Children are not consuming sufficient amounts of fruits and vegetables in their habitual diet. Methods derived from associative learning theories could be effective at promoting vegetable intake in pre-school children. The objective of the present study was to compare the effectiveness of different learning strategies in promoting the intake of a novel vegetable. Children aged between 9 and 38 months were recruited from UK nurseries. The children (n 72) were randomly assigned to one of three conditions (repeated exposure, flavourflavour learning or flavour -nutrient learning). Each child was offered ten exposures to their respective version of a novel vegetable (artichoke). Pre-and post-intervention measures of artichoke purée and carrot purée (control vegetable) intake were taken. At pre-intervention, carrot intake was significantly higher than artichoke intake (P, 0·05). Intake of both vegetables increased over time (P,0·001); however, when changes in intake were investigated, artichoke intake increased significantly more than carrot intake (P,0·001). Artichoke intake increased to the same extent in all three conditions, and this effect was persistent up to 5 weeks post-intervention. Five exposures were sufficient to increase intake compared to the first exposure (P,0·001). Repeated exposure to three variants of a novel vegetable was sufficient to increase intake of this vegetable, regardless of the addition of a familiar taste or energy. Repetition is therefore a critical factor for promoting novel vegetable intake in pre-school children.

Vegetable intake is generally low among children, who appear to be especially fussy during the pre-school years. Repeated exposure is known to enhance intake of a novel vegetable in early life but individual differences in response to familiarisation have emerged from recent studies. In order to understand the factors which predict different responses to repeated exposure, data from the same experiment conducted in three groups of children from three countries (n = 332) aged 4–38 m (18.9±9.9 m) were combined and modelled. During the intervention period each child was given between 5 and 10 exposures to a novel vegetable (artichoke puree) in one of three versions (basic, sweet or added energy). Intake of basic artichoke puree was measured both before and after the exposure period. Overall, younger children consumed more artichoke than older children. Four distinct patterns of eating behaviour during the exposure period were defined. Most children were “learners” (40%) who increased intake over time. 21% consumed more than 75% of what was offered each time and were labelled “plate-clearers”. 16% were considered “non-eaters” eating less than 10 g by the 5th exposure and the remainder were classified as “others” (23%) since their pattern was highly variable. Age was a significant predictor of eating pattern, with older pre-school children more likely to be non-eaters. Plate-clearers had higher enjoyment of food and lower satiety responsiveness than non-eaters who scored highest on food fussiness. Children in the added energy condition showed the smallest change in intake over time, compared to those in the basic or sweetened artichoke condition. Clearly whilst repeated exposure familiarises children with a novel food, alternative strategies that focus on encouraging initial tastes of the target food might be needed for the fussier and older pre-school children.

Globally, dental caries is one of the most prevalent diseases and is more common in children living in deprived areas. Dental caries is preventable, and guidance in the United Kingdom recommends parental supervised brushing (PSB): a collection of behaviors-including twice-daily toothbrushing with fluoridated toothpaste-that should begin upon eruption of the first tooth (approximately 6 to 12 mo of age) and for which children need to be helped or supervised by an adult until at least 7 y of age. The aim of this study was to explore parents' experiences of toothbrushing with their young children and to establish barriers and facilitators to PSB at individual, interpersonal, and environmental levels according to the theoretical domains framework. Qualitative semistructured interviews guided by the framework were conducted with 27 parents of young children (<7 y) in 2 deprived areas of the United Kingdom. Framework analysis was used. Parents were not aware of national guidance concerning their active involvement in toothbrushing; however, they did have detailed knowledge of toothbrushing practices for children, and their intentions were to brush their children's teeth themselves twice every day as part of a family routine. Nonetheless, parents' difficulties experienced in managing their children's challenging behavior and the environmental context of their stressful lives meant that many parents adopted a role of simply reminding their children to brush or watching them brush. As such, the main barriers to PSB among parents living in deprived areas were skills in managing their children's behavior and environmental influences on family life. The results of our study have clear implications for the development of appropriate interventions to address the modifiable barriers to improve parental adoption of PSB. The results of this study will be used to develop a behavior change intervention to encourage parental supervised brushing. The intervention-which is likely to be delivered through health practitioners rather than dental teams-will be developed to reduce dental caries among young children and will require evaluation in terms of its clinical and cost effectiveness.

BackgroundThe prevalence of infant obesity is increasing, but there is a lack of evidence-based approaches to prevent obesity at this age. This study tested the acceptability and feasibility of evaluating a theory-based intervention aimed at reducing risk of obesity in infants of overweight/obese women during and after pregnancy: the Healthy and Active Parenting Programme for Early Years (HAPPY).MethodsA feasibility randomised controlled trial was conducted in Bradford, England. One hundred twenty overweight/obese pregnant women (Body Mass Index [BMI] ≥25 kg/m2) were recruited between 10–26 weeks gestation. Consenting women were randomly allocated to HAPPY (6 antenatal, 6 postnatal sessions: N = 59) or usual care (N = 61). Appropriate outcome measures for a full trial were explored, including: infant’s length and weight, woman’s BMI, physical activity and dietary intake of the women and infants. Health economic data were collected. Measurement occurred before randomisation and when the infant was aged 6 months and 12 months. Feasibility outcomes were: recruitment/attrition rates, and acceptability of: randomisation, measurement, and intervention. Intra-class correlations for infant weight were calculated. Fidelity was assessed through observations and facilitator feedback. Focus groups and semi-structured interviews explored acceptability of methods, implementation, and intervention content.ResultsRecruitment targets were met (~20 women/month) with a recruitment rate of 30 % of eligible women (120/396). There was 30 % attrition at 12 months; 66 % of recruited women failed to attend intervention sessions, but those who attended the first session were likely to continue to attend (mean 9.4/12 sessions, range 1–12). Reaction to intervention content was positive, and fidelity was high. Group clustering was minimal; an adjusted effect size of −0.25 standard deviation scores for infant weight at 12 months (95 % CI: −0.16–0.65) favouring the intervention was observed using intention to treat analyses. No adverse events were reported.ConclusionsThe HAPPY intervention appeared feasible and acceptable to participants who attended and those delivering it, however attendance was low; adaptations to increase initial attendance are recommended. Whilst the study was not powered to detect a definitive effect, our results suggest a potential to reduce risk of infant obesity. The evidence reported provides valuable lessons to inform progression to a definitive trial.Trial RegistrationCurrent Controlled Trials ISRCTN56735429Electronic supplementary materialThe online version of this article (doi:10.1186/s12889-016-2861-z) contains supplementary material, which is available to authorized users.

Traffic related air pollution is detrimental to health and creates a substantial attributable mortality burden. It is suggested that a shift from motorised transport to active forms of travel will therefore have significant health benefits. Currently 46% of school journeys for primary aged children are made by car and this figure has risen steadily. Understanding barriers to active school travel (AST) is an important first step in developing behavioural interventions to increase active travel. The purpose of this study mode with a focus on identifying barriers and facilitators to AST. Twenty parents of primary school children (4-12 years) in the West Yorkshire region took part in semi-structured interviews regarding school travel, informed by the Theoretical Domains Framework. Framework Analysis was used to identify key themes in the data and to develop a ual and structural levels. Distance was the biggest barrier to AST. Time constraints were reported as the main barrier to parents accompanying children in AST, while concerns about safety deterred parents from allowing children to travel independently. The need to incorporate multiple jouneys, such as the work commute and/or multiple school drop-offs, while difficulty getting children into local schools meant further to travel for a number of parents. Findings suggest that interventions to promote AST may be particularly effective if tailored towards working parents.However, also addressing factors such as distance to school and school travel at a policy level may produce more significant shifts in behaviour.
