National Youth Physical Activity and Nutrition Study (NYPANS)
NYPANS Results
The National Youth Physical Activity and Nutrition Study (NYPANS) was conducted in 2010 with three main purposes:
- To provide nationally representative data on behaviors and behavioral determinants related to nutrition and physical activity among high school students
- To provide data to help improve the clarity and strengthen the validity of questions on the Youth Risk Behavior Survey (YRBS)
- To understand the associations among behaviors and behavioral determinants related to physical activity and nutrition and their association with body mass index
The study included three measures:
- A paper-and-pencil questionnaire [pdf 170K] administered to a nationally representative sample of students attending public and private schools in grades 9–12
- Standardized protocol to measure height and weight in students completing the questionnaire
- Telephone interviews to measure 24-hour dietary recalls among a subsample of students
Data & Documentation
The Data User’s Manual [pdf 3.3M] includes a sample description, procedures for editing the data, descriptions of how the variables were calculated, analysis software technical notes, and four codebooks: one for the survey and height/weight measurements, and three for the 24-hour dietary recall interview data files. Each data file is available in SAS, SPSS, and Access.
