In response to the high maternal mortality in Afghanistan, the government emphasised enhancing antenatal care (ANC) coverage to improve skilled birth attendance and reduce maternal mortality. This study aimed to explain how and why ANC interventions worked, for whom, and under what circumstances in Afghanistan between 2000 and 2024.

A rapid realist review was conducted to identify underlying programme theories and examine contextual factors and key mechanisms influencing ANC outcomes, with input from a panel of national experts. Data were extracted using context–mechanism–outcome (CMO) configurations to develop and refine theories for policy recommendations.

From 3502 papers, 1860 duplicates were removed, 63 were screened for full text and 25 were included in the final review. In total, 29 CMOs were inferred across nine interventions, classified at individual, interpersonal, community and institutional levels. We found that ANC interventions could work best by empowering women and healthcare workers (HCWs), involving husbands, hiring female community health workers (CHWs), ensuring regular contact with the same HCWs, endorsing health messages by the government, incentivising CHWs and designing and implementing interventions using participatory approaches. Interventions are less successful when there is a lack of community trust in service quality or HCW qualifications, low decision-making ability among women, discomfort during travel to health facilities, adherence to traditional practices and beliefs, hiring CHWs from outside the community, chronic stress and lack of support among HCWs and unrecognised incentives.

Our evidence synthesis can inform donors, policymakers and implementers on how to design more effective ANC interventions to achieve better health outcomes in Afghanistan. By emphasising intervention evaluation and ANC quality improvement, it highlights the importance of key social elements, such as cultural norms, power dynamics, relationships, beliefs and trust, which are likely to maximise impact. Community involvement is essential for designing and implementing effective and sustainable ANC interventions.

Effective young adults’ sexual health education is crucial for promoting informed decision-making and healthy behaviours. National and international guidelines provide a framework for developing and implementing effective programmes. However, these guidelines may vary in their content, focus and recommendations. This scoping review protocol details a plan to map the literature on national and international young adults’ sexual health education guidelines. The review will focus on identifying key dimensions and characteristics of these interventions.

Guideline selection will be conducted using the Population, Intervention, Professionals, Outcomes and Healthcare setting/context framework. A comprehensive three-stage search of academic databases, grey literature and citation tracking will be conducted to identify all relevant literature. Data extraction will be performed by two independent researchers using a standardised, piloted data charting form to ensure accuracy and minimise bias. The form will capture key guideline characteristics. The process will be iterative, allowing refinement of variables for comprehensive data capture. Findings will be synthesised and presented using diagrams, tables and a narrative summary to provide a clear overview of the existing literature.

Adhering to all relevant guidelines and regulations, this study will proceed under the approval of the Ethics Committee of Shahroud University of Medical Sciences, Semnan, Iran. This scoping review will identify and examine the dimensions and characteristics of national and international guidelines for young adults’ sexual health education. By analysing the dimensions and characteristics of these guidelines, this review will identify commonalities, differences and gaps in the current landscape. The findings will have significant implications for policymakers, educators and researchers engaged in the development and implementation of young adults’ sexual health programmes. The results will be disseminated through publication in a relevant peer-reviewed journal to inform future research and practice in this field.
