I mean we did two separate studies several years apart, but so many subjects participated in both studies that I can't just lump all the data together, since I expect that the repeated scans from the same subject would violate some sort of sphericity assumption.

The other variables that we're interested in testing are mostly things like average minutes of moderate / vigorous physical activity per day, which we collected in both studies.
