Health Disparities in Vasomotor Symptom Prevalence and Treatment Discontinuation in Women of Menopausal Age: A Commercial Claims Analysis.

Objective: To estimate the prevalence of diagnosed vasomotor symptoms (VMS) due to menopause among US women aged 40-64 years and assess sociodemographic differences in VMS prevalence and risk of discontinuing VMS-related treatment. Materials and Methods: This retrospective study evaluated merged data from IQVIA's PharMetrics Plus medical claims and consumer attributes databases for 2017-2020. VMS diagnosis was identified using International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) diagnosis codes. Continuous enrollment was required ≥6 months before and 12 months after diagnosis date. Treatment discontinuation was measured for VMS-related treatments initiated at diagnosis or during the 12 months after diagnosis. Treatment duration was measured from diagnosis to the first day of a ≥90-day treatment gap. A Cox proportional hazards model was used to determine factors associated with risk of treatment discontinuation. Results: Among 7,386,206 eligible women, the 4-year prevalence of diagnosed VMS in 2017-2020 was 79.1 per 1,000 and was highest among non-Hispanic White women (82.5 per 1,000), followed by Hispanic (77.3), Black (71.6), and Asian women (64.5). Rates were higher among women living in urban areas and those with higher education and income. Among women newly diagnosed with VMS (n = 226,262), median treatment duration was 297 days. Black, Asian, and Hispanic women had higher risks of discontinuing treatment than non-Hispanic White women. Lower income was also associated with higher risk of discontinuation than higher income. Conclusion: Lower prevalence of diagnosed VMS and higher risk of treatment discontinuation were observed among racial/ethnic minorities and women with less education and income, suggesting possible underdiagnosis and unmet needs.
