Overview
The incidence of ARDS in the United States is estimated at approximately 75 cases per 100,000 individuals, which amounts to roughly 150,000 new cases annually.[1] There is substantial variance in the rates of ARDS between different countries and geographic regions due to factors such as mean life expectancy, prevalence of different risk factors and comorbidities, and access to healthcare.
Epidemiology and Demographics
Incidence
No reliable international comparative epidemiological data of ARDS are available because of the evolution of the diagnostic criteria. The incidence of ARDS as defined by the Berlin definition remains unclear.
Worldwide, the incidence of ARDS ranges from a low of 1.5 per 100,000 persons per year to a high of 75 per 100,000 persons per year. Most studies suggest an incidence rate of approximately 2 to 8 cases per 100,000 persons per year.

Age
Patients of all age groups may develop ARDS, however, it occurs more commonly in the elderly.
Gender
Women are slightly more commonly affected with ARDS than men, however, the mortality rate is slightly higher among men than women.[2][3]
Race
There is no racial predilection to the development of ARDS. However, in the United States the mortality rate among African Americans with ARDS is higher than among whites.[2]
