Texas School Physical Activity and Nutrition Survey (TX SPAN)

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.

Who conducts it?

The TX SPAN Project is conducted by researchers at 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, with funding from the Texas Department of State Health Services (DSHS).

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.

Texas Researchers Provide Startling Data Behind Why Over 25% of Latino Kids Have Childhood Obesity

Childhood obesity is getting worse over time, especially for Latinos. Researchers in Texas (39.4% Latino) recently released a data explorer that illustrates trends in body mass index of school-aged children in their state (52% Latino).
