Abstract
Objective
To determine if counting and goal setting can increase red/orange vegetable intake.
Design
Pre-posttest experimental.
Setting
Midwestern university.
Participants
Undergraduate students (n = 165).
Intervention
Those in the intervention group (n = 85) were asked to count the number of times they
ate red/orange vegetables and set a goal to eat 1 more time.
Main Outcome Measure
An estimate (number of times/d) of vegetable intake based on an independent review
of uploaded photographs and descriptions of meals from smartphones.
Analysis
Generalized estimating equations.
Results
For the intervention group, mean frequency intake increased from 0.9 times/d on Monday
to 1.6 times/d on Tuesday and to 1.3 times/d on Wednesday, whereas mean intakes for
the control group were 1.0, 0.8, and 0.8 times/d, respectively. There were significant
group × time interactions for Tuesday (β = 0.8; P < 0.001) and Wednesday (β = 0.5; P = 0.006).
Conclusions and Implications
A mobile method that helped people count their daily red/orange vegetable intake and
set a goal appeared to increase consumption. This finding suggests that nutrition
education programs that provide people with easy ways to track specific dietary behaviors
might be effective at helping them attain goals.
