Hormonal substitution during menopause: what are we treating?

Association of Hormone Therapy With Depression During Menopause in a Cohort of Danish Women

IMPORTANCE

During menopause, the levels of estrogen and progesterone decrease and 60% to 70% of women experience menopausal symptoms, including mood disturbances. The latter might be prevented by hormone therapy (HT), yet some studies have suggested that use of HT might be associated with increased risk of depression.

OBJECTIVE

To examine whether use of HT during menopause was associated with a subsequent diagnosis of depression.

DESIGN, SETTING, AND PARTICIPANTS

This nationwide register-based cohort and self-controlled case series study included all women in Denmark aged 45 years between January 1, 1995, through December 31, 2017 (n = 825 238), without prior oophorectomy, breast cancer, or cancer in reproductive organs. Follow-up was completed on December 31, 2018. The statistical analysis was performed from September 1, 2021, through May 31, 2022.

EXPOSURES

Redeemed prescriptions of different types of HT identified by the Anatomical Therapeutic Chemical classification system codes (G03C [estrogen] and G03F [estrogen combined with progestin]) in the Danish National Prescription Registry between 1995 and 2017. Type of administration was divided into systemic (oral or transdermal) and local (intravaginal or intrauterine).

MAIN OUTCOMES AND MEASURES

A hospital diagnosis of depression (International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, codes F32-F33 and International Classification of Diseases, Eighth Revision, codes 296.09, 296.29, 298.0, and 300.49) between 1995 through 2018. Associations were examined in cohort and self-controlled case series analysis using Cox proportional hazards and fixed-effects Poisson regression models.

RESULTS

During follow-up from 45 years of age to a mean of 56.0 (range, 45.1-67.7) years, 189 821 women (23.0%) initiated systemically or locally administered HT and 13 069 (1.6%) were diagnosed with depression. Systemically administered HT was mainly initiated before 50 years of age and was associated with a higher risk of a subsequent depression diagnosis (hazard ratio [HR] for 48-50 years of age, 1.50 [95% CI, 1.24-1.81]). The risk was especially elevated the year after initiation of both treatment with estrogen alone (HR, 2.03 [95% CI, 1.21-3.41]) and estrogen combined with progestin (HR, 2.01 [95% CI,1.26-3.21]). Locally administered HT was initiated across all ages and was not associated with depression risk (HR, 1.15 [95% CI, 0.70-1.87]). It was, however, associated with a lower risk of depression when initiated after 54 years of age (HR for 54-60 years of age, 0.80 [95% CI, 0.70-0.91]). In self-controlled analysis, which efficiently accounts for time-invariant confounding, users of systemically administered HT had higher rates of depression in the years after initiation compared with the years before treatment (incidence rate ratio for 0-1 year after initiation, 1.66 [95% CI, 1.30-2.14]).

CONCLUSIONS AND RELEVANCE

These findings suggest that systemically administered HT before and during menopause is associated with higher risk of depression, especially in the years immediately after initiation, whereas locally administered HT is associated with lower risk of depression for women 54 years or older.

Additive effect of depressed mood and vasomotor symptoms on postmenopausal insomnia

OBJECTIVE

The aim of this study was to investigate the role of vasomotor and mood symptoms on insomnia in postmenopausal women.

METHODS

One hundred sixty-three postmenopausal women, not receiving hormone therapy, attending a menopause clinic at the University of Athens, Greece, were included in this cross-sectional study. Climacteric symptoms were assessed by Greene's scale, whereas psychological morbidity was measured by Zung Self-Assessment Depression Scale, Symptom Checklist-90-R, and Athens Insomnia Scale.

RESULTS

Vasomotor symptoms were significantly associated with insomnia (P = 0.001). When depressive symptomatology was added to the logistic regression analysis, the predictive ability of the model was significantly improved as defined by the increase in the log likelihood (P < 0.001) and the increase in the area under the receiver operating characteristic curve.

CONCLUSIONS

Insomnia in postmenopausal women attending a menopause clinic is related both to the effects of vasomotor symptoms and depressive symptomatology. Mood symptoms seem to affect sleep independently of vasomotor symptoms, suggesting that depression should be carefully assessed and treated in postmenopausal women with insomnia.

Age-specific symptom prevalence in women 35-64 years old: a population-based study

Background

Symptom prevalence is generally believed to increase with age. The aim of this study was to evaluate the age specific prevalence of 30 general symptoms among Swedish middle-aged women.

Methods

A cross-sectional postal questionnaire study in seven Swedish counties in a random sample of 4,200 women 35–64 years old, with 2,991 responders. Thirty general symptoms included in the Complaint Score subscale of the Gothenburg Quality of Life Instrument were used.

Results

Four groups of age specific prevalence patterns were identified after adjustment for the influence of educational level, perceived health and mood, body mass index, smoking habits, use of hormone replacement therapy, and use of other symptom relieving therapy. Only five symptoms (insomnia, leg pain, joint pain, eye problems and impaired hearing) increased significantly with age. Eleven symptoms (general fatigue, headache, irritability, melancholy, backache, exhaustion, feels cold, cries easily, abdominal pain, dizziness, and nausea) decreased significantly with age. Two symptoms (sweating and impaired concentration) had a biphasic course with a significant increase followed by a significant decrease. The remaining twelve symptoms (difficulty in relaxing, restlessness, overweight, coughing, breathlessness, diarrhoea, chest pain, constipation, nervousness, poor appetite, weight loss, and difficulty in urinating) had stable prevalence with age.

Conclusion

Symptoms did not necessarily increase with age instead symptoms related to stress-tension-depression decreased.

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.

The menopausal transition was associated in a prospective study with decreased health functioning in women who report menopausal symptoms

OBJECTIVE

To examine change in health functioning as women progress through the menopausal transition.

STUDY DESIGN AND SETTING

Prospective study of 2,489 women followed through four phases of the Whitehall II study. Health functioning was assessed with the eight subscales of the SF-36.

RESULTS

Compared with peri- and postmenopausal women who did not experience menopausal symptoms, women who reported vasomotor symptoms or menopausal depression experienced large and significant declines on most scales of the SF-36. Women who reported the greatest symptom severity experienced the largest declines in functioning. For example, decline in physical functioning for perimenopausal women experiencing severe vasomotor symptoms was 3.3 (standard error SE=1.1) greater than those who experienced no vasomotor symptoms. Decline in role limitation-emotional for perimenopausal women experiencing severe menopause-associated depression was 18.4 (SE=2.3), compared with those who did not experience these symptoms. Vasomotor symptom reporting was predicted by low socioeconomic position, high body mass index, and limiting long-term illness at baseline. Menopause-associated depression was additionally predicted by smoking and depression.

CONCLUSION

The menopausal transition is associated with decreased health functioning in women who report menopausal symptoms. Menopausal symptoms are strongly related to all aspects of health functioning assessed by the SF-36. Socioeconomic and behavioral risk factors for menopausal symptoms and associated declines in health functioning have been identified.

Citalopram and fluoxetine in the treatment of postmenopausal symptoms: a prospective, randomized, 9-month, placebo-controlled, double-blind study

OBJECTIVE

Nonhormonal treatment of postmenopausal symptoms is a subject of great interest today. The results of studies on selective serotonin reuptake inhibitors (SSRIs) are promising, but long-term results do not exist. The objective of this study was to evaluate the efficacy of citalopram and fluoxetine in the treatment of physical and psychological menopausal symptoms and their effects on psychosocial and sexual well being in symptomatic postmenopausal women.

DESIGN

One hundred fifty healthy women suffering from menopausal symptoms were recruited to this placebo-controlled double-blind study with a follow-up period of 9 months. They were randomized into three groups receiving placebo, fluoxetine, or citalopram. The initial dose was 10 mg of both fluoxetine and citalopram, and it was increased to 20 mg at 1 month and to 30 mg at the 6-month visit. The main outcome measures were hot flushes and Kupperman index. The RAND-36 Quality of Life questionnaire, Beck's Depression Scale, and the McCoy Female Sexuality Questionnaire were used at every control visit.

RESULTS

There were no statistically significant differences between the groups in respect to number of hot flushes, Kupperman index, or Beck's Depression Scale, although there was a tendency in all these parameters in favor of SSRIs versus placebo. Insomnia improved significantly in the citalopram group versus placebo. Discontinuation rates at nine months were 40% in the placebo group, 34% in the fluoxetine group and 34% in the citalopram group.

CONCLUSIONS

Compared with placebo, citalopram and fluoxetine have little effect on hot flushes and cannot therefore be recommended for the treatment of menopausal symptoms, if vasomotor symptoms are the main complaint. Whether the improvement of insomnia by means of citalopram affects the quality of sleep needs further investigation.

An evaluation of the benefits of taking hormone replacement therapy with other prescription drugs

OBJECTIVES

Clinical trials of hormone replacement therapy (HRT) exclude women who have other health problems. The aim of our community survey was to investigate the impact of HRT on women with a variety of other health problems.

METHOD

Questionnaire sample of 935 women aged 45-58 years. The questionnaire assessed menopausal quality of life (QOL); self reported health status, prescription drug use and history of hormone supplement use.

RESULTS

Thirty five percent of the total sample had taken a variety of prescription drugs in the last 2 months. Prescription drug use was significantly higher in current and former users of HRT/ERT than in non-HRT/ERT users. Current and former HRT users who also took prescription drugs had a significantly lower mean length of HRT/ERT use when compared to women who took HRT/ERT with no prescription drugs. Peri and postmenopausal women currently taking HRT/ERT reported significantly higher MQOL than both former and non-HRT users, which suggest that the benefits of taking hormone supplements during the menopausal transition for some women. There was a significant interaction between hormone use, level of prescription drug use and QOL. Among women who have high levels of prescription drug use, those who take hormone supplements report significantly fewer deficits in QOL when compared to non or former users of HRT/ERT. Additionally, women taking selective serotonin re-uptake inhibitors (SSRI) plus HRT report significantly higher levels of QOL compared to women taking SSRI alone.

CONCLUSIONS

The advantages of taking HRT among who take prescription drugs could be attributed to the mood enhancing effects of estrogens. HRT should be considered for some peri and postmenopausal women who are taking SSRIs or who are taking at least three different types of prescription drugs.

Menopausal transition and increased depressive symptomatology: a community based prospective study

OBJECTIVE

Prevalence of depression is suggested to be substantially higher in women around menopause. Declining estrogen levels might be an explanation. This study attempts to determine whether depressive symptomatology in healthy women is independently related to menopausal transition.

METHOD

All caucasian women born between 1941 and 1947, living in the city of Eindhoven the Netherlands were invited to take part in a screening program (n=8098) of whom 78% participated (n=6648). About 92% returned the questionnaires of which 81% (n=4975) was fully completed. Women using estrogens and/or having undergone hysterectomy and/or ovariectomy were excluded (43.6%). Of the remaining 2820 women, after 3.5 years, 2748 returned another postal questionnaire, of which 76% was fully completed (n=2103). Depressive symptomatology was assessed using the Edinburgh Depression Scale (EDS). Independent relationship between an intra-individual change in EDS score during the follow-up period and menopausal transition was analysed by multiple logistic regression (enter as well as stepwise method).

RESULTS

Beside the classical determinants of depression (unemployment OR 3.1, CI 1.6-5.8, inability to work OR 1.7, CI 1.0-2.8, financial problems OR 2.9, CI 1.1-7.3 death of a partner OR 2.6, CI 1.1-6.1, death of a child OR 5.9, CI 1.1-32.1 and a previous episode of depression OR 2.0, CI 1.5-2.7) transition from pre to perimenopause and peri to postmenopause was significantly related to a high increase (>5.4) of the EDS score (OR 1.8, CI 1.1-3.3 and OR 1.8, CI 1.5-2.7, respectively).

CONCLUSION

The transition from pre to perimenopause as well as from peri to postmenopause seems to be independently related to a high increase of depressive symptomatology. This suggests that the decrease of ovarian estrogen production is a risk factor for depressive symptomatology.

The impact of testosterone imbalance on depression and women's health

Women suffer more often from depression than males, indicating that hormones might be involved in the etiology of this disease. Low as well as high testosterone (T) levels are related to depression and well-being in women, T plasma levels correlate to depression in a parabolic curve: at about 0.4-0.6 ng/ml plasma free T a minimum of depression is detected. Lower levels are related to depression, osteoporosis, declining libido, dyspareunia and an increase in total body fat mass. Androgen levels in women decrease continuously to about 50% before menopause compared to a 20-year-old women. Androgen levels even decline 70% within 24 h when women undergo surgical removal of the ovaries. Conventional oral contraception or HRT cause a decline in androgens because of higher levels of SHBG. Hyperandrogenic states exist, like hirsutism, acne and polycystic ovary syndrome. Social research suggests high androgen levels cause aggressive behavior in men and women and as a consequence may cause depression. Higher androgen values are more pronounced at young ages and before and after delivery of a baby and might be responsible for the "baby blues". It was found that depression in pubertal girls correlated best with an increase in T levels in contrast to the common belief that "environmental factors" during the time of growing up might be responsible for emotional "up and downs". T replacement therapy might be useful in perimenopausal women suffering from hip obesity, also named gynoid obesity. Abdominal obesity in men and women is linked to type 2 diabetes and coronary heart diseases. Testosterone replacement therapy in hypoandrogenic postmenopausal women might not only protect against obesity but also reduce the risk of developing these diseases. Antiandrogenic progestins might be useful for women suffering from hyperandrogenic state in peri- and postmenopause. Individual dosing schemes balancing side effects and beneficial effects are absolutely necessary. Substantial interindividual variability in T plasma values exists, making it difficult to utilize them for diagnostic purposes. Therefore a "four-level-hormone classification scheme" was developed identifying when estradiol (E) and T levels are out of balance. (1) Low E-low T levels are correlated with osteoporosis, depression, and obesity; (2) high E-low T with obesity, decreased libido; (3) high T-low E levels with aggression, depression, increased libido, and substance abuse; (4) high E-high T with type II diabetes risk, breast cancer and cardiovascular risk. Testosterone delivery systems are needed where beneficial and negative effects can be balanced. Any woman diagnosed for osteoporosis should be questioned for symptoms of depression.

Climacteric complaints in the community

BACKGROUND

At the onset of the climacteric, healthy middle-aged women present with a variety of complaints, especially in general practice. In these first years of entering the menopause, vaginal blood loss alters from irregular periods to complete amenorrhoea. According to these different menstrual patterns, we can distinguish a pre-, peri- and postmenopausal phase. It could be useful to know whether specific climacteric complaints are related to these different phases.

OBJECTIVE

The aim of this study was to investigate the relationship between climacteric complaints and the menstrual pattern during the menopausal transition in a population-based cross-sectional survey of healthy middle-aged women.

METHODS

All women aged 47-54 years, living in the city of Eindhoven, were invited to participate in the Eindhoven Osteoporosis Study (EPOS); 6648 (78%) agreed to participate. All women completed a questionnaire concerning climacteric complaints. Climacteric status was defined by menstrual history. Odds ratios (ORs) were obtained for the relationship between climacteric status and climacteric complaints. Multiple logistic regression analysis was carried out, with climacteric status as the dependent variable.

RESULTS

Of the 27 items in the questionnaire concerning climacteric complaints, seven were significantly different between all three climacteric phases (P: < 0.1). After multiple logistic regression analysis, comparing peri- and premenopause, only flushing (OR 5.9) was significantly different. Between post- and perimenopause, seven symptoms appeared to be different: three urogenital complaints [vaginal dryness (OR 1.6), vaginal discharge (OR 0.4) and pain during intercourse (OR 1.9)], three vasomotor symptoms [daytime sweating (OR 1.4), night-time sweating (OR 0.7) and flushing (OR 1.9)] and, finally, insomnia (OR 1.3). When comparing post- and premenopause, flushing (OR 13.4), insomnia (OR 2.1) and depressed mood (OR 0.6) were significantly different, in addition to three urogenital symptoms: vaginal dryness (OR 2.6), vaginal discharge (OR 0.3) and pain during intercourse (OR 2.1).

CONCLUSION

The major findings of the study are that flushing is strongly associated with the transition from pre- to perimenopause, while urogenital complaints, daytime sweating and insomnia are more prominent in the transition from peri- to postmenopause.
