Objectives. We examined trends from 1999 to 2010 in adolescents' self-reported fast-food restaurant use alongsidematernal reports of fast-food consumption and purchasing from restaurants for family meals. Methods. Middle- and high-school student participants from Minneapolis- St Paul, Minnesota, represented diverse ethnic/racial and socioeconomic backgrounds. Adolescents completed classroom-administered surveys and maternal caregivers responded by phone or mail. Results. The overall prevalence of frequent fast-food consumption, defined as 3 or more times per week, decreased from 1999 to 2010 among adolescents (1999: 25%; 2010: 19%; P < .001) and maternal caregivers (1999: 17%; 2010: 11%; P < .001), but sociodemographic disparities were apparent. For example, the prevalence of frequent fast-food consumption remained highest and did not significantly decrease among Black or Native American youths. The overall prevalence of frequent fast-food purchases for family meals did not significantly decrease; large decreases were observed only among Hispanic families (1999: 18%; 2010: 6%; P < .001). Conclusions. In light of previous findings linking frequent fast-food consumption to greater weight gain and poor nutrition, the observed decreases in consumption are encouraging and interventions are needed to address observed disparities.
