We conducted a cluster randomised controlled trial of parents in 56 primary schools and community service centres (clusters) to evaluate the effectiveness of a single-session workshop on promoting more fruit and vegetable (FV) intake. A total of 803 parents were randomised to the FV intervention arm (16 clusters, n = 197), the more appreciation control arm (19 clusters, n = 270), or the less criticism control arm (21 clusters, n = 336). The FV intake of the FV arm was compared with that of the combined more appreciation or less criticism (MALC) arm. Both arms received a 2 h workshop: (i) the FV arm on increasing FV consumption and related food literacy; (ii) the MALC arm on increasing appreciation or reducing criticism of children. Primary outcomes were FV consumption per day in the past week assessed at baseline, 2-weeks, and 6-weeks. Secondary outcomes were behavioural determinants proposed by the Health Action Process Approach (HAPA), including outcome expectancies, self-efficacy, intention, and planning behaviour. The FV arm had a greater increase in FV consumption than the MALC arm, with large effect sizes (d: 0.97–1.08) and improvements in behavioural determinants with small effect sizes at all time points (d: 0.19–0.43). Our study was the first population-based randomised controlled trial to show that a brief, single 2 h HAPA-based workshop was effective in promoting fruit and vegetable intake in parents.

AbstractObjective:The aim of the current study was to evaluate the effect on frequency, variety and amount of vegetables served and staff’s food-related practices in the multicomponent BRA intervention.Design:Cluster randomised controlled trial, conducted between Spring 2015 and Spring 2016. For allocation of the kindergartens, a stratified block randomisation was used. Data were collected in three ways: (i) a questionnaire for pedagogical leaders assessing the variety and frequency of vegetables served, including staff’s food-related practices assumed to be related to vegetable intake; (ii) a questionnaire for kindergarten assistants assessing staff’s food-related practices; (iii) a 5-d weighted vegetable diary assessing amount of vegetables served in a department.Setting:The target group for this study was public and private kindergartens in the counties of Vestfold and Buskerud, Norway.Participants:A total of seventy-three kindergartens participated.Results:At follow-up I, the amount of vegetables served increased by approximately 20 g per person per day (P = 0·002), and the variety in served vegetables increased by one-and-a-half kind per month (P = 0·014) in the intervention group compared to the control group. No effects on the frequency of vegetables served or on staff’s food-related practices were found.Conclusions:The BRA intervention was successful in increasing the amount and variety of vegetables served within intervention kindergartens. Further research is needed to understand the mechanisms that can affect the staff’s food-related practices.

AbstractObjectiveThe 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.DesignA 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/SubjectsTwenty-six elementary schools in a defined area of Northern Ontario were eligible to participate in the impact evaluation. A final sample size of 1277 students in grades five to eight was achieved.ResultsIntervention 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’.ConclusionsThe 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.

AbstractObjectiveThe present analysis evaluates the overall appreciation and implementation of an intervention, Project Tomato, designed to maintain fruit and vegetable intake in children aged 8–9 years.DesignA random sample of fifty-four English primary schools (658 children) were randomised to either the intervention group or the control. The intervention group received a multi-component programme delivered in school by teachers and items sent home for parents/children. Dietary measurements were collected at baseline and follow-up. The intervention participants completed questionnaires on the intervention materials, to identify implementation and appreciation of the intervention, and other environmental mechanisms.SettingFifty-four primary schools were randomly selected, with twenty-seven schools allocated to the intervention group.SubjectsA total of 311 children received the intervention.ResultsImplementation of the intervention was low, 21·3 % of school items and 56·0 % of home items were implemented. The intervention materials were well received by teachers, parents and children. Other mechanisms that may affect fruit and vegetable intake were explored. Children who ate their main meal with their parents 3–7 nights/week on average consumed 37·6 (95 % CI 9·8, 65·4) g more fruit and vegetables than children who ate with their parents 0–2 times/week.ConclusionsImplementation of the trial components was poor. However, the results identified the importance of parental environment and mealtime structure on children's fruit and vegetable intake.
