Process of developing the National Health in All Policies Framework to address social determinants of health in Tanzania Mainland: lessons learned, 2018 - 2022.

Introduction: social determinants of health (SDH) are the non-medical factors that contribute to various infectious and non-infectious diseases in Tanzania. Studies suggest that SDH account for 30-55% of health outcomes globally. Most SDH are outside the mandate of the health sector; hence, multi-sectoral collaboration through Health in All Policies (HiAP) is critical. Health in All Policies looks at public policies across sectors that consider health implications of decisions, seek synergies, use resources and avoid harmful health impacts to improve population health and health equity. This paper demonstrates lessons learned from the process of developing National HiAP Framework in Tanzania Mainland to address SDH. It is expected that countries will be able to learn and adopt what deems fit in their context as they address SDH to improve population health. Methods: different methods were used to promote multi-sectoral collaboration in addressing SDH through HiAP. They included consultations with Prime Minister's Office (PMO) as the coordinator of Government business for their buy-in. High-level advocacy meetings of Directors of Policy and Planning and Permanent Secretaries from sectoral ministries were conducted to move forward the HiAP agenda. Capacity building was provided for sectoral Ministries to understand HiAP concept and SDH. Interministerial collaboration meetings were convened to bring sectors together to identify SDH issues and key areas for inter-sectoral collaboration and develop National HiAP Framework to address SDH. Health in All Policies Secretariat coordinates the HiAP activities. Results: it has been noted that almost every sectoral ministry has a health component in its policy which contributes to the Tanzanian population's health. In this regard, every sectoral ministry has a role to play in addressing SDH for sustainable development. Political will is key in moving forward the HiAP agenda. The role of PMO is significant to ensure inter-sectoral collaboration. Achieving the national and Sustainable Development Goals require strong collaboration among sectors and stakeholder coordination at all levels through HiAP. Conclusion: implementing HiAP is a win-win situation. It enhances inter-sectoral collaboration, benefiting each sector to achieve its health-related strategic indicators and ultimately achieve national and global goals.
