Hormone replacement therapy: knowledge, attitudes, self-reported use - and sales figures in Nordic women

BRCA mutation carriers' perceptions on postmenopausal hormone therapy: An Italian study

Objective

To evaluate the actual perceptions of postmenopausal hormone therapy (HT) in BRCA mutation carriers (BRCAmc) in comparison with women from the general population.

Methods

Questionnaire‐based study of 83 BRCAmc and a control group of 89 women without a genetic mutation. Perceptions were evaluated by specific questions and Likert scales (−5–+5).

Results

Present and past users of HT were more frequent in the control group (p = 0.01), with a longer time of use (p = 0.03). The preferred route of administration of HT was ‘oral’ (54.6%). The most frequently reported adverse effect of HT was venous thrombosis (0.8), while a protective effect on bone health was reported. No noticeable beneficial effects of HT have been recognised for hot flushes (0.2) and vaginal dryness (0.1). The most frequently perceived beneficial and adverse effects of HT were not significantly different between BRCA mutation carriers and controls. The greatest oncological fear was breast cancer (1.0). The protective role of HT on colorectal cancer was not known (0.1). These oncological impacts were mostly overestimated in BRCAmc, however this was not significant. Few BRCAmc would think of taking HT after risk‐reducing surgeries.

Conclusions

Knowledge of the effects of HT on BRCAmc is relatively poor and they are likely to overstate its negative effects and underestimate its health benefits; however, this is not significant in comparison to the general population. More and better information should be given to BRCAmc to allow them to make informed decisions about the use of HT, especially before undergoing risk‐reducing surgeries.

Beliefs, knowledge and the impact of COVID19 on menopause therapies in Spanish women: COMEM-treatment study

OBJECTIVE

To study what women think about menopause treatments and assess their knowledge about them. To analyze adherence to treatment during COVID-19 confinement as a secondary objective.

METHODS

A multi-center cross-sectional observational study was conducted using a survey of 2500 women between January and June 2019. This was administered following a non-probability sampling procedure including women between 35 and 75 years. An extension study was conducted during the coronavirus pandemic, between March and June 2020.

RESULTS

The responses of 2355 surveyed women were analyzed. Of this sample, 42% knew about menopause hormone therapy (MHT). The most frequently identified indication was the treatment of hot flashes (65.6%). The MHT risks most frequently perceived were weight gain (24.2%) and breast cancer (21.7%); the main reason for rejecting MHT was a lack of information (96.1%). Comparative analyses were conducted according to age, menopausal status, type of menopause, place of residence, type of health care and level of education. During the coronavirus confinement period, 85 women using MHT were located, of which 84.7% continued it.

CONCLUSIONS

Women hold certain false beliefs about menopause, and their knowledge of the available treatments is somewhat limited. Adherence to MHT during the COVID-19 confinement in Spain has been high.

Opinions and main sources of information about menopause among middle-aged Brazilian women

OBJECTIVES

The aim of this study was to evaluate women's opinions about menopause and the sources of information they use to deepen their understanding of the topic.

METHODS

Population-based study with 749 Brazilian women aged 45 to 60 years. The answers to the question "What is menopause?" were typed and coded, and categories that emerged from the interviewees' own speech were created. The answers to the question: "Where or from whom did you get information about menopause?" were also analyzed.

RESULTS

The mean age of women was 52.5 (± 4.4) years. Of them, 68% were postmenopausal. According to 67.5% of the interviewees, the concept of menopause encompassed changes in the menstrual cycle and hormones. For 48%, menopause meant physical changes such as "hot flushes and vaginal dryness." For 22.7%, menopause represented psychological changes. The concept of menopause was associated with some change in sexuality for 7.6% of the interviewees. Approximately 18% could not explain what menopause meant. Regarding the sources of information, 44.5% of the women attributed this knowledge to friends and relatives. Doctors or health services were mentioned by 44.3% of women. Television or radio was cited by 22.0%; magazines, newspapers, or books were cited by 14.0%; and the Internet was cited by 6.8% of women. Fifty-two women (6.9%) reported having no source of information about menopause.

CONCLUSIONS

Most of the interviewees relate the term "menopause" to physiological events. There seems to be a suppressed demand for information on the various aspects of the menopausal transition among middle-aged Brazilian women.

Menopause: A complex and controversial journey

Menopause is defined as permanent cessation of menstrual periods, determined retrospectively after a woman has experienced 12 months of amenorrhea without any other obvious cause. Over the years, the discourse surrounding the Climacteric was mainly elicited as a "disease of the castrates", as opposed to the feminist views. There has been a large feminist contribution to both the debate of contraception and menopause in the last few years. Over the years, menopause has been treated in a uniform fashion, as a disease, excluding the different circumstances and lived experiences that patients go through during this sensitive period. Every primary care provider should be familiar with the menopausal process and be able to provide adequate care for these women, respecting patient's autonomy and decision making. A brief historical of menopause and hormone replacement therapy (HRT) will be reviewed in this paper. We will also discuss the different views of the menopausal discourse as well as the benefits and risks, compliance rates and reasons for discontinuation of HRT.

Breast cancer incidence trends in Norway and estimates of overdiagnosis

Objective

Fluctuations in the incidence of breast cancer in Norway in the last three decades are partly explained by the use of hormone replacement therapy and mammography screening, but overdiagnosis has also been suggested as a cause. We assessed the trends in breast cancer incidence and overdiagnosis in Norway.

Methods

We calibrated our microsimulation model to Norwegian Cancer Registration data. The model takes into account the use of mammography (both within and outside the Norwegian Breast Cancer Screening Programme) and of hormone replacement therapy. We obtained a proper fit of breast cancer incidence in recent years, when assuming an increase in the background risk for breast cancer, and estimated overdiagnosis.

Results

We estimated a 2% overdiagnosis rate as a fraction of all cancers diagnosed in women aged 50–100, and a 3% overdiagnosis rate as a fraction of all cancers diagnosed in women aged 50–70 (i.e. screening age). If all of the increased incidence would be the result of the detection of slow growing tumours, these estimates were 7% and 11%, respectively.

Conclusion

Besides mammography and hormone replacement therapy use, additional risk factors contributed to the sudden increase in breast cancer incidence in Norway. Overdiagnosis estimates due to screening were within the range of international plausible estimates.

Menopause: knowledge, attitude and practice among Italian women

OBJECTIVES

Investigating women's knowledge, attitude and practice in relation to menopause and systemic hormone therapy (HT) through a sample survey implemented within the preliminary works for the Consensus Conference "Informing women on hormone replacement therapy" that took place in Turin in May 2008 [Available at www.partecipasalute.it. Last access 7/8/2008].

METHODS

The survey involved representative samples of women 45-60 years from five Italian regions. Twenty trained interviewers distributed the questionnaires reaching participants at their homes. A total of 969 women were selected from electoral rolls. 720 of them completed the interview (74.3% response rate).

RESULTS

Participants reported positive attitudes about menopause; more than 90% believed menopause is a normal phase in women's life and more than 40% stated it is a good experience for a woman. Nevertheless, more than half of the sample did not receive any information about menopause and possible therapies, and those who did, often rated it as poor and contrasting. Moreover, clinicians who prescribed HT reported advantages (94%) much more frequently than disadvantages (22%) and risks (39%) in relation to this treatment. Lack of knowledge was associated with women's low educational level and their no or scarce attitude to attend health services.

CONCLUSIONS

More and qualified information should be provided to support women in making informed choices in relation to menopause and the use of systemic HT. Therefore, actions' should be carried out in order to strengthen the advisory role of clinicians and other sources of information, when taking care of women who may be using or thinking of using HT.

Complexities in the estimation of overdiagnosis in breast cancer screening

There is interest in estimating and attributing temporal changes in incidence of breast cancer in relation to the initiation of screening programmes, in particular to estimation of overdiagnosis of breast cancer as a result of screening. In this paper, we show how screening introduces complexities of analysis and interpretation of incidence data. For example, lead time brings forward time- and age-related increases in incidence. In addition, risk factors such as hormone replacement therapy use have been changing contemporaneously with the introduction of screening. Although we do not indicate exactly how such complexities should be corrected for, we use some simple informal adjustments to show how they may account for a substantial proportion of increased incidence, which might otherwise erroneously have been attributed to overdiagnosis. We illustrate this using an example of analysis of breast cancer incidence data from Sweden.

Early menopause, association with tobacco smoking, coffee consumption and other lifestyle factors: a cross-sectional study

BACKGROUND

Early onset of menopause is a risk factor for several health problems. The objective was primarily to investigate the association between early menopause and current, past active and passive smoking. A second aim was to investigate the association between coffee and alcohol consumption and early menopause.

METHODS

The present population-based cross-sectional study included a sub-sample of 2123 postmenopausal women born in 1940-41 who participated in the Oslo Health Study. Early menopause was defined as menopause occurring at an age of less than 45 years. We applied logistic regression analyses (crude and adjusted odds ratio (OR)) to examine the association between early menopause and selected lifestyle factors.

RESULTS

Current smoking was significantly associated with early menopause (adj. OR, 1.59; 95% CI, 1.11-2.28). Stopping smoking more than 10 years before menopause considerably reduced the risk of early menopause (adj. OR, 0.13; 95% CI, 0.05-0.33). Total exposure to smoking (the product of number of cigarettes per day and time as a smoker) was positively related to early menopause and, at the highest doses, nearly doubled the odds (adj. OR, 1.93; 95% CI, 1.12-3.30). These data suggest a possible dose-response relationship between total exposure to smoking and early menopause, but no dose-response relationship was detected for the other variables examined. We found no significant association of coffee or alcohol consumption with early menopause. Of the lifestyle factors tested, high educational level (adj. OR, 0.50; 95% CI, 0.34-0.72) and high social participation (adj. OR, 0.60, 95% CI, 0.39-0.98) were negatively associated with early menopause.

CONCLUSION

This cross-sectional study shows an association between current smoking and early menopause. The data also suggest that the earlier a woman stops smoking the more protected she is from early menopause. Early menopause was not significantly associated with passive smoking, or alcohol or coffee consumption.

Women's attitudes to hormone replacement therapy in the aftermath of the Women's Health Initiative study

AIM

This paper is a report of a study conducted in 2004 on the determinants of attitudes towards hormone replacement therapy in the aftermath of the report on the findings of the Women's Health Initiative study.

BACKGROUND

The unexpected findings of the Women's Health Initiative study, published in July 2002, showed that the risk of using combined hormones exceeded their benefits. This complicated women's decision-making about hormone use and made it important to study the determinants of their attitudes to hormone therapy, as these are likely to influence their behaviour.

METHODS

A cross-sectional design was conducted with a sample of 561 women drawn from the National Registry of Iceland. A self-administered questionnaire, measuring attitudes towards hormone replacement therapy, attitudes towards menopause, extent and source of menopausal education, symptom experience, health and lifestyle and knowledge about the findings of the Women's Health Initiative, was used. The overall response rate was 56%. Attitudes to hormone replacement therapy were compared using anova, t-tests and correlations.

RESULTS

Participants generally had positive attitudes. Knowledge about the Women's Health Initiative study was not associated with more negative attitudes. However, receiving the information from and discussing it with a doctor were associated with more positive attitudes. Positive attitudes towards hormone therapy were also associated with higher age, time since last menstrual period and current use of hormone replacement therapy. Negative attitudes were associated with use of natural remedies and receiving information from or discussing hormone therapy with family or friends.

CONCLUSION

Research is needed to identify the dynamics of the medical interview, and the nature of input from friends, spouse and other family members. The content of these messages may be different and conflicting, for example, between doctors and family members. The nature of this conflict and conflicts of interests need to be identified in order to inform women's decision-making. In addition, action needs to be taken in order to strengthen the advisory role of nurses.

Trends in middle-aged women's reports of symptoms, use of hormone therapy and attitudes towards it

OBJECTIVES

To investigate changes in middle-aged women's attitudes towards hormone therapy (HT), use of HT and reports of symptoms between 1995 and 2003.

METHODS

All women (n = 2209) in two primary health-care districts received a questionnaire, when aged 45, 50, 55 or 60. The questionnaire consisted of quality of life instruments and items concerning menopause, health, symptoms, attitudes towards HT and use of it.

RESULTS

A total of 1681 women (76%) responded to the questionnaire. Thirty-one percent had used HT, with a mean duration of 4 years. A shift from mainly positive attitudes towards HT and increasing use of HT in the 1990s to largely negative attitudes and decreasing use became evident in 2002-2003. In comparison, current HT users in 2002-2003 were older and had used HT for longer than users in previous years. The number of general symptoms reported tended to increase successively and satisfaction with health to decrease during the period. Women with a history of HT continuously reported a greater number of symptoms than those women who had never used it. Reports of vasomotor symptoms did not change over time.

CONCLUSIONS

The changes that have occurred in beliefs regarding HT have had an impact both on attitudes towards HT and on use of HT among the women we surveyed. The increase in number of general symptoms is discussed in relation to perception of menopause, prescription patterns of HT and changes at the societal level.

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.

Socioeconomic status and use of postmenopausal hormone replacement therapy among Danish women

BACKGROUND

Observational studies on hormone replacement therapy (HRT) have shown cardioprotective effects that have not been replicated in randomized controlled trials, perhaps due to unaccounted confounding by socioeconomic factors. To resolve this discrepancy, we examined the association between socioeconomic status (SES) and HRT use in a large population of Danish postmenopausal women.

METHODS

We conducted a register-based cross-sectional study based on all women aged 40 or more with a permanent address in the North Jutland County, Denmark on 1 January 1999 (n = 122 584). The women were classified according to SES through the Prevention Registry at Statistics Denmark. Through the Pharmaco-epidemiological Prescription Database, we identified all reimbursed HRT prescriptions in North Jutland County for women aged 40 or more in the study population during 1999. We calculated 1-year prevalence proportions of HRT use for all socioeconomic groups. Between-group comparisons were made by log-risk analysis with adjustment for age.

RESULTS

The estimated overall user-prevalence of HRT in 1999 among Danish postmenopausal women was 14.9%[95% confidence interval (CI) 14.7-15.1]. No substantial socioeconomic gradient was found in the study. The adjusted relative prevalence proportions (RPPs) varied between 0.90 and 1.14 among the different groups when using salaried employees, basic level, as the reference group.

CONCLUSIONS

Our findings suggest that recent observational studies on the use of hormone replacement therapy among women in Denmark may not have suffered from strong confounding by socioeconomic status.

Changes in attitudes, knowledge and hormone replacement therapy use: a comparative study in two random samples with 6-year interval

OBJECTIVES

To study changes in: (i) the prevalence of hormone-replacement therapy (HRT) and (ii) women's attitudes and knowledge about the climacteric. Design. Cross-sectional comparison was performed on two populations of women both aged 46-62 years and resident in the same urban Swedish population over a period of 6 years.

MATERIAL AND METHODS

In 1992, a random sample of 5990 women, from five birth cohorts, 46, 50, 54, 58, and 62 years in the city of Göteborg, were assessed using a postal questionnaire technique. In 1998, the same technique was used and a similar questionnaire was sent to another cohort of women (n=5411) of the same ages, resident in the city of Göteborg. The overall response rate was 76%. Information was obtained regarding climacteric symptoms, HRT use, and attitudes and knowledge.

RESULTS

The prevalence of HRT use with medium-potency estrogens had increased from 13% (1992) to 31% (1998). The highest prevalence was reported in women 54 years of age (46%). The most common reasons why women started HRT were: hot flushes and sweats, depression/irritability, sleeping disturbances, and vaginal dryness. Forty-four percent of the women in this study were prepared to consider extended HRT if the treatment was free from withdrawal bleedings (35%, 1992). Eighty percent believed that the risk of osteoporosis decreased during HRT use (61%, 1992) and 68% thought that the risk of breast cancer increased (58%, 1992).

CONCLUSIONS

A marked increase in the use of HRT was reported between 1992 and 1998. Women's attitudes to HRT were more positive in 1998 compared to 1992. Knowledge about HRT among women had increased during the same 6-year period.

Hormone therapy and mortality during a 14-year follow-up of 14 324 Norwegian women

OBJECTIVES

We evaluated mortality from cardiovascular disease (CVD), coronary heart disease (CHD) and all causes in relation to use of any hormone therapy (HT) and HT with oestradiol and norethisterone or levonorgestrel.

DESIGN

Population-based cohort study.

SETTING AND SUBJECTS

Women in three Norwegian counties were invited to a health survey in 1985-88 and 82.8% participated. In all 14 324 post- or perimenopausal women aged 35-62 years, including 702 HT users with a mean age of 48.8 years, were followed for 14 years.

RESULTS

Women using HT had mortality from all causes and CVD comparable with that of nonusers. The relative risk (RRs) for CVD mortality amongst all women were 0.69 (95% CI: 0.35-1.33) for users of HT, and 0.96 (95% CI: 0.43-2.17) for users of HT with norethisterone or levonorgestrel. Amongst women free of self-reported cardiovascular health problems at baseline all-cause, CVD and CHD mortality tended to be lower amongst users of HT whilst HT use was linked with increased mortality amongst women with cardiovascular health problems.

CONCLUSIONS

In this cohort of women around the usual age of menopause all-cause or CVD mortality amongst users of HT, most often oestradiol combined with norethisterone or levonorgestrel, was not markedly different from that of nonusers. Early CHD events amongst HT users prior to the baseline survey, together with selective inclusion of healthy subjects, may in part explain protective effects of HT on CHD reported from previous observational studies.

Factors associated with intention to use hormone replacement therapy among Thai middle-aged women

OBJECTIVES

To examine the differences among those who express their intentions to use hormone replacement therapy (intenders), those who express their intentions not to use hormone replacement therapy (non-intenders), and those who are undecided, and to examine the factors associated with hormone replacement therapy (HRT) intention among Thai middle-aged women.

METHODS

A total of 420 women aged 40-59 years, recruited from one hospital in Bangkok were asked to complete a self-administered questionnaire.

RESULTS

Compared to intenders and non-intenders, the undecided were significantly less knowledgeable about menopause and HRT, and perceived the highest level of decisional uncertainty. Being inadequately informed was the most important factor that distinguished the undecided from intenders and non-intenders. When looking at intenders and non-intenders, no significant differences in perceived information inadequacy, level of knowledge, and perceived risks of HRT were found. However, it was found that intenders perceived higher benefit over risk of HRT (OR = 1.05, 95% CI = 1.02, 1.07), held more negative beliefs towards menopause (OR = 1.61, 95% CI = 1.03, 2.53), and were approximately two times more likely to have ever used oral contraceptives (OR = 1.99, 95% CI = 1.13, 3.47) than non-intenders.

CONCLUSION

The findings reveal the importance of being informed about menopause and HRT in making decision about HRT use. Changes in knowledge, and beliefs are promising avenues to study to see how these impacts HRT use.

Associations between attitudes toward hormone therapy and current use of it in middle-aged women

OBJECTIVES

To investigate the association between attitudes toward hormone therapy (HT) and use of it and explanatory factors for the association found.

METHODS

All women in two primary healthcare districts aged 45, 50, 55 or 60 in 2000 or 2001 (n=771) received a questionnaire consisting of quality-of-life instruments and items concerning menopause, health, healthcare, symptoms, sociodemographic factors and attitudes toward HT.

RESULTS

A total of 564 women (74%) responded to the questionnaire. In the women with a positive or a neutral attitude, rather than a negative one, the age- and menopause-adjusted odds ratios for current HT use were 18.55 (95% CI 8.55, 40.11) and 2.61 (1.15, 5.93), respectively. Health-related factors, factors concerning one's own person and psychosocial factors were the groups of factors found to contribute to explaining the association between attitudes and current HT use. Together, the three groups of factors explained 42 and 98%, respectively, of a positive and a neutral attitude's association with current use of HT. Individual factors of importance in these factor groups were a feeling of being appreciated outside the home, satisfaction with one's work, marital status, own climacteric period, visits to a physician and past use of hormonal contraceptives. In contrast, level of education and the occurrence of cold sweats/hot flushes was not found to contribute to the explanation.

CONCLUSIONS

Factors concerned with women's everyday life, contentment with oneself and use of healthcare services were of importance in explaining the associations between attitudes toward HT and current use of it. Consideration at these factors in counselling women about HT is recommended.

Prevalence and determinants of hormone replacement therapy in German women 1984-1995

OBJECTIVES

To describe trends in prevalence and determinants of hormone replacement therapy (HRT) in German women.

METHODS

Three representative samples of women in Augsburg, Germany were examined in the MONICA surveys in 1984/85 (45-64 years; N=1013), 1989/90 and 1994/95 (both 45-74 years; N=1496 and 1475) by interview and anthropometry, and all drugs taken during the previous week were documented. The prevalence of HRT use was calculated by survey, age group and HRT type, and various characteristics were evaluated as determinants for any systemic HRT use by logistic regression.

RESULTS

The prevalence of HRT use in women aged 45-64 years in 1984/85, 1989/90 and 1994/95 was 3, 9% (age 45-74, 6%) and 23% (17%), respectively. In 1994/1995, positive determinants of HRT use were daily consumption of salad and vegetables, having quit smoking (vs. current smoking), regular exercise, ever having taken oral contraceptives, body mass index <25 kg/m(2) and age, and negative determinants were not drinking alcohol and education for <9 years (all P-value <0.10 in multivariate model). After multiple adjustment, HRT users were five times more likely to have participated in cancer screening and to have visited a gynaecologist >or=5 times during the previous year, and were less likely not to have seen a general practitioner or gynaecologist (all P-values <0.001).

CONCLUSION

HRT use increased substantially in Germany between 1984 and 1995. Women with characteristics associated with lower morbidity and mortality were more likely to use HRT, which agrees with the healthy-user phenomenon described in other countries.
