CHN C2-Triad Models Flashcards
This term refers to the occurrence and distribution of health such as disease, death, deformities or disabilities on human population.
Epidemiology
This term is Concerned with the study of probable factors that influence the development of these health conditions.
Epidemiology
It is Used to analyze the different factors that contribute to disease development.
epidemiology
This refers to inanimate or living organism that cause disease, they may be biologic, chemical,
physical, mechanical or nutritive, agent characteristics can be described in terms of virulence,
toxicity, intensity, impact or deficiency/excess.
Agent
This refers to any organism that harbors and provides nourishment for another organism.
Host
Host characteristics can be described in terms of their:
& influenced by:
susceptibility or resistance against effects of
a particular agent
demographic & biological factors along with personal habits
This term refers to immunologic experience
specific resistance
This results from intact skin and mucous membrane, good hygiene, reflexes like coughing.
Non-specific resistance
This represents the immunity and susceptibility levels of individuals comprising the population.
Herd immunity
This refers to the sum total of all external conditions and influences that affects life and development of an individual organism.
Environment
This Refers to the physical, biologic and sociological environments.
Environment
What are the practical applications of epidemiology?
1) Assessment of the health status of the community or community diagnosis.
2) Elucidations of the natural history of disease.
3) Determination of disease causation.
4) Prevention and control disease.
5) Monitoring and evaluation of health interventions.
6) Provision of evidence for policy formulation.
What are the Functions of the Epidemiology Nurse?
a) Implement public health surveillance.
b) Monitor local health personnel conducting disease surveillance.
c) Conduct and/or assist other health personnel in outbreak investigation.
d) Assist in the conduct of rapid surveys and surveillance during disasters.
e) Assist in the conduct of surveys, program evaluations, and other epidemiologic
studies.
f) Assist in the conduct of training course in epidemiology.
g) Assist the epidemiologist in preparing the annual report and financial plan.
h) Responsible for inventory and maintenance of epidemiology and surveillance unit
equipment.
TRUE OR FALSE
✓ Disease results from an imbalance between the disease agent and man as the host
✓ Nature and extent of imbalance depends upon nature and characteristics of agent and
host
✓ The characteristics of agent and host and their interactions are directly related to and
largely dependent on the nature of environment
TRUE TRUE TRUE
What are the Triad Models that explain MCT?
Wheel
Web
Ecological Triad
What model gives emphasis on the role of the genetic make-up of the host?
Wheel model
It is the inner core of wheel model
Host / genetic core
What core of wheel model represents the host’s characteristics like sex, age and behaviors?
Middle core
What core of wheel model represents the biologic, physical and social environment?
outer core
What model Depicts the intricate interrelationships of the various socio-demographic characteristics and behaviors of the host as well as the numerous environmental factors?
Web model
The web of causation of a disease refers to:
phenotype, behavior, environment, workplace, unknown factors, genes, micorbes
What model is developed to further the understanding of the dynamic interrelations among various personal and environmental factors?
Ecological triad
Ecological Triad includes:
Intrapersonal
Interpersonal processes and primary groups
Institutional Factors
Community Factors
Public Policy
This factor of ecological triad includes knowledge, attitudes, behavior, self-concept, skill, and developmental history.
Intrapersonal
This factor of ecological triad includes formal and informal social network and social support systems, including family, work group and friendship networks
interpersonal processes and primary groups
This factor of ecological triad includes social institutions and organization characteristics and formal (and informal) rules and regulations for operations
Institutional Factors
This factor of ecological triad includes relationships among organization, institutions, and informal networks with defined boundaries.
Community factors
This factor of ecological triad includes local, state, and national laws and policies
Public policy
The Epidemiologic Triangle consists of three component:
Host
Agent
Environment
This is a component of environment that is composed of the inanimate surrounding such as the
geophysical condition of the climate.
Physical environment
This is a component of environment that makes up the living things around us such as plants and
animal life.
biological environment
this is a component of environment which may be in the form of level of economic development of the community, presence of social disruptions and the like.
Socio-economic environment
What are the 3 components of environment?
Physical, Biological, Socio-economic environment
This model implies that each must be analyzed and understood for comprehensions and prediction of patterns of a disease.
Epidemiologic Triangle
This model refers to change in any of the component will alter an existing equilibrium to increase or decrease the frequency of the disease.
