The prevalence of hemorrhoids and chronic constipation: an epidemiologic study.
Results showed that 10 million people in the United States complained of hemorrhoids, corresponding to a prevalence rate of 4.4%. In both sexes, a peak in prevalence was noted from age 45-65 yr, with a subsequent decrease after age 65 yr.
The development of hemorrhoids before age 20 yr was unusual.
Whites were affected more frequently than blacks, and increased prevalence rates were associated with higher socioeconomic status.
