Learning outcomes: Define health; describe different concepts and perspectives; list determinants of health; define globalization’s advantages and disadvantages on health and population.
Main content highlights:
Health definitions (lay view, professional view, WHO 1948 definition) and expansion to include social/economic productivity.
Dimensions of health: physical, mental, social; possible additions: spiritual, emotional.
WHO operationalization: health is multidimensional and not readily measurable by one metric; broad dimensions include physical, mental, social; spiritual/emotional considerations may be included.
Health determinants (Health Field Concept): four major determinants
A) Human Biology (genetics, hereditary factors; genetic counseling and engineering)
B) Environment (external to the host): food, water, air; climate; biological agents; psychosocial and economic factors; chemical hazards
C) Lifestyle/Behavior (individual actions): frequency, duration, purpose; smoking, diet, exercise, sexual behavior
D) Health Care Organization (resources, health service availability, accessibility, quality)
Ecological perspective: physical determinants, sociocultural determinants, community organization, behavioral determinants; diagrammatic representation (textual in the material).
In-text activity: List 3 factors affecting community health (Physical determinants, Health care organization, Sociocultural determinants).
Globalization and Health (2.3 section): Global interdependence; health is a global issue; potential positive/negative/mixed effects; externalities from disease spread, technology, bilateral agencies; labor markets, tobacco, obesity, environment; rapid disease spread; environmental and social inequalities; need for transnational solutions; policy implications and ethical questions discussed.
Conclusion: Health is defined, determinants identified, globalization discussed; next study session moves to disease causation models.
Study Session 2: Concept of Health II
Learning outcomes: Describe disease causation models; list 19th-century models; listing 20th-century models.
Main content:
Model of Disease Causation definition: a model represents a system with components and relationships; includes graphs, charts, decision trees.
19th-Century models:
1) Contagion theory – illness is contagious; quarantine and isolation measures; ships quarantines; cordons; household isolation; fumigation;
2) Supernatural theory – disease as punishment or divine will; used to justify poverty and governance; political implications;
3) Personal behaviour theory – disease results from individual behavior; empowerment and responsibility; supports democratic values;
4) Miasma theory – disease from odour of decaying material; links disease source and victims differently from others.20th-Century models:
1) Germ Theory – microorganisms cause disease; antibiotics and vaccines; criticisms (Thomas McKeown): health gains partly due to living standards, not solely vaccines/antibiotics.
2) Life Style Theory – unhealthy lifestyles cause chronic diseases; emphasizes individual behavior change but recognizes need for social change.
3) Environmental Theory – toxins in air, water, soil; occupational hazards; industrial production changes; debates over extrapolation from animals to humans and threshold levels.
4) Multi-Causal (Web of Causation) Theory – multiple, interacting factors for a single disease; limitations for direct policy guidance but foundational for complex prevention planning.In-text questions and answers emphasize identification of theories (19th vs 20th century).
Conclusion: Historical progression from single-cause models to multi-factorial, systems-based understandings; next session discusses Public Health definitions, history, and disciplines.
Study Session 3: Public Health
Core definition and scope: Public health is the art and science of preventing disease, prolonging life, and promoting health through organized community efforts; aims at the health of populations, not just individuals; engages biology, technology, social sciences, and politics.
Learning outcomes: History, definitions, core activities, major disciplines, ethics and public health challenges, relationship to clinical medicine.
History timeline highlights:
Ancient: Hammurabi code; Leviticus; Greco-Roman sanitation, aqueducts, public baths.
Middle Ages: disease seen as spiritual punishment; neglect of physical causes.
Renaissance to 18th century: environment recognized; vaccination (Jenner, 1796).
19th century: germ theory, pastuerian era, public health reforms; Florence Nightingale; broad public health reforms.
Key definitions:
Acheson Report: Public health is the science and art of preventing diseases, prolonging life, promoting health, through organized community effort.
Detels (2003): Public health goal is the biological, physical, and mental well-being of all members of society, with emphasis on equity.
Key terms and concepts: Health promotion; Prevention; Levels of prevention (Primary, Secondary, Tertiary).
Functions of Public Health: 13+ core actions (e.g., prevent disease, promote healthy lifestyles, monitor health status, policies, ensure access to care, disaster response, research, training).
Major Disciplines in Public Health: Nutrition, Reproductive Health, Environmental Health, Health Education, Epidemiology, Health Economics, Biostatistics, Health Service Management, Ecology, Research, Demography, etc. (with brief definitions).
Core activities in public health: Prevent epidemics, protect environments/workplaces/food/water, promote health behaviors, monitor health status, mobilize communities, respond to disasters, ensure quality/accessible care, develop new insights, inform policy.
Public health ethics and challenges: Social justice vs market justice; collective scope vs individualism; economic impacts; paternalism vs libertarianism; public health and religion/morality; surveillance vs cure; cost-benefit analysis; value judgments in health policy.
Relationship to clinical medicine: Distinct but interdependent; public health focuses on populations; clinical medicine focuses on individuals; access to high-quality care is a right and a requirement of good public health; direct and indirect public health approaches both matter.
Conclusion: Sets stage for next session on health and culture; references and readings provided for deeper exploration.
Study Session 4: Health and Culture
Core definitions: Culture is the complex whole including knowledge, beliefs, arts, morals, laws, customs, and capabilities; learned behavior shaped by values and social norms; levels of culture include concrete (artifacts), behavioral (language, gender roles, social practices), symbolic (values, religion, worldviews).
Relationship to health: Culture influences attitudes toward health problems, disease perceptions, prevention/treatment choices, and health provider use; meanings of health/illness are culturally bound.
Insider vs outsider perspectives: Insider view is culture-bound; outsider view is external analysis; ethnocentrism vs cultural relativism; practical caution about imposing Western biomedical norms on other cultures; holism as an analytical approach.
Insider vs outsider example: perceptions of worms in children; disease vs illness distinction; how some conditions may be real in one framework but not recognized in another; need for culturally appropriate health interventions.
Conclusion: Sets up understanding for traditional medicine and family health in subsequent modules; emphasizes cultural sensitivity and adaptable health strategies.
Module 2: Traditional Health Care Practices
Study Session 1: Origin of Traditional Medicine
Traditional medicine history: roots as old as humanity; Africa as a primary context; herbs used for healing; WHO (1996) recognizes THPs as competent healers using plant/animal/mineral substances; traditional medicine is integral in many communities; Alma Ata (1978) recognized traditional medicine as important to national health systems; 2000–2010 African Traditional Medicine Decade.
Types of traditional healers (WHO and Nigerian context): Traditional Herbalists; Traditional Birth Attendants (TBAs); Traditional Surgeons (tribal marks, circumcision, minor surgeries); Traditional Medicinal Ingredient Dealers; Traditional Psychiatrists (diviners/spirits/healers).
Growing patronage: due to access, affordability, cultural alignment, and perceived efficacy; traditional medicine contributes to maternal, child health, and HIV/AIDS management; thousands of practitioners relative to physicians in rural settings; WHO/UN reports and Nigerian policy discussions.
Contributions to healthcare development: traditional medicine widely used globally; potential sources of pharmacological knowledge (analgesics like aspirin, antivascular agents); manpower coverage; reduction in child mortality; TBAs expanding primary health care reach; integration with modern medicine increasing.
Methods of traditional healing: herbs; divination; ritual washing; diagnosis through observation and symbolic means; knowledge systems and apprenticeship; potential for both healing and harmful uses.
Challenges facing traditional medicine: inadequate policy frameworks; limited funding; poor documentation; lack of national and school curricula integration; quality control and standardization issues; misidentification/adulteration of medicinal plants; ethical and intellectual property concerns; need for collaboration with orthodox medicine; sustainability and conservation concerns; issues of regulation and safety.

Study Session 4: Health and Development
What is development? Definitions vary; modern view includes physical and mental progress shaped by social, economic, institutional processes; development aims to increase availability, improve living standards, expand opportunities, and improve human capital.
Difference between development and economic growth: development is broader (quality of life, equity, social, political, environmental dimensions), while economic growth is primarily per-capita income growth; growth can occur without development.
The role of health in development: health is a key driver of economic development; healthy populations enable productivity; health investment supports human capital; health interventions influence long-term development outcomes.
Household Livelihood Security (HLS): defined as adequate and sustainable access to income and resources to meet basic needs; health is a critical component of livelihood security; health status affects income and resilience to shocks; bidirectional relationship between health and income.
Health and the Millennium Development Goals (MDGs): overview of the eight MDGs (eradicate poverty, universal primary education, gender equality, reduce child mortality, improve maternal health, combat HIV/AIDS, malaria and other diseases, environmental sustainability, global partnerships). Specific targets include reduction in under-five mortality, maternal mortality, etc.; discussion of MDG indicators and monitoring.
Sustainable Development Goals (SDGs): 17 global goals designed to end poverty and hunger by 2030; interconnected goals across health, education, gender equality, clean water, energy, economic growth, industry, climate action, life below water, life on land, peace and strong institutions, and global partnerships. The notes provide a detailed, paragraph-level description of each SDG, including targets such as universal health coverage, equity, sustainable cities, climate action, and the global partnership for sustainable development.
