Texas School Physical Activity and Nutrition Survey (TX SPAN).
Project Overview
Project Overview
The Texas School Physical Activity and Nutrition (TX SPAN) Project is a Texas-wide surveillance system which monitors trends in body mass index (BMI) of school-aged children in the 2nd, 4th, 8th, and 11th grades within racial/ethnic, gender, and geographic subpopulations. Funded by the Texas Department of State Health Services, and conducted by the Michael & Susan Dell Center for Healthy Living at The University of Texas Health Science Center at Houston (UTHealth) School of Public Health in Austin, TX SPAN survey data have been collected in Texas at five time points using a cross-sectional questionnaire (years 2000-2002, 2004-2005, 2009-2011, 2015-2016, 2019-2020). In addition to monitoring the prevalence of school-aged children with overweight and obesity in Texas, TX SPAN identifies factors in Texas students that may underlie obesity, including dietary behaviors, nutrition knowledge and attitudes, and physical activity.
Research details and past surveys are available on the Details tab (see above).

Project Details
TX SPAN is a surveillance system to monitor the prevalence of overweight/obesity in school-aged children in Texas. This surveillance system allows researchers to identify and track trends in childhood obesity. TX SPAN identifies factors in Texas students that may underlie obesity, including dietary behaviors; nutrition knowledge and attitudes; and physical activity. The current TX SPAN will include probability-based sampling of students in 4th, 8th, and 11th grade, with a concurrent sampling of 2nd grade student parents, and a Texas-Mexico border-specific sample. Papers detailing the main results of SPAN for 2015-2016 and 2019-2020 are currently in process.

What kind of information is collected during TX SPAN?
TX SPAN data collection consists of (1) administration of a questionnaire which assesses food choice behaviors; food selection skills; weight perceptions and practices; nutrition knowledge; attitudes about food and eating; and physical activity behaviors; (2) height and weight measurements; (3) and school environment observations including a vending machine audit, healthy signage observations, and a school-level health policy questionnaire.
