Community Mobilisation and Peer/Youth Engagement - Fewer Young Men Reporting Sexual Debut

Wed, 04/05/2023 - 09:54

Strategy researched

Community mobilisation, peer education, supporting health workers to provide youth-friendly sexual health services, and peer condom social marketing

Impact achieved

The intervention substantially improved knowledge, reported attitudes and some reported sexual behaviours, especially in boys, but had no consistent impact on biological outcomes within the 3-year trial period. For example, the proportion of young men reporting sexual debut during follow-up was 60% in the intervention and 72% in the comparison communities. Similarly, the proportion of male subjects reporting more than one sexual partner in the past year was significantly lower in the intervention (19%) than in the comparison communities (28%), but no significant difference was seen in female participants. The proportions who reported initiating condom use during follow-up were substantially and significantly higher in intervention communities among both male (39% compared to 28% in control) and female to participants (38% in intervention and 28% in control). The proportions reporting condom use at last sex were also higher in intervention communities in both sexes.

Biological and behavioural impact of an adolescent sexual health intervention in Tanzania: a community-randomized trial

Excerpt from Abstract

"The intervention had a significant impact on knowledge and reported attitudes, reported sexually transmitted infection symptoms, and several behavioural outcomes. Only five HIV seroconversions occurred in boys, whereas in girls the adjusted rate ratio (intervention versus comparison) was 0.75 [95% confidence interval (CI) 0.34, 1.66]. Overall HSV2 prevalences at follow-up were 11.9% in male and 21.1% in female participants, with adjusted prevalence ratios of 0.92 (CI 0.69, 1.22) and 1.05 (CI 0.83, 1.32), respectively. There was no consistent beneficial or adverse impact on other biological outcomes. The beneficial impact on knowledge and reported attitudes was confirmed by results of a school examination in a separate group of students in mid-2002."

Why the focus on direct impact data?

A common challenge from policy makers, funders, community members, people directly experiencing development issues, and governments is: Demonstrate your Impact. Prove that what you are doing works. The high quality, highly credible data presented on the cards below is designed to help you answer that question for your social change, behaviour change, community engagement, communication and media for development, strategy formulation, policy engagement and funding initiatives. At this link filter the research data to your specific interests and priorities

Why a playing cards design?

There is a physical pack of cards with this data (to get a copy please request through the comment form for any card). The card approach allows for easy identification and selection of relevant direct impact data in any context. For example if talking with a donor and you need to identify proof of impact say "take a look at the 7 of Hearts". Quick access can be provided to high-quality data for many areas of your work – funding, planning, policy, advocacy, community dialogue, training, partner engagement, and more. A card deck is also engaging, easy to use and share, a conversation starter, and a resource - and they are fun and different. So we kept that design for the online images as it can serve similar purposes.
