Childhood maltreatment also had an incremental effect on alcohol persistence risk among those with baseline alcohol dependence; individuals with more types of maltreatment were more likely to have persistent disorders, controlling for demographics only (AOR=1.29, 95% CI: 1.13–1.46) or demographics and other childhood adversities (AOR=1.31, 95% CI: 1.15–1.48). Although more maltreatment types were generally associated with greater risk, there was some variability in the risk between levels (Table 3). Similarly, more types of childhood maltreatment incrementally predicted nicotine persistence among those with baseline nicotine dependence, controlling for demographics only (AOR=1.19, 95% CI: 1.12–1.27), or demographics and other childhood adversities (AOR=1.19, 95% CI: 1.11–1.26). Again, despite a general positive trend, nicotine also evidenced some variability between levels (Table 3). Results were slightly stronger when the predictor did not include emotional neglect (controlling for demographics [alcohol: AOR=1.34, 95% CI: 1.16–1.54; nicotine: AOR: 1.25, 95% CI: 1.16–1.34] or demographics and other childhood adversities [alcohol: AOR=1.36, 95% CI: 1.18–1.56; nicotine: AOR: 1.24, 95% CI: 1.16–1.33]).
