Food-related parenting behaviors have the potential to impact youth eating behaviors and nutrition knowledge. The present study examined associations between parental behaviors specific to eating (i.e., rules, solicitation, and the creation of a health-focused home environment) and specific unhealthy eating behaviors prevalent during adolescence. Additional analyses examined whether such associations were explained by adolescent nutrition knowledge. A total of 145 adolescents ( M = 14.48, SD = 1.75 years) and their mothers ( M = 43.52, SD = 6.76 years) completed questionnaires as part of a larger study investigating parent-adolescent communication. Mothers' food-related parenting behaviors were not directly associated with adolescents' engagement in unhealthy eating behaviors. However, more parental rules were associated with greater adolescent nutrition knowledge. In addition, mothers' creation of a health-focused home environment was indirectly associated with less fast food consumption through greater adolescent nutrition knowledge. Implications and future directions are discussed.
