concept of health and disease Flashcards
(70 cards)
a state of complete physical, mental and social well being and not merely the absence of disease or infirmity
health
- by WHO, 1946
positive, dynamic process of realizing one’s full physical, mental, emotional and spiritual potential
wellness
true or false:
health and wellness is often used interchangeably
true
(both mean a state of being free from disease and body malfunction)
briefly explain health and wellness
wellness - ongoing practices
health - overall condition
Health = Your overall condition
— if your body and mind are working well, you’re healthy.
Wellness = Your daily habits
— the things you do regularly to stay healthy (like eating well, exercising, sleeping enough).
[Health is the goal
(being free from illness).
Wellness is the journey
(the choices you make to reach and keep that goal).]
briefly explain the social model of health
(bottom to top)
individual
- fixed factors like age, genetic, sex
individual lifestyle factors
- smoking
- poor diet
- inactivity
social and community networks
- small networks
living and working conditions
- stressful job
- poor housing
- low healthcare
general socioeconomic, cultural and environmental conditions
- pollution
- weak support
- smoking norm
who made the Social Model of Health
Dahlgren & Whitehead, 1991
briefly explain the dimensions of good health
Intellectual
- Ability to solve problems, think critically, and handle stress
- Example: Practicing meditation helps lessen exam anxiety
Environmental
- Reducing risks and coexisting peacefully with nature
- Example: Taking part in neighborhood cleanup campaigns
Financial
- Managing resources for financial stability
- Example: Setting aside money for unforeseen medical emergencies
Physical
- Diet, exercise, and abstaining from bad behaviors
- Example: Jogging for 30 minutes every day
Emotional
- Emotional awareness and control
- Example: Going to treatment to deal with bereavement
Spiritual
- Connectivity to meaning, purpose, and values
- Example: Partaking in spiritual activities such as meditation or prayer
Personal experience of feeling unwell (mental, physical, or spiritual
discomfort)
illness
A biological problem in the body, diagnosed based on medical theory.
disease
The social role and response society gives to someone who is ill.
sickness
[Sickness is how society sees and reacts to a person being ill.
It’s about the social role a sick person takes — like staying home, resting, or going to the doctor — and how others treat them differently because they are sick.
illness is what you feel
disease is what the doctor finds
sickness is how others respond to your condition]
briefly explain the concepts of illness and disease
(diagram -transes)
illness
- individual
- “i feel ill”
sickness
- community
- “you look sick”
disease
- doctor
- “u have a disease”
it happens when the body’s normal function is distributed due to an interaction between the host (person), agent (like bacteria or virus) and environment (surrounding)
disease
how is disease prevention possible
by identifyinng and managing these factors
Disease means discomfort or difficulty in moving freely, often caused by environmental, internal, or external agents.
Dictionary Definition
A pathological condition when the body deviates from its normal functions. Illness is the personal feeling of being unwell; sickness is the public/social recognition of that condition.
Medical Definition
Disease is caused by poor adjustment between humans and the environment, emphasizing the need for clean air, safe water, and a healthy ecosystem.
Ecological Definition
briefly explain the historical theories of disease causation
Supernatural and Karma
- illness was once believed to be punishment for bad deeds or caused by supernatural forces
Theory of Humors
- health depends on the balance of 4 body fluids (blood, phlegm, black bile, yellow bile); imbalance leads to disease
Miasmatic Theory
- diseases like malaria were thought to be caused by bad air (miasma) from decaying matter
Germ Theory
- diseases are caused by microorganisms
- proven by scientists like Louis Pasteur and
Robert Koch
Theory of Contagion
- spread through direct or indirect contact with infected people or objects
briefly explain the epidemiological triad
host
agent
environment
- disease occurs due to interaction
between the agent, host, and environment, often needing a vector (like mosquitoes in malaria).
*Multi-factorial Causation
- some diseases, like heart disease, are caused by multiple factors (lifestyle, environment, genetics).
diseases often develop through a complex series of causes, not
just one simple factor
web of causation
(image)
[illnesses come from a mix of causes, can be internal or external.
the term “web” shows how all these causes are connected :
example:
Internal:
Genes – inherited traits that may increase risk for certain diseases
Immune response – how well your body fights off illness
Lifestyle – eating, sleeping, and exercise habits
Psychological factors – stress, anxiety, or mental health issues |
External:
Trauma and accidents – injuries that lead to health problems
Noise pollution – constant loud sounds that affect mental or physical health
Toxins in air, food, water – exposure to harmful chemicals
UV rays, weather, climate – can affect skin and overall health
Urban designs – crowded or unsafe environments
Workplace hazards – dangerous conditions in jobs
Pathogens – viruses, bacteria that cause infections
Interactions with humans – social contact or isolation
Healthcare interventions – treatments can help or cause side effects |
briefly explain the 2 categories of diseases
infectious disease:
- caused by pathogens
- spread through air, food, water or direct contact
- ex: Influenza, Malaria, AIDS
chronic disease:
- long term
- caused by multiple factors like genes, lifestyle, environment
- ex: Diabetes, Asthma, Heart Disease
briefly explain the concept of disease prevention
Primordial Prevention:
- prevent the development of risk factors early through
health education
lifestyle changes,
nutrition
Specific Prevention:
- immunizations
- nutritional supplements
- environmental pollution control
- product safety standards
what are the components of the healthcare system
(image)
by WHO:
system building blocks
- service delivery
- health workforce
- health information systems
- access to essential medicines
- financing
- leadership and governance
(access coverage and quality safety) =
- improved health (level and equity)
- responsiveness
- social and financial risk protection
- improved efficiency
An individual or organization licensed to provide health care services.
healthcare provider
- according to National Cancer Institute (n.d.)
- they are public servants who attend to the needs of the people and the community
what is the primary role of healthcare providers
rendering healthcare services
