Trial Outcomes & Findings for Summer Harvest Adventure: A Garden-based Obesity Prevention Program for Children Residing in Low-resource Communities (NCT NCT05367674)
NCT ID: NCT05367674
Last Updated: 2026-06-30
Results Overview
Change in fruit and vegetable intake as assessed by dermal skin carotenoid scores using Raman Spectroscopy (Pharmanex NuSkin Biophotonic Scanner model S3). Dermal skin carotenoid scores range 10,000-85,000, with higher scores indicating higher skin carotenoid levels.

PRIMARY outcome
Timeframe: Baseline and 10 weeksPopulation: Outcome analyses included only participants with non-missing data; outcome data were missing for 3 participants in the MSP group who completed the study visit but did not have all measures collected.
Change in fruit and vegetable intake as assessed by dermal skin carotenoid scores using Raman Spectroscopy (Pharmanex NuSkin Biophotonic Scanner model S3). Dermal skin carotenoid scores range 10,000-85,000, with higher scores indicating higher skin carotenoid levels.

SECONDARY outcome
Timeframe: Baseline and 10 weeksChange in family engagement as assessed by the Expressed Emotion Adjective Checklist. The Expressed Emotion Adjective Checklist (EEAC) is a self-reported measure of expressed emotions. Twenty items are summed to a total score (range 20-140); higher scores indicate more positive expressed emotion (better outcome).
