(1) Chronic Disease estimates for 2000 and 2001 CANNOT BE COMPARED TO EACH OTHER. Between the release dates of these two publications, the National Health Interview Survey completely redesigned their questionnaire and obliterated all trends. Therefore, estimates prior to 1997 cannot be compared with later estimates. The 2000 estimates were obtained from the 1996 NHIS survey while the 2001 estimates were obtained from the revised 1998 NHIS survey. (2) Adult Asthma disease estimates for 2001 and 2002 CANNOT BE COMPARED TO EACH OTHER. The 2001 estimate utilizes the National Health Interview Survey questionnaire while the 2002 estimate utilizes the Behavioral Risk Factor Surveillance System Survey. (3) Pediatric Asthma estimates for 2004 CANNOT BE COMPARED to 2000-2003 data. The 2004 estimate represents current asthma prevalence while the past three years of data measured asthma attack prevalence. (4) Several states changed the length of their monitored ozone seasons. The 2004 report uses the revised season lengths to calculate grades. However no grades were affected by the change.
