This presentation describes hypersensitivity pneumonitis (HP) mortality trends over the past 23 years, geographic distribution of mortality rates, and mortality risk by industry and occupation. We analyzed National Center for Health Statistics multiple-cause-of-death data for the period 19802002, for U.S. residents aged 15 years and older. Annual mortality rates were age-adjusted to the U.S. year 2000 population as the standard. Mortality rate time-trends were calculated using a linear regression model. Geographic mortality distribution was mapped using the geographic information system (GIS) software. Proportionate mortality ratios (PMRs) by usual industry and occupation, adjusted for age, sex, and race, were based on data from certain states having those data for the period 19851999. Overall age-adjusted mortality rates increased significantly (p<0.0001) between 1980 and 2002, from 0.09 to 0.29 per million. Ten states with the highest HP mortality rates are Wisconsin, Wyoming, Vermont, South Dakota, Idaho, Iowa, Minnesota, Utah, North Dakota, and Nebraska. Three counties in Wisconsin had the highest age-adjusted HP mortality rates, from 1.2 to 10.4 per million. Among industries, significantly elevated PMRs for HP occurred for agricultural productions, livestock (PMR=19.3) and agricultural production, crops (PMR=4.3). Among occupations, significantly elevated PMRs for HP occurred for farmers, except horticulture (PMR=8.1). These surveillance findings can be useful for generating epidemiologic research hypotheses and developing HP prevention and intervention strategies.
