Relationship between cigarette smoking and childhood symptoms of inattention and hyperactivity/impulsivity in alcohol-dependent adults without attention-deficit hyperactivity disorder.

摘要

BACKGROUND: Symptoms of inattention and hyperactivity/impulsivity that fall below the DSM-IV diagnostic threshold for attention-deficit hyperactivity disorder (ADHD) may be associated with the high prevalence of smoking among individuals with alcohol dependence, yet no studies to date have examined the relationship between subthreshold ADHD symptoms and cigarette smoking in this group. We hypothesized that increasing levels of ADHD symptoms would be associated with increasing risk of lifetime smoking and nicotine dependence, concentration problems secondary to nicotine withdrawal, and maintenance of smoking. METHODS: Participants were alcohol-dependent adults (n = 242) who did not meet criteria for ADHD or a current Axis I disorder other than alcohol and nicotine dependence. All participants were involved in treatment for alcohol dependence but not smoking cessation. The Semi-Structured Assessment for the Genetics of Alcoholism was administered to collect demographic and smoking history data and to assess symptoms of ADHD and other psychiatric disorders. RESULTS: A higher number of self-reported ADHD symptoms were associated with increased likelihood of ever smoking (p = .026), nicotine dependence (p = .017), and impaired concentration as a symptom of nicotine withdrawal (p = .046). There was no relationship between the number of ADHD symptoms and classification as a former versus current smoker (p = .333). CONCLUSIONS: Childhood symptoms of inattention and hyperactivity/impulsivity are related to cigarette smoking and nicotine dependence among alcohol-dependent individuals at levels below the ADHD diagnostic threshold. Conceptualization of ADHD symptoms as occurring on a continuum may aid identification of and early intervention for individuals who are at highest risk for initiating smoking and developing nicotine dependence.
