Feasibility and Preliminary Efficacy of the Eating Advice to Students (EATS) Brief Web-Based Nutrition Intervention for Young Adult University Students: A Pilot Randomized Controlled Trial.

Young adult university students are a priority population for nutrition intervention. This study assessed the feasibility and preliminary efficacy of the EATS (Eating Advice to Students) brief (i.e., single use) web-based nutrition intervention for young adult university students. A 3-month pilot randomized controlled trial (RCT) was conducted with 124 students aged 17-35 from the University of Newcastle, Australia. Participants were randomized to EATS ( = 62) or attention control ( = 62). EATS aimed to improve four target eating behaviors (vegetables, fruit, discretionary foods, breakfast). Primary outcomes were feasibility (recruitment, retention, usage, program acceptability). Recruitment and retention numbers were recorded, the program acceptability was assessed by a process evaluation survey and the website usage was objectively tracked. Preliminary efficacy was assessed via changes in diet quality (primary), fruit, vegetables, discretionary foods and breakfast intake, measured using Food Frequency Questionnaire. Recruitment was completed in five weeks. Retention was 73% (90/124) at 3-months. Intervention participants used EATS 1.5 ± 1.0 times. Satisfaction with EATS was rated at 4.04 ± 0.74 (maximum five). Intervention participants significantly decreased the percentage energy/day from discretionary foods compared with control (-4.8%, 95%CI -8.6, -1.1, = 0.012, = -0.34). No significant between-group differences were observed for diet quality, fruit, vegetable or breakfast intakes. EATS demonstrated high feasibility, particularly for reach and acceptability. The university setting and a brief web-based intervention show promise in engaging young adults to improve their eating behaviors.
