2017 NSCH Data Release

2017 NSCH Data Release

NSCH Data File Enhancements

Attention: Revised 2017 NSCH data files were released on 4/24/2024, and are available below. 

2017 Screener Data and Input Files

2017 Topical Data and Input Files

Note: To ensure readability, please add ".sas7bdat" to the end of SAS 'data files' after downloading (i.e. "nsch_2017_screener.sas7bdat" and "nsch_2017_topical.sas7bdat"). If STATA file downloads are unsuccessful, please try an alternative browser.

Note: In both individual year and multi-year analyses, the NSCH sample size may be limited for smaller populations (e.g., AI/AN) and state-level subgroups or rare outcomes (e.g. adolescent CSHCN or autism in a particular state). Small sample sizes may produce unstable estimates. To minimize misinterpretation, we recommend only presenting statistics with a sample size or unweighted denominator of 30 or more. Further, if the 95% confidence interval width exceeds 20 percentage points or 1.2 times the estimate (≈ relative standard error >30%), we recommend flagging for poor reliability and/or presenting a measure of statistical reliability (e.g. confidence intervals or statistical significance testing) to promote appropriate interpretation.

Now available on Data Page: 2017 SAS and STATA files, 2017 NSCH Variable and Frequencies lists, 2017 Data User FAQs, updated Guide to Multiple Imputed Data Analysis, updated Guide to Multi-Year Analysis.

Corrected 2017 NSCH Data for Breastfeeding, Formula, and Solid Food

In data released between 2016 and 2021, a processing error caused the reported time in months for breastfeeding, age of first formula, and introduction of solid foods to be incorrectly rounded down by 1 in most cases.

Now available on Technical Documentation page: 2017 Methodology report, 2017 Source and Accuracy Statement, 2017 Nonresponse bias analysis.
