This difference was less apparent for school year 2008‐2009, where the asthma rates were 14.4% among students in grade PK or K, 13.5% in grade 6 or 7, and 12.2% in grade 9, 10 or 11. • Asthma prevalence rates were higher among male students when compared to female students. For school year 2008‐2009, the asthma rates were 14.5% among male students and 11.6% among female students. • In regard to asthma prevalence rates by race/ethnicity, Hispanic students had the highest rates of asthma followed by black students, other race/ethnicity students, and white students. For school year 2008‐2009, the asthma rates were 16.9% among Hispanic students, 14.8% among black students, 12.2% among students of other race/ethnicity, and 10.6% among white students. Please note that about 8.8% of students were reported as having an unknown race/ethnicity category; therefore, asthma prevalence rates by race/ethnicity groups could potentially be underestimated. • District Reference Groups (DRG), with letters A to I, classify school districts of similar socioeconomic status (SES). In general, SES decreases with each letter from A to I, and asthma rates increased with decreasing SES. Four of the five largest cities (Bridgeport, Hartford, New Haven, and Waterbury) belonged to group I, which had the highest asthma rates. For school year 2008‐2009, the asthma rates ranged from 7.4% among students in DRG A to 19.2% among students in DRG I. • In public and private schools, the majority of asthma cases were reported as mild. In general, the percentage of students with exercise induced asthma increased as grade increased. • Males consistently showed higher percentages of mild asthma while females showed higher percentages of exercise induced asthma. • In general, the percent of students with mild asthma was highest among whites, while the percent of students with moderate asthma was highest among blacks. Exercise induced asthma was more prevalent in white students than black and Hispanic students. • About three out of every four students had an asthma diagnosis from Health Assessment Record; one out of every three students had asthma medication on file; and one out of every twenty students had an Asthma Action Plan on file. 1 Connecticut School-based Asthma Surveillance Report 2010 Introduction Pursuant to Connecticut General Statute (CGS) Section 10‐206, the State of Connecticut Department of Public Health (DPH) Asthma Program has established a statewide School‐based Asthma Surveillance System (SBASS) based on the school Health Assessment Record (HAR). The Statute also requires the Asthma Program to report the results of this surveillance to the joint standing committees of the General Assembly every three years. This report summarizes the information collected during school years 2006‐2007, 2007‐2008 and 2008‐2009. Description of the School‐based Asthma Surveillance System CGS §10‐206 requires that public schools report to the DPH, on an annual basis, information on students with asthma. A student is considered as having asthma if he/she meets any of the following conditions: 1) has a provider’s diagnosis of asthma indicated on the HAR, 2) has a provider medication order for asthma medication on file, 3) has an Asthma Action Plan (AAP) on file, 4) shows symptoms of asthma, 5) has a parental note on file indicating the child has asthma, or 6) any other indications that the child is suffering from asthma. Information on students with asthma to be reported include: grade, age, sex, race, ethnicity, asthma severity, diagnostic source, and school. This information is only reported for students with asthma in grades requiring an HAR: Pre‐Kindergarten (PK) or Kindergarten (K) for elementary schools, grade 6 or 7 for middle schools, and grade 9 or 10 or 11 for high schools (HAR requirement for high schools was changed to grade 9 or 10 from grade 10 or 11 at the beginning of the 2008‐2009 school year). In order to facilitate this process, DPH and the State Department of Education (SDE) developed reporting forms for the school nurses to use (see Appendix 1). These forms are distributed to individual school nurses through the school district nurse supervisors. School district nurse supervisors collect completed forms in their school districts and submit the forms to the DPH by September for the previous school year. All data are entered into SBASS, a Microsoft Access database, by trained DPH staff. Data quality checks are then performed to ensure the accuracy and completeness of the data entered. Methods for Asthma Rate Calculations School districts choose which grades require an HAR based on the options provided by the legislation. More specifically, it is up to the district to decide whether to require an HAR for students in grades PK or K, 6 or 7, and 9 or 10 or 11. School nurses are required to submit asthma data on the grades that require an HAR only, but some submit data on the other grades as well. Starting in school year 2006‐2007, school district nurse supervisors were asked to report specifically which grades required an HAR in their districts. Asthma rates are calculated by dividing the number of students with asthma by the total number of children enrolled in the required grades in the district. However, for some districts, 2 Connecticut School-based Asthma Surveillance Report 2010 it was still unclear what grades to include in the rates calculation because the grades specified by the school district nurse supervisors as requiring an HAR may be different from the actual grades that were reported for students with asthma. For example, a district may have indicated that grade 6 was the required grade for asthma data to be submitted, and while some nurses within the district submitted asthma data for grade 6, others may have submitted asthma data for grade 7 instead. In other instances, the district may have indicated both grades 6 and 7 were the required grades for asthma data to be submitted, but only grade 6 asthma data was submitted.
