Question
Part 1. Name the study design that is described and list ONE strength, ONE limitation, and ONE measure of either frequency OR comparison that could be used in the analysis for the given study design.
1. One or more groups of people are identified based on exposure and followed over time to assess differences in the frequency of a health outcome and determine the relationship between the exposure and the outcome
2. Researcher manipulates the exposure, assigning participants to exposed and unexposed groups, following them over time to assess differences in the frequency of a health outcome and determine the relationship between the exposure and the outcome
3. Compares people with a health outcome to those who do not have the health outcome and looks back retrospectively to compare how frequently the exposure to a risk factor is present in each group to determine the relationship between the risk factor and the disease.
4. Data on existing exposures and health outcomes collected from a population at a single point in time.
Explanation / Answer
Name of study - Exposure vs Health : Strength, Limitation and Comparison
Strength - The main strength of this study is to assess differences in the frequency of a health outcome .
Also determining the relationship between the exposure and the outcome.
Limitation:-We have only exposed and unexposed groups to compare and, following them over time to assess differences in the frequency of a health outcome
ONE measure of either frequency OR comparison:-
Compares people with a health outcome to those who do not have the health outcome.
Also compare how frequently the exposure to a risk factor is present in each group to determine the relationship between the risk factor and the disease.
