Patterns of menstrual cycle, menstrual pain and medication usage in young women from high- and middle-income countries.

RESEARCH QUESTION: Do patterns of the menstrual cycle, menstrual pain and the use of medication for menstrual pain differ between young women from high-income countries (HIC) and middle-income countries (MIC)? DESIGN: A multinational, multicentre, cross-sectional study using pen-and-paper questionnaires was conducted between 2016 and 2021 to assess patterns of the menstrual cycle, menstrual pain and the use of medication for menstrual pain. Various parameters were evaluated to identify high-risk factors for severe menstrual pain in women from two HIC (n = 1550) and nine MIC (n = 7139). RESULTS: From a total of 9114 young women, 4920 medical students (HIC n = 696, MIC n = 4224) and 3769 nursing students (HIC n = 854, MIC n = 2915) were included in this study. Compared with those from HIC, a significantly higher proportion of medical and nursing students from MIC reported cyclic pain (83.9% and 86.8%, respectively) and acyclic pain (33.8% and 31.9%, respectively) (both P < 0.001). Multivariate regression analysis revealed that low body mass index and early onset of menarche were independent risk factors for severe cyclic/acyclic pain among women from HIC, and a family history of menstrual pain was a risk factor for severe cyclic/acyclic pain among women from HIC and MIC. CONCLUSIONS: Differential patterns of the menstrual cycle, menstrual pain and use of medication for menstrual pain were found between young women from HIC and MIC. A proper educational programme may be necessary for these women and healthcare providers to understand the consequences of intractable cyclic/acyclic pain, in order to facilitate early detection and timely management of menstrual pain and its negative consequences, such as endometriosis.

Dysmenorrhea-Related Impact on Functioning Scale: Development and Measurement Properties for Cisgender Women and Transgender Men.

OBJECTIVES: To develop the Dysmenorrhea-related Impact on Functioning Scale (DIFS) to assess the impact of dysmenorrhea on functioning in cisgender women and transgender men and to evaluate its measurement properties. METHODS: Mixed and online design study conducted with adolescents and adult cisgender women and transgender men with dysmenorrhea. We developed the DIFS based on the International Classification of Functioning, Disability, and Health. Content validity was assessed with experts and people with dysmenorrhea. Item Response Theory developed the DIFS total score. Structural validity was assessed by exploratory and confirmatory factor analysis and internal consistency by Cronbach's α and McDonald's Ω. Construct validity and test-retest reliability were assessed by correlation between DIFS and World Health Organization Disability Assessment Schedule and intraclass correlation coefficient, respectively. Measurement error was also assessed. RESULTS: A total of 3335 people participated in the study. The DIFS is a 15-item instrument divided into "Bodily Functions" and "Daily Activities and Social Participation" sections and "Functioning" as a general factor. Internal consistency (α and Ω > 0.7) and test-retest reliability (intraclass correlation coefficient > 0.9) were adequate. No systematic error was found. Correlation was positive and strong between World Health Organization Disability Assessment Schedule and "Functioning" (r = 0.62, P ≤ .05). For the DIFS total score, higher scores indicate a greater impact of dysmenorrhea on functioning, and 44 points is the cutoff point for classifying the person with a significant impact of dysmenorrhea on functioning. CONCLUSIONS: DIFS showed excellent measurement properties for assessing the impact of dysmenorrhea on functioning for cisgender women and transgender men.

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.

Unmet menstrual needs and psychosocial well-being among schoolgirls in Northern Tanzania: baseline results from the PASS MHW study.

INTRODUCTION: Improving menstrual health among schoolgirls is essential to meeting the Sustainable Development Goals (SDGs) of good health and wellbeing (SDG 03), quality education (SDG 04), and gender equality (SDG 05). School participation and wellbeing among girls in low and middle-income countries are impacted by inadequate access to quality menstrual materials and WASH facilities, taboos around menstruation, and poor knowledge. Comprehensive evidence is needed to address these challenges and guide policy and practice. METHODS: An assisted self-completed questionnaire was used to collect socio-demographic information, menstrual-related data, and school climate data from 486 girls in four mixed-gender government secondary schools in Mwanza, Tanzania. The mean (SD) of three Menstrual Practices and Needs Scale (MPNS-36) sub-scores were calculated. Specifically, the extent to which girls perceived needs for carrying and changing menstrual material in school (transport and school environment); washing and drying menstrual material (reuse needs); and privacy and drying menstrual material in school (reuse insecurity) were met. An ANOVA test compared MPNS scores for groups, and logistic regression examined the association between menstrual health and wellbeing outcomes (self-efficacy, menstrual anxiety, school attendance, and participation) and MPNS subscale scores. RESULTS: The mean age of the 486 participants was 15.6 years (SD 1.3); 87% had started menstruating; the mean age at menarche was 14.2 years (SD 1.15). The majority (75%) of girls experienced pain during the last menstrual period, 39% had menstrual-related anxiety, and 16% missed at least one day of school due to menstruation. The mean MPNS subscale score (out of 3) for the reuse needs ranged from 1.0 to 2.1 across schools; 1.6 to 2.1 for reuse insecurity; and 0.9 to 1.8 for transport and school environment needs. The MPNS subscales had sufficient reliability (Cronbach alpha = 0.74 to 0.9). The subscales also had good construct validity with menstrual-related self-efficacy: higher scores for transport and school environment were associated with confidence to seek menstrual support, participate in class, and predict when periods were about to start. CONCLUSIONS: Schoolgirls have unmet needs related to transporting and using menstrual material in school, and these needs differed across schools in northern Tanzania. Menstrual-related pain remains a major reason for poor school attendance and participation. Interventions to address menstrual practice needs in schools are required and should include a strong pain management component.

The effect of listening to music and drawing on coping with dysmenorrhea complaints in nursing students: randomized controlled trial.

AIM: To examine the effect of listening to music and drawing on coping with dysmenorrhea complaints of nursing students. METHODS: The study was a double-blind, three parallel-group randomized controlled trial conducted between August 2023 and May 2024 at Bartin University, Faculty of Health Sciences, Department of Nursing. Ninety-six dysmenorrheic nursing students with regular menstrual cycles were included in the study and randomly assigned to three groups as drawing, music and control groups. Visual Analog Scale (100mmVAS of pain), Perceived Stress Scale (PSS) and Menstrual Symptoms Scale (MSS) were applied to the students at baseline, 1st and 2nd months. The interventions were as follows: the music group listened to a 29-minute and 32-second song three days before menstruation and on the first day of menstruation in the third month composed by Juan Sebastian Martin-Saavedra, while the drawing group created art for the same duration. The pain scores, perceived stress, and menstrual symptoms were measured in all groups after the interventions. RESULTS: Pretest, 1st and 2nd months 100mmVAS of pain score averages were 7.16 ± 1.99, 7.16 ± 1.99 and 7.50 ± 1.98 for the control group, 7.22 ± 1.64, 4.84 ± 1.80 and 2.13 ± 1.45 for the music group and 6.69 ± 1.80, 5.09 ± 1.55 and 2.91 ± 1.33 for the drawing group, respectively. Pretest, 1st and 2nd months PSS score averages were 28.75 ± 3.71, 29.09 ± 3.87 and 30.03 ± 4.16 for the control group, 29.91 ± 3.98, 14.06 ± 4.06 and 3.59 ± 3.82 for the music group and 27.38 ± 3.63, 18.13 ± 5.60 and 8.34 ± 5.46 for the drawing group, respectively. Pretest, 1st and 2nd months MSS score averages were 79.25 ± 15.41, 88.00 ± 20.08 and 90.66 ± 19.13 for the control group, 85.41 ± 10.77, 62.41 ± 15.23 and 34.00 ± 12.62 for the music group and 80.69 ± 11.07, 65.53 ± 15.37 and 47.31 ± 15.11 for the drawing group, respectively. Mean menstrual pain intensity, mean perceived stress level, and mean menstrual symptoms level in the art and music group decreased significantly at 1st and 2nd months post-intervention (p < .001). A significant increase in score levels was observed in the control group. CONCLUSIONS: Both art and music practices are effective in significantly reducing menstrual pain, perceived stress, and menstrual symptoms in nursing students with dysmenorrhea. It is important to include listening to music and drawing on women's health and disease nursing practices to control menstrual pain, perceived stress, and menstrual symptoms in dysmenorrhea.

Prevalence, pain intensity and symptoms associated with primary dysmenorrhea: a cross-sectional study.

BACKGROUND: Primary dysmenorrhea (PD) is an etiological cyclic pelvic pain related to the menstrual period; it can negatively impact women's quality of life and productivity. The aim of the present study was to estimate the prevalence of PD and analyze associated symptoms in Brazilian women. METHODS: An online cross-sectional study was carried out in Brazil, with a structured questionnaire regarding dysmenorrhea and associated symptoms. PD intensity was measured with the Numerical Rating Scale for Pain and classified as mild (1-3), moderate (4-7) and severe (> 8). The association between qualitative variables was performed using Pearson's Chi-Square Test. The quantification of this association was measured using multinomial logistic regression models, with calculation of Odds Ratio and confidence interval. A significance level of 5% was considered. RESULTS: A total of 10,070 women were included. Most participants classified PD intensity as moderate (40.4%, 41.9% and 49.7%) and severe (21.2%, 24.8% and 28.4%) in the previous month, 3 months and 5 years, respectively. The most common symptoms associated with PD were irritability, abdominal distension sensation, anxiety and feeling more emotional. The increased of the risk (OR > 1.0) for moderate and severe PD-related pain intensity is related to age, nulliparity and presence PD since adolescence. CONCLUSION: There is a high prevalence of PD among Brazilian women, and the most common symptoms reported were irritability, abdominal distension sensation, anxiety and feeling more emotional.

Longitudinal associations of menstrual characteristics with mental health problems among Chinese girls.

Cross-sectional studies indicate that menstrual problems are related to poorer mental health; however, longitudinal studies are limited. This longitudinal study aimed to determine whether baseline menstrual characteristics were risk factors for incident and persistent mental health problems. The study was conducted among Chinese adolescent girls. Menstrual characteristics including menarche, menstrual cycle and menstrual pain were assessed at baseline, whereas mental health problems including PTSD, depression, anxiety, ADHD, insomnia, psychotic-like experiences, non-suicidal self-injury, suicide ideation, suicide plan, and suicide attempt were assessed at baseline (n = 1039) and at the 1-year follow-up (n = 946) by self-administered, structured questionnaires. Multiple logistic regressions were performed to examine whether menstrual characteristics were associated with incident (e.g., PTSD at follow-up but not baseline) and persistent (e.g., PTSD at both time points) mental health problems. The results demonstrated that early menarche was related to persistence of psychotic-like experiences; irregular menstruation was associated with higher rates of incident anxiety and insomnia, and persistent depression, anxiety, ADHD, insomnia, non-suicidal self-injury, suicide ideation, and suicide plan; menstrual pain was associated with elevated rates of incident PTSD and depression, and persistent depression, insomnia, psychotic-like experiences, non-suicidal self-injury, suicidal ideation, suicide plan, and suicide attempt. In conclusion, irregular menstruation and menstrual pain specifically contributed to the development of emotional problems and insomnia, and were associated with maintenance of the most mental health problems in early adolescence. The long-term effects of menstrual problems on mental health need further study.

A pilot longitudinal study of decrease in cognitive functions during the most painful day of the period among women with primary dysmenorrhea.

PURPOSE: Painful menstruation is a common problem associated with many limitations in day-to-day functioning. There is limited research on the temporary effects of menstrual pain on cognitive functioning. METHODS: A longitudinal pilot study was conducted. A group of 32 women was tested with the Brief Test of Adult Cognition by Telephone (BTACT), which consists of 7 tests measuring various cognitive functions. Participants were tested both on a regular, pain-free day and the most painful day of their period. RESULTS: The subjects displayed significantly lower results in several domains of cognitive functions during measurement on the most painful day of the period. We observed a decline in inhibitory and cognitive control, attention functioning and processing speed. CONCLUSIONS: The results provide tentative evidence for experiencing cognitive difficulties under the influence of menstrual pain and may contribute to raising awareness about related difficulties.

Measurement properties of patient-reported outcome measures for women with dysmenorrhea: A systematic review.

BACKGROUND: Dysmenorrhea, or menstrual pain, is a subjective experience, and can only be assessed by patient-reported outcomes. These instruments should be reliable, valid and responsive. AIM: To identify and critically appraise the available evidence for the measurement properties of specific patient-reported outcome measures used for dysmenorrhea. METHODS: The PRISMA statement was used to report this systematic review. Databases searched were PubMed, SCOPUS, CINAHL, Web of Science, ScienceDirect and Google Scholar (April 2021; updated on February 2023). Original studies with primary data collection, with no restriction on language and publication date that reported psychometric properties of one or more dysmenorrhea-related patient-reported outcome measure. The literature searches, selection of studies, data extraction and assessment of the risk of bias were performed independently by two reviewers and followed the COSMIN guidelines. RESULTS: Thirty studies were analysed in this review, and 19 patient-reported outcome measures were evaluated. The instruments varied in relation to the measured construct and measurement properties (validity, reliability and responsiveness). The methodological quality of the studies and the quality of evidence of the patient-reported outcome measures were variable. Among the 13 studies that reported the development of patient-reported outcome measures, most had inadequate methodological quality, and the overall rating was insufficient or inconsistent. CONCLUSIONS: The Dysmenorrhea Symptom Interference (DSI) scale was the only identified patient-reported outcome measure that has the potential to be recommended because of its sufficient rating combined with moderate quality of evidence for content validity. Future studies should further evaluate the measurement properties of the existing patient-reported outcome measures, or develop new patient-reported outcome measures following the COSMIN methodology. PATIENT OR PUBLIC CONTRIBUTION: Not applicable as this is a systematic review. TRIAL REGISTRATION: PROSPERO protocol: CRD42021244410. Registration on April 22, 2021.

"You're Not Alone": How Adolescents Share Dysmenorrhea Experiences Through Vlogs.

Many adolescents experience severe pain during menstruation, yet their attempts to receive medical attention to alleviate or manage this pain are often met with dismissal or disbelief. In light of these barriers to care, many adolescents turn to social media to share their experiences with menstruation and pain, as well as hear from other members of their community. In this study, we investigated how adolescents present their experiences with menstruation in vlogs (or "video blogs"). Using critical qualitative methods and a four-column analysis structure, we transcribed and thematically analyzed the audio and video content of 17 YouTube vlogs wherein adolescents described their experiences with menstrual pain. We found that stylistically, the vloggers modulated between a polished documentary style and an intimate storytime style of video production. We additionally found that vloggers spoke about their menstrual pain experiences from three perspectives: as a Patient managing and diagnosing physical symptoms, as a Self considering how the pain affects their life and ambitions, and as a Teacher educating their audience. Considering both the visual and audio data, we discuss how healthcare providers can use these findings to inform their approach to discussing menstrual pain with adolescents. We further discuss possible future directions for research into health story sharing on social media.

Debilitating lower back pain during menses unexpectedly resolved after treatment of subclinical temporomandibular disorder: a case report.

This case report describes a patient in whom debilitating lower back pain that always occurred during menses resolved when she received treatment for subclinical temporomandibular disorder (TMD). The patient was diagnosed with subclinical TMD and facial myalgia based on the results of clinical and radiographic examinations. She was treated with maxillary (nighttime) and mandibular (daytime) dental orthotics to provide stabilization and decompression of the temporomandibular joints. After 12 weeks of appliance therapy, which resulted in resolution of the TMD symptoms, the patient reported that the debilitating lower back pain she experienced during menses had ceased. Her back pain did not return after the use of the mandibular appliance was discontinued. The authors discuss how neurologic, postural, inflammatory, and qi flow changes attributed to the patient's TMD treatment may have contributed to the cessation of the patient's menses-related lower back pain.

Menstrual Status Is Associated with the Prevalence of Irritable Bowel Syndrome in a Japanese Young Population: A Cross-Sectional Study.

INTRODUCTION: There is evidence regarding the association between dysmenorrhea and irritable bowel syndrome (IBS), although it is lacking in the Asian population. Therefore, the purpose of this study was to investigate the association between menstrual status and IBS in a young Japanese. METHODS: Overall, 4,693 female college students were included in the analysis of this study. Information regarding lifestyle habits, menstrual status (irregularity, pain severity, and medication), and IBS (Rome III criteria) was obtained using a self-reported questionnaire. Age, body mass index, exercise habits, smoking, drinking habits, and anemia were analyzed as potential confounders. RESULTS: The prevalence of IBS was 6.1%. Moderate {adjusted odds ratio (OR): 1.89 (95% confidence interval [CI]: 1.27-2.91)} and heavy (adjusted OR: 2.14 [95% CI: 1.42-3.45]) menstrual pain were independently positively associated with IBS (p for trend = 0.001). Using medication sometimes (adjusted OR: 1.41 [95% CI: 1.09-1.84]) and often (adjusted OR: 1.60 [95% CI: 1.13-2.24]) was independently positively associated with IBS. There was no association between menstrual cycle and IBS. In subjects without functional dyspepsia, irregular menstrual cycle was independently positively associated with IBS. CONCLUSION: In the young Japanese population, menstrual pain and medications for menstrual pain may have a significant positive association with IBS.

Effects of therapeutic exercise in primary dysmenorrhea: an umbrella and mapping review.

PURPOSE: Primary dysmenorrhea (PD) is 1 of the most prevalent gynecologic conditions. The main aim of this umbrella review was to assess the effects of therapeutic exercise (TE) on PD. METHODS: A systematic search was carried out in PubMed, Embase, SPORTDiscus, CINAHL, and PEDro (December 10, 2022). The outcome measures assessed were menstrual pain intensity, menstrual pain duration, and quality of life. Methodological quality was analyzed using the AMSTAR and ROBIS scales, and the strength of evidence was established according to the advisory committee grading criteria guidelines. RESULTS: Nine systematic reviews were included. The results showed that TE, regardless of the exercise model and intensity, has a clinical effect in improving menstrual pain intensity in women with PD with moderate quality of evidence. In addition, the results showed that TE has a clinical effect in improving the duration of menstrual pain in women with PD with a limited quality of evidence. However, the results are controversial on the improvement of quality of life in women with PD with a limited quality of evidence. CONCLUSIONS: TE seems an effective option to implement in women with PD to improve the intensity and duration of menstrual pain. We cannot draw robust results for quality of life due to the low number of primary studies. More research in this field can help us establish more robust conclusions, as well as to assess whether there is one exercise model or intensity of training that is more effective than others.PROSPERO number: This review was previously registered in PROSPERO (CRD42022371428).

Efficacy of psychological interventions for dysmenorrhea: a meta-analysis.

Dysmenorrhea is pelvic pain associated with menstruation and is one of the most common pain conditions among reproductive-age women. It is commonly treated with medications, complementary and alternative medicine, and self-management techniques. However, there is increased focus on psychological interventions which modify thoughts, beliefs, emotions, and behavioral responses to dysmenorrhea. This review examined the efficacy of psychological interventions on dysmenorrhea pain severity and interference. We conducted a systematic search of the literature using PsycINFO, PubMed, CINHAL, and Embase. A total of 22 studies were included; 21 examined within-group improvement (ie, within-group analysis) and 14 examined between-group improvement (ie, between-group analysis). Random-effects meta-analyses were conducted on pain severity and interference, with average effect sizes calculated using Hedges's g. Within-group analyses showed decreased pain severity and interference at post-treatment (g = 0.986 and 0.949, respectively) and first follow-up (g = 1.239 and 0.842, respectively). Between-group analyses showed decreased pain severity at post-treatment (g = 0.909) and decreased pain severity and interference at first follow-up (g = 0.964 and 0.884, respectively) compared to control groups. This review supports the efficacy of psychological interventions for dysmenorrhea, but conclusions are tempered by suboptimal methodological quality of the included studies and high heterogeneity across studies. Additional, rigorous research is needed to determine the clinical utility of psychological interventions for dysmenorrhea.

A Rare Secondary Dysmenorrhea Resulted from Separation of Corpus Uteri from Cervix: A Case Report and Literature Review.

Secondary dysmenorrhea is a pain associated with disease such as endometriosis, pelvic inflammatory disease, leiomyomas, and interstitial cystitis. Treatment of secondary dysmenorrhea always focuses on the causative pelvic pathology or medical condition. Here, we found a rare case with secondary dysmenorrhea that resulted from traumatic separation of the uterine corpus from the cervix. In this case, the patient experienced a childhood blunt trauma of the pelvic crush and was successfully diagnosed by magnetic resonance imaging and 3-dimensional ultrasonography. Moreover, laparoscopic anastomosis could be a minimally invasive way to resolve this problem.

Effectiveness of auricular acupoint therapy targeting menstrual pain for primary dysmenorrhea: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Primary dysmenorrhea (PD) is a global public health concern affecting women's health and quality of life, leading to productivity loss and increased medical expenses. As a non-pharmacological intervention, auricular acupoint therapy (AAT) has been increasingly applied to treat PD, but the overall effectiveness remains unclear. AIMS: The aim of this review was to synthesize the effects of AAT targeting menstrual pain among females with PD. METHODS: Eight databases (PubMed, EMBASE, AMED, CINAHL Plus, Cochrane Library, Web of Science, China National Knowledge Infrastructure and Wanfang Data) and three registries (ClinicalTrials.gov, ISRCTN Registry and the Chinese Clinical Trial Registry) were searched to identify existing randomized controlled trials (RCTs) from inception to 21 August 2022. Two reviewers independently screened, extracted the data, and appraised the methodological quality and the evidence strength using the Cochrane risk-of-bias tool for randomized trials (RoB 2) and the GRADE approach. RESULTS: A total of 793 participants from 11 RCTs were included. Despite substantial heterogeneity, AAT was more effective in reducing menstrual pain and related symptoms than placebo and nonsteroidal anti-inflammatory medications (NSAIDs). No significant subgroup differences were found between study locations as well as invasiveness, duration, type, acupoints number, ear selection and provider of AAT. Only minor adverse effects of AAT were reported. LINKING EVIDENCE TO ACTION: AAT can help women with PD, particularly those who are refrained from pharmaceuticals. Primary healthcare professionals, including nurses, can be well-equipped to provide evidence-based and effective AAT for people with PD. AAT can be used in a broader global clinical community. To provide an optimal effect and have wider usability, a unified practice standard is required, which would necessitate further adaptation of clinical care of people with PD. AAT effectively decreased menstrual pain and other accompanying symptoms of PD. More research is needed to identify effective AAT features and explore optimal therapy regimes for PD.

A targeted educational programme improves fundamental knowledge of menstrual pain and endometriosis in young women: The Endometriosis Awareness Promotion Project.

RESEARCH QUESTION: Would a properly designed educational programme offered to young women improve their awareness and fundamental knowledge of menstrual pain and endometriosis? DESIGN: A multinational cross-sectional study using a pen-and-paper questionnaire among women aged 19-24 years was conducted between 2017 and 2019 to assess fundamental knowledge of menstrual pain and endometriosis. Improvement in knowledge was also analysed using a separate questionnaire completed before, and 1-3 months after, a group discussion, lecture on menstrual pain and endometriosis, or both. RESULTS: Among three groups of students (college [n = 271], medical [n = 877] and nursing [n = 763]), knowledge of menstrual pain and endometriosis was lowest among college students, modest among nursing students and fair among medical students (P < 0.001 for each). The experience of cyclical pain, even when painkillers were taken, was reported by 15.5%, 4.6% and 3.8% of students, respectively. Most students managed their cyclical pain by enduring it or by taking over-the-counter medication. An informative education programme with group discussions, lectures, or both, was successful in improving knowledge and consequences of menstrual pain and endometriosis. Proper education and dissemination of knowledge to college students failed to motivate them to visit gynaecologists; however, medical and nursing students became highly interested in visiting gynaecologists. CONCLUSIONS: An educational programme can improve awareness and knowledge of endometriosis and dysmenorrhoea among young women. The programme motivated nursing and medical students, but not college students, to seek medical attention for early detection and management of endometriosis.

Development of a scale to evaluate negative menstrual attitudes among Nepalese women.

BACKGROUND: Menstrual attitudes include negative and positive perceptions of menstruation and are associated with reproductive health, underscoring the importance of its evaluation in women. Given that social and cultural factors affect menstrual attitudes, developing evaluation methods specific to distinct societal cultures is necessary. METHODS: We developed a scale based on the menstrual attitude questionnaire, which is the most widely used measure of menstrual attitudes, to evaluate negative menstrual attitudes among Nepalese women in consideration of Nepalese cultural backgrounds and literacy. In total, 352 Nepalese women aged 20-45 years living in urban or suburban areas in Nepal were enrolled in the study. Participants were randomly divided into two groups using the permuted block method. Using the prototype, Group 1 (n = 176) was evaluated with an exploratory factor analysis to develop a reliable scale, and Group 2 (n = 176) was evaluated with a confirmatory factor analysis to confirm the structure of negative menstrual attitudes. Further, we preliminarily examined the relationship of negative menstrual attitudes with the frequency of traditional menstrual practices and intensity of menstrual pain, which are significant reproductive health issues in Nepal, in Group 2. RESULTS: We developed a 15-item, 3-factor scale to evaluate negative menstrual attitudes among Nepalese women using exploratory factor analysis. The first, second, and third factors were "Natural event" (α = 0.82), "Debilitating event" (α = 0.76), and "Bothersome event" (α = 0.69), respectively. Confirmatory factor analysis revealed that negative menstrual attitudes comprised a 3-factor structure. Participants who performed three traditional menstrual practices ("stay in their own house", "go to public spaces", and "contact with others generally") demonstrated significantly higher scores for negative menstrual attitudes than did non-performers. Negative menstrual attitudes were positively correlated with the intensity of menstrual pain (r = 0.558). CONCLUSIONS: This study is the first to evaluate menstrual attitudes and analyse its factor structure among Nepalese women. In the future, the relationship between accurately evaluated negative menstrual attitudes and reproductive health issues should be examined more comprehensively.

For sexually mature women, menstruation may be considered burdensome, but its absence may also be a source of concern. Perceptions regarding menstruation are collectively referred to as menstrual attitudes. Previous studies have reported that negative menstrual attitudes are associated with various reproductive health issues in women and vary according to social and cultural backgrounds. To adequately evaluate negative menstrual attitudes among Nepalese women (20­45 years old), we developed a 15-item scale that considers their cultural background and literacy. We observed that attitudes toward menstruation among Nepalese women consisted of three emotions: one positive emotion, including "menstruation is a natural phenomenon", and two negative emotions, including "menstruation is debilitating" and "menstruation is bothersome". In several developing countries, menstruating women are considered unclean, and various restrictions are imposed on women during menstruation (traditional menstrual practices). Nepalese women with strong negative menstrual attitudes, as assessed by our scale, engaged in several traditional menstrual practices with higher frequency. We also observed that women with more negative menstrual attitudes presented with more severe menstrual pain. Our scale was developed to be compatible with the values and literacy of Nepalese women and was easy to answer. We believe that reducing negative emotions toward menstruation will contribute to reducing the frequency of traditional menstrual practices and menstrual pain, thereby facilitating school attendance and entry into the workforce among women in Nepal.

Decreased dysmenorrhea pain in girls by reducing oxidative stress and inflammatory biomarkers following supplementation with oleoylethanolamide: A randomized controlled trial.

AIM: This study aimed to evaluate the oleoylethanolamide (OEA) effects on oxidative stress and inflammatory factors in girls with primary dysmenorrhea. METHODS: This double-blind, placebo-controlled clinical trial was done on population consisted of female students who had dysmenorrhea pain based on the visual analogue scale (VAS) questionnaire. Patients were randomly allocated to groups consuming a capsule containing 125 mg of OEA per day (n = 22) or placebo (n = 22) for 2 months. The severity of the pain, total antioxidant capacity (TAC), malondialdehyde (MDA), C-reactive protein (CRP), and tumor necrosis factor alpha (TNF-α) were measured at the beginning and the end of the study. In this study, SPSS software was used to analyze the data. RESULTS: According to the results, oral supplementation with OEA for 60 days significantly increased TAC (p = 0.022) and decreased the menstrual pain (p = 0.040), MDA (p = 0.011), CRP (p = 0.01), and TNF-α (p = 0.038) compared to the placebo group. Also, intragroup changes were statistically significant on the mean of pain (p = 0.042), TAC (p = 0.032), MDA (p = 0.023), CRP (p = 0.027), and TNF-α (p = 0.029) at the end of the study in the intervention group. Changes in the studied factors at the end of the study compared to the beginning of the study in the placebo group were not statistically significant. CONCLUSION: Considering the reducing effects of OEA on menstrual pain, using of this supplement can be introduced as an alternative medicine to reduce the use of anti-inflammatory drugs.

The effect of Dioscorea esculenta powder on prostaglandin E2 and cytochrome c oxidase subunit 2 levels, menstrual pain, and premenstrual syndrome in young women: A randomized double-blind controlled trial.

Background Diosgenin, extracted from Dioscorea esculenta, has been reported to decrease prostaglandin E2 (PGE2) levels and any other inflammatory cytokine in rodents. However, it is still unclear whether D. esculenta intake suppressed PGE2 production and menstrual pain and premenstrual syndrome (PMS) in younger female. Aim This study aims to investigate the effect of D. esculenta intake on PGE2 and cytochrome c oxidase subunit 2 (COX-2) levels and on menstrual pain and PMS in young women. This is a randomized, double-blind, placebo-controlled, crossover study. Methods Ten healthy young females were administered either a placebo or D. esculenta (300 mg/day) for 4 weeks, followed by a 4-week washout period. Fasting blood sample was taken from the fingertips on the second day of menstrual cycle began and obtained 24h before the last D. esculenta to avoid acute effects. Participants then switched treatments for 4 weeks as a second trial. Plasma PGE2 and COX-2 levels were measured before and after each trial. The visual analogue scale (VAS), McGill pain questionnaire (MPQ), and Daily Record of Severity of Problems (DRSP) were also evaluated. The study was set and conducted from 2019 to 2020. Results PGE2 and COX-2 levels significantly decreased after D. esculenta intake compared to placebo (p = 0.038, p = 0.042 each). The VAS and DRSP scores were also significantly lower after D. esculenta intake (p = 0.046, p = 0.035 each). Conclusion Four-week D. esculenta intake suppressed PGE2 and COX-2 levels resulting in an improvement in PMS symptoms and menstrual pain in young women.
