Objectives were to assess web/computer‐based interventions’ effectiveness for adolescents (11–18y); identify which intervention element(s) made the most impact on nutrition‐related variables; and ascertain recommendations for research/practice. Online databases/journal archives were systematically searched using key words; related articles’ bibliographies manually searched. One author examined abstracts for review inclusion; both authors conducted quality assessments using USDA's National Evidence Library's guidelines for Research Design/Implementation. Initial article retrieval (n=37488) was reduced to 14 using inclusion/exclusion criteria. Randomized controlled trials (RCTs) for preventing weight gain (n=2), weight loss (n=2) had NS results; RCTs (n=6), Non‐RCTs (n=4) for healthy eating (HE) included significant and NS results for HE components. Optimal intervention duration couldn't be concluded. Studies lacking behavior theory (n=6) had NS (n=3), significant (n=3) results; those with behavior theory (n=8) had mostly significant results (n=7), some gender‐specific (n= 3). Neither setting nor parental involvement influenced outcomes. Research needs include studies with stronger design (randomization, power analyses, treatment fidelity, mediating variable measurements, long‐term evaluation) in order to develop computer‐based nutrition education best practices.
