Prevalence of Hepatitis C Virus Infection among Pregnant Women in Ethiopia: A Systematic Review and Meta-Analysis.

ABSTRACT:

Background

Hepatitis C virus infection during pregnancy is associated with a high risk of maternal complications and poor birth outcomes. There are variable reports on the prevalence of hepatitis C virus infection among pregnant women in Ethiopia. Therefore, this study aims to estimate the pooled prevalence of hepatitis C virus infection among pregnant women in Ethiopia.

Methods

A comprehensive search of electronic databases including PubMed, Scopus, EMBASE, the Cochrane Library, Web of Sciences, and Google Scholar was conducted from April 03, 2020, to May 03, 2020. The quality of included article was evaluated by the JBI. Heterogeneity between the studies was assessed using Cochrane Q and I ² test. The presence of publication bias was tested by funnel plots and Egger's test. A random-effects meta-analysis was computed to determine the pooled prevalence of HCV infection among pregnant women.

Results

Of 502 studies, 6 studies with a total of 2117 pregnant women were included in the meta-analysis. The overall pooled prevalence of hepatitis C virus infection among pregnant women in Ethiopia was 1.83% (95% CI: 0.61, 3.06). Besides, subgroup analysis revealed that the highest HCV prevalence among pregnant women was observed in Oromia region, 5.10% (95% CI: -0.53, 10.73).

Conclusions

This study shows an intermediate level of HCV infection among pregnant women in Ethiopia. The finding suggests the need of implementing a routine hepatitis C virus screening program for all pregnant women, which enables women to access HCV antiviral treatment to minimize vertical transmission to the newborn infants. Moreover, national and regional health programs should mandate and monitor the screening procedures so as to reduce the risk of hepatitis C virus infection.

Project description:Background:Hepatitis B virus (HBV) is an infectious and a global public health problem. The prevalence of HBV infection among pregnant women is between 2.3% and 7.9%. HBV infection during pregnancy is associated with prenatal transmission to the fetus. HBV has an effective vaccine which reduces up to 96% of the transmission. Although different studies were conducted in Ethiopia, none of them showed the national prevalence of HBV infection among pregnant women. Therefore, this study was conducted to determine the pooled prevalence of HBV and its associated factors in Ethiopia. Methods:We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for articles. All observational published studies were retrieved using relevant search terms in Google Scholar, African Online Journal, CINAHL, and PubMed databases. Newcastle-Ottawa assessment checklist for observational studies was used for critical appraisal of the included articles. The meta-analysis was done with STATA version 14 software. The I 2 statistics were used to test heterogeneity whereas Begg's and Egger's tests were used to assess publication bias. Odds ratio (OR) with a 95% confidence interval (CI) was presented using the forest plot. Results:A total of twenty-three studies were included in this systematic review and meta-analysis. The pooled prevalence of HBV in Ethiopia was 4.75% (95% CI: 4.06, 5.44). The subgroup analysis showed a higher prevalence of HBV infection among pregnant women in Gambella (7.9%) and the lowest in Southern Nations, Nationalities, and Peoples' Region (SNNPR) (2.3%). Associated factors with HBV infection include history of multiple sexual partner (OR = 6.02 (95%CI = 3.86, 9.36)), blood transfusion history (OR = 5.71 (95%CI = 3.25, 10.04)), abortion history (OR = 3.58 (95%CI = 2.10, 6.09)), and history of body tattoo (OR = 2.83 (95%CI = 1.55, 5.17)). Conclusions:HBV infection among pregnant women is a common public health problem in Ethiopia. Multiple sexual partners, abortion history, blood transfusion history, and body tattoo were significantly associated with HBV infection. Policies and strategies should focus on factors identified in this study to improve the prevention of HBV among pregnant women.

Project description:IntroductionAfrica exhibits a considerably high prevalence of the hepatitis B virus among pregnant women. Furthermore, there is a discernible lack of a well-established surveillance system to adequately monitor and comprehend the epidemiology of the hepatitis B virus, particularly among pregnant women. The eradication efforts of the virus in Africa have been impeded by the significant disease burden in the region, and there is a lack of evidence regarding the pooled prevalence of the hepatitis B virus in Africa. Consequently, this systematic review and meta-analysis aims to determine the prevalence of hepatitis B virus infection among pregnant women in Africa.MethodsWe conducted a systematic literature search using reputable databases such as PubMed, Advanced Google Scholar, Scopus, and the Cochrane Library. The search spanned from July 2013 to July 2023 and included all relevant articles published within this period. To identify potentially eligible articles, we conducted a comprehensive manual review of the reference lists of the identified studies. Our review encompassed articles from the African Journal Online. The analysis focused on observational studies published in peer-reviewed journals that reported the prevalence of hepatitis B surface antigen-positive testing among pregnant women. We utilized the Newcastle-Ottawa critical appraisal checklist to assess the methodological quality of each paper. Finally, a meta-analysis was conducted using a random-effects model.ResultsOut of the 774 studies identified, 31 studies involving 33,967 pregnant women were selected for the meta-analysis. According to the random-effects model, the combined prevalence of hepatitis B virus among pregnant women was 6.77% [95% CI: 5.72, 7.83]. The I2 statistic was calculated to be 95.57% (p = 0.00), indicating significant heterogeneity among the studies. The high I2 value of 95.57% suggests a substantial degree of heterogeneity. A subgroup meta-analysis revealed that factors such as time-dependent bias, sample size dependence, or individual variation among study participants contributed to this heterogeneity (p-difference < 0.05).ConclusionAccording to the findings of this study, the pooled prevalence of hepatitis B infection among pregnant women in Africa was found to be intermediate-high. It is recommended that policymakers implement hepatitis B virus immunization programs targeting pregnant women and their new-born babies at higher risk of exposure.

Project description:BackgroundHepatitis B virus infection is a major public health problem among pregnant women worldwide. Hepatitis B virus is highly infectious and is the most common cause of morbidity and mortality among pregnant women, and evidence is scarce on the pooled seroprevalence of hepatitis B virus in Ethiopia.ObjectivesThis study aimed to investigate the pooled seroprevalence of hepatitis B virus infection and factors associated with pregnant women in Ethiopia.DesignA systematic review and meta-analysis was employed in accordance with the Preferred Reporting Items for Systematic Reviews.Data sourcesSearches were carried out in biomedical databases such as PubMed/Medline, Science Direct, Web of Science, Google Scholar, Hinari, and the Cochrane Library published in English until June 2023.MethodsObservational study designs were selected. Endnote citation manager was used to collect and organize the search outcomes and remove duplicate articles. The data were extracted using a Microsoft Excel spreadsheet and exported to STATA 16.0 software for the analysis.ResultsA total of 48 research articles were included in the final analysis. The pooled estimated sero prevalence of hepatitis B virus infection among pregnant women in Ethiopia was 5.78% (95% confidence interval = 5.14, 6.43). History of abortion (odds ratio = 6.56, 95% confidence interval = 4.88, 8.90), history of blood transfusion (odds ratio = 5.74, 95% confidence interval = 4.04, 8.16), history of hospitalization (odds ratio = 5.40, 95% confidence interval = 3.68, 7.94), history of multiple sexual partner (odds ratio = 5.80, 95% confidence interval = 3.71, 9.05), history of surgical procedure (odds ratio = 7.39, 95% confidence interval = 4.16, 13.14), history of tattooing (odds ratio = 4.59, 95% confidence interval = 2.83, 7.43), and history of tooth extraction (odds ratio = 4.46, 95% confidence interval = 2.42, 8.22) were significantly associated with hepatitis B virus infection among pregnant women in Ethiopia.ConclusionThe overall pooled prevalence of hepatitis B virus infection among pregnant women in Ethiopia is relatively high. Having a history of abortion, blood transfusion, hospitalization, multiple sexual partners, surgical procedures, tattooing, and tooth extraction were found to be risk factors for hepatitis B virus. Therefore, extensive screening programs for hepatitis B virus in all pregnant women in Ethiopia are needed to prevent further infection and decrease the vertical transmission caused by the disease.Registration numberPROSPERO CRD: 42023438522.

Project description:BackgroundNigeria has a high burden of hepatitis B virus (HBV) infection, commonly acquired through vertical transmission. However, there is a lack of an efficient surveillance system for monitoring and understanding the epidemiology of HBV among pregnant women. Building on a previous review on the prevalence of HBV in Nigeria (2000-2013), we conducted a systematic review and meta-analysis of HBV prevalence among pregnant women in Nigeria.MethodsFour electronic databases PubMed, Embase, Global Health, and Scopus were systematically searched from January 2014 to February 2021. We also searched the African Journal Online and manually scanned the reference lists of the identified studies for potentially eligible articles. Observational studies that reported the prevalence of HBsAg and/or HBeAg among pregnant women in peer-reviewed journals were included in the study. We performed a meta-analysis using a random-effects model. We defined HBV infection as a positive test to HBsAg.ResultsFrom the 158 studies identified, 20 studies with a total sample size of 26, 548 were included in the meta-analysis. The pooled prevalence of HBV infection among pregnant women across the studies was 6.49% (95% confidence interval [CI] = 4.75-8.46%; I2 = 96.7%, p = 0.001; n = 20). The prevalence of HBV was significantly lower among pregnant women with at least secondary education compared with those with no education or primary education (prevalence ratio = 0.7, 95% CI = 0.58-0.87; n = 10). However, the prevalence of HBV was not significantly different by age, religion, marital status, or tribe. The prevalence of HBV was not significantly different among pregnant women with previous surgery, blood transfusion, multiple lifetime sex partners, tribal marks, tattoos, scarification, or sexually transmitted infections, compared with those without these risk factors. From a total sample size of 128 (n = 7), the pooled prevalence of HBeAg among HBV-infected pregnant women was 14.59% (95% CI = 4.58-27.99%; I2 = 65.5%, p = 0.01). Subgroup analyses of HBV infection by study region and screening method, and meta-regression analysis of the study year, sample size, and quality rating were not statistically significant.ConclusionsThere is an intermediate endemicity of HBV infection among pregnant women in Nigeria. Interventions, such as routine antenatal HBV screening, antiviral prophylaxis for eligible pregnant women, and infant HBV vaccination should be scaled up for the prevention of perinatal transmission of HBV infection in Nigeria.

Project description:IntroductionHepatitis B virus (HBV) is one of the major public health problems globally and needs an urgent response. It is one of the most responsible causes of mortality among the five hepatitis viruses, and it affects almost every class of individuals. Different studies were conducted on the prevalence of HBV among pregnant women in East African countries, but none of them showed the pooled prevalence of HBV among the pregnant women. Thus, the main objective of this study was to determine the pooled prevalence and its determinants among pregnant women in East Africa.MethodsWe searched studies using PubMed, Scopus, Embase, ScienceDirect, Google Scholar and grey literature that were published between January 01/2020 to January 30/2024. The studies were assessed using the Newcastle Ottawa Scale (NOS) quality assessment scale. The random-effect (DerSimonian) model was used to determine the pooled prevalence and associated factors of HBV among pregnant women. Heterogeneity were assessed by I2 statistic, sub-group analysis, and sensitivity analysis. Publication bias was assessed by Egger test, and the analysis was done using STATA version 17.ResultA total of 45 studies with 35639 pregnant women were included in this systematic review and meta-analysis. The overall pooled prevalence of HBV among pregnant women in East Africa was 6.0% (95% CI: 6.0%-7.0%, I2 = 89.7%). The highest prevalence of 8% ((95% CI: 6%, 10%), I2 = 91.08%) was seen in 2021, and the lowest prevalence 5% ((95% CI: 4%, 6%) I2 = 52.52%) was observed in 2022. A pooled meta-analysis showed that history of surgical procedure (OR = 2.14 (95% CI: 1.27, 3.61)), having multiple sexual partners (OR = 3.87 (95% CI: 2.52, 5.95), history of body tattooing (OR = 2.55 (95% CI: 1.62, 4.01)), history of tooth extraction (OR = 2.09 (95% CI: 1.29, 3.39)), abortion history(OR = 2.20(95% CI: 1.38, 3.50)), history of sharing sharp material (OR = 1.88 (95% CI: 1.07, 3.31)), blood transfusion (OR = 2.41 (95% CI: 1.62, 3.57)), family history of HBV (OR = 4.87 (95% CI: 2.95, 8.05)) and history needle injury (OR = 2.62 (95% CI: 1.20, 5.72)) were significant risk factors associated with HBV infection among pregnant women.ConclusionsThe pooled prevalence of HBV infection among pregnant women in East Africa was an intermediate level and different across countries ranging from 1.5% to 22.2%. The result of this pooled prevalence was an indication of the need for screening, prevention, and control of HBV infection among pregnant women in the region. Therefore, early identification of risk factors, awareness creation on the mode of transmission HBV and implementation of preventive measures are essential in reducing the burden of HBV infection among pregnant women.

Project description:BackgroundIn Ethiopia limited information is available regarding the prevalence and predictors of anemia in pregnancy. This systematic review and meta-analysis estimated the pooled prevalence of anemia among pregnant women in Ethiopia and also identified its predictors.Materials and methodsThe published primary studies were searched in the following electronic databases; PubMed/Medline, Google scholars, AJOL, and EMBASE. All primary studies published from 01/01/2010 to 30/05/2020 and written in English language were included without restriction on study setting and design. Critical appraisal of all available articles was done and extracted data was analyzed using STATA software version 14. The pooled prevalence of anemia was presented using a forest plot. The I2 statistical test for heterogeneity, and the Egger's and Begg's tests for publication bias were used. The relative risk was used to assess the association of predictor variables with anemia.ResultAfter screening 274 articles, sixty studies were included in the analysis. The pooled prevalence of anemia among pregnant women was 26.4(95% CI: 23.1, 29.6). Sub-group analysis showed higher pooled prevalence from community-based studies than institutional-based studies. Factors that were protective against maternal anemia included urban residence, formal education and smaller family size. Short birth interval and not having antenatal care (ANC) are associated with a higher risk of maternal anemia. Women with low dietary diversity [RR: 2.61(95% CI, 1.85, 3.68)], mid-upper arm circumference (MUAC) less than 23 cm [RR: 2.35(95% CI, 1.53, 3.68)] and those not taking iron-folic acid [RR: 1.53(95% CI: 1.30, 1.81)] also had a higher risk of anemia.ConclusionAlmost one in four pregnant women in Ethiopia had anemia. Being literate, living in urban areas with small family size and adequate birth spacing, as well as good dietary diversity are associated with a lower risk of anemia in pregnancy.Registration number(ID: CRD42020211054).

Project description:BACKGROUND:Anemia during pregnancy is one of the most common indirect obstetric cause of maternal mortality in developing countries. It is responsible for poor maternal and fetal outcomes. A limited number of studies were conducted on anemia during pregnancy in Ethiopia, and they present inconsistent findings. Therefore, this review was undertaken to summarize the findings conducted in several parts of the country and present the national level of anemia among pregnant women in Ethiopia. METHODS:Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline was followed for this systematic review and meta-analysis. The databases used were; PUBMED, Cochrane Library, Google Scholar, CINAHL, and African Journals Online. Search terms used were; anemia, pregnancy related anemia and Ethiopia. Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI) was used for critical appraisal of studies. The meta-analysis was conducted using STATA 14 software. The pooled Meta logistic regression was computed to present the pooled prevalence and relative risks (RRs) of the determinate factors with 95% confidence interval (CI). RESULTS:Twenty studies were included in the meta-analysis with a total of 10, 281 pregnant women. The pooled prevalence of anemia among pregnant women in Ethiopia was 31.66% (95% CI (26.20, 37.11)). Based on the pooled prevalence of the subgroup analysis result, the lowest prevalence of anemia among pregnant women was observed in Amhara region, 15.89% (95% CI (8.82, 22.96)) and the highest prevalence was in Somali region, 56.80% (95% CI (52.76, 60.84)). Primigravid (RR: 0.61 (95% CI: 0.53, 0.71)) and urban women (RR: 0.73 (95% CI: 0.60, 0.88)) were less likely to develop anemia. On the other hand, mothers with short pregnancy interval (RR: 2.14 (95% CI: 1.67, 2.74)) and malaria infection during pregnancy (RR: 1.94 (95% CI: 1.33, 2.82)) had higher risk to develop anemia. CONCLUSIONS:Almost one-third of pregnant women in Ethiopia were anemic. Statistically significant association was observed between anemia during pregnancy and residence, gravidity, pregnancy interval, and malaria infection during pregnancy. Regions with higher anemia prevalence among pregnant women should be given due emphasis. The concerned body should intervene on the identified factors to reduce the high prevalence of anemia among pregnant women.
