The 4-year-old recruitment phase of the Women's Health Initiative sponsored by the National Institutes of Health is expected to end this month.
The initiative was launched with the ambitious goal of attracting 164500 women aged 50 to 79 years to participate in the largest government-sponsored study ever. As of October 31, 127528 women were enrolled. The study also is approaching its goal of recruiting 20% of participants from minority groups, with 21340 minority women enrolled. Goals of the study are to examine the effects of hormone replacement therapy, dietary change, and a combined calcium/vitamin D supplement on heart disease, cancers of the breast and colon, and osteoporosis.
