Strategies used by parents to restrict children's access to highly palatable but unhealthy foods have been described collectively as restrictive feeding practices. Ironically, evidence shows these practices may foster maladaptive eating behaviours and increase children's risk of obesity. This systematic review and series of meta-analyses aim to est...

Objective Explore the nature and dimensions of restrictive feeding with mothers of 6-year-olds. Design Semistructured interviews with mothers. Conversations were audio-recorded and transcribed verbatim. Setting Brisbane and Adelaide, Australia. Participants Twenty-nine mothers of 6-year-olds. Phenomenon of Interest Mothers’ restrictive feeding...

To compare feeding practices within mother–father dyads and explore whether outcomes of an efficacious intervention for mothers generalised to fathers’ feeding practices. The NOURISH RCT evaluated an early feeding intervention that promoted positive feeding practices to support development of healthy eating habits and growth. The intervention was d...

Objective To examine longitudinal patterns of child introduction to foods and drinks targeted for restriction by parents and associations between child intake frequency, mother’s own liking, child early exposure and child liking for restricted foods and drinks at 5 years old. Design The study involved secondary analyses of longitudinal data from m...

Background The nexus between appetitive traits, dietary patterns and weight status has predominantly been studied in a mixed sample (healthy weight, overweight and obese sample). Aim This cross-sectional study examined associations between overweight/obese children’s appetitive traits, dietary patterns and weight status. Methods We studied childr...

Both genetic and environmental influences underpin complex multidimensional associations between maternal and child eating behaviours, maternal feeding practices and child obesity risk. The aim of the present study was to explore cross-sectional relationships between maternal and child eating behaviours, and to examine whether maternal feeding prac...

Abstract Background Women who enter pregnancy overweight or obese tend to have poorer breastfeeding outcomes compared to non-overweight women. Women’s experiences of specific breastfeeding-related problems and reasons for use of formula have not been systematically investigated according to pre-pregnancy BMI. The aim of this study was to compare se...

Objective: To examine the role of parent concern in explaining nonresponsive feeding practices in response to child fussy eating in socioeconomically disadvantaged families. Design: Mediation analysis of cross-sectional survey data. Setting: Socioeconomically disadvantaged urban community in Queensland, Australia. Participants: Cohabiting mo...

Objective: Child fussy eating has been associated with a range of maternal feeding practices; however, whether effects are parent-driven, child-driven, or bidirectional (i.e., both) remains unclear. This study tested for bidirectional relationships between nonresponsive and structure-related maternal feeding practices and child fussy eating at age...

Objective: Few studies on child feeding have focused on family dynamics or disadvantaged families, yet feeding occurs in the complex social, economic, and relational context of the family. We examined how the level (high vs low) and concordance (concordant vs discordant) of nonresponsive feeding practices of mothers and fathers are associated with...

Background This study examined bidirectional relationships between maternal feeding practices and child food responsiveness and satiety responsiveness from 2 to 5 years. Methods Mothers (N = 207) reported their own feeding practices and child eating behaviours using validated questionnaires at child ages 2, 3.7, and 5 years. Cross-lagged analyses w...

Background The aims of this study were to evaluate the factor structure of the newly developed Adult Eating Behaviour Questionnaire (AEBQ) (Hunot et al., Appetite 105:356-63, 2016) in an Australian sample, and examine associations between the four food approach and four food avoidance appetitive traits with body mass index (BMI). Methods Participa...

Objective: Determine whether feeding practices across mothers and fathers are interpreted and measured with equivalent accuracy (measurement invariance) using the Feeding Practices and Structure Questionnaire-28 (FPSQ-28) Design: Cross-sectional hard-copy and online survey design Setting: Socioeconomically disadvantaged community in Queensland, Au...

Objective: Women with a higher BMI are at increased risk of breastfeeding for a shorter duration, however it is unclear if weight status itself or other factors such as feeding intentions are responsible for early breastfeeding cessation. The aim of this study was determine the influence of maternal pre-pregnancy weight status on infant feeding in...

Objectives Little is known about the antecedents to dietary and physical activity behaviours that can support healthy gestational weight gain (GWG) across different weight status groups in pregnancy. The aim of this study was to use constructs common to dominant health behaviour theories to determine if predisposing, reinforcing and enabling factor...

Background: Excess gestational weight gain (GWG) contributes to long-term obesity in mothers and children. To guide the tailoring of interventions to prevent excess GWG, a better understanding is needed of the lifestyle-related health cognitions that influence women's attempts to manage GWG. Objective: To examine the relationship between health...

Objective To identify associations between structure-related and non-responsive feeding practices and children's eating behaviors. Design Cross-sectional online survey design. Participants Parents (n = 413) of 1- to 10-year-old children. Main Outcome Measures Parental feeding practices and child eating behaviors were measured via the validated...

Background Parental feeding practices are thought to play a causal role in shaping a child’s fussiness; however, a child-responsive model suggests that feeding practices may develop in response to a child’s emerging appetitive characteristics. We used a novel twin study design to test the hypothesis that mothers vary their feeding practices for twi...

Objective: To evaluate dietary intake impact outcomes up to 3.5 years after the NOURISH early feeding intervention (concealed allocation, assessor masked randomized controlled trial). Methods: In this study, 698 first-time mothers with healthy term infants were allocated to receive anticipatory guidance on protective feeding practices or usual c...

Parental feeding practices and children's eating behaviours are inter-related and both have been implicated in the development of childhood obesity. However, research on the parent-child feeding relationship during the first few months of life is limited. The aim of this study was to examine the cross-sectional relationship between maternal feeding...

Prospective studies and intervention evaluations that examine change over time assume that measurement tools measure the same construct at each occasion. In the area of parent-child feeding practices, longitudinal measurement properties of the questionnaires used are rarely verified. To ascertain that measured change in feeding practices reflects t...

Background: Longer breastfeeding duration appears to have a protective effect against childhood obesity. This effect may be partially mediated by maternal feeding practices during the first years of life. However, the few studies that have examined links between breastfeeding duration and subsequent feeding practices have yielded conflicting resul...

Food neophobia, the rejection of unknown or novel foods, may result in poor dietary patterns. This study investigates the cross-sectional relationship between neophobia in children aged 24 months and variety of fruit and vegetable consumption, intake of discretionary foods and weight. Secondary analysis of data from 330 parents of children enrolled...

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 Austral...

We examined whether exposure to a greater number of fruits, vegetables, and noncore foods (ie, nutrient poor and high in saturated fats, added sugars, or added salt) at age 14 months was related to children's preference for and intake of these foods as well as maternal-reported food fussiness and measured child weight status at age 3.7 years. This...

Background Feeding practices are commonly examined as potentially modifiable determinants of children’s eating behaviours and weight status. Although a variety of questionnaires exist to assess different feeding aspects, many lack thorough reliability and validity testing. The Feeding Practices and Structure Questionnaire (FPSQ) is a tool designed...

To evaluate the evidence for association between obesity risk outcomes >12 months of age and timing of solid introduction in healthy term infants in developed countries, the large majority of whom are not exclusively breastfed to six months of age. Studies included were published 1990 to March 2013. Twenty-six papers with weight status or obesity p...

This study aimed to examine whether pre-pregnancy weight status was associated with maternal feeding beliefs and practices in the early post-partum period. This study uses secondary analysis of longitudinal data from Australian mothers. Participants (n = 486) were divided into two weight status groups based on self-reported pre-pregnancy weight and...

This cross-sectional study examined the association between controlling feeding practices and children's appetite traits. The secondary aim studied the relationship between controlling feeding practices and two proxy indicators of diet quality. Participants were 203 Australian-Indian mothers with children aged 1–5 years. Controlling feeding practic...

AimChild-feeding practices may be modifiable risk factors for childhood obesity; however, investigation of feeding practices in non-Western populations is scarce. This cross-sectional study examines the feeding practices of affluent Indian mothers with children aged one to five years residing in Australia and Mumbai, India. The secondary aim was to...

Both facial cues of group membership (race, age, and sex) and emotional expressions can elicit implicit evaluations to guide subsequent social behavior. There is, however, little research addressing whether group membership cues or emotional expressions are more influential in the formation of implicit evaluations of faces when both cues are simult...

Food neophobia is a highly heritable trait characterized by the rejection of foods that are novel or unknown and potentially limits dietary variety, with lower intake and preference particularly for fruits and vegetables. Understanding non-genetic (environmental) factors that may influence the expression of food neophobia is essential to improving...

The aim of this study was to evaluate the factor structure of the Baby Eating Behaviour Questionnaire (BEBQ) in an Australian community sample of mother-infant dyads. A secondary aim was to explore the relationship between the BEBQ subscales and infant gender, weight and current feeding mode. Confirmatory factor analysis (CFA) utilising structural...

Background Early feeding practices lay the foundation for children’s eating habits and weight gain. Questionnaires are available to assess parental feeding but overlapping and inconsistent items, subscales and terminology limit conceptual clarity and between study comparisons. Our aim was to consolidate a range of existing items into a parsimonious...

The study examined the accuracy of maternal-perceived child weight. Urban affluent mothers of 111 children aged 2-5 years were recruited. Nearly a quarter of mothers overestimated their underweight child as normal weight and all overweight/obese children were perceived as normal weight. Mothers, therefore, were unable to recognize their child's tru...

Objective: The objective was to describe parent-reported child eating behavior and maternal parenting impact outcomes of an infant feeding intervention to reduce child obesity risk. Methods: An assessor masked Randomized Controlled Trial (RCT) with concealed allocation of individual mother-infant dyads. The NOURISH RCT enrolled 698 first-time mo...

Maternal depression is a known risk factor for poor outcomes for children. Pathways to these poor outcomes relate to reduced maternal responsiveness or sensitivity to the child. Impaired responsiveness potentially impacts the feeding relationship and thus may be a risk factor for inappropriate feeding practices. The aim of this study was to examine...

The Food and Nutrition stream of Australasian Child and Adolescent Obesity Research Network (ACAORN) aims to improve the quality of dietary methodologies and the reporting of dietary intake within Australasian child obesity research (http://www.acaorn.org.au/streams/nutrition/). With 2012 marking ACAORN's 10th anniversary, this commentary profiles...

Maternal perceptions and practices regarding child feeding have been extensively studied in the context of childhood overweight and obesity. To date, there is scant evidence on the role of fathers in child feeding. This cross-sectional study aimed to identify whether characteristics of fathers and their concerns about their children’s risk of overw...

Aim: This cross-sectional study explores associations between migrant Indian mothers' use of controlling feeding practices (pressure to eat, restriction and monitoring) and their concerns and perceptions regarding their children's weight and picky eating behaviour. Methods: A total of 230 mothers with children aged 1-5 years, residing in Australia...

Facial cues of racial outgroup or anger mediate fear learning that is resistant to extinction. Whether this resistance is potentiated if fear is conditioned to angry, other race faces has not been established. Two groups of Caucasian participants were conditioned with two happy and two angry face conditional stimuli (CSs). During acquisition, one h...

Researchers over the last decade have documented the association between general parenting style and numerous factors related to childhood obesity (e.g., children’s eating behaviors, physical activity, and weight status). Many recent childhood obesity prevention programs are family focused and designed to modify parenting behaviors thought to contr...

The role of fathers in shaping their child's eating behaviour and weight status through their involvement in child feeding has rarely been studied. This study aims to describe fathers' perceived responsibility for child feeding, and to identify predictors of how frequently fathers eat meals with their child. Four hundred and thirty-six Australian f...

Objective: The goal of this study was to evaluate outcomes of a universal intervention to promote protective feeding practices that commenced in infancy and aimed to prevent childhood obesity. Methods: The NOURISH randomized controlled trial enrolled 698 first-time mothers (mean ± SD age: 30.1 ± 5.3 years) with healthy term infants (51% female)...

The preparedness theory of classical conditioning proposed by Seligman (1970, 1971) has been applied extensively over the past 40 years to explain the nature and "source" of human fear and phobias. In this review we examine the formative studies that tested the four defining characteristics of prepared learning with animal fear-relevant stimuli (ty...

Despite important implications for the budgets, statistical power and generalisability of research findings, detailed reports of recruitment and retention in randomised controlled trials (RCTs) are rare. The NOURISH RCT evaluated a community-based intervention for first-time mothers that promoted protective infant feeding practices as a primary pre...

The purpose of this study was to investigate the association between temperament in Australian infants aged 2-7months and feeding practices of their first-time mothers (n=698). Associations between feeding practices and beliefs (Infant Feeding Questionnaire) and infant temperament (easy-difficult continuous scale from the Short Temperament Scale fo...

Food preferences have been identified as a key determinant of children's food acceptance and consumption. The aim of this study was to identify factors that influence children's liking for fruits, vegetables and non-core foods. Participants were Australian mothers (median age at delivery=31years, 18-46years) and their two-year-old children (M=24mon...

Objective: To evaluate a universal obesity prevention intervention, which commenced at infant age 4-6 months, using outcome data assessed 6 months after completion of the first of two intervention modules and 9 months from baseline. Design: Randomised controlled trial of a community-based early feeding intervention. Subjects and methods: Six h...

The question as to whether poser race affects the happy categorization advantage, the faster categorization of happy than of negative emotional expressions, has been answered inconsistently. Hugenberg (2005) found the happy categorization advantage only for own race faces whereas faster categorization of angry expressions was evident for other race...

Introduction: Studies show that in 3-11 year-olds, parental feeding style is directly associated with child weight [1] and also moderates the association between feeding practices and weight [2]. This cross-sectional study aimed to examine these relationships in younger children. Methods: Data from 331 of 698 first-time mothers of healthy term chi...

The present study used ERPs to compare processing of fear-relevant (FR) animals (snakes and spiders) and non-fear-relevant (NFR) animals similar in appearance (worms and beetles). EEG was recorded from 18 undergraduate participants (10 females) as they completed two animal-viewing tasks that required simple categorization decisions. Participants we...

Empathy is an important pro-social behaviour critical to a positive client-therapist relationship. Therapist anxiety has been linked to reduced ability to empathise and lower client satisfaction with therapy. However, the nature of the relationship between anxiety and empathy is currently unclear. The current study investigated the effect of experi...

The present study investigated whether, like fear conditioned to pictures of snakes and spiders, fear conditioned to angry faces resists extinction even after verbal instruction and removal of the shock electrode. Participants were trained in a differential Pavlovian fear conditioning procedure with angry face or happy face conditional stimuli (CSs...

The acquisition and extinction of affective valence to neutral geometrical shape conditional stimuli was investigated in three experiments. Experiment 1 employed a differential conditioning procedure with aversive shock USs. Differential electrodermal responding was evident during acquisition and lost during extinction. As indexed by verbal ratings...

The eye-blink startle reflex can be modulated by attentional and emotional processes. The reflex is facilitated during stimuli that engage attention. A linear pattern of emotional modulation has also been consistently demonstrated: the reflex is facilitated during unpleasant stimuli and attenuated during pleasant stimuli. However, during anticipati...

Earlier research found evidence for electro-cortical race bias towards black target faces in white American participants irrespective of the task relevance of race. The present study investigated whether an implicit race bias generalizes across cultural contexts and racial in- and out-groups. An Australian sample of 56 Chinese and Caucasian males a...

The present study investigated whether facial expressions of emotion presented outside consciousness awareness will elicit evaluative responses as assessed in affective priming. Participants were asked to evaluate pleasant and unpleasant target words that were preceded by masked or unmasked schematic (Experiment 1) or photographic faces (Experiment...

Previous research has shown resistance to extinction of fear conditioned to racial out-group faces, suggesting that these stimuli may be subject to prepared fear learning. The current study replicated and extended previous research by using a different racial out-group, and testing the prediction that prepared fear learning is unaffected by verbal...

The current research assessed the effects of verbal instruction on affective and expectancy learning during repeated contingency reversals (Experiment 1) and during extinction (Experiment 2) in a picture-picture paradigm. Affective and expectancy learning displayed contingency reversal and extinction, but changes were slower for affective learning....

The interactive effects of emotion and attention on attentional startle modulation were investigated in two experiments. Participants performed a discrimination and counting task with two visual stimuli during which acoustic eyeblink startle-eliciting probes were presented at long lead intervals. In Experiment 1, this task was combined with aversiv...

Affect modulates the blink startle reflex in the picture-viewing paradigm, however, the process responsible for reflex modulation during conditional stimuli (CSs) that have acquired valence through affective conditioning remains unclear. In Experiment 1, neutral shapes (CSs) and valenced or neutral pictures (USs) were paired in a forward (CS-->US)...

Abstract Emotional processes modulate the size of the eyeblink startle reflex in a picture-viewing paradigm, but it is unclear whether emotional processes are responsible for blink modulation in human conditioning. Experiment 1 involved an aversive differential conditioning phase followed by an extinction phase in which acoustic startle probes were...

Affective learning, the acquisition of likes and dislikes, was investigated in two experiments using verbal ratings and affective priming as indices of affective change. In both experiments, neutral geometric shapes were paired with pleasant or unpleasant pictures in a picture-picture conditioning procedure to acquire positive and negative valence....

Affective learning is a process by which likes and dislikes are formed through an association learned between a neutral stimulus (conditional stimulus; CS) and an affective stimulus (unconditional stimulus; US). This thesis presents an investigation of affective learning of positive valence. The acquisition of positive valence was assessed to furth...
