Does Endometriosis Disturb Mental Health and Quality of Life? A Systematic Review and Meta-Analysis

Cross-disciplinary working between gynaecologists and mental healthcare professionals: a mixed-methods systematic review protocol

INTRODUCTION

Reproductive hormone transitions (menstrual cycle, post partum and menopause) can trigger mental disorders in a subset of women. Gynaecological diseases, such as endometriosis and polycystic ovary syndrome, can also elevate the risk of mental illness. The link between psychiatrists and obstetricians is already well established in the peripartum period; however, the link between gynaecology and psychiatry is less so. This mixed-methods systematic review aims to synthesise the existing evidence for integrated mental healthcare for gynaecological illnesses or reproductive hormone transitions outside the perinatal period.

METHODS AND ANALYSIS

A systematic search of the MEDLINE, Embase, Scopus, PsycInfo, CINAHL and Web of Science databases will be conducted. All study types will be considered, both quantitative and qualitative. Opinion and expert consensus statements, as well as government and professional body documents, will also be included, but separately analysed and reported. Studies examining the unmet clinical needs and experiences of women experiencing mental disorders related to reproductive hormone transitions (menarche, menstrual, menopause, but not pregnancy or breast feeding) or gynaecological illness will be included. Studies related to the experience or training of professionals caring for them will be included, specifically on the concept of integrated or interdisciplinary work with colleagues outside their specialty. Abstracts of the identified papers will be screened independently by two reviewers. Full texts will be assessed by two reviewers, and data will be extracted using predetermined data extraction tools. Quantitative studies will be synthesised in narrative format. A thematic synthesis of qualitative studies will be conducted and an integrated narrative synthesis will be described.

ETHICS AND DISSEMINATION

Ethical approval is not required for this systematic review, as no primary data will be collected. The results will be disseminated via a peer-reviewed publication in a relevant scientific journal.

Connecting the Dots on Female Digital Health Education: A Systematic Review

Identified barriers to care for common, chronic conditions that impact millions of females suggest that patient education is critical to improving the care experience, expediting a diagnosis, and elevating outcomes. This article aims to understand the efficacy of digital patient education interventions on patient outcomes, specifically those addressing common causes of chronic abnormal uterine bleeding, premenstrual dysphoric disorder, and endometriosis. We queried MEDLINE, PubMed, Cochrane Library, and Google Scholar for articles published in English between January 1, 2014, and May 1, 2024, on digital patient education and urogenital diseases. The search identified 260 articles, 247 of which were retrieved for title and abstract review, 27 of which were retrieved for full-text review, and 25 of which were excluded. Two studies were included in this review. Both studies were individual-/community-level interventions involving digitally delivered patient education. Participants had received a diagnosis and were engaged in accessing care when enrolled, and each study was conducted at a single site. Both interventions produced positive results. Despite the potential of digital health education to improve patient outcomes, limited research in this field underscores the need for further studies to validate interventions and address gaps in knowledge.

Understanding the impact of endometriosis on women's life: an integrative review of systematic reviews

BACKGROUND

Endometriosis is a challenging chronic condition with a significant impact on women's well-being. This systematic review of systematic reviews aims to assess the evidence investigating the intricate interplay between endometriosis and quality of life (QoL).

METHODS

A systematic review was performed for English-language studies up to January 2022 to identify systematic reviews with and without meta-analysis analyzing quantitative or qualitative data The following databases were searched: Scopus, PubMed, Embase, Web of Science and Cochrane Central Register of Controlled Trials. Participants/population were women with endometriosis, and the outcomes included were all reported outcomes evaluating the impact of endometriosis on women's QoL (PROSPERO 2021 CRD42021289347).

RESULTS

15 systematic reviews were identified. 8 included meta-analysis: 4 explored the prevalence of mental health problems, and 1 analyzed, respectively, the overall impact of endometriosis, headache migraine, and sexual function. 7 articles reported on the mental consequences, and three sexual functioning. One was a qualitative review. The impact of the relationships with the healthcare system was analyzed in 3 reviews. Pain is a hallmark of endometriosis. Infertility and sexual problems are also frequent. Depression, anxiety, and stress represent significant contributors to lessening women's QoL. Women have frustrating relationships with the healthcare system: the complex and long diagnostic process, lack of treatment effectiveness, and persistence of symptoms contribute to emotional challenges. Negative cognitive patterns developed by women with emotional distress, such as catastrophizing and fear-avoidance behaviors, amplify the experience of pain.

CONCLUSION

The limitations of this review are the high degree of heterogeneity of papers that include many factors, including comorbidities, and use of medical care that may impact QoL, and that most of them were cross-sectional. Endometriosis is a chronic disease that significantly impacts all domains of women's lifes. Pain, infertility, and stress linked with depression, and anxiety significantly influence QoL. Women are dissatisfied with the care they receive.

Influence of App-Based Self-Management on the Quality of Life of Women With Endometriosis

INTRODUCTION

Endometriosis can significantly impair the quality of life of those affected. Multimodal self-help measures are recommended but are often difficult to access. Smartphone apps have been shown to improve the quality of life for other conditions with chronic pain. The aim of this study was to examine the impact of the Endo-App (Endo Health GmbH, Chemnitz, Germany) on both disease-related quality of life and symptoms of endometriosis affecting it.

METHODS

In the present randomized, controlled pilot study, the impact of utilizing the Endo-App on the quality of life among a sample of 122 women affected by endometriosis is assessed. To measure the changes over a 12-week period, the study incorporates the validated Endometriosis Health Profile (EHP-5 and EHP-30) questionnaire from Oxford University, among other assessment tools.

RESULTS

The use of the Endo-App leads to significant changes in the following areas after 12 weeks compared to the control group: pain disability, pain self-efficacy, fatigue, depressive symptoms, and Endometriosis Health Profile scores. The EHP-5 score from T0 to T12 is reduced by -16.76 (p-value of the Mann-Whitney U test (pU) = 0.008), and the EHP-30 score by -15.48 (pU = 0.004). The results remain significant in sensitivity analyses. The effect size of Cohen's d was in the medium range.

CONCLUSION

In summary, the Endo-App improves both physical and psychological symptoms and the patient's self-efficacy. The Endo-App contributes to improving endometriosis care in Germany and enables women suffering from endometriosis to significantly increase their quality of life.

Endometriosis, Pain, and Related Psychological Disorders: Unveiling the Interplay among the Microbiome, Inflammation, and Oxidative Stress as a Common Thread

Endometriosis (EM), a chronic condition in endometrial tissue outside the uterus, affects around 10% of reproductive-age women, significantly affecting fertility. Its prevalence remains elusive due to the surgical confirmation needed for diagnosis. Manifesting with a range of symptoms, including dysmenorrhea, dyschezia, dysuria, dyspareunia, fatigue, and gastrointestinal discomfort, EM significantly impairs quality of life due to severe chronic pelvic pain (CPP). Psychological manifestations, notably depression and anxiety, frequently accompany the physical symptoms, with CPP serving as a key mediator. Pain stems from endometrial lesions, involving oxidative stress, neuroinflammation, angiogenesis, and sensitization processes. Microbial dysbiosis appears to be crucial in the inflammatory mechanisms underlying EM and associated CPP, as well as psychological symptoms. In this scenario, dietary interventions and nutritional supplements could help manage EM symptoms by targeting inflammation, oxidative stress, and the microbiome. Our manuscript starts by delving into the complex relationship between EM pain and psychological comorbidities. It subsequently addresses the emerging roles of the microbiome, inflammation, and oxidative stress as common links among these abovementioned conditions. Furthermore, the review explores how dietary and nutritional interventions may influence the composition and function of the microbiome, reduce inflammation and oxidative stress, alleviate pain, and potentially affect EM-associated psychological disorders.

Endometriosis and mental health: a population-based cohort study

BACKGROUND

Endometriosis is a chronic gynecologic disorder that leads to considerable pain and a reduced quality of life. Although its physiological manifestations have been explored, its impact on mental health is less well defined. Existing studies of endometriosis and mental health were conducted within diverse healthcare landscapes with varying access to care and with a primary focus on surgically diagnosed endometriosis. A single-payer healthcare system offers a unique environment to investigate this association with fewer barriers to access care while considering the mode of endometriosis diagnosis.

OBJECTIVE

Our objective was to assess the association between endometriosis and the risk for mental health conditions and to evaluate differences between patients diagnosed medically and those diagnosed surgically.

STUDY DESIGN

A matched, population-based retrospective cohort study was conducted in Ontario and included patients aged 18 to 50 years with a first-time endometriosis diagnosis between January 1, 2010, and July 1, 2020. Endometriosis exposure was determined through either medical or surgical diagnostic criteria. A medical diagnosis was defined by the use of the corresponding International Classification of Disease diagnostic codes from outpatient and in-hospital visits, whereas a surgical diagnosis was identified through inpatient or same-day surgeries. Individuals with endometriosis were matched 1:2 on age, sex, and geography to unexposed individuals without a history of endometriosis. The primary outcome was the first occurrence of any mental health condition after an endometriosis diagnosis. Individuals with a mental health diagnosis in the 2 years before study entry were excluded. Cox regression models were used to generate hazard ratios with adjustment for hysterectomy, salpingo-oophorectomy, infertility, pregnancy history, qualifying surgery for study inclusion, immigration status, history of asthma, abnormal uterine bleeding, diabetes, fibroids, hypertension, irritable bowel disorder, migraines, and nulliparity.

RESULTS

A total of 107,832 individuals were included, 35,944 with a diagnosis of endometriosis (29.5% medically diagnosed, 60.5% surgically diagnosed, and 10.0% medically diagnosed with surgical confirmation) and 71,888 unexposed individuals. Over the study period, the incidence rate was 105.3 mental health events per 1000 person-years in the endometriosis group and 66.5 mental health events per 1000 person-year among unexposed individuals. Relative to the unexposed individuals, the adjusted hazard ratio for a mental health diagnosis was 1.28 (95% confidence interval, 1.24-1.33) among patients with medically diagnosed endometriosis, 1.33 (95% confidence interval, 1.16-1.52) among surgically diagnosed patients, and 1.36 (95% confidence interval, 1.2-1.6) among those diagnosed medically with subsequent surgical confirmation. The risk for receiving a mental health diagnosis was highest in the first year after an endometriosis diagnosis and declined in subsequent years. The cumulative incidence of a severe mental health condition requiring hospital visits was 7.0% among patients with endometriosis and 4.6% among unexposed individuals (hazard ratio, 1.56; 95% confidence interval, 1.53-1.59).

CONCLUSION

Endometriosis, regardless of mode of diagnosis, is associated with a marginally increased risk for mental health conditions. The elevated risk, particularly evident in the years immediately following the diagnosis, underscores the need for proactive mental health screening among those newly diagnosed with endometriosis. Future research should investigate the potential benefits of mental health interventions for people with endometriosis with the aim of enhancing their overall quality of life.

Assessment of quality of life, psychological aspects, and sexual function of women with endometriosis according to pain and infertility: a cross sectional study

PURPOSE

To evaluate the quality of life, sexual function, anxiety, and depression of women with endometriosis according to pain symptoms and infertility.

METHODS

This cross-sectional multicenter study included 229 women with endometriosis followed up at a tertiary hospital in Campinas, a tertiary hospital in São Paulo, and a reproductive medicine clinic in Campinas from 2018 to 2021. The women were divided into four groups according to the presence of pain symptoms and infertility. The Endometriosis Health Profile Questionnaire, Female Sexual Function Index, Beck Depression Inventory, and Beck Anxiety Index were applied to assess quality of life, sexual function, depression, and anxiety of women with endometriosis.

RESULTS

The women were grouped as follows: group 1 (45 women without infertility and without pain), group 2 (73 women without infertility and with pain), group 3 (49 women with infertility and without pain), and group 4 (62 women with infertility and pain). Of the women with infertility, the majority had primary infertility. Most women had deep endometriosis (p = 0.608). Women with pain had higher anxiety and depression scores and worse quality of life than women without pain (p < 0.001). Regarding sexual function, all the groups were at risk for sexual dysfunction (p = 0.671). The group of women with pain and infertility have worse anxiety scores (25.31 ± 15.96) and depression (18.81 ± 11.16) than the other groups.

CONCLUSION

Pain symptoms worsen anxiety, depression, and quality of life of women with endometriosis and when associated with infertility, greater impairment of psychological aspects may occur.

Mindfulness intervention effect on endometriosis-related pain dimensions and its mediator role on stress and vitality: a path analysis approach

Endometriosis-related pain is supposedly mainly responsible for generating psychological stress and deteriorating the quality of life. However, the interaction between these factors has not been investigated, considering its multidimensional nature and through the path of effects of psychosocial approaches. The present study aims to investigate the effect of a brief mindfulness-based intervention (bMBI) on pain dimensions and its mediator role on psychological stress and QoL-Vitality improvement. A secondary analysis of a pilot randomized controlled trial using a series of parallel and serial mediators was carried out. The results showed that bMBI improves the sensory (B = -6.09 [-9.81, -2.52], β = -0.42) and affective (B = -3.40 [-5.02, -1.80], β = -0.47) pain. The bMBI effect on psychological stress reduction was mediated by these changes in sensory (B = -2.81 [-6.06, -0.41], β = -0.21) and affective (B = -1.97 [-5.07, -0.17], β = -0.15) pain. Serial sensory pain and psychological stress reduction (B = 2.27 [0.11, 5.81], β = -0.09) mediated the bMBI effect on quality of life vitality. Meditation training promotes additional improvement in affective and sensory pain characteristics through which psychological stress is reduced. The sensory pain dimension must be positively impacted in combination with psychological stress for the bMBI improves women's vitality. Adding a psychosocial intervention like meditation training to the standard treatment plan may be required for some women to achieve the needed changes to restore well-being.

Correlation between pain and depressive symptoms in patients with confirmed endometriosis during COVID-19 pandemic

BACKGROUND

Endometriosis is a chronic, estrogen-dependent, inflammatory condition which affects women of reproductive age physically and psychologically in their everyday life. The most common symptom is chronic lower abdominal pain. Apart from physical pain, endometriosis often also leads to an unfulfilled desire to give birth. In general, these two main aspects alone lead to emotional stress for patients and often initiate depressive symptoms. To what extent endometriosis patients are additionally affected by the COVID pandemic and its effects is to be determined in this study.

METHODS

Patients who presented at our endometriosis center and met the study criteria were offered participation in the study. A link to an online questionnaire (SoSci-Survey) was sent by email. The online questionnaire evaluated depressive symptoms before and during the pandemic as well as the pain perception and perceived support during the pandemic. The data of 167 fully completed questionnaires were evaluated and analyzed using SPSS.

RESULTS

The analysis of the questionnaires revealed a significant association between pain levels and depressive symptomatology in endometriosis patients during the pandemic. Patients with more severe pain showed significantly higher depressive symptoms than patients with little or no pain. During the pandemic, patients showed higher depressive symptoms than before. In addition, it was found that those endometriosis patients who felt left alone with their pain due to the consequences of the COVID pandemic, or who felt they had to endure the pain alone, also had higher depressive symptoms.

CONCLUSION

In summary, it can be observed that endometriosis patients with a high pain burden had significantly higher depressive symptoms during the COVID pandemic. The consequences of the pandemic often led to the feeling of having to cope with the symptoms alone or having to endure pain alone, which in turn increased the depressive symptoms. As treating physicians, we should be aware of these connections and try to counteract them with targeted offers and support.

Cognitive-affective changes mediate the mindfulness-based intervention effect on endometriosis-related pain and mental health: A path analysis approach

BACKGROUND

There is poor knowledge about the therapeutic mechanisms of the conservative interventions for endometriosis. We hypothesized that the effects of a brief mindfulness-based intervention (bMBI) on pelvic pain intensity (PPI), pain unpleasantness (PU) and quality of life mental health (QoL-MH) are mediated by direct and indirect paths of changes in pain catastrophizing (PC), positive affect (PA) and negative affect (NA).

METHODS

A secondary analysis of a pilot randomized controlled trial of women with endometriosis, assigned to standard medical treatment (n = 32) and standard medical treatment plus bMBI (n = 31). We tested a series of parallel and serial mediators (PC, PA and NA) of the relationship between bMBI and outcomes (PPI, PU and QoL-MH).

RESULTS

The bMBI group demonstrated improvement in PA (Cohen's f2  = 0.12 [0.01, 0.36]), decreases in NA (Cohen's f2  = 0.06 [0.00, 0.24]) and PC (Cohen's f2  = 0.16 [0.02, 0.42]). The PC reduction mediated the effect of the bMBI on PPI and PU directly; however, the PC effect through PA increase mediated the PU marginally but not PPI changes. bMBI effect on Qol-MH was mediated directly by PA and NA. The PC improved Qol-MH through PA increase and Pain decrease but not via NA.

CONCLUSIONS

Our findings showed that bMBI impacts pain through changes in pain-related cognitive-affective factors. bMBI can improve QoL-MH by multiple pathways, including but not limited to pain reduction, highlighting the independent potential of improvement in affect to restore mental health in endometriosis.

SIGNIFICANCE

Brief mindfulness-based intervention improves endometriosis pain through pain-related cognitive-affective factors and quality of life mental health via pain and affect changes unrelated to pain.

Interpretation bias in endometriosis-related pain

ABSTRACT

Endometriosis-related pain has been predominantly medically managed, which has hindered understanding of psychological factors involved in these pain experiences. Models of chronic pain highlight the biased interpretation of ambiguous information as health threat related (interpretation bias) as an important process in the development and maintenance of chronic pain. Whether interpretation bias may also be similarly implicated in endometriosis-related pain is unclear. The current study aimed to address this gap in the literature by (1) comparing interpretation biases between a sample of participants with endometriosis and a control sample of participants without medical conditions and pain, (2) exploring relationships between interpretation bias and endometriosis-related pain outcomes, and (3) exploring whether interpretation bias moderated the relationship between endometriosis-related pain severity and pain interference. The endometriosis and healthy control samples comprised 873 and 197 participants, respectively. Participants completed online surveys assessing demographics, interpretation bias, and pain-related outcomes. Analyses revealed that interpretation bias was significantly stronger among individuals with endometriosis relative to controls, with a large effect size. Within the endometriosis sample, interpretation bias was significantly associated with increases in pain-related interference, however, interpretation bias was not associated with any other pain outcomes and did not moderate the relationship between pain severity and pain interference. This study is the first to evidence biased interpretation styles among individuals with endometriosis and to show this bias is associated with pain interference. Whether interpretation bias varies over time and whether this bias can be modified through scalable and accessible interventions to alleviate pain-related interference are avenues for future research.

A qualitative investigation into the role of illness perceptions in endometriosis-related quality of life

Endometriosis is related to adverse quality of life (QoL) and wellbeing outcomes. The way in which endometriosis is perceived by individuals experiencing the condition has not been directly considered, yet illness perceptions (IPs) are predictors of QoL in several chronic conditions. This research aims to gain an understanding of the IPs held by individuals experiencing endometriosis and their impact on QoL. Semi-structured, one-to-one interviews with 30 UK-based participants sought to gain an understanding of participant experiences and perceptions linked to endometriosis. Three themes were constructed through reflexive thematic analysis: a life disrupted; lost sense of self; and complex emotional responses. Largely negative IPs were held by individuals experiencing endometriosis which, along with endometriosis-specific symptoms, fuelled fears for the future and reduced QoL. IP-based interventions may support the QoL of those experiencing endometriosis whilst effective treatment is sought.

The impact of endometriosis on dietary choices and activities of everyday life: a cross-sectional study

Introduction

Endometriosis is characterized by ectopic endometrial tissue and severe pain; frequently, women afflicted by this condition resort to non-medical interventions, such as dietary modifications. The aim of this study is to assess the impact of endometriosis on dietary patterns and quality of life.

Methods

An online survey was conducted among Italian women with endometriosis to gather self-reported demographic, clinical, dietary habit, and daily life data post-diagnosis.

Results

A total of 4,078 participants were included. Following an endometriosis diagnosis, 66% reported changes in eating habits, and 92% experienced a decline in daily life. Respondents chose dietary interventions: gluten-free (15%), anti-inflammatory (8%), Mediterranean (7.1%), or ketogenic (4%) diets, to improve health and reduce symptoms. The study revealed a shift in eating habits, with increased consumption of vegetables, fruits (10%), cereals, legumes (6.6%), and fish (4.5%), while reducing dairy products (18.4%), soy-containing foods (6.7%), and high saturated fats (8%). Eating habit changes correlated with endometriosis stages and worsened daily life. Educational level, endometriosis stages, years of symptoms, and eating habit changes linked to changes in daily life.

Conclusion

Our findings emphasize the importance of monitoring eating behaviors to prevent unhealthy habits and malnutrition in women with endometriosis. Further studies are needed to evaluate how different diets impact symptoms and enhance daily life for these individuals.

Menarche, Menstruation, Menopause and Mental Health (4M): a consortium facilitating interdisciplinary research at the intersection of menstrual and mental health

Menstrual and mental health form a close relationship that is under-appreciated in scientific research, clinical practice and social policy. This association is extremely complex, involving interactions between biology, psychology and social, political and structural influences on health and wellbeing. Research in these areas has traditionally been siloed: focusing on menstrual or mental health in isolation, or the interrelation from a limited one-dimensional perspective. We recognised the need for a more holistic and comprehensive approach that considers the complex interweaving nature of menstrual and mental health. In 2021, we established the Menarche, Menstruation, Menopause and Mental Health (4M) consortium as a tool to address this gap and to facilitate interdisciplinary research. This paper provides a comprehensive source of information about 4M for researchers and stakeholders who may be interested in joining or working with the consortium.

First live birth before surgical verification of endometriosis-a nationwide register study of 18 324 women

STUDY QUESTION

Do women with endometriosis have lower first live birth rate before surgical diagnosis than women without verified endometriosis?

SUMMARY ANSWER

Compared to reference women, the incidence of first live birth was lower in women prior to surgical verification of endometriosis irrespective of the type of endometriosis.

WHAT IS KNOWN ALREADY

Endometriosis is associated with pain and reduced fertility. The mechanism of infertility is partly explained by anatomical, endocrinological, and immunological changes. Over the past decades, the treatment of both endometriosis and infertility has evolved. Knowledge of fertility far before surgical diagnosis of endometriosis in large cohorts and of different types of endometriosis has been lacking. The diagnostic delay of endometriosis is long, 6-7 years.

STUDY DESIGN, SIZE, DURATION

Retrospective population-based cohort study focused on the time period before the surgical verification of endometriosis. All women with surgical verification of endometriosis in 1998-2012 were identified from the Finnish Hospital Discharge Register and the reference cohort from the Central Population Register. Data on deliveries, gynecological care, and sociodemographic factors before the surgical diagnosis were gathered from Finnish national registers maintained by the Finnish Institute for Health and Welfare, the Digital and Population Data Services Agency, and Statistics Finland.

PARTICIPANTS/MATERIALS, SETTING, METHODS

All women aged 15-49 years at the time of surgical verification of endometriosis (ICD-10: N80.1-N80.9) in Finland during 1998-2012 were identified (n = 21 620). Of them, we excluded women born in 1980-1999 due to the proximity of the surgical diagnosis (n = 3286) and women left without reference (n = 10) for the final endometriosis cohort of 18 324 women. From the final cohort, we selected sub-cohorts of women with isolated diagnosis of ovarian (n = 6384), peritoneal (n = 5789), and deep (n = 1267) endometriosis. Reference women were matched by age and residence and lacked registered clinical or surgical diagnosis of endometriosis (n = 35 793). The follow-up started at the age of 15 years and ended at the first birth, sterilization, bilateral oophorectomy, hysterectomy, or until the surgical diagnosis of endometriosis or corresponding index day-whichever came first. Incidence rate (IR) and the incidence rate ratio (IRR) of first live birth before the surgical verification of endometriosis with corresponding CIs were calculated. In addition, we reported the fertility rate of parous women (the number of all children divided by the number of parous women in the cohort) until the surgical verification of endometriosis. The trends in first births were analysed according to the women's birth cohort, type of endometriosis, and age.

MAIN RESULTS AND THE ROLE OF CHANCE

Surgical diagnosis of endometriosis was set at the median age of 35.0 years (IQR 30.0-41.4). Altogether 7363 women (40.2%) with endometriosis and 23 718 (66.3%) women without endometriosis delivered a live born infant before the index day (surgery). The IRs of the first live birth per 100 person-years were 2.64 (95% CI 2.58-2.70) in the endometriosis cohort and 5.21 (95% CI 5.15-5.28) in the reference cohort. Between the endometriosis sub-cohorts, the IRs were similar. The IRR of the first live birth was 0.51 (95% CI 0.49-0.52) between the endometriosis and reference cohorts. Fertility rate per parous woman before the surgical diagnosis was 1.93 (SD 1.00) and 2.16 (SD 1.15) in the endometriosis and reference cohorts (P < 0.01). The median age at the first live birth was 25.5 (IQR 22.3-28.9) and 25.5 (IQR 22.3-28.6) years (P = 0.01), respectively. Between the endometriosis sub-cohorts, women in the ovarian sub-cohort were the oldest at the time of surgical diagnosis with the median age of 37.2 years (IQR 31.4-43.3), (P < 0.001). Altogether 44.1% (2814) of the women with ovarian, 39.4% (2282) with peritoneal, and 40.8% (517) with deep endometriosis delivered a live born infant before the diagnosis. IRRs between the endometriosis sub-cohorts did not differ. Fertility rate per parous woman was lowest, 1.88 (SD 0.95), in the ovarian sub-cohort compared to 1.98 (SD 1.07) in the peritoneal and 2.04 (SD 0.96) in deep endometriosis (P < 0.001). Women with ovarian endometriosis were oldest at first live birth compared to women in other sub-cohorts with a median age of 25.8 years (IQR 22.6-29.1) (P < 0.001). Cumulative distributions of first live birth were presented according to age at first live birth and birth cohorts of the participants.

LIMITATIONS, REASONS FOR CAUTION

The increasing age at first live birth, increasing practice of clinical diagnostics, conservative treatment of endometriosis, a possible effect of coexisting adenomyosis, and use of artificial reproductive treatments should be considered when assessing the results. In addition, the study is limited due to possible confounding effects of socioeconomic factors, such as level of education. It should be noted that, in this study, we assessed parity only during the years preceding the surgical verification of endometriosis.

WIDER IMPLICATIONS OF THE FINDINGS

The need for early diagnosis and relevant treatment of endometriosis appears clear given the impairment of fertility prior to its surgical verification.

Resilience, anxiety, depression, and life satisfaction in women suffering from endometriosis: a mediation model

The main goal of this cross-sectional study was to assess the relationship between resilience and life satisfaction in women suffering from endometriosis and examine anxiety and depression as mediators in this relationship. The study sample included 349 Caucasian women aged from 18 to 56 years (M = 32.94; SD = 6.74) suffering from endometriosis surgically diagnosed and histologically confirmed. The life satisfaction level was assessed by the Satisfaction with Life Scale (SWLS). Unspecific anxiety was evaluated using the General Anxiety Disorder-7 scale (GAD-7). Depression symptoms were assessed using the Patient Health Questionnaire-9 (PHQ-9). Resilience was measured using the Resilience Assessment Scale (SPP-25). Life satisfaction correlated negatively with anxiety and depression, but positively with resilience. Resilience correlated negatively with anxiety and depression. Anxiety and resilience accounted for 25% of the life satisfaction variance. Depression and resilience explained 35% of the variance in life satisfaction. Among resilience components, personal coping skills, tolerance of negative affect, tolerance of failures and treating life as a challenge, openness to new experiences and a sense of humour, and optimistic life attitude and ability to mobilize in difficult situations were the best predictors of life satisfaction. Anxiety and depression may serve as mediators in the relationship between resilience and life satisfaction. Our results suggested that resilience may be related to life satisfaction in women suffering from endometriosis directly and indirectly as mediated by anxiety and depression.

Understanding Psychological Symptoms of Endometriosis from a Research Domain Criteria Perspective

Endometriosis is currently the second most common gynecological disease and is associated with severe pain, vegetative impairment, and infertility. In association, there are considerable psychological symptoms that limit the quality of life of those affected. In this narrative review, the Research Domain Criteria (RDoC) framework was utilized to display the different transdiagnostic processes involved in disease progression and maintenance in regard to psychosocial functioning. Using the RDoC framework, it becomes clear that immune/endocrinological dysregulation is interlocked with (pelvic) pain chronification processes and psychological symptoms such as depressive mood, loss of control, higher vigilance toward the onset or worsening of symptoms, social isolation, and catastrophizing. This paper will discuss and identify promising treatment approaches, in addition to medical care, as well as further research implications. Endometriosis can come with substantial psychosomatic and social burden, requiring more research to understand the interdependence of different factors involved in its chronic development pathway. However, it is already clear that standard care should be extended with multifaceted treatments addressing pain, as well as the psychological and social burden, in order to halt the cycle of aggravation of symptoms and to improve quality of life for patients.

Prevalence and Annual Health Insurance Cost of Endometriosis in Hungary-A Nationwide Study Based on Routinely Collected, Real-World Health Insurance Claims Data

Endometriosis is a disease that is often diagnosed late and that may lead to significant reduction in quality of life and serious complications (e.g., infertility). We aimed to assess the prevalence and the annual, nationwide health insurance treatment cost of endometriosis in Hungary using a quantitative, descriptive, cross-sectional method, focusing on the year 2019. We used claims data obtained from the Hungarian National Health Insurance Fund Administration (NHIFA). Patient numbers, total and age-specific prevalence, annual health insurance expenditure, and the distribution of costs across age groups were determined. The NHIFA spent a total of HUF 619.95 million (EUR 1.91 million) on endometriosis treatment. The highest number of patients and prevalence (10,058 women, 197.3 per 100,000) were found in outpatient care. In acute inpatient care, prevalence was substantially lower (23.5 per 100,000). Endometriosis, regardless of its type, affects 30-39-year-olds in the highest number: 4397 women (694.96 per 100,000) in this age group were affected in 2019. The average annual health insurance expenditure per capita was EUR 189.45. In addition to early detection and diagnosis of endometriosis, it is of pivotal importance to provide adequate therapy to reduce costs and reduce the burden on the care system.

Assessment of quality of life and psychological repercussions in women with endometriosis according to pain intensity

The objective is to evaluate quality of life, anxiety, and depression in women with endometriosis, and to correlate these parameters with pain intensity. This multicenter cross-sectional study was conducted on 102 women with endometriosis from 2017 to 2020. The women were divided into two groups according to the pain intensity: group 1 (severe pain, 62 women) and group 2 (mild/moderate pain, 40 women). The Endometriosis Health Profile Questionnaire, Beck Anxiety Inventory, and Beck Depression Inventory were used to assess quality of life and levels of anxiety and depression, respectively. In both groups, mean age and mean body mass index were similar (p˃ 0.5). Most women had deep endometriosis and were on treatment, but group 2 had a longer treatment time (p = 0.044). Group 1 exhibited more depression and anxiety than group 2 (17.1 ± 9.98 vs. 11.15 ± 9.25, p = 0.003 and 23.71 ± 12.92 vs 12.58 ± 10.53, p = 0.001, respectively). Women with high pain had a significantly worse quality of life than those with low pain (48.88 ± 16.02 vs. 23.32 ± 15.93, p < 0.001). Women with endometriosis and high pain intensity have a worse quality of life, and more severe levels of anxiety and depression.

Psychosocial factors associated with pain and health-related quality of life in Endometriosis: A systematic review

BACKGROUND AND OBJECTIVE

Endometriosis is associated with pain and impaired health-related quality of life (HRQoL). Psychosocial factors have been associated with pain and HRQoL in other conditions, suggesting their potential relevance in Endometriosis. However, the role of psychosocial factors in this population has not been systematically explored yet. This systematic review aims to explore the association of psychosocial factors with pain intensity/severity and HRQoL in women with Endometriosis.

DATABASES AND DATA TREATMENT

Observational and experimental studies that explored the association of psychosocial factors with pain and HRQoL in women with Endometriosis were eligible. The following databases were searched: Medline, Embase, Cochrane library, Web of Science, PsychInfo and Cumulative index of nursing and allied health literature. The methodological quality was assessed, and findings were synthesized using narrative synthesis.

RESULTS

Twenty-seven studies were eligible for inclusion, which included 5419 women with Endometriosis. Catastrophising and anxiety were the factors most consistently associated with greater pain, whilst depression, anxiety and stress were related to worse HRQoL. Findings regarding depression and pain were mixed, and research on social factors was limited.

CONCLUSIONS

This systematic review highlights the role of psychosocial factors in Endometriosis. Anxiety, depression and catastrophising are suggested as potential treatment targets. The review also indicates the lack of research on other potentially important psychosocial factors, such as avoidance, perceived injustice and social support.

SIGNIFICANCE

This systematic review explored the role of psychosocial factors in Endometriosis, suggesting that these are associated with pain and health-related quality of life (HRQoL). Among the psychosocial factors included, anxiety, depression and catastrophising were the factors most often associated with pain and HRQoL in Endometriosis. These findings highlight the need to target psychological factors in the treatment of women with Endometriosis.

Assessing the experience of dyspareunia in the endometriosis population: the Subjective Impact of Dyspareunia Inventory (SIDI)

STUDY QUESTION

Is the Subjective Impact of Dyspareunia Inventory (SIDI) a reliable tool to examine the experience of dyspareunia in the context of endometriosis?

SUMMARY ANSWER

In this study, the SIDI showed good structural and psychometric properties, and thus can be used as a reliable questionnaire to assess the impact of endometriosis-related dyspareunia on multiple dimensions, such as sexuality and intimate relationships.

WHAT IS KNOWN ALREADY

In the endometriosis population, dyspareunia has a tremendous negative impact on psychological health, overall sexual function and couple relationships. However, there is a paucity of tools that can be effectively used in either research or clinical practice to assess the subjective components of the dyspareunia experience, including coping strategies to deal with the pain.

STUDY DESIGN, SIZE, DURATION

In this cross-sectional study, the validity of the SIDI was examined by considering the responses provided by 638 participants with endometriosis and dyspareunia, who participated in an online survey conducted between 8 November and 21 December 2021. Participants were recruited using snowball sampling that involved posting the invitation to participate in the study on the social media of a patient association.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Participants were women aged ≥18 with clinical or surgical diagnosis of endometriosis. The SIDI measures the subjective impact of dyspareunia and is composed of 16 items focused on the frequency of dyspareunia-related experiences in the last 6 months, rated on a 5-point Likert scale. Sexuality was assessed using the Female Sexual Function Index. Psychological health was measured using the Hospital Anxiety and Depression Scale and the Rosenberg Self-Esteem Scale. Sociodemographic and endometriosis-related information was collected using a researcher-made questionnaire. Statistical significance was set at P < 0.05.

MAIN RESULTS AND THE ROLE OF CHANCE

Factor analysis revealed that the SIDI has a four-factor structure and allows for examining the impact of dyspareunia in terms of Sexual Concerns (Factor 1), Relationship Concerns (Factor 2), Partner Support (Factor 3) and Endurance of Pain (Factor 4). The SIDI showed good structural and psychometric properties (including internal consistency), was associated with sexual function and psychological health and was able to discriminate between participants with and without sexual dysfunction.

LIMITATIONS, REASONS FOR CAUTION

Reasons for caution are related to the risk of self-selection bias depending on the study population and recruitment strategy. Moreover, all the information provided by the participants was self-reported, which may have affected the accuracy of the data collected, especially with regards to endometriosis-specific information.

WIDER IMPLICATIONS OF THE FINDINGS

This study may provide a new brief tool that can be used by clinicians and researchers to assess the impact of dyspareunia from a multidimensional perspective and to consider subjective aspects that can be usefully integrated with information about pain severity, timing and localization.
