Menopause Symptom Score (MRS)の包括的な教育ガイドを準備中です。ステップバイステップの解説、数式、実例、専門家のヒントをお届けしますので、もうしばらくお待ちください。
The Menopause Rating Scale (MRS) is a validated, self-administered health-related quality of life questionnaire developed to assess the severity of menopausal symptoms and their impact on wellbeing. Originally published by Heinemann et al. in 1994 and revised for widespread use in 2003, the MRS comprises 11 items across three subscales: Somatic (vasomotor and physical symptoms — hot flushes, sweating, cardiac discomfort, sleep disturbance, joint and muscle complaints); Psychological (mood and cognitive symptoms — depressive mood, irritability, anxiety, mental exhaustion); and Urogenital (genitourinary symptoms — sexual problems, bladder problems, vaginal dryness). Each item is rated on a 5-point Likert scale from 0 (no symptoms) to 4 (very severe symptoms), giving a maximum total score of 44. A total score of 9 or above is generally considered significant, indicating symptoms that warrant clinical assessment and consideration of treatment. The MRS is useful for determining STRAW+10 (Stages of Reproductive Aging Workshop) staging in clinical practice — the internationally accepted framework for classifying reproductive ageing from the final menstrual period (FMP). Menopause is defined as the permanent cessation of menstrual periods due to loss of ovarian follicular activity, confirmed retrospectively after 12 consecutive months of amenorrhoea with no other pathological or physiological cause. Hormone Replacement Therapy (HRT), now more commonly called Menopausal Hormone Therapy (MHT), remains the most effective treatment for vasomotor symptoms and has proven benefits for bone health, cardiovascular risk (when started within 10 years of menopause), and quality of life.
MRS Total Score = Sum of all 11 items (each 0-4); Range 0-44. Somatic subscale (items 1-4): max 16; Psychological subscale (items 5-8): max 16; Urogenital subscale (items 9-11): max 12. Score >=9 = significant symptoms
- 1The woman self-completes the 11-item questionnaire, rating each symptom from 0 (none) to 4 (very severe) based on her experience over the past 4 weeks.
- 2Score the Somatic subscale: sum items 1–4 (hot flushes/sweating, cardiac symptoms, sleep disturbance, joint/muscle complaints); maximum 16.
- 3Score the Psychological subscale: sum items 5–8 (depressive mood, irritability, anxiety, mental and physical exhaustion); maximum 16.
- 4Score the Urogenital subscale: sum items 9–11 (sexual problems, bladder problems, vaginal dryness); maximum 12.
- 5Calculate the total MRS score by summing all three subscales (0–44).
- 6Interpret: 0–8 = mild or no significant symptoms; 9–16 = moderate symptoms; 17–44 = severe symptoms requiring active management.
- 7Reassess MRS at follow-up visits (typically 3 months after initiating HRT and 6-monthly thereafter) to evaluate treatment response and adjust therapy as needed.
First-line HRT: transdermal oestradiol + micronised progesterone (Utrogestan) if uterus intact
Total score of 15 falls in the moderate range. Hot flushes significantly impact quality of life. HRT is the most effective treatment and this score supports initiating a discussion about risks and benefits.
Prioritise somatic and psychological domains; consider combined transdermal HRT + SSRIs if depression prominent
A score of 37 indicates severely impactful symptoms across all three domains. Quality of life is substantially compromised. The benefits of HRT in this case strongly outweigh risks for a healthy 54-year-old woman aged under 60 and within 10 years of menopause.
Vaginal oestrogen addition (Vagifem/Ovestin) may further address urogenital symptoms
A 61% reduction in MRS total score confirms effective HRT response. Residual urogenital symptoms may not fully respond to systemic HRT alone; local vaginal oestrogen is safe to add and highly effective for vaginal dryness and sexual discomfort.
POI HRT dose may need to be higher than standard postmenopausal HRT to achieve symptom control
In POI (menopause before age 40), HRT is recommended not only for symptom control but as essential health protection against premature osteoporosis and cardiovascular disease. MRS provides a useful baseline and outcome measure.
Professionals in health and medical use Menopause Symptoms as part of their standard analytical workflow to verify calculations, reduce arithmetic errors, and produce consistent results that can be documented, audited, and shared with colleagues, clients, or regulatory bodies for compliance purposes.
University professors and instructors incorporate Menopause Symptoms into course materials, homework assignments, and exam preparation resources, allowing students to check manual calculations, build intuition about input-output relationships, and focus on conceptual understanding rather than arithmetic.
Consultants and advisors use Menopause Symptoms to quickly model different scenarios during client meetings, enabling real-time exploration of what-if questions that would otherwise require returning to the office for detailed spreadsheet-based analysis and reporting.
Individual users rely on Menopause Symptoms for personal planning decisions — comparing options, verifying quotes received from service providers, checking third-party calculations, and building confidence that the numbers behind an important decision have been computed correctly and consistently.

| Total Score | Severity | Clinical Action |
|---|---|---|
| 0–8 | Mild / No significant symptoms | Lifestyle advice; reassurance; no HRT required unless specifically requested |
| 9–16 | Moderate | HRT discussion; risk-benefit counselling; initiate if appropriate |
| 17–28 | Severe | HRT strongly indicated; address individual risk factors |
| 29–44 | Very severe | Urgent HRT initiation; consider multidisciplinary input (menopause clinic) |
What is the difference between perimenopause and menopause?
Perimenopause refers to the transitional period leading up to the final menstrual period (FMP), during which cycles become irregular and menopausal symptoms begin. It typically lasts 4–6 years but can extend longer. Menopause is the point of the FMP itself, confirmed retrospectively after 12 months of amenorrhoea. Postmenopause refers to the years after the FMP. Many women experience the most severe symptoms during perimenopause, not after menopause.
Is HRT safe?
Modern HRT (particularly transdermal oestradiol with micronised progesterone) has a substantially better safety profile than older oral combined HRT. Transdermal oestradiol does not increase VTE (blood clot) risk. Micronised progesterone has a lower breast cancer risk signal than synthetic progestogens. For healthy women under 60 or within 10 years of menopause, the benefits of HRT for symptom control, bone protection, and cardiovascular health typically outweigh risks. Individual risk assessment is essential.
What is the STRAW+10 staging system?
The Stages of Reproductive Aging Workshop (STRAW) system divides the female reproductive lifespan into stages: reproductive (early, peak, late), menopausal transition (early: irregular cycles; late: amenorrhoea ≥60 days), and postmenopause (early: first 6 years; late: remaining years). STRAW+10 (updated 2012) added criteria including hormonal (FSH, AMH) and ultrasound (AFC) parameters to characterise each stage more precisely and improve clinical applicability.
What non-hormonal options are available for menopausal symptoms?
For vasomotor symptoms: SSRIs/SNRIs (paroxetine, venlafaxine, desvenlafaxine), clonidine, gabapentin, and fezolinetant (a neurokinin 3 receptor antagonist, NICE approved 2024) are evidence-based non-hormonal options. For urogenital symptoms: local vaginal oestrogen is highly effective and has minimal systemic absorption. Cognitive behavioural therapy (CBT) has good evidence for hot flushes and mood symptoms. Lifestyle measures (reduced alcohol, weight management, cooling strategies) provide modest benefit.
Does HRT increase breast cancer risk?
Breast cancer risk with HRT depends on the type and duration of treatment. Oestrogen-only HRT (in women without a uterus) does not appear to increase and may slightly reduce breast cancer risk in some studies. Combined oestrogen-progestogen HRT is associated with a small increased risk, particularly after 5 years of use. Micronised progesterone (Utrogestan) has a lower risk signal than synthetic progestogens such as medroxyprogesterone acetate. The absolute risk increase is small — approximately 5 extra cases per 1,000 women over 5 years of use.
What is premature ovarian insufficiency (POI)?
POI is defined as the cessation of ovarian function before the age of 40, occurring in approximately 1% of women. It is diagnosed by elevated FSH (>25 IU/L on two measurements 4–6 weeks apart) combined with amenorrhoea or oligomenorrhoea. POI requires HRT (not contraceptive pills) until the natural age of menopause (approximately 51 years) to prevent premature bone loss and cardiovascular disease. Unlike natural menopause, POI is associated with 5–10% chance of spontaneous ovulation and conception.
Can menopausal symptoms affect work and relationships?
Yes significantly. A 2021 UK Menopause Society survey found that approximately 1 in 10 women leave work due to menopausal symptoms and nearly 1 in 3 report that symptoms negatively impact their work performance. Cognitive symptoms ('brain fog'), fatigue, low mood, and sleep disturbance have the greatest impact on occupational function. Effective treatment substantially improves quality of life, work productivity, and relationship satisfaction.
How long should HRT be taken?
There is no mandated maximum duration for HRT. Duration should be based on individual assessment of symptoms, risks, and benefits reviewed annually. Many women choose to take HRT for 5–10 years or longer for symptom control, bone protection, and quality of life. The NICE menopause guideline (NG23) states that HRT may be continued for as long as the benefits outweigh the risks for the individual woman.
プロのヒント
Use the three MRS subscales separately as well as the total score. A woman with a low total score but a high urogenital subscale may be an ideal candidate for topical vaginal oestrogen alone without systemic HRT. A high psychological subscale score warrants assessment for clinical depression or anxiety disorder, which may coexist with but is distinct from menopausal mood symptoms.
ご存知でしたか？
The word 'menopause' derives from the Greek 'men' (month) and 'pausis' (cessation), reflecting its original definition as the cessation of monthly menstrual periods. The average age of menopause in the UK and US is 51 years, with a normal range of 45–55 years. Women who smoke experience menopause approximately 2 years earlier than non-smokers.
