Cigarette Smoking Cessation Counselling in Pregnant Smokers with Mental Illness/Substance Use Disorders.

Our objective was to determine if past-year mental illness and substance use disorders (SUD) among pregnant smokers predicted the probability of receipt of counselling for cigarette smoking cessation. A secondary analysis of data from the National Survey on Drug Use and Health 2016-2019 was conducted. We found that approximately 83% of pregnant smokers (N = 373) received screening for cigarette smoking, and 65% received cessation counselling. Having mental illness predicted the probability of receipt of counselling for smoking cessation in pregnant smokers (adjusted odds ratio [AOR]: 3.75; 95% confidence interval [CI]: 1.25-11.27). However, having SUD (alcohol [AOR: 2.30; 95%CI: 0.57-9.26] or illicit drug use [AOR: 1.32; 95%CI: 0.26-6.82]) or comorbid mental illness and SUD (AOR: 0.23; 95%CI: 0.03-2.03) was not associated with receipt of counselling for smoking cessation. Practice guidelines and policy initiatives are needed to reduce cigarette use and its related adverse health outcomes in pregnant smokers with SUD.
