1. Q: What is mortality?
A: The number of deaths in a population.
1
, • Rationale: Mortality is a key demographic and epidemiological metric used to measure
the frequency of deaths in a specific population during a designated timeframe. It is
typically expressed as a rate (e.g., deaths per 1,000 or 100,000 individuals) and helps
public health officials evaluate the overall health status, life expectancy, and major lethal
threats within a community.
2. Q: What is morbidity?
A: The number of illnesses or disease cases in a population.
• Rationale: Morbidity refers to the state of being symptomatic, diseased, or unhealthy
due to a specific medical condition. Unlike mortality (which tracks death), morbidity
captures the burden of disease, disability, and chronic illness within a community, usually
measured via incidence (new cases) or prevalence (existing cases).
3. Q: What are health determinants?
A: Conditions like housing, transportation, education, and jobs.
• Rationale: Health determinants represent the broad array of personal, social, economic,
and environmental factors that combine to dictate the health status of individuals or
populations. These are non-medical factors—often referred to as Social Determinants of
Health (SDOH)—that heavily influence health outcomes before a patient ever sets foot in
a clinic.
4. Q: What is an intervention?
A: An action designed to improve a health problem.
• Rationale: In public health, an intervention is any strategic activity, policy, program, or
treatment executed with the intent of altering a behavior or environmental factor to
improve health outcomes. Interventions can range from individual clinical counseling to
structural level initiatives, such as community-wide water fluoridation.
5. Q: What does the PRECEDE-PROCEED model help with?
A: Planning, implementing, and evaluating health programs.
2
, • Rationale: Developed by Green and Kreuter, the PRECEDE-PROCEED framework is
a comprehensive structure for designing public health programs. It works backward from
desired health outcomes to identify contributing behavioral and environmental causes
(PRECEDE phases), followed by the strategic implementation and structured evaluation
of targeted interventions (PROCEED phases).
6. Q: What is the socio-ecological model?
A: A framework showing how individual, social, community, and policy factors influence
health.
• Rationale: The socio-ecological model emphasizes that health outcomes are not driven
solely by personal choices. Instead, it illustrates that an individual's health behaviors are
deeply nested within a complex dynamic of overlapping ecosystems: interpersonal
relationships, organizational environments, community norms, and overarching public
policies.
7. Q: What are individual factors included in the socio-ecological model?
A: Influences on an individual's behaviors that can affect their choices (e.g., knowledge,
attitudes, beliefs).
• Rationale: The individual (or intrapersonal) level is the core of the socio-ecological
model. It encompasses personal characteristics such as biological traits, genetics,
personal history, age, literacy, and psychological attributes that govern how an individual
processes health information and acts upon it.
8. Q: What are interpersonal factors included in the socio-ecological
model?
A: Interactions with others that provide relationships and social support.
• Rationale: The interpersonal tier focuses on the immediate social circle that surrounds
an individual. This includes family units, peer networks, friends, roommates, and co-
workers. These relationships establish social norms, provide emotional and economic
support, and significantly mold personal health habits through peer influence.
