Association of Smoking and Nicotine Dependence With Trauma and Posttraumatic Stress Disorder in a General Population Sample

This study is aimed at investigating the association between trauma, posttraumatic stress disorder (PTSD), smoking, and nicotine dependence. Data were collected in a representative population sample of 4075 adults aged 18 to 64 with the Composite International Diagnostic Interview. Findings show increased odds ratios (ORs) for smoking (OR: 1.28; 95% CI: 1.09-1.51) and nicotine dependence (OR: 1.52; 95% CI: 1.26-1.82) in traumatized persons, independent of PTSD. Persons with PTSD tended to have higher odds for smoking (OR: 2.12; 95% CI: 1.16-3.90) and nicotine dependence (OR: 2.70; 95% CI: 1.57-4.65), but also had lower rates for quitting smoking (OR: 0.38; 95% CI: 0.17-0.84) and for remission from nicotine dependence (OR: 0.18; CI: 0.05-0.63). We conclude that persons suffering from PTSD might need comprehensive aid in smoking cessation.
