    GPH 86: Urban Health

    Urbanisation is one of the defining demographic shifts of the modern era. Cities concentrate opportunity, innovation, healthcare, and economic growth - yet they also amplify inequality, environmental exposure, injury risk, communicable disease transmission, and chronic disease burden. This chapter examines the determinants of health within urban environments: housing quality, sanitation, transport systems, air pollution, green space, social cohesion, informal settlements, and governance structures. It explores both the benefits of urban density - access to services, education, and employment - and the vulnerabilities associated with overcrowding, slums, violence, and infrastructure strain. Urban health is presented as a systems challenge. Effective strategies require integrated planning across sectors: housing, transport, environmental regulation, safety, and social protection. The city becomes both risk and remedy. Key Takeaways * Urban populations are growing rapidly, particularly in low- and middle-income countries. * Cities concentrate both health opportunity and health risk. * Social and spatial inequalities are often magnified in urban settings. * Environmental exposures such as air pollution and unsafe housing drive morbidity. * Informal settlements pose unique public health challenges. * Integrated urban planning and cross-sector governance are central to improving urban health. * Healthy cities require structural, not merely clinical, interventions.

    GPH 85: War

    War reshapes the health of populations at every level. Beyond battlefield deaths, conflict drives displacement, famine, infectious disease outbreaks, environmental contamination, collapse of health systems, and generational trauma. This chapter examines the epidemiology of armed conflict, including direct mortality, civilian injury, landmines, chemical and biological weapons, and the destruction of water, sanitation, and health infrastructure. The ripple effects extend into forced migration, malnutrition, interrupted vaccination programmes, and long-term mental health consequences. We explore international humanitarian law, global treaties on weapons, and the role of humanitarian assistance. War is framed not only as geopolitical failure, but as a predictable generator of preventable public health crises. Public health in conflict becomes a discipline of preparedness, protection, reconstruction, and accountability. Key Takeaways * The majority of war-related deaths are indirect, resulting from disease, malnutrition, and infrastructure collapse. * Civilian populations, particularly women and children, bear disproportionate burden. * Forced migration and displacement profoundly affect health outcomes. * Landmines, chemical weapons, and biological agents create long-term public health threats. * Health system destruction amplifies mortality from otherwise preventable conditions. * International humanitarian law and coordinated humanitarian response are central to mitigation. * War prevention and peace-building are fundamentally public health priorities.

    GPH 84: Interpersonal Violence

    Interpersonal violence is a major contributor to premature mortality, disability, and psychological trauma worldwide. This chapter approaches violence through an epidemiological and structural lens, examining how violence emerges from intersecting risk factors across the individual, relational, community, and societal levels. We explore child maltreatment, intimate partner violence, youth violence, sexual violence, and elder abuse. Patterns of risk - including poverty, alcohol misuse, gender inequality, exposure to violence in childhood, and social exclusion - are examined alongside protective factors and resilience pathways. The chapter emphasises that violence is preventable. Public health strategies move upstream: strengthening families, addressing harmful norms, regulating alcohol access, improving urban design, and embedding violence prevention within policy and community systems. Violence is reframed not as moral failure, but as preventable harm embedded in social ecology. Key Takeaways * Interpersonal violence is a significant cause of death, injury, and long-term mental health consequences. * Violence operates across ecological levels: individual, relationship, community, and societal. * Risk factors include childhood adversity, alcohol misuse, gender inequality, and social deprivation. * Intimate partner violence and child maltreatment have profound intergenerational effects. * Effective prevention requires multi-sectoral approaches, including legislation, community engagement, education, and structural reform. * Violence prevention is a core public health function.

    GPH 83: Injury Prevention

    Injuries represent one of the leading causes of death and disability globally, particularly among children, adolescents, and young adults. This chapter examines injury through a public health lens: not as isolated events, but as predictable and preventable outcomes shaped by environment, behaviour, policy, and systems. We explore the epidemiology of injuries - road traffic incidents, falls, drowning, burns, poisoning, occupational trauma - alongside the Haddon Matrix and systems-based approaches to prevention. The chapter emphasises that injuries are not “accidents” but events with identifiable risk factors and modifiable upstream determinants. From legislation and enforcement to environmental design and behavioural interventions, injury prevention becomes a model of applied public health: combining surveillance, engineering, education, and policy. Key Takeaways * Injuries are a major contributor to global mortality and disability, especially among young populations. * The Haddon Matrix provides a structured framework for analysing injury across host, agent, and environment dimensions. * Road traffic injuries are among the most significant preventable causes of death worldwide. * Effective prevention requires multi-level interventions: legislation, environmental modification, behavioural change, and emergency response systems. * Injuries reflect social gradients and structural inequities. * Public health reframes injury as preventable rather than accidental.

    GPH 82: Alcohol

    Alcohol is deeply embedded in many cultures, economies, and social rituals - yet it remains a major contributor to global morbidity and mortality. Harmful alcohol use is associated with liver disease, cancers, cardiovascular conditions, injuries, violence, mental health disorders, and social disruption. This episode examines: • Global patterns of alcohol consumption• Per capita intake and regional variation• Alcohol-attributable mortality and disability-adjusted life years (DALYs)• Acute harms: injuries, road traffic crashes, violence• Chronic harms: liver cirrhosis, cancers, cardiomyopathy• Alcohol and mental health• Alcohol marketing, pricing, and availability• Population-level control strategies (taxation, advertising restrictions, minimum unit pricing)• Screening and brief interventions in clinical practice Alcohol-related harm extends beyond the individual drinker. Families, communities, and health systems bear substantial indirect consequences. As with tobacco, alcohol is shaped by commercial determinants - marketing practices, pricing strategies, and political influence. The chapter frames alcohol control as a balance between cultural norms and population health priorities, emphasizing evidence-based regulatory strategies alongside clinical and community interventions. ──────────────────────────── Key Takeaways • Alcohol contributes substantially to global mortality and morbidity• Harm includes both acute injury and chronic disease• Population-level strategies (pricing, availability controls) are highly effective• Alcohol use intersects with mental health and violence• Commercial influences shape consumption patterns• Screening and brief interventions reduce harmful drinking• Public health approaches extend beyond individual responsibility This is a public episode.

    GPH 81: Public Health Aspects of Illicit Psychoactive Drug Use

    Illicit psychoactive drug use is a significant contributor to global morbidity and mortality. Although its overall burden is smaller than that attributable to tobacco or alcohol, illicit drug use generates substantial health, social, and economic consequences - including overdose deaths, infectious disease transmission, mental health disorders, and social disruption. This episode explores: • Global prevalence patterns of cannabis, opioids, cocaine, and amphetamine-type stimulants• Drug-related mortality and disability-adjusted life years (DALYs)• Geographic variation in production, trafficking, and consumption• Injection drug use and the transmission of HIV and hepatitis• Overdose epidemiology and the opioid crisis• The neurobiology of dependence and relapse• Harm reduction strategies (needle exchange, opioid substitution therapy)• Prevention, treatment, and policy responses• The intersection of drug use, incarceration, and social inequity Illicit drug use is shaped not only by individual vulnerability but by structural forces - production economies, trafficking routes, criminal justice systems, and social marginalization. Public health responses increasingly recognize that punitive approaches alone are insufficient. The episode highlights the importance of evidence-based harm reduction, treatment accessibility, and integrated policy approaches that address both individual behaviour and structural determinants. ──────────────────────────── Key Takeaways • Illicit drug use contributes significantly to global morbidity and mortality• Cannabis is the most widely used illicit drug globally• Opioid use is strongly associated with overdose and infectious disease transmission• Harm reduction strategies reduce HIV, hepatitis, and overdose risk• Substance use disorders are chronic, relapsing conditions• Criminal justice responses have population health consequences• Public health frameworks prioritize prevention, treatment, and structural reform This is a public episode.

    GPH 80: Tobacco

    Tobacco use remains the single largest preventable cause of premature mortality worldwide. It is a driver of cardiovascular disease, cancers, chronic respiratory disease, and a wide range of other conditions. Despite decades of evidence, tobacco continues to exert a profound influence on global health, particularly in low- and middle-income countries where industry expansion has been most aggressive. This episode explores: • The epidemiology of tobacco use globally• Patterns of consumption across regions and age groups• The health consequences of smoking and smokeless tobacco• Second-hand smoke and population-level exposure• The political economy of the tobacco industry• The WHO Framework Convention on Tobacco Control (FCTC)• Population strategies: taxation, advertising bans, plain packaging• Behavioural and pharmacological approaches to cessation• Emerging products, including e-cigarettes Tobacco is not merely a behavioural issue - it is a structural and commercial determinant of health. Effective control requires legislation, taxation, public education, clinical support, and vigilance against industry tactics that undermine policy. The chapter frames tobacco control as one of the clearest examples of public health success when evidence, policy, and advocacy align - yet also as a reminder that gains are fragile and require sustained commitment. ──────────────────────────── Key Takeaways • Tobacco is the leading preventable cause of global mortality• Most tobacco-related deaths now occur in LMICs• Second-hand smoke contributes significantly to disease burden• Taxation is among the most effective control strategies• Comprehensive policy requires legislative and behavioural approaches• Industry interference remains a central barrier• Tobacco control demonstrates the power of population-level intervention This is a public episode.

    GPH 79: Bioterrorism

    Bioterrorism represents the deliberate release of biological agents to cause illness, fear, and societal disruption. Although rare compared to naturally occurring outbreaks, the consequences of intentional biological release can be profound, requiring rapid detection, coordinated response, and effective risk communication. This episode examines: • Historical examples of biological weapon use• Categories of biological threat agents• Detection and early warning systems• Laboratory capacity and forensic epidemiology• Emergency preparedness and response planning• Public communication under uncertainty• Health system surge capacity• Ethical and legal frameworks• The intersection between biosecurity and public trust Bioterrorism preparedness relies on many of the same systems required for emerging infections: surveillance networks, rapid diagnostics, inter-agency coordination, and clear communication. The difference lies in intent - deliberate harm rather than natural emergence. The episode explores how public health must balance vigilance with proportionality, ensuring readiness without amplifying fear. Effective response requires trust, transparency, and collaboration between health authorities, security agencies, and communities. Preparedness strengthens resilience not only against intentional threats, but against all biological hazards. ──────────────────────────── Key Takeaways • Bioterrorism involves intentional release of biological agents• Preparedness overlaps with emerging infection response systems• Rapid detection and coordinated response are critical• Risk communication influences public behaviour• Laboratory and forensic epidemiology play central roles• Ethical and legal frameworks guide response• Public trust underpins effective crisis management This is a public episode.
