Women invited to participate in UI study on menopausal hot flashes

IOWA CITY, Iowa -- Women age 45 and older who experience hot flashes every day are invited to participate in a University of Iowa research study on menopausal hot flashes.

The study will test the effectiveness of phytoestrogen, a plant-based dietary supplement with estrogen-like activity, in preventing hot flashes. Many common plants -- such as alfalfa, barley, carrot, oat, parsley, red bean, rice, sesame, soybean and wheat -- contain phytoestrogens. The UI study will involve phytoestrogens made from red clover extracts.

The 14-week study will require three visits to the clinic in Iowa City. Participants will be randomly assigned to receive one or two doses of either the dietary supplement or a placebo (inactive pill).

To qualify, women must be:
-- age 45 to 60;
-- menopausal, with no menstrual period for at least six months;
-- having hot flashes and/or night sweats every day;
-- not currently taking hormone replacement therapy.

Women who are vegetarian will not qualify for the study.
