Behavioral outcomes of picky eating in childhood: a prospective study in the general population

Risk Factors and Consequences of Food Neophobia and Pickiness in Children and Adolescents: A Systematic Review

Food neophobia and pickiness are the resistance or refusal to eat and/or avoid trying new foods due to a strong reaction of fear towards the food or an entire group of foods. This systematic review aims to assess evidence on the risk factors and effects of food neophobia and picky eating in children and adolescents, giving elements to avoid the lack of some foods that can cause nutritional deficiencies, leading to future pathologies when they are adults. A systematic literature search was performed in Medlars Online International Literature (MEDLINE) via Pubmed and EBSCOhost, LILACS and IBECS via Virtual Health Library (VHL), Scopus, and Google Scholar. MeSH terms used were: ((food neophobia [Title/Abstract]) OR (picky eating [Title/Abstract]) OR (food selectivity [Title/Abstract])) NOT ((anorexia nervosa [MeSH Terms]) OR (bariatric surgery [MeSH Terms]) OR (avoidant restrictive food intake disorder [MeSH Terms]) OR (autism spectrum disorder [MeSH Terms])). One hundred and forty-two (n = 142) articles were selected for children and adolescents (0-18 years old). They were structured according to contents: prevalence, risk factors, consequences, strategies and treatment. The studies showed a prevalence of the need for intervention on modifiable risk factors. Food neophobia and pickiness developed in childhood are conditioned by risk factors related to biological, social, and environmental characteristics, as well as family education and skills. Strategies to minimize or avoid these disorders should be aimed at implementing healthy habits at these levels.

Long-term implications of a multidisciplinary tube-weaning program: Parental perspectives

Objectives

Children who are unable to eat and drink orally require temporary or permanent enteral nutritional support via tube feeding. The objective was to describe a weaning program held at a children's rehabilitation hospital and to review the long-term outcomes of the transition from tube nutrition to oral feeding.

Methods

The parents of 82 children who took part in the ALYN intervention program from 2011 to 2022 were requested to participate in a telephone survey to learn about their child's status related to eating, education, social wellbeing, and overall health. They also provided feedback concerning their experience with the tube-weaning program and their current reliance on support for eating-related issues.

Results

The parents of 35 (39%) children responded. Their mean ± SD age at the time of treatment were 2.1 ± 1.76, and the mean ± SD age at the time of the survey 8.85 ± 3.96 years. Their mean current zBMI is -0.7. Overall, parents were very satisfied with the child's eating (4.7 out of 5) ± 0.7, and few reported that the child's eating affected the family mealtime routine (2.1 out of 5) ± 1.3. The children's age at weaning was significantly correlated with parental reports of concern with the child's current eating ability, with younger ages at weaning associated with lower parental concern.

Conclusions

The data demonstrated that despite the complexity of the participants, most children succeed in achieving long-term independent eating, good nutritional status, and social participation around mealtimes.

Impact of parent child interaction therapy on child eating behaviors

BACKGROUND

Picky eating commonly co-occurs with disruptive behaviors in young children. While feeding interventions exist, it remains unknown whether unmodified behavioral parent training (BPT) improves maladaptive child eating. As coercive feeding practices may exacerbate picky eating, BPT could ameliorate associated behaviors by increasing authoritative parenting.

METHODS

Caregiver-child dyads (N = 194, ages 2-8) received 18 weeks of Parent-Child Interaction Therapy (PCIT). Caregivers completed the Behavioral Pediatrics Feeding Assessment Scale (BPFAS) at pre-, mid-, and post-treatment. The BPFAS overall picky eating frequency and number of problems was examined, as well as the subscale of mealtime misbehaviors, and overall caregiver feeding practices.

RESULTS

From pre-to post-treatment, reductions occurred in frequency/problems scales across overall BPFAS child behaviors. Mealtime misbehaviors significantly declined at all checkpoints - early skill acquisition may drive this early change, whereas changes in frequency/problem scales occurred after mid-treatment, suggesting later skill acquisition may be driving these changes. On the coercive caregiver feeding subscale, multivariate regression identified a significant race by time interaction (p = .02) - multiracial caregivers improved while others showed no difference.

CONCLUSION

Standard PCIT, not adapted for feeding concerns, decreased maladaptive child eating behaviors across all caregivers and coercive feeding practices in multiracial caregivers. Authoritative parenting principles may generalize to eating contexts for certain cultural groups. PCIT shows promise as an early upstream intervention potentially changing trajectories without needed feeding content modifications. Assessment of long-term maintenance is warranted. Coupling with nutrition education could optimize impact.

Feeding-Related Early Signs of Autism Spectrum Disorder: A Narrative Review

Feeding difficulties are prevalent among individuals with autism spectrum disorder (ASD). Nevertheless, the knowledge about the association between feeding-related early signs and child development remains limited. This review aimed to describe the signs and symptoms related to feeding during child development and to explore their relevance to the diagnosis of ASD. Specialists in nutrition and/or ASD conducted a search of MEDLINE, PsycINFO, and Web of Science databases. Although studies in typically developing children demonstrate age-related variations in hunger and satiety cues, the literature about early feeding indicators in ASD is scarce. Challenges such as shortened breastfeeding duration, difficulties in introducing solid foods, and atypical mealtime behaviors are frequently observed in children with ASD. The eating difficulties experienced during childhood raise concerns for caregivers who base their feeding practices on their perceptions of food acceptance or refusal. Considering the observed associations between feeding difficulties and ASD, the importance of recognizing feeding-related signs according to developmental milestones is emphasized to alert medical professionals that deviation in the formation of feeding habits and skills could indicate the need for ASD diagnostic investigation.

Age-dependent normal values for the 'Infant Gastroesophageal Reflux Questionnaire Revised'

The Infant Gastroesophageal Reflux Questionnaire Revised (I-GERQ-R) is used to score and evaluate gastroesophageal reflux (GER) related symptoms such as regurgitation, irritability and crying. A cut-off of ≥ 16 has been suggested to discriminate between GER and GER-disease. However, age-specific normal values were not assessed. Aim of this study was to determine age-specific normal values in healthy infants. Cross-sectional survey in healthy infants aged 0-24 months during their regular check-ups at well-baby clinics and through an online questionnaire using the I-GERQ-R. Infants with a history of (suspected) GER-disease were excluded. Spearman's correlation coefficient was calculated to explore age-related trends. A total of 979 healthy infants (47% male, median age 6 [0-24] months) were included. Median I-GERQ-R score, regardless of age, was 6 (range: 0-27). I-GERQ-R scores significantly decreased with age (rs = -0.569, p < 0.001). Of all infants, 49 (5%) had a score of ≥ 16 which previously has been considered 'suggestive of GER-disease'. Scores of ≥ 16 were most frequently seen in newborns aged 0-4 months (16% in 0-1 months to 4% in 3-4 months) and disappeared after the age of 16 months. High scores in the first months of life were caused by a high prevalence of regurgitation, colic-associated symptoms and hiccup frequency.  Conclusion: Age-dependent normal values for the I-GERQ-R show that reflux symptoms decrease in the first 24 months of life in healthy infants. Scores of ≥ 16 should not necessarily be considered abnormal in young infants. Validation as a diagnostic tool for GER-disease using age-appropriate normal values is needed. What is Known: • The Infant Gastro Esophageal Reflux Questionnaire Revised (I-GERQ-R) was developed to objectively score and evaluate GER-related symptoms in infants. • Previously a cut off of ≥ 16 has been suggested to differentiate between gastro esophageal reflux (GER) and GER-disease. What is New: • We present age-specific normal values of the I-GERQ-R in healthy infants. • I-GERQ-R scores clearly decrease with age and up to 16% of young healthy infants have a score that is above the previously suggested cut-off score of 16 for GER-disease.

Complementary Feeding Methods, Feeding Problems, Food Neophobia, and Picky Eating among Polish Children

Proper nutrition during the first period of life is primarily related to meeting energy needs and providing essential nutrients that ensure the infant's normal physical and psychomotor development. Improper nutrition during this period, inadequate amounts of nutrients, inappropriate timing and manner of introduction of individual foods, can permanently alter metabolism and the course of physiological processes, increasing the risk of diseases such as obesity, allergic diseases, and cardiovascular diseases. This study aimed to verify how the method of complementary feeding influences the occurrence of food neophobia between 2 and 7 years of age, as well as to assess the different nutritional aspects resulting from the process of starting feeding other than breast milk and milk formula. In this study, 490 mothers and their children aged 2-7 years participated. The research tool was a questionnaire consisting of a child's dietary assessment and standardized questionnaires assessing food neophobia among children: Food Neophobia Scale for Children (FNSC) and the Montreal Children's Hospital-Pediatric Feeding (MCH-FS). In the study group of children, 238 (48.57%) had no Baby-Led Weaning Method (no BLW) method used during complementary feeding (CF), and 252 (51.42%) children used Baby-Led Weaning Method (BLW). According to the FNSC questionnaire, a high risk of food neophobia was found in 32.65% of the children studied and a medium risk in 39.80%. The medium risk of feeding problem occured in 11.63% of children, the high risk in 6.73% of children, and the highest risk in 6.94% (MCH-FS). No statistically significant differences were observed between the BLW and NoBLW groups. High risk of food neophobia occured in 1/3 of the children studied, but there was no relationship in the study group between the mode of CF (BLW/NoBLW) and the risk of food neophobia.

Effect of being a persistent picky eater on feeding difficulties in school-aged children

Children who are picky eaters often develop feeding difficulties during preschool years. These difficulties may persist into adolescence in some children. The study aim was to examine feeding difficulties and maternal feeding strategies longitudinally from age 5.5-8.5 years in relation to persistent picky eating. Picky eating behaviour in children enrolled in the Avon Longitudinal Study of Parents and Children was assessed using questionnaires between 2 and 5.5 years of age. Feeding behaviours were evaluated using questionnaires between 5.5 and 8.5 years. Data were analysed using adjusted logistic regression models. Of the 7405 children with data on picky eating 1926 (26%) were classified as never picky eaters, 385 (5%) were non-persistent picky eaters and 564 (8%) were persistent picky eaters. At 5.5, 7 and 8.5 years both persistent picky eaters and non-persistent picky eaters were more likely than never picky eaters to indicate difficulties in eating what the mother wanted, deliberately eat insufficiently, refuse to eat what was on offer, be choosy, not over-eat, and be difficult to get into routine, but with the likelihood decreasing with age (e.g. in persistent picky eaters vs non-picky eaters: refused to eat offered food OR 44.2 (95% CI 29.1, 67.0) at 5.5 years, 15.5 (11.5, 20.8) at 7 years and 14.1 (10.7, 18.6) at 8.5 years). The families of children who are picky eaters at the time of entering the school system should be offered reassurance that the feeding difficulties are likely to slowly resolve over time.

Eating behavior-mediated association between attention deficit hyperactivity disorder and body fat mass

Background

Adverse eating behaviors and a high rate of obesity have been identified among children diagnosed with attention deficit hyperactivity disorder (ADHD). In this study, we investigate the relationships between eating behaviors and body fat mass among children with ADHD.

Methods

All participants were recruited from the Children's Health Care Department of the Children's Hospital of Nanjing Medical University from June 2019 to June 2020. ADHD was diagnosed according to the diagnostic criteria of the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) by psychiatrists. Core ADHD symptoms defined by the DSM-5 were inattention and hyperactivity/impulsivity. The anthropomorphic indices defined by the World Health Organization (WHO) were utilized in this study (body mass index [BMI], underweight, normal body mass, overweight, obesity, short stature). Body fat mass, fat mass percentage (FM%), skeletal muscle mass, skeletal muscle mass percentage (SMM%) were tested via body composition meter, and eating behaviors were assessed by parents using the Chinese version of the Children's Eating Behavior Questionnaire (CEBQ). The CEBQ was comprised of subscales related to food avoidant behaviors (satiety responsiveness, slowness in eating, fussiness, and emotional undereating) and food approach behaviors (food responsiveness, enjoyment of Food, desire to drink, and emotional overeating). The associations among ADHD, obesity and adverse eating behavior were tested through correlation analysis, and a mediating effect model was established to explore the effect of eating behaviors.

Results

A total of 548 participants aged 4-12 years were recruited. Among them, 396 were diagnosed with ADHD, with the remaining 152 enrolled in a control group. Compared with the control group, the ADHD group had higher incidences of overweight (22.5% vs. 14.5%) and obesity (13.4% vs. 8.6%) (p < 0.05). The ADHD group was more likely to display "slowness in eating" (11.01 ± 3.32 vs. 9.74 ± 2.95), "fussiness" (15.61 ± 3.54 vs. 15.03 ± 2.84), "food responsiveness" (11.96 ± 4.81 vs. 9.88 ± 3.71) and "desire to drink" (8.34 ± 3.46 vs. 6.58 ± 2.72) (p < 0.05). Moreover, The FM% of children with ADHD was positively correlated with inattention (β = 0.336, 95% CI: 0.001 to 0.673) and "food responsiveness" (β = 0.509, 95% CI: 0.352 to 0.665) in the multiple linear regression model. The mediation effect model showed that "food responsiveness" accounted for a significant portion (64.2%) of the mediating effect.

Conclusion

Children with ADHD had higher prevalence of overweight and obesity. As an important risk factor, food responsiveness may connect core symptoms of ADHD with obesity.

Psychosocial, Medical, and Demographic Variables Associated with Parent Mealtime Behavior in Young Children Recently Diagnosed with Type 1 Diabetes

OBJECTIVE

Managing young children's mealtime concerns can be challenging after type 1 diabetes (T1D) diagnosis because of developmental factors and diabetes management demands. To identify potential intervention targets, we evaluated medical, psychosocial, and demographic factors in relation to parents' engagement in problem mealtime behaviors (e.g., pressure to eat, restriction).

METHOD

Parents (N = 157) of young children (age 1-6 years) reported on psychosocial variables (parent fear of hypoglycemia, family functioning, parent problem solving, and parents' problem mealtime behavior frequency and perceptions of being problematic) within 2 months after T1D diagnosis. Hierarchical regression analyses examined associations among psychosocial variables, demographics (child sex, parent race/ethnicity), child continuous glucose monitor (CGM) use, and parents' problem mealtime behaviors.

RESULTS

Parents of children using CGMs reported parents' mealtime behaviors as more problematic than nonusers, but there were no differences for other medical or demographic variables. Models predicting parents' problem mealtime behavior frequency and problem perceptions that included psychosocial variables, demographic variables, and CGM use led to significant R 2 of 0.14 and 0.16, respectively. CGM use and parent problem solving were significantly associated with parent mealtime behaviors being perceived as more problematic.

CONCLUSION

Shortly after T1D diagnosis in young children, medical and parent psychosocial factors related to how frequently parents engaged in problem mealtime behaviors and the degree to which parents perceived them as problematic. Other factors may further explain the complexities of mealtime management. Considering parents' problem-solving skills and child treatment regimens may help guide interventions targeting mealtime challenges during the new diagnosis period.

Associations of toddler mechanical/distress feeding problems with psychopathology symptoms five years later

BACKGROUND

Feeding problems are common in early childhood, and some evidence suggests that feeding problems may be associated with psychopathology. Few prospective studies have explored whether toddler feeding problems predict later psychopathology.

METHODS

Mothers of 1,136 children from the Upstate KIDS cohort study provided data when children were 2.5 and 8 years of age. Food refusal (picky eating) and mechanical/distress feeding problems and developmental delays were assessed at 2.5 years. Child eating behaviors (enjoyment of food, food fussiness, and emotional under and overeating) and child psychopathology (attention-deficit/hyperactivity (ADHD), oppositional-defiant (OD), conduct disorder (CD), and anxiety/depression) symptoms were assessed at 8 years.

RESULTS

Mechanical/distress feeding problems at age 2.5, but not food refusal problems, were associated with ADHD, problematic behavior (OD/CD), and anxiety/depression symptoms at 8 years in models adjusting for eating behaviors at 8 years and child and family covariates. Associations with mechanical/distress feeding problems were larger for ADHD and problematic behavior than anxiety/depression symptoms, though all were modest. Model estimates were similar for boys and girls.

CONCLUSIONS

Much of the research on feeding problems focuses on picky eating. This study suggests that early mechanical and mealtime distress problems may serve as better predictors of later psychopathology than food refusal. Parents and pediatricians could monitor children with mechanical/distress feeding problems for signs of developing psychopathology.

Feeding Problems as an Indicator of Developmental Delay in Early Childhood

OBJECTIVE

To determine whether feeding problems are indicators of developmental delay.

STUDY DESIGN

In this prospective longitudinal cohort study, mothers of 3597 children (49% female, 35% multiples) reported on their children's feeding problems and developmental delays (using the Ages and Stages Questionnaire [ASQ]) when children were age 18, 24, and 30 months. Average scores of feeding problems were computed at each age, as well as a categorical score indicating a persistently high number of feeding problems ≥90th percentile across time. The Battelle Developmental Inventory, Second Edition (BDI-2) was used to assess development in 5 domains for a subset of children at 4 years.

RESULTS

In adjusted analyses, feeding problems (per point increase) were increasingly associated with 6 ASQ domains from 18 months (OR, 1.30-1.98) to 24 months (OR, 2.07-2.69) to 30 months (OR, 3.90-5.64). Compared with children who never experienced feeding problems, children who experienced a high number of feeding problems at 1 or 2 time points were more than twice as likely to have a delay on all ASQ domains (OR, 2.10-2.50), and children who experienced a high number of feeding problems at all 3 time points were ≥4-fold more likely to have a delay on all ASQ domains (OR, 3.94-5.05). Children with 1-point higher feeding problems at 30 months scored 3-4 points lower in all BDI-2 domains at 4 years.

CONCLUSIONS

Frequent feeding problems, especially those that persist into the third year, could be used to identify children at risk for developmental delay for more targeted screening.

Consequences of Picky Eating in College Students

OBJECTIVE

To examine the relation between young adult picky eating (PE) and psychosocial outcomes (eg, social phobia, quality of life) and dietary intake.

DESIGN

Cross-sectional study including demographic, quantitative, and qualitative measures.

PARTICIPANTS

Midwestern undergraduate convenience sample (n = 488) recruited early 2020.

MAIN OUTCOME MEASURES

Picky eating identity and bias internalization, social phobia, quality of life, and dietary intake.

ANALYSES

Pearson correlations were conducted among study variables. Independent t tests compared picky eaters and nonpicky eaters on key variables. Qualitative data were coded using content analysis.

RESULTS

Picky eaters reported eating less fiber (t[445] = -3.51; P < 0.001; d = 0.34) and vegetables (t[464] = -3.57; P < 0.001; d = 0.33), and reported more social phobia (t[336.84] = 4.04; P < 0.001; d = 0.39) than nonpicky eaters. Picky eating behaviors were positively correlated with PE identity (r[190] = 0.48; P < 0.001; R² = 0.23) and bias internalization (r[190] = 0.44; P < 0.001; R² = 0.19).

CONCLUSIONS AND IMPLICATIONS

Future research might explore additional factors that theoretically overlap with PE behavior (eg, other eating styles, disordered eating patterns) or play a role in PE (eg, anxiety, obsessive-compulsive difficulties). A greater understanding of these factors may lead to intervention to reduce PE in adults. In addition, validation of the PE identity and PE distress measures is essential for future use and to replicate this study's findings.

Picky Eating in Children: A Scoping Review to Examine Its Intrinsic and Extrinsic Features and How They Relate to Identification

The health benefits and importance of family mealtimes have been extensively documented. Picky eating can impact this complex activity and has numerous extrinsic (or external) and intrinsic (or internal) features. Occupational therapists work with children and their families by looking at both intrinsic and extrinsic influences and are therefore well-placed to work within this context. This scoping review comprises a comprehensive search of key health industry databases using pre-determined search terms. A robust screening process took place using the authors pre-agreed inclusion and exclusion criteria. There were 80 studies that met the inclusion criteria, which were then mapped using content analysis. The most common assessments used to identify picky eating relied on parental reports and recall. Often additional assessments were included in studies to identify both the intrinsic and extrinsic features and presentation. The most common reported intrinsic features of the child who is a picky eater included increased sensitivity particularly to taste and smell and the child's personality. Extrinsic features which appear to increase the likelihood of picky eating are authoritarian parenting, rewards for eating, and pressuring the child to eat. Most commonly reported extrinsic features that decrease the likelihood of picky eating are family meals, responsive parents, and involving the child in the preparation of food. In conclusion, there is a lack of published papers addressing the role of occupational therapists in the assessment and identification of picky eating in children. There appears to be a complex interplay between intrinsic and extrinsic features which impact caregiver responses and therefore on the picky eater.

The association of adverse life events with children's emotional overeating and restrained eating in a population-based cohort

OBJECTIVE

Life adversities are recognized risk factors for eating disorders, in adolescents and adults, but whether such adversities are also associated with particular eating behaviors earlier in life is still unclear. Our aim was to assess whether experiencing adverse life events in early childhood is associated with emotional overeating and restrained eating at age 10.

METHODS

Emotional overeating and restrained eating were assessed in 4,653 10-years-old children using the mother-reported Children's Eating Behavior Questionnaire and Dutch Eating Behavior Questionnaire. Mothers also reported on 24 different life events during childhood, those with moderate or severe impact being categorized as adverse life events. Regression analyses were performed to investigate relationships between adverse life events and eating behaviors in the total sample.

RESULTS

Adjusted for covariates, adverse life events were associated with more emotional overeating and restrained eating in children (p-values for trend <.01). Specifically, mothers who reported that their child experienced 3+ adverse life events, also reported significantly higher emotional overeating (B = 0.20; 95% confidence interval [CI], 0.06-0.33) and restrained eating (B = 0.21; 95% CI, 0.08-0.33) in their children relative to children who did not experience adverse life events. These results did not differ by sex.

DISCUSSION

Our results based on mother-reported data suggest that children's experiences of life adversities are associated with emotional overeating and restrained eating at age 10 years. We recommend future prospective studies using multi-informant assessments of both adverse life events and eating behaviors to further describe the nature and developmental course of this relationship.

Do early-life eating habits predict later autistic traits? Results from a population-based study

Eating problems are common among children with Autism Spectrum Disorder (ASD), but it is unknown to what extent infant eating behavior is associated with later autistic traits. As eating behavior is currently not included in ASD screening instruments, it is important to evaluate whether infant eating behavior predicts later autistic traits and might therefore be used to enhance the early detection of ASD. We investigated the association of breastfeeding and eating behavior during infancy with later autistic traits in the population-based Generation R cohort. We included 3546 mother-child dyads with maternal reports on feeding and eating at age two months and autistic traits at six years. Eating behavior was assessed with seven items on specific eating habits and the Social Responsiveness Scale was used to evaluate autistic traits. Covariates included child sex, and maternal psychopathology and autistic traits. Linear regression analyses showed that being formula fed at two months was associated with a higher autistic trait score at six years (adjusted B = 0.07; 95% CI: 0.00-0.14). Children who were drinking only small quantities (adjusted B = 0.17, 95% CI: 0.04-0.30) and were hungry/not satisfied (adjusted B = 0.23, 95% CI: 0.08-0.39) at age two months also had a higher autistic traits score at age six years. We found no interactions with sex or breastfeeding. This study shows that eating behavior during infancy is related with autistic traits in childhood. Although the associations were fairly small, these findings suggest that early-life eating problems might be relevant for early detection of ASD and a potential addition to ASD-specific screening instruments.

The sex-specific association between autistic traits and eating behavior in childhood: An exploratory study in the general population

Children with Autism Spectrum Disorder (ASD) often exhibit problematic eating behaviors, an observation mostly based on male dominated, clinical ASD study samples. It is, however, important to evaluate both children with an ASD diagnosis and children with subclinical autistic traits as both often experience difficulties. Moreover, considering the suggestion of a possible girl-specific ASD phenotype, there is a need to determine whether autistic traits are related with problematic eating behaviors in girls as well. This study explores the sex-specific association between autism (both autistic traits and diagnosed ASD) and eating behavior in middle childhood in Generation R, a prospective population-based cohort from fetal life onwards. We collected parental reports of autistic traits at six years (Social Responsiveness Scale) and of eating behavior at ten years (Children's Eating Behaviour Questionnaire). In this cohort of 3559 children, autistic traits at six years were associated with more Picky Eating, Emotional Eating and Food Responsiveness in later childhood (e.g. adjusted B for Picky Eating = 0.07; 95% CI: 0.03, 0.11). Stratified analyses showed that in girls, autistic traits were associated with more Emotional Overeating and Emotional Undereating (e.g. adjusted B for Emotional Undereating = 0.12; 95% CI: 0.04, 0.20), while no associations were found for boys. Results comparing children with and without an ASD diagnosis in the cohort largely confirm these associations (e.g. in girls, adjusted B for Emotional Undereating = 0.72; 95% CI: 0.01, 1.42). Our results point to a sex-specific association between autism and eating behavior in middle childhood. Also, our study is the first study to show that autistic traits are associated with emotionally based eating problems in girls and possibly represent part of a girl-specific ASD phenotype.

Fruit and vegetable intakes in relation to behavioral outcomes associated with a nutrition education intervention in preschoolers

BACKGROUND/OBJECTIVES

Although a lot of effort has been put into increasing fruit and vegetable intakes in preschool children, vegetable intake in this group is still low. This study investigated whether nutrition education focusing on fruit and vegetable intakes can affect preschoolers' fruit and vegetable intakes as well as their behavioral outcomes.

SUBJECTS/METHODS

Thirty-five preschoolers (54.3% boys, n = 19) aged 4–6 years residing in Seoul underwent weekly nutrition education intervention (8 sessions) between May and July 2016. Intakes of fruits and vegetables were measured during pre and post-intervention. At snack time, fresh fruit (150 g) and vegetable (120 g) snacks were distributed to each child by teachers. The remaining portions of the snacks were weighed and recorded for each child. Behavioral outcomes were measured by applying Child behavior checklist 1.5–5 and the Diagnostic and statistical manual of mental disorders.

RESULTS

During post intervention, vegetable intake increased from 36.15 ± 30.64 g to 48.01 ± 31.23 g (P = 0.010). Among the emotional and behavioral problems measured by parents, levels of total problems (P = 0.001), internalizing (P = 0.004), externalizing (P = 0.003), anxiety and depression (P = 0.001), and aggressive behavior (P = 0.005) decreased. Anxiety (P = 0.026) score, as measured by teachers, also decreased.

CONCLUSIONS

Nutrition education of preschoolers regarding the intakes of fruits and vegetables had a positive effect on preschoolers' vegetable intake as well as on their emotional and behavioral outcomes. A long-term, large-scale study with a broader study design is warranted to further investigate the role of fruit and vegetable intake in cognitive development and behavior of preschoolers.

Picky eating in children: causes and consequences

Picky eating is a common behaviour in early childhood. There is neither a universally accepted definition of picky eating, nor is there agreement on the best tool to identify it. Causes of picky eating include early feeding difficulties, late introduction of lumpy foods at weaning, pressure to eat and early choosiness, especially if the mother is worried by this; protective factors include the provision of fresh foods and eating the same meal as the child. The consequences for the child's diet include poor dietary variety and a possible distortion of nutrient intakes, with low intakes of iron and zinc (associated with low intakes of meat, and fruit and vegetables) being of particular concern. Low intakes of dietary fibre, as a result of low intakes of fruit and vegetables, are associated with constipation in picky eaters. There may be developmental difficulties in some children with persistent picky eating. There is little evidence, however, for a consistent effect of being a picky eater on growth trajectories. There may be a small subgroup of children in whom picky eating does not resolve who might be at risk of thinness during adolescence, or of developing an eating disorder or adult picky eating: these children need to be identified at an early age to enable support, monitoring and advice to be offered to parents. Strategies for avoiding or ameliorating picky eating include repeated exposures to unfamiliar foods, parental modelling of eating fruit and vegetables and unfamiliar foods, and the creation of positive social experiences around mealtimes.

Autism spectrum disorder and food neophobia: clinical and subclinical links

Background

Autism spectrum disorder (ASD) has been linked with eating- and feeding-related atypicalities, including food neophobia (FN) (refusal to try unfamiliar foods), since its earliest description. Nevertheless, whether associations between ASD traits and FN extend subclinically into the broader population of children and their potential additive health impacts remains unexplored.

Objective

We examined ASD-control group differences in FN and ASD trait-FN trait associations, as well as the ability of FN and autistic traits to predict one index of later health-related outcomes [body mass index (BMI)].

Design

Participants in the present study were a large community-based sample of 8- to 11-y-olds (n = 4564), including a relatively small group of children diagnosed with ASD (n = 37). Parents of these 8- to 11-y-old children completed assessments of FN and autistic traits and provided height and weight metrics at 12 y of age.

Results

Children with ASD were rated as more food neophobic than their same-age non-ASD peers (2.67 ± 0.83 compared with 2.22 ± 0.73; P < 0.001), and there were subclinical associations between FN and ASD traits (social, communication, and restricted/repetitive behavior) in this community-based sample of children (P < 0.05). Moreover, whereas FN alone predicted lower BMI, the interaction of FN and ASD traits predicted higher BMI (P ≤ 0.01), suggesting that elevated ASD traits in combination with FN exert opposing influences on weight compared with FN alone.

Conclusions

These findings implicate clinical and subclinical connections between ASD traits and feeding behaviors that could affect health outcomes and therefore should be further explored in future studies of shared etiology and intervention strategy.

Home feeding environment and picky eating behavior in preschool-aged children: A prospective analysis

OBJECTIVE

Picky eating is prevalent in young children and is associated with poor dietary quality and nutrient deficiencies. Identifying predictors of picky eating could inform the development of anticipatory feeding guidance for parents and caregivers of young children. This study identified the association between factors of the home feeding environment with picky eating behavior in a cohort of preschool-aged children.

METHODS

Parents of preschool-aged children (n = 497) completed questionnaires including measures of the home feeding environment (i.e., television during mealtime, family mealtime routines, and feeding practices) and child picky eating behavior. The questionnaire was repeated one year later, in which 326 parent-child dyads participated. Logistic regression was used to determine the cross-sectional and prospective associations between home feeding environment measures and child picky eating behavior outcomes.

RESULTS

Child control over feeding and watching television during mealtime were associated with higher odds of picky eating behavior in both cross-sectional and prospective analyses. A higher sense of positive climate during family meals and mealtime ritualization was associated with lower odds of picky eating behavior one year later.

CONCLUSION

The home feeding environment plays a role in the development of young children's picky eating behavior. Avoiding the television and maintaining parent control of food choices during mealtimes could lead to improvements in children's food preferences and dietary intake.

A multidimensional approach to understanding the potential risk factors and covariates of adult picky eating

OBJECTIVE

Adult picky eating (PE) has received increased attention in the eating behavior literature due to its important association with adult avoidant-restrictive food intake disorder (ARFID). The current study tested a model of potential risk factors of adult PE behavior, including perceived early parental feeding practices. An exploratory model was also utilized to understand associations with different aspects of adult PE behaviors.

METHODS

A sample of 1339 US adults recruited through Amazon's MTurk completed an online survey that included the recently developed Adult Picky Eating Questionnaire (APEQ), retrospective reports of parental feeding practices, and other measures of eating behavior and demographic variables. A structural equation modeling procedure tested a series of regression models that included BMI and disordered eating behaviors as covariates.

RESULTS

SEM modeling indicated that retrospective reports of greater parental pressure to eat, higher disgust sensitivity, lower PE age of onset, and experiencing an aversive food event were associated with general adult PE behavior. Results also indicated parental encouragement of healthy eating may be a protective factor, and that men endorsed higher levels of adult PE. Exploratory analyses indicated that cross-sectional predictors and covariates were differentially related to specific aspects of PE as measured by the APEQ subscales.

CONCLUSIONS

Early experiences, including parental approaches to feeding, appear to be potential risk factors of PE behavior in adults. A nuanced understanding of adult PE is important for the prevention and treatment of severe PE behaviors, related psychosocial impairment, and ARFID.

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.

RECENT FINDINGS

Fussy eating and neophobia are related concepts with both genetic and environmental aetiologies. Parent-child correlations and heritability estimates are moderate to high for both traits, but aspects of the family environment remain influential in young children, although no longer in young adults. Parental strategies based around repeat tasting opportunities can improve acceptance of disliked foods in even the fussiest children. Fussy eating and neophobia are not risk factors for obesity but could limit growth in severe cases. Fussy eating and food neophobia are common concerns for parents, though health risks are low. Dissemination of evidence-based strategies to parents that can encourage a more varied diet in young children would be helpful.
