Menopause symptoms and chronic pain in a national sample of midlife women veterans

Accumulation of β-aminoisobutyric acid mediates hyperalgesia in ovariectomized mice through Mas-related G protein-coupled receptor D signaling

Hyperalgesia is typified by reduced pain thresholds and heightened responses to painful stimuli, with a notable prevalence in menopausal women, but the underlying mechanisms are far from understood. β-Aminoisobutyric acid (BAIBA), a product of valine and thymine catabolism, has been reported to be a novel ligand of the Mas-related G protein coupled receptor D (MrgprD), which mediates pain and hyperalgesia. Here, we established a hyperalgesia model in 8-week-old female mice through ovariectomy (OVX). A significant increase in BAIBA plasma level was observed and was associated with decline of mechanical withdrawal threshold, thermal and cold withdrawal latency in mice after 6 weeks of OVX surgery. Increased expression of MrgprD in dorsal root ganglion (DRG) was shown in OVX mice compared to Sham mice. Interestingly, chronic loading with BAIBA not only exacerbated hyperalgesia in OVX mice, but also induced hyperalgesia in gonadally intact female mice. BAIBA supplementation also upregulated the MrgprD expression in DRG of both OVX and intact female mice, and enhanced the excitability of DRG neurons in vitro. Knockout of MrgprD markedly suppressed the effects of BAIBA on hyperalgesia and excitability of DRG neurons. Collectively, our data suggest the involvement of BAIBA in the development of hyperalgesia via MrgprD-dependent pathway, and illuminate the mechanisms underlying hyperalgesia in menopausal women.

From maca to marijuana: cultural influences on joint pain symptoms and management in urban perimenopausal and early postmenopausal Latinas

OBJECTIVE

The purpose of this qualitative study was to explore the symptom experience and coping strategies for managing joint pain during the menopause transition in urban Latina women.

METHODS

We conducted focus groups with 13 English-speaking peri and early postmenopausal Latinas living in Upper Manhattan in New York City in 2014. Eligible participants were self-identified Latinas aged 45 to 60 years with new onset or worsening joint pain and spontaneous amenorrhea, recruited through flyers and snowball sampling. Focus group interviews conducted in English were audiotaped, transcribed, and analyzed by a bilingual research team, using NVivo software (QSR International) to organize and code themes.

RESULTS

On average, participants were aged 51.7 ± 4.8 years and overweight (body mass index of 29.3 ± 6.7 kg/m2); 10 (76.9%) were Puerto Rican, and the last menstrual period was 1 month to 5 years ago. The following four themes emerged: 1) menopause and joint pain are an alarming package; 2) pain disrupts life and livelihood; 3) medical management is unsatisfactory and raises worries about addiction; and 4) home remedies for coping with pain-from maca to marijuana. Despite access to a world-class medical facility in their neighborhood, women seeking pain relief preferred to self-manage joint pain with exercise, over-the-counter products, and other culturally valued home remedies. Many suffered through it.

CONCLUSIONS

For midlife Latinas, joint pain symptoms may emerge or worsen unexpectedly as part of the menopause transition and carry distressing consequences for daily activities and quality of life. There is a need to develop more culturally specific approaches for menopause-related pain management in this underserved population.

Musculoskeletal pain among Chinese women during the menopausal transition: findings from a longitudinal cohort study

ABSTRACT

The profiles of muscle and joint pain throughout the menopausal transition and the factors associated with these symptoms have not been determined. A total of 609 participants from a longitudinal cohort study conducted in an urban Chinese community were enrolled in this study. We assessed the prevalence of musculoskeletal symptoms at different menopausal stages and explored the factors associated with these symptoms. The prevalence and severity of muscle and joint pain increase as menopausal stages progress, and late menopausal transition may be a crucial timepoint that triggers the onset of musculoskeletal pain. The results of the multivariate analysis revealed that poor health status (OR = 2.245, 95% CI = 1.714-2.94, P < 0.001), body mass index (BMI) (OR = 1.046, 95% CI = 1.01-1.084, P = 0.011), the presence of anxiety (OR = 1.601, 95% CI = 1.211-2.117, P < 0.001), and depression (OR = 1.368, 95% CI = 1.143-1.639, P < 0.001) were independently associated with muscle and joint pain. In addition, the severity of musculoskeletal pain was related to poor health status (OR = 2.738, 95% CI = 1.91-3.924, P < 0.001) and depression (OR = 1.371, 95% CI = 1.095-1.718, P = 0.006). Musculoskeletal symptoms are frequent somatic symptoms experienced by Chinese middle-aged women. Women with poor health status, high BMI, anxiety, and depression were at heightened risk of experiencing musculoskeletal pain. The severity of pain increased over time.

Estrogen receptor GPR30 in the anterior cingulate cortex mediates exacerbated neuropathic pain in ovariectomized mice

Menopausal women experience neuropathic pain 63% more frequently than men do, which may attribute to the estrogen withdrawal. However, the underlying mechanisms remain unclear. Here, the role of estrogen receptors (ERs) in ovariectomized (OVX) female mice following chronic constriction injury (CCI) was investigated. With 17β-estradiol (E2) supplemented, aggravated mechanical allodynia in OVX mice could be significantly alleviated, particularly after intra-anterior cingulate cortex (ACC) E2 delivery. Pharmacological interventions further demonstrated that the agonist of G-protein-coupled estrogen receptor 30 (GPR30), rather than ERα or ERβ in the ACC, exhibited the similar analgesic effect as E2, whereas antagonist of GPR30 exacerbated allodynia. Furthermore, OVX surgery reduced GPR30 expression in the ACC, which could be restored with estrogen supplementation. Selective downregulation of GPR30 in the ACC of naïve female mice induces mechanical allodynia, whereas GPR30 overexpression in the ACC remarkedly alleviated OVX-exacerbated allodynia. Collectively, estrogen withdrawal could downregulate the ACC GPR30 expression, resulting in exacerbated neuropathic pain. Our findings highlight the importance of GPR30 in the ACC in aggravated neuropathic pain during menopause, and offer a potential therapeutic candidate for neuropathic pain management in menopausal women.

Effectiveness of proprioceptive neuromuscular facilitation therapy and strength training among post-menopausal women with thumb carpometacarpal osteoarthritis. A randomized trial

BACKGROUND

Thumb carpometacarpal osteoarthritis (CMC OA) greatly affects post-menopausal women. It is characterized by pain and functional deficits that limit the performance of activities of daily life and affect quality of life.

PURPOSE

Analyze the effects of 4/weeks strength training, with and without proprioceptive neuromuscular facilitation (PNF) on the disability among post-menopausal women with thumb CMC OA. Secondly, analyze the effects on pain, mobility, and strength.

STUDY DESIGN

Superiority randomized clinical trial.

METHODS

42 women were randomly allocated to strength training program (SEG, n = 21) and to a strength training plus PNF therapy program (PNFG, n = 21). The Disability (disabilities of the arm, shoulder and hand questionnaire), pain (visual analogue scale), mobility (Kapandji Test), and hand strength were evaluated pre, post intervention (at 4 weeks) and follow-up (at 8 weeks).

RESULTS

Disability was significantly reduced in both groups after intervention, but reduction was statistically superior in PNFG (between-group mean difference [MD] = -16.69 points; CI = -21.56:-11.82; P<.001; d = 2.14). Similar results were observed for secondary outcomes: pain (MD = -2.03; CI = -2.83:-1.22; P<.001; d = 1.58), mobility (MD = 0.96; CI = 0.52:1.38; P<.001; d = 1.40) and strength (grip: MD = 3.47kg; CI = 1.25:5.69; P = .003; d = 0.97, palmar: MD = 0.97kg; CI = 0.14:1.80; P = .024; d = 0.72, tip: MD = 1.12kg; CI = 0.41:1.83; P = .003; d = 0.99 and key pinch: MD = 0.85kg; CI = 0.001:1.70; P = .049; d = 0.62). These improvements were maintained at follow-up.

CONCLUSIONS

The combination of PNF exercises and strength training is more effective for reducing disability pain and improve mobility and strength in post-menopausal women with CMC OA than a programme based solely on strength.

Sex and Sleep Disruption as Contributing Factors in Alzheimer's Disease

Alzheimer's disease (AD) affects more women than men, with women throughout the menopausal transition potentially being the most under researched and at-risk group. Sleep disruptions, which are an established risk factor for AD, increase in prevalence with normal aging and are exacerbated in women during menopause. Sex differences showing more disrupted sleep patterns and increased AD pathology in women and female animal models have been established in literature, with much emphasis placed on loss of circulating gonadal hormones with age. Interestingly, increases in gonadotropins such as follicle stimulating hormone are emerging to be a major contributor to AD pathogenesis and may also play a role in sleep disruption, perhaps in combination with other lesser studied hormones. Several sleep influencing regions of the brain appear to be affected early in AD progression and some may exhibit sexual dimorphisms that may contribute to increased sleep disruptions in women with age. Additionally, some of the most common sleep disorders, as well as multiple health conditions that impair sleep quality, are more prevalent and more severe in women. These conditions are often comorbid with AD and have bi-directional relationships that contribute synergistically to cognitive decline and neuropathology. The association during aging of increased sleep disruption and sleep disorders, dramatic hormonal changes during and after menopause, and increased AD pathology may be interacting and contributing factors that lead to the increased number of women living with AD.

Perceptions of pain in aging females undergoing spinal cord stimulation

Aim: Effects of age and sex on chronic pain outcomes following spinal cord stimulation (SCS) have not yet been assessed. Methods: We retrospectively reviewed 1 year outcomes from a database of patients receiving thoracic SCS. Subjects were divided into four cohorts: pre-menopausal and post-menopausal females, and aged-matched males. Improvement using the numerical rating scale, Oswestry Disability Index (ODI), Beck's Depression Inventory (BDI), McGill Pain Questionnaire and Pain Catastrophizing Scale (PCS) was assessed. Results: Older females were notably different from males and females under 60 as they had greater improvements in ODI, BDI and PCS. Further, females ≥60 had greater improvement in PCS compared with males ≥60. Conclusion: Our findings suggest greater improvement with 1 year SCS treatment in post-menopausal females, compared with age-matched males.

The importance of female reproductive history on self-reported sleep quality, mood, and urogenital symptoms in midlife

OBJECTIVE

This study investigated the importance of reproductive history on somatic and psychological symptoms in midlife women.

METHODS

A total of 503 women from 39 to 65 years of age were recruited from different localities in Slovakia. These were interviewed about their reproductive and menstrual history, sociodemographic background, and lifestyle and health status after submitting pretested questionnaires. All variables were measured by self-reporting, and multivariable logistic and ordinal regression analyses tested the associations.

RESULTS

Women who experienced miscarriage had a greater likelihood of waking early and then sleeping poorly, and they also felt unattractive in midlife. Moreover, women with two or more miscarriages were four times more likely to experience this sleep symptom than those without miscarriage (odds ratio [OR], 4.2; 95% confidence interval [CI], 1.70-10.38; P = 0.002). In addition, women with one or two children suffered significantly less often with severe depressed mood and lack of enjoyment than women with three and more children (lack of enjoyment: with one child, the OR was 0.39 [95% CI, 0.16-0.96; P = 0.041]; with two children, the OR was 0.47 [95% CI, 0.23-0.97; P = 0.040]; depressed mood: with one child, the OR was 0.32 [95% CI, 0.12-0.84; P = 0.021]). Finally, the premenopausal and perimenopausal women were less likely to experience severe vaginal dryness than those in postmenopause.

CONCLUSIONS

This cross-sectional pilot study suggests that women's reproductive history, as determined by parity and miscarriage, may be relevant to their midlife health and well-being. Future research is warranted.

Understanding chronic pain in the ubiquitous community: the role of open data

The combined use of social media, open data, and Artificial Intelligence has the potential to support practitioners and empower patients/citizens living with persistent pain, both as local and online communities. Given the wide availability of digital technology today, both practitioners and interested individuals can be connected with virtual communities and can support each other from the comfort of their homes. Digital means may represent new avenues for exploring the complexity of the pain experience. Online interactions of patients, data on effective treatments, and data collected by wearable devices may represent an incredible source of psychological, sociological, and physiological pain-related information. Digital means might provide several solutions that enhance inclusiveness and motivate patients to share personal experiences, limiting the sense of isolation in both rural and metropolitan areas. Building on the consensus of the usefulness of social media in enhancing the understanding of persistent pain and related subjective experiences via online communities and networks, we provide relevant scenarios where the effectiveness and efficiency of healthcare delivery might be improved by the adoption of the digital technologies mentioned above and repeated subsequently. The aim of this perspective paper is to explore the potential of open data, social media, and Artificial Intelligence in improving the prevention and management of persistent pain by adopting innovative non-biomedical approaches.

Low back pain and osteoarthritis pain: a perspective of estrogen

Low back pain (LBP) is the world's leading cause of disability and is increasing in prevalence more rapidly than any other pain condition. Intervertebral disc (IVD) degeneration and facet joint osteoarthritis (FJOA) are two common causes of LBP, and both occur more frequently in elderly women than in other populations. Moreover, osteoarthritis (OA) and OA pain, regardless of the joint, are experienced by up to twice as many women as men, and this difference is amplified during menopause. Changes in estrogen may be an important contributor to these pain states. Receptors for estrogen have been found within IVD tissue and nearby joints, highlighting the potential roles of estrogen within and surrounding the IVDs and joints. In addition, estrogen supplementation has been shown to be effective at ameliorating IVD degeneration and OA progression, indicating its potential use as a therapeutic agent for people with LBP and OA pain. This review comprehensively examines the relationship between estrogen and these pain conditions by summarizing recent preclinical and clinical findings. The potential molecular mechanisms by which estrogen may relieve LBP associated with IVD degeneration and FJOA and OA pain are discussed.

Association of earlier age at menopause with risk of incident dementia, brain structural indices and the potential mediators: a prospective community-based cohort study

Background

To date, there is no homogeneous evidence of whether earlier age at menopause is associated with incident dementia. In addition, the underlying mechanism and driven mediators are largely unknown. We aimed to fill these knowledge gaps.

Methods

This community-based cohort study included 154,549 postmenopausal women without dementia at enrolment (between 2006 and 2010) from the UK Biobank who were followed up until June 2021. We followed up until June 2021. Age at menopause was entered as a categorical variable (<40, 40-49, and ≥50 years) with ≥50 years taken as a reference. The primary outcome was all-cause dementia in a time-to-event analysis and the secondary outcomes included Alzheimer's disease, vascular dementia, and other types of dementia. In addition, we investigated the association between magnetic resonance (MR) brain structure indices with earlier menopause, and explored the potential underlying driven mediators on the relationship between earlier menopause and dementia.

Findings

2266 (1.47%) dementia cases were observed over a median follow-up period of 12.3 years. After adjusting for confounders, women with earlier menopause showed a higher risk of all-cause dementia compared with those ≥50 years (adjusted-HRs [95% CIs]: 1.21 [1.09-1.34] and 1.71 [1.38-2.11] in the 40-49 years and <40 years groups, respectively; P for trend <0.001). No significant interactions between earlier menopause and polygenic risk score, cardiometabolic factors, type of menopause, or hormone-replacement therapy strata were found. Earlier menopause was negatively associated with brain MR global and regional grey matter indices, and positively associated with white matter hyperintensity. The relationship between earlier menopause and dementia was partially mediated by menopause-related comorbidities including sleep disturbance, mental health disorder, frailty, chronic pain, and metabolic syndrome, with the proportion (95% CI) of mediation effect being 3.35% (2.18-5.40), 1.38% (1.05-3.20), 5.23% (3.12-7.83), 3.64% (2.88-5.62) and 3.01% (2.29-4.40), respectively. Multiple mediator analysis showed a combined effect being 13.21% (11.11-18.20).

Interpretation

Earlier age at menopause was associated with risk of incident dementia and deteriorating brain health. Further studies are warranted to clarify the underlying mechanisms by which earlier age at menopause is linked to an increased risk of dementia, and to determine public health strategies to attenuate this association.

Prevalence of hypertension and correlation with mental health in women with burning mouth syndrome: A case-control study

Background

The relationship between hypertension (HTN) and chronic pain is still a matter of debate, and its prevalence in patients with burning mouth syndrome (BMS) has never been evaluated. This study aimed to assess the prevalence of HTN in women with BMS and to evaluate its relationship with potential predictors such as risk factors for cardiovascular diseases, pain, and mental health status analyzing differences with healthy women.

Methods

In total, 250 women with BMS (WBMS) were prospectively recruited and compared with an equal number of healthy women (HW) matched for age. Education, body mass index, smoke and alcohol consumption, intensity and quality of pain, and psychological profile were further investigated to identify the potential predictors of HTN. Specifically, pain assessment [the Numeric Rating Scale (NRS) and Short-Form McGill Pain Questionnaire (SF-MPQ)] and psychological assessment [Hamilton Rating Scale for Depression and Anxiety (HAM-D and HAM-A), Pittsburgh Sleep Quality Index (PSQI), and Epworth Sleepiness Scale (ESS)] was carried out for the participants.

Results

HTN was found in 128 (51.2%) WBMS and 76 (30.4%) HW (p < 0.001^**). The scores of the NRS, SF-MPQ, HAM-D, HAM-A, and PSQI were statistically significantly higher in the WBMS than in the HW (p < 0.001^**). A strongly linear correlation between HTN and employment status, systemic diseases, and education level (p < 0.001^**) was found in WBMS, while a strong correlation between HTN and employment status, hypercholesterolemia, systemic diseases, and drug consumption was found in HW (p < 0.001^**). No statistically significant correlation was found between HTN and pain, anxiety, depression, and sleep disturbances.

Conclusion

These results suggest that WBMS showed a higher prevalence of HTN compared with controls. Unemployed WBMS with lower education and other systemic comorbidities are at an increased risk of developing HTN. HTN is associated with alteration in the vascular structure and function of the brain, and these processes accelerate brain aging, which contributes to a reduction in intracortical connectivity, thus affecting the modulatory system of control of pain in patients with BMS, independently of their mental health assessment. Predictors that may underlie this association remain unclear, taking into account the differences found in HW, and should be further elucidated.

Racial/ethnic disparities in the diagnosis and management of menopause symptoms among midlife women veterans

OBJECTIVE

Racial/ethnic disparities in menopause symptoms and hormone therapy management remain understudied among women served by the Veteran's Health Administration, despite the unique racial/ethnic diversity of this population. Thus, we determined racial/ethnic disparities in medical record-documented menopause symptoms and prescribed menopausal hormone therapy among women veterans.

METHODS

We conducted cross-sectional analyses of national Veteran's Health Administration electronic health record data from 2014 to 2015. We used logistic regression models to compare medical-record documented menopause symptoms and treatment (eg, vaginal estrogen or systemic hormone therapy) by self-identified race/ethnicity, adjusting for age, body mass index, and depression. Models examining hormone treatment were adjusted for menopause symptoms.

RESULTS

Among 200,901 women veterans (mean age 54.3, SD 5.4 y; 58% non-Hispanic/Latinx White, 33% non-Hispanic/Latinx Black, 4% Hispanic/Latinx, and 4% other), 5% had documented menopause symptoms, 5% were prescribed vaginal estrogen, and 5% were prescribed systemic hormone therapy. In fully adjusted multivariable models, non-Hispanic/Latinx Black women veterans had lower odds of documented menopause symptoms relative to non-Hispanic/Latinx White women (OR 0.82, 95% CI: 0.78-0.86). Moreover, non-Hispanic/Latinx Black women (OR 0.74, 95% CI: 0.70-0.77), as well as Hispanic/Latinx women (OR 0.68, 95% CI: 0.61-0.77), had lower likelihood of systemic hormone therapy prescription. Hispanic/Latinx women had higher odds of vaginal estrogen prescription (OR 1.12 95% CI: 1.02-1.24) than non-Hispanic/Latinx White women. Non-Hispanic/Latinx Black women had lower likelihood of estrogen use (OR 0.78 95% CI: 0.74-0.81) than non-Hispanic/Latinx White women.

CONCLUSION

Despite evidence suggesting higher menopause symptom burden among Black women in community samples, documented menopause symptoms and hormone therapy were less common among Black, compared with White, women veterans. Additionally, Hispanic/Latinx women veterans had lower odds of prescribed systemic menopause therapy and yet higher odds of prescribed vaginal estrogen, despite no difference in documented symptoms. These findings may signal important disparities in symptom reporting, documentation, and/or treatment for minority women veterans.

Pain in midlife women: a growing problem in need of further research

More than 10% of American adults experience some level of daily pain, and nearly 40 million (17.6%) experience episodes of severe pain annually. Women are particularly impacted by both episodic and chronic pain with higher prevalence and a greater level of pain-related disability compared to men. Midlife is a critical period for women during which the frequency of pain complaints begins to increase. Although pain is known to be influenced and controlled by sex hormones, it has not been widely recognized as a symptom of the menopausal transition outside of the menopause research community. The recent thematic series in this journal has specifically highlighted pain related conditions including rheumatoid arthritis, migraine and abdominal pain for which the significance among midlife women is not typically recognized. The studies presented in this thematic series present a small fraction of relevant, understudied questions regarding pain and its impact on women in midlife. Addressing the gaps in knowledge will require longitudinal studies that consider the emergence of pain symptomatology in relation to midlife trajectories of other symptoms and health determinants, as well as further study of new and emerging therapies.

The Causal Role of Magnesium Deficiency in the Neuroinflammation, Pain Hypersensitivity and Memory/Emotional Deficits in Ovariectomized and Aged Female Mice

Purpose

Postmenopausal women often suffer from chronic pain, memory decline and mood depression. The mechanisms underlying the neuronal disorders are not fully understood, and effective treatment is still lacking.

Methods

Oral administration of magnesium-L-threonate was tested to treat the neuronal disorders in ovariectomized and aged female mice. The pain hypersensitivity, memory function and depression-like behaviors were measured with a set of behavioral tests. Western blots, immunochemistry and in situ hybridization were used to assess molecular changes.

Results

Chronic oral administration of magnesium-L-threonate substantially prevented or reversed the chronic pain and memory/emotional deficits in both ovariectomized and aged female mice. We found that phospho-p65, an active form of nuclear factor-kappaB, tumor necrosis factor-alpha and interleukin-1 beta were significantly upregulated in the neurons of dorsal root ganglion, spinal dorsal horn and hippocampus in ovariectomized and aged mice. The microglia and astrocytes were activated in spinal dorsal horn and hippocampus. Calcitonin gene–related peptide, a marker for peptidergic C-fibers, was upregulated in dorsal horn, which is associated with potentiation of C-fiber-mediated synaptic transmission in the model mice. In parallel with neuroinflammation and synaptic potentiation, free Mg²⁺ levels in plasma, cerebrospinal fluid and in dorsal root ganglion neurons were significantly reduced. Oral magnesium-L-threonate normalized the neuroinflammation, synaptic potentiation and Mg²⁺ deficiency, but did not affect the estrogen decline in ovariectomized and aged mice. Furthermore, in cultured dorsal root ganglion neurons, estrogen at physiological concentration elevated intracellular Mg²⁺, and downregulated phospho-p65, tumor necrosis factor-alpha and interleukin-1 beta exclusively in the presence of extracellular Mg²⁺.

Conclusion

Estrogen decline in menopause may cause neuroinflammation by reducing intracellular Mg²⁺ in neurons, leading to chronic pain, memory/emotional deficits. Supplement Mg²⁺ by oral magnesium-L-threonate may be a novel approach for treating menopause-related neuronal disorders.

Prevalence of pain in women living with HIV aged 45-60: associated factors and impact on patient-reported outcomes

As the population of women with HIV ages, an increasing proportion are experiencing the menopause, with potential associated pain. Among 844 participants in the Positive Transitions Through the Menopause (PRIME) study (72.3% black African; median age 49 (interquartile-range 47-53) years; 20.9%, 44.0% and 35.1% pre-, peri- and post-menopausal), 376 (44.6%) and 73 (8.7%) reported moderate or extreme pain. Women had been diagnosed with HIV for 14 (9-18) years, 97.7% were receiving antiretroviral therapy and 88.4% had a suppressed viral load. In adjusted ordinal logistic regression, peri-menopausal status (adjusted odds ratio (1.80) [95% confidence interval 1.22-2.67]), current smoking (1.85 [1.11-3.09]), number of comorbid conditions (1.95 [1.64-2.33] /condition) and longer duration of HIV (1.12 [1.00-1.24]/5 years) were independently associated with increased reported pain, whereas being in full-time work (0.61 [0.45-0.83]) and having enough money for basic needs (0.47 [0.34-0.64]) were associated with decreased pain reporting. Increasing pain was independently related to insomnia symptoms (moderate: 2.76 [1.96-3.90]; extreme: 8.09 [4.03-16.24]) and severe depressive symptoms (PHQ4 ≥ 6; moderate: 3.96 [2.50-6.28]; extreme: 9.13 [4.45-18.72]). Whilst our analyses cannot determine the direction of any associations, our findings point to the importance of eliciting a history of pain and addressing symptoms in order to improve wellbeing.

Individual and additive-effect relationships of sleep problems and severe menopausal symptoms among women in menopausal transition

OBJECTIVE

Sleep problems and menopausal symptoms are both common complaints among midlife women. However, the associations of the quality and quantity of sleep problems with the severity of menopausal symptoms have not been well studied. Thus, this study aims to examine the relationships between individual sleep problems and the additive number of sleep problems with severe menopausal symptoms among women during the menopausal transition.

METHODS

Using the convenience sampling, a total of 848 middle-aged women in China were investigated from December 2017 to August 2018. All participants completed a questionnaire on sleep problems, Menopause Rating Scale, and the general information questionnaire. Based on the cutoff of the Menopause Rating Scale, participants were divided into the nonsevere menopausal symptom group and severe menopausal symptoms group. Propensity score matching was used to balance covariates between the two groups. Stepwise binary logistic regression and restricted cubic spline were applied to analyze the associations of individual and additive sleep problems with severe menopausal symptoms.

RESULTS

After propensity score matching, no significant difference was observed between the nonsevere menopausal symptoms group and severe menopausal symptoms group (Ps > 0.05). Logistic regression analysis showed that five sleep problems ("feeling too hot," "having pain," "restless legs syndrome," "taking medicine to help sleep," and "having trouble staying awake") were closely associated with severe menopausal symptoms. The restricted cubic spline curve showed an upward trend in odds ratios between the number of these five sleep problems and severe menopausal symptoms, and women were more than twice as likely to suffer severe menopausal symptoms when they experienced more than three of these individual sleep problems.

CONCLUSION

Both the individual and additive number of sleep problems exerted significant effects on severe menopausal symptoms. It might be useful for healthcare providers to set guidelines to support a healthy menopausal transition for midlife women.
