    Abstract:
    OBJECTIVE: The purpose of this impact evaluation was to measure the influence of a government of Ontario, Canada health promotion initiative, the Northern Fruit and Vegetable Pilot Programme (NFVPP), on elementary school-aged children's psychosocial variables regarding fruit and vegetables, and fruit and vegetable consumption patterns. DESIGN: A cluster-randomised controlled trial design was used. The NFVPP consisted of three intervention arms: (i) Intervention I: Free Fruit and Vegetable Snack (FFVS) + Enhanced Nutrition Education; (ii) Intervention II: FFVS-alone; and (iii) Control group. Using the Pro-Children Questionnaire, the primary outcome measure was children's fruit and vegetable consumption, and the secondary outcome measures included differences in children's awareness, knowledge, self-efficacy, preference, intention and willingness to increase fruit and vegetable consumption. SETTING/SUBJECTS: Twenty-six elementary schools in a defined area of Northern Ontario were eligible to participate in the impact evaluation. A final sample size of 1,277 students in grades five to eight was achieved. RESULTS: Intervention I students consumed more fruit and vegetables at school than their Control counterparts by 0.49 serving/d (P < 0.05). Similarly, Intervention II students consumed more fruit and vegetables at school than Control students by 0.42 serving/d, although this difference was not statistically significant. Among students in both intervention groups, preferences for certain fruit and vegetables shifted from 'never tried it' towards 'like it'. CONCLUSIONS: The NFVPP resulted in positive changes in elementary school-aged children's fruit and vegetable consumption at school, and favourable preference changes for certain fruit and vegetables.
