Abstract
PURPOSE: Unhealthy eating is a major modifiable risk factor for noncommunicable diseases and obesity, and remote acculturation to U.S. culture is a recently identified cultural determinant of unhealthy eating among adolescents and families in low/middle-income countries. This small-scale randomized controlled trial evaluated the efficacy of the "JUS Media? Programme," a food-focused media literacy intervention promoting healthier eating among remotely acculturating adolescents and mothers in Jamaica. METHODS: Gender-stratified randomization of 184 eligible early adolescents and mothers in Kingston, Jamaica (i.e., 92 dyads: Madolescent.age = 12.79 years, 51% girls) determined 31 "Workshops-Only" dyads, 30 "Workshops + SMS/texting" dyads, and 31 "No-Intervention-Control" dyads. Nutrition knowledge (food group knowledge), nutrition attitudes (stage of nutritional change), and nutrition behavior (24-hour recall) were primary outcomes assessed at four time points (T1/baseline, T2, T3, T4) across 5 months using repeated measures analysis of covariances. RESULTS: Compared to control, families in one or both intervention groups demonstrated significantly higher nutrition knowledge (T3 adolescents, T4 mothers: mean differences .79-1.08 on a 0-6 scale, 95% confidence interval [CI] .12-1.95, Cohen's ds = .438-.630); were more prepared to eat fruit daily (T3 adolescents and mothers: .36-.41 on a 1-5 scale, 95% CI .02-.77, ds = .431-.493); and were eating more cooked vegetables (T4 adolescents and T2 and T4 mothers: .20-.26 on a 0-1 scale, 95% CI -.03-.50, ds = .406-.607). Postintervention focus groups (6-month-delay) revealed major positive impacts on participants' health and lives more broadly. CONCLUSIONS: A food-focused media literacy intervention for remotely acculturating adolescents and mothers can improve nutrition. Replication in Jamaica and extension to the Jamaican diaspora would be useful.
