Solution:
Interpretation of “Odds Ratio” (OR) :
OR = 1.0; OR = 0.5; OR = 2.0
Odds ratio can effectively measure the “association between frequency of exposure and health outcome” in statistically significant sample.
Hence when OR = 1.0, it denotes that “absence of any association” among the exposure and disease incidence/health outcome.
When OR = 0.5, it signifies that the “exposure is actually having a protective effect” on health outcome/disease incidence.
When OR = 2.0, Value above 1.0 indicates “positive association existing between disease incidence/health outcome and the exposure”. The OR value 2.0 denotes the disease incidence/health outcome will be twice higher in exposed individuals.
A.
OR=+0.6 for relationship between low fat diet-colon cancer
OR = 0.6, For values less than 1 and above 0.5 it signifies that the “exposure is actually having a protective effect” on health outcome/disease incidence.
B.
OR = +1 for relationship between aerobic exercise -dental caries
when OR = 1.0, it denotes that “absence of any association” between the exposure and disease incidence/health outcome
C.
OR = +1.3 for relationship between exposure to passive cigarette smoking -lung cancer
OR = 1.3, Value above 1.0 indicates “positive association existing between disease incidence/health outcome and the exposure
D.
OR = +3.0 for relationship between pelvis infectious disease- ectopic pregnancy
OR = 3.0, Value above 1.0 indicates “positive association existing between disease incidence/health outcome and the exposure”.
