Media reports on the Women's Health Initiative (WHI) significantly impacted hormone therapy (HT) use in Australian women over 50. While HT use dropped sharply, it began to recover within two years, influenced by media coverage.

Area of Science:

  • Reproductive Health
  • Public Health Surveillance
  • Pharmacovigilance

Background:

  • The Women's Health Initiative (WHI) study results significantly altered perceptions and usage of hormone therapy (HT).
  • Understanding the long-term impact of major health reports on population-level treatment decisions is crucial for public health.
  • Continued surveillance of HT use is necessary to track trends and inform clinical practice.

Purpose of the Study:

  • To monitor Australian hormone therapy (HT) usage patterns.
  • To evaluate the influence of the Women's Health Initiative (WHI) findings and subsequent media coverage on HT utilization.
  • To assess HT use 16 months post-WHI report dissemination.

Main Methods:

  • Utilized data from the 2003 South Australian Health Omnibus Survey, a representative face-to-face interview survey.

  • Compared 2003 data with five previous surveys (1991-2000) using consistent methodologies.
  • Conducted 907 interviews with women aged over 40.

    • Main Results:

    • Current HT use in women over 50 decreased from 28% (2000) to 10.2% (2002) following WHI media reports.
    • By October 2003, HT use in this group recovered to 18.8%.
    • Media reporting was the primary factor influencing women's decisions regarding HT; half who restarted switched formulations.

    Conclusions:

    • Approximately 64% of HT users in 2002 discontinued therapy, largely due to WHI media reporting.
    • Nearly half of women who stopped HT in 2002 subsequently resumed therapy.
    • Media significantly shapes the utilization of hormonal therapies in the general population.
