Key Social Norms Take-aways Adolescents in rural Zambia face conflicting social norms: strong disapproval (injunctive norms) of premarital sex, contraceptive use, and open conversations about sexuality, alongside a widespread (descriptive) norm of transactional sex driven by poverty and peer influence. The RISE intervention reinforced abstinence messaging but failed to shift the restrictive norms that limit girls’ agency and access to contraceptive information and services. Interventions must engage more deeply with these norms and the broader structural context to be effective.

Objectives To explore how social norms shape adolescent sexual behavior and early pregnancy in rural Zambia, and how these norms interact with structural factors like poverty and education within the context of the RISE intervention.

Methods This qualitative sub-study used in-depth interviews, focus group discussions, and participatory peer research with adolescents, parents, and community members across five rural communities. Data were collected over three phases between 2017 and 2018 and analyzed using social norms theory, focusing on injunctive (what is approved) and descriptive (what is practiced) norms.

Intervention Details RISE (2016–2018) combined youth clubs, community meetings, and economic support to reduce early childbearing and improve school retention. Youth clubs provided SRH and life skills education. Community meetings aimed to support norm change but did not directly address contraception. Cash transfers were provided to girls and families, and secondary school fees were covered.

Results Adolescent girls were expected to abstain from sex and avoid relationships. Premarital sex, pregnancy, and contraceptive use were heavily stigmatized. At the same time, many girls engaged in transactional sex due to poverty and peer dynamics. Conversations about sex with adults were taboo, and myths about contraception (e.g., causing infertility or disability) persisted. Although economic support helped some girls avoid risky relationships, it did not shift the deep-rooted norms or improve intergenerational communication.

Conclusions Effective SRH interventions must go beyond abstinence-focused education. They need to challenge harmful norms, promote accurate SRH knowledge, foster open dialogue, and address economic barriers. Sustained community engagement—including parents, teachers, and health workers—is essential for transforming the social environment and supporting girls’ reproductive autonomy.
