Age shows a trend toward significance (B = 0.038, SE = 0.020, 95% CI = [−0.002, 0.077], p = 0.063), while the male gender and income-to-need ratio do not significantly predict tobacco use initiation (B = −0.002, SE = 0.022, 95% CI = [−0.045, 0.042], p = 0.931; B = 0.023, SE = 0.022, 95% CI = [−0.020, 0.067], p = 0.290).
