CI = confidence interval; NSDUH = National Survey on Drug Use and Health; OR = odds ratio; SE = standard error; SPD = Serious Psychological Distress. Acute SPD reflected in past month; Recent SPD reflected in past year/not past month.
aAdjusted for age, education, income, marital status, and race, using categories as shown in Table 1; and calendar year (categorical).
bBased on 5442 women aged ≥18 who reported being pregnant at the time of the survey. All statistics other than raw counts have been weighted to account for the survey.
cUnadjusted OR for smoking among pregnant women reporting past-month SPD differed from OR for smoking among pregnant women reporting past-year/no past-month SPD (p = .0017). Adjusted estimates did not significantly differ (p = .17).
