Title: Centers for Disease Control and Prevention; "Youth Risk Behavior Surveillance---Selected Steps Communities, 2005." Morbidity and Mortality Weekly Report; V.56; No.SS-2; 2/23/07; p1
      STUDY DESIGN: The Youth Risk Behavior Surveillance System (YRBSS) monitors priority health-risk behaviors, general health status, and the prevalence of overweight and asthma among youth and young adults. YRBSS includes a national school-based survey conducted by CDC and state and local school-based surveys conducted by state and local education and health agencies.
      As a component of YRBSS, in 2005, communities participating in the Steps to a HealthierUS Cooperative Agreement Program (Steps Program) also conducted school-based surveys of students in grades 9 through 12 in their program intervention areas. These communities used a modified core questionnaire that asks about dietary behaviors, physical activity, and tobacco use and monitors the prevalence of overweight, diabetes, and asthma. This report summarizes results from surveys of students in 15 Steps communities that conducted surveys in 2005. The reporting period was January to May 2005.
      The national data set and each community data set were cleaned and edited for inconsistencies. Missing data were not imputed statistically. Of 13,953 completed questionnaires from the national YRBS, 36 failed quality control and were excluded from analysis, leaving 13,917 usable questionnaires.
      LIFETIME ASTHMA (ADOLESCENT POPULATION): Across surveys, the overall percentage of students who had ever been told by a doctor or nurse that they had asthma (i.e., lifetime asthma) ranged from 15.5% to 27.9% (median: 20.1%). Prevalence among female students ranged from 11.9% to 25.8% (median: 20.3%), and prevalence among male students ranged from 15.1% to 30.3% (median: 20.4%).
      CURRENT ASTHMA: The overall percentage of students with lifetime asthma who reported having either (1) asthma but no episode or attack or (2) an asthma episode or attack (i.e., current asthma) during the 12 months preceding the survey ranged from 10.9% to 19.7% (median: 15.9%). Prevalence among female students ranged from 9.4% to 21.5% (median: 16.9%), and prevalence among male students ranged from 10.4% to 18.2% (median: 15.5%).
      ASTHMA EPISODE OR ATTACK: The overall percentage of students with current asthma who had an asthma episode or attack during the 12 months preceding the survey ranged from 28.4% to 52.4% (median: 37.6%). Prevalence among female students ranged from 37.4% to 48.1% (median: 44.9%), and prevalence among male students ranged from 24.5% to 37.8% (median: 28.4%).
