Thanks - this works perfectly to give both scalars and variables. I appreciate your help!

doesn't seem to need a loop at all.

Nevertheless, you want scalars, although I am not clear why.

You can have it both ways by having variables and scalars too.
(The variables will come in useful for graphs and tables.)

egen cases = sum(dflag), by(year)
egen n = sum(1), by(year)
gen prevalence = cases / n
tabdisp year, c(prevalence)

levelsof year, local(Y)
foreach y of local Y {
        su prev if year == `y', meanonly
        scalar prev`y' = r(min)
