  1. Sample size may vary across models due to missing responses. Mean values were adjusted for gender, race/ethnicity, SES, and age. R2 for base model ranged from 0.01 for fruits and vegetables to 0.19 for other sugar-sweetened beverages.
  2. * Substances include cigarette smoking, alcohol, and marijuana use in the last 12 months. 'Never used any' indicate those who never used any of the three substances in the last 12 months; 'Used only one', those that used any one substance; 'Used any two', those that use any two substances; 'Used all three', those that used all three substances in the last 12 months.
  3. † P value represents testing for differences in adjusted means of dietary practices by categories of multiple substance use (df = 3).
  4. Include kool-aid, fruit drinks, lemonade or energy drinks.
  5. ab Different superscripts indicate statistically significant differences between mean dietary practices by category of substance use.
