Sexual Health

Family-based sexual health interventions for adolescents in low- and middle-income countries: systematic analysis and meta-analysis.

TL;DR

Family-based sexual health interventions significantly improved adolescents' sexual health knowledge in low- and middle-income countries, but their impact on attitudes, practices, and family communication around sexual health was inconsistent.

Key Findings

Family-based sexual health interventions (FBSHI) significantly improved adolescents' sexual health knowledge in low- and middle-income countries.

  • This was identified as one of the two key themes emerging from the systematic review.
  • The review included nine studies with 2404 adolescent participants and their families.
  • Meta-analysis was conducted using a random-effects model.
  • Studies were published between January 2000 and October 2023 and sourced from five electronic databases.

The impact of FBSHI on adolescents' sexual health attitudes, practices, and family communication around sexual health topics was inconsistent.

  • This was identified as the second key theme of the systematic review.
  • Inconsistency was observed across the nine included studies.
  • The review covered outcomes reported by adolescents aged 10-19 years.
  • Studies used experimental or quasi-experimental designs to evaluate effectiveness.

Combined interventions involving both adolescents and their parents were highlighted as important for eliciting better sexual and reproductive health outcomes.

  • The review emphasized the importance of including parents alongside adolescents as a key component of effective interventions.
  • Family members included in interventions encompassed parents, siblings, or primary caregivers.
  • This finding emerged from synthesis of nine studies conducted in LMIC settings.

The systematic review identified significant geographical gaps, particularly the under-representation of Asian countries in FBSHI research in LMICs.

  • Future research was recommended to prioritize under-represented geographical regions such as Asia.
  • The review covered LMICs broadly but found limited coverage of Asian settings.
  • Culturally adopted and contextually relevant material was highlighted as necessary to increase acceptability and effectiveness in LMIC settings.

The systematic review included nine studies with a total of 2404 adolescent participants and their families, all conducted in low- and middle-income countries.

  • Eligible studies required adolescents aged 10-19 years and their family members to be included in a key intervention component.
  • Studies were required to use experimental or quasi-experimental designs.
  • Outcomes had to be sexual and reproductive health outcomes reported by adolescents.
  • Searches spanned five electronic databases covering publications from January 2000 to October 2023.

What This Means

This research synthesized evidence from nine studies involving over 2,400 adolescents and their families across low- and middle-income countries (LMICs) to understand whether family-based sexual health programs actually work in these settings. The researchers searched major academic databases for studies published over roughly two decades (2000–2023) and used statistical methods to combine results where possible. The review found that programs involving family members — such as parents, siblings, or caregivers — alongside adolescents were effective at improving young people's knowledge about sexual health. However, whether these programs changed attitudes, behaviors, or how openly families talked about sexual health topics was much less consistent across the studies. Programs that engaged both adolescents and their parents together appeared to produce better results than those targeting only one group. This research suggests there is a meaningful gap in where these programs have been tested — particularly in Asia — and that existing programs may not always account for local cultural contexts, which could limit how well they work. Policymakers and program designers in LMICs may benefit from developing interventions that are specifically tailored to local cultures and that actively involve parents alongside young people, rather than relying on programs designed for higher-income settings.
