Figure 2.
Distribution of delivery outcomes by substance-related type in matched cohort of pregnant women from January 1, 2012 to August 31st, 2019 (n = 2,158). *Results show that opioid-, stimulant-, and any substance-related diagnoses were significantly associated with preterm delivery. Stimulant-, nicotine-, and any substance-related diagnoses were significantly associated with cesarean delivery. Alcohol-, opioid-, stimulant-, nicotine-, and any substance-related diagnoses were significantly associated with co-occurring preterm and cesarean delivery. A cannabis-related diagnosis was not significantly associated with preterm or cesarean delivery. The sample size and percentage for each substance by those with and without preterm and cesarean delivery can be found in Table 4.
