Background Asthma control in African Americans (AA) is considered more difficult to achieve than in Caucasian Americans(CA).The aim of this study was to compare asthma control over time among AA and CA children whose asthma is managed per NAEPP (EPR-3) guidelines.Methods This was a one-year prospective study of children referred by their primary care physicians for better asthma care in a specialty asthma clinic.All children received asthma care per NAEPP guidelines.Results were compared between CA and AA children at baseline and then at three-month intervals for one year.Results Of the 345 children,ages 2-17 years (mean=6.2±4),220 (63.8％) were CA and 125 (36.2％) were AA.There were no significant differences in demographics other than greater pet ownership in CA families.At baseline,AA children had significantly more visits to the Emergency Department for acute asthma symptoms (mean =2.3 ±3) compared to CA(1.4 ± 2.3,P =0.003).There were no other significant differences in acute care utilization,asthma symptoms (mean days/month),or mean asthma control test (ACT) scores at baseline.Within 3-6 months,in both groups,mean ACT scores,asthma symptoms and acute care utilization significantly improved (P ＜ 0.05 for all) and change over time in both groups was comparable except for a significantly greater decrease in ED visits in AA children compared to CA children (P =002).Conclusion Overall,improvement in asthma control during longitudinal assessment was similar between AA and CA children because of consistent use of NAEPP asthma care guidelines.
