Parents play a significant role in adolescent health behaviors; however, few nutrition interventions for Hispanic adolescents involve parents. This study assessed the effects of a 10-week parenting intervention simultaneously targeting nutrition and substance use prevention. Hispanic parent/6th–8th-grade adolescent dyads (n = 239) were randomized to Families Preparing the New Generation Plus (FPNG+; nutrition/substance use prevention), FPNG (substance use prevention only), or Realizing the American Dream (RAD; academic success control). Surveys assessed diet, alcohol use, substance use intentions, and substance use norms at baseline (T1), immediately post-intervention (T2), and at 16 weeks post-intervention (T3). Latent change modeling assessed diet changes; adolescent substance use outcomes were assessed using effect sizes. Among adolescents, those in FPNG+ increased fruit (+0.32 cup equivalents, Individuals of Hispanic descent, now identified as the largest ethnic minority group in the United States (US) [Low diet quality is an important factor contributing to chronic disease risk [Diet-related behaviors, like many other health behaviors, are shared among different family members [The purpose of this study was to assess if Families Preparing the New Generation Plus (FPNG+), a parenting intervention designed to target adolescent healthy eating and substance use prevention simultaneously, can be efficacious with two different outcomes: healthy eating (i.e., estimated intake of fruit, vegetables/legumes, whole grains, fiber, dairy, and added sugars overall and from beverages) among participating parents and their adolescent children, as well as adolescent-reported substance use-related outcomes. The FPNG+ intervention is guided by the ecodevelopment theory [
