Reply #31: I think it will relate to socioeconomic factors.

It wasn't just a few pounds. It was enough, based on BMI, to be a health risk.

I think in someways all women probably share some basic reasons for being overweight, but, there were specific factors relating to lesbians I found in the studies, namely:

socioeconomic status
education level
lack of education or information about good dietary habits
a past history of sexual abuse
discrimination

If you look at socioeconomic factors for example, women from lower socioeconomic levels have a higher obesity rate across the board.
