The Effects of Young Adults Eating and Active for Health (YEAH): A Theory-Based Web-Delivered Intervention

The cost-effectiveness of an updated theory-based online health behavior intervention for new university students: U@Uni2

“…These effects may be very small, but over a lifetime can result in significant health gains that are extremely costeffective to implement. Similar small but positive effects have been found recently in other trials of online interventions aiming to reduce unhealthy behaviours in students (Kattelmann et al, 2014;Kypri et al, 2014). However, the U@Uni interventions remain unique amongst similar online health behaviour interventions in their demonstration of cost-effectiveness in addition to efficacy.…”

Systematic review of control groups in nutrition education intervention research

“…Trained peer leader club members offered 2 lunchtime social marketing sessions/week for 5 weeks discussing SNaX messages; film, poster handouts, bookmarks, parent-student activities.

Results of a 2-year randomized, controlled obesity prevention trial: Effects on diet, activity and sleep behaviors in an at-risk young adult population

“…One study conducted on 13 large university campuses used online mini-educational lessons to promote a non-diet approach to healthy weight maintenance; the 10-week intervention focused on eating, physical activity and stress and also included sleep content. 23 Overall, the intervention did not have an impact on BMI or weight status, but did yield small, immediate post-intervention improvements in diet, activity and sleep. Another 12-week study of 155 university students evaluated a multiple component intervention requiring participants to complete a contract identifying at least one behavior to improve in the next week (e.g., physical activity, alcohol misuse, sleep) in addition to behavioral self-monitoring; intervention results indicated favorable changes across several health behaviors.…”
