      STUDY DESIGN: This report is one in a set of reports summarizing data from the 2004 National Health Interview Survey (NHIS), a multipurpose health survey conducted by the National Center for Health Statistics (NCHS) of the Centers for Disease Control and Prevention (CDC). This report provides national estimates for the U.S. civilian noninstitutionalized population of adults. The NHIS has been an important source of information about health and health care in the U.S. since it was first conducted in 1957.
      All members of the household 17 years of age and over who are at home at the time of the interview are invited to participate and respond for themselves. For children and adults not available during the interview, information is provided by a knowledgeable adult family member (18 years of age or over) residing in the household.
      The interviewed sample for 2004 consisted of 36,579 households, which yielded 94,460 persons in 37,466 families. There were 37,388 adults eligible for the Sample Adult questionnaire. Data were collected for 31,326 adults, a conditional response rate of 83.8% (the number of completed Sample Adult interviews divided by the total number of eligible sample adults). The unconditional or final response rate for the Sample Adult Core component was calculated by multiplying the conditional rate by the overall family response rate of 86.5%, yielding a final Sample Adult component response rate of 72.5%.
      LIFETIME PREVALENCE: The total number of subjects (in thousands) who had ever been told by a doctor or other health professional that they had asthma was reported as 21,300 (crude rate, 9.9%; age-adjusted rate, 9.9%). The number of cases was reported as follows for selected demographic variables, with the age-adjusted rate in parentheses: males, 8796 (8.5%); females, 12,503 (11.2%); ages 18-44 years, 10,959 (9.9%); ages 45-64 years, 6973 (10.0%); ages 65-74 years, 1893 (10.3%); ages 75 and over, 1474 (9.1%); whites, 17,376 (9.7%); blacks, 2755 (11.2%); Hispanics/Latinos, 2013 (7.9%); less than high school education, 3227 (10.5%); bachelor’s degree or higher, 4706 (9.2%); family income less than $20,000, 4554 (12.5%); family income $75,000 or more, 4439 (9.5%); poor, 2260 (13.4%); not poor, 11,200 (9.9%). The prevalence was reported as follows by health insurance coverage. Under age 65 years: private, 11,962 (9.5%); Medicaid, 2081 (17.0%); uninsured, 2963 (8.6%). Age 65 and over: private, 1996 (9.5%); Medicaid and Medicare, 348 (18.0%); Medicare only, 771 (8.6%).
      CURRENT PREVALENCE: The total number of subjects (in thousands) who had ever been told they had asthma and still had asthma was reported as 14,358 (crude rate, 6.7%; age-adjusted rate, 6.7%). The number of cases was reported as follows for selected demographic variables, with the age-adjusted rate in parentheses: males, 5148 (5.0%); females, 9210 (8.2%); ages 18-44 years, 7058 (6.4%); ages 45-64 years, 4871 (7.0%); ages 65-74 years, 1368 (7.5%); ages 75 and over, 1061 (6.6%); whites, 11,750 (6.6%); blacks, 1890 (7.7%); Hispanics, 1163 (4.6%); less than high school education, 2386 (7.8%); bachelor’s degree or higher, 3053 (5.9%); family income less than $20,000, 3467 (9.6%); family income $75,000 or more, 2838 (6.0%); poor, 1742 (10.3%); not poor, 7209 (6.3%).
