Introduction: Electroacupuncture (EA) has been applied in dysmenorrhea and has shown good efficacy. The mechanisms of EA are associated with autonomic nervous system adjustments and neuroendocrine regulation. Laser acupuncture (LA), however, has been widely investigated for its noninvasiveness. However, it remains uncertain whether LA is as effective as EA. This study aimed to compare EA and LA head to head in dysmenorrhea. Methods: A crossover, randomized clinical trial was conducted. EA or LA was applied to selected acupuncture points. Participants were randomized into two sequence treatment groups who received either EA or LA twice per week in luteal phase for 3 months followed by 2-month washout, then shifted to other groups (sequence 1: EA > LA; sequence 2: LA > EA). Outcome measures were heart rate variability (HRV), prostaglandins (PGs), pain, and quality-of-life (QoL) assessment (QoL-SF12). We also compared the effect of EA and LA in low and high LF/HF (low frequency/high frequency) status. Results: Totally, 43 participants completed all treatments. Both EA and LA significantly improved HRV activity and were effective in reducing pain (Visual Analog Scale [VAS]; EA: p  < 0.001 and LA: p  = 0.010) and improving QoL (SF12: EA: p  < 0.001, LA, p  = 0.017); although without intergroup difference. EA reduced PGs significantly ( p  < 0.001; δ p  = 0.068). In low LF/HF, EA had stronger effects than LA in increasing parasympathetic tone in respect of percentage of successive RR intervals that differ by more than 50 ms (pNN50; p  = 0.053) and very low-frequency band (VLF; p  = 0.035). Conclusion: There is no significant difference between EA and LA in improving autonomic nervous system dysfunction, pain, and QoL in dysmenorrhea. EA is prominent in PGs changing and preserving vagus tone in low LF/HF; yet LA is noninvasive for those who have needle phobia. Whether LA is equivalent with EA and the mechanism warrants further study. Clinical trial identification number: NCT04178226.

Aim: Different nonpharmacological strategies are adopted to decrease primary dysmenorrhea (PD)-related pain. The present study aimed to verify women's use of nonpharmacological methods for pain and compare them with evidence from the literature. Materials & methods: A two-step study was conducted, comprising an online survey with 9144 women to assess nonpharmacological strategies for relieving PD-related pain, and a literature review on PubMed of verify the evidence of nonpharmacological methods. Results: Many women reported using heat therapy (61.5%), tea (42.4%) and massage (30.9%) to alleviate menstrual pain. However, the literature on these methods is limited. Conclusion: Several nonpharmacological methods are used by women to relieve PD-related pain and studies with low bias risk are needed to prove their effectiveness.

Pain empathy, defined as the ability of one person to understand another person's pain, shows large individual variations. The anterior insula is the core region of the pain empathy network. However, the relationship between white matter (WM) properties of the fiber tracts connecting the anterior insula with other cortical regions and an individual's ability to modulate pain empathy remains largely unclear. In this study, we outline an automatic seed-based fiber streamline (sFS) analysis method and multivariate pattern analysis (MVPA) to predict the levels of pain empathy in healthy women and women with primary dysmenorrhoea (PDM). Using the sFS method, the anterior insula-based fiber tract network was divided into five fiber cluster groups. In healthy women, interindividual differences in pain empathy were predicted only by the WM properties of the five fiber cluster groups, suggesting that interindividual differences in pain empathy may rely on the connectivity of the anterior insula-based fiber tract network. In women with PDM, pain empathy could be predicted by a single cluster group. The mean WM properties along the anterior insular-rostroventral area of the inferior parietal lobule further mediated the effect of pain on empathy in patients with PDM. Our results suggest that chronic periodic pain may lead to maladaptive plastic changes, which could further impair empathy by making women with PDM feel more pain when they see other people experiencing pain. Our study also addresses an important gap in the analysis of the microstructural characteristics of seed-based fiber tract network., Competing Interests: Declaration of competing interest The authors have no conflict of interest to declare., (Copyright © 2024 The Author(s).

Background: The use of plant medications in Unani medicine has been suggested to alleviate pain and related symptoms associated with primary dysmenorrhea, thus enhancing the overall quality of life. The purpose of the current study was to evaluate and compare the efficacy of Zarawand Mudaharaj (Aristolochia rotunda L.) and Qust (Saussurea lappa C.B. Clarke) in treating primary dysmenorrhea., Methods: This single-blind, randomized comparative study was conducted on patients with primary dysmenorrhea aged 18-35 years. The study participants were randomly allocated into Group A and Group B. Group A received Zarawand Mudaharaj 2 g twice daily with 5 mL honey while Group B received Qust 1.5 g twice daily with 5 mL honey from the 1st to the 5th day of their menstrual cycles for three consecutive cycles. The primary outcome measures were changes in pain severity measured on a 10 cm Visual Analog Scale (VAS) and changes in Verbal Multidimensional Scoring System (VMSS) grades. The secondary outcome measures included changes in Health-Related Quality of Life (HRQoL) measured on short form health survey-12 (SF-12) and changes in the symptoms such as pain during menstruation, low-backache, nausea, vomiting, diarrhoea, giddiness, and headache., Results: Both groups showed a significant improvement in VMSS grade at all follow-ups compared to baseline (P < .0001). Group B showed better performance than Group A in changing the VMSS grade at the third cycle (P = .02) and the final follow-up (P = .002). Group B also had a more significant reduction in mean ± SD VAS score from baseline (6.43 ± 1.57) to the final follow-up (2.67 ± 1.69) (P < .0001) compared to Group A., Conclusion: The preliminary findings of the study support the use of Zarawand Mudaharaj and Qust in the treatment of primary dysmenorrhea, which is consistent with the traditional knowledge of Unani scholars.

Objective: This study aims to investigate the effect of physical activity, body mass index (BMI), and levels of prostaglandins (PGF2α) urine on the occurrence of dysmenorrhea in adolescents., Methods: A total of 128 female students included in the study. The study was conducted from January to March 2023 using a cross-sectional design. This study utilized the Menstrual Symptom Questionnaire (MSQ) and gynecological examination with ultrasonography. The urinary prostaglandin (PGF2α) was measured using the enzyme linked immuno sorbent assay (ELISA). Data were analyzed using the chi-square test and logistic regression test., Results: The age range of the participants included in the study was 14-17, with a mean age of 15.85 ± 0.65. There was an correlation between physical activity, BMI, and urinary prostaglandin (PGF2α) levels with the incidence of dysmenorrhea in adolescents (p < 0.001). In multivariate analysis, it revealed that underweight, and had a high urinary prostaglandin significant correlated to primary dysmenorrhea with odds ratio 4.78 (95% confidence interval [CI] 1.98-11.54) and 4.88 (95% CI 1.98-12.08), respectively. High physical activity and overweight was not associated with incidence of dysmenorrhea in adolescents., Conclusion: This study provides valuable insights into the correlation between physical activity, BMI, and levels of prostaglandins (PGF2α) in urine. A high level of urinary prostaglandin was found to be the most influential factor in the incidence of primary dysmenorrhea in adolescents. By addressing factors associated with dysmenorrhea in adolescents, healthcare professionals can potentially enhance well-being by reducing menstrual pain and encouraging a healthy lifestyle to prevent dysmenorrhea., (© 2024 Japan Society of Obstetrics and Gynecology.)

Objectives: To investigate the effect of electroacupuncture (EA) on Rho/Rho-associated coiled-coil-forming kinases (ROCK) signaling pathway of uterus tissue in rats with dysmenorrhea, so as to explore the underlying mechanism of EA treating primary dysmenorrhea (PD) and uterine smooth muscle spasm, and to observe whether there is a difference in the effect of meridian acupoints in Conception Vessel (CV) and Governer Vessel (GV)., Methods: Sixty female SD rats were randomly divided into saline, model, CV, GV, and non-acupoint groups, with 12 rats in each group. The dysmenorrhea model was established by subcutaneous injection of estradiol diphenhydrate combined with intraperitoneal injection of oxytocin (OT). EA (2 Hz) was applied to "Qihai" (CV6) and "Zhongji" (CV3) for CV group, "Mingmen" (GV4) and "Yaoshu" (GV2) for GV group, "non-acupoint 1" and "non-acupoint 3" on the left side for non-acupoint group, and manual acupuncture was applied to "Guanyuan" (CV4) for CV group, "Yaoyangguan" (GV3) for GV group, "non-acupoint 2" on the left side for non-acupoint group. The treatment was conducted for 20 min each time, once daily for 10 days. The writhing score was evaluated. The smooth myoelectric signals of rats' uterus in vivo were recorded by multi-channel physiological recorder. The uterine histopathological changes were observed by HE staining. The contents of prostaglandin F2α (PGF 2α ), OT and calcium ion (Ca 2+ ) in uterine tissue of rats were detected by ELISA. The protein and mRNA expression levels of smooth muscle 22-α (SM22-α), RhoA and ROCKⅡ in uterine tissue were detected by Western blot and fluorescence quantitative PCR, respectively., Results: Compared with the saline group, the writhing score of rats in the model group was increased ( P <0.01), the amplitude voltage of uterine smooth muscle in vivo was elevated ( P <0.01), the contents of PGF 2α , OT and Ca 2+ , the protein and mRNA expression of SM22-α, RhoA and ROCK Ⅱ in uterine tissue were all increased ( P <0.01). Compared with the model and the non-acupoint groups, the writhing scores of the CV and the GV groups were decreased ( P <0.01, P <0.05), the amplitude voltage of uterine smooth muscle was decreased ( P <0.01), the contents of PGF 2α , OT and Ca 2+ in uterine tissue were decreased ( P <0.01, P <0.05), and the protein expression and mRNA expression of SM22-α, RhoA and ROCKⅡ in uterine tissue were decreased ( P <0.01, P <0.05). HE staining showed extensive exfoliation of uterine intima with severe edema and increased glandular secretion in the model group, which was alleviated in the CV and GV groups., Conclusions: EA at acupoints of CV and GV can significantly reduce the writhing score, uterine smooth muscle amplitude voltage, pathological injury degree of uterus, and relieve spasm of uterine smooth muscle in dysmenorrhea rats, which may be related to its effect in regulating PGF 2α and OT contents, inhibiting the Rho/ROCK signaling pathway, and reducing the SM22-α, RhoA, ROCKⅡ protein and mRNA expression, and Ca 2+ content in uterine tissue.

Background: Dysmenorrhea, characterized by painful menstrual cramps, significantly impacts the well-being of women globally. Despite its prevalence and adverse effects, dysmenorrhea is often underdiagnosed and inadequately treated. This study aims to validate the Arabic version of the Working ability, Location, Intensity, Days of pain, and Dysmenorrhea (WaLIDD) scale among Lebanese female university students aged 18– 45. Methods: This cross-sectional study, involving 729 participants, utilized a translated WaLIDD scale and the Depression, Anxiety, and Stress Scales (DASS-8). Results: Confirmatory Factor Analysis (CFA) confirmed the one-factor structure of the WaLIDD scale, demonstrating excellent fit indices, with good internal reliability. Concurrent validity analysis revealed significant associations between higher WaLIDD scores and elevated levels of depression, anxiety, and stress. The prevalence of dysmenorrhea in the study was estimated at 7.3%. Conclusion: The study underscores the importance of the WaLIDD scale as a reliable and valid tool for assessing dysmenorrhea among Arabic-speaking populations. The successful validation of the Arabic version facilitates its application in Lebanon and potentially other Arab regions, providing a universal tool to predict and assess dysmenorrhea and its impact. Further research is encouraged to explore the scale's applicability in clinical settings and tailor interventions for improved women's well-being. [ABSTRACT FROM AUTHOR]

Abstract Primary dysmenorrhea (PD), a prevalent menstrual condition characterized by pelvic pain during the menstrual cycle, significantly impacts the quality of life of women and produces increased pain sensitivity that can persist throughout the menstrual cycle. However, scientific literature has not studied whether there are implications for alterations in muscle function and endurance in the abdominopelvic region during the non-painful phases of the menstrual cycle. The aim of this study was to compare muscle function and endurance capacity in the abdominopelvic region in women with PD versus women without this condition. An observational, cross-sectional study was designed to analyze muscle activation and endurance capacity using electromyography (EMG) during McGill exercises. Forty-four women were included, 22 with PD and 22 without dysmenorrhea. The results did not indicate significant differences in muscle activation and endurance of the abdominopelvic musculature between the two groups (p > 0.05). However, the analysis suggests that women with primary dysmenorrhea might develop compensatory strategies that allow them to maintain physical function despite their condition. These results suggest that the approach to PD could focus more on pain management rather than physical functionality, and more studies are needed from a comprehensive approach to more accurately evaluate the relationship between PD and muscle function.

Abstract Background Menstrual pain, or dysmenorrhea, can cause physical discomfort and mood swings, potentially impacting the attitudes of female nursing students toward marriage. Effective emotion regulation strategies are essential for managing stress and shaping their perspectives on marriage. This study sought to investigate the relationship between dysmenorrhea, emotional regulation skills, and attitudes toward marriage among female nursing students. Methods A cross-sectional survey was conducted using a stratified sample of 504 female nursing students from four academic years. The study used a combination of the Working Ability, Location, Intensity, Days of Pain, Dysmenorrhea (WaLIDD) Questionnaire, the Marital Attitude Scale, and the Emotion Regulation Questionnaire to assess various factors among the participants. The Pearson correlation coefficient was utilized to examine the relationships among the three primary variables. Additionally, linear regression analysis was employed to forecast attitudes toward marriage based on factors such as dysmenorrhea, residence, family type, regularity of the menstrual cycle, and age at menarche. Results The findings of the study are significant, revealing a negative correlation between dysmenorrhea and marital attitudes (r = -0.105, p = 0.019). Dysmenorrhea exhibited minimal and non-significant correlations with emotion regulation strategies, including cognitive reappraisal (r = -0.006, p = 0.898) and expressive suppression (r = 0.013, p = 0.774). In contrast, marital attitudes significantly influenced emotion regulation (β = -0.169, p

Objective: The objective of this study is to determine the prevalence of dysmenorrhea and to assess the predictors of pain intensity during dysmenorrhea among female medical students at Rawalpindi Medical University. Study Design: Descriptive Cross-sectional study Place and Duration of Study: The study was conducted from May 2023 to October 2023 at Rawalpindi Medical University. Materials and Methods: A validated, self-structured and self-administered 24 items questionnaire regarding dysmenorrhea was used to assess the prevalence and pain intensity of dysmenorrhea focused on 277 undergraduate medical students, excluding those with any pre-existing pelvic pathology. Participants were selected through convenience sampling and data was analyzed using SPSS version 26. Results: The study involved 277 female medical students, showing an 83.2% dysmenorrhea prevalence. Based on visual analog scale, most of the research participants experienced moderate to severe pain (49.6%), along with symptoms like depressed mood (50.7%) and mood swings (51.4%). Common outcomes were limited daily activities (57.5%) and emotional instability (55%). Heavy bleeding (p=0.041, OR=3.56) and stress (p=0.041, OR=2.108) were significant predictors. BMI and caffeine consumption showed no significant improvement, but the pain's duration during periods significantly affected pain scale scores, with the "more than 3 days" group reporting the most severe pain. Conclusion: Dysmenorrhea is widespread among female medical students, causing substantial disruptions in their daily routines. This condition is closely linked to heavy bleeding and stress, highlighting the importance of addressing these factors. Understanding the timing and duration of pain during the menstrual cycle is crucial for developing effective treatment strategies.

Objectives: Dysmenorrhea is a known phenomenon and not just recently, and investigations conducted recently have shown that female adolescents are very susceptible to this condition. Our goal is to determine the prevalence of dysmenorrhea in Tunisia, its risk factors, its impact on truancy rates, and the therapeutic attitudes of girls attending high school about this illness using an epidemiological survey., Methods: This eight-month study, which spans from October 2022 to May 2023, focuses on 160 high school girls between the ages of 13 and 21. It is a transversal descriptive study. The required data is gathered through the distribution of a self-administered questionnaire., Results: The mean age of female adolescent participants is 16.44 years and 68 % of them reported dysmenorrhea. The most common symptoms of the pain were headaches (40.0 %). There is a notable prevalence of absenteeism during the menstrual cycle. There seems to be a trend toward self-medication., Conclusions: In Tunisia, primary dysmenorrhea is a common cause of school absenteeism among female adolescents. Girls' attitudes toward dysmenorrhea indicate a lack of knowledge, which is why it is crucial for midwives and physicians to educate teenage girls about the condition., (© 2024 Walter de Gruyter GmbH, Berlin/Boston.)

Abstract Background Exercise is increasingly being promoted as an effective treatment for primary dysmenorrhea (PD). This study aims to conduct a comprehensive network meta-analysis (NMA) of randomized controlled trials to identify the optimal types and dosages of exercise for managing PD in women. Methods Adhering to PRISMA-NMA guidelines, we systematically reviewed RCTs from the Cochrane Library, Web of Science, PubMed, and Embase databases up to May 23, 2024. Data analysis was performed using ‘GEMTC’ and ‘BUGSnet’ packages within a Bayesian framework in R and a hierarchy of exercise treatments was also calculated using surface under the cumulative ranking curve (SUCRA) values. Subgroup analyses were conducted to identify the most effective exercise regimens, including duration, frequency, and volume of the exercise interventions. Results Forty-nine studies representing 3,129 participants (1,640 exercises and 1,489 controls) were included. The results showed that all exercise interventions significantly reduced menstrual pain of the PD patients. Of six exercise intervention modalities based on the study ranked effectiveness, statistically significant reductions in pain intensity were found for resistance exercise and multi-component exercise. Multi-component exercise and stretching exercise were ranked best for menstrual symptoms, while core-strengthening exercise and multi-component exercise had the greatest impact on reducing pain duration. Significant and clinically important reductions or reliefs in pain occurred with 4 to 8 weeks of exercise training from all exercises, with resistance exercise showing the best efficacy when the duration exceeded 8 weeks, followed by multi-component exercise and mind-body exercise. Multi-component exercise and aerobic exercise with 1 to 3 sessions per week induced greater benefit in performance improvements, while resistance exercise with increased frequency showed the enhanced performance. Resistance exercise could elicit better efficacy within` 30-minute training duration, and multi-component exercise was ranked the best if such a training over 30 min. Conclusion This study provided quantitative insight into efficacy and effectiveness of exercise interventions on PD treatments. All six different exercises are associated with positive influence on PD management. Our study indicates that this exercise training induced adaptation may have therapeutic benefits for PD patients; however, such alterations and improvements are affected by exercise regiments.

Abstract 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 Bartın 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

Abstract Primary dysmenorrhea (PD) is a common global health concern. However, limited studies explored the association between soft drinks intake and PD among female undergraduates in China. To determine the association between soft drinks (carbonated soft drinks, etc.) as well coffee intake and the incidence/severity of PD among female undergraduates in China. We performed a cross-sectional study among 1809 female undergraduates in China from September 29, 2020 to October 22, 2020. The demographic information and menstrual information of the participants were collected by a self-administrated questionnaire. Chi-square test, ANOVA test, and logistic regression test were used to investigate the association between soft drinks intake and the incidence/severity of PD. We also conducted stratification analysis among different locations (rural or urban). The prevalence of PD was 47.1% (n = 852). There were 221 (25.9%) participants suffered from severe pain. In the participants with PD, the OR of carbonated soft drinks intake was 1.244 (95% CI 1.010–1.533). Among the participants with PD from rural areas, the OR of carbonated soft drinks intake was 1.402 (95% CI 1.045–1.881), compared with the non-carbonated soft drink group. In the participants with moderate and severe PD, the OR of coffee intake was 0.451 (95% CI 0.228–0.892), compared with the non-coffee-drinking group. There was a significant association between carbonated soft drinks intake frequency and the severity of PD (P

Graphene-based warm uterus acupoint paste (GWUAP) is an emerging non-drug alternative therapy for the treatment of primary dysmenorrhea (PD), but the underlying mechanism is still unclear. SD female rats were randomly divided into control group, model group and treatment group to explore the mechanism of GWUAP in the treatment of PD. Combined with 16S rDNA and fecal metabolomics, the diversity of microbiota and metabolites in each group was comprehensively evaluated. In this study, GWUAP reduced the torsion score of PD model rats, improved the pathological morphology of uterine tissue, reduced the pathological damage score of uterine tissue, and reversed the expression levels of inflammatory factors, pain factors and sex hormones. The 16 S rDNA sequencing of fecal samples showed that the abundance of Lactobacillus in the intestinal flora of the model group decreased and the abundance of Romboutsia increased, while the abundance of Lactobacillus in the intestinal flora of the treatment group increased and the abundance of Romboutsia decreased, which improved the imbalance of flora diversity in PD rats. In addition, 32 metabolites related to therapeutic effects were identified by metabolomics of fecal samples. Moreover, there is a close correlation between fecal microbiota and metabolites. Therefore, the mechanism of GWUAP in the treatment of PD remains to be further studied., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Wang, Li, Cao, Zhao, Xu, Chai, Zhang, Liu and Wang.)

Introduction: Dysmenorrhea is the most common cause of gynecological pain among women that has considerable impact on quality of life and psychosocial wellbeing. Non-steroidal anti-inflammatory drugs (NSAIDs) and hormonal therapies are most commonly used to treat dysmenorrhea. However, given these drugs are often associated with bothersome side effects and are less effective when there is an underlying cause contributing to dysmenorrhea (e.g. endometriosis), a patient-centered approach to managing dysmenorrhea is important. Various new drugs are currently being investigated for the treatment of primary and secondary dysmenorrhea., Areas Covered: This review provides an updated overview on new therapeutic targets and investigational drugs for the treatment of primary and secondary dysmenorrhea. The authors describe the clinical development and implications of these drugs., Expert Opinion: Among the investigative drugs discussed in this review, anti-inflammatories show the most promising results for the treatment of dysmenorrhea. However, given some trials have considerable methodological limitations, many drugs cannot be currently recommended. Research focused on understanding the mechanisms involved in menstruation and its associated symptoms will be important to identify new therapeutic targets for dysmenorrhea. Further robust clinical trials are required to better understand the efficacy and safety of investigational drugs for treating primary and secondary dysmenorrhea.

The initial physiological change in adolescent girls is the onset of menstruation. The most prevalent challenge they face regarding menstruation is primary dysmenorrhea, characterized by persistent or intermittent pelvic pain in the lower abdomen. The aim of this study was to investigate the influences of stress levels and physical activities on primary dysmenorrhea. A cross-sectional was conducted in Cirebon, Indonesia, in 2023 included young women who had never given birth (nullipara), aged 17-25 years old, had menstruated, and had no history of smoking and alcohol. The data were collected using a set of questionnaires consisting of the Numeric Rating Scale (NRS) to determine primary dysmenorrhea pain, the Depression Anxiety Stress Scales 42 (DASS 42) to determine the level of stress and the International Physical Activity Questionnaire (IPAQ) to determine physical activity. Pearson's correlation test was used to assess the correlation between the variables (stress levels, physical activity, and dysmenorrhea). A total of 150 young women were included in the study. Moderate stress levels (23.3%) and high physical activity (90.7%) were the most prevalent category observed among studied participants. Approximately 42% of them experienced mild dysmenorrhea pain. Our analysis indicated that stress levels and physical activities had strong positive and negative correlations with dysmenorrhea pain levels, with r =0.782 and r =-0.748, respectively, with both had p <0.001. This highlights that controlling stress could be beneficial in preventing dysmenorrhea pain among young women., Competing Interests: All the authors declare that there are no conflicts of interest., (© 2024 by the authors.)
