The [[prevalence]] of hemophilia is estimated to be 20,000 cases in the United States annually. The age-adjusted prevalence of hemophilia in six US states (Oklahoma, Massachusetts, Colorado, Georgia, Louisiana, and New York) in 1994 was 13.4 cases per 100, 000 males. The [[incidence]] of hemophilia is estimated to be 1 in 5,000 male births for hemophilia A and 1 in 30,000 births for hemophilia B.

Overview

The prevalence of hemophilia is estimated to be 20,000 cases in the United States annually. The age-adjusted prevalence of hemophilia in six US states (Oklahoma, Massachusetts, Colorado, Georgia, Louisiana, and New York) in 1994 was 13.4 cases per 100, 000 males. The incidence of hemophilia is estimated to be 1 in 5,000 male births for hemophilia A and 1 in 30,000 births for hemophilia B.

Epidemiology and Demographics

Incidence

Prevalence

  • The age-adjusted prevalence of hemophilia in six US states (Oklahoma, Massachusetts, Colorado, Georgia, Louisiana, and New York) in 1994 was 13.4 cases per 100, 000 males.[1]
  • The prevalence of hemophilia in Swedish population was 13.7 per 100, 000 males in 1980.[1][5]
  • The prevalence of hemophilia in other countries identified through contact with specialized hemophilia treatment centers range from 9.7 to 20.5 per 100, 000 males.[1][6][7][8][9][10]

Mortality rate

  • In the United Kingdom, during 1977-1999, the all-cause mortality rate in severe hemophilia was higher than the corresponding age- and calendar year–specific all-cause mortality rate in the general male population by a factor of 2.69, while for patients with moderate/mild hemophilia it was increased by a factor of 1.19.[11]
  • The overall life expectancy of the patients with hemophilia did not notably change between 1972 and 2001.[12]
  • AIDS is the main cause of death (26%) and 22% of the deaths are because of hepatitis C.[12]
