National Youth Physical Activity and Nutrition Study (NYPANS)

The National Youth Physical Activity and Nutrition Study (NYPANS) was conducted in 2010 with three main purposes:

  1. To provide nationally representative data on behaviors and behavioral determinants related to nutrition and physical activity among high school students
  2. To provide data to help improve the clarity and strengthen the validity of questions on the Youth Risk Behavior Survey (YRBS)
  3. To understand the associations among behaviors and behavioral determinants related to physical activity and nutrition and their association with body mass index


The NYPANS study included three measures:

  1. A paper-and-pencil questionnaire [PDF – 170 KB] administered to a nationally representative sample of students attending public and private schools in grades 9–12
  2. Standardized protocol to measure height and weight in students completing the questionnaire
  3. Telephone interviews to measure 24-hour dietary recalls among a subsample of students



The Data User’s Manual [PDF – 3.3 MB] 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.

For more information about the system used to collect 24-Hour Dietary Recall data, see Nutrition Data System for Research (NDSR).

Survey and Height/Weight

Contains data from the paper and pencil questionnaire and the height and weight measurements. File sizes range from 4.6M to 16.2M.

(Use of the Survey SAS dataset also requires the Survey format library [sas7bdat – 165 KB].)

Food Group Serving Count

Contains food group serving counts at the whole food level (FGSCFood), the meal or eating occasion level (FGSCMeal), and the record level (FGSCRecord). Files sizes range from 3.7M to 53.1M.

Nutritional Analysis

Contains nutrient data at the whole food level (Food), the meal or eating occasion level (Meal), the component/ingredient level (Component), and the record level (Record). File sizes range from 5.4M to 70.8M.

One Record

Contains the same data as FGSCRecord, but while FGSCRecord contains 1 record per recall occasion, One_Record contains 1 record per respondent. File sizes range from 6M to 9.3M.
