目的：为了确定是否四年级学生参与塑造健康的选择计划（SHCP），以学校为基础的营养干预，将改变蔬菜和类胡萝卜素的摄入量测量皮肤类胡萝卜素和膳食intake.Methods：单组前测后测与一个自我选择的，方便的样本的学生（n = 30）参与SHCP，历时1学年（9个月）。饮食摄入量的蔬菜和类胡萝卜素块食物频率问卷测量和皮肤类胡萝卜素测量拉曼光谱收集在学校preintervention.Results：报告类胡萝卜素摄入量减少1.5毫克（P = 0.05）和皮肤类胡萝卜素减少2247.9 RRS强度单位（P = 0.04）。报告的摄入量的变化与皮肤类胡萝卜素的变化相关（r = .43; P = .02）。结论和影响：报告的蔬菜和类胡萝卜素摄入量的减少是意料之外的，然而，RRS测量证实了这一点。RRS数据可以帮助评估水果和蔬菜摄入量的变化。
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.
