Note. Project EAT = Eating and Activity in Teens. The weighted 1999 sample used inverse probability weighting based on the odds of being in the 2010 sample given the demographics. Weighting was done to allow for an examination of secular trends in fast-food restaurant use independent of demographic shifts in the population (see text in Statistical Analysis section). Both the unweighted and weighted 1999 demographics are provided for ease of comparison.
P values are presented for differences between the weighted 1999 and 2010 samples, based on the χ2 test for ethnicity/race and household education.
Mothers could choose more than 1 ethnic/racial category; those responses indicating multiple categories were coded as mixed/other. Because there were few participants who identified themselves as Hawaiians, Pacific Islanders, or Native Americans, these participants were also included in the mixed/other category.
