WHI, Five Years Later–WHY no Change

The Women’s Health Initiative (WHI) Estrogen plus Progestin (E plus P) trial was prematurely stopped because it caused harm (1). Until the Estrogen in women with hysterectomy arm (E only) of the WHI was also halted prematurely in 2004 (2), progestin was blamed for the lack of heart disease prevention. But now, five years later, doctors and media are still discussing Hormone Replacement Therapy (HRT) and menopause as estrogen deficiency. The fundamental question is: Given these huge, great science WHI studies showing harm is caused by HRT, why has medicine not changed?

Estrogen Deficiency: The Wrong Idea About Menopause

The largest and best-controlled trial testing whether hormone “replacement” therapy prevented heart disease was stopped three years early in July 2002. The Women’s Heath Initiative (WHI) study included over 16,600 healthy menopausal women without symptoms. These women were randomized to daily conjugated equine estrogen (Premarin, 0.625 mg) plus medroxyprogesterone (Provera, 2.5 mg) or an identical placebo. Hormone therapy increased breast cancer significantly (by 26% over placebo) and caused higher rates of heart attacks (29%), strokes (41%) and blood clots (211%). These risks outweighed this therapy’s significant benefits in preventing osteoporotic fractures of the hip (decreased by 34%) and colon cancer (decreased by 36%).
Since July 2002,hundreds of talk shows and editorials across North America have discussed these results. Many doctors and medical groups have offered criticisms. However, no one has yet identified what I believe is most important.
