Features of successful sexual health promotion programs for young people: findings from a review of systematic reviews
Abstract
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.
1 INTRODUCTION
Young people have higher prevalence of sexual and reproductive health (SRH) problems compared to the broader population, impacting individual health and wellbeing as well as broader social and population consequences.1-3 The median age of sexual debut is during adolescence, age 16-17 years,4, 5 and it is important to target young people through health promotion initiatives to mitigate the risk and burden of SRH problems in this population group before they become at risk. In settings such as Australia, high rates of chlamydia infection,6 unintended pregnancy,7, 8 and sexual violence9 among young people remain a major cause for concern. Although there is a large volume of literature addressing the effectiveness of health promotion initiatives, the impact of programs on SRH outcomes such as behaviour and health are often mixed (e.g. 10, 11). There is a need to identify features of effective programs in order to improve the design of ongoing sexual health interventions.
2 METHODS
To inform health promotion practitioners in the design and implementation of sexual health promotion for young people, we conducted a systematic review of reviews to assess the effectiveness of health promotion interventions in improving SRH of young people in high-income countries.12 We chose to synthesise literature by means of a systematic review of reviews to compare and consolidate findings from a substantial number of existing reviews and provide a clear summary for decision-makers and health promotion practitioners. Using predefined criteria, we identified and collated systematic reviews published from 2005-2015 which reviewed interventions aimed at improving SRH, focused on adolescents or young people aged 10-24 years, reported on SRH outcomes (pregnancy, sexually transmissible infections [STIs], condoms/contraceptive use, risky sexual behaviour, sexual healthcare access or intimate partner violence [IPV]), and included primary studies predominantly conducted in high-income countries. We searched in Cochrane library (CDSR, DARE, HTA, CENTRAL); Ovid MEDLINE (Medical Literature Analysis and Retrieval System Online; indexed and non-indexed); Embase; CINAHL; PsycINFO (Database of Psychological Literature); and Scopus. The search strategy used Boolean Operators to combine specified syntax terms for youth (e.g. “young people,” or teen* or adolescent*); outcome (e.g. “Reproductive health” or “sexual risk” or “unintended pregnan*” or “sexual violence” or “sexually transmitted infection”); and intervention (e.g. “health promotion” or “social marketing” or “community health service” or “health education” or “sex education”). Both narrative reviews and meta-analyses were included. We extracted data on program features and SRH outcomes from each review.
The systematic review of reviews focused on assessing the strength of evidence of styles, settings and types of health promotion initiatives using a matrix based on consistency of findings and quality of review. Detailed information with quality of evidence and support for improving particular outcomes is provided in the report, published elsewhere.12 This manuscript focuses on common programmatic elements that improved SRH outcomes in young people as reported in the interpretation and discussion of included systematic reviews. Due to the limitations of assessing programmatic details in a review of reviews (see Discussion limitations), these elements are often only described anecdotally in systematic reviews. At the discretion of the primary paper authors, they may reflect statistical or non-statistical findings as well as anecdotal reports and reflection. We have collated these features so that they can be considered in future program designs, as an extension to the more structured and qualified findings of the overall review.
3 RESULTS
We identified 66 systematic reviews that met our inclusion criteria (see12 for full report). Forty-three (65%) reviews explicitly discussed program components affecting intervention effectiveness and are the focus of this report. Of these 43 reviews, six (14%) reported that there were insufficient data to make conclusions on best practices or that no program variables were specifically found to be more effective while 37 (86%) systematic reviews reported on program features which were anecdotally or statistically associated with improved program effectiveness and success. These features are listed in Table 1.

In the systematic reviews studied, there was conflicting evidence on whether programs should focus on more than one outcome (e.g. pregnancy and safer sex; broader health focus)13, 14 or have clear and narrowly defined health goals.11 Contrary with the majority of findings, one review reported that brief-single sessions were at least as effective as longer interventions.13
4 DISCUSSION
We have characterised programmatic features which are highlighted in systematic reviews as key to success in SRH promotion. Although systematic reviews and reviews of reviews provide a means to synthesise large amounts of data, they pose challenges to assessing programmatic details. Due to heterogeneity or insufficient detail in reporting, these can be difficult to statistically compile and details may get lost in each layer of review. As such, one-third of included reviews did not discuss programmatic components in terms of intervention effectiveness. By focusing on review authors’ ‘takeaway’ points and including anecdotal suggestions, this manuscript adds value to the strength of evidence findings12 and provides suggestion to guide programmatic implementation of SRH promotion for young people.
Despite the breadth of health themes, intervention styles and program settings included, this review demonstrates marked consistency between systematic reviews about factors associated with intervention effectiveness. Investments into interventions which are multifactorial in terms of content, setting and level of influence (including family), longer term, tailored to sub-groups of the population and with a focus on skills-building should be prioritised in SRH strategies to meet targets for reducing the incidence of STIs, unintended pregnancy and sexual violence among young people. These features do not constitute ‘new’ knowledge, and indeed many of the above recommendations also correspond to existing theory14, 15 and health promotion guidelines.16
We believe there are plausible mechanisms through which the above-mentioned features could improve program effectiveness. For example, longer term interventions and involvement of family may benefit through message consistency and reinforcement; skills-building—which might incorporate practical exercises in using a condom, communication strategies or negotiation skills—may support the application of knowledge-based learning; and tailoring interventions to be sub-group specific or sensitive may improve the relevance and accessibility of interventions to their target population(s).
Findings on programmatic components highlighted in interpretation and discussion mostly supported evidence from the broader systematic review of reviews, which used a matrix based on consistency of findings and quality of review to classify strength of evidence.12 In particular, there was good evidence of effectiveness for education interventions incorporating skills-building (knowledge/attitudes, behaviour) and communication skills (knowledge/attitudes, behaviour) and condom demonstration (behaviour, knowledge, STI prevalence). However, the evidence for programs involving family or parents was largely inconsistent. The strength of evidence for multicomponent interventions was mixed but this may be due to differences in the a priori description of ‘multicomponent’.
The persistence of intervention shortcomings, despite our better knowledge of what works, is in keeping with the well-documented gap in translation from research to practice.17-19 There are practical constraints in real-world practice on which translation is hinged, no matter the state of evidence. These include the inadequate sharing of knowledge among those designing, implementing and evaluating health promotion programs; poor access to peer-reviewed academic journals; limitations in organisational capacity, including workforce skill gaps; political or moral steering of programs; and reliance on short-term funding schemes.19-23 These will remain as significant barriers to the implementation of quality SRH program until they are acknowledged and addressed among researchers, funding bodies, decision-makers and program implementers alike. Systematic reviews can be excellent tools to guide practice; however, an abundance of available reviews on a topic such as sexual health promotion and varying quality and contrasting findings can make it difficult for those in position of decision-making or intervention design to navigate and implement findings.24 The conducting and publicly sharing of reviews of reviews such as this one is a small step towards making evidence readily available to practitioners who can then translate these into practice.
Through our review, we identified a large body of published evidence on SRH promotion for young people. Our ability to synthesise data and draw conclusions was limited by the quality of included systematic reviews, consistency of reporting on program factors, and heterogeneity of primary studies. Furthermore, the sometimes anecdotal nature of reporting program features may be subject to confirmation bias. Nonetheless, through consolidating the literature we identified coherent program features which have been found to add value to interventions across different areas of SRH. While reviews generally focus narrowly on one aspect of sexual health and behaviour, program objectives are often broader and intend to address more than one aspect of SRH. Our findings provide consistent evidence and grounding for optimising the design of SRH interventions for young people.
