Introduction Dysmenorrhea is a physical and mental burden for women, negatively affecting health-related quality of life (HRQL) and work productivity. However, data on HRQL and work productivity of Japanese women are scarce. Methods In this prospective observational study, 397 Japanese women received low-dose estrogen/progestin (LEP) or non-LEP treatment (non-steroidal anti-inflammatory drugs or Chinese herbal medicines) for primary/secondary dysmenorrhea and completed survey questionnaires online regarding menstrual symptoms, HRQL, and work productivity. Regression analysis was performed to compare the groups and evaluate outcomes over time using the paired t test. Subgroup analysis was performed using stratification by patient background, and correlations between improvement in menstrual symptoms/HRQL and work productivity were investigated using Spearman’s rank correlation coefficient. Results Significant reductions in the modified Menstrual Distress Questionnaire (mMDQ) total score were shown in the LEP group ( n = 251) ( P < 0.01), but not the non-LEP group ( n = 146). Significant improvements in HRQL, measured by the 36-Item Short-Form Health Survey v2.0 (SF-36v2.0), were shown in the LEP group, but not the non-LEP group. Improvements were seen in mental component summary and 7/8 domains (role physical, bodily pain, general health, role emotional, mental health, vitality, and social functioning) in the LEP group, but not the non-LEP group. There were no differences in the physical component summary and role functioning in either group. Improvements in work productivity, measured by the modified Work Productivity and Activity Impairment Questionnaire (mWPAI), were greater in the LEP group vs. non-LEP group. Regression analysis showed differences in improvements between the groups in the mMDQ total score, SF-36v2.0, and mWPAI. A correlation between mMDQ or HRQL and work productivity was seen. Conclusion In Japanese women, dysmenorrhea is associated with reduced HRQL and work productivity. In real-world clinical practice, improvements in physical and mental menstrual symptoms, HRQL, and work productivity were observed with LEP treatment.

Introduction Dysmenorrhea and endometriosis are common gynecologic disorders among women of reproductive age that significantly impact health-related quality of life (HRQL) as well as productivity. Although there are treatment options listed in Japanese guidelines, a gap remains in unmet medical needs for maximizing treatment outcome. The extended regimen of ethinylestradiol and drospirenone (EE/DRSP) (taken daily for up to 120 consecutive days) has been available in Japan for treating dysmenorrhea and/or endometriosis-associated pain since 2016. Yet, the effectiveness of its usage on HRQL has not been investigated elsewhere to date. Therefore, in this study, we aim to observe changes in HRQL of Japanese women treated with an extended regimen of EE/DRSP for dysmenorrhea and/or endometriosis-associated pain. Methods As part of a 2-year post-marketing surveillance study, women with dysmenorrhea or endometriosis-associated pelvic pain were prescribed extended EE/DRSP during routine clinical practice. Data were collected 1 month before and 3 and 6 months after initiating treatment. Primary outcomes were the Menstrual Distress Questionnaire (MDQ) (before, during, and after menstruation) in patients with dysmenorrhea, and the Endometriosis Impact Scale (EIS) and European Quality of Life 5-dimensions 5-level instrument (EQ-5D-5L) in patients with endometriosis. Results The study cohort included 315 patients (mean age 28.9 years) with dysmenorrhea and 262 patients (mean age 31.3 years) with endometriosis. Mean MDQ total scores before and during menstruation decreased significantly after 6 months with extended EE/DRSP; there was no improvement in after-menstruation MDQ score. Mean EIS domain scores improved significantly by 6 months, with improvement in most EIS individual item scores. Mean EQ-5D-5L scores increased slightly during 6 months of treatment. Conclusions Extended EE/DRSP treatment improved HRQL outcomes in Japanese women with dysmenorrhea or endometriosis-associated pelvic pain.

Introduction The present study collected 1-year follow-up patient-reported outcome data from Japanese women with dysmenorrhea and/or heavy menstrual bleeding (HMB) who underwent insertion of the levonorgestrel-releasing intrauterine system (LNG-IUS) 52 mg. We aimed to evaluate the quality of life (QOL) of Japanese women over the course of the investigational period. Methods This was a multicenter, non-interventional, prospective, single-cohort, post-marketing surveillance study (J-MIRAI). The primary outcome was the median change in the Menstrual Distress Questionnaire (MDQ) and Menorrhagia Multi-Attribute Scale (MMAS) scores from baseline to 3 and 12 months after LNG-IUS insertion, with decreasing and increasing scores, respectively, indicating improvement. The secondary outcomes were the statistical relationships between the MDQ and menstrual pain (measured by a visual analog scale, VAS), and between the MMAS and pictorial blood loss assessment chart (PBAC) scores by regression analysis. Results In total, 593 patients were evaluated; 376, 467, and 250 patients were diagnosed with dysmenorrhea, HMB, or both, respectively. The median MDQ score decreased significantly at 3 and 12 months after LNG-IUS insertion in both the premenstrual and menstrual periods (both p < 0.001 vs baseline), and the median MMAS score showed a similar improvement during the menstrual period. Changes in median MDQ and MMAS scores were observed regardless of patient background. Correlations between MDQ and menstrual pain (VAS) and between MMAS and PBAC scores were found (estimated regression coefficients 0.29 and − 0.15, respectively). Conclusion The LNG-IUS contributed to improvements in the QOL of patients with dysmenorrhea, HMB, and both, regardless of patient background characteristics.
