Aplicación y adaptación del Veggie Meter en entornos comunitarios: un estudio de métodos mixtos

Evaluation of public health nutrition interventions designed to increase fruit and vegetable intake (FVI) is critical to understanding and improving these projects. Challenges with self-reported dietary intake data and feasibility of biochemical assessments in community-based settings have led to use of skin carotenoid measurements as an alternative measure of FVI.

Understand how the Veggie Meter, a tool for measuring skin carotenoids, is applied and adapted for use in community-based settings to measure FVI.

This mixed-methods study applied a convergent parallel design. Quantitative data were collected via an online survey. Qualitative semi-structured interviews were conducted with individuals who had experience collecting Veggie Meter data in community-based settings.

Fourteen individuals with experience collecting data with the Veggie Meter in a community-based setting enrolled. Fourteen surveys were collected via Qualtrics and 10 audio-recorded interviews were conducted via Zoom from March through July 2023.

Descriptive statistics were calculated for survey results. A constructivist approach was applied to the qualitative interview data.

Fourteen individuals completed the survey, and of those individuals, ten also completed an interview. Three main themes were identified to describe application and adaption of the Veggie Meter in community-based settings: (1) balancing protocol adherence with contextual adaptation in Veggie Meter usage, (2) implementation and operation of the Veggie Meter in community-based settings, and (3) strategies for maximizing participant engagement with the Veggie Meter.

Use of the Veggie Meter for data collection in community-based necessitated adaptation of standard protocols to meet varied needs of the environments, communities, and participants where evaluation of public health nutrition interventions occurred.
