Systematic review of interventions to prevent the spread of sexually transmitted infections, including HIV, among young people in Europe

Biological, demographic, and health factors associated with HPV infection in Ecuadorian women

Objectives

The study aims to identify the correlation between human papillomavirus (HPV) infection and sociodemographic and sexual reproductive health factors in Ecuadorian women from March to August 2019.

Methods

120 women were randomly selected from two gynecological clinics to complete a questionnaire and provide a biospecimen. PCR-Hybridization was used to genotype 37 HPV serotypes in samples obtained by endo-cervical brushing for liquid-based cytology. Sociodemographic and sexual health data were collected through a validated questionnaire during a medical consultation. Mathematical modeling of HPV infection was done using bivariate logistic regression.

Results

65.0% of the women sampled had an HPV infection; 74.3% of these women had co-infections with other HPV genotypes. Out of the women who were HPV positive, 75.6% were diagnosed with high-risk genotypes from HPV strains 18, 35, 52, and 66. Parity, immunosuppression, and use of oral contraception/intrauterine devices (IUDs) were identified as associated variables. The explanatory model had a sensitivity of 89.5% and a specificity of 73.8%.

Conclusion

The predominant strains of HPV among Ecuadorian women are diverse. The risk of HPV infection is a complex phenomenon where biological and psychosocial variables are integrated into a model. In populations with limited access to health services, low socioeconomic status, and negative sociocultural beliefs about sexually transmitted infections (STIs), surveys can be used as a pre-screening step for HPV infections. The diagnostic value of the model should be tested in multicenter studies that include women from all over the country.

A systematic review and meta-analysis of sexually transmitted infection prevention practices among Ethiopian young people

Objective

Approximately 178.5 million new cases of treatable sexually transmitted infections are thought to be diagnosed each year among young people worldwide who are between the ages of 15 and 24 years. The results regarding sexually transmitted infection prevention studies in Ethiopia are not consistent. Therefore, the objective of this systematic review and meta-analysis was to determine the pooled prevalence of sexually transmitted infection prevention methods among young people in Ethiopia.

Methods

The systematic review was developed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Between 5 January and 18 May 2022, published studies were searched using online databases such as PubMed, CINAHL, African Online Journal, and Google Scholar. The quality of the study was evaluated using the Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument. A random-effects model was used for the statistical analysis using STATA version 14 software.

Results

A total of 3331 studies were searched, and five studies with a total of 1925 participants were included in the final meta-analysis. The pooled prevalence of preventive practice toward sexually transmitted infections was 54% (95% confidence interval: 44, 64). According to a subgroup analysis based on regional state, the prevalence was highest in the southern region, at 66% (95% CI: 59, 73), and lowest in the Amhara region, at 42% (95% confidence interval: 38, 45). Institution-based studies had high heterogeneity, according to a subgroup analysis based on study setting (I ² = 95.39%, p value 0.001).

Conclusion

Almost one in every two young people is engaged in preventive practices. This is lower than the World Health Organization global health sector strategy target (70%) for sexually transmitted infections. A subgroup analysis based on regional state and study setting showed a variation in the prevalence of preventive practices and significant heterogeneity among the regions.

Overcoming barriers to HPV vaccination in rural Vermont through a multicomponent peer-based approach

Human Papillomavirus (HPV) causes almost all cervical cancers and many cancers of the anus, vagina, vulva, penis, and oropharynx. The HPV vaccine provides protection to all adolescents from a broad spectrum of cancers, yet HPV vaccination rates remain lower than those of other routine vaccines. Developing effective HPV vaccine interventions is particularly important in rural areas, whose residents have lower rates of HPV vaccination and higher cervical cancer incidence and mortality; however, interventional research in these populations is relatively limited. Furthermore, though rural areas are heterogeneous in many regards, few interventions engage stakeholders to develop community-specific solutions to overcome obstacles associated with HPV vaccination. Based on a review of existing literature, we recommend a multicomponent peer-based approach that includes school-based vaccination and awareness, parental involvement, and stakeholder engagement to increase HPV vaccination in rural areas, and we provide an example of such an intervention in rural Vermont.

Barriers and facilitators to HIV prevention interventions for reducing risky sexual behavior among youth worldwide: a systematic review

BACKGROUND

Interventions aimed at reducing risky sexual behavior are considered an important strategy for averting Human Immunodeficiency Virus (HIV) infection among youth (15-24 years) who continue to be at risk of the disease. Enhancing intervention success requires a comprehensive understanding of the barriers and facilitators to interventions targeting youth. However, there is lack of a systematic review of both quantitative and qualitative studies to comprehensively identify and synthesize barriers and facilitators to HIV prevention interventions for reducing risky sexual behavior among youth worldwide. This review aimed to identify and synthesize barriers and facilitators to HIV prevention interventions for reducing risky sexual behavior among youth globally based on original peer-reviewed studies published in the last decade.

METHODS

The Joanna Briggs Institute approach for mixed methods systematic reviews and Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were used to guide this review. Nine electronic databases, Joint United Nations Programme on HIV/AIDS and World Health Organization websites, and reference lists of included studies and systematic reviews on barriers and facilitators to HIV prevention interventions for reducing risky sexual behavior among youth were searched for eligible articles. Studies that met the inclusion criteria underwent quality appraisal and data extraction. Findings were analyzed using thematic synthesis and underpinned by Nilsen, 2015's Determinant Framework.

RESULTS

Overall 13 studies comprising of eight qualitative studies, four quantitative studies and one mixed methods study were included in the review. Several barriers and facilitators across the five Determinant Framework domains were identified. Most of the barriers fell under the characteristics of the context domain (e.g., gender-biased norms). The next important group of barriers emerged within the characteristics of the end users domain (e.g., fear of relationship breakdown). In terms of facilitators, the majority fell under the characteristics of the strategy of facilitating implementation domain (e.g., implementation of intervention with fidelity) and characteristics of the end users domain (e.g., fear of pregnancy or sexually transmitted infections). The next common set of facilitators appeared within the characteristics of the context domain (e.g., family support).

CONCLUSION

This review identified several multi-level barriers and facilitators to HIV prevention interventions for reducing risky sexual behavior among youth. Multi-level and combination approaches are needed to address these factors and enhance intervention success.

Preventive practices toward sexually transmitted infections and their determinants among young people in Ethiopia: A protocol for systematic review and meta-analysis

BACKGROUND

Globally, the estimated annual number of new cases of curable sexually transmitted infections occurring among young people aged 15-24 years is approximately 178.5 million. There are fragmented and inconsistent findings on preventive practices for sexually transmitted infections. Thus, this systematic review and meta-analysis protocol aimed to estimate the pooled prevalence of preventive practices of sexually transmitted infections and identify its determinants among young people in Ethiopia.

METHODS

The Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA) will be used to develop the review protocol. Online databases such as PubMed, CINAHL, Scopus, Google, and Google Scholar will be used to search published and unpublished studies. The Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument will be used to assess the quality of the study. Statistical heterogeneity will be checked using the Cochran Q test and I2 statistics. Subgroup analysis and meta-regression will be performed to identify the sources of heterogeneity. The statistical analysis will be performed using STATA version 14 software. A random-effects model will be performed to estimate the pooled prevalence and identify determinants of preventive practices of sexually transmitted infections.

DISCUSSION

Young people have a high unmet need for sexual and reproductive health services and poor preventive practices toward sexually transmitted infections. Although there are studies on preventive practices for sexually transmitted infections, there is no study finding on the pooled prevalence of preventive practices for sexually transmitted infections and its determinants among young people in Ethiopia. Thus, this systematic review and meta-analysis protocol will help to develop appropriate strategies.

What do young people in high-income countries want from STI testing services? A systematic review

BACKGROUND

There are upward trends of STI rates among young people in most high-income countries. We reviewed the literature to provide a summary of information to support health services with the aim of increasing testing of STIs among young people living in high-income countries.

METHODS

We conducted a systematic review (Prospero: CRD42020179720) using PubMed, Embase, PsychINFO and CINAHL. The search was performed on 10 January 2020 for studies between January 2000 and 10 January 2020. Two reviewers independently screened articles, and any discrepancies were resolved by a third reviewer. Studies were included if they were performed in high-income countries and contained data on both young people (<26 years) and STI testing preferences. Data regarding the characteristics of STI testing services that young people preferred was extracted. We categorised these characteristics using the framework of a social-ecological model.

RESULTS

We identified 1440 studies, and 63 studies were included in the final review. We found 32 studies that addressed individual factors, 62 studies that addressed service factors and 17 studies that addressed societal factors. At an individual level, we identified eight attributes including the need for improved sexual health education. At a service level, 14 attributes were identified including preferences from different subgroups of young people (such as sexual and ethnic minorities) for the types of services. At a societal level, we identified two attributes including the need to address stigma associated with STIs.

CONCLUSION

We provide an overview of the growing body of literature capturing the preferences of young people for STI testing services. To optimise the uptake of STI testing among young people, factors from all socioecological levels should be considered. In addition, understanding and accounting for distinct preferences from subgroups of young people could increase demand for STI testing services for those at greatest need.

Social Network Research contribution to evaluating process in a feasibility study of a peer-led and school-based sexual health intervention

There is growing interest in social network-based programmes to improve health, but rigorous methods using Social Network research to evaluate the process of these interventions is less well developed. Using data from the "STis And Sexual Health" (STASH) feasibility trial of a school-based, peer-led intervention on sexual health prevention, we illustrate how network data analysis results can address key components of process evaluations for complex interventions-implementation, mechanisms of impacts, and context. STASH trained students as Peer Supporters (PS) to diffuse sexual health messages though face-to-face interactions and online Facebook (FB) groups. We applied a Multilevel Exponential Random Graph modelling approach to analyse the interdependence between offline friendship relationships and online FB ties and how these different relationships align. Our results suggest that the creation of online FB communities mirrored offline adolescent groups, demonstrating fidelity of intervention delivery. Data on informal friendship networks related to student's individual characteristics (i.e., demographics, sexual health knowledge and adherence to norms, which were included for STASH), contributed to an understanding of the social relational 'building' mechanisms that sustain tie-formation. This knowledge could assist the selection of opinion leaders, improving identification of influential peers situated in optimal network positions. This work provides a novel contribution to understanding how to integrate network research with the process evaluation of a network intervention.

Prevention of Sexually Transmitted Infections and Associated Factors Among Night School Students in Bahir Dar City, Ethiopia

Background:

Sexually transmitted infections (STIs) continued to be a global public health concern, primarily among adolescents in poor socioeconomic countries. This study was aimed to assess knowledge, practice, and associated factors of night school students to prevent STIs in Bahir Dar city, Northwest Ethiopia.

Methods:

An institution-based cross-sectional study was conducted among 422 students randomly selected from night schools. Data were collected using a pretested structured questionnaire. Data were entered, cleaned, and analyzed using SPSS version 16 software. Descriptive statistics were used to describe study variables. A multivariable logistic regression analysis was used to identify factors associated with knowledge about STI and its prevention. The strengths of associations were described using odds ratio at 95% confidence interval and a P-value of less than 0.05.

Results:

A total of 420 consented students were enrolled into the study. More than half, 420 (57.9%), and three-fourths, 332 (79%), of the students were women and married. Only 24.8% and 12.4% of the students had good knowledge and practice on the prevention of STIs, respectively. Age, educational status, information access, school health education, and consistent use of condoms were factors associated with the knowledge of students about STIs. Similarly, age, sex, knowledge about STIs, and discussion with families were factors of STI prevention practice among night school students.

Conclusions:

Giving special attention to awareness creation, information access, discussion with families, and improving family/individual income is vital to prevent STIs and its impact among night school students.

Effectiveness of School-Based Teen Pregnancy Prevention Programs in the USA: a Systematic Review and Meta-Analysis

School-based programs have been a mainstay of youth pregnancy prevention efforts in the USA. We conducted a systematic review and meta-analysis to assess their effectiveness. Eligible studies evaluated the effect on pregnancy rates of programs delivered in elementary, middle, or high schools in the USA and Canada, published between January 1985 and September 2016. The primary outcome was pregnancy; secondary outcomes were delay in sexual initiation, condom use, and oral contraception use. Randomized controlled trials (RCTs) and non-RCTs with comparator groups were eligible. We developed a comprehensive search strategy, applied to major bibliographic databases, article bibliographies, gray literature, and contact with authors. We calculated risk ratios (RR) with 95% confidence intervals (CI) for each outcome and pooled data in random effects meta-analysis. We used Grading of Recommendations Assessment, Development and Evaluation (GRADE) to assess evidence quality. Ten RCTs and 11 non-RCTs conducted from 1984 to 2016 yielded 30 unique pooled comparisons for pregnancy, of which 24 were not statistically significant. Six showed statistically significant changes in pregnancy rates: two with increased risk (RR 1.30, 95% CI 1.02-1.65; and RR 1.39, 95% CI 1.10-1.75) and four with decreased risk ranging from RR 0.56, 95% CI 0.41-0.77, to RR 0.75, 95% CI 0.58-0.96. All studies were at high risk of bias, and the quality of evidence was low or very low. Identified evidence indicated no consistent difference in rates of pregnancies between intervention recipients and controls.

Behavioral Interventions to Increase Condom Use Among College Students in the United States: A Systematic Review

Background. Traditional undergraduate college students in the United States are in the age range that experiences the highest rate of sexually transmitted infections (STIs) and are vulnerable to contracting STIs. Increasing condom use among college students is a prevention strategy to reduce the spread of STIs. Aim. The purpose of this systematic review of the literature was to identify behavioral interventions that increased condom use behaviors and/or intentions among college students. Method. The Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines were followed in systematically searching, extracting, appraising, and synthesizing the evidence. A quality assessment was also conducted with the tool provided by the Effective Public Health Practice Project. Results. The initial search yielded 715 records. After critical appraisal, seven articles remained for review. Discussion. Four of the interventions were developed using the three constructs of the information, motivation, and behavioral skills model, and all four found significant increases in condom use or condom use intentions. Additionally, interventions that included modules to increase self-efficacy for condom use, taught participants where to get condoms and how to negotiate condom use with partners, or elicited positive associations (feels) toward condoms saw increased condom use or intention to use condoms.

Interventions to reduce risk for sexually transmitted infections in adolescents: A meta-analysis of trials, 2008-2016

BACKGROUND

Numerous studies have evaluated the efficacy of interventions to reduce risk for sexually transmitted infections in adolescents in recent years, but their global effects remain unknown since 2008, the last date of a comprehensive review of prior studies.

AIMS

This study aims at evaluating the efficacy of interventions to promote sexual health, reduce STIs and unplanned pregnancies targeted to adolescents available after 2008; and analyzing the moderators of their global efficacy.

METHODS

We searched electronic databases and manual searches of some journals focused on STIs in May 2016. The studies evaluated the efficacy of interventions to reduce sexual risk in adolescents (age range: 11-19) anywhere in the world. Effect size of the relevant outcomes for sexual risk was calculated for every study. Analyses incorporated random-effect assumptions for each outcome. The homogeneity in the results was examined with the I2 statistic and its associated 95% confident interval.

RESULTS

Data from 63 studies (59,795 participants) were analyzed for behavioral and non-behavioral outcomes. In the short term, interventions had a positive impact in sexual health-related knowledge (Hedges'g = 1.01), attitudes (g = 0.29), self-efficacy toward condom use (g = 0.22), intention to refuse sex (g = 0.56), condom use intention (g = 0.46), and condom use (g = 0.38). In the medium term, positive effects observed at the short-term were maintained, although effect size significantly decreased in all variables. In the long term, interventions improved condom use (g = 0.47). Moderators of the efficacy are discussed.

CONCLUSIONS

Sexual health promotion interventions are effective to promote sexual health through increasing condom use. Effects on non-behavioral variables tend to decrease over time, while condom use increased in the long-term. Interventions should focus on the long-term efficacy, especially in behavioral and biological measures.

Cross-country Association of Press Freedom and LGBT freedom with prevalence of persons living with HIV: implication for global strategy against HIV/AIDS

BACKGROUND

Human behaviors are affected by attitudes and beliefs, which in turn are shaped by higher-level values to which we have ascribed. In this study, we explore the relationship between two higher-level values, press freedom and LGBT freedom, and HIV infection with national data at the population level.

METHODS

Data were the number of persons living with HIV (PLWH, n = 35,468,911) for 148 countries during 2011-15, press freedom index (PFI) determined by the Reporters Without Borders, and LGBT freedom index (LGBT-FI) based on laws regulating same-sex relationships and expression. PLWH prevalence (1/1000), PFI and LGBT-FI were mapped first. Multiple regression was thus used to associate the logarithm of PLWH prevalence with PFI, LGBT-FI and PFI × LGBT-FI interaction, controlling for per capita GDP and weighted by population size.

RESULTS

Global prevalence of PLWH during 2011-15 was 0.51 per 1000 population. The prevalence showed a geographic pattern moving from high at the south and west ends of the world map to low at the north and east. Both PFI and LGBT-FI were positively associated with PLWH prevalence with a negative interaction between the two.

CONCLUSIONS

More people are infected with HIV in countries with higher press freedom and higher LGBT freedom. Furthermore, press freedom can attenuate the positive association between levels of LGBT freedom and risk of HIV infection. This study demonstrated the urgency for and provided data supporting further research to investigate potential cultural and socioecological mechanisms underpinning the complex relationship among press freedom, LGBT freedom and HIV infection, with data collected at the individual level.

Features of successful sexual health promotion programs for young people: findings from a review of systematic reviews

ISSUE ADDRESSED

Young people have a high burden of sexual and reproductive health (SRH) problems, and it is important to reach this group through health promotion initiatives. We conducted a systematic review of reviews to identify successful elements of health promotion programs for improving SRH of young people.

METHODS

We identified and collated systematic reviews published in 2005-2015 which focused on young people (10-24 years), reported on SRH outcomes (pregnancy, sexually transmissible infections, condoms/contraceptive use, risky sexual behaviour, sexual healthcare access or intimate partner violence), and included primary studies predominantly conducted in high-income countries. This report focuses on features of successful SRH programs identified in the interpretation and discussion of included systematic reviews.

RESULTS

We identified 66 systematic reviews, of which 37 reported on program features which were anecdotally or statistically associated with improved program effectiveness and success. Common features of effective interventions were: longer term or repeated implementation; multi-setting and multi-component; parental involvement; culturally/gender/age appropriate; and inclusion of skills-building. SO WHAT?: There is marked consistency of features improving SRH program effectiveness for young people despite the wide variation in interventions reviewed. There is a need to better implement this knowledge in future programs, and our findings provide useful guidance for optimising the design of SRH interventions for young people.

Contraceptive behavior of Portuguese higher education students

ABSTRACT Objective: To characterize the contraceptive practices of higher education students and to identify factors that contribute to the use of different contraceptive methods. Method: A cross-sectional, descriptive correlational study was carried out with a sample of 1946 students, with a mean age of 21 years (20.74±2.32), who attended courses at a University in the North of Portugal. Results: Of the factors studied, the female gender, younger ages, previous behavior of condom use, knowledge about contraception, attitude and self-efficacy for condom use were associated with safer contraceptive choices. Conclusion: Investing in sexual education for young people is an important public health strategy that can empower youth to make more appropriate choices and improve adherence to contraceptive methods, reducing the risk of unintended pregnancies and sexually transmitted diseases.

Effectiveness of a Brief Multi-Component Intervention to HIV Prevention Among Spanish Youth

The greater rate of HIV infection occurs before age 30 in Spain. Our aim was to evaluate the long-term impact of a brief HIV preventive intervention on key sexual risk behavior components in Spanish young population. Participants were 467 young people aged 18-25 years who participated in B-PAPY intervention. They were evaluated at four times: a week, a month, three months and one year after intervention. A self-administered instrument was used. It was found a significant increase from pre-test to follow-ups in HIV knowledge, HIV susceptibility perception, confidence in condom and use of condoms. There were decreases statistically significant in the perceived severity of AIDS. The HIV intervention showed effectiveness over time in the main risk variables for HIV infection. Brief multi-component HIV interventions would be a useful resource to generalize HIV prevention.

Risk factors that influence sexual and reproductive health in Portuguese university students

BACKGROUND

University students have unprotected sex and associate alcohol and/or drugs with sexual practices. These behaviours are risk factors for influencing sexual and reproductive health that can be targeted by nursing interventions.

AIM

The aim of this study was to determine the risk and protective factors influencing sexual and reproductive risk-taking behaviours in university students.

METHODS

We conducted a cross-sectional and correlational study in a sample of 1946 students. Data were collected using a self-report questionnaire on the individual, environmental, cognitive and psychosocial factors related to knowledge of sexually transmitted infections, attitude for sexual and reproductive health, subjective norms, Condom Use Self-Efficacy and Sexual Sensation Seeking scales.

RESULTS

Older male students were at higher risk for all risk behaviours studied. Students involved in committed relationships were at risk because of decreased condom use. Individuals who placed high importance on sexual sensation seeking were at increased risk. The higher the importance students placed on peers' opinion, the more protective their behaviours were.

CONCLUSION

The results of this study showed that university students are exposed to sexual risks. Individual, cognitive and psychosocial factors influence the risk-taking behaviours.

IMPLICATIONS FOR NURSING AND HEALTH POLICY

The findings of this study should be further incorporated into health care with nurses' leadership, adapting healthcare services to the specific needs of this population and promoting educational programmes.

School-based interventions for preventing HIV, sexually transmitted infections, and pregnancy in adolescents

BACKGROUND

School-based sexual and reproductive health programmes are widely accepted as an approach to reducing high-risk sexual behaviour among adolescents. Many studies and systematic reviews have concentrated on measuring effects on knowledge or self-reported behaviour rather than biological outcomes, such as pregnancy or prevalence of sexually transmitted infections (STIs).

OBJECTIVES

To evaluate the effects of school-based sexual and reproductive health programmes on sexually transmitted infections (such as HIV, herpes simplex virus, and syphilis), and pregnancy among adolescents.

SEARCH METHODS

We searched MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL) for published peer-reviewed journal articles; and ClinicalTrials.gov and the World Health Organization's (WHO) International Clinical Trials Registry Platform for prospective trials; AIDS Educaton and Global Information System (AEGIS) and National Library of Medicine (NLM) gateway for conference presentations; and the Centers for Disease Control and Prevention (CDC), UNAIDS, the WHO and the National Health Service (NHS) centre for Reviews and Dissemination (CRD) websites from 1990 to 7 April 2016. We handsearched the reference lists of all relevant papers.

SELECTION CRITERIA

We included randomized controlled trials (RCTs), both individually randomized and cluster-randomized, that evaluated school-based programmes aimed at improving the sexual and reproductive health of adolescents.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trials for inclusion, evaluated risk of bias, and extracted data. When appropriate, we obtained summary measures of treatment effect through a random-effects meta-analysis and we reported them using risk ratios (RR) with 95% confidence intervals (CIs). We assessed the certainty of the evidence using the GRADE approach.

MAIN RESULTS

We included eight cluster-RCTs that enrolled 55,157 participants. Five trials were conducted in sub-Saharan Africa (Malawi, South Africa, Tanzania, Zimbabwe, and Kenya), one in Latin America (Chile), and two in Europe (England and Scotland). Sexual and reproductive health educational programmesSix trials evaluated school-based educational interventions.In these trials, the educational programmes evaluated had no demonstrable effect on the prevalence of HIV (RR 1.03, 95% CI 0.80 to 1.32, three trials; 14,163 participants; low certainty evidence), or other STIs (herpes simplex virus prevalence: RR 1.04, 95% CI 0.94 to 1.15; three trials, 17,445 participants; moderate certainty evidence; syphilis prevalence: RR 0.81, 95% CI 0.47 to 1.39; one trial, 6977 participants; low certainty evidence). There was also no apparent effect on the number of young women who were pregnant at the end of the trial (RR 0.99, 95% CI 0.84 to 1.16; three trials, 8280 participants; moderate certainty evidence). Material or monetary incentive-based programmes to promote school attendanceTwo trials evaluated incentive-based programmes to promote school attendance.In these two trials, the incentives used had no demonstrable effect on HIV prevalence (RR 1.23, 95% CI 0.51 to 2.96; two trials, 3805 participants; low certainty evidence). Compared to controls, the prevalence of herpes simplex virus infection was lower in young women receiving a monthly cash incentive to stay in school (RR 0.30, 95% CI 0.11 to 0.85), but not in young people given free school uniforms (Data not pooled, two trials, 7229 participants; very low certainty evidence). One trial evaluated the effects on syphilis and the prevalence was too low to detect or exclude effects confidently (RR 0.41, 95% CI 0.05 to 3.27; one trial, 1291 participants; very low certainty evidence). However, the number of young women who were pregnant at the end of the trial was lower among those who received incentives (RR 0.76, 95% CI 0.58 to 0.99; two trials, 4200 participants; low certainty evidence). Combined educational and incentive-based programmesThe single trial that evaluated free school uniforms also included a trial arm in which participants received both uniforms and a programme of sexual and reproductive education. In this trial arm herpes simplex virus infection was reduced (RR 0.82, 95% CI 0.68 to 0.99; one trial, 5899 participants; low certainty evidence), predominantly in young women, but no effect was detected for HIV or pregnancy (low certainty evidence).

AUTHORS' CONCLUSIONS

There is a continued need to provide health services to adolescents that include contraceptive choices and condoms and that involve them in the design of services. Schools may be a good place in which to provide these services. There is little evidence that educational curriculum-based programmes alone are effective in improving sexual and reproductive health outcomes for adolescents. Incentive-based interventions that focus on keeping young people in secondary school may reduce adolescent pregnancy but further trials are needed to confirm this.

The readability and suitability of sexual health promotion leaflets

OBJECTIVE

To investigate the readability and suitability of sexual health promotion leaflets.

METHOD

Application of SMOG, FRY and SAM tests to assess the readability and suitability of a selection of sexual health leaflets.

RESULTS

SMOG and FRY scores illustrate an average reading level of grade 9. SAM scores indicate that 59% of leaflets are superior in design and 41% are average in design. Leaflets generally perform well in the categories of content, literacy demand, typography and layout. They perform poorly in use of graphics, learning stimulation/motivation and cultural appropriateness.

CONCLUSION

Sexual health leaflets have a reading level that is too high. Leaflets perform well on the suitability scores indicating they are reasonably suitable. There are a number of areas where sexual health leaflets could improve their design.

PRACTICE IMPLICATIONS

Numerous practical techniques are suggested for improving the readability and suitability of sexual health leaflets.

Behavioral Interventions for Preventing Sexually Transmitted Infections and Unintended Pregnancies: An Overview of Systematic Reviews

BACKGROUND

Countless sex education programs have been implemented worldwide in recent decades, but epidemiological data show no improvement in rates of sexually transmitted infections or unintended pregnancies.

OBJECTIVE

To summarize the evidence from higher-quality systematic reviews on the efficacy of behavioral interventions for the prevention of sexually transmitted infections and unintended pregnancies.

METHODS

We conducted an overview of reviews by selecting systematic reviews that met minimum quality criteria in terms of the design of the studies reviewed. We compared the results obtained when the effects of interventions were assessed on the basis of objective criteria (biological data) to those obtained when outcomes were assessed on the basis of subjective criteria (self-reports). The results of Cochrane and non-Cochrane reviews were also compared.

RESULTS

We identified 55 systematic reviews. No overall effect on the sexual behavior of program participants was observed in 72.5% of the reviews that used objective criteria and in 48.1% of the reviews based on subjective criteria. In the Cochrane reviews, no evidence of an overall effect was observed in 86% of reviews based on objective variables and in 70.5% of those based on subjective variables.

CONCLUSIONS

There is no evidence that behavioral interventions modify rates of sexually transmitted infections (including human immunodeficiency virus infections) or unintended pregnancies, particularly when effects are assessed using objective, biological data. Primary prevention strategies for sexually transmitted infections and unintended pregnancies need to be re-evaluated.

Peer mentorship program on HIV/AIDS knowledge, beliefs, and prevention attitudes among orphaned adolescents: an evidence based practice

Adolescents and young adults in sub-Saharan Africa (SSA) are particularly vulnerable to human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) infection. Adolescents orphaned as a direct result of HIV/AIDS are at an elevated risk of acquiring HIV/AIDS and other sexually transmitted infections. However, limited empirical evidence exists on HIV knowledge and prevention programs, especially those designed to address HIV information gaps among adolescents. This study evaluates the effect of a peer mentorship program provided in addition to other supportive services on HIV/AIDS knowledge, beliefs, and prevention attitudes, among school-going orphaned adolescents in southern Uganda. We utilize data from the Bridges to the Future Study, a 5-year longitudinal randomized experimental study funded by the National Institute of Child Health and Human Development. Out of the 1410 adolescents enrolled in the study (average age = 12.7 at study initiation), 855 of them participated in a nine-session, curriculum based peer mentorship program. We analyzed data collected at baseline and 12-months post intervention initiation. The results from bivariate and regression analysis indicate that, controlling for socioeconomic characteristics, adolescents who participated in a peer mentorship program were more likely than non-participants to report increased scores on HIV/AIDS knowledge(b = .86, 95%CI = .47 - 1.3, p ≤ .001); better scores on desired HIV/AIDS-related beliefs (b = .29, 95%CI = .06 - .52, p ≤ .01); and better scores on HIV/AIDS prevention attitudes (b = .76, 95%CI = .16 - 1.4, p ≤ .01). Overall, the study findings point to the potential role a of peer mentorship program in promoting the much-desired HIV/AIDS knowledge, beliefs, and prevention attitudes among orphaned adolescents. Future programs and policies that support AIDS-orphaned adolescents in sub-Saharan Africa should consider incorporating peer mentoring programs that provide correct, age, and culturally appropriate HIV information to help protect orphaned adolescents and reduce the risk of HIV infections.

Effectiveness of a prevention campaign on HIV/AIDS knowledge among adolescents in Eastern Slovakia

OBJECTIVES

The aim of this manuscript was to evaluate results of the questionnaire given to young people before and after the prevention campaign to determine whether the prevention campaign improved HIV/AIDS-related knowledge of young people.

METHODS

A total of 533 students completed the pre-test and 496 students completed the post-test. Questionnaire was used as pre/post testing tool. Construct validity and measurement scale were assessed using the factor analysis. Rasch scaling was used to establish common scale for pre/post test and to transform raw score into the interval scale. A non-parametric Mann-Whitney U test was used to compare knowledge in pre-test and post-test.

RESULTS

Students increased their knowledge of HIV/AIDS (Pearson's measure of effect size r = 0.74) and the risk of acquiring HIV infection (r = 0.68) statistically significantly (p = 0.001). Girls (risk estimation: r = 0.78, knowledge: r = 0.81) improved much more than boys (risk estimation: r = 0.57, knowledge: r = 0.62).

CONCLUSIONS

This study suggests that, for the selected sample, the prevention campaign was an effective tool to increase young people's knowledge of HIV/AIDS. The authors recommend dividing and tailoring interventions by gender to achieve even more efficient preventive future interventions.

Effective approaches for programming to reduce adolescent vulnerability to HIV infection, HIV risk, and HIV-related morbidity and mortality: a systematic review of systematic reviews

BACKGROUND

In 2012, an estimated 2.1 million adolescents were living with HIV. Though there are effective interventions to prevent and treat HIV infection, adolescents face specific barriers in accessing them. As a result, new infections and poor outcomes among HIV-infected adolescents are common. HIV programming for adolescents should focus on interventions of proven effectiveness and address underlying factors driving incidence and lack of effective treatment and care in this age group.

METHODS

We conducted a systematic review of systematic reviews to summarize the global data on effectiveness of 20 intervention types, to identify characteristics of effective interventions, and to explore evidence of how adolescents can access interventions with proven effectiveness. Interventions were in 2 broad categories: those designed primarily for adults and those designed specifically for adolescents. Where available, we evaluated the evidence of impact on the key outcomes: HIV risk, HIV transmission, and HIV morbidity and mortality.

RESULTS

Among the interventions designed for adolescents, there was high-quality evidence that in-school interventions and some interventions in geographically defined communities can positively impact important HIV-related outcomes, such as self-reported sexual risk behaviors. Interventions designed primarily for adults that had high-quality, consistent biological evidence of efficacy included voluntary medical male circumcision (VMMC), antiretrovirals for the prevention of mother-to-child transmission, HIV testing and counseling, HIV treatment, condom use, and provision of sterile injecting equipment to people who inject drugs. There was also an evidence of potential efficacy for oral preexposure prophylaxis and behavior change interventions among certain populations. There was a dearth of systematic review data on how best to enable adolescents to access the intervention types identified as having proven effectiveness among adults.

CONCLUSIONS

This series of reviews allowed us to rigorously and systematically review a large number of intervention types at once using a standard, transparent methodology. Eight key interventions showed clear evidence of effectiveness, with evidence of potential efficacy for some additional interventions among certain populations.

DISCUSSION

These priority interventions with proven effectiveness should be included in all HIV prevention programming for adolescents. There is a pressing need for more rigorous research on how best to enable adolescents to access these effective interventions.

The Peer Education Approach in Adolescents- Narrative Review Article

Adolescence is an important stage of human life span, which crucial developmental processes occur. Since peers play a critical role in the psychosocial development of most adolescents, peer education is currently considered as a health promotion strategy in adolescents. Peer education is defined as a system of delivering knowledge that improves social learning and provides psychosocial support. As identifying the outcomes of different educational approaches will be beneficial in choosing the most effective programs for training adolescents, the present article reviewed the impact of the peer education approach on adolescents. In this review, databases such as PubMed, EMBASE, ISI, and Iranian databases, from 1999 to 2013, were searched using a number of keywords. Peer education is an effective tool for promoting healthy behaviors among adolescents. The development of this social process depends on the settings, context, and the values and expectations of the participants. Therefore, designing such programs requires proper preparation, training, supervision, and evaluation.

Use of human rights to meet the unmet need for family planning

In this report, we describe how human rights can help to shape laws, policies, programmes, and projects in relation to contraceptive information and services. Applying a human rights perspective and recognising the International Conference on Population and Development and Millennium Development Goal commitments to universal access to reproductive health including family planning, we support measurement of unmet need for family planning that encompasses more groups than has been the case until recently. We outline how human rights can be used to identify, reduce, and eliminate barriers to accessing contraception; the ways in which human rights can enhance laws and policies; and governments' legal obligations in relation to contraceptive information and services. We underline the crucial importance of accountability of states and identify some of the priorities for making family planning available that are mandated by human rights.

Behavioural interventions for the prevention of sexually transmitted infections in young people aged 13-19 years: a systematic review

We systematically reviewed school-based skills building behavioural interventions for the prevention of sexually transmitted infections. References were sought from 15 electronic resources, bibliographies of systematic reviews/included studies and experts. Two authors independently extracted data and quality-assessed studies. Fifteen randomized controlled trials (RCTs), conducted in the United States, Africa or Europe, met the inclusion criteria. They were heterogeneous in terms of intervention length, content, intensity and providers. Data from 12 RCTs passed quality assessment criteria and provided evidence of positive changes in non-behavioural outcomes (e.g. knowledge and self-efficacy). Intervention effects on behavioural outcomes, such as condom use, were generally limited and did not demonstrate a negative impact (e.g. earlier sexual initiation). Beneficial effect on at least one, but never all behavioural outcomes assessed was reported by about half the studies, but this was sometimes limited to a participant subgroup. Sexual health education for young people is important as it increases knowledge upon which to make decisions about sexual behaviour. However, a number of factors may limit intervention impact on behavioural outcomes. Further research could draw on one of the more effective studies reviewed and could explore the effectiveness of 'booster' sessions as young people move from adolescence to young adulthood.

A life-skills-based HIV/AIDS prevention education for rural students of primary schools in China: what changed? What have we learned?

OBJECTIVE

To evaluate a four-hour life-skills-based HIV/AIDS prevention curriculum among 5th grade students in rural primary schools of Hainan province.

METHODS

The study included two stages. Stage one (September 2006-May 2007) was a pre-post-quasi experimental design; a total of 2,413 students aged 9 to 14 years from fifth grade classes of nine primary schools completed a baseline survey (1,720 students were in the intervention group, 693 in the control group), and over 98% of them took part in a short survey. The experimental curriculum was provided to the intervention group. At stage two (September 2008), a cross-sectional questionnaire was administered to 6,923 students in 7th grade classes of eight middle schools in the same study sites. There were 1,437 students in the intervention group when the curriculum was conducted.

RESULTS

Students tended to score higher in areas of HIV/AIDS related knowledge and attitudes, if they were younger than average, lived in the county seat, had access to the internet, and their parents had completed higher levels of education. Path analysis showed that, after controlling for characteristics such as family and community factors, the total effects of curriculum on knowledge in the short-term model increased remarkably compared with the baseline, and maintained major contributions to knowledge in the mid-term model. The positive effect of knowledge on attitudes was significantly improved in the short-term model as well.

CONCLUSION

A life-skills based curriculum can improve HIV/AIDS related knowledge and self-perceived level of life-skills among primary school students in rural areas in a short time, and these positive effects can still be observed at least 2 years post participation in the curriculum.
