Study Notes
Public Health Overview
- Focuses on community population health.
- Core functions of public health include assessment, policy development, and assurance.
Lillian Wald and Henry Street Settlement
- Lillian Wald founded the Henry Street Settlement to provide social and health services to the immigrant community in New York City.
Health Promotion and Risk Reduction
- Interpretation of lab values is critical for health assessments, including lipid panels.
- High LDL and cholesterol levels necessitate dietary changes and health recommendations.
- Emphasis on lifestyle adjustments including diet modification.
Dietary Changes
- DASH diet promotes heart health by emphasizing whole foods and reduced sodium.
- For diabetes, weight loss and reducing simple carbohydrates are vital.
- Trans fats elevate LDL and diminish HDL cholesterol, while saturated fats increase both.
- Omega-3 fatty acids are healthier alternatives to avoid trans fats.
Epidemiology Concepts
- Descriptive epidemiology (who) vs analytic epidemiology (why and how).
- Transition from infectious diseases to chronic illnesses occurred post-1950s with advancements in antibiotics and vaccines.
- Definitions of disease spread:
- Sporadic: occasional cases.
- Endemic: consistent presence in a particular area.
- Epidemic: sudden increase above expected levels.
- Pandemic: widespread across regions.
Social Determinants of Health
- Socioeconomic status is the most significant predictor of health outcomes.
Prevalence and Incidence
- Prevalence: Total number of existing cases within a specific population at a given time.
- Incidence: Number of new cases in a population during a specific time frame.
Epidemiological Measures
- Positive Predictive Value: Reflects disease presence in a community.
- Attack Rates: Proportion of exposed individuals who contract the disease.
- Case Fatality Rate: Ratio of deaths to total cases during a specific time, indicating disease severity.
Epidemiological Triangle
- Consists of three components: agent, host, and environment.
- The triangle is used to understand disease transmission and to implement prevention strategies.
Natural Life History of Disease
- Investigates the onset, spread, latency, and infectious periods of a disease, e.g., HIV.
Community/Herd Immunity
- Aim for 90-95% vaccination coverage to ensure herd immunity and control outbreaks.
Sensitivity and Specificity
- Sensitivity measures true positive rate; specificity measures true negative rate.
- High sensitivity and specificity reduce false positives/negatives, e.g., flu tests typically have 70% specificity.
Causality and Environmental Health
- Strong evidence links smoking with lung cancer drawn from extensive epidemiological studies.
- Pesticides and toxic substances pose risks, especially for vulnerable populations like children and pregnant women.
Environmental Health Considerations
- Children, elderly, and pregnant women are at highest risk for environmental hazards due to physiological factors.
- It's essential to take thorough environmental histories to identify potential exposures.
Surveillance in Public Health
- Involves outbreak investigations and various types of surveillance:
- Active Surveillance: Public health workers actively seek disease cases, which can be costly.
- Passive Surveillance: Relies on routine data collection and reporting.
- Sentinel Surveillance: Monitors select groups, may not reflect the broader population.
Foodborne Illnesses
- Highest risk demographics include children under 5, immunocompromised individuals, older adults, and pregnant women.
- Special considerations are needed for each group's vulnerability to foodborne pathogens.
