Estrogen and alcohol use in women: a targeted literature review.

PURPOSE: Alcohol is posited to affect sex steroid hormone concentrations, and a growing body of research has demonstrated menstrual cycle effects on women's use of alcohol. The present targeted review synthesizes the literature examining the relationship between alcohol use and estradiol in women and suggests directions for future research. METHODS: Articles were identified using the PubMed database using the following criteria: published in English, presented original findings for women, were peerreviewed, and included measures of estradiol levels in the analyses. Twenty-nine articles were identified for inclusion. RESULTS: Results from this review indicate acute alcohol use temporarily increases estradiol levels in women, and this may be strongest when gonadotropins are high. Regular alcohol use (≥1 drink per day) increases estradiol levels, but estradiol appears to be suppressed in women with alcohol use disorders and physiologic dependence. Alcohol use tends to be highest in women during ovulation, when estradiol is high, and progesterone is low. CONCLUSION: Alcohol use increases estradiol levels in women, particularly in the presence of gonadotropins. More research is needed to assess the effect of estradiol on alcohol use in women. Research on the relationship of estrogen and alcohol use in women is needed to elucidate health outcomes through the lifespan.

Association between COVID-19 vaccination and menstruation: a state of the science review.

INTRODUCTION: Menstrual health is a key patient-reported outcome beyond its importance as a general indicator of health and fertility. However, menstrual function was not measured in the clinical trials of COVID-19 vaccines. The purpose of this review was to synthesise the existing literature on the relationship between COVID-19 vaccination and menstrual health outcomes. METHODS: A PubMed search to 31 October 2023 identified a total of 53 publications: 11 prospective cohort studies, 11 retrospective cohort studies or registry-based cohort studies, and 31 cross-sectional or retrospective case-control studies. RESULTS: Identified studies were generally at moderate-to-high risk of bias due to retrospective design, interviewer bias, and failure to include a non-vaccinated control group. Nonetheless, the bulk of the literature demonstrates that COVID-19 vaccine is associated with temporary changes in menstrual characteristics (cycle length and flow) and menstrual pain. Follicular phase (at the time of vaccination) is associated with greater increases in cycle length. Evidence suggests temporary post-vaccine menstrual changes in adolescents, abnormal vaginal bleeding in postmenopausal individuals, and a potential protective effect of using hormonal contraception. CONCLUSIONS: In this review we found evidence supporting an association between the COVID-19 vaccine and menstrual health outcomes. Given the importance of menstrual function to overall health, we recommend that all future vaccine trials include menstruation as a study outcome. Future vaccine studies should include rigorous assessment of the menstrual cycle as an outcome variable to limit sources of bias, identify biological mechanisms, and elucidate the impact of stress.

Development and initial validation of the menstrual sensitivity index.

OBJECTIVE: The present study sought to develop and perform the initial validation of a scale assessing sensitivity to menstrual pain and symptoms. METHODS: Data were taken from a larger parent study in which participants were recruited from a nationwide sample of individuals via the UniVox platform (www.univoxcommunity.com). In that study, participants were stratified by age and self-reported menstrual pain. Participants in the parent study completed 2 online surveys, one at baseline and one at a 3-month follow up. Participants who provided complete responses to the potential scale items, as well as a variety of validated questionnaires, were included in the present analyses. Final item selection was determined by factor analyses, and measures of validity and reliability were examined. RESULTS: Factor analyses support an 8-item scale assessing menstrual sensitivity. This scale, the Menstrual Sensitivity Index, demonstrates excellent internal consistency, good item-total correlations, and good total score test-retest reliability. Convergent validity emerged for menstrual- and pain-specific measures, and divergent validity emerged for anxiety sensitivity, anxiety, depression, nonmenstrual bodily pain, and premenstrual symptoms. CONCLUSIONS: Menstrual sensitivity is a unique construct that reflects women's attunement to and fear of menstrual symptoms, and the Menstrual Sensitivity Index is a valid and reliable measure of this construct. This scale could be useful in advancing research and clinical work targeting menstrual pain.

Reflections on the group dynamic in a group cognitive behavioral therapy intervention for young adult women with moderate to severe dysmenorrhea: a qualitative analysis.

A recent group cognitive behavioral therapy (gCBT) intervention for dysmenorrhea conducted by our team demonstrated feasibility, acceptability, and preliminary efficacy at reducing menstrual pain. This study aimed to use qualitative analyses to explore participants' reflections about the intervention's group dynamic. Participants included 20 young women ages 18-24 years with average menstrual pain of 8.0 (SD = 1.1) on a 0-10 (0 = none, 10 = worst pain possible) numeric rating scale. Semi-structured individual and group interviews were conducted after the intervention. Researchers then conducted deductive, iterative thematic analysis using a template analysis approach. Two themes were generated: benefit and logistics. The benefit theme included two sub-themes: (1) camaraderie (an emotional, psychological, or social connection between participants); and (2) sharing (information, advice, or experiences). The logistics theme highlighted how the structure of the group influenced the dynamic and was divided into two sub-themes according to the time frame being described: (1) reactions (participants' experiences with how the group dynamic was facilitated); and (2) future (how the group structure could be improved). Results of this study contribute to the growing body of literature related to gCBT for pain conditions. Future research is needed to optimize the group dynamic and evaluate its specific therapeutic role in the treatment.

Psychiatric Symptoms Across the Menstrual Cycle in Adult Women: A Comprehensive Review.

LEARNING OBJECTIVE: After participating in this activity, learners should be better able to:• Discuss and outline the general and overlapping effects of the menstrual cycle on women's mental health. ABSTRACT: A growing body of research demonstrates menstrual cycle-dependent fluctuations in psychiatric symptoms; these fluctuations can therefore be considered as prevalent phenomena. Possible mechanisms underlying these fluctuations posit behavioral, psychological, and neuroendocrine influences. Recent reviews document cyclic exacerbation of symptoms and explore these mechanisms in the context of specific and often single disorders. The question remains, however, as to whether there are general and overlapping effects of the menstrual cycle on women's mental health. To address this gap, we synthesized the literature examining the exacerbation of a variety of psychiatric symptoms across the menstrual cycle in adult women. Results show that the premenstrual and menstrual phases are most consistently implicated in transdiagnostic symptom exacerbation. Specifically, strong evidence indicates increases in psychosis, mania, depression, suicide/suicide attempts, and alcohol use during these phases. Anxiety, stress, and binge eating appear to be elevated more generally throughout the luteal phase. The subjective effects of smoking and cocaine use are reduced during the luteal phase, but fewer data are available for other substances. Less consistent patterns are demonstrated for panic disorder, symptoms of posttraumatic stress disorder, and borderline personality disorder, and it is difficult to draw conclusions for symptoms of generalized anxiety disorder, social anxiety disorder, obsessive-compulsive disorder, and trichotillomania because of the limited data. Future research should focus on developing standardized approaches to identifying menstrual cycle phases and adapting pharmacological and behavioral interventions for managing fluctuations in psychiatric symptoms across the menstrual cycle.

Pain catastrophizing, but not mental health or social support, is associated with menstrual pain severity in women with dysmenorrhea: A cross-sectional survey.

The aim of this study was to understand the relationship between psychosocial factors, including mental health, pain cognitions and social support associated with menstrual pain severity in women with dysmenorrhea of no identified medical cause (primary dysmenorrhea; PD) and dysmenorrhea related to endometriosis. Participants included 1192 women aged 18-50 years with menstrual pain, recruited to an online cross-sectional survey in 2019. Questionnaires assessed self-reported menstrual pain severity, depression, anxiety, stress, pain catastrophizing, and social support. Women with endometriosis had significantly higher menstrual pain severity (p < 0.001) and pain catastrophizing (p < 0.001) than women with PD. Of the psychosocial factors, only pain catastrophizing (specifically, the helplessness sub-scale) predicted menstrual pain severity in each group. Overall, 36% of women with PD and 58% with endometriosis had clinically relevant levels of pain catastrophizing. Findings suggest a common psychological mechanism in women with menstrual pain, regardless of etiology. Interventions to reduce pain helplessness may be beneficial in supporting women with dysmenorrhea.

COVID-Related Distress Is Associated with Increased Menstrual Pain and Symptoms in Adult Women.

The COVID-19 pandemic resulted in heightened stress for many individuals, with women reporting more stress than men. Although a large body of evidence has demonstrated that stress, in general, can impact the menstrual cycle, it is not yet clear if COVID-specific stress would impact women's menstrual health. The current study explored the relationship between COVID-related stress and distress and menstrual variables (menstrual pain, number and severity of menstrual symptoms, and menstrual pain interference) in a sample of reproductive-age adult women. Seven-hundred fifteen women completed the initial survey and were re-contacted to complete the same survey three months later. Of those recontacted, 223 completed the follow-up survey. Results indicated that COVID-related stress and distress was associated with higher levels of menstrual pain, more frequent and more severe menstrual symptoms, and greater menstrual pain interference, even after accounting for age, hormonal use, bodily pain, and pain catastrophizing. Our findings suggest that women experience unique vulnerabilities that directly impact their health and functioning, and both research and clinical care should address these symptoms through careful assessment and treatment of menstrual pain and symptoms, particularly during and after periods of high stress and distress.

The Role of Social Media in Providing Support from Friends for Adolescent and Young Adult (AYA) Patients and Survivors of Sarcoma: Perspectives of AYA, Parents, and Providers.

Purpose: The aims of the current study were to better understand, from the perspective of adolescents and young adults (AYAs) with sarcoma, parents, and providers, the friendship support needs of AYAs with bone and soft tissue sarcoma and the role of social media in facilitating social support for AYAs with sarcoma. Methods: Semistructured interviews were conducted with 21 participants. AYA (n = 10) ranged in age from 14 to 23 years (mean 19.3, standard deviation 3.4 years; 50% female). All AYAs reported a current or past diagnosis of sarcoma, except for one patient who had another cancer diagnosis but was receiving treatment through the sarcoma clinic. Five parents of the adolescent participants were interviewed, as well as six health care providers. Data analysis was conducted using theory-driven immersion/crystallization, incorporating the Resilience in Illness Model as a framework to guide interpretation of the data. Results: Four main themes associated with social support from friends and social media were identified: (1) Social media provides a way to feel normal and connected to friends; (2) Social media accentuates the frustration of being left behind; (3) Social media facilitates the need to be understood by peers who have experienced sarcoma, and (4) Social media can lead to despair, and also provide hope for the future. Conclusions: Connecting with peers through social media can play an important role in providing support for AYAs with sarcoma, but it may also amplify feelings of frustration and anxiety. Future work is needed to determine intervention components that can maximize the benefits of social media for social support of AYAs with sarcoma. Clinical Trial Registration number: NCT03130751.

Phenotypes of Women with and Without Endometriosis and Relationship with Functional Pain Disability.

OBJECTIVE: Primary dysmenorrhea and secondary dysmenorrhea due to endometriosis share overlapping symptoms and likely demonstrate aspects of central sensitization. The present study aimed to identify distinct phenotypes of women who have dysmenorrhea with and without endometriosis to shed light on the unique mechanisms contributing to the pathogenesis of each condition. METHODS: An online survey was used to investigate the relationship between ratings of menstrual pain severity, menstrual symptoms (abdominal cramps, abdominal discomfort, low back pain, headache, body aches, bloating, nausea, diarrhea, increased bowel movements), widespread pain, and functional pain disability in a community sample of 1,354 women (aged 18-50) with menstrual pain in Australia. RESULTS: Compared with women without endometriosis, those with endometriosis had statistically significant higher menstrual pain severity (P<0.01), symptom severity and fatigue (all symptoms P<0.001, although only cramps and bloating were clinically significant), widespread pain sites (P<0.001), and functional pain disability (P<0.001, although this difference was not clinically significant). When examining symptoms by pain severity, women with severe menstrual pain were more likely to experience symptoms than women with less severe pain, regardless of the presence of endometriosis. Similar predictors of functional pain disability emerged for women with and without endometriosis, such as body aches, nausea, fatigue, and widespread pain, respectively, suggesting the presence of central sensitization in both groups. Logistic regression revealed that after accounting for menstrual pain severity (odds ratio [OR], 1.61) and duration (OR, 1.04), symptoms of bloating (OR, 1.12), nausea (OR, 1.07), and widespread pain sites (OR, 1.06) significantly predicted the presence of endometriosis. CONCLUSIONS: The findings suggest that phenotypes specific to endometriosis can be identified.

Ecological Momentary Assessment of Non-Menstrual Pelvic Pain: Potential Pathways of Central Sensitization in Adolescents and Young Adults with and without Primary Dysmenorrhea.

PURPOSE: Primary dysmenorrhea (PD; menstrual pain without an identified organic cause) has been proposed as a possible risk factor for the development of chronic pelvic pain, but the mechanism through which this process occurs is unknown. One possible mechanism is central sensitization - alterations in the central nervous system that increase responsiveness to pain leading to hypersensitivity. Repeated episodes of pain, such as those experienced over time with PD, may alter how the brain processes pain. Ecological momentary assessment (EMA; collection of data in real time in participants' natural environments) is a novel data collection method that may help elucidate pain occurring during non-menstrual cycle phases. PATIENTS AND METHODS: The current observational study assessed the feasibility and acceptability of using EMA via text messages to collect pelvic pain data during menstrual and non-menstrual cycle phases in a community sample of adolescents and young adults (AYA) aged 16-24 years with and without PD and explored occurrence rates and intensity of non-menstrual pelvic pain (NMPP) in each of these groups. RESULTS: Thirty-nine AYA with PD and 53 healthy controls reported pelvic pain level via nightly text message. Global response rate was 98.5%, and all participants reported that the EMA protocol was acceptable. AYA with PD reported higher intensity (2.0 vs 1.6 on 0-10 numeric rating scale; p=0.003) and frequency (8.7% vs 3.1% of days; p=0.004) of NMPP compared to healthy controls. CONCLUSION: The EMA protocol was feasible and acceptable. Though both the intensity and frequency of NMPP were low and at levels that would not typically warrant clinical assessment or intervention, these repeated nociceptive events may represent a potential mechanism contributing to the transition from cyclical to chronic pelvic pain in some individuals.

"Tomorrow, I'll Be Fine": Impacts and coping mechanisms in adolescents and young adults with primary dysmenorrhoea.

AIMS: To understand the experiences of adolescents and young adults with primary dysmenorrhoea through the lens of structured frameworks extant in contemporary pain literature. DESIGN: Descriptive qualitative study. METHODS: Thirty-nine adolescents and young adults (ages 16-24 years) with primary dysmenorrhoea participated in semi-structured in-person interviews. Transcripts of the interviews were analysed using deductive thematic analysis from November 2018 to April 2019. RESULTS: Two overarching themes, each with subthemes, were identified. The first theme, primary dysmenorrhoea impacts the whole person, contained the following subthemes: biological, social, and psychological. The second theme, coping mechanisms of women with primary dysmenorrhoea, contained the following subthemes: primary, secondary, and passive coping. CONCLUSION: Women experience several primary dysmenorrhoea-related impacts on their biological, social, and psychological functioning. Women employ a variety of coping mechanisms to manage their primary dysmenorrhoea pain. IMPACT: This study emphasizes the significant effects of primary dysmenorrhoea on nearly every aspect of women's lives and contributes to an understanding of the ways women cope with this pain. The findings of this study underscore the need for continued consideration of primary dysmenorrhoea as a debilitating pain process as well as the need for additional interventions to help women manage this condition.

An Open Trial of a Mind-Body Intervention for Young Women with Moderate to Severe Primary Dysmenorrhea.

OBJECTIVE: To evaluate the feasibility, acceptability, and preliminary efficacy of a mind-body intervention for moderate to severe primary dysmenorrhea (PD). DESIGN: Open trial (single arm). SETTING: Academic medical school. SUBJECTS: A total of 20 young adult women with moderate to severe primary dysmenorrhea were included across four separate intervention groups. METHODS: All participants received five 90-minute sessions of a mind-body intervention and completed self-report measures of menstrual pain, depression, anxiety, somatization, and pain catastrophizing at baseline, post-treatment, and at one-, two-, three-, and 12-month follow-up. Self-report of medication use and use of skills learned during the intervention were also collected at all follow-up points. RESULTS: Participants reported significantly lower menstrual pain over time compared with baseline. No changes in anxiety, depression, or somatization were observed, although pain catastrophizing improved over time. Changes in menstrual pain were not associated with changes in medication use or reported use of skills. CONCLUSIONS: A mind-body intervention is a promising nondrug intervention for primary dysmenorrhea, and future research should focus on testing the intervention further as part of a randomized clinical trial.

Caregiver-Child Discrepancies in Reports of Child Emotional Symptoms in Pediatric Chronic Pain.

OBJECTIVE: Pediatric chronic pain evaluation includes self-reports and/or caregiver proxy-reports across biopsychosocial domains. Limited data exist on the effects of caregiver-child discrepancies in pediatric pain assessment. In children with chronic pain, we examined associations among discrepancies in caregiver-child reports of child anxiety and depressive symptoms and child functional impairment. METHODS: Participants were 202 children (Mage=14.49 ± 2.38 years; 68.8% female) with chronic pain and their caregivers (95.5% female). Children and caregivers completed the Revised Child Anxiety and Depression Scale (RCADS) and RCADS-Parent, respectively. Children also completed the Functional Disability Inventory. Mean difference tests examined caregiver-child discrepancies. Moderation analyses examined whether associations between child self-reported anxiety and depressive symptoms and functional impairment varied as a function of caregiver proxy-report. RESULTS: Children reported more anxiety and depressive symptoms compared with their caregivers' proxy-reports (Z = -4.83, p < .001). Both informants' reports of child anxiety and depressive symptoms were associated with child functional impairment (rs = .44, rs = .30, p < .001). Caregiver proxy-report moderated associations between child-reported anxiety and depressive symptoms and functional impairment (B = -0.007, p = .003). When caregiver proxy-report was low, child self-reported anxiety and depressive symptoms were positively related to functional impairment (B = 0.28, SE = 0.07, 95% CI [0.15, 0.41], p < .001). CONCLUSIONS: Discrepant caregiver-child perceptions of child anxiety and depressive symptoms may be associated with functioning in children with chronic pain, especially when caregivers report less child internalizing symptoms. These findings highlight the need for further examination of the effects of caregiver-child discrepancies on pediatric chronic pain outcomes and may indicate targets for intervention.

Psychological and mind-body interventions for endometriosis: A systematic review.

Endometriosis is a common gynecological condition associated with debilitaing pain and poor mental health. This review examines the evidence for psychological and mind-body (PMB) interventions to improve endometriosis pain, psychological distress, sleep and fatigue. Electronic databases searched included PsychINFO, MEDLINE, CINAHL, EMBASE, Cochrane Library, Scopus, and PubMed. Inclusion criteria were women with endometriosis, and interventions that used psychological or mind-body interventions; there were no exclusion criteria regarding study design. Studies were identified and coded using standard criteria, and risk of bias was assessed with established tools relevant to the study design. A total of 12 publications relating to 9 separate studies were identified:- 3 randomized controlled trials, 1 controlled trial, 2 single-arm studies, 1 retrospective cohort study, and 2 case series. Interventions included yoga, mindfulness, relaxation training, cognitive behavioural therapy combined with physical therapy, Chinese medicine combined with psychotherapy, and biofeedback. Results indicate that no studies have yet used gold-standard methodology and, thus, definitive conclusions cannot be offered about PMB efficacy. However, the results of these pilot studies suggest that PMB interventions show promise in alleviating pain, anxiety, depression, stress and fatigue in women with endometriosis, and future well-designed RCTs including active control groups are warranted.

A Mobile-Based Mindfulness and Social Support Program for Adolescents and Young Adults With Sarcoma: Development and Pilot Testing.

BACKGROUND: Approximately 70,000 adolescents and young adults (AYA) are diagnosed with cancer each year in the United States. Sarcomas carry a particularly high symptom burden and are some of the most common cancers among AYA. Recent work has documented significant levels of unmet needs among AYA with cancer, particularly the need for psychosocial support. Mobile technology may be a cost-effective and efficient way to deliver a psychosocial intervention to AYA with cancer and cancer survivors. OBJECTIVE: The two aims of this study were to (1) develop a pilot version of a mobile-based mindfulness and social support program and (2) evaluate program usage and acceptability. An exploratory aim was to examine change in psychosocial outcomes. METHODS: Thirty-seven AYA with sarcoma or sarcoma survivors, parents, and health care providers participated in the study. Semistructured interviews were conducted with 10 AYA, parents of five of the adolescents, and six health care providers. Themes from the interviews helped to inform the development of a mobile-based mindfulness pilot program and a companion Facebook-based social support group. Twenty AYA consented to participate in a single-arm pre-post evaluation of the program; 17 downloaded the app and joined the Facebook group. Seven of these participants had participated in the semistructured interviews. Six additional health care providers consented to participate in the evaluation stage. RESULTS: On average, participants completed 16.9 of the 28 unique sessions and used the mindfulness app for a mean 10.2 (SD 8.2) days during the 28-day evaluation period. The majority of participants (16/17) engaged in the social group and posted at least one reply to the moderator's prompts. The mean number of responses per person to the moderator of the social group was 15.2 of 31 (49%, range 0%-97%). Both AYA and health care providers responded positively to the Mindfulness for Resilience in Illness program and offered useful recommendations for improvements. Exploratory psychosocial analyses indicated there were no significant differences from pretest to posttest on measures of perceived social support, mindfulness, body image, or psychological functioning. CONCLUSIONS: This study offers preliminary support for the feasibility and acceptability of a mobile-based mindfulness and Facebook-based social support program for AYA with sarcoma. The feedback from AYA and health care providers will assist in creating a fully developed intervention.

Feasibility and Acceptance Testing of a Mobile Application Providing Psychosocial Support for Parents of Children and Adolescents With Chronic Pain: Results of a Nonrandomized Trial.

Objective To conduct a single-arm pilot study assessing the feasibility and acceptability of a 30-day parent-focused mindfulness and psychosocial support mobile app intervention for parents of children with chronic pain. Methods Thirty parents completed the intervention, which included a mindfulness curriculum, peer support videos, and written psychoeducational content. Twelve healthcare providers also assessed the app and provided feedback. Feasibility was assessed by server-side documented usage on ≥50% of the days in the intervention period and completion of ≥70% of the mindfulness content. Parent and provider acceptance were assessed by ≥70% of participants rating each acceptance test question as ≥5 on a 7-point Likert scale. Parents completed measures of solicitousness, stress, mindful parenting, and resilience prior to and following the intervention. Results Feasibility results were mixed: parents completed mindfulness content on an average of 11.2 days during the intervention period, slightly under the pre-established criterion. However, parents completed an average of 72.1% of the content, which met feasibility criterion. Acceptance criteria were met for the majority of parent acceptance test questions and all of the provider acceptance test questions. Exploratory analyses of the psychosocial measures revealed significant decreases in parental solicitous behavior and perceived stress, and a significant increase in mindful parenting. Conclusions The current study extends the emerging body of research on mindfulness-based interventions for parents of children with chronic illness and suggests that it may be acceptable to deliver this content through a mobile device. Future research is needed to assess the intervention's efficacy compared to standard of care.

Experimental evaluation of central pain processes in young women with primary dysmenorrhea.

Primary dysmenorrhea (PD; menstrual pain without an underlying medical condition) is associated with enhanced pain sensitivity and temporal summation (TS) in adult women, which may reflect the presence of central pain processes. Research in this area has been limited by focusing on only adult populations and incomplete assessments of central sensitization. The current study explored both excitatory and inhibitory measures of pain processing in girls and young adult women with and without PD. Thirty-two young women with PD and 34 healthy controls underwent laboratory pain testing during each of 3 menstrual cycle phases (menstrual, ovulatory, and midluteal), which included measures of pain tolerance and threshold, TS, and conditioned pain modulation. Results indicated enhanced pain sensitivity in young women with PD as measured by heat pain tolerance and Average Pain50 (P50), compared with healthy controls. These group differences were evident at all phases of the menstrual cycle. No group differences in cold pain tolerance, TS, or conditioned pain modulation were evident at any phase of the menstrual cycle. These data suggest some evidence of central sensitization in young women with PD, although no evidence of enhanced excitatory or deficient inhibitory mechanisms were observed. Future research should focus on identifying other potential phenotypes for PD to determine those at risk of developing other pain problems.

Rates of Anovulation in Adolescents and Young Adults with Moderate to Severe Primary Dysmenorrhea and Those without Primary Dysmenorrhea.

STUDY OBJECTIVE: To evaluate rates of presumptive anovulation in eumenorrheic adolescents and young adults with moderate to severe primary dysmenorrhea and those without primary dysmenorrhea. DESIGN: Participants completed luteinizing hormone surge ovulation predictor test kits. Anovulatory cycles were defined by never receiving a positive result before the next menstrual period; participants were grouped as anovulatory if they experienced at least 1 anovulatory cycle during study participation. Participants rated daily level of menstrual pain on a 0-10 numeric rating scale. SETTING: A university-based clinical research laboratory. PARTICIPANTS: Thirty-nine adolescents and young adults (ages 16-24) with primary dysmenorrhea and 52 age-matched control girls. INTERVENTIONS AND MAIN OUTCOME MEASURES: Rates of presumptive anovulation. RESULTS: One hundred sixty-eight cycles were monitored, 29.8% (N = 50) of which were anovulatory (37.1% [39/105] vs 17.5% [11/63] of cycles in control and dysmenorrhea groups, respectively). During study participation, control girls were significantly more likely to have had at least 1 anovulatory cycle than were girls with primary dysmenorrhea (44.2% [23/52] vs 17.9% [7/39] of participants, respectively; P < .01). Cycle length and number of bleeding days between ovulatory and anovulatory cycles were similar. The primary dysmenorrhea group's maximum menstrual pain ratings did not differ between ovulatory and anovulatory cycles (4.77 and 4.36, respectively; P > .05). CONCLUSION: Our data support previous findings of increased rates of ovulation in primary dysmenorrhea. However, menstruation after anovulatory cycles can be as painful as menstruation after ovulatory cycles. These data support the idea that regular menses do not necessarily indicate that a normal ovulatory cycle has occurred. Previous implications that ovulation is necessary for the development of substantial menstrual pain are incomplete.

Experimental and procedural pain responses in primary dysmenorrhea: a systematic review.

Primary dysmenorrhea (PD) has been the focus of a number of experimental pain studies. Although a number of reviews exist, few have critically evaluated the existing body of research on PD and experimental and procedural pain. Data from 19 published research articles that include women with PD and responses to an experimental or procedural pain stimulus (or stimuli) suggest that women with PD may have elevated pain reactivity, as compared to women without PD. This pattern appears to be true across different phases of the menstrual cycle. However, there is an abundance of conflicting findings, which may be due to significant methodological issues such as inconsistent definitions of PD, wide variation in experimental pain methodologies, and inaccurate assessment of the menstrual cycle. Future research should focus on identifying specific symptoms (i.e., pain threshold ratings) to more clearly define what constitutes PD, establish reliable and valid laboratory testing protocols, and assess the menstrual cycle with greater precision.

Maternal Anxiety and Children's Laboratory Pain: The Mediating Role of Solicitousness.

There has been limited empirical examination of how parent variables such as anxiety and solicitousness collectively impact child pain response. We sought to examine the relationships among maternal anxiety, solicitous parenting, and children's laboratory anxiety and pain intensity in children with chronic pain. Participants included 80 children and adolescents (ages 8-18) with chronic pain and their mothers. Children completed questionnaires and lab pain tasks measuring their parents' solicitous parenting, pressure, cold and heat pain anticipatory anxiety and pain intensity. Using bootstrapping analysis, maternal anxiety predicted child anticipatory anxiety and pain intensity in girls with chronic pain, which was mediated by the child's report of parental solicitousness. For boys with chronic pain, maternal anxiety predicted boys' anticipatory anxiety and pain intensity, with no support for mediation. This study adds to the growing literature demonstrating the impact of maternal anxiety on children's pain. The study highlights the importance of considering parents in treatment designed to reduce children's pain.
