Reflection spectroscopy is an emerging, non-invasive objective measure used to approximate fruit and vegetable intake. The present study aimed to use a reflection spectroscopy device (the Veggie Meter®, Longevity Link Corporation, Salt Lake City, UT, USA) to assess skin carotenoid status in preschool, middle- and high-school students and to examine associations between skin carotenoids and self-reported dietary intake.
In Autumn 2018, we used the Veggie Meter® to assess skin carotenoids and age-appropriate validated dietary assessment measures to approximate fruit and vegetable (FV) intake. Preschool participants completed a previously validated pictorial liking tool using an iPad (Apple Inc., Cupertino, CA, USA). Middle-school participants completed selected questions from the validated School Physical Activity and Nutrition (SPAN) (Michael & Susan Dell Center for Healthy Living, University of Texas, Austin, TX, USA) questionnaire regarding frequency of their FV and beverage intake on the previous day, with additional questions about physical activity. High-school participants' FV intake was assessed using the Fruit and Vegetable Screener (National Cancer Institute, Bethesda, MD, USA). Spearman correlation coefficients were used to determine bivariate associations between measures of dietary intake and Veggie Meter®-assessed skin carotenoid levels.
Mean (SD) Veggie Meter® readings were 266 (82.9), 219 (68.1) and 216 (67.2) among preschool, middle- and high-school students. There was an inverse association between soda intake and Veggie Meter® readings (r = -0.22, P = 0.03) among middle-school students; and a positive association between daily fruit intake and Veggie Meter® readings (r = 0.25, P = 0.06) among high-school students.
The Veggie Meter® comprises a promising evaluation tool for preschool and school-based nutrition interventions.
反射光谱学是一种新兴的非侵入性客观测量方法，用于近似水果和蔬菜的摄入量。本研究旨在使用反射光谱仪（Veggie Meter ® ，长寿链接公司，盐湖城，犹他州，美国）评估学龄前、中学和高中生的皮肤类胡萝卜素状况，并研究皮肤类胡萝卜素与自我报告的饮食摄入量之间的关系。
2018 年秋季，我们使用 Veggie Meter ® 评估皮肤类胡萝卜素，并使用适合年龄的经过验证的饮食评估措施来近似水果和蔬菜（FV）的摄入量。学龄前儿童使用 iPad（苹果公司，库比蒂诺，加利福尼亚州，美国）完成了以前经过验证的图画喜好工具。中学生使用经过验证的学校体育活动和营养（SPAN）（迈克尔和苏珊戴尔健康生活中心，德克萨斯大学，奥斯汀，德克萨斯州，美国）问卷中的选定问题，回答前一天 FV 和饮料的摄入频率，以及有关体育活动的额外问题。高中生的 FV 摄入量使用水果和蔬菜筛选器（国家癌症研究所，贝塞斯达，马里兰州，美国）进行评估。Spearman 相关系数用于确定饮食摄入量和 Veggie Meter ® 评估的皮肤类胡萝卜素水平之间的双变量关联。
学龄前、中学和高中生的平均（SD）Veggie Meter ® 读数分别为 266（82.9）、219（68.1）和 216（67.2）。在中学生中，苏打水摄入量与 Veggie Meter ® 读数呈负相关（r = -0.22，P = 0.03）；在高中生中，每日水果摄入量与 Veggie Meter ® 读数呈正相关（r = 0.25，P = 0.06）。
Veggie Meter ® 是一种有前途的学龄前和基于学校的营养干预评估工具。
