Q

When new cases occur rapidly over a short period of time in a well-defined population, the incidence rate is referred to as….
Also called as the cumulative incidence rate
In usual, the rate base for attack rate is 100
EX) On June 20, 2017, the cases of diarrhea were reported to the District Health Officer in Stillwater, OK. The illness placed soon after eating contaminated food at a high-school picnic. Attack rates were calculated for each of the foods, with the highest attack rate for cholate cake. Of those who ate the cholate cake, 52 were ill and 8 were not ill, yielding an attack rate of 87%

Q

• What is “Health”? How would you define it?
o The definition of health has changed over time
• Different things to different people
• It is now considered a multidimensional concept that includes:
• -Physical, emotional, social, mental and environmental aspects

26
Q
  1. Educational Approach:
    • The most effective mean for achievement of changes in the health practices and lifestyles of the community
    • In general, outcomes are slow but permanent and enduring
    • Sufficient time should be allowed for the individual to bring about the desired changes in his/her behavior
    • Components
    o Communication
    o Motivation
    o Decision-making
  2. Primary Health Care Approach:
    • This is about caring for people, rather than simply treating specific diseases or conditions - community participation
    • It provides comprehensive, accessible, community-based care that meets the health needs of individuals throughout their life
    • This includes a spectrum of services from prevention (i.e., vaccinations and family planning) to management of chronic health conditions
  3. Administrative/ Service Approach:
    • Intend to provide all the health facilities and services to the people as needed
    • It becomes a failure if the service is not based on the needs of the people
  4. Legal/Regulatory Approach:
    • Government makes laws and regulations to protect the health of the community
    o Examples of Common Public Health Laws
    o Mandatory vaccinations
    o Addressing social welfare through retirement benefits and health insurance
    o Required proof of safety
    o Promoting improvements and expansions of healthcare infrastructure
    o Required environmental impact studies prior to initiating new program

Q
  1. Credibility:
    • The degree to which the message is perceived as trustworthy by the receiver
    • It should be scientifically proven, based on facts
    • It should be compatible with local culture and goals
  2. Interest:
    • If the health education topic is of interest to the people, they will listen to it
    • Health educator should identify the “felt needs” of the people and then prepare a program based on the needs (e.g., needs assessment)
  3. Participation:
    • Health educator should encourage people to participate in the program
    • Once the people are given a chance to take part in the program, it leads to their acceptance of the program
    • Methods like a lecture, symposium, conference, group discussion, panel discussion, etc. provide opportunity for people’s participation
  4. Motivation:
    • “The fundamental desire for learning/doing something of an individual”
    • Motivation should be relevant to individual’s needs and desire
    o Ex) for a teenager, appearance might be a motive to take care of his body weight whereas for an adult, it can be the healthy life
  5. Comprehension:
    • Level of understanding of the people who receive the health education
    • Should first determine the level of literacy and understanding of the audience
    • Words that are strange or new to the people should not be used
    o Ex) Instead of saying “Exercise at least 30 minutes of moderate to vigorous intensity aerobic activity”, a better way of explaining would be “Walk 7,500 steps/day for health benefits
  6. Reinforcement:
    • This is the principle that refers to the repetition needed in health education
    • It is not possible for the people to learn new things in a short period of time
    • So repetition is a good idea
    • This can be done at regular intervals and it helps people to understand new ideas or practice better
  7. Learning by Doing:
    • If the learning process is accompanied by doing new things, it is better instilled in the minds of people
    “If I hear, I forget
    If I see, I remember
    If I do, I know”
  8. Known to Unknown:
    • Before the start of any health education program, the health educator should find out how much the people already know and then give them the new knowledge

• The existing knowledge of the people can be used as the basic step up on which new knowledge can be placed
9. Setting an Example:
• The health educator should follow what (s)he preaches
• (S)He should set an example to others to follow
10. Good Human Relations:
• The health educator should have good personality and should be able to maintain friendly relations with the people
• The health educator should have a kind and sympathetic attitude toward the people and should always be helpful to them in clarifying doubts or repeating what is not understood
11. Feedback:
• For any program to be successful, it is necessary to collect feedback to find out if any modifications are needed to make the program more effective
12. Community Leaders:
• Community leaders can be used to reach the people of the community and to convince them about the need for health education
• Leaders can also be used to educate the people as they already have a good relationship with the people of their community
• The leaders may have an understanding of the needs of the community
13. Soil, Seed, Sower:
• Soil is “the community”
• Seed is “information”
• Sower is “the person giving the information – Health Educator”

A

Q

What are the definition of community?

A

Traditional - Four possibilities:
• Functional spatial units meeting basic needs for sustenance
• Units of patterned social interaction
• Symbolic units of collective identity
• Political action unit to make change
Community Definition: Health Research/ Community Health
1.)A geographic area with specific boundaries (e.g. a neighborhood, city, county, state)
2. A group of people who have common characteristics (e.g., location, race, ethnicity, age, occupation, interest in particular problems or outcomes, or common issues)

Q

Incidence and prevalence measure different aspects of disease occurrence
Prevalence Incidence
Numerator: All cases, no matter how long diseased Only NEW cases
Denominator: In general, all persons in population Only persons at risk of disease
Measures: Presence of disease Risk of disease
Most useful: Resource allocation; the burden of chronic disease Risk, etiology; study of causation

A

Compare incidence vs. prevalence

  4. ) Individual & Lifestyle Factors: Diet, Physical activity, Alcohol, cigarette, drug use, Hand washing
  5. ) Biology & Genetics: Age, sex, HIV status, Family History of Heart Disease/Health
A

What are the concepts of determinants of health?

45
Q

1.) Informing people
• Increase individual’s awareness
o People are informed about the different diseases, their etiology and how to prevent them
2.) Motivating people
• Concerned with clarifying/ changing attitudes, beliefs, values and/or opinions
• After health information is given, it is necessary to motivate them change their lifestyles so that becomes favorable to promoting health and preventing disease
• Motivation is defined as “a combination of forces that initiate, direct, and sustain behavior”
3.) Guiding into action
• Concerned with development of skills and action
• A person who has obtained health information might be motivated to change his/her behavior and lifestyle
• He/she might need professional help and guidance so as to bring about these changes and to sustain these altered lifestyles
