Abstract
Objective
To determine whether fourth-grade students participating in the Shaping Healthy Choices Program (SHCP), a school-based nutrition intervention, would change vegetable and carotenoid
intake measured by skin carotenoids and dietary intake.
Methods
Single-group pretest–posttest with a self-selected, convenience sample of students
(n = 30) participating in the SHCP, which lasted 1 academic year (9 months). Dietary
intake of vegetables and carotenoids as measured by Block food frequency questionnaire
and skin carotenoids as measured by Raman spectroscopy were collected at the school
preintervention and postintervention.
Results
Reported carotenoid intake decreased by 1.5 mg (P = .05) and skin carotenoids decreased by 2,247.9 RRS intensity units (P = .04). Change in reported intake correlated with change in skin carotenoids (r = .43; P = .02).
Conclusions and Implications
The reported decrease in vegetable and carotenoid intake was unanticipated; nevertheless,
the RRS measurements confirmed this. RRS data can help evaluate changes in fruit and
vegetable intake.
