  1. How to Get and Use C.L.A.S.S (Classification of Laws Associated • with School Students) • http://class.cancer.gov/ April Oh1, Frank Perna2, June 27, 2011 1Clinical Research Directorate/CMRP, SAIC-Frederick, Inc., NCI-Frederick, Inc., Frederick, MD 21702 2 National Cancer Institute, DCCPS, BRP, Rockville, MD 20852

  2. What is C.L.A.S.S.? Classification of Laws Associated with School Studentshttp://class.cancer.gov/ • Classification system of codified state laws • Includes two systems coding Physical Education/Recess and Nutrition policies: • Physical Education-Related State Policy Classification System (PERSPCS) • School Nutrition Environment State Policy Classification System (SNESPCS) • All 50 states and Washington DC • Grade levels: Elementary, Middle and High School

  3. C.L.A.S.S. Policies

  4. Who Goes to C.L.A.S.S.?

  5. 2003-2008 data, tool, and codebook NOTE: *2010 Data Currently Being Coded*

  6. C.L.A.S.S. users can select PE or nutrition, grade level, policy area, and year to generate customized national maps of codified state-laws

  7. National Policy Map Download maps for: PowerPoint Policy reports Newsletters Download into PDF • Please insert PRINT SCREEN OF A PDF PRINTED MAP • CIRCLE BUTTON FOR VIEW/PRINT PDF

  8. Using C.L.A.S.S. Data • Key • State variable • Consider • Population sampled • Sampling methodology • Policy lag • Data Sets • SHPPS (School Health Policies and Programs Survey) • U.S. Census • Youth Risk Behavior Surveillance System/Youth Risk Behavior Survey (YRBSS/YRBS) • U.S. Department of Educational Statistics

  9. Example: BMI and State PE Laws • Purpose • Examine relationship between state-laws for time spent in school physical education (PE) class and adolescent weight status • National Survey of Children’s Health (NSCH) • Noninstitutionalized children and adolescents • Ages 0 to 17 years • 50 states and the District of Columbia • Cross sectional survey data collected 2003, 2007; oversampled urban areas, telephone survey

  10. Example 2: Continued • Policy Lag and Variables Used • NSCH 2007 – Weight Status • PERSPCS 2005 – PE time requirements • Selected Middle School Students • Results • Inverse relationship between weight status (r=- 0.02, p<0.05) and stringency of PE time state laws • Relationship between state law and weight status: • Significant among Black students (r=-.03, p<0.001) • Not significant among Whites students (r=-.01, p=0.17)

  11. Example: Linking PE Law with Practices in Public Schools Perna, Oh, Agurs-Collins, Dodd, Nebeling, Moser, Chriqui, Masse, Atienza

  12. Question? Do schools within states with higher C.L.A.S.S. PE-Time scores report more PE-time than schools within states with relatively lower PERSPCS scores?

  13. Methods Secondary Data Analysis of: PERSPECS Score (2005) • State Law regarding public School PE policy • http://class.cancer.gov/ SHPPS (School Health Policy and Programs Survey) School Level Data (Public Schools) 2006 • School practices (minutes of physical education) • School demographic characteristics: size, urbanicity, poverty level • http://www.cdc.gov/HealthyYouth/shpps/index.htm

  14. SHPPS Measures Dependent Variable: Time Spent in PE • Time = Weeks x Days x Minutes/ 36 Weeks Derived from

  15. PERSPCS Classification

  16. Elementary School Level

  17. Questions You May Explore? What is relationship between a State’s C.L.A.S.S. score(s) and: • Change in policy scores over time?...weighted by population? • Average student/teacher ratio • Achievement test scores in ES, MS, HS? • Amount spent per pupil on education? • Child poverty rate? • Obesity rate?
