This study analyzed endometriosis symptom prevalence across Danish regions and found little variation, but identified associations between higher symptom prevalence and younger age, lower socioeconomic status, non-Danish origin, and lower education.

Abstract

INTRODUCTION: Endometriosis is characterized by a range of non-specific symptoms which may contribute to the significant delay in diagnosis. Knowledge about the distribution of endometriosis symptoms across different geographical regions as well as other sociodemographic factors could add knowledge and guide initiatives to reduce this underdiagnosis. This study aims to explore how the prevalence of endometriosis symptoms and indicators are linked to the different sociodemographic factors. STUDY DESIGN: The study used data from the CYKLUS-survey; a women's health survey sent to 63,199 Danish women aged 16 to 51 in 2023. Self-reported information on endometriosis symptoms and indicators was linked to Danish register data on sociodemographic factors. Age-standardized prevalence of six endometriosis symptoms and indicators were estimated for each of the nine different regions of residence and for the whole country. In addition, logistic regression analysis was used to estimate the association between sociodemographic factors and the six endometriosis symptoms and indicators. RESULTS: 11,407 women were included in the study. Age-standardized prevalence of symptoms showed little variation across Danish regions. However, younger age, lower socioeconomic status, and non-Danish origin were found to be associated with higher prevalences, and higher education was found to be associated with lower prevalences. CONCLUSION: No major regional differences in endometriosis symptoms and indicators were found. However, associations were found between several sociodemographic factors and endometriosis symptoms and indicators, suggesting disparities in the burden of symptoms. These findings call for further investigation into factors causing these disparities in Denmark.
