute to birth asphyxia in Ethiopia.MethodsDifferent search engines were used to search online databases. The databases include PubMed, HINARI, Cochrane Library and Google Scholar. Relevant grey literature was obtained through online searches. The funnel plot and Egger's regression test were used to see publication bias, and the I-squared was applied to check the heterogeneity of the studies. Cross-sectional, case-control and cohort studies that were conducted in Ethiopia were also be included. The Joanna Briggs Institute checklist was used to assess the quality of the studies and was included in this systematic review. Data entry and statistical analysis were carried out using RevMan 5.4 software and Stata 14.ResultAfter reviewing 1,125 studies, 26 studies fulfilling the inclusion criteria were included in the meta-analysis. The pooled prevalence of birth asphyxia in Ethiopia was 19.3%. In the Ethiopian context, the following risk factors were identified: Antepartum hemorrhage(OR: 4.7; 95% CI: 3.5, 6.1), premature rupture of membrane(OR: 4.0; 95% CI: 12.4, 6.6), primiparas(OR: 2.8; 95% CI: 1.9, 4.1), prolonged labor(OR: 4.2; 95% CI: 2.8, 6.6), maternal anaemia(OR: 5.1; 95% CI: 2.59, 9.94), low birth weight(OR = 5.6; 95%CI: 4.7,6.7), meconium stained amniotic fluid(OR: 5.6; 95% CI: 4.1, 7.5), abnormal presentation(OR = 5.7; 95% CI: 3.8, 8.3), preterm birth(OR = 4.1; 95% CI: 2.9, 5.8), residing in a rural area (OR: 2.7; 95% CI: 2.0, 3.5), caesarean delivery(OR = 4.4; 95% CI:3.1, 6.2), operative vaginal delivery(OR: 4.9; 95% CI: 3.5, 6.7), preeclampsia(OR = 3.9; 95% CI: 2.1, 7.4), tight nuchal cord OR: 3.43; 95% CI: 2.1, 5.6), chronic hypertension(OR = 2.5; 95% CI: 1.7, 3.8), and unable to write and read (OR = 4.2;95%CI: 1.7, 10.6).ConclusionAccording to the findings of this study, birth asphyxia is an unresolved public health problem in the Ethiopia. Therefore, the concerned body needs to pay attention to the above risk factors in order to decrease the country's birth asphyxia.Review registrationPROSPERO International prospective register of systematic reviews (CRD42020165283).
