Intention to change multiple health risk behaviors and predictors of behavior change in vocational education students.

No studies have examined vocational education students' intention to change multiple health risk behaviors and whether baseline characteristics predict behavior change. Paticipants were vocational education students in New South Wales, Australia. Students in the no-intervention control arm of a cluster randomized controlled trial completed an online survey at baseline and 6 months later. Of 450 participants (83.3%) who reported multiple health risk behaviors at baseline, one-third (33.1%) intended to change at least two risk behaviors within 6 months. Participants experiencing symptoms of anxiety [OR = 7.43, 95% CIs 1.26-43.87;  = 0.03] and who intended to change three to four risk behaviors [OR = 23.30, 95% CIs 4.01-135.40;  = 0.001] rather than one behavior had significantly greater odds of changing at least one behavior in 6 months. Interventions could support vocational education students to change behaviors they wish to as well as motivate them to address other risk behaviors.
