Mental health is fundamental to overall health, yet its determinants extend far beyond individual diagnosis. Suicide alone accounts for more than 700,000 deaths globally each year, representing a major public health concern across age groups and regions.

This episode examines:

• The global epidemiology of mental disorders and suicide• Social determinants - poverty, unemployment, social isolation• Early-life adversity and trauma• Substance use and comorbidity• Gender differences in suicide patterns• Cultural and regional variation• Means restriction and lethal method availability• Media reporting and contagion effects• School, workplace, and community-based prevention• The integration of mental health into primary care

Public mental health requires a population lens. It considers not only treatment services, but also housing policy, education systems, employment structures, and social cohesion. Suicide prevention in particular demonstrates the power of structural intervention - including means restriction, responsible media reporting, and crisis service accessibility.

Mental wellbeing is shaped by belonging, stability, opportunity, and safety. Prevention must therefore extend beyond clinics into communities.
