What are the three health strategies for NCD?

What is the goal with primary prevention?
the goal is to protect healthy people from developing a disease or experiencing an injury in the first place
what are some examples of primary prevention? (5)
- education about good nutrition, regular exercise, dangers of tobacco, alcohol and other drugs
- proper seatbelt and helmet use
- regular exams and screening tests to monitor risk factors for illness
- controlling potential hazards at home and in the workplace
When does secondary prevention happen?
after an illness or serious risk factors have already been diagnosed.
What is the goal for secondary prevention?
The goal is to halt or slow the progress of disease (if possible) in its earliest stages
What are the goals in tertiary prevention? (4)
- slow disease progress
- maintain function
- lengthen life
- improve quality of life
What are some methods used tertiary prevention? (3)
- risk factor modification (weight loss)
- reducing harmful exposure
What is screening? (2)
- detects potential disease indicators
- indicates suspicion
What is diagnostic testing?
- detects the presence of a disease
- results in definitive diagnosis
Does early detection mean better outcome?
Define True positive.
The patient has the disease and the test is positive
Ideally, primary prevention will reduce the ______ and _______ of disease
incidence and prevalence
What are some examples of when screening is used? (5)

- colon cancer
- cervical cancer
- vision and hearing impairment
What is screening the first step to?
first step to diagnosis
Define false positive.
the patient does not have the disease but the test is positive.
Define True negative.
the patient does not have the disease and the is negative
Define False negative.
the patient has the disease but the test is negative
What is sensitivity?
probability that a test correctly classifies people with the disease as having the disease
What is specificity?
the probability that a test correctly classifies people without the disease as not having the disease.
What is positive predicted value?
the probability that someone who tests positive actually has the disease.
What is negative predicted value?
the probability that someone who tests negative actually does not have the disease
