NutriStat: Nutritional Anthropometry Program

NutriStat is an open source re-creation of NutStat, a nutritional anthropomentry tool created by the Centers for Disease Control and Prevention (CDC) as part of the Epi Info™ suite of epidemiologic tools (see http://www.cdc.gov/epiinfo for more information). NutriStat allows public health professionals to determine z-scores and percentiles for children and adolescents using the CDC Growth References. Scores can be tracked for individuals over time so that a complete growth history can be recorded.

NutriStat can be run from a flash drive or it can be installed to a computer's operating system for added convenience. Users will also have the ability to generate z-scores and percentiles for external data not originally created in NutriStat. Several database types are supported including Microsoft Access, Microsoft SQL Server, and MySQL. For more information, see Frequently Asked Questions.

Statistical Output:
  • Body Mass Index (raw, z-score, and percentile)
  • Head Circumference
  • Height for Age
  • Weight for Age
  • Weight for Height
  • Subscapular skin fold for Age
  • Triceps skin fold for Age
  • Mid-upper arm circumference (z-for-age and z-for-height)

Our community is actively seeking volunteers to participate in code development, testing, and feedback.

The included growth reference database files contains the L, M and S values needed for the z-score calculations (except for legacy MUAC z-scores and statistics generated from the WHO 1978 data set). The CDC 2000 reference data set was produced by the U.S. Centers for Disease Control and Prevention, and the WHO Growth Reference data set was produced by the World Health Organization. For more information on the CDC reference data, please refer to http://www.cdc.gov/growthcharts/data_tables.htm. For more information on the WHO reference data, please refer to http://www.who.int/growthref/en/.

Legacy MUAC z-scores are calculated using formulas referenced from Bull. WHO, 1997, 75: 11-18 and Bull. WHO, 1997, 75: 333-342. (Note this does not refer to MUAC z-scores calculated using the WHO 2006 child growth standards.) See:

The charting capabilities of this application are done using the Dynamic Data Display library. See http://dynamicdatadisplay.codeplex.com/.
