Abstract
Objective
To design a replicable training protocol for visual estimation of fruit and vegetable
(FV) intake of kindergarten through second-grade students through digital photography
of lunch trays that results in reliable data for FV served and consumed.
Methods
Protocol development through literature and researcher input was followed by 3 laboratory-based
trainings of 3 trainees. Lunchroom data collection sessions were done at 2 elementary
schools for kindergarten through second-graders. Intraclass correlation coefficients
(ICCs) were used.
Results
By training 3, ICC was substantial for amount of FV served and consumed (0.86 and
0.95, respectively; P < .05). The ICC was moderate for percentage of fruits consumed (0.67; P = .06). In-school estimates for ICCs were all significant for amounts served at school
1 and percentage of FV consumed at both schools.
Conclusions and Implications
The protocol resulted in reliable estimation of combined FV served and consumed using
digital photography. The ability to estimate FV intake accurately will benefit intervention
development and evaluation.
