Code for 'Food-insecure women eat a less diverse diet in a more temporally variable way: Evidence from the US National Health and Nutrition Examination Survey, 2013-4'

Nettle, Daniel; Bateson, Melissa

Code to reproduce the analyses in the study 'Food-insecure women eat a less diverse diet in a more temporally variable way: Evidence from the US National Health and Nutrition Examination Survey, 2013-4'

The analysis requires two R scripts available here, plus original 2013-4 NHANES data files, downloadable from the NHANES website (https://wwwn.cdc.gov/nchs/nhanes/continuousnhanes/default.aspx?BeginYear=2013).

The first R script, 'merging script.r' takes the original NHANES files, extracts the variables required for the study, merges them into a single data frame, and saves this in .csv format. The NHANES files it requires are:

# Demographics, food insecurity and BMI
DEMO_H.XPT
FSQ_H.XPT
BMX_H.XPT

# Summary files of food recalls
DR1TOT_H.XPT
DR2TOT_H.XPT

# Individual foods files from food recalls
DR1FF_H.XPT
DR2FF_H.XPT

The second R script takes the .csv file output by the merging script, and reproduces the analyses and figures described in the paper.
