Demographic Statistics on Uterine Fibroids

Goals

To find demographic statistics on Uterine Fibroids in the US broken out by race/ethnicity, age, geographical locations, and household income. Provide a breakdown of this information with percentages of incidence and the number of people affected.

Early Findings

  • According to Mayo Clinic, "black women are more likely to have fibroids than are women of other racial groups." Mayo Clinic does not provide a breakdown of demographic statistics on uterine fibroids in the US.

American Journal of Obstetrics and Gynecology

  • A study published in the American Journal of Obstetrics and Gynecology in October 2018 provides a detailed breakdown of the fibroid diagnosis incidence, 10-year secular trends (2005 through 2014), and prevalence in the US.
  • According to this study, women with fibroid diagnoses were more likely to be non-white (28.8%) than women without fibroid diagnoses (24.7%).
  • Incidence rates were "highest among women aged 45–49 (240.3 per 10,000 woman-years), and for black women across all years."
  • A racial and age-wise breakdown of incident uterine fibroid case and noncase can be found in this table and this spreadsheet.

Prevalence of Uterine Fibroid Diagnoses in 2014

  • Total sample (number of women aged 18–65): 136,317
  • Number of women with Uterine fibroids (n): 13,142
  • Percentage of women with Uterine fibroids (%): 9.6%
  • The prevalence of fibroids in women was highest in the age group 50–54 years (15.9%). Prevalence in both the age groups 45–49 and 55–65 was 13.4%.
  • By race/ethnicity, the prevalence of fibroids was the highest among black women (18.5%) and lowest among white women (10.3%).
  • A complete breakdown of the prevalence of uterine fibroid diagnoses in the US in 2014 by age and race can be found in this table and this spreadsheet.

Journal of Women's Health

  • Another 2018 study on uterine fibroids in the US classified women into three cohorts: at-risk, diagnosed, and fibroid-related hysterectomy. This study indicates that the at-risk cohort was significantly younger and had significantly lower income and education levels, compared to the diagnosed and hysterectomy cohorts. The complete demographics and baseline clinical characteristics of study participants can be found here.

Summary of Findings

  • The initial research focused on finding the most recent data available on the demographic characteristics of US women with uterine fibroids. Sources such as Mayo Clinic, CDC, MedlinePlus, NIH, and research journals such as ScienceDirect, NCBI, American Journal of Obstetrics and Gynecology, and the Journal of Women's Health were consulted to find the latest available data on the demographics of women with uterine fibroids.
  • Two research studies published in the American Journal of Obstetrics and Gynecology and the Journal of Women's Health provided insights into the age, race/ethnicity, and income of women with uterine fibroids. However, no breakdown was found for different geographical locations.
