June 2007

Better information about the prevalence of and trends in chronic illness is needed for rural Americans. This study used data from the Behavioral Risk Factor Surveillance System (BRFSS) to examine the prevalence of and trends in asthma, by type of geographic location and by key risk factors. The aim was to determine the prevalence of and trends in asthma among all rural BRFSS respondents and also among rural minority group members and residents of remote rural counties.

For this study, annual BRFSS data from 1994 to 2003 were used. Chi-square testing was used to compare unadjusted prevalence rates of each condition or screening by geographic category and race/ethnicity. Logistic regression analyses were performed to compare outcomes adjusted for sociodemographic, health and health care system factors. Trend assessment included time (in years) as an additional covariate in models. The Final Report for this project is available from the WWAMI RHRC website.
