AbstractObjective:The present study aimed to identify whether discretionary food consumption declined in an intervention focused primarily on promoting fruit and vegetable consumption. We also aimed to identify potential mediators explaining intervention effects on discretionary food consumption.Design:Secondary analysis of data from the ShopSmart study, a randomised controlled trial involving a 6-month intervention promoting fruit and vegetable consumption. Linear regression models examined intervention effects on discretionary food consumption at intervention completion (T2). A half-longitudinal mediator analyses was performed to examine the potential mediating effect of personal and environmental factors on the association between the intervention effects and discretionary food consumption. Indirect (mediated) effects were tested by the product of coefficients method with bootstrapped se using Andrew Hayes’ PROCESS macro for SPSS.Setting:Women were recruited via the Coles FlyBuys loyalty card database in socio-economically disadvantaged suburbs of Melbourne, Australia.Participants:Analyses included 225 women (116 intervention and 109 control).Results:Compared with controls, intervention participants consumed fewer discretionary foods at T2, after adjusting for key confounders (B = −0·194, 95 % CI −0·378, −0·010 servings/d; P = 0·039). While some mediators were associated with the outcome (taste, outcome expectancies, self-efficacy, time constraints), there was no evidence that they mediated intervention effects.Conclusions:The study demonstrated that a behavioural intervention promoting fruit and vegetable consumption among socio-economically disadvantaged participants was effective in reducing discretionary food intake. Although specific mediators were not identified, researchers should continue searching for mechanisms by which interventions have an effect to guide future programme design.

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 objective of the present research was to test the efficacy of Fruit & Veg $ense sessions in increasing fruit and vegetable consumption.DesignA wait-list randomised controlled trial was conducted (n 292). Intervention participants attended a Fruit & Veg $ense session and received newsletters at weeks 2 and 5 after attending the session. All participants completed an FFQ and a questionnaire measuring knowledge, attitudes, barriers and stage of change for fruit and vegetable consumption at baseline and 6 weeks.SettingHunter region of New South Wales, Australia.SubjectsTwo hundred and ninety-two parents with children of primary school age.ResultsThe intervention group significantly increased its mean consumption of fruit and vegetables by 0·62 servings compared with 0·11 in the control group (difference of 0·51, P = 0·001). Compared with the control group, there were significant increases in intervention participants’ knowledge of daily recommended servings (for fruit and vegetables) and serving size (for vegetables), improvement in stage of change for vegetable consumption and a decrease in the number of perceived barriers to fruit and vegetable consumption.ConclusionsFruit & Veg $ense is efficacious in increasing fruit and vegetable consumption among parents of primary-school children. The study adds significantly to the limited evidence regarding fruit and vegetable interventions and the feasibility of engaging peer educators to deliver community education sessions. A broader implementation trial to test the effectiveness of Fruit & Veg $ense is recommended.

AbstractObjectiveTo examine the potential efficacy of a brief telephone-based parental intervention in increasing fruit and vegetable consumption in children aged 3–5 years and to examine the feasibility of intervention delivery and acceptability to parents.DesignA pre–post study design with no comparison group. Telephone surveys were conducted approximately 1 week before and following intervention delivery.SettingParticipants were recruited through pre-schools in the Hunter region, New South Wales, Australia.SubjectsThirty-four parents of 3–5-year-olds received four 30-min interventional telephone calls over 4 weeks administered by trained telephone interviewers. The scripted support calls focused on fruit and vegetable availability and accessibility within the home, parental role modelling of fruit and vegetable consumption and on implementing supportive family eating routines.ResultsFollowing the intervention, the frequency and variety of fruit and vegetable consumption increased (P = 0·027), as measured by a subscale of the children's dietary questionnaire. The intervention was feasible to be delivered to parents, as all participants who started the intervention completed all four calls, and all aspects of the interventional calls, including the number, length, content, format and relevance, were considered acceptable by more than 90 % of parents.ConclusionsA brief telephone-based parental intervention to encourage fruit and vegetable consumption in pre-school-aged children may be effective, feasible and acceptable. Further investigation is warranted in a randomised controlled trial.
