This study and most similar do not take into account bone density, this is a concern for women who have to actively build this up early in life to have a reserve (to account for the continual decline after about age 25 that is worse for women) to stave off osteoporosis - as well as continually work on maintenance after that with weight bearing/resistance exercise and diet. At least this is what I learned from my exercise and physiology textbook, the best antidote is building up of bone density in a woman's younger years and I doubt there's research into a substitute for that.
