A program addressing major public health challenges

Held since 2016, this must-attend scientific event in public health is open to all and brings together nearly 1,200 French, European, and international experts: members of the scientific community, policymakers, civil society representatives, and stakeholders from the national public health network. Its purpose is to promote the sharing of experiences and best practices, as well as to provide context for the major challenges and key lessons in public health and public policy, with the aim of fostering an environment conducive to population health. French and international
speakers, as well as experts from Santé publique France, will present their latest research and explore current topics, sharing their experiences and expertise in public policy aimed at promoting population health. They will also discuss a variety of topics to put working methods and their resulting outcomes into perspective at the regional, national, European, and international levels.
The day’s program includes:

• A plenary session on the theme of “One Health” 
• Eight parallel sessions focusing on major public health challenges, with innovation as the common thread:
  • The challenges of parenting and perinatal mental health;
  • Health messages regarding products harmful to health;
  • The evaluation and implementation of digital mental health interventions in light of evidence and ethics;
  • From idea to action: how does co-creation transform public health?;
  • 15 Years of Innovation in Biomonitoring and Its Future Prospects;
    • “Reaching Out” to Engage Hard-to-Reach Populations;
  • Innovation in the Face of Exceptional Public Health Events;
  • Epidemiology “in troubled waters.”
