Epidemiology | Midterm Set 5 Questions and Answers with
100% Correct Answers | Latest Version
Question 1.
the study of the distribution and determinants of disease frequency in human populations
and the application of this study to control health problems
Correct Answer: Epidemiology Definition
Question 2.
Key components of epidemiology
Correct Answer: - distribution
- determinants
- disease frequency
- application
Question 3.
2 fundamental assumptions of epi
Correct Answer: 1. human disease does not occur at random - there are factors
that increase or decrease likelihood
2. these factors can be identified through systematic investigation of
populations
Question 4.
1. Descriptive
2. Analytic/scientific
3. experimental (randomized controlled trial)
Correct Answer: Types of epi studies
Question 5.
describes disease patterns, no explicit comparison group, case reports/series, cross
sectional, ecologic, CANNOT identify causes of disease
Correct Answer: Descriptive
Question 6.
tests hypotheses about causes, compares groups systematically, clinical trials, cohort
studies, case-control studies
Correct Answer: Analytic/Scientific
Question 7.
1. Fixed
2. Dynamic *for fixed used cumulative incidence, for dynamic use incidence rate
, Correct Answer: Two types of populations
Question 8.
Fixed
Correct Answer: permanent (people born in 2003, veterans, trial participants,
etc.)
Question 9.
Dynamic
Correct Answer: transient (college students, can enter and exit, etc.)
Question 10.
4 Components of measuring disease frequency
Correct Answer: 1. population.
2. cases of disease - numerator
3. size of population - denominator
4. time
Question 11.
division of one number by another, do not need to be related (ratio of men to women
20/30)
Correct Answer: Ratio
Question 12.
division of 2 related numbers, numerator is part of the denominator (30 smokers out of
100 people total)
Correct Answer: Proportion
Question 13.
division of one number by another, time is the denominator (5 cases per 100
person-years)
Correct Answer: Rate
Question 14.
3 types of measures
Correct Answer: prevalence, cumulative incidence, incidence rate
Question 15.
measures the proportion of population with existing disease at a point in time prevalence
= existing cases at PIT / total population at PIT no units, 0-1, pop. is ALL, can make. %
Correct Answer: Prevalence
