Primary dysmenorrhea in adolescents: Association with attention deficit hyperactivity disorder and psychological symptoms

Prevalence of chronic pelvic pain and associated factors among indigenous women of reproductive age in Ecuador

BACKGROUND

Chronic pelvic pain is a common disease that affects approximately 4% of women of reproductive age in developed countries. This number is estimated to be higher in developing countries, with a significant negative personal and socioeconomic impact on women. The lack of data on this condition in several countries, particularly those in development and in socially and biologically vulnerable populations such as the indigenous, makes it difficult to guide public policies.

OBJECTIVES

To evaluate the prevalence of chronic pelvic pain (dysmenorrhea, dyspareunia, non-cyclical pain) and identify which variables are independently associated with the presence of the condition in indigenous women from Otavalo-Ecuador.

DESIGN

A cross-sectional study was carried out including a sample of 2429 women of reproductive age between 14 and 49 years old, obtained from April 2022 to March 2023. A directed questionnaire was used, collected by bilingual interviewers (Kichwa and Spanish) belonging to the community itself; the number of patients was selected by random sampling proportional to the number of women estimated by sample calculation. Data are presented as case prevalence, odds ratio, and 95% confidence interval, with p < 0.05.

RESULTS

The prevalence of primary dysmenorrhea, non-cyclic pelvic pain, and dyspareunia was, respectively, 26.6%, 8.9%, and 3.9%.all forms of chronic pain were independently associated with each other. Additionally, dysmenorrhoea was independently associated with hypertension, intestinal symptoms, miscegenation, long cycles, previous pregnancy, use of contraceptives and pear body shape. Pain in other sites, late menarche, exercise, and pear body shape were associated with non-cyclic pelvic pain. And, urinary symptoms, previous pregnancy loss, miscegenation, and pear body shape were associated with dyspareunia.

CONCLUSION

The prevalence of primary dysmenorrhea and non-cyclical chronic pelvic pain was notably high, in contrast with the frequency of reported dyspareunia. Briefly, our results suggest an association between dysmenorrhoea and conditions related to inflammatory and/or systemic metabolic disorders, including a potential causal relationship with other manifestations of pelvic pain, and between non-cyclical pelvic pain and signs/symptoms suggesting central sensitization. The report of dyspareunia may be influenced by local cultural values and beliefs.

A multidimensional appraisal of early menstrual pain experience

BACKGROUND

Symptomatic dysmenorrhea is a global problem, affecting more than 40% of menstruating persons. Cross-sectional studies have implicated psychosocial, biological, and sensory factors in dysmenorrhea but the mechanisms are not fully understood. Only a few prospective longitudinal studies have evaluated such factors in relation to the emergence and course of dysmenorrhea at menarche.

OBJECTIVE

This study aimed to describe the initial menstruation experience and to evaluate the association of premenarchal psychosocial and sensory factors with the intensity of dysmenorrhea during the period in the fourth month.

STUDY DESIGN

This was a prospective cohort study of adolescents who completed premenarchal assessments and postmenarchal daily menstrual diaries for their first (n=149) and fourth month periods (n=114). They were recruited shortly before menarche and completed baseline assessments, including psychosocial questionnaires and experimental pain sensitivity (pressure testing, bladder provocation), and their parents completed related pain questionnaires. The relation between the hypothesized premenarchal factors and month 4 dysmenorrhea intensity was evaluated using Kruskal-Wallis and chi-square tests for low (<3 on a 0-10 scale) vs higher (≥3) menstrual pain groups based on maximal pain ratings recorded in a daily diary.

RESULTS

Low levels of dysmenorrhea characterized the first (median, 1; interquartile range, 0-2) and fourth month periods (1; 0-3). Maximal pain ratings increased from the first to the fourth period (3; 1-5 vs 4; 1-6; P=.007). The distribution of dysmenorrhea was multimodal at month 4 with 31.6% of the participants having low levels of maximal pain (1; 0-1) and 68.4% having higher levels (5; 4-6; Hartigan's dip test P<.001). The baseline demographic, psychosocial, and parental pain characteristics were not associated with the development of worse dysmenorrhea. The baseline experimental pain sensitivity, based on pressure pain thresholds, did not differ between the low (15.7 N; 12.5-22.3) and higher (15.0 N; 10.9-21.4]) level dysmenorrhea groups. Baseline bladder pain at first urge also did not differ (low, 6; 0-20 vs higher, 7; 0-19).

CONCLUSION

By their fourth month period, two-thirds of adolescents fell into the higher group for maximal dysmenorrhea, half reported some related impairments in physical activity, and one-seventh reported some related school absence. Premenarchal factors (experimental pain sensitivity, psychosocial profile, parental pain experience) linked to chronic pain emergence in the adult literature did not predict dysmenorrhea intensity, suggesting the dominant factor at menarche may be peripheral afferent activation. Further research is needed to understand the evolution of psychosocial and sensory mechanisms in the development and course of dysmenorrhea.

Perceived associations between the menstrual cycle and Attention Deficit Hyperactivity Disorder (ADHD): A qualitative interview study exploring lived experiences

BACKGROUND

The research gap regarding Attention Deficit Hyperactivity Disorder (ADHD) in people who were assigned female at birth has led to a lack of knowledge and adequate approaches in clinical practice, as well as diagnosis processes. Recent studies report potential associations between reproductive hormones and ADHD, but existing research remains scarce.

AIM

This study aims to explore the experiences of people who perceive an association between their menstrual cycle and their ADHD symptoms.

METHODOLOGY

Design and Method. A qualitative research design with an inductive approach was used. Ten participants were interviewed, using semi-structured, in-depth interviews. The data was transcribed, coded, and analyzed using reflexive thematic analysis according to Braun and Clarke.

RESULTS

Findings show participant's perceived associations between their ADHD and their menstrual cycle: participants reported experiencing ADHD symptom mor severe during the mid-luteal phase of the menstrual cycle. Other results showed uncertainty around ADHD medication in relation to the cycle and varied experiences with health care encounters as well as heightened challenged around menstrual health management.

CONCLUSIONS

This study provides insights to how perceived associations between ADHD and the menstrual cycle might be experienced. This report highlights the need for further research and theory about the potential associations between ADHD and reproductive hormones. The researchers strongly suggested that forthcoming ADHD studies consider times of key hormonal changes, such as puberty and menarche, menopause, hormonal birth control, pregnancy, hormone treatment, and more.

Instruments to Identify Menstrual Complaints and Their Impact on Adolescents: A Systematic Review

STUDY OBJECTIVE

The aim of this review was to create an overview of available instruments used to evaluate the menstrual complaints of dysmenorrhea and heavy menstrual bleeding (HMB) in adolescents.

METHODS

The search was conducted in PubMed, Web of Science, Embase, and PsycINFO on December 1, 2022. Studies published in English reporting on menstrual complaints among girls aged 10-19 were included. The quality and bias risk was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2.

RESULTS

Of 8994 identified studies, 57 were included. In these studies, 19 instruments were described, of which 8 were validated in adolescents. One was difficult to use in daily practice, 1 had low sensitivity and specificity in the detection of HMB, 2 were validated by face validity, and 2 were not specifically developed to evaluate (the impact of) menstrual complaints. Therefore, only 2 were validated and feasible to measure adolescent menstrual complaints: the Period ImPact and Pain Assessment (PIPPA) and the Adolescent Menstrual Bleeding Questionnaire (aMBQ). Remarkably, the Pictorial Blood Loss Assessment Chart (PBAC) was the most frequently used instrument in adolescents. There was one modified version of the PBAC for adolescents, which had a lower cutoff value for HMB and low sensitivity and specificity.

CONCLUSION

We found that the PIPPA and aMBQ are suitable for assessing menstrual complaints and their impact on daily activities and health-related quality of life in adolescents. The PBAC, which is used frequently in adults, needs to be further assessed specifically for adolescents. In particular, the clinical relevance of the PBAC cutoff value for HMB should be determined for this age group. Considering the different interpretations, experiences, and limited knowledge of menstrual complaints, instruments suitable for adults may not be suitable for adolescents.

Peony Pollen Protects against Primary Dysmenorrhea in Mice by Inhibiting Inflammatory Response and Regulating the COX2/PGE2 Pathway

Peony pollen contains multiple nutrients and components and has been used as a traditional Chinese medicine with a long history, but the effect of the treatment of primary dysmenorrhea remains to be clarified. The aim of this study is to investigate the therapeutic effect of peony pollen on primary dysmenorrhea mice and the potential mechanism. A uterus contraction model in vitro and primary dysmenorrhea mice were used to evaluate the treatment effect of peony pollen on primary dysmenorrhea. The primary dysmenorrhea mice were treated with 62.5 mg/kg, 125 mg/kg, or 250 mg/kg of peony pollen, and the writhing response, latency period, histopathological changes in the uterus, prostaglandin E2 (PGE2) and prostaglandin F2α (PGF2α) levels, and infiltration of neutrophils and macrophages were investigated. Protein expression of interleukin 1 β (IL-1β), interleukin 6 (IL-6), NOD-like receptor thermal protein domain associated protein 3 (NLRP3), cyclooxygenase-2 (COX-2), microsomal prostaglandin-E synthase 1 (mPGEs-1), BCL2-Associated X (Bax), B-cell lymphoma-2 (BCL-2), caspase-3, and cleaved caspase-3 were detected by Western blot, and the oxidative stress related marker malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and reactive oxygen species (ROS) were evaluated. Peony pollen could attenuate spontaneous or oxytocin-induced uterus contractions in vitro. Moreover, peony pollen decreased the writhing times, prolonged the writhing latency, and reduced the pathological damage of uterine tissues. Furthermore, the inflammatory cell infiltration and the protein expression of IL-1β, IL-6, and NLRP3 were decreased. The COX-2/PGE2 pathway was inhibited; oxidative stress and apoptosis in the uterus also improved in the uterus of primary dysmenorrhea mice. Peony pollen exerts a positive effect on primary dysmenorrhea by inhibiting the inflammatory response and modulating oxidative stress and apoptosis by regulating the COX-2/PGE2 pathway.

The Impact of Irregular Menstruation on Health: A Review of the Literature

Women are considered to have an irregular menstrual cycle if their cycle length is less than 21 days or more than 35 days, accompanied by less or very severe blood flow. The prevalence of menstrual cycle irregularities varies across countries. Irregular periods can occur due to changes in the body's levels of estrogen and progesterone hormones, which disrupt the normal pattern of the period. Menstrual irregularity has been found to be associated with various diseases and medical conditions, such as metabolic syndrome, coronary heart disease, type 2 diabetes mellitus, and rheumatoid arthritis. Anemia, osteoporosis, psychological problems, impaired quality of life, and infertility have also been recorded. Moreover, a significant correlation between irregular periods and the risk of developing pregnancy-related hypertensive disorders, as well as an increased risk of adverse obstetric and neonatal outcomes, has been proven. Therefore, irregular menstruation is considered an important health indicator among women. Physical, mental, social, psychological, and reproductive problems are often associated with menstrual irregularities. Thus, evaluating the factors associated with irregular menstruation is necessary to determine appropriate preventive and treatment strategies and to decrease the associated health problems. The aim of this review was to define normal and irregular menstruation, their types, and prevalence, to recognize the risk factors and causes of irregular menstruation, and to understand their impact on women's health.

Dysmenorrhea and psychological wellbeing among females with attention deficit hyperactivity disorder

Although rarely examined together, ADHD, emotional regulation (ER), and dysmenorrhea may be associated, which could create additive burdens on psychological well-being (PWB). Clinicians working with ADHD populations may need to take these challenges into consideration to maximize treatment outcomes. This study investigated the relationships among ADHD, dysmenorrhea, ER, and PWB within a sample of 266 adult females with a self-reported ADHD diagnosis. ADHD symptom severity was positively correlated with dysmenorrhea severity, but ER skills were not a significant moderator of this relationship. ADHD symptom severity was negatively correlated with PWB; however, this relationship was not moderated by dysmenorrhea severity nor ER ability. Overall, a positive association between ADHD symptom severity and dysmenorrhea severity was found in our sample. Further research is needed to understand the nature of this association, as well as factors that may contribute to PWB among individuals with these comorbid conditions.

Association between depression and dysmenorrhea among adolescent girls: multiple mediating effects of binge eating and sleep quality

BACKGROUND

Dysmenorrhea has a significant negative impact on teenagers' quality of life, and its prevalence is increasing annually. Although studies have explored the factors affecting dysmenorrhea, it remains unclear how these factors interact with one another. This study aimed to explore the mediating role of binge eating and sleep quality between depression and dysmenorrhea.

METHODS

This cross-sectional study recruited adolescent girls from the Health Status Survey of adolescents in Jinan, Shandong Province, and used multistage stratified cluster random sampling. Data was collected using an electronic questionnaire between March 9, 2022, and June 20, 2022. The Numerical Rating Scale and Cox Menstrual Symptom Scale were used to assess dysmenorrhea and the Patient Health Questionnaire-9 to assess depression. The mediation model was tested by Mplus 8.0, and the mediating effect was analyzed using the Product of Coefficients approach and the Bootstrap method.

RESULTS

Among the total of 7818 adolescent girls included in this study, the prevalence of dysmenorrhea is 60.5%. A significant positive association was found between dysmenorrhea and depression. Binge eating and sleep quality seemingly mediate this association. The mediating effect of sleep quality (21.31%) was greater than that of binge eating (6.18%).

CONCLUSIONS

The findings of this study point in the right direction for preventing and treating dysmenorrhea in adolescents. For adolescent dysmenorrhea, mental health should be considered and proactive steps taken for educating adolescents on healthy lifestyles to reduce negative consequences of dysmenorrhea. Longitudinal studies on the causal link and influence mechanisms between depression and dysmenorrhea should be conducted in the future.

The effect of vitamin D on the severity of dysmenorrhea and menstrual blood loss: a randomized clinical trial

BACKGROUND

Primary dysmenorrhea is considered as one of the women's main problems during reproductive age. The present study aimed to investigate the effect of vitamin D on the severity of dysmenorrhea and menstrual blood loss.

METHODS

This double-blind, randomized, placebo-controlled trial, was performed on 84 single female college students between 18 and 25 years old who living in dormitories. Students with primary dysmenorrhea and vitamin D deficiency were divided into experimental (n = 42) and control (n = 42) groups. Five days before the putative beginning of their next menstrual cycle, the experimental group received 300,000 IU vitamin D (50,000 IU, two tablets every 8 h), and the control group received a placebo (oral paraffin). The effects of the supplement on the severity of dysmenorrhea and menstrual blood loss were evaluated one cycle before and during two successive cycles. Using the visual analog scale (VAS), verbal multidimensional scoring system (VMS), and pictorial blood assessment chart (PBLAC) questionnaires. Fisher's exact, Chi-square, independent sample t-test and repeated measurements were used.

RESULTS

In total, 78 of the 84 students completed the study (39 students per group). The intervention resulted in a significant reduction in the mean scores of both the VAS and VMS in the experimental group, in the first and second menstrual cycles (p < 0.001, p < 0.001, respectively), but not in the means score of PBLAC. Mefenamic acid consumption at the first and second menstruation period, in the experimental group was lower than the control group (p = 0.009, p < 0.001, respectively).

CONCLUSIONS

The results indicate that vitamin D supplementation could decrease the severity of primary dysmenorrhea and the need to consume pain-relief medications. Contrariwise vitamin D supplementation had no significant effect on menstrual blood loss.

Medical and Behavioral Aspects of Adolescent Endometriosis: A Review of the Literature

The majority of young women will experience discomfort associated with menstrual cycles and miss out on education and social opportunities. Endometriosis, the presence of endometrial glands and stroma outside of uterus, is the most common cause of secondary dysmenorrhea and characterized by pain despite treatment with nonsteroidal anti-inflammatory drugs and hormonal agents. The true prevalence of adolescent endometriosis is not clear. Delay in diagnosis leads to persistent pain, affects quality of life, and potentially contributes to disease progression and subfertility. A laparoscopic diagnosis is the gold standard, but the surgical appearance may differ from adults, as endometriotic lesions are usually red or clear, making their identification a challenge for gynecologists who are unexperienced with endometriosis in adolescents. A personalized medical–surgical treatment is regarded as the most effective therapeutic strategy to achieve remission of symptoms, suppress disease progression, and protect future fertility. Studies have demonstrated how adolescent endometriosis negatively affects patients’ quality of life and psychosocial functioning. Development of therapeutic interventions targeting psychosocial function and quality of life is imperative for adolescent patients.

COVID-19-Associated Mental Health Impact on Menstrual Function Aspects: Dysmenorrhea and Premenstrual Syndrome, and Genitourinary Tract Health: A Cross Sectional Study among Jordanian Medical Students

The physiology of reproduction is affected by psychological distress through neuroendocrine pathways. Historically, COVID-19 is one of the most stressful events with devastating consequences. This research aims to investigate the relationship between dysmenorrhea, PMS, and reproductive tract health on one hand, and COVID-19-related anxiety, depression, and stress on the other among medical students in Jordan. Medical students were invited through teaching platforms and social media to complete an online survey. SPSS software was used to analyze data. A total of 385 medical students participated in this research. Hence, 49.9% of the study population reported severe dysmenorrhea during COVID-19 compared to 36.9% before COVID-19 (p = 0.000). Dysmenorrhea was significantly associated with disruptions of sport and daily activities during COVID-19 (p = 0.015 and p = 0.002, respectively). The prevalence of PMS components, e.g., mastalgia, fatigue, headache, palpitation, and emotional and sleep disturbances, was raised during COVID-19 compared with before (p < 0.05). Symptoms of genitourinary tract infections, such as lower abdominal pain, vaginal discharge, genitalia rash/ulcers and itching, and urgency, were significantly increased after COVID-19 (p < 0.05). Positive Pearson correlations between COVID-19-associated mental health disorders and dysmenorrhea severity, PMS, and genital tract health abnormalities were observed (p < 0.05). The multiple linear regression model revealed that dysmenorrhea severity, PMS symptoms like palpitation, and genitourinary symptoms like lower abdominal pain and urgency were associated with worsening of depression, while dysuria was associated with a protective effect against depression. Moreover, it was observed that dysmenorrhea severity, PMS symptoms, such as headache and palpitation, and urinary urgency were associated with aggravation of anxiety. However, food craving and dysuria were protective against anxiety. Finally, dysmenorrhea severity, PMS symptoms of headache and palpitation, lower abdominal pain, and urgency were related to worsening of stress, whereas the premenstrual symptom of breast pain was a protective factor against stress. This work showed that COVID-19 pandemic-related psychological distress and menstrual, premenstrual, and genitourinary symptoms are closely related. Further future work is required to evaluate the long lasting-effects of the pandemic on mental health and the physiology of reproduction.

Machine Learning Analysis Reveals Abnormal Static and Dynamic Low-Frequency Oscillations Indicative of Long-Term Menstrual Pain in Primary Dysmenorrhea Patients

BACKGROUND

Previous neuroimaging studies demonstrated that patients with primary dysmenorrhea (PD) exhibited dysfunctional resting-state brain activity. However, alterations of dynamic brain activity in PD patients have not been fully characterized.

PURPOSE

Our study aimed to assess the effect of long-term menstrual pain on changes in static and dynamic neural activity in PD patients.

MATERIAL AND METHODS

Twenty-eight PD patients and 28 healthy controls (HCs) underwent resting-state magnetic resonance imaging scans. The amplitude of low-frequency fluctuations (ALFF) and dynamic ALFF was used as classification features in a machine learning approach involving a support vector machine (SVM) classifier.

RESULTS

Compared with the HC group, PD patients showed significantly increased ALFF values in the right cerebellum_crus2, right rectus, left supplementary motor area, right superior frontal gyrus, right supplementary motor area, and left superior frontal medial gyrus. Additionally, PD patients showed significantly decreased ALFF values in the right middle temporal gyrus and left thalamus. PD patients also showed significantly increased dALFF values in the right fusiform, Vermis_10, right middle temporal gyrus, right putamen, right insula, left thalamus, right precentral gyrus, and right postcentral gyrus. Based on ALFF and dALFF values, the SVM classifier achieved respective overall accuracies of 96.36% and 85.45% and respective areas under the curve of 1.0 and 0.95.

CONCLUSION

PD patients demonstrated abnormal static and dynamic brain activities that involved the default mode network, sensorimotor network, and pain-related subcortical nuclei. Moreover, ALFF and dALFF may offer sensitive biomarkers for distinguishing patients with PD from HCs.

Significant Increase in Depression in Women With Primary Dysmenorrhea: A Systematic Review and Cumulative Analysis

Women with primary dysmenorrhea are vulnerable to develop a depressive disorder, which is a common form of psycho-disturbance. However, clinical findings are inconsistent across studies, and the evidence has not been previously synthesized. This study aims to investigate whether primary dysmenorrhea is associated with a higher risk of depression via a cumulative analysis. Four electronic databases were systematically searched for the eligible studies. The combined effect was assessed by analyzing the relative risk (RR) and standard mean differences (SMD) with a 95% confidence interval (CI). This cumulative analysis was registered on the PROSPERO (ID: CRD42020169601). Of 972 publications, a total of 10 studies involving 4,691 participants were included. Pooled results from six included studies showed that primary dysmenorrhea was associated with a significant depressive disorder (RR = 1.72, 95%CI: 1.44 to 2.0, P < 0.001; heterogeneity: I ² = 0%, P = 0.544). In addition, synthesis results from two studies provided the BDI scores suggested that dysmenorrhea had significantly higher scores when compared to non-dysmenorrhea (SMD = 0.47, 95% CI: 0.31-0.62, P < 0.001; heterogeneity: I ² = 0%, P = 0.518). However, in the two studies providing the PROMIS T-Score, the pooled result showed that there was no significant difference between women with dysmenorrhea and those without dysmenorrhea (P = 0.466). The overall quality of the evidence in our study was judged to MODERATE. The present study has confirmed the positive relationship between primary dysmenorrhea and depression. Social supports and medical help from pain management physicians or psychologists are important interventions for women with dysmenorrhea-suffering depressive disorder.
