  1. Overweight among Ohio 3rd Grade Students,2004-2005 Elizabeth J. Conrey, RD, PhD Maternal and Child Health Epidemiologist Ohio Department of Health

  2. Pediatric Overweight • Tripled 1970s to current • Comorbidities in childhood • Predictive of adult overweight

  3. Why collect statewide BMI data on schoolchildren? • Establish baseline • No Ohio data on school aged population • Standardize the process • Collect accurate data • Save resources at the local level

  4. Why collect statewide BMI data on schoolchildren? • Track childhood overweight in Ohio over time • Target resources to groups with greatest risk • Evaluate success of interventions • Provide feedback to schools, communities and other stakeholders • Influence state and local policy

  5. What is BMI? • Excess body fat • Consistent and valid measure • Relative measure of height and Weight • For children • Consider AGE and SEX also • Calculate Percentile

  6. Methods • 2004-2005 school year • BMI Assessment was added to state 3rd Grade Oral Health Survey • Efficient • Saved resources • Limit intrusion on class time

  7. Sampling: Schools • Provide state and county level estimates (88 counties) • Stratification to ensure schools with >50% of students FRPM eligible were represented • Cluster sampling • Schools chosen PPS sampling without replacement within counties • If a chosen school refused participation, another school was chosen

  8. Sampling: Students • All children within sampled schools selected • Active permission • Parent/guardian reported child’s • Date of birth and age in years • Sex • Race • Ethnicity • Eligibility for FRMP

  9. Getting To Yes Contact Superintendent Contact SchoolPrincipal Site Visit to School Nutrition & PA Education Materials Mailed Permission Forms Mailed Permission Slips Collected Height & Weight Measured

  10. Recruitment & Training of Screeners • Volunteer health care professionals recruited from each community • WIC • Child & Family Health Services (CFHS) • School Nurses • Volunteers trained on protocol • ODH Guidelines were standard • Train the trainer sessions • Training also by video

  11. Recruitment & Training • Volunteer health care professionals recruited from each community • WIC • Child & Family Health Services (CFHS) • School Nurses • Volunteers trained on protocol • ODH Guidelines were standard • Train the trainer sessions • Training also by video

  12. BMI Assessment • Medical grade scales and stadiometer purchased by ODH • Height to nearest ¼ inch • Weight to nearest 0.2 lb • Measured twice and averaged • Students could not see weight readout • No results sent home with child

  13. Data Analysis • Age in months calculated from birthdate and date of assessment • CDC growth charts to generate BMI-for-age and sex percentiles

  14. Data Analysis • SUDAAN to estimate proportions, standard errors, χ2 tests for differences between groups • Analyses weighted on race & FRPM

  15. Response • Schools • 392 Schools were approached • 387 Schools participated • Students….

  16. 27,660 Total Enrollment in Sampled Schools 12,170 No Form Returned 16,464 Permission Forms Returned 1,255 BMI Permission Denied 15,209 Granted BMI Permission 666 Not Screened 14,543 Screened for BMI 3 Lacking Height or Weight 14,539 BMI Calculated 38 Lacking Sex or Age Data 14,501 BMI Percentile Calculated 14,451 Final BMI Sample Size 50 Implausible BMI for Age & Sex

  17. Ohio 3rd Graders by Weight Status, 2004-5

  18. Overweight among Ohio 3rd Graders by Sex, 2004-5

  19. Overweight among Ohio 3rd Graders by Race & Ethnicity, 2004-5 * * Different from NH White and Hispanic by χ2, p< 0.05

  20. Overweight among Ohio 3rd Graders by Free & Reduced Price Meal (FRPM) Eligibility, 2004-5 * * Different by χ2, p< 0.05

  21. Overweight among Ohio 3rd Graders by County Type, 2004-5 * * Different from rural non-App and suburban by χ2, p< 0.05

  22. Limitations • School participation • Low response rate (returned consent) • PPS sampling was based on the total number of students in the school

  23. Conclusions • Over 1/3 of Ohio 3rd graders are overweight or at risk of overweight • Rural Appalachian counties have the highest overweight prevalences • Lower SES children have higher overweight prevalences • State prevalence comparable to national

  24. Now What? • Call to Action • Families • Schools • Communities • Health Care Providers • Local Governments • Data used to target resources • ODH state plan to address childhood overweight • Continued data collection • The report:www.healthyohioans.org/schools/schools.aspx
