Hepatitis B prevalence association with sexually transmitted infections: a systematic review and meta-analysis.
Ontology highlight
ABSTRACT: Methods
We conducted a systematic review and meta-analysis. PubMed, Embase, and Web of Science from 1982 to 2018 were searched using medical subject headings (MeSH) terms for HBV, STIs and epidemiology. We included studies conducted in Organisation for Economic Cooperation and Development countries or Latin America that permit the calculation of prevalence ratios (PRs) for HBV and STIs and extracted PRs and counts by HBV and STI status.Results
Of 3144 identified studies, 43 met inclusion requirements, yielding 72 PRs. We stratified outcomes by HBV sero-markers [surface antigen (HBsAg), hepatitis B core antibody (anti-HBc), combined], STI pathogen (syphilis, gonorrhoea/chlamydia, unspecified), and STI history (current, past) resulting in 18 potential outcome groups, for which results were available for 14. For the four outcome groups related to HBsAg, PR point estimates ranged from 1.65 to 6.76. For the five outcome groups related to anti-HBc, PRs ranged from 1.30 to 1.82; and for the five outcome groups related to combined HBV markers, PRs ranged from 1.15 to 1.89). The median HBsAg prevalence among people with a current or past STI was 4.17; not all studies reported HBsAg. Study settings and populations varied.Conclusion
This review found evidence of association between HBV infection and current or past STIs.

Project description:BackgroundThe potential for an expanded HIV epidemic in Papua New Guinea (PNG) demands an effective, evidence-based and locally-appropriate national response. As sexually transmitted infections (STIs) may be important co-factors in HIV transmission nationally, it is timely to conduct a systematic review of STI prevalences to inform national policy on sexual health and HIV/STI prevention.Methodology/principal findingsWe undertook a systematic review and meta-analysis of HIV and STI prevalences in PNG, reported in peer-reviewed and non-peer-reviewed publications for the period 1950-2010. Prevalence estimates were stratified by study site (community or clinic-based), geographic area and socio-demographic characteristics. The search strategy identified 105 reports, of which 25 studies (10 community-based; 10 clinic-based; and 5 among self-identified female sex workers) reported STI prevalences and were included in the systematic review. High prevalences of chlamydia, gonorrhoea, syphilis and trichomonas were reported in all settings, particularly among female sex workers, where pooled estimates of 26.1%, 33.6%, 33.1% and 39.3% respectively were observed. Pooled HIV prevalence in community-based studies was 1.8% (95% CI:1.2-2.4) in men; 2.6% (95% CI:1.7-3.5) in women; and 11.8% (95% CI:5.8-17.7) among female sex workers.Conclusions/significanceThe epidemiology of STIs and HIV in PNG shows considerable heterogeneity by geographical setting and sexual risk group. Prevalences from community-based studies in PNG were higher than in many other countries in the Asia-Pacific. A renewed focus on national STI/HIV surveillance priorities and systems for routine and periodic data collection will be essential to building effective culturally-relevant behavioural and biomedical STI/HIV prevention programs in PNG.

Project description:BACKGROUND: Rapid economic development in urban China has led to a mass migration of surplus rural residents into urban areas for better employment opportunities. This study aims to identify prevalence levels and risks of sexually transmitted infections (STIs) and hepatitis among the rural-to-urban migrant population in China. METHODS: Chinese and English literature databases were searched for studies reporting prevalence of HIV, STIs and viral hepatitis among rural-to-urban migrants in China between 1990 and 2013. The estimates were summarised through a systematic review and meta-analysis. The risks of infection were compared between migrants and the general Chinese population. RESULTS: We identified a total of 411 eligible studies. The prevalence of HIV, syphilis, gonorrhea, genital warts and HCV among migrants were 0.23% (0.20-0.27%), 0.69% (0.57-0.84%), 2.18% (1.30-3.64%), 1.54% (0.70-3.36%) and 0.45% (0.31-3.65%), representing 4.0 (3.1-5.2), 1.9 (1.1-3.0), 13.6 (5.8-32.1), 38.5 (15.7-94.5) and 3.8 (1.9-7.3) higher odds of infection than among the general population. Construction workers, long-distance truck drivers and migrant women through marriage were migrant subgroups that were highly susceptible to STIs and hepatitis. HIV prevalence among migrant pregnant women (0.10%, 0.02-0.49%) was significantly higher than that of pregnant women in the general Chinese population (OR = 7.7, 3.4-17.4). However, no significant differences were observed in STIs and hepatitis between overall female sex workers (FSWs), men who have sex with men (MSM) and drug users (DUs), and the corresponding subgroups with a migratory background. CONCLUSIONS: Rural-to-urban migrants have a higher risk of STIs and hepatitis than the general Chinese population, but a migratory background does not increase the infection risks of STIs and hepatitis in FSWs, MSM and DUs.

Project description:BackgroundSexually 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.ObjectiveTo assess the prevalence of delayed treatment for STIs and its determinants in sub-Saharan African countries.MethodArticles 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.ResultsAbout 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.ConclusionThe 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:There are 150 million women worldwide using combined or progestogen-only hormonal contraceptive methods who may be at risk of sexually transmitted infections (STIs). Previous systematic reviews that have sought to establish whether there is an aetiological association between hormonal contraceptive methods/use and STIs have been limited in their methods and have mixed findings. We sought to update these reviews using appropriate control groups. We undertook a systematic review following the PRISMA guidelines and meta-analysis to examine the association between the use of all hormonal contraceptive methods and the acquisition of STIs (Neisseria gonorrhoeae, syphilis/Treponema pallidum, Chlamydia trachomatis, herpes simplex virus, and Trichomonas vaginalis) and/or bacterial vaginosis in literature published between 2005 and 2020. We analysed the effect of hormonal contraceptive methods/use separately on the prevalence, incidence and recurrence of STIs. A total of 37 studies were included in this review that reported 61 associations, in which 27 prevalence, eight incidence and two recurrence studies provided 43, 16, and two associations, respectively. We observed a positive association between hormonal contraceptive methods/use and the risk of chlamydia and herpes but a negative association for trichomoniasis and vaginosis. A negative but statistically insignificant association was observed between hormonal contraceptive methods/use and gonorrhoea. Hormonal contraceptive methods/use influences a woman's risk of STIs/ bacterial vaginosis, but the risk may differ depending on the type of STI. These findings should be contextualized carefully, particularly when formulating practice guidelines and policy, as the effects of hormonal contraceptive methods/use on the risk of STIs varied in direction when analysed separately by STI.

Project description:Soil transmitted helminth (STH) infections still remain a notable health problem in resource-limited countries due to difficulties in the implementation of control measures. In Nigeria for instance, despite several community-based and provincial reports, national data on prevalence, burdens and risk zones (RZs) for STH infections are lacking.The present study employed the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) to determine the prevalence, distribution and RZs for STH infections among Nigerian children through a meta-analysis of data published between 1980 and 2015. Pooled prevalence estimate (PPE) was determined by the random-effects model while heterogeneity was evaluated using the Cochran's Q-test.A total of 18?901 of the 34?518 Nigerian children aged 0-17 years examined across 19 Nigerian states during the period under review were infected with one or more species of STHs. The overall PPE for STH infections was 54.8% (95% CI: 54.2-55.3). PPEs for sub-groups ranged between 13.2% (95% CI: 11.5-15.1) and 80.9% (95% CI: 80.0-81.7). Highest PPEs for STH infections were observed among children within community settings (59.0%, 95% CI: 57.7-60.4) and school-aged children (54.9%, 95% CI: 54.3-55.5). Ascaris lumbricoides was the most prevalent species (44.6%, 95% CI: 44.0-45.2). Over 36% (15/41) of the studies were published from south-western Nigeria. South-western region was the only high risk zone (HRZ) for STH infections while the rest of the regions were low risk zones (LRZs).STH infections involving Ascaris lumbricoides, Strongyloides stercoralis, Trichuris trichiura and hookworms are highly prevalent across Nigeria. Strategic use of anthelmintics, health education and adequate sanitation, taking into account this epidemiologic information will help in the control of these infections in Nigeria.

Project description:BackgroundThe 1980's economic boom has been associated with a rapid expansion of China's sex industry over the past three decades. Consequently, the spread of sexually transmitted infections (STIs) and hepatitis infections among female sex workers (FSW) has become an important public health issue in China. This study identifies prevalence and risks of hepatitis and STIs in Chinese FSWs.MethodFour electronic databases were searched for Chinese and English language peer-reviewed studies conducted between 01/2000-12/2011 that reported prevalence of hepatitis and STIs (excluding HIV) among Chinese FSW. Following the PRISMA guidelines, meta-analysis was used to estimate pooled prevalence and 95% confidence intervals for each infection.ResultThree hundred and thirty nine articles (34 in English and 305 in Chinese) investigating 603,647 FSWs in 29 Chinese provinces were included in this review. Over the period 2000-2011, the seroprevalence of active hepatitis B and hepatitis C among FSW were 10.7% (7.3-15.5%) and 1.0% (0.7-1.3%), respectively. The most prevalent STI was human papillomavirus (HPV, 27.0% [10.1-55.1%]), followed by herpes simplex virus-2 (HSV-2, 15.8% [11.7-20.9%]), chlamydia (13.7% [12.1-15.4%]), gonorrhoea (6.1% [5.3-7.0%]), syphilis (5.2% [4.8-5.7%]), genital warts (3.3% [2.5-4.2%]) and Trichomonas vaginitis (2.1% [1.5-24.2%]). Disease burden of both hepatitis and STI among FSW were concentrated in South Central and Southwest China. In particular, chlamydia and syphilis demonstrated a significant declining trend during the studied period (P?<?0.05). Compared with the general Chinese population, FSW had significantly higher prevalence of all STIs except Trichomonas vaginitis. Further, compared to the general FSW population, HIV-positive FSW had significantly higher prevalence of syphilis, chlamydia, HSV-2 and Trichomonas vaginitis.ConclusionPrevalence of hepatitis and STIs remained high and mostly stable among Chinese FSW over the period of 2000-2011. Targeted STI and hepatitis surveillance and interventions should be strengthened among Chinese FSWs, especially those who are HIV-positive.

Project description:BackgroundFemale sex workers have been the target of numerous sexually transmitted infection (STI) prevention strategies in China, but their male clients have attracted considerably less public health attention and resources. We sought to systematically assess the prevalence of HIV, syphilis, gonorrhea, and chlamydia among heterosexual male clients of female sex workers in China.Methods/principal findingsOriginal research manuscripts were identified by searching Chinese and English language databases, and 37 studies analyzing 26,552 male clients were included in the review. Client STI prevalence across studies was heterogeneous. Pooled prevalence estimates and 95% confidence intervals were 0.68% (0.36-1.28%) for HIV, 2.91% (2.17-3.89%) for syphilis, 2.16% (1.46-3.17%) for gonorrhea, and 8.01% (4.94-12.72%) for chlamydia.Conclusions/significanceThe pooled prevalence estimates of HIV, syphilis, gonorrhea, and chlamydia among clients in this review exceed the prevalences previously reported among population-representative samples and low-risk groups in China. However, heterogeneity across studies and sampling limitations prevent definitive conclusions about how the prevalence of STIs in this population compares to the general population. These findings suggest a need for greater attention to clients' sexual risk and disease prevalence in China's STI research agenda in order to inform effective prevention policies.

Project description:ObjectivesAre behavioural interventions effective in reducing the rate of sexually transmitted infections (STIs) among genitourinary medicine (GUM) clinic patients?DesignSystematic review and meta-analysis of published articles.Data sourcesMedline, CINAHL, Embase, PsychINFO, Applied Social Sciences Index and Abstracts, Cochrane Library Controlled Clinical Trials Register, National Research Register (1966 to January 2004).Review methodsRandomised controlled trials of behavioural interventions in sexual health clinic patients were included if they reported change to STI rates or self reported sexual behaviour. Trial quality was assessed using the Jadad score and results pooled using random effects meta-analyses where outcomes were consistent across studies.Results14 trials were included; 12 based in the United States. Experimental interventions were heterogeneous and most control interventions were more structured than typical UK care. Eight trials reported data on laboratory confirmed infections, of which four observed a greater reduction in their intervention groups (in two cases this result was statistically significant, p < 0.05). Seven trials reported consistent condom use, of which six observed a greater increase among their intervention subjects. Results for other measures of sexual behaviour were inconsistent. Success in reducing STIs was related to trial quality, use of social cognition models, and formative research in the target population. However, effectiveness was not related to intervention format or length.ConclusionsWhile results were heterogeneous, several trials observed reductions in STI rates. The most effective interventions were developed through extensive formative research. These findings should encourage further research in the United Kingdom where new approaches to preventing STIs are urgently required.

Project description:BACKGROUND:Rates of STIs continue to rise worldwide, and novel evidence-based interventions such as text messaging aimed at improving client services are needed. We conducted a meta-analysis to evaluate text messaging to support STI/HIV prevention and treatment interventions. METHODS:We included articles that reported findings from randomized controlled trials (RTCs) involving adults and youth who were at risk of acquiring (or who currently had) a STI and/or HIV, a text message and comparator intervention, and reported provided outcome data on adherence to STI/HIV treatments. Articles were excluded if they were not published in English. We only included studies that have full-text publications so certainty and risk of bias assessments could be performed. Eight databases were searched to retrieve articles published between 1996 and March 2017. The Cochrane risk of bias tool was used and certainty of the evidence was assessed using GRADE. Effect estimates were pooled using a random effects model. RESULTS:A total of 35 RCTs were found, 6 of which were considered at low risk of bias. Eight studies found an increased association using text messaging in appointments attended compared to standard care (OR 1.64, 95% CI 1.28 to 2.10). Participants receiving text messages had an increase in HIV testing compared to standard care (n?=?6; OR 1.73, 95% CI 1.39 to 2.15). Ten text messaging RCTs measuring adherence using micro-electro-mechanical systems (MEMS) pill counts has a non-significant association (OR 1.17, 95% CI 0.95-1.45) while five studies measuring adherence by self-report was found to be significant (OR 1.64, 95% CI 1.28-2.11). CONCLUSIONS:The effectiveness of text message interventions is equivocal. While text messaging has the potential to enhance the delivery of STI/HIV interventions, program planners are encouraged to evaluate any SMS intervention to ensure it is achieving the desired result.

Project description:Sexually transmitted infections (STIs) are common among adolescents. According to the Health Belief Model, cues to action influence preventive behaviors. Cues to action can include health experiences such as being diagnosed with an STI. The impact of a history of STIs on subsequent condom use among adolescents remains largely unexamined, despite high rates of recurrence and their health impacts. This project aimed to systematically review the literature on the association between curable STIs and subsequent condom use among adolescents. The systematic review, reported following PRISMA guidelines, was conducted using the Joanna Briggs Institute method. Eligible studies, in the form of cohort studies, case-control studies, or cross-sectional studies, targeted adolescents aged 10 to 24, with or without a history of curable STIs; the outcome was subsequent condom use. MEDLINE (Ovid), Embase (Elsevier), and Web of Science were searched from January 2012 to December 2022 with the assistance of an information specialist. Two reviewers independently selected articles and extracted data. Risk of bias analysis was performed using ROBINS-E. The review explores results, with tables, based on population characteristics, exposure, and outcome, and addresses the influence of gender, ethnicity, and age. Of 3088 articles identified, seven studies were retained. Almost all the studies focused on African-American, Nigerian, or Rwandan adolescents, and several included only girls. Among girls, a history of STI increased subsequent condom use in combination with other contraceptive methods (n = 4). Among boys and older adolescents of both genders, a history of STI was associated with a decrease in condom use (n = 3). No study distinguished between different STIs. While all the studies (n = 7) presented a high risk of bias, six did not present a threat to conclusion validity. All the studies indicated that a history of STI could influence subsequent protective behaviors, possibly by acting as a cue to action, as posited by the Health Belief Model. This information enhances our understanding of factors leading to the adoption of preventive health measures among adolescents and could apply to other infectious experiences.Registration The protocol is registered in PROSPERO (CRD42023397443).
