week 2 Flashcards
what is epidemiology
- method used to find cause health outcomes and disease in population
- with the information gathered scientists and health professional can best inform specific population on ways in which they can prevent and control health problem
non experimental observational studies
in observation studies the reseacher observes and systematically collect information but does not try to change people by observing
Experimental
One or more variables are manipulated by the researcher subjects are randomly
assigned to different treatment levels (random assignment), and the results of the treatments on outcomes are observed.
Experimental randomized
In randomized control trials , the patient are randomly assigned to different groups, The resulting effect estimate is the difference between the mean response in the two groups
Experimental non randomized
A clinical trial in which participants are not assigned by chance to different treatment groups. Participants may choose which group they want to be in or may be assigned too by the researcher
what is the sloth model
Outline the sloth model in relation to PA domains and give examples of how PA level can vary within this model
Examine and discuss physical activity patterns among various population
sleep
For optimal daily functioning, the following recommendations:
9.11 hours/night of uninterrupted sleep (ages 5.13 years)
8.10 hours/night of uninterrupted sleep (ages 14.17 years)
leisure time
-Work hard play hard
-Leisure time domain is where general public is more likely to engage
Physical activity epidemiology
Study and analysis of the frequency and distribution of PA in a defined population
Helps to identify:
Patterns of PA behaviour
Predictors (Determinants) of PA behaviour
Individual, interpersonal, social, environmental factors The determinants of health
