Prevalence of delayed treatment for sexually transmitted infections and its determinants in sub-Saharan Africa. A systematic review and meta-analysis.

ABSTRACT:

Background

Sexually transmitted infection is a common public health issue, and it is characteristically transmitted through sexual intercourse. Around the globe, particularly in less developed countries, delayed treatment of this infection could lead to a health and economic burden. Even though the health and economic burden of sexually transmitted infections is high, studies to identify the pooled proportion and the possible factor of delayed treatment seeking are rare in sub-Saharan African countries.

Objective

To assess the prevalence of delayed treatment for STIs and its determinants in sub-Saharan African countries.

Method

Articles searched on search engines like Medline via PubMed, HINARI, Embase, Scopus, Cochrane Library, Science Direct, and websites like Google Scholar. The searching mechanism was using keywords and medical subject heading terms by combining the key terms of the title. To assure the quality of the included articles, Joana Brigg's Institute critical appraisal checklist was used. To assess the heterogeneity of the studies, a sensitivity analysis was conducted. The PRISMA checklist was used, and to estimate the pooled odds ratio, a random effect model was considered. The pooled odds ratio of 95% CL was used to identify the factors.

Results

About 13 studies with 46,722 participants were incorporated. Despite considerable heterogeneity, the pooled prevalence of delayed treatment for STI in Sub-Saharan Africa was 47% (95% CI: 42%-51%, I2 = 98.42, p<0.001). Geographically, the higher pooled prevalence of delayed treatment for STI was in the eastern part of Africa (50%) (95% CI: 41%-59%, I2 = 98.42, p<0.001). Rural residence (OR = 1.44, 95% CI: 1.03-2.01, I2 = 39.3%, p-value = 0.19), poor knowledge about STI (OR = 1.49, 95% CI: 1.04-2.13, I2 = 93.1%, p-value = <0.001), perceived as STIs not serious (OR = 2.1, 95% CI: 1.86-2.36, I2 = 73.7%, p-value = 0.022), misconception for STD cause (OR = 1.39, 95% CI: 1.12-1.72), no education (OR = 4.1, 95% CI: 3.4-5.1), primary education (OR = 3.17, 95% CI: 2.23-4.2), and secondary education (OR = 1.57, 95% CI: 1.1-2.76) as compared to secondary and above education were factors associated with delayed treatment for STIs.

Conclusion

The pooled prevalence of delayed treatment for STIs in Sub-Saharan African countries was high. Poor knowledge, attitude, and educational status affect the treatment delay for STIs. Thus, improving knowledge, educational status, and attitude are highly recommended to reduce the delayed treatment of STIs.

Project description:ImportanceExtreme precipitation, including heavy rains and flooding, is associated with poor health outcomes mediated in part by decreases in income and food production. However, the association between heavy rains and HIV burden is unknown.ObjectiveTo investigate the association between heavy rainfall, HIV prevalence, and HIV transmission risk over a 12-year span in sub-Saharan Africa.Design, setting, and participantsA cross-sectional population-based study, using data collected from the 2005-2017 Demographic and Health Surveys, was conducted in 21 countries in sub-Saharan Africa and analyzed from July 29, 2021, to June 14, 2022.ExposuresHeavy rainfall was defined based on the extent to which annual rainfall deviated from the historical average (standardized precipitation index ≥1.5) at the enumeration area level.Main outcomes and measuresHIV, self-reported sexually transmitted infections (STIs), and number of sexual partners.ResultsThe study included 288 333 participants aged 15 to 59 years; 172 344 were women (59.8%), and 183 378 were married (63.6%). Mean (SD) age was 31.9 (10.0) years. Overall, 42.4% of participants were exposed to at least 1 year of heavy rainfall in the past 10 years. Each year of heavy rainfall was associated with 1.14 (95% CI, 1.11-1.18) times the odds of HIV infection and 1.11 (95% CI, 1.07-1.15) times the odds of an STI in the past 12 months. There was also an association between heavy rainfall and the reported number of sexual partners (incident rate ratio, 1.12; 95% CI, 1.10-1.15). The odds were greater for the association between heavy rainfall and HIV prevalence and STIs among participants aged older than 20 years and participants in rural areas.Conclusions and relevanceThe findings of this study suggest that heavy rainfall was associated with a higher HIV burden in sub-Saharan Africa. The association between heavy rainfall and STIs and number of sexual partners suggests that an increase in the risk of sexual transmission is a plausible mechanism for the observed findings around HIV prevalence. Heavy rainfall could also worsen food insecurity, increasing the risk of transactional sex, or cause damage to public health infrastructure, reducing access to STI education, HIV testing, and treatment.

Project description:BackgroundEstimates of sexually transmitted infection (STI) prevalence are essential for efforts to prevent and control STIs. Few large STI prevalence studies exist, especially for low- and middle-income countries (LMICs). Our primary objective was to estimate the prevalence of chlamydia, gonorrhea, trichomoniasis, syphilis, herpes simplex virus type 2 (HSV-2), and bacterial vaginosis (BV) among women in sub-Saharan Africa by age, region, and population type.Methods and findingsWe analyzed individual-level data from 18 HIV prevention studies (cohort studies and randomized controlled trials; conducted during 1993-2011), representing >37,000 women, that tested participants for ≥1 selected STIs or BV at baseline. We used a 2-stage meta-analysis to combine data. After calculating the proportion of participants with each infection and standard error by study, we used a random-effects model to obtain a summary mean prevalence of each infection and 95% confidence interval (CI) across ages, regions, and population types. Despite substantial study heterogeneity for some STIs/populations, several patterns emerged. Across the three primary region/population groups (South Africa community-based, Southern/Eastern Africa community-based, and Eastern Africa higher-risk), prevalence was higher among 15-24-year-old than 25-49-year-old women for all STIs except HSV-2. In general, higher-risk populations had greater prevalence of gonorrhea and syphilis than clinic/community-based populations. For chlamydia, prevalence among 15-24-year-olds was 10.3% (95% CI: 7.4%, 14.1%; I2 = 75.7%) among women specifically recruited from higher-risk settings for HIV in Eastern Africa and was 15.1% (95% CI: 12.7%, 17.8%; I2 = 82.3%) in South African clinic/community-based populations. Among clinic/community-based populations, prevalence was generally greater in South Africa than in Southern/Eastern Africa for most STIs; for gonorrhea, prevalence among 15-24-year-olds was 4.6% (95% CI: 3.3%, 6.4%; I2 = 82.8%) in South Africa and was 1.7% (95% CI: 1.2%, 2.6%; I2 = 55.2%) in Southern/Eastern Africa. Across the three primary region/population groups, HSV-2 and BV prevalence was high among 25-49-year-olds (ranging from 70% to 83% and 33% to 44%, respectively). The main study limitation is that the data are not from random samples of the target populations.ConclusionsCombining data from 18 HIV prevention studies, our findings highlight important features of STI/BV epidemiology among sub-Saharan African women. This methodology can be used where routine STI surveillance is limited and offers a new approach to obtaining critical information on STI and BV prevalence in LMICs.

Project description:IntroductionMalaria infection and curable sexually transmitted infections and reproductive tract infections (STIs/RTIs) adversely impact pregnancy outcomes. In sub-Saharan Africa, the prevalence of malaria and curable STIs/RTIs is high and, where coinfection is common, combination interventions may be needed to improve pregnancy outcomes. The aim of this systematic review is to estimate the prevalence of malaria and curable STI/RTI coinfection during pregnancy, risk factors for coinfection and prevalence of associated adverse pregnancy outcomes.Methods and analysisWe will use three electronic databases, PubMed, EMBASE and Malaria in Pregnancy Library to identify studies involving pregnant women attending routine antenatal care facilities in sub-Saharan Africa and reporting malaria and curable STI/RTI test results, published in any language since 2000. We will search databases in the second quarter of 2023 and repeat the search before completion of our analyses. The first two authors will screen titles and abstracts, selecting studies that meet inclusion criteria and qualify for full-text screening. If agreement on inclusion/exclusion cannot be reached, the last author will serve as arbiter. We will extract data from eligible publications for a study-level meta-analysis. We will contact research groups of included studies and request individual participant data for meta-analysis. The first two authors will conduct a quality appraisal of included studies using the GRADE system. The last author will adjudicate if the first two authors do not agree on any appraisals. We will conduct sensitivity analyses to test the robustness of effect estimates over time (by decade and half-decade periods), geography (East/Southern Africa vs West/Central Africa), gravidity (primigravidae, secundigravidae, multigravidae), treatment type and dosing frequency, and malaria transmission intensity.Ethics and disseminationWe obtained ethics approval from the London School of Hygiene & Tropical Medicine (LSHTM Ethics Ref: 26167). Results of this study will be disseminated via peer-reviewed publication and presentation at scientific conferences.Prospero registration numberCRD42021224294.

Project description:BackgroundDriven by global targets to eliminate soil-transmitted helminths as a public health problem, governments have rapidly rolled out control programmes using school and community-based platforms. To justify and target ongoing investment, quantification of impact and identification of remaining high-risk areas are needed. We aimed to assess regional progress towards these targets.MethodsWe did a continental-scale ecological analysis using a Bayesian space-time hierarchical model to estimate the effects of known environmental, socioeconomic, and control-related factors on the prevalence of soil-transmitted helminths, and we mapped the probability that implementation units had achieved moderate-to-heavy intensity infection prevalence of less than 2% among children aged 5-14 years between Jan 1, 2000, and Dec 31, 2018.FindingsWe incorporated data from 26 304 georeferenced surveys, spanning 3096 (60%) of the 5183 programmatic implementation units. Our findings suggest a reduction in the prevalence of soil-transmitted helminths in children aged 5-14 years in sub-Saharan Africa, from 44% in 2000 to 13% in 2018, driven by sustained delivery of preventive chemotherapy, improved sanitation, and economic development. Nevertheless, 1301 (25%) of 5183 implementation units still had an estimated prevalence of moderate-to-heavy intensity infection exceeding the 2% target threshold in 2018, largely concentrated in nine countries (in 1026 [79%] of 1301 implementation units): Nigeria, Democratic Republic of the Congo, Ethiopia, Cameroon, Angola, Mozambique, Madagascar, Equatorial Guinea, and Gabon.InterpretationOur estimates highlight the areas to target and strengthen interventions, and the areas where data gaps remain. If elimination of soil-transmitted helminths as a public health problem is to be achieved in sub-Saharan Africa by 2030, continued investment in treatment and prevention activities are essential to ensure that no areas are left behind.FundingBill & Melinda Gates Foundation.

Project description:BackgroundRecent outbreaks of Ebola virus disease (EVD) and Marburg virus disease (MVD) in sub-Saharan Africa illustrate the need to better understand animal reservoirs, burden of disease, and human transmission of filoviruses. This protocol outlines a systematic literature review to assess the prevalence of filoviruses that infect humans in sub-Saharan Africa. A secondary aim is to qualitatively describe and evaluate the assays used to assess prevalence.MethodsThe data sources for this systematic review include PubMed, Embase, and Web of Science. Titles, abstracts, and full texts will be reviewed for inclusion by a primary reviewer and then by a team of secondary reviewers, and data will be extracted using a pre-specified and piloted data extraction form. The review will include human cross-sectional studies, cohort studies, and randomized controlled trials conducted in sub-Saharan Africa up until March 13, 2024 that have been published in peer-reviewed scientific journals, with no language restrictions. Prevalence will be stratified by pathogen, population, assay, and sampling methodology and presented in forest plots with estimated prevalence and 95% confidence intervals. If there are enough studies within a stratum, I2 statistics will be calculated (using R statistical software), and data will be pooled if heterogeneity is low. In addition, assays used to detect infection will be evaluated. All studies included in the review will be assessed for quality and risk of bias using the JBI Prevalence Critical Appraisal Tool and for certainty using the GRADE certainty ratings.DiscussionAccurately measuring the rate of exposure to filoviruses infecting humans in sub-Saharan Africa using prevalence provides an essential understanding of natural history, transmission, and the role of subclinical infection. This systematic review will identify research gaps and provide directions for future research seeking to improve our understanding of filovirus infections. Understanding the natural history, transmission, and the role of subclinical infection is critical for predicting the impact of an intervention on disease burden.Systematic review registrationIn accordance with the guidelines outlined in the PRISMA-P methodology, this protocol was registered with PROSPERO on April 7, 2023 (ID: CRD42023415358).

Project description:Addressing the global challenge of sexually transmitted infections (STIs) is crucial and demands immediate attention. Raising awareness, improving healthcare facilities, and implementing preventive measures are necessary to reduce the spread and mitigate their adverse effects. The treatment seeking behavior of individuals in relation to STIs is an important factor in STI prevention and control. Thus, this study aimed to identify factors associated with STI-related care-seeking behavior among sexually active men in East Africa. A weighted sample of 3,302 sexually active men from recent Demographic and Health Surveys (DHSs) in East African countries were included for analysis. To accommodate the inherent clustering in DHS data and the binary nature of the dependent variable, we applied a multi-level mixed-effect logistic regression model. The deviance value was used to select the best-fitted model. The strength of the association was estimated using an adjusted odds ratio, along with a 95% confidence interval, and statistical significance was determined at a p-value < 0.05. The pooled prevalence of STI-related care-seeking behavior among sexually active men in East Africa was 71% (95%CI: 69.76, 72.75). In the multivariable multilevel model, individuals in the age groups of 25-34 (AOR = 1.58, 95%CI: 1.22, 2.04) and 44 years and above (AOR = 1.44, 95%CI: 1.01, 2.02), those who were married (AOR = 1.62, 95%CI: 1.25, 2.11), had 1 (AOR = 1.88, 95%CI: 1.50, 2.35) and ≥2 (AOR = 2.53, 95%CI: 1.89, 3.39) sexual partners excluding their spouse, had ever been tested for HIV (AOR = 1.86, 95%CI: 1.52, 2.28), and had media exposure (AOR = 1.30, 95%CI: 1.04, 1.62) had a positive association with care-seeking behavior for STIs. Based on our findings, seven out of ten sexually active men in East Africa exhibit care-seeking behavior for STIs. It is crucial to implement policies and strategies aimed at improving the health-seeking habits of young, unmarried men. Utilizing diverse media platforms to disseminate accurate information and success stories about STI symptoms is pivotal in achieving this goal.

Project description:BackgroundAnemia is one of the world's leading cause of disability and the most serious global public health issues. This systematic review and meta-analysis was carried out very prudently in order to give up the pooled prevalence and determinants of anemia in Sub-Saharan Africa.MethodologyTo carry out this ephemeral systematic review and meta-analysis, a correlated literature review was done from various sources, PubMed Medline and Google Scholar Journals. Anemia related searching engine was used to make the study more evocative and intensive. We used modified Newcastle-Ottawa quality assessment scale for cross sectional studies to evaluate the quality of the study in relations of their inclusion. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline was tracked to conduct this study. The pooled effect size was computed using the review manager and Compressive Meta-analysis software.ResultsTwenty-fife studies, which encompassed 15,061 pregnant women, were chosen for the analysis. From those an overall prevalence of anemia in pregnancy in SSA was 35.6%. However, the result from meta-analysis showed that women who were infected with intestinal parasite were 3.59 times more likely to develop anemia compared to those who were not infected [OR:3.59, 95% CI (2.44,5.28)].The result showed that women who had no iron and folic-acid supplementation were 1.82 times more likely to develop anemia compared to those women who had iron and folic-acid supplementation {OR:1.82, 95% CI (1.22,2.70]. Women who had women were in third trimester pregnancy were 2.37 times more likely to develop anemia compared to those who were in first and second trimester [OR:2.37, 95% CI (1.78, 3.24)]. Women who had low dietary diversity score were 3.59 times more likely to develop anemia compared to those who had high dietary diversity score [OR: 3.59, 95% CI (2.44, 5.28].ConclusionsOur finding from this systematic review and meta-analysis displays the high case in prevalence of anemia among pregnant women in Sub-Saharan Africa. Predictors for this includes: intestinal parasite, iron and folic-acid supplementation, third trimester pregnancy and dietary diversified intake score were statistically correlated positively with anemia in pregnancy. These need cautious evaluation of impact of prevention effort for operational policy, programs and design nutrition intrusions for refining maternal food consumption during pregnancy. Also, dietary education intrusion requires to be prearranged to satisfy the desires of pregnant women. The finding of this work will be used as an evidences for policy makers of Africa; entirely for maternal and child health care. Lastly, we suggested further investigations to be carried out in the area of the study for more rigorous and comprehensive recommendations.
