Associations between child maltreatment, cigarette smoking, and nicotine dependence in young adults with a history of regular smoking

Purpose: The purpose of this study was to evaluate whether childhood maltreatment is associated with smoking behaviors and lifetime nicotine dependence and if associations are moderated by sex. We examined these associations among individuals who ever reported being regular smokers. Methods: Using data from the National Longitudinal Study of Adolescent to Adult Health, we examined relationships between retrospectively self-reported child maltreatment (parent/caregiver-perpetrated emotional, physical, sexual abuse, and neglect; and non-parent/caregiver-perpetrated sexual abuse) and self-reported smoking behaviors among individuals with a history of regular smoking. Outcomes were any current smoking in early adulthood (mean age = 28 years), current smoking in adolescent study waves only, adulthood only, and adolescence and adulthood (n = 3581); and lifetime history of nicotine dependence (n = 3594) per the Fagerstrom scale. Results: Poly-maltreatment (aRR for 2+ vs. 0 exposures = 1.20, 95% CI: 1.08, 1.34) was associated with lifetime nicotine dependence; associations between nicotine dependence and neglect and non-parent/caregiver sexual abuse by force were only present in women. Neglect and non-parent/caregiver sexual abuse by nonphysical threat were associated with continued smoking, and an association between non-parent/caregiver sexual abuse by physical force and continued smoking was also noted in women only. Women who experienced poly-maltreatment were less likely to report current smoking in adolescence but not adulthood. Conclusions: These data suggest in a nationally representative sample of ever regular smokers, child maltreatment is associated with outcomes that suggest an inability to quit smoking and some associations may vary by sex.
