Abstract
This study aimed to investigate the prevalence of Lichen Sclerosus et Atrophicus among women aged 65 and older, utilizing data from the All of Us Database, a comprehensive initiative by the United States National Institutes of Health. The AUD, which includes de-identified patient data, was queried for female patients diagnosed with LS&A, identified by the ICD-10-CM code L90.0. Our analysis encompassed 248,130 female patients, out of which 1,087 were diagnosed with LS&A, resulting in a prevalence rate of 0.438% (95% CI: 0.412-0.464). The study revealed that the prevalence of LS&A increases with age, peaking in the 81-85 year age group, with a prevalence of 1.298% (95% CI: 1.030-1.565), although not significantly different from adjacent age groups. Racial analysis showed the highest prevalence among White patients, with a prevalence of 0.622% (95% CI: 0.581-0.663). Despite the low overall prevalence, the study suggests potential underestimation due to reliance on ICD-10 billing codes and demographic discrepancies between the AUD population and the general US population. The findings underscore the need for improved screening guidelines for genital dermatologic conditions in elderly women and enhanced training for healthcare professionals in dermatology and obstetrics and gynecology. This study highlights the importance of comprehensive databases in understanding the epidemiology of less common diseases and the need for further research to accurately estimate the prevalence of LS&A in the general population.
