A NIDA-funded analysis of eight states showed a significant association between rates of neonatal abstinence syndrome (NAS) and poor economic conditions. NAS is a series of uncomfortable symptoms experienced by newborns suffering from opioid withdrawal after their mothers used opioids during their pregnancies.
The study used data from all 580 counties in Florida, Kentucky, Massachusetts, Michigan, New York, North Carolina, Tennessee and Washington state from 2009-2015. Investigators cross checked economic data with NAS cases from both rural and metropolitan areas. Economic data included 10-year unemployment rates, and health data included counties designated as mental health clinician shortage areas.
