Good Grubbin’: impact of a TV cooking show for college students living off campus.

OBJECTIVE:
To determine if a series of 4 15-minute, theory-driven (Social Cognitive Theory) cooking programs aimed at college students living off campus improved cooking self-efficacy, knowledge, attitudes, and behaviors regarding fruit and vegetable intake.

DESIGN:
A randomized controlled trial with pre-, post- and follow-up tests.

SETTING:
University campus.

PARTICIPANTS:
Students (n = 101) from upper-level nonhealth courses (n = 37 male and n = 94 living off campus).

INTERVENTION:
The intervention group (n = 50) watched 4 weekly episodes of the cooking show, Good Grubbin'. The control group (n = 51) watched 4 weekly episodes on sleep disorders.

MAIN OUTCOME MEASURES:
Demographic information; knowledge, self-efficacy, motivations, barriers of eating fruits and vegetables; self-efficacy, motivations, barriers and behaviors of cooking; fruit and vegetable intake food frequency questionnaire.

ANALYSIS:
Repeated-measure analysis of variance and chi-square analyses were used to compare outcome variables.

RESULTS:
There were significant improvements in knowledge of fruit and vegetable recommendations in the intervention group compared to the control group postintervention and at 4-month follow-up (P < .05). There were no significant changes in fruit and vegetable motivators, barriers, self-efficacy or intake.

CONCLUSIONS AND IMPLICATIONS:
A television show on nutrition and cooking may be influential in changing students' knowledge, but it seems to have little impact on dietary behaviors. With a recent increase in popularity of cooking shows, future research should investigate the impact an extended cooking and nutrition show series might have on young adult viewers.
