^aProject EAT (Eating and Activity in Teens) participants were adolescents recruited from Minneapolis/St.Paul middle and high schools during 2009/2010.

^bCell sizes vary due to a small amount of missing data for individual items; columns may not add to 100 due to rounding; Family meals based on 1-item assessing past week frequency of eating meals together with all or most of your family living in your house (never, 1-2, 3-4, 5-6, 7, or 7+ days/week).

^cParenting practice variables are dichotomous. Parent communication scale (score range=1-5) of 2-items assessing mother/father caring and comfort talking to parents about problems (1=not a lot, 2=a little, 3=somewhat, 4=quite a bit, 5=very much; High= a score of 4 or 5; Low is a score of 1-3); Home Availability based on 1-item assessing how frequently fruits and vegetables were available at home (1=never, 2=sometimes, 3=usually, 4=always); Home Accessibility based on 2-items assessing how frequently fruit was on counter, table or somewhere they could easily get it, and how often there were cut-up vegetables in the fridge (1=never, 2=sometimes, 3=usually, 4=always); Parent modeling based on 4-items assessing if mother/father eats a lot of fruit and eats vegetables with dinner (1=never, 2=rarely, 3=sometimes, 4=on a regular basis), and scores were based on having a least one parent model fruit or vegetable intake on a regular basis; Parent encouragement based on 2-items assessing if mother/father encourages them to eat healthy foods (1=not at all, 2=a little, 3=somewhat, 4=very much), and scores were based on having at least one parent very much encouraging healthy eating.
