Sex differences in asthma prevalence and other disease characteristics in eight states

Objectives . We assessed the sex differences in asthma prevalence and asthma-control characteristics within eight states. Methods . We analyzed data from the 2001 Behavioral Risk Factor Surveillance System survey. Results . Lifetime and current asthma prevalence were higher for females in each of the eight states compared to males. Adult onset of asthma was reported more often by females with current asthma, and childhood onset was reported more often by males. Sex differences were identified for the eight asthma-control characteristics. Conclusions . Females in eight states presented higher asthma risk and poorer asthma profiles than males. State surveillance data can be used to identify disparities and to develop appropriate public health interventions.
