LECTURE 5 EPIDEMIOLOGY EXAM
QUESTIONS AND ANSWERS
ANSWER-The type of descriptive study that the objective is to describe the experience
of a single case or a group of cases (person, place, time)
Association present - ANSWER-Interpretation of Ratio Measure ">1 and <1"
RCT and Community Trial - ANSWER-Types of experimental analytic study
Case study/cases series, ecologic study, describing person place and time - ANSWER-
Examine existing facts and hypothesis
Cross sectional study and case control study - ANSWER-Formulate new and more
specific hypothesis
Cohort - ANSWER-It obtain additional facts to test acceptability of new hypothesis
Experimental - ANSWER-Evaluate new evidence and draw conclusions
Intervention group - ANSWER-What are exposed in intervention study?
Control group - ANSWER-What are unexposed in intervention study?
Exposed and unexposed - ANSWER-What are the two groups in study population in
which has free outcome in intervention study?
To show that the probability of outcome (-) disease is less in intervention than the
control group - ANSWER-Objective of the intervention study
To show that the proportion of those with disease is greater in exposed than the
unexposed - ANSWER-Objective of cross sectional study
Defined population (one group) - ANSWER-What kind of study population has cross-
sectional study have?
Observational ((-) manipulation of E) - ANSWER-It is also classification of cross-
sectional
Analytic - ANSWER-It is a classification of cross-sectional which test hypothesis based
on the coexistence of both factor and outcome
Analytic, observational, retrospective, and longitudinal - ANSWER-Classification of case
control study
