Introduction to Public Health Quiz

Introduction to Public Health

• Public health is the science and practice of protecting and improving the health of people and communities. It focuses on population health, emphasizing prevention, healthy behaviors, and environmental protection. It's a multidisciplinary field.

• The scope of public health includes infectious and chronic diseases, environmental health, mental health, injury prevention, health equity, and social determinants of health. It operates locally, nationally, and globally, involving various sectors.

• Core functions of public health are assessment (monitoring health status), policy development (creating and implementing health plans), and assurance (ensuring access to services and enforcing regulations).

• Ten essential public health services include assessing population health, investigating hazards, communicating effectively, strengthening communities, creating policies, utilizing legal actions, enabling equitable access to care, building a skilled workforce, improving through evaluation, and maintaining strong organizational infrastructure.

Public Health vs. Medical Model

• Public health focuses on population health through prevention and promotion, acting in communities and aiming for long-term outcomes.

• The medical model focuses on individual patient care through diagnosis and treatment, operating in clinics and hospitals, and targeting immediate health outcomes.

Assessment Methods in Public Health

• Public health assessment systematically collects, analyzes, and interprets health data to identify problems, set priorities, and evaluate interventions. It's a continuous, cyclical process.

• Types of assessments include community health assessments, health impact assessments, environmental health assessments, needs assessments, risk assessments, health equity impact assessments, and surveillance systems.

Data Sources for Public Health Assessments

• Primary data sources include surveys, interviews, focus groups, and biomarkers.

• Secondary data includes vital statistics, disease registries, national health surveys, electronic health records, and claims data.

Concept of Health

• The WHO defines health as a state of complete physical, mental, and social well-being, not merely the absence of disease. This holistic approach emphasizes positive health but may be unrealistic in its "completeness" and doesn't account for dynamic health states.

Social Determinants of Health (SDOH)

• SDOH are environmental conditions affecting health outcomes, including economic stability, education access, healthcare access, neighborhood environment, and social context. They account for approximately 80% of health outcomes.

Health Equity

• Health equity means everyone has a fair opportunity to achieve their highest health level. It includes addressing systemic barriers, rectifying historical injustices, ensuring equitable resource distribution, and promoting cultural competence.

Modern Public Health Definition

• Healthy People 2030 defines public health as promoting and protecting the health of people and communities where they live, learn, work, and play. It emphasizes collective action, population focus, and prevention.

Key Terms in Public Health

• Epidemiology studies the distribution and determinants of health-related states in populations to control health problems. Key concepts are incidence and prevalence, risk factors and causation, study designs, measures of association. It provides an evidence base for interventions.

• Health promotion enables people to increase control over and improve their health (WHO Ottawa Charter, 1986). Strategies include building healthy public policy, creating supportive environments, strengthening community action, and developing personal skills.
