Seminar title is: “The Delta Garden Study: Results and Challenges.”

Adverse health outcomes, including childhood obesity, require new strategies for enhancing children’s and adolescents’ adherence to the Dietary Guidelines for Americans. The primary aim of this study, the Delta Garden study, was to test the effectiveness of a science-based school garden program for increasing fruit and vegetable (FV) intakes of middle school students. The study used a quasi-experimental, repeated measures, nested, pair-matched design utilizing 6 intervention (school garden) schools and 6 control (no school garden) schools, including over 2,000 6th, 7th and 8th grade students nested within 4-6 science teachers per school. A self-report FV questionnaire (FVQ) was developed for use specifically with school garden programs, and was tested for validity (comparison with concurrent 24-hour recalls) and reliability (test-retest). Subsequently, the validated questionnaire was used to measure the proportion of students who had at least a ¼ cup increase in fruit and vegetable intake from the previous time-point (baseline, midpoint, final). Here the validity of the FV questionnaire, main results and some of the challenges faced from the Delta Garden Study will be presented.
