Changing use of hormone therapy among minority women since the Women's Health Initiative

OBJECTIVE: There has been a significant shift in the use of hormone therapy (HT) among nonminority women since the publication of results of the Women's Health Initiative (WHI). Little is known about how the WHI results affected minority populations. This survey measured patterns of HT use among inner city women after publication of the WHI results, identified factors involved in the decision to continue or discontinue HT, and characterized the symptom burden and the experience of women who attempted to discontinue HT. DESIGN: We conducted a cross-sectional survey of 101 English- and Spanish-speaking women in an inner city general internal medicine clinic from August 2003 to April 2004. All women had been taking HT at the time of the publication of the WHI results. The survey included questions on patient-reported experience with HT, symptoms of menopause, and use of alternative treatments. RESULTS: Overall, 101 of 142 (71%) eligible women agreed to participate. The mean age of participants was 60 years; 43% were African American and 46% were Hispanic. The mean duration of HT use was 9.6 years. Three quarters (74%) had heard about the WHI findings, and 87% had attempted to stop taking HT after their publication. The most common reason for attempting to stop HT was concern about an increased risk of cancer or a general increase in risk to health. Of those who stopped HT, the vast majority (85%) reported vasomotor symptoms, and 26% restarted HT, mostly to treat those symptoms. CONCLUSIONS: Nearly all minority women in this small sample attempted to stop HT use after the results of the WHI were published. Restarting HT for treatment of symptoms was common.     

Personal use of hormone therapy by postmenopausal women doctors and male doctors' wives in Italy after the publication of WHI trial

OBJECTIVE: To describe the prevalence of hormone replacement therapy (HT) use by postmenopausal women doctors and doctors' wives in Italy and to explore the relationship between their personal characteristics and HT use. DESIGN: A total of 500 women doctors and 500 men doctors answering on behalf of their female partners were interviewed by a specialised company in the first months of 2003. Questions were meant to explore medical, behavioural and professional characteristics, personal use of HT, reasons for or against HT use and side effects of HT. The distribution of doctors' specialisation (general practitioners (GPs), gynaecologists, medical oncologists) in the sample interviewed was the same as that of the Italian medical community. RESULTS: Overall, 37% of women doctors and 39% of doctors' wives had ever used HT after menopause, of which 64 and 58%, respectively, were current users. The median duration of HT in the past users was 2.7 years for women doctors and 3.7 for doctors' wives. There were wide differences of HT use according to the type of specialisation: gynaecologists were more willing to use HT (56-59%) than GPs (30-31%) or medical oncologists (16-30%).Vasomotor symptoms (68-69%), followed by the prevention of osteoporosis (28-39%), were the main reasons for commencing HT. The main reasons not to take or to stop HT were the absence or resolution of menopausal symptoms. Only 8% of women doctors and 4% doctors' wives stopped HT after the publication of the WHI data. CONCLUSIONS: In Italy, women doctors/doctors' wives personally use HT much more than postmenopausal general population.     

The Women’s Health Initiative Conundrum

Summary The WHI has been designed to evaluate the metabolic risks and benefits of Estrogen/Progestagen Therapy (HT) or Estrogen Therapy (ET) in women in their later postmenopause. It has not been designed to study the effect of HT or ET on symptomatic peri- and early postmenopausal women. Furthermore, the selection criteria used in the WHI are not congruent with the profiles of women treated in daily medicine by HT/ET: women starting HT/ET in clinical routine are younger, less obese and healthier than the WHI population. Therefore, the results and the risk-benefit-conclusions of the WHI cannot be applied to normal symptomatic peri- and immediately postmenopausal women, and even less to women with early (40–50 years) or premature (40yrs.) menopause.     

Recent reversal of trends in hormone therapy use in a European population

OBJECTIVE: The impact of the Women's Health Initiative (WHI) randomized trial results published in July 2002 indicating that hormone therapy (HT) is potentially harmful for the heart and the mammary gland of naturally postmenopausal women was assessed for the first time in a European population. DESIGN: This study continuously monitored HT use from 1994 through 2003 in a population-based random sample of 5,758 women aged 35 to 74 years residing in Geneva (city and canton), Switzerland, yielding 1,938 naturally postmenopausal women with an intact uterus and 206 artificially postmenopausal women. Women in the former subgroup weighed substantially less than their WHI trial counterparts but were not otherwise at lower risk for cardiovascular disease. RESULTS: Among the naturally postmenopausal women with an intact uterus, current HT use increased from 29% to 46% (P < 0.0001) through July 2002 and then decreased abruptly to 31% in 2003. Current HT use remained stable (range, 38%-46%; trend P = 0.92) among the artificially postmenopausal women. CONCLUSIONS: Successive annual increases from 1994 through 2001 in the prevalence of current HT use by postmenopausal women living in Geneva were dramatically reversed to the level in 1994 just after the results of the WHI trial were published, but only for naturally postmenopausal women with an intact uterus. Approximately one in three of the latter women who stopped using HT may also have lost its beneficial effects on bone health.     

Breast and ovarian cancer screening of non-carriers from BRCA1/2 mutation-positive families: 2-year follow-up of cohorts from France and Quebec

We described and compared breast and ovarian screening practices in the 2-year period following test result disclosure in female non-carriers from BRCA1/2 mutation-positive families living in two countries, France and Quebec, Canada, which provide universal health care. Four hundred and two (France n=293; Quebec n=109) unaffected female non-carriers from BRCA-proven mutation families provided information about the uptake of mammography, clinical breast examination, breast self-examination, and ovarian ultrasounds using self-administered questionnaires. The frequency of screening practices between study cohorts were compared using logistic regression. Annual mammography was conducted in 23 and 43% of French and Quebecer women participants <50 years of age, respectively (adjusted odds ratio (aOR)=2.72; 95% confidence interval (CI), 1.08-6.81). In women ≥ 50 years of age, mammography was conducted in 49 and 65% of French and Quebecer participants (aOR=1.77; 95% CI, 0.07-4.51). Overall, 33% of French women and 39% of Quebecer women underwent at least one ovarian ultrasound during the 2-year period following BRCA1/2 test result with no significant difference between cohorts of women < 50 years of age. Among older women, Quebecers reported more frequently than French women that they had undergone ultrasound once (aOR=3.00; 95% CI, 1.02-8.83). The frequency of cancer screening practices for female non-carriers from BRCA1/2 mutation-positive families in both France and Quebec exceeded those recommended for similarly aged women in the general population. Our findings highlight the need for clearcut recommendations on the follow-up of women from BRCA1/2 families who are not themselves carriers of a BRCA1/2 mutation.     

The woman patient after WHI

An epidemic of fear and distrust has infected women (and physicians) after publication of the Women's Health Initiative (WHI). The overinflated negative data emerging from the oestroprogestinic arm of WHI have frightened women and gave rise to the most difficult emotions to cope with. Keywords such as cancer, death and hormones combined together, have potentiated an avoidant attitude towards hormonal therapy (HT) driven more emotionally than rationally. This negative aura has not been dissipated by the positive data from the oestrogen-only arm of WHI. This paper will discuss: women's different emotional reactions to and coping strategies for HT-related fear after WHI; the communication skills physicians should use in focusing on positive messages emerging from WHI; predictors of current HT use; the meaning of the higher use of HT in postmenopausal highly-educated women and women gynaecologists; the importance of increasing healthy life-styles as a taking of responsibility towards aging by every woman; shifting from passivity to active sharing of the decision making process with the caring physician; and the use of an individually tailored HT, when appropriate, as part of an active strategy in the pursuit of a longer health expectancy.     

Prevalence and correlates of hormonal therapy among Israeli women in the post-WHI era

OBJECTIVES: Following the results of recent randomized controlled trials on the risks and benefits of the long-term use of hormonal therapy (HT), practice guidelines regarding HT use have been revised. The aim of the study is to assess the prevalence and the correlates of HT use in Israel in 2003. METHODS: This is a cross-sectional study, conducted on a representative sample of the general population in Israel aged 21 years and over. The study questionnaire is based on the European Health Interview Survey (EUROHIS) project, aimed to develop uniform study tools, to enable international comparisons. The current module of the survey focused on women's health, and telephone interviews were conducted with 1396 women by trained interviewers in the year 2003. RESULTS: Out of a total of 1396 participants, 535 were defined as peri- or postmenopausal (38%). Of them, 9.9% were currently using HT (11.7% and 2.9% among the Jewish and Arab participants, respectively), and their mean age (S.D.) was 57.7 (6.5) years. Mean duration of HT use was 8.0 (5.5) years. Treatment of menopausal symptoms was the most common reason for HT use (69.2%). Significant correlates of HT use were age, being secular and having seen a gynecologist in the previous 12 months. CONCLUSIONS: Current HT use rates reported are lower than those reported 3 years ago for Israeli women. Awareness of both physicians and patients to the WHI results (2002), may have accounted for this trend, at least partially.     

New evidence regarding hormone replacement therapies is urgently required transdermal postmenopausal hormone therapy differs from oral hormone therapy in risks and benefits

Controversies about the safety of different postmenopausal hormone therapies (HTs) started 30 years ago and reached a peak in 2003 after the publication of the results from the Women Health Initiative (WHI) trial and the Million Women Study (MWS) [Writing group for the women's health initiative investigations. Risks and benefits of estrogen plus progestin in healthy postmenopausal women. JAMA 2002;288:321-33; Million women study collaborators. Breast cancer and hormone-replacement therapy in the million women study. Lancet 2003;362:419-27]. The single HT formulation used in the WHI trial for non hysterectomized women-an association of oral conjugated equine estrogens (CEE-0.625 mg/day) and a synthetic progestin, medroxyprogesterone acetate (MPA-2.5 mg/day)-increases the risks of venous thromboembolism, cardiovascular disease, stroke and breast cancer. The MWS, an observational study, showed an increased breast cancer risk in users of estrogens combined with either medroxyprogesterone acetate (MPA), norethisterone, or norgestrel. It is unclear and questionable to what extent these results might be extrapolated to other HRT regimens, that differ in their doses, compositions and administration routes, and that were not assessed in the WHI trial and the MWS. Significant results were achieved with the publication of the WHI estrogen-only arm study [Anderson GL, Limacher M, Assaf AR, et al. Effects of conjugated equine estrogen in postmenopausal women with hysterectomy: the Women's Health Initiative randomized controlled trial. JAMA 2004;291:1701-1712] in which hormone therapy was reserved to women who had carried out hysterectomy. What emerged from this study will allow us to have some important argument to develop.     

Prevalence of HBV, HCV, HIV and HTLV in autologous blood donors in France between 1993 and 2000]

The epidemiological surveillance of autologous blood donors has been carried out in France since 1993. The number of autologous donors increased regularly from 1993 to 1997 but has decreased during the last three years to become less than 50,000 in 2000. The sex-ratio was stable over time (0.85 male for 1 female). The population of autologous donors grew older between 1993 and 2000: the proportion of those aged under 50 years old decreased from 29% in 1993 to 18% in 2000 while the proportion of those over 69 increased from 22 to 34%. Between 1993 and 2000, HbsAg prevalence decreased by a factor of 2.5 and HCV prevalence by a factor of 5. For HIV, a slight decrease was observed and the prevalence of HTLV was stable over time. In 2000, HCV prevalence (0.23%) was two times higher than HBsAg prevalence (0.12%), fifteen times higher than HTLV prevalence in Continental France (0.015%) and one hundred times higher than HIV prevalence (0.002%). The prevalence was similar in men and women for HCV, about two times higher in men than in women for HBsAg and three times higher for HIV. On the contrary, HTLV prevalence was about two times higher in women than in men. HBsAg and HCV prevalence rates were also calculated by age group. The prevalence rates for HBsAg increased up to the 30-39 age group among women and the 40-49 age group among men; then the rates decreased but were higher in men than in women. For HCV, while the prevalence increased continuously with age among women, a peak was reached for men in the 30-39 age group followed by a decrease up to the 50-59 age group and the prevalence was stable afterwards. The very low level of the current risk of transmitting viral infections by homologous transfusion and technical changes in autologous transfusion seem to be the two main factors that contributed to the recent decline in the number of autologous donors. The decrease in HBsAg and anti-HCV prevalence between 1993 and 2000 is multifactorial, but the drop observed for HCV is probably linked to a decrease in HCV prevalence of the general population over the last ten years.     

Hormonal therapy is associated with a lower prevalence of breast arterial calcification on mammography

OBJECTIVE: To bring further understanding to the relationship between hormonal therapy (HT) and breast arterial calcification (BAC). METHODS: Of women arriving for breast cancer screening mammography, 1995 consented to complete a survey and have their mammograms analyzed for the presence of BAC. The survey assessed HT use and major risk factors for CAD. RESULTS: Of the 1919 women with complete data, there were 268 with BAC (14%). When categorized into three age groups, BAC was present in 40.7% of the women > or =65, 10.9% of those 55-64 and 3.0% of those <55. The > or =65 year-old group showed a nearly 50%-point lower prevalence of BAC among HT users compared with women who were not on HT (25.8% versus 74.2%, respectively, p=0.006). With age included as a continuous variable, past use of HT was significantly associated with a lower prevalence of BAC (p<0.03), while the presence of diabetes or a history of stroke were significantly associated with a higher prevalence of BAC (p<0.002). CONCLUSIONS: Well-established cardiovascular risk factors (diabetes, stroke, and age) appear to be associated with a significantly higher incidence of BAC, while HT during the menopausal years appears to be associated with a significantly lower prevalence of BAC.     

Women's views of the climacteric at the time of low menopausal hormone use, Estonia 1998

OBJECTIVES: This study examined women's opinions about the climacteric and hormone therapy (HT) after menopause and compared women's and physicians' opinions in a country of low-HT use. METHODS: In 1998, a postal questionnaire was sent to a random sample of 2000 Estonian 45-64-year-old women; 69% (n=1312) responded. In 1999, a postal questionnaire was sent to a random sample of 500 Estonian gynaecologists and general practitioners; 68% (n=342) responded. RESULTS: Mean age at menopause was 49.8 years (S.D. 4.0), and there was no difference by socioeconomic classes or by age in self-rated health. Ten percent of women reported having used HT, with 3% currently using it. Most women reported some symptoms, with vasomotor symptoms more frequently reported by 50-54 years old; women most often reported tiredness (48%). Half of the women but under a fifth of physicians considered the climacteric a normal phase of life. Women's awareness about HT was low and about half had no opinion on its health effects. Half of the women had visited a gynaecologist, older women less so. Women with contacts with health care were more aware of HT. CONCLUSIONS: Women reported symptoms by age-group as similarly found in high-HT use countries and it verifies that many symptoms experienced were not due to menopause. As in other low-HT use countries, women were unfamiliar with HT and their attitudes were traditional, although physicians' attitudes were more positive. Estonian women seemed to have escaped the period of the preventive use of HT.
