Abstract:
|
SPAN was designed to measure body mass index and related dietary and physical activity habits, knowledge, and attitudes in Texas school-aged children in grades 4, 8 and 11. The purpose of the study is to yield representative data at the Texas state level, to provide representative estimates for the Texas Department of State Health Services (TDSHS) health service regions, and to provide representative estimates comparing border and non-border counties in Texas. A complex survey design was implemented incorporating a multi-stage probability sample at the state level as well as by three major racial/ethnic groups: African American, Hispanic and White/Other. This paper provides an overview of the design and methods, sampling weights, and post-adjustment considerations of this school-based survey for the academic year 2009-2010 and describes the unique challenges of this project.
