Dyadic Predictors of Willing to Engage in Physical Activity and Emotional Eating in Children and Adolescents with Mild and Moderate Intellectual Disability

Intellectual disability is associated with increased risk for childhood obesity, and the factors most often associated with this risk are incorrect eating behavior and insufficient amount and intensity of physical activity. As is well known, there area whole range of factors determining lifestyle, but many currently available reports in this field refer to the functioning of children without a diagnosis of intellectual disability, and, as we know, due to numerous individual and environmental barriers, children with ID may function differently in this context than their peers. Therefore, we examined the relationships between the selected variables and divided them into two models: (1) first regression model: child's willingness to engage in physical activity (dependent variable), child's physical limitations related to disabilities and/or comorbidities, child's independence, parents' willingness to engage in physical activity, child's body dissatisfaction (independent variables/predictors); (2) second regression model: child's emotional eating (dependent variable), child's coping with emotions, parents' attitudes, beliefs, and practices about child feeding (restriction and pressure to eat), parents' emotional eating, parents' happiness (independent variables/predictors). A group of 503 parents (of children and adolescents with mild and moderate intellectual disability) completed: the Contour Drawing Rating Scale, the Child Feeding Questionnaire, the Emotional Overeating Questionnaire, the Scale of Experiencing Happiness, and the supplementary survey. Our results allow partial confirmation of the hypotheses related to both of these models: (1) model I: the relationships between the child's willingness to engage in physical activity and all predictors are significant, but the direction of the relationship between the dependent variable and one of the predictors-body dissatisfaction-is opposite to the assumed one (negative relationship); (2) model II: the relationships between the child's emotional eating and almost all predictors are significant, except for the relationship between the dependent variable and pressure to eat. In conclusion, (to the authors' knowledge) this study is the first to assess dyadic predictors of willingness to engage in physical activity and emotional eating in children and adolescents with mild and moderate intellectual disability. It allows for a better understanding of the attitudes, beliefs, and experiences of children with intellectual disabilities and their parents, which gives the opportunity (taking into account factors from both individuals from the child-parent dyad) to better design strategies to support pro-health behaviors in children and adolescents from this group (which may improve the effectiveness of overweight prevention and obesity). These findings emphasize how important it is to consider the dynamic of the child-parent dyad when considering how parenting contributes to a child's willingness to engage in physical activity, as well as thatchild's emotional eating.

You are what you eat-ecological niche and microhabitat influence venom activity and composition in aquatic bugs

True water bugs (Nepomorpha) are mostly predacious insects that live in aquatic habitats. They use their piercing-sucking mouthparts to inject venomous saliva that facilitates the capture and extra-oral digestion of prey animals, but their venom can also be deployed for defence. In Central Europe, nepomorph species representing different families coexist in the same habitat. However, their feeding ecology, including venom composition and deployment, has not been investigated in detail. We used an integrated proteotranscriptomic and bioactivity-based approach to test whether venom composition and activity differ between four water bug species sharing the same habitat but occupying different ecological niches. We found considerable species-dependent differences in the composition of digestive enzymes and venom components that probably evolved as adaptations to particular food sources, foraging strategies and/or microhabitats. The venom of Corixa punctata differed substantially from that of the three strictly predatory species (Ilyocoris cimicoides, Notonecta glauca and Nepa cinerea), and the abundance of herbivory-associated proteins confirms a mostly plant-based diet. Our findings reveal independent adaptations of the digestive and defensive enzyme repertoires accompanied by the evolution of distinct feeding strategies in aquatic bugs.

The association between parents' stress and parental feeding practices and feeding styles: Systematic review and meta-analysis of observational studies

In the extended UNICEF framework of early childhood nutrition, parents' stress is associated with parental feeding style. However, no comprehensive review has examined the association between parents' stress and feeding styles and practices. The objective of our review was to synthesise the current literature examining the association between parents' stress and their feeding practices and/or styles, among parents of children ≤ 5 years old. We searched; MEDLINE, EMBASE, PSYCHINFO and CINAHL from 2019 to 2021. Two investigators independently extracted relevant data and assessed the study quality and the certainty of evidence. Data were pooled using generic inverse variance with fixed effects (<5 comparisons) or random effects (≥5 comparisons) and expressed as correlation coefficients with 95% confidence intervals (CI). Between study heterogeneity was assessed using Cochran's Q and quantified with I² . We identified 6 longitudinal and 11 cross-sectional studies, of which 4 studies provided sufficient data to be pooled. A very small correlation between general stress and restrictive feeding practices was observed (r = 0.06 [95% CI: 0.01-0.12]; no substantial heterogeneity (I²  = 0.00%, P_Q  < 0.85, very low certainty). No correlation between general stress and feeding pressure was identified (r = 0.06 [95% CI: -0.02 to 0.15]). Results showed that both general and parenting stress were associated with suboptimal breastfeeding practices and unresponsive feeding styles. Conclusion: This study demonstrated a low-to-moderate quality of literature for the inclusion of parents' stress in the extended UNICEF care model of child nutrition. Future research needs to explore this relationship longitudinally and in ethnic diverse populations to inform tailored interventions that promote responsive feeding practices.

Feeding difficulties in Asian children with autism spectrum disorder

BACKGROUND

To characterize the nature and severity of feeding difficulties in Asian young children with Autism Spectrum Disorders (ASD) and identify potential predictors of poorer feeding outcomes.

METHODS

Cross sectional study of children aged 1-7 years with ASD. Parents completed the following: demographic information, brief autism mealtime behavior inventory, aberrant behavior checklist (ABC), behavioral pediatrics feeding assessment scale (BPFAS) and caregiver feeding style questionnaire. Additional information (medical data, cognitive and developmental assessment results, e.g., Autism Diagnostic Observation Schedule Second Edition, Autism Diagnostic Interview, Revised, Vineland Adaptive Behaviour Scales, etc.) were subsequently obtained from electronic medical records retrospectively by one of the study team members.

RESULTS

Of the 67 children, 28.4% had feeding difficulties (high BPFAS total frequency score). Caregiver feeding styles were authoritarian (34.8%) or indulgent (39.4%). Child characteristics did not significantly predict for the severity of feeding difficulties. Univariate analysis revealed that authoritarian feeding style (p = 0.001) and ABC hyperactivity score (p = 0.006) were significantly associated with BPFAS severity score. Multivariate analysis revealed that ABC hyperactivity score remained significantly associated with BPFAS severity score after controlling for all other ABC subscale scores. A final regression model including all child characteristics and ABC scores did not reveal any significant predictors of BPFAS total frequency score (R2 = 0.557).

CONCLUSION

Our findings suggest an association between hyperactivity, authoritarian feeding style and feeding difficulties. Children with ASD who have significant hyperactivity behaviors in the context of parents with an authoritarian feeding style should be actively screened for problematic feeding behaviors.

Precision Food Parenting: A Proposed Conceptual Model and Research Agenda

Precision medicine, nutrition and behavioral interventions are attempting to move beyond the specification of therapies applied to groups, since some people benefit, some do not and some are harmed by the same therapy. Instead, precision therapies are attempting to employ diverse sets of data to individualize or tailor interventions to optimize the benefits for the receiving individuals. The benefits to be achieved are mostly in the distant future, but the research needs to start now. While precision pediatric nutrition will combine diverse demographic, behavioral and biological variables to specify the optimal foods a child should eat to optimize health, precision food parenting will combine diverse parent and child psychosocial and related variables to identify the optimal parenting practices to help a specific child accept and consume the precision nutrition specified foods. This paper presents a conceptual overview and hypothetical model of factors we believe are needed to operationalize precision food parenting and a proposed research agenda to better understand the many specified relationships, how they change over the age of the child, and how to operationalize them to encourage food parenting practices most likely to be effective at promoting healthy child food choices.

Social organization in ungulates: Revisiting Jarman's hypotheses

Ungulates (antelopes, deer and relatives) have some of the most diverse social systems among mammals. To understand the evolution of ungulate social organization, Jarman (1974) proposed an ecological scenario of how distribution of resources, habitat and feeding style may have influenced social organization. Although Jarman's scenario makes intuitive sense and remains a textbook example of social evolution, it has not been scrutinized using modern phylogenetic comparative methods. Here we use 230 ungulate species from ten families to test Jarman's hypotheses using phylogenetic analyses. Consistent with Jarman's proposition, both habitat and feeding style predict group size, since grazing ungulates typically live in open habitats and form large herds. Group size, in turn, has a knock-on effect on mating systems and sexual size dimorphism, since ungulates that live in large herds exhibit polygamy and extensive sexual size dimorphism. Phylogenetic confirmatory path analyses suggest that evolutionary changes in habitat type, feeding style and body size directly (or indirectly) induce shifts in social organization. Taken together, these phylogenetic comparative analyses confirm Jarman's conjectures, although they also uncover novel relationships between ecology and social organization. Further studies are needed to explore the relevance of Jarman (1974) scenario for mammals beyond ungulates.

Starting Early Program Impacts on Feeding at Infant 10 Months Age: A Randomized Controlled Trial

Background: Disparities in obesity-promoting feeding patterns begin in pregnancy and infancy, underscoring the need for early primary prevention in high-risk groups. We sought to determine the impact of a primary care-based child obesity prevention intervention beginning during pregnancy on maternal infant feeding practices, knowledge, and styles at 10 months in low-income Hispanic families. Methods: The Starting Early Program (StEP) randomized controlled trial enrolled pregnant women at a third trimester visit. Women (n = 533) were randomized to standard care or an intervention with prenatal/postpartum individual nutrition counseling and nutrition and parenting support groups coordinated with pediatric visits. Feeding practices (breastfeeding, family meals, juice, and cereal in the bottle) were assessed using questions from the Infant Feeding Practices Study II. Feeding styles were assessed using the Infant Feeding Style Questionnaire. We analyzed impacts on feeding practices, knowledge, and styles using regression analyses adjusting for covariates. Results: Four hundred twelve mothers completed 10-month assessments. Intervention mothers were more likely to give breast milk as the only milk source [adjusted odds ratio (AOR) 1.65, 95% confidence interval (CI) 1.06-2.58] and have daily family meals (AOR 1.91, 95% CI 1.19-3.05), and less likely to give juice (AOR 0.60, 95% CI 0.39-0.92) or cereal in the bottle (AOR 0.54, 95% CI 0.30-0.97) compared to controls. Intervention mothers were more likely to exhibit lower pressuring, indulgent and laissez-faire feeding styles, and to have higher knowledge. Attending a greater number of group sessions increased intervention impacts. Conclusions: StEP led to reduced obesity-promoting feeding practices and styles, and increased knowledge and provides great potential for population-scalability.

Dissimilarities across age groups in the associations between complementary feeding practices and child growth: Evidence from rural Togo

Adequate complementary feeding (CF) practices are essential for achieving optimal growth but challenging to measure comprehensively. This paper describes CF practices in 2,034 children aged 6-23 months and investigates their relationships with length-for-age z-score (LAZ) and stunting, using cross-sectional data collected from May to July 2014 in rural Northern Togo. The World Health Organization infant and young child feeding indicators were computed, along with ancillary indicators on feeding style and timing of introduction of complementary foods. The associations between those indicators and children's LAZ and stunting were assessed using linear and logistic regressions after stratification by age group and adjustment for children, maternal, and household characteristics. CF practices were suboptimal, and their associations with child's growth varied across indicators and age groups. In children aged 6-11 months, reaching the minimum dietary diversity and the minimum acceptable diet was associated with higher LAZ (p < .05). In 18- to 23-month-old children, only the consumption of iron-rich food was associated with both LAZ (p = .02) and stunting (p = .05). The late introduction of family foods was associated with higher odds of being stunted and lower LAZ in children aged 12-17 months (p < .001). The untimely introduction of porridge was associated with higher odds of stunting in children aged 9-23 months (p < .05). Unexpectedly, helping the child to eat was negatively associated with linear growth in all age groups. These findings nurture the ongoing process of review of the World Health Organization infant and young child feeding indicators showing that, in their current version, they hardly capture the links between CF and child's growth at different ages.

Indirect Effects of Food Insecurity on Body Mass Index Through Feeding Style and Dietary Quality Among Low-Income Hispanic Preschoolers

OBJECTIVE

To investigate whether food insecurity affects child body mass index (BMI) through parental feeding demandingness and/or responsiveness and dietary quality 18 months later among low-income Hispanic preschoolers.

DESIGN

Secondary analysis of data at baseline and 18 months afterward.

SETTING

Houston, TX.

PARTICIPANTS

Hispanic parent-preschooler dyads (n = 137).

VARIABLES

Food insecurity (6-item Household Food Security Survey), child BMI (BMI z-score), child dietary quality (Healthy Eating Index), and parental feeding demandingness and responsiveness (Caregiver's Feeding Style Questionnaire).

ANALYSIS

Ordinary least-squares regression models and 95% bootstrapped confidence intervals (CIs) to estimate effects.

RESULTS

Controlling for baseline child BMI, maternal acculturation, and maternal BMI, total indirect effects of food insecurity on child BMI through feeding demandingness, responsiveness, and subsequent child dietary quality were estimated to be 0.001 (95% bias-controlled bootstrap CI, -0.01 to 0.01). Confidence intervals for all indirect pathways straddled 0. As food insecurity worsened, child dietary quality 18 months after baseline improved (c = 1.06; 95% CI, 0.41-1.71).

CONCLUSIONS AND IMPLICATIONS

Food insecurity had no influence on child BMI through feeding demandingness/responsiveness and/or child dietary quality. Additional research is needed to examine why food insecurity had a protective effect on dietary quality 18 months later. This finding suggests the adoption of coping mechanisms.

Caregiver feeding practices and child weight outcomes: a systematic review

BACKGROUND

As part of the USDA-Department of Health and Human Services Pregnancy and Birth to 24 Months Project, we conducted systematic reviews (SRs) on topics important for health and nutrition of young children.

OBJECTIVES

The purpose of the present SR was to examine the relation between caregiver feeding practices in children from birth to 24 mo and child weight gain, size, and body composition.

METHODS

A search of articles published from January 1980 to January 2017 in 4 databases identified 8739 references. Nutrition Evidence Systematic Review (NESR) analysts used the Nutrition Evidence Library Risk of Bias Assessment Tool to assess potential bias in the studies, and a Technical Expert Collaborative graded the body of evidence using the NESR grading rubric.

RESULTS

Twenty-seven articles were included in this review (8 controlled trials, 19 longitudinal cohort studies). Moderate evidence from randomized controlled trials suggests that providing responsive feeding guidance to teach mothers to recognize and respond appropriately to children's hunger and satiety cues can lead to "normal" weight gain and/or "normal" weight status in children aged ≤2 y compared with children whose mothers did not receive responsive feeding guidance. Moderate evidence from longitudinal cohort studies indicates an association between maternal feeding practices and the child's weight status and/or weight gain, but the direction of effect has not been adequately studied. Restrictive feeding practices are associated with increased weight gain and higher weight status, and pressuring feeding practices are associated with decreased weight gain and lower weight status. Evidence suggests that a mother's feeding practices are related to concerns about her child's body weight.

CONCLUSIONS

This review highlights the importance of the interaction between caregivers and infants and toddlers related to child feeding practices on children's weight outcomes. Research is needed on more diverse populations with consistent methodological app-roaches and objective measures.

Parental feeding style changes the relationships between children's food preferences and food parenting practices: The case for comprehensive food parenting interventions by pediatric healthcare professionals

PURPOSE

To determine if parental feeding styles (emotional environment of the meal) moderate the relationship between food parenting practices (goal-directed behaviors) and children's preferences for fruits, vegetables, or high fat/sugar foods.

DESIGN AND METHODS

This cross-sectional descriptive study recruited parents (n = 108) of preschool age children. The parents completed several questionnaires. Linear regressions were used to assess the relationship between food parenting practices and children's food preferences as moderated by feeding style, with the authoritative feeding style serving as the reference.

RESULTS

Parental feeding styles were found to be moderators between several food parenting practices and child food preferences. When compared with parents with the authoritative feeding style (high demands, responds to child's needs), children like vegetables significantly less if indulgent (low demands, responds to child's needs) parents allow children to control their own eating, or authoritarian (high demands, does not respond to child's needs), or uninvolved (low demands, does not respond to child's needs) parents provide a healthy food environment. The authoritative style was not always preferential. For example, children of uninvolved parents who used food as a reward liked vegetables significantly more than children of parents who had the authoritative feeding style who also used food as a reward. In addition, children of authoritarian parents who modeled healthy eating liked foods high in fat and/or sugar significantly less than children of authoritative parents.

PRACTICE IMPLICATIONS

When discussing child diet quality with parents, pediatric nurses should educate parents on both food parenting practices and feeding style, or the meal's emotional climate, as children experience both of these during mealtime interactions. In addition, for educational efforts, it may be advantageous to tailor interventions based upon the parent's feeding style.

Prevalence of Anemia and Its Associated Risk Factors Among 6-Months-Old Infants in Beijing

Objective: The worldwide prevalence of anemia is ~24.8%. Iron deficiency anemia is common in children and women and associated with sensory, motor, cognitive, language, and socioemotional deficits. Therefore, detection and early intervention strategies for anemia in infants are urgently needed. To prevent the occurrence of iron deficiency anemia, we aimed to identify risk factors associated with anemia in infants. Methods: This investigation involved a cross-sectional study of 6-months-old infants discharged between April 2014 and September 2017 from Peking University First Hospital. We assessed birth information, maternal age, and maternal educational level as well as data on feeding style, complementary foods and primary caregivers. The infants were assessed with the Denver Developmental Screening Test (DDST). Results: A total of 1,127 6-months-old infants were enrolled at the hospital. We found that the prevalence of anemia among infants in Beijing was ~11.8%. Premature infants had a higher rate of anemia than full-term infants (χ² = 40.103, P < 0.001). Infants born in autumn or winter were at an elevated risk of developing anemia (χ² = 22.949, P < 0.001). Birth weight had no effect on the rate of anemia in infants (χ² = 0.023, P = 0.568). Infants who were exclusively breastfeeding had higher anemia rates than those who were fed formula (χ² = 38.466, P < 0.001). Infants whose caregivers added no complementary foods had higher anemia rates (24.7%) than those whose caregivers added more than two kinds of complementary food (8.2%). The type of caregiver had no effect on the anemia rate in infants (χ² = 0.031, P = 1.000). Conclusions: The following factors resulted in a higher prevalence of anemia in our study a gestational age at birth of <37 weeks, exclusive breastfeeding, a lack of supplementation with complementary foods and a spring birth date. No significant differences in DDST pass rates were evident between infants with and without anemia.

Relationship between maternal depression symptoms and child weight outcomes in Latino farmworker families

This study sought to characterize depressive symptoms among mothers in Latino farmworker families, determine if maternal depression increases children's risk of obesity, and ascertain whether relevant risk factors such as physical activity, diet, and feeding style mediate this relationship. Mothers from 248 families completed the 10-item Center for Epidemiologic Studies Depression Scale 9 times over a 2-year period. Four distinct patterns were used to describe mothers: few symptoms, moderate episodic symptoms, severe episodic symptoms, and chronic symptoms. Approximately two-thirds of women experienced moderate symptoms of depression at least once. Children of mothers fitting each pattern were compared. At the end of the study, children of mothers with severe episodic and chronic symptoms were significantly more likely to be overweight and obese than children of mothers with few symptoms (p < .05). After controlling for covariates, differences in weight status for children of mothers with severe episodic symptoms remained significant. Children of mothers with either moderate episodic or chronic symptoms were fed in a less responsive fashion (p < .05), and children of chronically symptomatic mothers had lower diet quality (p < .01). Although nonresponsive feeding has been linked to childhood obesity, in this analysis, feeding style did not mediate the relationship between maternal depression and diet quality. Elevated levels of depressive symptoms are common in this population, and those symptoms, especially when severe or chronic in nature, may increase children's risk of obesity. Additional research is needed to characterize the pathways through which maternal depression influences children's weight.

Parental Feeding Style and Pediatric Obesity in Latino Families

INTRODUCTION

Pediatric obesity has become an epidemic in the United States. Previous research has shown that parenting factors related to feeding style affect child weight and that Latino families are especially at risk for pediatric obesity. The goal of the current study was to evaluate the relationship between parental feeding style and child body mass index (BMI) in Latino families.

METHOD

Latino parents of children between the ages of 2 and 8 ( N = 124) completed a survey on parental feeding styles, acculturation, and demographics. The outcome variable was child BMI.

RESULTS

Among respondents, 89% were mothers, 72% were overweight or obese, and 40% reported an indulgent feeding style. Children had a mean age of 59 months ( SD = 23.8) and a mean BMI z score of 0.77 ( SD = 1.14). A demanding parental feeding style was associated with lower child BMI z score, r = -.179, p < .05, and higher acculturation level, r = .213, p < .05.

CONCLUSIONS

Findings from the current study can be used to inform health care practitioners of the need to use culturally sensitive interventions that consider parents' feeding behaviors. Future research is warranted in the area of ethnic variations of parenting and how these affect feeding and obesity in this highly vulnerable population.
