No, I specifically was referring to fat women. Check the recommendations on birth control pills--same thing, older + fat makes them risky. The problem with the big study is that their sample was disproportionately overweight.
Unopposed estrogen (i.e. the old estrogen only HRT) is bad for women of all sizes, endometrial cancer sucks.
Separately, obesity causes higher system estrogen levels and carries the same risks.
What you may be referring to is the more recent WHI study which does have methodological flaws, but unopposed estrogen is a no-no for patients with a uterus.
