Part 1: Select the study design type that best matches each scenario (1 point each).
Options (some will be used more than once):
Cross-sectional
Cohort
Case-Control
RCT/Experimental
Meta-Analysis
Systematic Review
Qualitative
1. You survey 595 adults age 35-50 and ask them how often they currently consume fruit juice
(Never, <1x/week, 2-4x/week, 5-7x/week, >1 per day). You also ask them whether they have
been diagnosed with T2DM. You compare the rates of having T2DM between the highest and
lowest fruit juice consumption groups.
Study Design:
2. You perform a PubMed search for articles related to child diet + diabetes. This search returns
3666 results, of which you determine that 9 studies relate to your research question and contain
appropriate data. After combining the results of these studies, you find that there is a 12%
increase in the risk of T2DM in individuals who consumed more than 2 sugar-sweetened
beverages (soda, juice, etc.) a week during childhood.
Study Design:
3. You randomly assign 100 students to either receive an exercise intervention (50 students) or to
receive only an educational brochure. Over the next six months, you measure how many
students in each group report symptoms of cold, flu, or COVID to see if there are immune
differences between the groups.
