Hormone therapy falls short in new aging study

Older women on hormone replacement therapy may not gain any protection from disability as they age. That's despite some hopeful hints from early research. Scientists have speculated that waning estrogen levels may contribute to muscle loss and other declines in physical function as women age.

Hormone replacement therapy was thought to give women better physical functioning as they age compared with women who never took hormones. But this current study in the journal Menopause suggests this is not the case.

The findings are based on a subgroup of women who had taken part in the women's health initiative study. It was halted in 2002 when researchers found that women on HRT had higher risks of heart attack, stroke breast cancer and blood clots.
