Background: An international collaborative study was conducted to determine the demographic and clinical profiles of Hispanic/Latinx endometriosis patients from Latin America and Spain using the Minimal Clinical Questionnaire developed by the World Endometriosis Research Foundation (WERF) Endometriosis Phenome and Biobanking Harmonization Project (EPHect).Methods: This is a cross-sectional study to collect self-reported data on demographics, lifestyle, and endometriosis symptoms of Hispanic/Latinx endometriosis patients from April 2019 to February 2020. The EPHect Minimal Clinical Questionnaire (EPQ-M) was translated into Spanish. Comprehension and length of the translated survey were assessed by Spanish-speaking women. An electronic link was distributed via social media of endometriosis patient associations from 11 Latin American countries and Spain. Descriptive statistics (frequency, means and SD, percentages, and proportions) and correlations were conducted using SPSSv26.Results: The questionnaire was completed by 1,378 participants from 23 countries; 94.6% had self-reported diagnosis of endometriosis. Diagnostic delay was 6.6 years. Most participants had higher education, private health insurance, and were employed. The most common symptoms were back/leg pain (85.4%) and fatigue (80.7%). The mean number of children was 1.5; 34.4% had miscarriages; the mean length of infertility was 3.7 years; 47.2% reported pregnancy complications. The most common hormone treatment was oral contraceptives (47.0%). The most common comorbidities were migraines (24.1%), polycystic ovary syndrome (PCOS) (22.2%), and irritable bowel syndrome (21.1%). Most participants (97.0%) experienced pelvic pain during menses; for 78.7%, pain was severe; 86.4% reported dyspareunia. The mean age of dysmenorrhea onset was 16.2 years (SD ± 6.1). Hormone treatments were underutilized, while impact was substantial. Pain catastrophizing scores were significantly correlated with pain intensity (p < 0.001).Conclusion: This is the first comprehensive effort to generate a clinical–demographic profile of Hispanic/Latinx endometriosis patients. Differences in clinical presentation compared to other cohorts included higher prevalence and severity of dysmenorrhea and dyspareunia and high levels of pain catastrophizing. Though future studies are needed to dissect the impact of race and ethnicity on pain and impact, this profile is the first step to facilitate the recognition of risk factors and diagnostic features and promote improved clinical management of this patient population. The EPHect questionnaire is an efficient tool to capture data to allow comparisons across ethnicities and geographic regions and tackle disparities in endometriosis research.

Endometriosis is a complex disease affecting approximately 5–10% individuals worldwide. Prevalence rates in Latin-America and the Caribbean are largely unknown, with published data only from Puerto Rico and Chile. Pain associated with endometriosis negatively affects patients’ health and quality of life. However, there is a need to better understand the role played by psychosocial variables such as stigma and social support in diverse cultural contexts. The purpose of this study was to examine the mediating role of endometriosis related stigma (endo-stigma) and the moderating role of social support on the endometriosis QoL and self-esteem among women with endometriosis from Latin America and the Caribbean. A cross-sectional design with online survey techniques was implemented. A total of 169 self-identified cisgender women with endometriosis from 14 Latin-American and Caribbean countries participated in the study. We used partial least squares structural equation modeling (PLS-SEM) to examine the study’s hypotheses. Incapacitating pain was positively and significantly related to endometriosis QoL as measured by the EHP-5 (b = .266, p < .01). Endo-stigma was positively and significantly related to endometriosis QoL (b = .340, p< .01) and self-esteem (b = .297, p< .01). In addition, endo-stigma mediated the relationship between incapacitating pain and self-esteem (IE = .073, p = .018). Finally, social support moderated the relationship between stigma stress and endometriosis QoL (b = .060, p = .039). Findings suggest stigma could be one of the mechanisms through which the relationship between incapacitating pain and self-esteem among Latin American and Caribbean women with endometriosis could be partially explained. Furthermore, women who scored high in the need for social support and stigma stress also showed worst endometriosis QoL. These results point towards the need to develop tailored interventions targeting these factors in order to foster a better QoL and wellbeing for this population in the context of Latin America and the Caribbean.
