Preliminary validation of the pica, ARFID and rumination disorder interview ARFID questionnaire (PARDI-AR-Q).

Background: The Pica, ARFID, and Rumination Disorder Interview (PARDI) is a structured interview that can be used to determine diagnosis, presenting characteristics, and severity across three disorders, including avoidant/restrictive food intake disorder (ARFID). The purpose of this study was to evaluate the psychometric properties of a questionnaire focused specifically on ARFID (PARDI-AR-Q), which has the potential to provide related information with less participant burden.

Methods: Adolescents and adults (n = 71, ages 14-40 years) with ARFID (n = 42) and healthy control participants (HC, n = 29) completed the PARDI-AR-Q and other measures.

The factor structure and validity of a diagnostic interview for avoidant/restrictive food intake disorder in a sample of children, adolescents, and young adults.

Objective: There is a paucity of validated diagnostic interviews for avoidant/restrictive food intake disorder (ARFID) to aid identification and classification of cases for both clinical and research purposes. To evaluate the factor structure, construct validity, and criterion validity of the Pica ARFID and Rumination Disorder Interview (PARDI; ARFID module), we administered the PARDI to 129 children and adolescents ages 9-23 years (M = 16.1) with ARFID (n = 84), subclinical ARFID (n = 11), and healthy controls (n = 34).

Development of the Pica, ARFID, and Rumination Disorder Interview, a multi-informant, semi-structured interview of feeding disorders across the lifespan: A pilot study for ages 10-22.

Objective: Avoidant/restrictive food intake disorder (ARFID), pica, and rumination disorder (RD) were added to the revised DSM-5 Feeding and Eating Disorders chapter in 2013. We developed a structured interview-the Pica, ARFID, and Rumination Disorder Interview (PARDI)-to assess the presence and severity of these diagnoses for evaluation and treatment planning in clinical and research settings. Here, we describe the development of the PARDI and provide a preliminary report on feasibility, acceptability, reliability, and validity in relation to ARFID.

The individual environment, not the family is the most important influence on preferences for common non-alcoholic beverages in adolescence.

Beverage preferences are an important driver of consumption, and strong liking for beverages high in energy (e.g. sugar-sweetened beverages [SSBs]) and dislike for beverages low in energy (e.

Prevention of neonatal late-onset sepsis: a randomised controlled trial.

Background: Late-onset sepsis (LOS), defined as sepsis occurring after 48 h of age causes substantial mortality and morbidity in very low birth weight infants. Risk factors for LOS include immaturity, intravascular catheters, mechanical ventilation, and prolonged parenteral nutrition (PN). Little attention has been paid to studying the effects of PN administration methods.

Understanding Food Fussiness and Its Implications for Food Choice, Health, Weight and Interventions in Young Children: The Impact of Professor Jane Wardle.

Purpose Of Review: This review examines the concepts of fussy eating and food neophobia in the context of key determinants of the development of children's food preferences. We discuss the evidence for genetic versus parental and other environmental influences on the ontogeny of these behavioural traits and the implications of current knowledge for interventions that attempt to lessen the impact of these traits on children's diets. Finally, we consider whether these traits increase the risk of a child becoming obese, or alternatively, underweight and malnourished.

Food fussiness and food neophobia share a common etiology in early childhood.

Background: 'Food fussiness' (FF) is the tendency to be highly selective about which foods one is willing to eat, and emerges in early childhood; 'food neophobia' (FN) is a closely related characteristic but specifically refers to rejection of unfamiliar food. These behaviors are associated, but the extent to which their etiological architecture overlaps is unknown. The objective of this study was to quantify the relative contribution of genetic and environmental influences to variation in FF and FN in early childhood; and to establish the extent to which they share common genetic and environmental influences.

Genetic and environmental influences on food preferences in adolescence.

Background: Food preferences vary substantially among adults and children. Twin studies have established that genes and aspects of the shared family environment both play important roles in shaping children's food preferences. The transition from childhood to adulthood is characterized by large gains in independence, but the relative influences of genes and the environment on food preferences in late adolescence are unknown.

Nature and Nurture in Early Feeding Behavior.

Obesity has reached epidemic proportions and research into its prevention is increasingly focusing on the earliest stages of life. Avidity of appetite has been linked to a higher risk of obesity, but studies in infancy were scarce. The Gemini twin cohort was established to investigate genetic and environmental determinants of weight trajectories in early childhood with a focus on appetite and the home environment.

Repair of congenital diaphragmatic hernia during extracorporeal life support: experience with six neonates.

Background: The management of congenital diaphragmatic hernia (CDH) in neonates has evolved considerably over the last three decades. Initial stabilization followed by surgical repair is the current standard of care. A subset fails to achieve adequate oxygenation with medical management, including the use of high frequency oscillation and inhaled nitric oxide.

Common genetic architecture underlying young children's food fussiness and liking for vegetables and fruit.

Background: Food fussiness (FF) is common in early childhood and is often associated with the rejection of nutrient-dense foods such as vegetables and fruit. FF and liking for vegetables and fruit are likely all heritable phenotypes; the genetic influence underlying FF may explain the observed genetic influence on liking for vegetables and fruit. Twin analyses make it possible to get a broad-based estimate of the extent of the shared genetic influence that underlies these traits.

The relationship between appetite and food preferences in British and Australian children.

Background: Appetitive traits and food preferences are key determinants of children's eating patterns but it is unclear how these behaviours relate to one another. This study explores relationships between appetitive traits and preferences for fruits and vegetables, and energy dense, nutrient poor (noncore) foods in two distinct samples of Australian and British preschool children.

Methods: This study reports secondary analyses of data from families participating in the British GEMINI cohort study (n = 1044) and the control arm of the Australian NOURISH RCT (n = 167).

An exploratory trial of parental advice for increasing vegetable acceptance in infancy.

Research suggests that repeatedly offering infants a variety of vegetables during weaning increases vegetable intake and liking. The effect may extend to novel foods. The present study aimed to investigate the impact of advising parents to introduce a variety of single vegetables as first foods on infants' subsequent acceptance of a novel vegetable.

Nature and nurture in children's food preferences.

Background: Health professionals identify food provision in the home as a key influence on children's food preferences. In contrast, parents often perceive children's food preferences to be inborn. One explanation for this discrepancy could be that environmental and genetic influences vary by food type.

Could the Food Neophobia Scale be adapted to pregnant women? A confirmatory factor analysis in a Portuguese sample.

Background: The Food Neophobia Scale (FNS) is widely used in different countries, however appropriate psychometric analyses are required to allow cross-cultural comparisons. To our knowledge, most studies have been conducted among children and adult populations, with no reference to pregnant women. The objective of this study was to translate and test the psychometric properties of a Portuguese version of the FNS, and to identify clusters of food neophobia during pregnancy.

Parent-administered exposure to increase children's vegetable acceptance: a randomized controlled trial.

Background: Repeated taste exposure, in combination with small rewards, has been shown to increase children's acceptance of disliked foods. However, previous studies have used direct contact with researchers or professionals for the implementation of the repeated exposure procedure. If mailed taste exposure instructions to parents produced comparable outcomes, this could be a cost-effective and easily disseminable strategy to promote healthier diets in children.

Healthy feeding habits: efficacy results from a cluster-randomized, controlled exploratory trial of a novel, habit-based intervention with parents.

Background: As dietary gatekeepers for young children, parents are often the proximal target of family-based dietary interventions. Habit theory offers a novel approach to modifying parental feeding, based on "context-dependent repetition" to promote automatic responding and to reduce decisional conflict.

Objective: This exploratory trial evaluated an intervention promoting habit formation for 3 parental feeding behaviors: serving fruit/vegetables, serving healthy snacks, and serving nonsweetened drinks.

Methodological development of an exploratory randomised controlled trial of an early years' nutrition intervention: the CHERRY programme (Choosing Healthy Eating when Really Young).

Good nutrition in the early years of life is vitally important for a child's development, growth and health. Children's diets in the United Kingdom are known to be poor, particularly among socially disadvantaged groups, and there is a need for timely and appropriate interventions that support parents to improve the diets of young children. The Medical Research Council has highlighted the importance of conducting developmental and exploratory research prior to undertaking full-scale trials to evaluate complex interventions, but have provided very limited detailed guidance on the conduct of these initial phases of research.

Parents' misperceptions of social norms for pre-school children's snacking behaviour.

Objective: Misperception of social norms may result in normalising unhealthy behaviours. The present study tested the hypothesis that parents overestimate both the frequency of unhealthy snacking in pre-school children other than their own (descriptive norms) and its acceptability to other parents (injunctive norms).

Design: A cross-sectional, self-report community survey.

Increasing food acceptance in the home setting: a randomized controlled trial of parent-administered taste exposure with incentives.

Background: The use of rewards to encourage children to eat healthily is controversial. However, researcher-led interventions have shown that incentives combined with taste exposure can increase both intake and liking. To date, this has not been tested in the home setting.

Rewards can be used effectively with repeated exposure to increase liking of vegetables in 4-6-year-old children.

Objective: To examine whether parents offering a sticker reward to their child to taste a vegetable the child does not currently consume is associated with improvements in children's liking and consumption of the vegetable.

Design: A randomized controlled trial evaluated the effectiveness of exposure only (EO) and exposure plus reward (E + R), relative to a control group, on children's liking and consumption of a target vegetable. Assessments were conducted at baseline and 2 weeks from baseline (post-intervention).

Facilitating or undermining? The effect of reward on food acceptance. A narrative review.

Using rewards in child feeding is commonplace and viewed as effective by parents, although some express concern about using 'bribery'. Psychological and economic theorists emphasize the beneficial effects of rewards in enhancing performance, although, there is evidence that the offer of rewards undermines intrinsic motivation and decreases enjoyment of the rewarded task. In the food domain, results have been mixed, but this may be explained, at least partly in terms of the measured outcome (liking vs intake) and the initial level of motivation towards the target foods (liked vs disliked).

Characteristics of family mealtimes affecting children's vegetable consumption and liking.

Research has documented an association between family mealtimes and higher dietary quality in school-aged children and adolescents. However, there is little understanding of the specific characteristics of mealtimes that are beneficial and a lack of research with preschool-aged children. This cross-sectional study conducted in the United Kingdom in 2008 examined associations between mealtime characteristics and preschoolers' vegetable consumption and liking.
