    Author: Rigby AJ, Ma J, Stafford RS.
    Journal: Menopause; 2007; 14(5):853-8. PubMed ID: 17429334.
    Abstract:
    OBJECTIVE: Findings from the Women's Health Initiative (WHI) failed to confirm previous expectations about the net benefits of menopausal hormone therapy and have resulted in reduced use of these medications. The aim of this study was to evaluate women's awareness and knowledge concerning the risks and benefits of hormone therapy. DESIGN: A nationally representative survey was completed for a sample of 781 women (ages 40-60 y, mean 49 y) drawn from the Knowledge Networks Internet panel 24 months after publication of the first WHI findings, in June 2004. Responses were weighted to reflect the demographics of the US population. The main outcome measures were awareness of WHI and knowledge of its findings. An aggregate score was constructed to assess women's knowledge of the impact of hormone therapy on seven key disease outcomes. Logistic regression determined the independent predictors of (1) WHI awareness and (2) a positive aggregate knowledge score, reflecting appropriate responses about risks and benefits. RESULTS: Only 29% of women were aware of the WHI results. Only 40% of women had a positive aggregate knowledge score. Aside from awareness of WHI and independent of other factors, knowledge scores were lower for African American women (odds ratio, 0.4; 95% CI: 0.2-0.6) and among women with less education (odds ratio, 0.5; 95% CI: 0.3-0.9). Knowledge was greatest for breast cancer and osteoporosis outcomes and most limited for colorectal cancer and memory loss. CONCLUSION: Surveyed women had limited awareness and knowledge of the WHI results, suggesting limited diffusion. Targeting younger, less educated, and African American women is warranted.
