Stata of course is just following your instructions here!

The outer loop over 4/4 serves no purpose here.

In essence you have

foreach j in health married hispanic college  {
     ttest `j' if (sample4 ==1), by(treatment) unequal }

and you want to add informative text. One example is

foreach j in health married hispanic college  {
     di "`j'"  _n
     ttest `j' if (sample4 ==1), by(treatment) unequal }

and you can add whatever decoration you want

foreach j in health married hispanic college  {
     di "{title:`j'}"  _n
     ttest `j' if (sample4 ==1), by(treatment) unequal }

See the help for -display- and for -smcl-.

Stata just does one test after another after another but doesn't label. I guess I can go through the order of the variables but would be nice if it was clearly labelled. I've had a look through the help guide but can't find a way to do this. I've included just a few variables here but I wish to run this for many and so it's difficult to identify which variables are in which test otherwise.
