Considering Nature and Nurture in the Etiology and Prevention of Picky Eating: A Narrative Review

Children are often categorized as picky eaters by parents and caregivers for their rejection of foods, such as vegetables, and for exhibiting other difficult mealtime behaviors. However, there are several factors that contribute to these mealtime behaviors, including early feeding practices (i.e., breastfeeding, introduction to solid food), repeated exposure to novel foods, and genetic taste sensitivity to certain compounds. Using the online database of PubMed, a review of the literature on the development of picky eating in children, its outcomes, and intervention strategies was conducted. This review groups the developmental contributors to picky eating into the categories of nature and nurture and explores the interaction between the two. This paper will also summarize the potential outcomes of picky eating and the various strategies that are currently recommended to mitigate picky eating in young children. However, there is a lack of longitudinal work targeting consistent picky eating behaviors that have the potential to impact long-term food preferences and dietary variety. Future intervention strategies should address the factors that influence the development of picky eating on an individual level.

Ultra-processed food consumption, appetitive traits and BMI in children: a prospective study

This study aimed to investigate the association of ultra-processed food consumption at 4 and 7 years of age with appetitive traits at 7 years and BMI at 10 years of age. Participants were 1175 children of the population-based birth cohort Generation XXI, who provided food diaries and complete data on socio-demographic variables, anthropometric measures and the Portuguese Children's Eating Behaviour Questionnaire (P-CEBQ). Foods were grouped according to NOVA classification into: 'unprocessed, minimally or moderately processed, and culinary preparations'; 'processed' and 'ultra-processed'. To assess tracking of groups' consumption, Pearson's correlation coefficient (r) and the intraclass correlation coefficient (ICC) were calculated. Generalised linear models were fitted to test main associations, mediators and interactions among the variables. Ultra-processed consumption exhibited a fair level of stability between ages 4 and 7 years (r 0·34; ICC = 0·32; 95 % CI 0·25, 0·39), corresponding, respectively, to 27·3 % (1881·9 (SD 908·8) kJ/d) and 29·3 % (2204·5 (SD 961·1) kJ/d) of total energy intake. After adjusting for maternal and child characteristics, higher ultra-processed consumption at 4 years was associated directly with 'Food Responsiveness' (β = 0·019; 95 % CI 0·007, 0·037) and indirectly through energy intake with avoidant traits: 'Food Fussiness' (β = -0·007; 95 % CI 0·002, 0·012) and 'Satiety Responsiveness' (β = -0·007; 95 % CI 0·003, 0·012). Ultra-processed consumption at 4 years old was associated with BMI at 10 years old, but appetitive behaviours were not powerful mediators of this association. The results suggest a path by which ultra-processed products may impact on later appetitive traits and higher BMI in children.

Nutritional concerns of survivors of childhood cancer: A "First World" perspective

Childhood cancer survivor (CCS) numbers are increasing as a result of advances in both treatment and supportive care. This positive outcome is tempered by the recognition of a high burden of chronic health conditions. Here, we review the nutritional concerns of CCS, including dietary habits after treatment and the factors during treatment that may contribute to chronic health conditions. Dietary interventions that have been conducted in CCS will be summarized along with focused goals of these interventions. We will also address the need to leverage these interventions to reduce the risk of chronic disease in CCS.

Associations between appetitive traits, dietary patterns and weight status of children attending the School Kids Intervention Program

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 children (N = 58, body mass index z-score: 2.25±0.46), 4-12 years attending the School Kids Intervention Program. Children's appetitive traits and dietary patterns were measured with the Child Eating Behaviour Questionnaire and Children's Dietary Questionnaire, respectively. Children's height and weight were used to compute body mass index z-score; waist circumference was also measured and waist-to-height ratio was calculated.

RESULTS

After controlling for children's age and gender, hierarchical linear regression analyses showed that lower scores for slowness in eating were associated with higher body mass index z-scores in children (β = -0.31, p = 0.01). Higher scores for emotional overeating were associated with higher waist-to-height ratio in children (β = 0.48, p = 0.01). Higher scores for fussiness were correlated with lower scores for fruits and vegetables (β = -0.59, p < 0.001) and higher scores for non-core foods (β = 0.26, p = 0.04).

CONCLUSION

Results observed in the current sample of overweight and obese children are consistent with previous studies examining healthy-weight children. Slowness in eating may foster an obesity 'protective' effect, whereas emotional overeating may promote susceptibility to weight gain. Fussy eating may impair diet quality by lower consumption of vegetables and fruits and higher intake of non-core foods. This evidence will support dietitians to consider children's appetitive traits when providing dietary consultation to support obesity management among overweight/obese children.

"Food" and "non-food" self-regulation in childhood: a review and reciprocal analysis

BACKGROUND

In developmental science, there is an extensive literature on non-food related self-regulation in childhood, where several domains relating to emotions, actions and cognitions have been identified. There is now growing attention to food related self-regulation in childhood, especially difficulties with ASR, and the consequences for weight gain and adiposity. The aim of this narrative review was to conduct a reciprocal analysis of self-regulation in the food and non-food domains in childhood (referred to as appetite self-regulation (ASR) and general self-regulation (GSR) respectively). The focus was on commonalities and differences in key concepts and underpinning processes.

METHODS

Databases and major journals were searched using terms such as self-regulation, appetite self-regulation, or self-regulation of energy intake, together with associated constructs (e.g., Executive Function, Effortful Control, delay-of-gratification). This was followed by backward and forward snowballing.

RESULTS AND DISCUSSION

The scholarship on GSR in childhood has had a focus on the role of the cognitively-oriented Executive Function (EF), the temperamentally-based Effortful Control (EC) and the recursive interplay between bottom-up (reactive, emotion driven, approach or avoidance) and top-down (cognitive, conscious decision-making) processes. "Hot" and "cool/cold" EF and self-regulation situations have been distinguished. There were some parallels between GSR and ASR in these areas, but uncertainty about the contribution of EF and EC to ASR in young children. Possible differences between the contribution to ASR-related outcomes of delay-of-gratification in food and non-food tasks were apparent. Unique elements of ASR were identified; associated with psychological, biological and neurological responses to food and bottom-up processes. A diverse number of situations or elements connected to ASR exist: for example, energy balance homeostasis, caloric compensation, hunger regulation, satiation, satiety, energy density of food, eating in the absence of hunger, emotional eating, etc. CONCLUSIONS: Self-regulation in food and non-food domains are amenable to a reciprocal analysis. We argue that self-regulation of appetite should be added as a domain under the umbrella of self-regulation in childhood along with the other non-food related domains. This could lead to a broader understanding of self-regulation in childhood, and generate novel lines of enquiry.

Maternal anxiety and diet quality among mothers and toddlers from low-income households

We evaluated the association between maternal anxiety score and diet quality over time among mothers and toddlers in low‐income families. Longitudinal data were collected from 267 mother–toddler dyads in an obesity prevention trial. Participants were recruited from the Special Supplemental Nutrition Program for Women, Infants and Children and paediatric clinics between 2007 and 2010. Dyads were assessed at study enrolment (Time 1), 6‐month (Time 2), and 12‐month follow‐up (Time 3). On the basis of a 1‐day 24‐hr dietary recall, we estimated maternal and toddler diet quality using the Healthy Eating Index 2015. Anxiety, a time‐varying variable, was assessed via the State–Trait Anxiety Inventory. Associations between maternal anxiety score and maternal and toddler diet quality over time were assessed in adjusted mixed models. Maternal and toddler diet quality were positively correlated (r = .48, p < .001). Higher maternal anxiety scores were related to lower toddler Healthy Eating Index scores (b = −0.51, 95% confidence interval, CI [−0.87, −0.15]) with no significant variation over time. The relation between maternal diet quality and anxiety score varied over time (b = 0.28, p = .03, for time–anxiety interaction). Higher maternal anxiety scores were associated with lower maternal diet quality at Time 1 (b = −0.71, 95% CI [−1.09, 0.34]) and at Time 2 (b = −0.51, 95% CI [−0.97, −0.05]), but not at Time 3 (b = −0.14, 95% CI [−0.54, 0.26]). Findings suggest that mothers and toddlers exhibited similar low‐quality dietary patterns and that lower diet quality was associated with higher maternal anxiety scores. Approaches to enhance diet quality may consider incorporating anxiety‐reducing strategies into maternal and toddler care and feeding behaviour guidelines.

Food Insecurity among College Students in the United States: A Scoping Review

Reports of college students experiencing food insecurity (FI), defined as inadequate access, availability, adequacy, and stability of food, have sparked national calls for alleviation and prevention policies. However, there are a wide variety of FI rates reported across studies and even among recent literature reviews. The current scoping review aimed to develop a weighted estimated prevalence of FI among US students using a comprehensive search approach. In addition, study characteristics that may be related to the high variability in reported FI prevalence were explored. To address these aims, the peer-reviewed and gray literature on US college student FI was systematically searched to identify 12,044 nonduplicated records. A total of 51 study samples, across 62 records, met inclusion criteria and were included in the current review. The quality of the included studies was moderate, with an average rate of 6.4 on a scale of 0-10. Convenience (45%) and census (30%) sampling approaches were common; only 4 study samples were based on representative sampling strategies. FI estimates ranged from 10% to 75%. It was common for very low security to be as prevalent as, or more prevalent than, low food security. The surveying protocols used in the studies were related to the FI estimates. The USDA Short Form Food Security Survey Module (FSSM; 50%) and the USDA Adult FSSM (40%) prevalence estimates were larger than for the full USDA Household FSSM (13%). When these surveys referenced a 12-mo period, FI estimates were 31%. This was a lower FI estimate than surveys using reference periods of 9 mo or shorter (47%). The results indicate that FI is a pressing issue among college students, but the variation in prevalence produced by differing surveys suggests that students may be misclassified with current surveying methods. Psychometric testing of these surveys when used with college students is warranted.

The Environmental and Bitter Taste Endophenotype Determinants of Picky Eating in Australian School-Aged Children 7-12 years-A Cross-Sectional Pilot Study Protocol

Caregivers’ perceptions of children’s pickiness are relatively scarce in relation to the five core food groups and their importance in providing a nutritionally balanced diet. Furthermore, there is no validated questionnaire that examines child-reported food preferences in an age-appropriate manner, and the use of terms such as a “picky eater” can be attributed to environmental and genetic factors. Despite potential links between children’s food preferences and endophenotype bitter taste, associations between bitter taste sensitivity and picky eating is relatively unexplored. The proposed cross-sectional study aims to develop and validate a parent-reported core-food Picky Eating Questionnaire (PEQ) and child-reported Food Preference Questionnaire (C-FPQ) and simultaneously investigate environmental and phenotype determinants of picky eating. The study will be conducted in three stages: Phase 1, piloting PEQ and C-FPQ questionnaires (15–20 primary caregivers and their children aged 7–12 years); Phase 2 and 3, validating the revised questionnaires and evaluating the 6-n-propylthiouracil (PROP) bitter taste sensitivity to examine perception to bitter taste (369 primary caregivers and their children). Study findings will generate new validated tools (PEQ, C-FPQ) for use in evidence-based practice and research and explore picky eating as a behavioural issue via the potential genetic-phenotype basis of bitter taste sensitivity.

Associations between breastfeeding mode and duration and food neophobia in toddlerhood: A cross-sectional study among Norwegian toddlers

Background

Research on the association between breastfeeding duration and food neophobia is inconclusive. Breastfeeding and measures to reduce food neophobia are highly recommended to ensure a healthy diet early in life.

Objective

The aim of this study was to evaluate the association between breastfeeding duration and food neophobia in young Norwegian children.

Design

Participants (n = 246) were recruited through kindergartens in four Norwegian counties in 2017. The parents of 1-year-olds filled in questionnaires, including standardized questions on breastfeeding and food neophobia. Cross-sectional results are presented. Comparisons of child neophobia score at 16 months of age according to breastfeeding status at various timepoints during infancy were explored in linear regression models adjusted for maternal education and parental food neophobia.

Results

Still being breastfed at 12 months and being exclusively breastfed at 5 months were independently associated with slightly higher food neophobia score at the mean age of 16 months compared to shorter duration of breastfeeding. We found no other associations between breastfeeding duration and child food neophobia.

Discussion

Our study adds to the somewhat scarce literature regarding associations between breastfeeding mode and duration and later food neophobia; some literature shows protective relations between breastfeeding and food fussiness, and others report opposite or null findings.

Conclusion

We found that both being breastfed at 12 months and being exclusively breastfed at 5 months were independently associated with slightly higher food neophobia score at the mean age of 16 months compared to shorter duration of breastfeeding. As the data are derived from a cross-sectional study, these findings should be interpreted with caution.

Childhood fussy/picky eating behaviours: a systematic review and synthesis of qualitative studies

Fussy/picky eating behaviours are common across childhood. Recent reviews of the fussy eating literature focus on quantitative research and do not adequately account for families' subjective experiences, perceptions and practices. This review aims to synthesise the increasing volume of qualitative work on fussy eating. A systematic search of relevant databases was carried out. Studies were included if they were qualitative, published since 2008, with a primary focus on families' experiences, perceptions and practices regarding fussy eating, food neophobia, or food refusal in children (aged one to young adult). Studies with clinical samples, or relating to children under one year were excluded. Ten studies were eligible for this review and were synthesised using meta-ethnography (developed by Noblit and Hare). This review provides a comprehensive description and definition of fussy eating behaviours. A conceptual model of the family experience of fussy eating was developed, illustrating relationships between child characteristics (including fussy eating behaviours), parent feeding beliefs, parent feeding practices, mealtime emotions and parent awareness of food preference development. Our synthesis identified two ways in which fussy eating relates to mealtime emotions (directly and via parent feeding practices) and three distinct categories of parent beliefs that relate to fussy eating (self-efficacy, attributions and beliefs about hunger regulation). The model proposes pathways which could be explored further in future qualitative and quantitative studies, and suggests that parent beliefs, emotions, and awareness should be targeted alongside parent feeding practices to increase effectiveness of interventions. The majority of studies included in this review focus on pre-school children and all report the parent perspective. Further research is required to understand the child's perspective, and experiences of fussy eating in later childhood. PROSPERO Registration: CRD42017055943.

Maternal Depressive Symptoms and Perceived Picky Eating in a Low-Income, Primarily Hispanic Sample

OBJECTIVE

Feeding concerns are common in the first 2 years of life and typically reflect maternal perceptions occurring within the larger context of the parent-child relationship. We aimed to determine whether (1) maternal depressive systems predicted perceived picky eating, mediated by maternal negative perceptions; (2) receipt of the Video Interaction Project (VIP) parenting intervention impacted perceived picky eating through this pathway; and (3) perceived picky eating was associated with child growth or subsequent dietary patterns.

METHODS

We performed a partial longitudinal analysis of 187 low-income, predominantly Hispanic mother-child dyads enrolled in a randomized controlled trial of the VIP. Mother-infant dyads were enrolled postpartum in an urban public hospital. Participants randomized to the VIP met with an interventionist on days of well-child visits; sessions were designed to facilitate interactions in play and shared reading through provision of learning materials and review of videotaped parent-child interaction; the curriculum did not contain feeding-specific elements. We used structural equation modeling to determine direct, indirect, and total effects of maternal depressive symptoms, maternal negative perceptions, and the VIP on perceived picky eating. We then tested associations between perceived picky eating and (1) child growth, using multivariable linear regression and multilevel modeling; and (2) subsequent child dietary consumption, using multivariable multinomial logistic regression.

RESULTS

Maternal depressive symptoms had significant total effects on negative maternal perceptions (β = 0.32, p < 0.001) and perceived picky eating (β = 0.21, p < 0.01) after controlling for potential confounders. This effect was partially mediated by maternal negative perceptions (indirect effect: β = 0.06, p = 0.04). When used in the model as the predictor, the VIP had a significant total effect on perceived picky eating (β = -0.16, p = 0.02), which was partially mediated by maternal depressive symptoms and negative perceptions (indirect effect: β = -0.05, p = 0.02). Perceived picky eating was not associated with child diet at age 2 years or adiposity from 6 months to 3 years.

CONCLUSION

Maternal concerns about picky eating may reflect deeper depressive symptoms and negative perceptions of her child's behavior. Interventions designed to facilitate positive parenting in general may lessen feeding-specific concerns, such as picky eating. Although reassurance about growth and nutritional outcomes for children perceived as picky eaters is appropriate, clinicians should also consider probing for underlying symptoms of depression that could lead to eating concerns.

A Biopsychosocial Model of Sex Differences in Children's Eating Behaviors

The prevalence of obesity and eating disorders varies by sex, but the extent to which sex influences eating behaviors, especially in childhood, has received less attention. The purpose of this paper is to critically discuss the literature on sex differences in eating behavior in children and present new findings supporting the role of sex in child appetitive traits and neural responses to food cues. In children, the literature shows sex differences in food acceptance, food intake, appetitive traits, eating-related compensation, and eating speed. New analyses demonstrate that sex interacts with child weight status to differentially influence appetitive traits. Further, results from neuroimaging suggest that obesity in female children is positively related to neural reactivity to higher-energy-dense food cues in regions involved with contextual processing and object recognition, while the opposite was found in males. In addition to differences in how the brain processes information about food, other factors that may contribute to sex differences include parental feeding practices, societal emphasis on dieting, and peer influences. Future studies are needed to confirm these findings, as they may have implications for the development of effective intervention programs to improve dietary behaviors and prevent obesity.

Eating Veggies Is Fun! An Implementation Pilot Study in Partnership With a YMCA in South Los Angeles

PURPOSE AND OBJECTIVES

Children eat less than recommended amounts of vegetables. Repeated taste exposure can increase children's acceptance of initially disliked vegetables. However, implementation of this strategy is lacking. We conducted a pilot study to assess the feasibility of implementing an evidence-based intervention to promote liking of initially disliked vegetables among children enrolled in a YMCA summer camp.

INTERVENTION APPROACH

We adapted a research-tested intervention to promote child liking of vegetables for implementation in small groups. In summer 2015, 50 children aged 7 to 12 years were invited to taste 5 initially disliked vegetables daily for 10 days.

EVALUATION METHODS

Children rated how much they liked vegetables on a 5-point emoji-like faces Likert scale at baseline and 2- and 4-week follow-up. The mean ratings for liked and initially disliked vegetables were estimated over time using mixed effects modeling.

RESULTS

We achieved excellent participation of parents and children; however, we experienced nonstudy-related attrition caused by disenrollment of some children from the weekly camp program. The average liking increased over time (linear trend, P = .003) for the 5 targeted vegetables but not for the other nontargeted vegetables, as predicted.

IMPLICATIONS FOR PUBLIC HEALTH

This pilot study suggests that repeated vegetable tasting opportunities offered by community programs may be a practical strategy for introducing low-income, young children to new or initially disliked vegetables. The study demonstrates the feasibility of implementing a health promotion strategy that has the potential to improve population health in a community setting in an underresourced neighborhood.

Picky eating - A risk factor for underweight in Finnish preadolescents

BACKGROUND

Picky eating (PE) is the most common cause of early-life feeding problems. However, the consequences of PE on food intake and weight development in general populations have not been established.

OBJECTIVES

This study aims to investigate the associations of PE and food neophobia (FN) with weight status in 5700 Finnish preadolescents. In addition, we described food consumption by PE/FN status.

MATERIAL AND METHODS

We utilised the Finnish Health in Teens (Fin-HIT) cohort of 9-12-year-old preadolescents, who were categorised as having PE and FN based on answers from parental questionnaires. Weight was categorised as underweight, normal weight, and overweight/obesity based on body mass index (BMI) according to IOTF age- and sex-specific cut-offs. Eating patterns were obtained with a 16-item food frequency questionnaire. Multinomial logistic regression models were used to estimate odds ratios (OR) and 95% confidence intervals (CIs).

RESULTS

The overall prevalence of PE and FN were 34% and 14%, respectively. PE was inversely associated with overweight/obesity (OR = 0.7; 95% CI 0.6-0.8) and led to a higher risk of underweight (OR = 2.0; 95% CI 1.7-2.4), while this was not observed with FN. Compared with preadolescents without PE/FN, those with PE/FN reported consuming unhealthy foods such as pizza, hamburgers/hot dogs, and salty snacks more frequently (p < 0.0038). By the same token, these preadolescents reported consuming healthy foods such as cooked vegetables, fresh vegetables/salad, fruit/berries, milk/soured milk, and dark bread less frequently.

CONCLUSIONS

Among Finnish preadolescents, only PE was associated with a higher risk for underweight and inversely with overweight/obesity. PE and FN were accompanied with unhealthy eating patterns. Management of PE in children may be explored as a potential strategy for improving healthy eating and avoiding underweight in preadolescents.

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.

Concern Explaining Nonresponsive Feeding: A Study of Mothers' and Fathers' Response to Their Child's Fussy Eating

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 mother-father pairs (n = 208) with children aged 2-5 years.

MAIN OUTCOME MEASURE(S)

Two validated measures of nonresponsive feeding: persuasive feeding and reward for eating.

ANALYSIS

Mediation analysis tested concern as a mediator of the relationship between child food fussiness (independent variable) and parent nonresponsive feeding practices (dependent variables), adjusted for significant covariates and modeled separately for mothers and fathers.

RESULTS

Maternal concern fully mediated the relationship between child food fussiness and persuasive feeding (indirect effect: B [SE] = 0.10 [0.05]; 95% confidence interval [CI], 0.01-0.20). Concern also fully mediated the relationship between child food fussiness and reward for eating for mothers (indirect effect: B [SE] = 0.17 [0.07]; CI, 0.04-0.31) and fathers (indirect effect: B [SE] = 0.14 [0.05]; CI, 0.04-0.24) CONCLUSIONS AND IMPLICATIONS: Concern for fussy eating behaviors may explain mothers' and fathers' nonresponsive feeding practices. In addition to providing education and behavioral support, health professionals working with socioeconomically disadvantaged families can incorporate strategies that aim to alleviate parents' concerns about fussy eating.

Duration of exclusive breastfeeding may be related to eating behaviour and dietary intake in obesity prone normal weight young children

Infants who are breastfed are introduced to a variety of flavours from the maternal milk, and thus the transition from maternal milk to complementary foods may be easier for these children. The aim of this study was to investigate if duration of exclusive breastfeeding was associated with pickiness or dietary intake of vegetables, fruit, starchy foods or sugar sweetened beverages among obesity prone normal weight children aged 2–6 years. This cohort study was based on data from the Healthy Start primary intervention study, the Danish Medical Birth registry and the Danish Health Visitor’s Child Health Database. Infant feeding was registered by health nurses while home-visiting the mother and child up to four times within the first year. Information on eating behaviour and diet intake at age 2–6 years was obtained by parents. Crude and adjusted logistic and general linear regression models were used to investigate associations. A total of 236 children had complete information on all variables. Data showed lower odds of picky eating behaviour when exclusively breastfed until age 4–5 months compared to exclusively breastfed for 0–1 months (OR = 0.35, 95CI = 0.16;0.76, p = 0.008). In the crude analysis only, exclusively breastfed until age 6–10 months was associated with a higher daily intake of vegetables (p = 0.04). This study suggests that exclusive breastfeeding duration seems to influence pickiness and may contribute to facilitate the consumption of more vegetables in later childhood in obesity prone normal weight children.

Sensory sensitivity mediates the relationship between anxiety and picky eating in children/ adolescents ages 8-17, and in college undergraduates: A replication and age-upward extension

This study explores the relationships among anxiety, sensitivity to sensory stimuli, and picky eating (PE). An earlier study in 95 children ages 5-10 found that sensory sensitivity fully mediated the relationship between anxiety and picky eating. We replicated this finding in a sample of 158 children, ages 8-17, and in 813 young adult college students. As in the previous child sample, the relationship between anxiety and picky eating appears to be mediated by sensory sensitivity. This relationship extends into adolescence and young adulthood and holds even in a sample of children with obsessive-compulsive-spectrum and anxiety disorders. However, there may be developmental differences in the relationship between sensory sensitivity and PE; the magnitude of this relationship was significantly greater for children than young adults. Although there was a trend towards a stronger relationship in a subsample of young adults with high anxiety, the effect was still smaller than that observed in children, suggesting that this difference is developmental and not completely driven by higher anxiety in the child sample. Sensory sensitivity is a candidate mechanism of picky eating, although the cross-sectional nature of this study means that we cannot address whether it is an etiological or maintaining mechanism, or both. Implications for behavioral treatment of picky eating in clinically anxious and non-clinical samples are discussed.

Factors Influencing Children's Eating Behaviours

Relevant factors involved in the creation of some children’s food preferences and eating behaviours have been examined in order to highlight the topic and give paediatricians practical instruments to understand the background behind eating behaviour and to manage children’s nutrition for preventive purposes. Electronic databases were searched to locate and appraise relevant studies. We carried out a search to identify papers published in English on factors that influence children’s feeding behaviours. The family system that surrounds a child’s domestic life will have an active role in establishing and promoting behaviours that will persist throughout his or her life. Early-life experiences with various tastes and flavours have a role in promoting healthy eating in future life. The nature of a narrative review makes it difficult to integrate complex interactions when large sets of studies are involved. In the current analysis, parental food habits and feeding strategies are the most dominant determinants of a child’s eating behaviour and food choices. Parents should expose their offspring to a range of good food choices while acting as positive role models. Prevention programmes should be addressed to them, taking into account socioeconomic aspects and education.

Biological and Psychosocial Processes in the Development of Children's Appetitive Traits: Insights from Developmental Theory and Research

There has been increasing concern expressed about children's food intakes and dietary patterns. These are closely linked to children's appetitive traits (such as disinhibited eating and food fussiness/neophobia). Research has examined both biological and psychosocial correlates or predictors of these traits. There has been less focus on possible processes or mechanisms associated with children's development of these traits and research that links biological and psychosocial factors. There is an absence of research that links biological and psychosocial factors. In the present article, we outline a model intended to facilitate theory and research on the development of appetitive traits. It is based on scholarship from developmental theory and research and incorporates biological factors such as genetic predispositions and temperament as well as psychosocial factors in terms of parent cognitions, feeding styles and feeding practices. Particular attention is directed to aspects such as emotional eating and feeding, self-regulation of energy intake, and non-shared family environments. We highlight the opportunity for longitudinal research that examines bidirectional, transactional and cascade processes and uses a developmental framework. The model provides a basis for connecting the biological foundations of appetitive traits to system-level analysis in the family. Knowledge generated through the application of the model should lead to more effective prevention and intervention initiatives.
