In these files, we included the code used to obtain the data presented in tables and figures in the main paper and its supplemental material. We also included the dataset codebook.

All the data used in this study are publicly available. We obtained the data from the Integrated Public Use Microdata Series website (https://nhis.ipums.org/nhis/). [1]

Below, we describe each of the Stata .do files. These .do files use the special bookmark comment –**#– to facilitate the inspection of its contents using Stata's Do-file Editor Navigation Control.

preprocess.do

• Describes the study sample creation and generation of variables of interest.

population_general_characteristics.do

• Estimates the study population characteristics by race and ethnicity.

annual_prevalence_estimation.do

• Estimates the annual prevalence by race and ethnicity of short and long sleep duration.

temporal_trends_analysis.do

• Estimates the annualized rate of change of each sleep duration prevalence by race and ethnicity, along with the racial and ethnic differences from 2004 to 2018.

temporal_trends_figures.do
