Study Notes
Course Information
- Course: PHAR 658 - Foundations of Epidemiology I
- Chapter: Merrill Chapter 1
- Date: January 14, 2025
- Instructor: Preeti Pushpalata Zanwar, PhD, MPH, MS
Objectives
- Define epidemiology and understand the foundational vocabulary
- Define descriptive and analytic epidemiology
- Identify key activities performed in epidemiology
- Explain the role of epidemiology in public health practice and decision-making
What is Health?
- The absence of illness
- Six dimensions of health
Six Dimensions of Health
- Physical: Ability of the body to function properly, including physical fitness and daily activities
- Social: Ability to form satisfying relationships, interact with social institutions, and understand societal norms
- Mental: Ability to think clearly, reason objectively, and act appropriately
- Emotional: Ability to cope, adapt, and adjust; self-efficacy and self-esteem
- Spiritual: Feeling as part of a greater spectrum of existence; personal beliefs and choices
- Environmental: External factors (surroundings, occupation) and internal factors (genetics)
What is Public Health?
- Public health is the science and art of promoting health and extending life for the population
- Public health focuses on threats to health within a population (group sharing characteristics)
- The mission of public health is to ensure conditions that promote all six dimensions of health in the general population
What is a Population?
- A grouping of individuals sharing one or more observable or observed characteristics
- Data can be collected and evaluated from populations with shared attributes
- Examples of population characteristics include social, economic, family (marriage/divorce), work/labor force, and geographic factors
Public Health and Epidemiology
- Epidemiology is a central element of public health, viewed as its foundation due to its significant role
- Other important considerations within public health include biostatistics and health services
What is Epidemiology?
- Epidemiology is the study of the distribution and determinants of health-related states or events in human populations
- Epidemiology involves the application of the study to help prevent and manage health issues
Key Terms in Epidemiology
- Health-related states or events: Diseases (like cholera, influenza, pneumonia), mental illness, and conditions like physical activity, nutrition, environmental exposures, seat belt use, and health services provision/usage
- Events: Injury, drug abuse, and suicide
Why is Epidemiology the Foundation of Public Health?
- Epidemiology is central to the three main public health roles (functions):
- Assessing and monitoring communities and populations at risk for identifying health problems and priorities
- Developing public policies to address local/national health issues and priorities
- Ensuring all populations have access to appropriate and cost-effective care that includes health promotion, disease prevention, and evaluation
Epidemiology and the Scientific Method
- Epidemiology utilizes the scientific method to describe and analyze health-related states or events
Scientific Method Components
- Appropriate study designs
- Statistical techniques for investigation and knowledge acquisition
- Identifying the health problem
- Developing hypotheses
- Statistical analysis
- Interpretation
- Dissemination of information
Study Designs in Epidemiology
- Descriptive epidemiology: Investigates who, what, when, and where via study designs
- Analytic epidemiology: Explores why and how via study designs
Importance of Descriptive Epidemiology
- Characterizes the distribution of health-related events and states
- Examines events based on person, place, time, and clinical criteria
Importance of Analytic Epidemiology
- Identifies and quantifies associations
- Tests hypotheses and supports causal statements
- Explains why and how health-related events occur
Selected Activities in Epidemiology
- Identifying risk factors for disease, injury, and death
- Describing the natural history of diseases
- Identifying those at highest risk of disease
- Identifying the greatest points of public health concern
- Monitoring health-related events over time
- Evaluating prevention and treatment programs' efficacy and effectiveness
- Providing information for health planning and decision-making
- Assisting in public health programs
- Acting as a resource person
- Communicating public health information
Selected Types of Epidemiologic Information
- Public health assessment
- Causes of disease
- Completing the clinical picture, or understanding the full scope of a condition
- Program evaluation, including efficacy (the ability to achieve a desired effect in those who participate in a program versus those who don't) and effectiveness (the ability to produce benefits in individuals who are offered the program)
Questions that Need Epidemiology
- Diagnosis: Myalgic encephalitis, prostate-specific antigen as a cancer test
- Causes: Stroke causes, obesity/metabolic syndrome
- Treatment: Best treatment options for specific conditions, surgical effectiveness
- Prognosis: Recurrence of heart attack/disease, prosthesis longevity
- Health Promotion & Protection: Harm of current school meals, effectiveness of public smoking bans
- Health and Disease Surveillance: International differences in suicide rates, future pandemics
- Health Inequalities: Why disparities in life expectancy exist between workers, effect of health services on health inequalities
Prevalence of Self-Reported Obesity (US Adults) via Map Data (2011, 2017)
- This is visual/map data providing regional trends in self-reported obesity in US adults from 2011 to 2017. Detailed values are visual, not in a text format.
