Key variables of interest include markers of self-regulation, substance use, and externalizing behaviors in adolescents.
Objective To explore the relationships between maternal smoking during pregnancy and adolescent behavioral outcomes. To examine associations between postpartum environmental tobacco smoke exposure and adolescent behaviors. Datasets The datasets used in this project should contain variables related to maternal smoking, cotinine levels, and various adolescent behaviors. Key variables include:
Mom_Smoke_p: Binary indicator of maternal smoking during pregnancy. cotimean_34wk: Cotinine concentration at the 34th week of pregnancy. cotimean_pp6mo and cotimean_pp6mo_baby: Cotinine levels in mothers and babies at 6 months postpartum, respectively. Behavioral markers: Bpm_att, Erq, cig_ever, e_cig_ever, mj_ever, alc_ever, swan_hyperactive, and Bpm_ext. Analysis Sections
