Q

National Electronic Telecommunications System:

A

electronic reporting system used by state departments and CDC

23
Q

Why is the information reported by the local offices sometimes isn’t the best?

Reported by doctors’ offices and hospitals ( I think)

A

Some places could be busy to keep up with reporting, unfamiliar with reporting, patients recover before a diagnosis is confirmed, and don’t seek care.

24
Q

Mortality Statistics:

A

Most reliable
depends age, sex, race and ethnicity
Shifted from communicable to non-communicable

25
Q

Define Life expectancy

A

The average number of years a person from a specific cohort is projected to live from a given point in time
Compare health status for various populations

26
Q

When is life expectancy calculated?

A

birth, 65, and 75

27
Q

Which country has the highest life expectancy?

A

Japan (84 years)

28
Q

What are the shared traits of the longes-lived people?

A

Support system/social network
Eating wisely
Right outlook (stop to smell the roses)
Move naturally

29
Q

What is Health Adjusted Life expectancy?

A

The number of years of healthy life expected on average in a given population

30
Q

What are the 3 leading causes of death in America with age?

A

Heart Disease (>65)
Cancer (44-64)
Accidents (1-44)

Accidents: Unintentional, injuries, gun violence

31
Q

What did the 19th century suffer from?

A

Communicable diseases

32
Q

Why do women live longer than men?

A

More cardioprotective than men due to menopaue- estrogen
Better immune systems

33
Q

Infant Mortality

A

the number of deaths of children under 1 year old per every 1,000 live births; big indicator of the health status of a population

34
Q

Epizootic Rates

A

diseases that start in animals can sometimes transfer to humans and start outbreaks in human populations and tracking epizootic helps to determine the source of these diseases

35
Q

Prevalence vs Incidence Rates

A

when it comes to chronic diseases, prevalence rates are more useful than incidence rates because it is more important to know how many people are currently suffering from chronic diseases than it is to know in what time period they keep became afflicted

36
Q

What is secondary data useful for?

A

planning of public health projects and facilities

37
Q

US Census

A

Every 10 years; # of people, race, age, income, employment,, education, dwelling type, etc.

38
Q

Vital Statitics Report:

A

records of major life events → birth, deaths, marriage, divorce, and infant detah

39
Q

Which department takes care of Vital Statistics Report?

A

National Care for Health Statistics- Under CDC

40
Q

By who and how is data collected for the morbidity and mortality weekly report?

A

CDC
Data by state and region

41
Q

Why is self reported data not relibale

A

people tend to underreport bad health habits, overreport good health habits, and overall embellish their lifestyles to satisfy their egos!

42
Q

Descriptive Epidemiological Studies

A

the epidemiologist gathers data about the person, place, and time of the disease outbreak (who, when, and where?)

43
Q

What is the purpose of experimental studies:?

A

To find out the cause of disease, determine vaccine, drugs, etc

44
Q

What is the purpose of control varaible, use of tratement, control groups, randomization, and blinding?

A

Prevents biasness

45
Q

Randomization

A

random selection

46
Q

Blindings

A

process used in experimental research by which study participants, persons caring for the participants, persons providing the intervention, data collectors and data analysts are kept unaware of group assignment

47
Q

Double blindings

A

an experimental procedure in which neither the participant nor the experimenter are aware of which group (i.e., experimental or control) each participant belongs to.

48
Q

Intervention

A

more stuff added to the treatment

excercise

49
Q

What are the 4 national health surveys?
