The Child Feeding Guide:A digital health intervention for reducing controlling child feeding practices and maternal anxiety over time

Fussy eating and food refusal are common in young children. These behaviours can contribute to anxiety or concern in parents and caregivers, who have called for credible support to help them navigate the challenges of feeding young children. Given recent increases in technology, and use of the Internet as a trusted source of parenting support, the Child Feeding Guide digital health intervention was created to provide evidence-based support to parents and caregivers to help them to feed children and establish healthy eating habits from the early years. An evaluation was conducted with 25 mothers (with a child aged 6 months to 4 years) who used the Child Feeding Guide website/app over 4 weeks. Mothers provided information about their feeding practices and anxiety levels at baseline, and again 4 weeks later, and answered questions regarding the acceptability and use of the digital support resource. Significant decreases were seen in maternal anxiety and in maternal use of pressure to eat and restriction of food from children for weight reasons. Mothers reported that the Child Feeding Guide was easy to use, that they valued its credibility and reassurances, and that its content helped them to better understand their child’s eating behaviour. These promising findings suggest that naturalistic use of a digital health intervention could contribute to reductions in mothers’ use of controlling feeding practices and levels of anxiety. Such findings are important for supporting the development of healthy eating habits in young children and are likely to be relevant to health and childcare professionals

Dynamics of bootstrap percolation

Bootstrap percolation transition may be first order or second order, or it may have a mixed character where a first order drop in the order parameter is preceded by critical fluctuations. Recent studies have indicated that the mixed transition is characterized by power law avalanches, while the continuous transition is characterized by truncated avalanches in a related sequential bootstrap process. We explain this behavior on the basis of a through analytical and numerical study of the avalanche distributions on a Bethe lattice.Comment: Proceedings of the International Workshop and Conference on Statistical Physics Approaches to Multidisciplinary Problems, IIT Guwahati, India, 7-13 January 200

If at first you don't succeed:Assessing influences associated with mothers' reoffering of vegetables to preschool age children

Repeatedly offering vegetables has been shown to be one of the most effective methods for increasing acceptance and subsequent intake in young children. In order to increase successful offerings of vegetables and resultant consumption amongst young children, it is necessary to consider the influences on maternal reoffering of vegetables. This study aimed to investigate the relationships between mothers' tendency to reoffer vegetables and a range of demographic factors and psychological variables. A cross-sectional design was used, where mothers completed questionnaires assessing how often they reoffer rejected vegetables, concerns for economic factors, and a range of possible child and maternal influences. Mothers of preschool children were recruited from toddler groups across Leicestershire, UK, as well as online. Spearman's correlations were run to look for associations between demographic and psychological factors with maternal reoffering of vegetables. Significantly associated factors were then entered into a stepwise regression to predict maternal reoffering of vegetables. Mothers were significantly less likely to reoffer rejected vegetables if they were concerned about time, money, and waste, were influenced by their child's mood, or were concerned about their child having tantrums. Moreover, mothers who consumed more vegetables themselves reoffered vegetables more frequently. Regression analyses revealed that mothers' concern about food waste and tantrums, as well as maternal vegetable consumption, all significantly predicted mothers' reoffering of vegetables. With these findings in mind, mothers should be educated and supported with how to tackle and minimise children's tantrums during feeding, as well as being made aware of effective methods for avoiding food waste. Moreover, given that mothers' own vegetable consumption is associated with lower reoffering of vegetables to their child, interventions which seek to increase familial vegetable consumption should be pursued

Investigating the role of parent and child characteristics in healthy eating intervention outcomes

While numerous studies have investigated the efficacy of interventions at increasing children's vegetable consumption, little research has examined the effect of individual characteristics on intervention outcomes. In previous research, interventions consisting of modelling and rewards have been shown to increase children's vegetable intake, but differences were identified in terms of how much children respond to such interventions. With this in mind, the current study investigated the role of parental feeding practices, child temperament, and child eating behaviours as predictors of intervention success. Parents (N = 90) of children aged 2-4 years were recruited from toddler groups across Leicestershire, UK. Parents completed measures of feeding practices, child eating behaviours and child temperament, before participating in one of four conditions of a home-based, parent led 14 day intervention aimed at increasing their child's consumption of a disliked vegetable. Correlations and logistic regressions were performed to investigate the role of these factors in predicting intervention success. Parental feeding practices were not significantly associated with intervention success. However, child sociability and food fussiness significantly predicted intervention success, producing a regression model which could predict intervention success in 61% of cases. These findings suggest that future interventions could benefit from being tailored according to child temperament. Furthermore, interventions for children high in food fussiness may be better targeted at reducing fussiness in addition to increasing vegetable consumption

Teaching our children when to eat:how parental feeding practices inform the development of emotional eating-a longitudinal experimental design

Background: Emotional eating in children has been related to the consumption of energy-dense foods and obesity, but the development of emotional eating in young children is poorly understood. Objectives: We evaluated whether emotional eating can be induced in 5-7-y-old children in the laboratory and assessed whether parental use of overly controlling feeding practices at 3-5 y of age predicts a greater subsequent tendency for children to eat under conditions of mild stress at ages 5-7 y. Design: Forty-one parent-child dyads were recruited to participate in this longitudinal study, which involved parents and children being observed consuming a standard lunch, completing questionnaire measures of parental feeding practices, participating in a research procedure to induce child emotion (or a control procedure), and observing children's consumption of snack foods. Results: Children at ages 5-7 y who were exposed to a mild emotional stressor consumed significantly more calories from snack foods in the absence of hunger than did children in a control group. Parents who reported the use of more food as a reward and restriction of food for health reasons with their children at ages 3-5 y were more likely to have children who ate more under conditions of negative emotion at ages 5-7 y. Conclusions: Parents who overly control children's food intake may unintentionally teach children to rely on palatable foods to cope with negative emotions. Additional research is needed to evaluate the implications of these findings for children's food intake and weight outside of the laboratory setting. This trial was registered at clinicaltrials.gov as NCT01122290

Is dual use of nicotine products and cigarettes associated with smoking reduction and cessation behaviours? A prospective study in England

Objectives: To investigate associations of dual use of e-cigarettes and cigarettes with subsequent quitting activity (smoking reduction, quit attempts and use of evidence-based cessation aids). To overcome potential confounding by factors associated with use of pharmacological support, we selected dual use of over-the-counter nicotine replacement therapy (OTC NRT) and cigarettes as a behavioural control. / Design: Prospective cohort study with 6-month follow-up. / Setting: England, 2014–2016. / Participants: 413 current smokers participating in the Smoking Toolkit Study, a representative survey of adults in England, who reported current use of e-cigarettes or OTC NRT and provided data at 6-month follow-up. / Main: outcome measures The exposure was dual use of e-cigarettes or OTC NRT at baseline. Outcomes were change in cigarette consumption, quit attempts and use of evidence-based cessation aids during quit attempts over 6-month follow-up. Relevant sociodemographic and smoking characteristics were included as covariates. / Results: After adjustment for covariates, dual e-cigarette users smoked two fewer cigarettes per day at follow-up than at baseline compared with dual OTC NRT users (B=2.01, 95% CI −3.62; −0.39, p=0.015). While dual e-cigarette users had 18% lower odds than dual OTC NRT users to make a quit attempt at follow-up (risk ratio (RR) 0.82, 95% CI 0.67 to 1.00, p=0.049), the groups did not differ in use of cessation aids (RR 1.06, 95% CI 0.93 to 1.21, p=0.388). / Conclusions: Dual use of e-cigarettes is associated with a greater reduction in cigarette consumption than dual use of OTC NRT. It may discourage a small proportion of users from making a quit attempt compared with dual OTC NRT use but it does not appear to undermine use of evidence-based cessation aids
