Validation of 2 Brief Fruit and Vegetable Assessment Instruments Among Third-Grade Students

Validity of short food questionnaire items to measure intake in children and adolescents: a systematic review

“…The studies by Flood et al . and Lim et al . did not report kappa statistics, whereas Antonogeogros et al .…”

“…Additionally, Hendrie et al (18) reported a kappa of 0.76, classifying it as good agreement. The studies by Flood et al (24) and Lim et al (26) did not report kappa statistics, whereas Antonogeogros et al (22) reported very good agreement (kappa values of 0.9 or above) for food groups of refreshments/juices, starchy products, fish and fruit.…”

“…The statistical approach varied between studies but most commonly utilised t-tests to assess group differences and/or testing of association (Tables 4 and 5). Only 14 studies utilised tests of agreement between methods, with five of these performing Bland-Altman analyses (18,22,(24)(25)(26) . Tools were assessed in terms of their ability to accurately estimate food/beverage or food/beverage group intake based on the interpretation of one or more of the statistical tests presented ( Table 4 and 5).…”

Using Skin Carotenoids to Assess Dietary Changes in Students After 1 Academic Year of Participating in the Shaping Healthy Choices Program

“…While numerous intervention studies aimed at increasing fruit and vegetable intakes in children have been conducted, the assessment of changes in dietary behavior in children remains a challenge. [5][6][7] Reported dietary intake is often used in community-based interventions, however it can be unreliable, and it is time and labor intensive. [8][9][10][11] Skin carotenoid status measured by resonance Raman spectroscopy (RRS) can be used as a biomarker to assess fruit and vegetable intake because carotenoids are predominately found in fruits and vegetables and their presence in the body can reflect cumulative dietary intakes of these foods.…”
