Prevalence of asthma in the US population, 1988-1991.
Am J Epidemiol 1996 Jun; 143(11)(Suppl):S17
The Third National Health and Nutrition Examination Survey (NHANES III), 1988-1994, provides national data for respiratory conditions among the civilian noninstitutionalized population of the United States. NHANES III, a 6-year survey measuring the health and nutrition status of the U.S. population, was conducted by the. National Center for Health Statistics. NHANES III data consists of two data sets: phase I (1988-1991) and phase 2 (1992-1994). The prevalence of asthma was estimated from the phase I data of household interview surveys. For proper estimates of standard errors of the asthma prevalence, the SUDAAN program was used incorporating sample weights and accommodating the multiple stage sample design of the survey. Of the 9,487 sampled adults, 20 years of age and older, the overall prevalence of asthma was 7.6% (95% CI, 7.3 - 7.9%). Asthma was more prevalent among men (7.8%) than women (7.5%). By ethnicity it was lower among Mexican Americans (5.0%) than non-Hispanic whites (8.0%) and non-Hispanic blacks (7.3%). The asthma prevalence was substantially higher among smokers (8.0%) and former smokers (7.9%) than non-smokers (7.2%). Among industries of which 40 or more employees were sampled, asthma was most prevalent among nursing and personal care facilities (16.6%). Other industries with high prevalence of asthma include elementary and secondary schools (12.0%), automotive repair shops (9.2%), justice, public order and safety (8.6%), machinery industries (8.5%), and eat and drinking places (8.1 %). These findings provide useful information for asthma prevention strategies and for hypothesis generation for future work-related asthma studies.
