Abstract
Objective: Web-based dietary interventions could support healthy eating. The Advice, Ideas and Motivation for My Eating (Aim4Me) trial investigated the impact of three levels of personalised web-based dietary feedback on diet quality in young adults. Secondary aims were to investigate participant retention, engagement, and satisfaction. Design: Randomised controlled trial. Setting: Web-based intervention for young adults living in Australia. Participants: 18-24-year-olds recruited across Australia were randomised to: Group 1 (control: brief diet quality feedback), Group 2 (comprehensive feedback on nutritional adequacy + website nutrition resources), or Group 3 (30-minute dietitian consultation + Group 2 elements). Australian Recommended Food Score (ARFS) was the primary outcome. The ARFS subscales and percentage energy from nutrient-rich foods (secondary outcomes) were analysed at 3, 6 and 12 months using generalised linear mixed models. Engagement was measured with usage statistics, and satisfaction with a process evaluation questionnaire. Results: Participants (n=1005, 85% female, mean age 21.7±2.0 years) were randomised to Group 1 (n=343); Group 2 (n=325), Group 3 (n=337). Overall, 32 (3%), 88 (9%) and 141 (14%) participants were retained at 3, 6, and 12-months, respectively. Only 52 participants (15% of Group 3) completed the dietitian consultation. No significant group-by-time interactions were observed (p>0.05). The proportion of participants who visited the 13 website pages ranged from 0.6% to 75%. Half (Group 2=53%, Group 3=52%) of participants who completed the process evaluation (Group 2, n=111; Group 3, n=90) were satisfied with the program. Conclusion: Recruiting and retaining young adults in web-based dietary interventions is challenging. Future research should consider ways to optimise these interventions, including co-design methods.
