ABSTRACT
In three European cohort studies, there was a lower prevalence of fibroids than in those examining U.S. populations. A German cohort study found 10.7% of women of mean age 40 years reported being diagnosed with a fibroid (20). An Italian cohort study found 21.4% of women, aged 30 to 60 years, with a uterus had ultrasonographically detectable fibroids (21), while a Swedish study found only 7.8% of women, between 33 and 40 years of age, had ultrasonographically detectable fibroids (22).
