Idiopathic Thrombocytopenic Purpura (ITP) - US Prevalence
The adjusted incidence rate of Idiopathic Thrombocytopenic Purpura (ITP) is 0.0095% of the total population and the number of people with ITP in the U.S. are 31,065 people. Below is an overview of the findings.
- "The incidence of ITP in adults is approximately 66 cases per 1,000,000 per year."
- The number of adults in the U.S. diagnosed each year (incidence) with immune thrombocytopenia is estimated to be 3.3 per 100,000 adults.
- Among adults in the U.S. between the ages of 30-60 years diagnosed with chronic ITP, there are 2.6 cases among women for every case involving a male. For older adults, the number of men and women diagnosed are almost equal with 52% male to 48% female.
- There are 9.5 cases of adults with ITP per 100,000 at any time (prevalence).
- Among children, this is estimated to be 5.3 per 100,000. The number of children with ITP is usually equal to the number of children diagnosed with ITP annually because children with ITP usually recover from it.
- Each year in the U.S., of the children under the age of 15 years, between four to eight children per 100,000 children are affected by ITP.
- Children younger than 10 years make up 40% of all patients diagnosed with some form of ITP.
- "The age-adjusted prevalence of immune thrombocytopenic purpura (ITP) is estimated to be 9.5 per 100,000 persons" in the US.
- The number of people with ITP is estimated to be 31,065 and the estimated incidence rate is 0.0095%. (see calculations below)
U.S. Population According to the US Census Bureau
- The U.S. has an estimated population of 327,167,434 people as of July 2018.
We were able to find some statistics for the incidence rate of Idiopathic Thrombocytopenic Purpura (ITP) in the U.S., most of the statistics provided were either for adults or children with a specific age range.
Please note that the finding "The age-adjusted prevalence of immune thrombocytopenic purpura (ITP) is estimated to be 9.5 per 100,000 persons in the US" comes from a dated source, however, there is no more recent data publicly available that contravenes this.
U.S. population in 2018 = 327,167,434 people
Prevalence of ITP = 9.5 person per 100,000 = 9.5*10=95 people per million
Number of people with ITP = (327 million/1 million) x 95 = 31,065 people
Converting to Percentage=[31,065/327,000,000]*100=0.0095%
Hence, 0.0095% of Americans have ITP and the adjusted incidence rate of ITP is 0.0095% of the total population and the people with ITP in the U.S. are 31,065 people.
