MDD major depressive disorder, NSDUH National Survey on Drug Use and Health
Data source: US Department of Health and Human Services. National Survey on Drug Use and Health, public-use files, 2010 and 2018 [11]
aIn 2010 and 2018, MDD in past year is based on the variable AMDDEYR (“Adult: past year major depressive episode”). In 2010, employment status is based on the variable EMPSTAT4 (“Imputation revised employment status 18+”). In 2018, employment status is based on the variable IRWRKSTAT (“Employment status—imputation revised”). Results are weighted based on the variable ANALWT_C (“Final person-level sample weight”) for 2018 and on the variable AWTC10_C (“2010 analysis weight poststratified to 2010 census totals”) for 2010. Adults with unknown MDD status were excluded from analysis
bValues for 2010 varied slightly from previously published results because of ongoing revisions of the NSDUH data. Values for 2010 varied further because of the use of an updated weighting variable relative to previously published results. None of the study conclusions were impacted by the variations
cp < 0.001 for all changes. p values for the change across years are calculated using the two-sample z test for independent proportions
dTreatment rate was identified based on the variable AMHTXRC3 (“Received any mental health treatment in past year”)
