Parent-Child Interaction, Self-Regulation, and Obesity Prevention in Early Childhood

Moderating effects of demographic characteristics on the relationship between parenting practices and energy balance related behaviors of Chinese preschoolers

Background

Early establishment of energy balance related behaviors (EBRBs) may be effective in combating unhealthy lifestyle in preschoolers. Parents are responsible for cultivating preschoolers' EBRBs directly through parenting practices. Although investigating the impact of various parenting practices on preschoolers' EBRBs is crucial to determine which practices should be recommended to parents to help reverse childhood unhealthy lifestyle, it is important to assess whether these effects of parenting practices on preschoolers' EBRBs would be similar across different groups of preschoolers, necessitating research into the moderating effects of demographic characteristics.

Methods

Baseline dataset was utilized from an electronic health intervention study of Chinese 3-6-year-old preschoolers. Preschoolers' PA and sleep duration and quality were objectively examined using wGT3X ActiGraph accelerometer. Data related to parents and preschoolers' eating behaviors and sleep problems were subjectively assessed using parent-reported questionnaires. The PROCESS macro version 4.2 was used to perform moderation analysis. When the interaction revealed a p-value of less than 0.05 and the 95% confidence interval did not include 0, the conditional effects of the focal predictor at various levels of the moderator were further examined (p < 0.05) to investigate how the relationship between parenting practices and preschoolers' EBRBs varied with different moderator levels.

Results

Married parents exhibited the desired outcomes in the relationship between parenting practices and their preschoolers' EBRBs. In contrast, divorced/separated parents showed unfavorable results in this relationship. The association between the parents' and preschoolers' BMI varied depending on parents' socioeconomic status, the preschoolers' age, and the number of children in the household. The preschoolers' age showed different moderating trend on the relationship between parents' PA and preschoolers' sedentary behaviors as well as the association of eating-related PSE with preschoolers' eating behaviors. The mechanisms linking the parents' PSE to the preschoolers' PA, sedentary behaviors, and sleep duration were influenced by the preschoolers' gender and the number of children in the household.

Conclusion

The potential parental influence warrants further investigation with the consideration that the relationship between parenting practices and preschoolers' EBRBs varied across different group of children.

Play With Me: Effects of a shared activities parenting intervention on parenting and relative reinforcing value of food

This pilot randomized controlled trial evaluated impacts of a novel shared activities intervention designed to promote positive parent-child interactions, which may function as an alternative reinforcer to food. The 4-week, at-home Play With Me intervention combines didactic parenting videos and play kits with materials for parent-child activities to practice skills. Aims of the present study were to examine the intervention's acceptability and its effects on parenting and the relative reinforcing value (RRV) of food versus parent-child activity at post-intervention. Thirty-two parents of 4-to-5-year-old children at risk for obesity were randomly assigned to the intervention or a waitlist control group. The intervention was well-liked by parents and feasible. Intervention parents reported more parenting structure and demonstrated higher observed sensitive parenting than controls at post; the latter finding was driven by greater parent positive mood, warmth, positive reinforcement, and relationship quality, with large effect sizes. There were no effects on the RRV of food. Inconsistent with hypotheses, there were trends toward control group parents reporting more parenting satisfaction and efficacy at post. Possible explanations are discussed. Results suggest Play With Me shows promise as an effective and acceptable intervention to promote positive parenting. Further research is needed to examine these effects and their implications for socioemotional development and health in a larger, more diverse sample over a longer time frame.

Screen time and obesity prevalence in adolescents: an isotemporal substitution analysis

BACKGROUND

We examined the associations between screen time and adolescent obesity and the associations of reallocating screen time to other activities using isotemporal substitution models. Understanding the association between screen time and obesity may provide additional insights into effective obesity prevention strategies in adolescents.

METHODS

We conducted a cross-sectional analysis of 5,180 adolescents (4th and 7th grade students) from the Korean Children and Youth Panel Survey 2018. Participants reported their height, weight, and average time spent watching television, using computer, using smartphone, and other after-school activities. Obesity was defined as BMI-for-age and -sex ≥ 95th percentile based on the 2017 Korean National Growth Charts. We performed multivariable logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the associations between screen time and obesity prevalence, adjusting for potential confounders.

RESULTS

Prolonged smartphone use (≥ 180 vs. <60 m/d: OR [95% CI] = 2.75 [2.06, 3.68]) was associated with a higher obesity prevalence. Television watching (≥ 120 vs. <60 min/d) was positively associated with obesity prevalence among 4th grade students (2.09 [1.51, 2.89]) but the association was not observed among 7th grade students (0.97 [0.63, 1.49]). One-hour increments of any non-screen time activities, with a simultaneous 1-hour decrease in combined screen time, were associated with a lower obesity prevalence (physical activity: 0.75 [0.65, 0.85]; sleeping: 0.69 [0.62, 0.78]; hanging out with friends: 0.80 [0.71, 0.89]; reading: 0.82 [0.69, 0.97]; studying: 0.84 [0.78, 0.90]; chatting with parents: 0.89 [0.88, 0.98]).

CONCLUSIONS

Our data suggest that public health strategies that reduce screen time and increase time for non-screen time activities, such as physical activity, may be effective in lowering adolescent obesity prevalence.

Provider Perspectives on Techniques for Healthy Eating Promotion and Dietary Behavior Change in Caregiver-Child Dyads

Child lifestyle behaviors are influenced by their caregivers. Targeting the caregiver-child relationship can establish healthy habits, especially healthful eating patterns, in both the caregiver and child. The purpose of this study was to identify the context for addressing strategies used to establish nutritious eating for the caregiver and child taken together as a unit (e.g., the caregiver-child dyad), through the perspectives of nutrition-promoting professionals. We performed purposive sampling of professionals who address healthful nutrition. Semi-structured qualitative interviews were conducted to elicit perspectives on caregiver-child eating dynamics and techniques to produce dietary behavior change. Data were coded through the constant comparative method, and subthemes and themes were identified by grouping similar codes and excerpts. We identified four themes relevant to dyadic dietary behavior change: (1) factors to consider when approaching nutrition such as family dynamics, (2) dyad-specific strategies for dietary behavior change, (3) patient-centered approaches professionals implement in interactions with the dyad, and (4) time as a barrier to dietary behavior change. In conclusion, study is novel in eliciting the perspectives of professionals across multiple settings to provide a context for dyadic dietary behavior change. Future studies can focus on developing training for lifestyle medicine professionals to approach dyad-specific behavior modification.

Attachment style to body dissatisfaction, restrained eating, and disordered eating in adolescent girls: Differential weight communication mediators

Body dissatisfaction and eating behaviors are disproportionately elevated amongst adolescent girls. Family relationships represent a context in which adolescent girls' body image issues emerge. Thus, we integrated attachment and confirmation theories to examine whether weight related supportive messages (i.e., acceptance and challenge) mediated the relationship between attachment style (i.e., anxiety and avoidance) and body image outcomes (i.e., body dissatisfaction (BD), restrained eating (RE), and disordered eating (DE)). Acceptance refers to weight related support that is characterized by warmth and accepting messages; challenge refers to weight related support that is characterized by instrumental assistance and problem-solving messages. A sample of 106 adolescent girls, ages 11 to 21, completed self-report measures on attachment (Relationship Structures Questionnaire), acceptance and challenge (weight related Parental Behavior Questionnaire), body dissatisfaction (Eating Disorders Inventory), and eating behaviors (Dutch Eating Behavior Questionnaire; Eating Disorder Diagnostic Scale). Attachment anxiety directly related to all body image outcomes, whereas attachment avoidance only directly related to RE. Attachment avoidance only related to BD and DE indirectly through perceived acceptance. Those with high anxiety endorsed lower perceived challenge, whereas avoidant individuals endorsed lower perceived acceptance and challenge. We concluded that attachment dimension characteristics to be either hyperactivated regarding relationships (i.e., anxiety), or deactivated and distant (i.e., avoidance), are associated with how individuals perceive support, and in turn, are related to body image and eating behavior outcomes. Further, we clarify the differential roles of acceptance and challenge. Although both supportive, acceptance encompasses a layer of warmth that is more meaningful in body image, particularly for avoidantly attached individuals. By integrating qualities of attachment and supportive weight communication, we reveal that potential pathways of attachment to body image and eating behaviors.

Maternal depressive symptom trajectories and associations with child feeding

BACKGROUND

Responsive feeding, when caregivers attend to children's signals of hunger and satiation and respond in an emotionally supportive and developmentally appropriate way, is associated with the development of healthy eating behaviors, improved diet quality, and healthy weight status for children. However, gaps in the literature remain on how factors, such as maternal depressive symptoms and child temperament, influence feeding interactions.

METHODS

This longitudinal secondary data analysis explored the association between maternal depressive symptom trajectory and child temperament with maternal feeding practices in women with obesity who participated in a prenatal lifestyle intervention trial. Mothers self-reported depressive symptoms at baseline, 35 weeks gestation, and 6, 12, and 18 months postpartum. At 18- and 24-months postpartum, mothers completed self-reported assessments of feeding practices and child temperament and completed in-home video-recorded meals with their child, coded using the Responsiveness to Child Feeding Cues Scale. We used group-based trajectory modeling to identify distinct trajectories of depressive symptoms and generalized regressions to assess the association between symptom trajectory group and feeding. We also explored interactions between depressive symptoms and child temperament.

RESULTS

Three distinct trajectories of depressive symptoms were identified: No-Minimal and Decreasing, Mild-Moderate and Stable, and Moderate-Severe and Stable. At 18-months, when compared to the No-Minimal and Decreasing group, membership in the Moderate-Severe and Stable group was associated with higher observed responsiveness to child satiation cues ([Formula: see text] =2.3, 95%CI = 0.2, 4.4) and lower self-reported pressure to eat ([Formula: see text]=-0.4, 95%CI= -0.7, 0.0). When compared to the No-Minimal and Decreasing group, membership in the Mild-Moderate and Stable group was associated with higher self-reported restriction ([Formula: see text] =0.4, 95%CI = 0.0,0.7). The associations between trajectory group membership and feeding practices did not reach statistical significance at 24 months. Associations between depressive symptoms and restriction were moderated by child effortful control at 18 months [Formula: see text]) and surgency at 24 months [Formula: see text]).

CONCLUSION

A Moderate-Severe and Stable depressive symptom trajectory was associated with more responsive feeding practices and a Mild-Moderate and Stable trajectory was associated with higher restrictive feeding. Preliminary evidence suggests that depressive symptoms impact mothers' ability to match their use of restriction to the temperamental needs of their child.

The temporal stability of maternal parenting style and child feeding practices: A six-wave longitudinal study

Although parenting styles and child feeding practices are conceptualized as distal, static predictors of child eating and weight outcomes, few studies have examined the temporal stability (i.e., change over time) of these parenting measures. Also, parental characteristics, such as mental health or socio-demographics, may make it more or less difficult to sustain consistent parenting behavior. This study examined the temporal stability of parenting styles and child feeding practices and the association between temporal stability indices with maternal sociodemographic and mental health characteristics. The analytic sample included 161 ethnically diverse mothers enrolled in a six-wave bi-annual longitudinal study. During each wave, mothers reported on their parenting styles and child feeding practices using validated self-report questionnaires. Temporal stability indices for parenting styles were moderate for authoritative (ICC = 0.57) and authoritarian (ICC = 0.70) styles, yet high for permissive (ICC = 0.78) styles. Temporal stability scores for child feeding practices were low for discipline (ICC = 0.33), limit setting (ICC = 0.33), monitoring (ICC = 0.36), and pressure to eat (ICC = 0.34); however, restriction (ICC = 0.53) and role modeling of healthy eating were moderate (ICC = 0.73). Greater income and education status were positively associated with stability in authoritative, authoritarian, and permissive parenting styles, as well as with limit setting, monitoring, role modeling of healthy eating, and pressure to eat feeding practices. Higher anxiety and depressive symptoms and lower self-esteem were negatively associated with permissive parenting styles and role modeling of healthy eating. Findings show that maternal parenting styles and child feeding practices fluctuate over time, and sociodemographic and mental health characteristics are related to stability of some of these parenting styles and behaviors.

The relationships between screen exposure, parent-child interactions and comprehension in 8-month-old infants: The mediating role of shared viewing and parent-child conversation

OBJECTIVE

To explore the relationships between screen exposure, parent-child interactions and comprehension in 8-month-old infants, and to examine whether shared viewing and parent-child conversation during screen exposure may play mediating role in that relationships.

METHODS

The sample included 437 infants aged 8 months from the Children's Health Department of Guiyang Maternal and Child Health Hospital during January 2022 to February 2023. The use of electronic screen devices was assessed using a screen exposure questionnaire. The Brigance Parent-child interactions Scale was used to assess parent-child interactions and the Putonghua Communicative Development Inventory (PCDI) scale was used to assess infants' word comprehension.

RESULTS

48.7% of infants were found to be using screens 1-2 days per week. There was a significant difference (p < 0.05) in the PCDI-comprehension scores of screen-exposed infants compared to non-screen-exposed infants. Shared viewing and parent-child conversation during screen exposure were positively associated with parent-child interactions (p < 0.05). Mediation analysis revealed that parent-child conversation fully mediated between screen exposure and PCDI-comprehension, but partially mediated between parent-child interactions and PCDI-comprehension.

CONCLUSIONS

Shared viewing and parent-child conversation during screen exposure may mediate between screen exposure and comprehension development. Shared viewing, parent-child conversation and parent-child interactions may be protective factors for screen exposure in comprehension development. Suggests that parents should accompany and communicate with their children when they use electronic screen devices to reduce the negative impact of screen exposure on children's comprehension.

Maternal control and eating styles in children: The mediating role of emotion differentiation

Introduction: Theoretical accounts and empirical research suggest that mother-child interactions significantly influence the child's eating styles (emotional, external, and restrained eating). However, little or no research has explored the association between maternal psychological control and eating styles and whether other mechanisms may be involved in such association. To address this shortcoming, the present study aimed to investigate the mediating role of difficulties in differentiating emotions between maternal control and eating styles.Methods: Participants were 324 elementary school children (Girls = 172, 53.1%) aged between 8 and 11 years (Mage = 9.13, SD = .89) assessed through self-report measures. Parents provided information about weight and height.Results: Path analysis model showed an acceptable fit to the data (χ2 (3) = 3.966, p = .256; RMSEA = .032; CFI = .990; TLI = .911; SRMR = .018). Difficulties in differentiating emotions significantly mediated the relationship between maternal control and emotional eating (β = -.071, 95%CI [-.094, -.052]; p < .001). The model was invariant across genders.Conclusions: Our findings support the importance of dyadic interaction in enhancing the risk for dysfunctional eating style during infancy, showing that emotion differentiation deficits may be particularly salient in such relationship. Clinical and practical implications of these findings are discussed.

Complementary feeding approach and maternal responsiveness in 8- and 12-month-old Italian infants: A longitudinal study

In Western countries, infants are usually introduced to solids through spoon-fed puréed foods (parent-led weaning, PLW). However, an alternative approach known as "baby-led weaning" (BLW), in which infants usually participate in family meals and eat independently, is becoming increasingly popular. We investigated the relationship between the type of complementary feeding approach and maternal responsiveness to infant feeding cues in a longitudinal sample of 178 infants observed at 8 and 12 months. Mothers reported the complementary feeding method used and, from video-recorded meals, we coded the proportion of time infants self-fed and rated maternal responsiveness by means of the Responsiveness to Child Feeding Cues Scale (Hodges et al., 2013). Responsiveness to infant receptiveness and fullness cues were significantly correlated at 8 months, but not at 12 months, when unresponsiveness decreased for receptiveness but remained stable for fullness cues. Thus, as infants got older, mothers were increasingly tuned in to their receptiveness cues. However, we did not observe the same pattern for fullness cues, perhaps because mothers were concerned that their infants did not eat enough. Moreover, at both time points, mothers were more responsive to infants' receptiveness than fullness cues, possibly due to an evolutionary drive to protect infants from starvation. Finally, responsiveness to fullness, but not responsiveness to receptiveness, was positively related to the proportion of infant self-feeding, but there were no significant differences in responsiveness depending on the self-reported complementary feeding approach. Thus, a weaning style that emphasizes independent feeding, regardless of whether this is labeled as BLW, may promote more infant-centered maternal responses at the end of the meal, with potential implications for promoting infant self-regulation not only at mealtimes, but also in other domains.

Variability in parenting behaviors during play and during mealtimes with toddlers

Few empirical studies have explored variability in parenting behaviors observed in a mealtime setting as well as in a play setting with young children. We analyzed data from 282 parent-toddler dyads who participated in the Play & Grow study in the United States in 2017-2019. Parent-child interactions were video-recorded during play in the laboratory when the child was 18 months old and then during mealtime in the home 6-months later. Standardized coding procedures were used to rate parenting behaviors (sensitivity, cognitive stimulation, positive regard, detachment, intrusive control, negative regard). We describe correlations and differences and variability in parenting behavior between the two assessments and relative to child sex, gestational age, parent education level, household composition, and household income. Detachment was lower on average during play at 18 months compared to during mealtime at 24 months (Cohen's d=-.40), and the other five parenting behaviors were greater on average during play than during mealtime (d=.18-.43) Sociodemographic characteristics were unrelated to the magnitude of individual differences across contexts in any of the parenting behaviors. Implications for research on associations between parent-child interactions and risk for childhood obesity are discussed.

Associations between behavioral self-regulation and external food cue responsiveness (EFCR) in preschool-age children and evidence of modification by parenting style

Decreased behavioral regulation is hypothesized to be a risk factor for excess weight gain among children, possibly via reduced appetite-specific regulation. Little research has specifically focused on behavioral regulation and food cue responsiveness, a conditioned precursor to eating, at a young age. This study examined the association between behavioral regulation and external food cue responsiveness among preschool-age children and explored if a more structured parenting style moderated that association. Baseline data from a prospective study on media use among preschool-age children (n = 83) in Northern New England were used. Parents reported on three domains of children's behavioral regulation (attentional focusing, inhibitory control, and emotional self-regulation), the children's external food cue responsiveness (EFCR), and their parenting styles (authoritative and permissive) via validated questionnaires. Mean age among children was 4.31 (SD 0.91) years, 57% of children were male, 89% were non-Hispanic white, and 26.2% had overweight or obesity. In a series of adjusted linear regression models, lower attentional focusing (standardized β, βs = -0.35, p = 0.001), inhibitory control (βs = -0.30, p = 0.008), and emotional self-regulation (standardized beta, βs = -0.38, p < 0.001) were each significantly associated with greater EFCR. In exploratory analyses, a more structured parenting style (more authoritative or less permissive) mitigated the associations between inhibitory control and EFCR (Bonferroni-adjusted p-interaction < 0.017). Findings support that lower attentional focusing, inhibitory control, and emotional self-regulation relate to greater ECFR in preschool-age children. The association between inhibitory control and EFCR may be modified by parenting style. Further research is needed to understand if children's responsiveness to external food cues may account for reported associations between lower behavioral regulation and adiposity gain over time.

The relationship between family diet consumption, family environment, parent anxiety and nutrition status children during the COVID-19 pandemic: a longitudinal study

Background

The COVID-19 pandemic has exacerbated the trends of childhood overweight, obesity, and malnutrition, as well as increased psychological stress and family conflicts among family members. It is important to explore the relationship between changes in the family environment during the COVID-19 on child nutrition.

Objective

This study aims to analyze the nutritional status of Chinese children during the COVID-19 pandemic and its relationship with family diet, family environment, and parental anxiety, in order to provide evidence for further interventions in children's nutritional status.

Method

This study included 7,645 primary and secondary school students and their parents from five schools in Chengdu, China. Chi-square tests were used to analyze the categorical variables of children's malnutrition, overweight, obesity, and parental anxiety. T-tests were used to assess changes in the continuous variable of family environment between two rounds of follow-up surveys. Multiple logistic regression analysis was employed to examine the impact of changes in family diet during the COVID-19 pandemic on children's nutritional status. Generalized estimating equations were used to analyze the effects of family environment and parental anxiety on childhood obesity.

Result

The prevalence of malnutrition and obesity decreased from 11.64% and 11.60% in wave 1 to 4.96% and 10.50% in wave 2, and the rate of overweight increased from 13.11% in wave 1 to 13.73% in wave 2. Children whose families reduced consumption of staple foods during the COVID-19 were more likely to be frail, and families increased consumption of sugary drinks, take-out or meal delivery services, living in towns, family environmental barriers, and parental anxiety were risk factors for overweight obesity. Mother's education level in middle and high school and low age were protective factors for overweight obesity.

Conclusion

The physical environment of the family, the emotions of family members, and children's perceptions of the family's soft environment can influence children's eating behaviors, children's nutritional intake, and malnutrition and obesity in children under public health emergencies, and family-based dietary interventions may be effective. Parents can increase consumption of healthy foods and improve the family environment, which improve their growth.

The effects of a music enrichment program on parent-infant interactions during mealtime: A randomized controlled trial

BACKGROUND

Parent-child interactions are linked to childhood obesity. Music enrichment programs enhance parent-child interactions and may be a strategy for early childhood obesity prevention.

OBJECTIVE

We implemented a 2-year randomized, controlled trial to assess the effects of a music enrichment program (music, n = 45) vs. active play date control (control, n = 45) on parent-child interactional quality and infant weight status.

METHODS

Typically developing infants aged 9-to 15-months were enrolled with a primary caregiver in the Music Together ® or a play date program. Participants attended once per week group meetings for 12 months and once per month group meetings for an additional 12 months. Parent-child interaction was measured using the Parent Child Early Relational Assessment (PCERA) at baseline, month 6, 12, and 24. We used a modified intent-to-treat mixed model regression to test group differences in parent-child interactions and Weight for length z-score (zWFL) growth trajectories were modeled.

RESULTS

There were significant differential group changes across time for negative affect during feeding (group*month; p = 0.02) in that those parents in the music group significantly decreased their negative affect score compared with the control group from baseline to month 12 (music change = -0.279 ± 0.129; control change = +0.254 ± 0.131.; p = 0.00). Additionally, we also observed significant differential group changes across time for parent intrusiveness during feeding (group*month; p = 0.04) in that those parents in the music group significantly decreased their intrusiveness score compared with the control group from month 6 to month 12 (music change = -0.209 ± 0.121; control change = 0.326 ± 0.141; p = 0.01). We did not find a significant association between any of the changes in parental negative affect and intrusiveness with child zWFL trajectories.

CONCLUSION

Participating in a music enrichment program from an early age may promote positive parent-child interactions during feeding, although this improvement in the quality of parent-child interactions during feeding was not associated with weight gain trajectories.

Long- and Short-Term High-Intensity Interval Training on Lipid Profile and Cardiovascular Disorders in Obese Male Adolescents

This study investigated the effects of short-term and long-term periods (8 and 16 weeks) of high-intensity interval training (HIIT) on cardiovascular components, blood lipids, and 6-min walking test performance in obese young boys (age = 16.2 ± 0.7) with >34% body fat. The participants were split into two groups: severe obesity (SOG; n = 17) and moderate obesity (MOG; n = 16). All participants performed on a cycle ergometer for 16 weeks (3 times per week) of HIIT at 100% peak power output at the ventilatory threshold and recovered at 50% of peak power. Except for BMI, both groups improved all body composition measures after 16 weeks, with a higher percentage of change (Δ) in SOG. The 6-min walking test increased in both groups (p < 0.001). Furthermore, cardiovascular variables, blood lactate concentration at rest and after 5-min post-exercise, blood lipids, and insulin concentrations improved significantly in both groups. After 16 weeks, MOG significantly improved in HR_peak, blood glucose concentration, and rating of perceived exertion (RPE), but the percentage of change (Δ) was higher in SOG for all the other variables. SOG showed a higher (Δ) waist-to-hip ratio, maximum heart rate, resting heart rate, systolic blood pressure, blood lactate at 5-min post-exercise, and triglyceride concentrations after 8 and 16 weeks of training. In conclusion, a long-term HIIT program appears to be an appropriate training approach for obese boys with extra body fat. However, considering the RPE values, short-duration training sessions should be planned.

I-PREGNO - prevention of unhealthy weight gain and psychosocial stress in families during pregnancy and postpartum using an mHealth enhanced intervention: a study protocol of two cluster randomized controlled trials

BACKGROUND

The transition to parenthood represents a critical life period with psychosocial, and behavioral changes and challenges for parents. This often increases stress and leads to unhealthy weight gain in families, especially in psychosocially burdened families. Although universal and selective prevention programs are offered to families, specific support often fails to reach psychosocially burdened families. Digital technologies are a chance to overcome this problem by enabling a low-threshold access for parents in need. However, there is currently a lack of smartphone-based interventions that are tailored to the needs of psychosocially burdened families.

AIMS

The research project I-PREGNO aims to develop and evaluate a self-guided, smartphone-based intervention in combination with face-to-face counseling delivered by healthcare professionals for the prevention of unhealthy weight gain and psychosocial problems. The intervention is specifically tailored to the needs of psychosocially burdened families during the pregnancy and postpartum period.

METHODS

In two cluster randomized controlled trials in Germany and Austria (N = 400) psychosocially burdened families will be recruited and randomized to i) treatment as usual (TAU), or ii) I-PREGNO intervention (self-guided I-PREGNO app with counseling sessions) and TAU. We expect higher acceptance and better outcomes on parental weight gain and psychosocial stress in the intervention group.

DISCUSSION

The intervention offers a low cost and low-threshold intervention and considers the life situation of psychosocially burdened families who are a neglected group in traditional prevention programs. After positive evaluation, the intervention may easily be implemented in existing perinatal care structures in European countries such as Germany and Austria.

TRIAL REGISTRATION

Both trials were registered prospectively at the German Clinical Trials Register (Germany: DRKS00029673; Austria: DRKS00029934) in July and August 2022.

Attachment, Feeding Practices, Family Routines and Childhood Obesity: A Systematic Review of the Literature

Childhood obesity is considered a major public health problem. To help prevention and intervention programs targeting families with obese children, this paper is aimed at synthesizing multifactorial and transactional data resulting from studies and reviews assessing relational factors between the child and his or her parents and the child's obesity risk, including the child's and CG's attachment quality, parental feeding practices, and family routines. It is also aimed at assessing the mediation of these links by specific self-regulatory capacities across different developmental periods (0-2, 2-8, and 8-18 years old). The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines were applied in the review methodology. Ten papers were analyzed, including seven empirical studies and three reviews proposing etiological models of childhood obesity. The quality of empirical studies was assessed, and a synthetical model of the results was proposed. This literature review showed that the caregiver's (CG) and the child's attachment quality, along with controlling or permissive feeding practices, and few family routines are mostly mediated by appetite dysregulation and emotional regulation strategies with the development of child obesity. New research topics are proposed to understand other facets of childhood obesity, as well as how to better prevent and treat it.

History of "Serve and Return" and a Synthesis of the Literature on its Impacts on Children's Health and Development

Parent/caregiver sensitivity and responsiveness are important for children's health and development. The "serve and return" metaphor was created to help providers and caregivers understand the importance of sensitive and responsive early caregiving. In this review, we explain the concept of "serve and return", outline historical and theoretical principles that culminated in this metaphor, highlight parent and child constructs associated with "serve and return" interactions, and synthesize literature on sensitive and responsive caregiving and children's health and developmental outcomes. Nurses and other healthcare professionals in public policy, clinical, community, education, and research roles need knowledge of "serve and return" interactions.

Maternal sensitivity in early childhood and body mass index in adolescence: A population-based study on the role of self-regulation as a mediator

Maternal sensitivity has been implicated in various aspects of child health and development, including overweight. However, long-term effects, the role of paternal sensitivity and the explanatory pathways are unclear. This study examined whether maternal sensitivity in early childhood is prospectively associated with adolescent body mass index and whether children's self-regulation mediates this relation. Data from 540 children and their mothers were available from a large cohort study in the Netherlands. Maternal sensitivity was assessed at child ages 1, 3, and at 4 years paternal sensitivity was also included. Children's self-regulation skills were observed at age 3, eating behaviour was assessed at 10 years, and child BMI was measured at 13 years. Longitudinal structural equation modelling was applied. The cross-sectional association between maternal sensitivity and child self-regulation was significant, while lower levels of self-regulation and higher levels of food responsiveness and restrained eating predicted a higher child BMI at 13 years. Furthermore, a direct association of paternal sensitivity at 4 years with BMI at 13 years was found, but only in girls. Maternal sensitivity was not directly associated with child BMI after adjusting for covariates. Our findings showed the importance of self-regulation in the early years for subsequent weight development. Nevertheless, as self-regulation could not explain the relationship between parenting and child weight, research should focus on the contribution of other contextual factors, such as feeding styles and the social environment, to this relationship.

Childhood Obesity: A Potential Key Factor in the Development of Glioblastoma Multiforme

Glioblastoma multiforme (GBM) is a malignant primary tumor type of the central nervous system (CNS). This type of brain tumor is rare and is responsible for 12-15% of all brain tumors. The typical survival rate of GBM is only 12 to 14 months. GBM has a poor and unsatisfactory prognosis despite advances in research and therapeutic interventions via neurosurgery, radiation, and chemotherapy. The molecular heterogeneity, aggressive nature, and occurrence of drug-resistant cancer stem cells in GB restricts the therapeutic efficacy. Interestingly, the CNS tumors in children are the second most usual and persistent type of solid tumor. Since numerous research studies has shown the association between obesity and cancer, childhood obesity is one of the potential reasons behind the development of CNS tumors, including GBM. Obesity in children has almost reached epidemic rates in both developed and developing countries, harming children's physical and mental health. Obese children are more likely to face obesity as adults and develop non-communicable diseases such as diabetes and cardiovascular disease as compared to adults with normal weight. However, the actual origin and cause of obesity are difficult to be pointed out, as it is assumed to be a disorder with numerous causes such as environmental factors, lifestyle, and cultural background. In this narrative review article, we discuss the various molecular and genetic drivers of obesity that can be targeted as potential contributing factors to fight the development of GBM in children.

Overweight and executive functions, psychological and behavioral profile of Spanish adolescents

The prevalence of overweight and obesity among children and adolescents has risen dramatically increasing a major risk factor for non-communicable diseases and cognitive dysfunctions. This study aimed to analyze differences in the executive function´s development between overweight and normal-weight adolescents. As a secondary objective, we aimed to assess differences in adolescents' psychological and behavioral profiles between groups. In order to achieve the study's aim, 105 adolescent students (17.61 ± 7.43 years) completed an online questionnaire that analyzed variables regarding their executive functions' processes, their psychological and physical health as well as lifestyle habits. Results showed that executive functions development is associated with adolescent weight. A higher range of weight presents a lower ability to assess abstract reasoning and to shift cognitive strategies. Nevertheless, no differences were found between groups in the capacity to hold information in mind nor the ability to control impulsive responses. Furthermore, groups showed differences in the number of meals and gastritis, but no significant differences have been found in lifestyle variables such as mobile usage, smoking, physical activity, and hours of sleep per day. The results from the present study could be used to implement multidisciplinary programs to develop healthier habits.

Examining the Relationship between Infant Weight Status and Parent-Infant Interactions within a Food and Nonfood Context

Background: Most observational research examining factors in the home environment that contribute to child adiposity has focused on feeding and physical activity, although aspects of one's nonfood home environment such as parent-child interactions can also impact body weight. The main objectives of this study were to determine if parent-infant interactions under different contexts provide a unique contribution to infants' concurrent adiposity after accounting for known obesity-related covariates. Methods: This was a cross-sectional analysis of 121 9- to 15-month-old infants using data collected at the baseline visit of an ongoing intervention study. Mother-infant interactions during a feeding episode and a free-play task were recorded and coded. Anthropometrics of infants were measured by trained research staff. We used two-step hierarchical multivariable regression models to examine the unique contribution of mother-infant interactions to weight status after accounting for known obesity-related covariates (i.e., maternal age, BMI, education, parity, and gestational age, child sex, breastfeeding duration, age of solid food introduction, and birthweight). Results: Maternal intrusiveness, child negative affect, and child responsiveness during free-play, but not feeding were significantly associated with z-weight-for-length. For every 1-U increase in maternal intrusiveness and child negative affect there was a 0.321 (p = 0.011) and 0.415 (p = 0.028) unit increase in z-weight-for-length, respectively, whereas for every 1-U increase in child responsiveness there was a decrease of 0.386 U in z-weight-for-length (p = 0.025). Conclusion: This research contributes new findings support the idea that parent-child interactions outside of the feeding context may relate to obesity.

Association between Adequate Fruit and Vegetable Intake and CVDs-Associated Risk Factors among the Malaysian Adults: Findings from a Nationally Representative Cross-Sectional Study

This study aimed to investigate the relationship between adequate fruit and vegetable intake, and cardiovascular diseases (CVDs)-associated risk factors (i.e., diabetes, hypertension and hypercholesterolemia) among Malaysian adults without history of chronic diseases. We analyzed the data from 11,172 Malaysian adults (i.e., 5554 male and 5618 female), who participated in the population-based National Health and Morbidity Survey 2015. Multiple logistic regression was employed to determine the relationship between adequate daily intake of fruit and vegetables (i.e., ≥5 servings per day) and undiagnosed diabetes, undiagnosed hypertension, and undiagnosed hypercholesterolemia, after adjustment for sociodemographic characteristics and lifestyle risk factors. The mean age (±SE) of these participants was 40.79 (±0.17) years old. Our data demonstrated an adequate daily intake of fruit and vegetables was inversely associated with undiagnosed hypercholesterolemia (adjusted OR: 0.71; 95% CI: 0.51–0.98). Further analyses demonstrated an inverse association between the adequate daily intake of vegetables alone and undiagnosed hypertension (adjusted OR: 0.71; 95% CI: 0.51–0.98). The findings from this study suggest the need for a holistic public health approach to reinforce public awareness about diet-related diseases, which will eventually aid in the prevention of CVDs among Malaysian adults in the long run.

From zero to thrive: A model of cross-system and cross-sector relational health to promote early childhood development across the child-serving ecosystem

Early relational health between caregivers and children is foundational for child health and well-being. Children and caregivers are also embedded within multiple systems and sectors, or a "child-serving ecosystem", that shapes child development. Although the COVID-19 pandemic has made this embeddedness abundantly clear, systems remain siloed and lack coordination. Fostering relational health amongst layers of this ecosystem may be a way to systematically support young children and families who are facing adversity. We integrate theory, examples, and empirical findings to develop a conceptual model informed by infant mental health and public health frameworks that illustrates how relational health across the child-serving ecosystem may promote child health and well-being at a population level. Our model articulates what relational health looks like across levels of this ecosystem from primary caregiver-child relationships, to secondary relationships between caregivers and child-serving systems, to tertiary relationships among systems that shape child outcomes directly and indirectly. We posit that positive relational health across levels is critical for promoting child health and well-being broadly. We provide examples of evidence-based approaches that address primary, secondary, and tertiary relational health, and suggest ways to promote relational health through cross-sector training and psychoeducation in the science of early development. This model conceptualizes relational health across the child-serving ecosystem and can serve as a template for promoting child health and well-being in the context of adversity.

Examining School and Neighborhood Effects of Socioeconomic Status on Childhood Obesity in the U.S

Obesity amongst Kindergartners in Texas is above the national average, particularly among Hispanic students. Research on the impact of school and neighborhood-level SES on obesity in childhood using multilevel models is lacking. Survey data were collected from Hispanic caregivers of pre-kindergarten students in Fall 2019 (n = 237). Students were clustered in thirty-two neighborhoods and twelve schools. The dependent variable was the child’s body mass index z-score (BMIz). Covariates included the child’s sex, primary caregiver’s marital status, education level, relationship to the child, and family income. Level-two variables included neighborhood poverty and school SES. CTableross-classified multilevel linear regression models were conducted to examine the unique associations of neighborhood poverty and school SES with individual student BMIz, and how they interact. Twenty-four percent of students were classified as overweight, and five percent were classified as obese. The models resulted in a significant association between school SES and BMIz (B = −0.13; SE = 0.06; p < 0.05) and between neighborhood poverty and BMIz (B = −1.41; SE = 0.49; p < 0.01). Individual students’ BMIz decreased as school SES increased and decreased as neighborhood poverty increased. Neighborhood poverty and school SES appear to play a role in the development of obesity in childhood, although in differing directions.

The Mediation Role of Health Behaviors in the Association between Self-Regulation and Weight Status among Preschool Children: A Sex-Specific Analysis

Previous studies have supported the link between children’s self-regulation (CSR) and weight status, but the potential pathways have not been elucidated yet. We aimed to investigate whether and to what extent health behaviors mediate this association, as well as to explore the sex effect. For this study, we recruited 3740 preschoolers in Wuhan, China. The height and weight of children were measured, and a body mass index of the ≥85th percentile was defined as overweight/obesity (OWO). We used the Children’s Behavior Questionnaire, with measured domains including inhibitory control, impulsivity, anger, and attentional focusing, to assess CSR. The primary caregivers’ SR (PSR) was assessed with the Self-Control Scale. Information on lifestyles collected from questionnaires was utilized to construct the health behavior index (HBI). We found that Children’s HBI was associated with both CSR and PSR, inhibitory control (OR = 0.81, p < 0.001), anger (OR = 1.23, p < 0.001), attentional focusing (OR = 0.70, p < 0.001), impulsivity (OR = 1.23, p < 0.001), and PSR (OR = 0.73, p < 0.001). Children’s impulsivity was associated with their OWO (OR = 1.11, p = 0.013) which was partly mediated by the HBI (direct effect: β = 0.092, p = 0.026; indirect effect: β = 0.011, p = 0.007). The sex-specific analysis indicated that this mediation effect was only significant in boys. These results indicated that impulsivity is associated with childhood weight status, which is partially mediated by health behaviors, especially in boys.

Impacts of parental technoference on parent-child relationships and child health and developmental outcomes: a scoping review protocol

BACKGROUND

With increases in the use of technological devices worldwide, parental technoference is a potential threat to the quality of parent-child relationships and children's health and development. Parental technoference refers to disrupted interactions between a parent and child due to a parent's use of a technological device. The aims of this scoping review are to map, describe, and summarize the existing evidence from published research studies on the impacts of parental technoference on parent-child relationships and children's health and development and to identify the limitations in the studies and gaps in the literature.

METHODS

This scoping review will be conducted in accordance with the Joanna Briggs Institute (JBI) methodology. A search for relevant research studies will be undertaken in APA PsycInfo, MEDLINE, Central, Cochrane Database for Systematic Reviews, JBI EBP, and Embase (OVID). CINAHL (Ebsco) and Scopus will also be searched. Grey and popular literature will be excluded. This review will include primary research studies and review papers published in English with no time limit that identify the impacts of technoference on parent-child relationships and child health and developmental outcomes. Parent participants include primary caregivers, either biological, adopted, or foster parents, of children under the age of 18 who engage in technoference. Two reviewers will independently screen the titles, abstracts, and full texts of studies according to the inclusion and exclusion criteria. Disagreements will be resolved through discussion with a third researcher. Data will be extracted into a data charting table including author(s), year of publication, country, research aim, methodology/design, population and sample size, variables/concepts, and corresponding measures and main results. Data will be presented in tables and figures accompanied by a narrative summary.

DISCUSSION

The goal of this scoping review is to present an overview of the evidence on the impacts of parental technoference on parent-child relationships and child and health developmental outcomes, highlighting the current risk of children of today. It will identify gaps in the literature, inform future research, advise recommendations for parents on technological device use, and possibly guide the development of interventions aimed at addressing parental technoference.

The Infant Health Study - Promoting mental health and healthy weight through sensitive parenting to infants with cognitive, emotional, and regulatory vulnerabilities: protocol for a stepped-wedge cluster-randomized trial and a process evaluation within municipality settings

Background

Child mental health problems are a major public health concern associated with poor mental and physical health later in development. The study evaluates a new community-based intervention to promote sensitive parenting and reduce enduring mental health problems and unhealthy weight among vulnerable infants aged 9-24 months.

Methods

We use a step-wedge cluster randomized controlled trial design conducted within a home visiting program offered by community health nurses to infant families in Denmark. Sixteen municipalities are randomly allocated to implement the intervention starting at three successive time points from May 1, 2022 to January 1, 2023. A total of 900-1000 families will be included. A standardized program, Psykisk Udvikling og Funktion (PUF), is used to identify infants with major problems of eating, sleep, emotional or behavioral regulation or developmental problems. The intervention builds on the Video-Feedback Intervention to Promote Positive Parenting (VIPP) program, adapted to the PUF-context and named the VIPP-PUF. Children will be followed up at ages 18 and 24 months. Primary outcome measure is the Strengths and Difficulties Questionnaire (SDQ) at child age 24 months. The other outcome measures include body mass index z-scores, the Ages and Stages Questionnaire Social-Emotional (ASQ:SE2); the Child Behavior Checklist (CBCL 1½ -5); Eating behavior Questionnaires; the Being a Mother-questionnaire (BaM13); the Parental Stress Scale (PSS); and the WHO-5 well-being index (WHO-5). Data on child and family factors are obtained from National registries and the Child Health Database.

Quantitative measures are applied to examine the effectiveness of the VIPP-PUF intervention and the implementation process. Qualitative measures include interviews with CHNs, parents and municipality stakeholders to explore factors that may influence the adherence and effectiveness of the intervention.

Discussion

The study examines a service-setting based intervention building on the promotion of sensitive parenting to vulnerable infants. We use a mixed methods approach to evaluate the intervention, taking into account the influences of COVID-19 pandemic running since March 2020. Overall, the study has potential to add to the knowledge on the possibilities of prevention within the municipality child health care to reduce the risk of mental health problems and unhealthy weight in early childhood.

Play & Grow: prospective observational cohort of toddlers to inform obesity prevention, Columbus, Ohio, USA

PURPOSE

Obesity prevention is increasingly focused on early childhood, but toddlers have not been well-studied, and children born preterm are frequently excluded. The Play & Grow Cohort was established to investigate child growth in relation to parent-child interactions in mealtime and non-mealtime settings.

PARTICIPANTS

Between December 2017 and May 2019, 300 toddlers and primary caregivers were recruited from records of a large paediatric care provider in Columbus, Ohio, USA. This report describes recruitment of the cohort and outlines the data collection protocols for two toddler and two preschool-age visits. The first study visit coincided with enrolment and occurred when children (57% boys) were a mean (SD) calendar age of 18.2 (0.7) months.

FINDINGS TO DATE

Children in the cohort are diverse relative to gestational age at birth (16%, 28-31 completed weeks' gestation; 21%, 32-36 weeks' gestation; 63%, ≥37 weeks' gestation) and race/ethnicity (8%, Hispanic; 35%, non-Hispanic black; 46%, non-Hispanic white). Caregivers enrolled in the cohort are primarily the child's biological mother (93%) and are diverse in age (range 18-54 years), education (23%, high school or less; 20% graduate degree) and annual household income (27%, <US$20 000 24%, ≥US$90 000). Parent-child interactions were video-recorded during play in the laboratory at 18 months (n=299) and during play, reading and mealtime in the home (n=284) at 24 months. The preschool phase of the study was impacted by COVID-19. Parent-child interactions were video-recorded during play and mealtime at home at 36 months (n=141) and during a standardised buffet meal in the laboratory at 42 months (n=50). Caregivers unable to participate in face-to-face visits due to COVID-19 completed questionnaires.

FUTURE PLANS

Assessment during middle childhood is being planned. Future visits will include anthropometric measurements and parent-child interactions at mealtime. School-based outcomes are additionally being considered.

The Impact of Household Chaos and Dietary Intake on Executive Function in Young Children

Children's executive functions (EFs) emerge over time and can be shaped by household environments and dietary intake. However, there is a lack of knowledge about how these factors influence EFs in children aged 18-24 months. This study tested a model exploring the relations between parent-reported dietary intake, household chaos, and child EF. The sample consisted of 294 families participating in the STRONG Kids2 birth cohort study of nutrition and child health. Caregivers completed the Food Frequency Questionnaire (FFQ), the Confusion, Hubbub, and Order Scale (CHAOS), and the Behavior Rating Inventory of Executive Function^®-Preschool Version (BRIEF-P) to assess model variables. Regression analyses revealed a significant and independent association between assorted snacks and processed foods and two EF subscales. There were also significant associations between household chaos and each EF subscale. There was no significant moderation effect. These findings suggest that family households characterized by dysregulation are associated with children's EF difficulties during early childhood and that the role of unhealthy dietary intake in child EF should be explored further. Future longitudinal studies that include multi-method approaches are needed to document the mechanisms through which household chaos impacts child EF over time.

Mediating effect of the parent-child relationship on the association between parenting stress and children's eating behaviors

BACKGROUND

Emerging evidence suggests that parenting stress plays a significant role in children's eating behavior. However, the nature of the relationship between parenting stress and children's health behaviors is still not well understood, possibly because there is limited understanding of the mediating factors. The purpose of this study was to examine the mediating effect of the parent-child relationship on the association between parenting stress and children's eating behaviors in families with young children.

METHODS

Using a cross-sectional study design, we recruited mothers of families with children aged four to six years in the United States. We asked the mothers select one child if she has more than one eligible child. Mothers answered well-validated questionnaires regarding parenting stress, the parent-child relationship, and children's eating behaviors. We utilized a structural equation model to analyze the mediating factors.

RESULTS

A total of 172 mothers of children participated in this study. The children's mean age was 4.92 (SD 0.89) years; 50% of children were female and 71.2% were non-Hispanic Whites. Parenting stress was associated with subcategories of the parent-child relationship (satisfaction with parenting [b* = - 0.69, p < .01], communication [b* = 0.45, p < 0.01], and limit setting [b* = - 0.82, p < .01]). The subcategories of communication and limit setting were negatively associated with food responsiveness in children (b* = - 0.24, p < .01; b* = - 0.46, p < .01, respectively). Limit setting was negatively associated with emotional overeating in children (b* = - 0.49, p < .01). Communication mediated the association between parenting stress and food responsiveness in children (b* = - 0.11, p < .01). The mediating role of limit setting was established in the association between parenting stress and food responsiveness as well as in the association between parenting stress and emotional overeating (b* = 0.38, p < .01; b* = 0.40, p < .01, respectively).

CONCLUSIONS

The parent-child relationship is an important component in improving children's eating behaviors in families that have parents with higher parenting stress levels.

Self-regulatory processes in early childhood as predictors of Hispanic children's BMI z-scores during the elementary school years: Differences by acculturation and gender

Over the last decade, longitudinal research has shown that children's general, top-down self-regulation during early childhood is negatively associated with children's weight status in elementary school. The samples in these previous studies have been primarily White, and no study to date has examined this issue in a sample of Hispanic children from low-income families-a population at high risk for childhood obesity. The present study followed 130 Hispanic children over a time period of three to just under five years, examining the degree to which multiple measures of general, top-down self-regulation, along with a measure of appetite regulation (eating in the absence of hunger), predicted children's BMI z-scores in the early elementary school years. Results showed that children's ability to delay gratification in the preschool years was negatively associated with later BMI z-scores and that children's eating in the absence of hunger was positively associated. In separate models by gender, these relationships were significant only for girls. Moreover, analyses run separately for children of mothers low or high on acculturation showed that the relationship between delay of gratification and later BMI z-scores was significant only for children whose mothers were low on acculturation. Possible socialization and environmental factors contributing to these findings are considered.

A mixed methods analysis of environmental and household chaos: considerations for early-childhood obesity research

BACKGROUND

Chaos has implications for child health that may extend to childhood obesity. Yet, results from studies describing associations between chaos and childhood obesity are mixed. New approaches to studying the environments of young children may help to clarify chaos-obesity relationships.

METHODS

We conducted a concurrent mixed methods analysis of quantitative and qualitative data describing home and neighborhood chaos among a diverse cohort of 283 caregiver-toddlers dyads from Ohio. We examined the underlying structure of environmental and household chaos using exploratory factor analysis then sought to validate the structure using qualitative field notes. We generated total scores for factors of chaos and described their distributions overall and according to cohort characteristics. Additionally, we conducted a thematic content analysis of brief ethnographies to provide preliminary construct validity for our indicators of chaos.

RESULTS

Dyads varied according to household composition, income, education, and race/ethnicity. We found evidence for a multi-factor structure for chaos, which included disorganization and neighborhood noise. Household disorganization scores ranged from 0 to 7.3 and were on average 2.1 (SD = 1.8). Neighborhood noise scores ranged from 0 to 4 and were on average 1.1 (SD = 1.1). Both disorganization and neighborhood noise were associated with indicators of socioeconomic disadvantage, such as lower educational attainment and household income. Qualitative data from households with high and low scores on the two identified factors were aligned in ways that were supportive of construct validity and further contextualized the social and material environments in which chaos occurred.

CONCLUSIONS

Chaos represents a complex construct with implications spanning various disciplines, including childhood obesity research. Previous studies suggest challenges associated with measuring chaos may limit the conclusions that can be drawn about which aspect of chaos (if any) matter most of early childhood weight development. We advance the literature by demonstrating chaos may be comprised of conceptually distinct subdomains. Future childhood obesity prevention research may benefit from more contemporary measure of chaos, such as those relying on direct observations that account for a multifaceted underlying structure.

Relation between Attachment and Obesity in Preschool Years: A Systematic Review of the Literature

Increasing evidence suggests that attachment plays an important role in obesity. However, few studies examined this relationship in preschool children. This study aimed to systematically examine the empirical, peer-reviewed evidence regarding the relationship between attachment quality and obesity in the preschool years. Using established guidelines, relevant peer-reviewed literature published between 2000 and July 2021 was searched through EBSCO. This yielded a total of 1124 records for review. Established inclusion criteria comprised: empirical studies published in peer-review journals; include at least one anthropometric measure and/or food consumption measure. Exclusion criteria comprised: attachment measures not following Bowlby-Ainsworth conceptualization of the construct; children in institutionalized settings; context of severe mental illness, documented substance use disorders, or eating disorders; include only a measure of the psychological aspects of eating; intervention programs. After exclusions, eight studies with a total of 9225 participants met the inclusion criteria. Results support the role of attachment in weight-related outcomes, suggesting that considering attachment in the risk of obesity could contribute to the elaboration of effective prevention and intervention programs. Limitations included the small number of studies, predominately cross-sectional designs, the diversity of methodologies, most samples not including fathers, and lack of evidence about the developmental mechanisms underlying the association between attachment and obesity. More evidence is needed to determine how attachment and obesity are linked, and the potential underlying mechanisms accounting for this relationship.

Does secure base script knowledge mediate associations between observed parental caregiving during childhood and adult romantic relationship quality and health?

Increasingly, attachment representations are being assessed via secure base script knowledge - the degree to which individuals show awareness of the temporal-causal schema that summarizes the basic features of seeking and receiving effective support from caregivers during times of need. Limited research has assessed the links between secure base script knowledge and aspects of adult functioning and the role that secure base script knowledge may play in accounting for associations between early caregiving quality and adulthood functioning. We used follow-up assessments of the NICHD Study of Early Child Care and Youth Development cohort (N = 585) to examine whether secure base script knowledge at age 18 years: (a) is associated with later romantic relationship quality, depressive symptoms, and body mass index (BMI) at age 26 years, and (b) mediates expected associations between the quality of maternal and paternal sensitivity across the first 15 years of life and age-26 outcomes. More access to, and elaborated knowledge of the secure base script predicted less extreme hostility with romantic partners, and better emotional and physical health. Moreover, secure base script knowledge mediated the links between early maternal and paternal sensitivity and both later romantic partner hostility and depressive symptoms, but not BMI.

Childhood Obesity and Maternal Personality Traits: A New Point of View on Obesity Behavioural Aspects

The epidemic spread of childhood obesity in Western society has interested many researchers, who agree in defining it as a multifactorial disease in which not only eating habits and sedentary lifestyle play a role, but also genetic predisposition. The aim of this study was to analyze the personality profile of a group of mothers of children with obesity and to compare this profile to that of a group of mothers of children without obesity. A total of 258 mothers participated in the study (126 mothers of children with obesity and 132 mothers of children without obesity). Weight and height were measured and the body mass index was calculated. The Minnesota Multiphasic Personality Inventory second edition (MMPI-2), evaluating personality and psychological disorders, was used to evaluate the personality profile. The results suggested that mothers of children with obesity score higher than the mothers of children without obesity in all MMPI-2 subscales. In most of these subscales, the differences between the two groups of mothers were statistically significant and with a medium to high effect size. These data suggest a new perspective on childhood obesity, identifying it as a multifactorial pathology that requires a multimodal and multidisciplinary approach that also takes care of caregivers to ensure optimal therapeutic efficacy.

Parent Website Engagement and Health Equity Implications in a Child Care-Based Wellness Intervention

OBJECTIVE

To evaluate demographic differences in parent website engagement in a child care-based wellness intervention.

DESIGN

Parent-reported demographic characteristics and observed website engagement were averaged by child care centers participating in the web-based intervention arm of a cluster randomized controlled trial of wellness interventions.

SETTING AND PARTICIPANTS

Parents of preschoolers in 17 Maryland child care centers.

MAIN OUTCOME MEASURES

Website engagement: (1) webpage views, (2) average time on webpage, and (3) intervention activity completion.

INTERVENTION

Parents received access to a website containing content on wellness-promoting topics (eg, parenting, nutrition, physical activity) and their child care center's activities.

ANALYSIS

Cross-sectional differences in website engagement by demographic characteristics were assessed using ANOVA.

RESULTS

Centers with a high proportion of parents who identified as other than non-Hispanic White and had less than a bachelor's degree had significantly fewer webpage views, and completed significantly fewer intervention activities compared with centers with parents who were predominantly non-Hispanic White and had more than a bachelor's degree.

CONCLUSIONS AND IMPLICATIONS

Demographic differences in parents' child care center website engagement represent disparities that could contribute to health inequities in parents' access to wellness-promoting material. Future efforts could identify factors that eliminate demographic disparities in parent engagement in web-based interventions.

Intergenerational transmission of appetite self-regulation

Parents and other primary caregivers affect the development of children's self-regulation in myriad ways, including via the parent's own self-regulation abilities. Ample evidence supports the association between mother and child self-regulation, yet this has never been experimentally assessed with regard to appetite self-regulation, the self-regulation of food intake. This study sought to explicitly test the associations between mother and child self-regulation across 3 domains: (1) appetite, (2) attentional control, and (3) inhibitory control. A community sample of 88 mother-preschooler dyads (ages 3-5) participated in this cross-sectional, experimental study. Results demonstrated that maternal self-regulation was significantly positively associated with child self-regulation in the appetite domain, b = 0.52, t(63.54) = 2.39, p = .020, but not for attentional or inhibitory control. These results add to the literature on parental influences on self-regulation development in early childhood and suggest that patterns of mother-child associations may vary across domains of self-regulation.

The Role of Social Stress in the Development of Inhibitory Control Deficit: A Systematic Review in Preclinical Models

Inhibitory control deficit and impulsivity and compulsivity behaviours are present in different psychopathological disorders such as addiction, obsessive-compulsive disorders and schizophrenia, among others. Social relationships in humans and animals are governed by social organization rules, which modulate inhibitory control and coping strategies against stress. Social stress is associated with compulsive alcohol and drug use, pointing towards a determining factor in an increased vulnerability to inhibitory control deficit. The goal of the present review is to assess the implication of social stress and dominance on the vulnerability to develop impulsive and/or compulsive spectrum disorders, with the aid of the information provided by animal models. A systematic search strategy was carried out on the PubMed and Web of Science databases, and the most relevant information was structured in the text and tables. A total of 34 studies were recruited in the qualitative synthesis. The results show the role of social stress and dominance in increased drug and alcohol use, aggressive and impulsive behaviour. Moreover, the revised studies support the role of Dopaminergic (DA) activity and the alterations in the dopaminergic D1/D2 receptors as key factors in the development of inhibitory control deficit by social stress.

The impacts of exercise on pediatric obesity

Over the last few decades, the rates of pediatric obesity have more than doubled regardless of sociodemographic categorization, and despite these rates plateauing in recent years there continues to be an increase in the severity of obesity in children and adolescents. This review will discuss the pediatric obesity mediated cardiovascular disease (CVD) risk factors such as attenuated levels of satiety and energy metabolism hormones, insulin resistance, vascular endothelial dysfunction, and arterial stiffness. Additionally, early intervention to combat pediatric obesity is critical as obesity has been suggested to track into adulthood, and these obese children and adolescents are at an increased risk of early mortality. Current suggested strategies to combat pediatric obesity are modifying diet, limiting sedentary behavior, and increasing physical activity. The effects of exercise intervention on metabolic hormones such as leptin and adiponectin, insulin sensitivity/resistance, and body fat in obese children and adolescents will be discussed along with the exercise modality, intensity, and duration. Specifically, this review will focus on the differential effects of aerobic exercise, resistance training, and combined exercise on the cardiovascular risks in pediatric obesity. This review outlines the evidence that exercise intervention is a beneficial therapeutic strategy to reduce the risk factors for CVD and the ideal exercise prescription to combat pediatric obesity should contain both muscle strengthening and aerobic components with an emphasis on fat mass reduction and long-term adherence.

Children, Media and Food. A New Paradigm in Food Advertising, Social Marketing and Happiness Management

The growing number of children who are obese or overweight in certain countries or geographical areas is a fact, as evidenced by the continuous studies and reports on the subject, endorsed or carried out by the World Health Organisation and independent research. In this context, food and beverage advertising can contribute to this. The main objective of this research is to evaluate compliance with the Food and Drink Advertising Code for Children (PAOS Code) in Spain and its relationship with nutritional habits on television, specifically on channels aimed at children. The methodology is therefore mixed: on the one hand, a qualitative technique based on discourse analysis and, on the other, a quantitative technique based on the content analysis of the advertising broadcast for seven consecutive days on three specialised channels and two generalist channels on Spanish television. The results reveal a systematic noncompliance with this code, which translates into inadequate eating habits among children. The immediate conclusion is that 9 out of 10 parts of food and drink advertising do not comply with any of the rules of the PAOS Code and that self-regulation by the advertising companies is negligible and insufficient.

Appetite self-regulation declines across childhood while general self-regulation improves: A narrative review of the origins and development of appetite self-regulation

This narrative review discusses the origins and development of appetite self-regulation (ASR) in childhood (from infancy to age 6 or 7 years). The origins, or foundations, are the biological infrastructure associated with appetite regulation and appetite self-regulation. Homeostatic regulation in infancy is examined and then evidence about developmental change in components of ASR. The main ASR-related components covered are: delay-of-gratification, caloric compensation, eating in the absence of hunger, food responsiveness/hedonics and fussy eating. The research included behavioral measures, parent-reports of appetitive traits and fMRI studies. There were two main trends in the evidence: a decline across childhood in the components of ASR associated with food approach (and therefore an increase in disinhibited eating), and wide individual differences. The decline in ASR contrasts with general self-regulation (GSR) where the evidence is of an improvement across childhood. For many children, bottom-up automatic reactive processes via food reward/hedonics or food avoidance as in fussy eating, appear not to be matched by improvements in top-down regulatory capacities. The prominence of bottom-up processes in ASR could be the main factor in possible differences in developmental paths for GSR and ASR. GSR research is situated in developmental science with its focus on developmental processes, theory and methodology. In contrast, the development of ASR at present does not have a strong developmental tradition to access and there is no unifying model of ASR and its development. We concluded (1) outside of mean-level or normative changes in the components of ASR, individual differences are prominent, and (2) there is a need to formulate models of developmental change in ASR together with appropriate measurement, research designs and data analysis strategies.

Neural Mechanisms of Food Decision-Making in Children

PURPOSE OF REVIEW

The goal of the current paper is to review the literature on the neural and behavioral factors involved in food decision-making in youth.

RECENT FINDINGS

Recent neuroimaging studies that employ passive viewing paradigms have found that exposure to food-related cues activate reward, motor planning, and attentional salience signals in children. Greater activations of reward signals and/or lower activations of control signals are associated with overeating and weight gain. Neuroimaging studies with decision-making paradigms have found the reward network in the brain activates during food choices, while control network activates less strongly. Findings suggest that exposure to food cues activates reward/valuation network, but activation of control network tends to be relatively weaker in children. Hedonic aspects of foods are predominantly considered in children's food choices, and their dietary self-control is not matured yet. The increased activation in reward network and the decreased activation in control network are associated with risk of developing obesity.

Parenting and Child Development: A Relational Health Perspective

A child's development is embedded within a complex system of relationships. Among the many relationships that influence children's growth and development, perhaps the most influential is the one that exists between parent and child. Recognition of the critical importance of early parent-child relationship quality for children's socioemotional, cognitive, neurobiological, and health outcomes has contributed to a shift in efforts to identify relational determinants of child outcomes. Recent efforts to extend models of relational health to the field of child development highlight the role that parent, child, and contextual factors play in supporting the development and maintenance of healthy parent-child relationships. This review presents a parent-child relational health perspective on development, with an emphasis on socioemotional outcomes in early childhood, along with brief attention to obesity and eating behavior as a relationally informed health outcome. Also emphasized here is the parent-health care provider relationship as a context for supporting healthy outcomes within families as well as screening and intervention efforts to support optimal relational health within families, with the goal of improving mental and physical health within our communities.

Affectionless control: A parenting style associated with obesity and binge eating disorder in adulthood

OBJECTIVE

Obesity is rising globally with a heavy health and economic burden. Early attachment experiences are relevant to the development of obesity. The purpose of this study was to investigate if parental care and attachment style experienced in childhood is associated with obesity, with or without binge eating disorder (BED), in adulthood.

METHOD

Parental style, personality traits, and psychopathology were assessed in 810 clinically referred adults with obesity, of whom 357 with BED and 453 without BED (non-BED), and 463 healthy subjects (HS). Assessments included the Parental Bonding Instrument, Temperament and Character Inventory, Eating Disorder Inventory-2, Symptom Checklist-90 and Beck Depression Inventory-II.

RESULTS

Both BED and non-BED reported lower maternal and paternal care and higher overprotection than HS. BED reported worse levels of parental care than non-BED and HS. 'Affectionless control' parenting style was more frequently reported by both BED and non-BED than HS. No significant differences in parenting style emerged between BED and non-BED.

CONCLUSIONS

Perception of parental 'affectionless control' was associated with obesity in adults, and lower quality of parental care was more frequently reported by participants with BED. Parental style may constitute an important target for early interventions to prevent obesity.

Longitudinal Associations Among Diet Quality, Physical Activity and Sleep Onset Consistency With Body Mass Index z-Score Among Toddlers in Low-income Families

BACKGROUND

Habits surrounding health behaviors (i.e., sleep, physical activity, diet) are developed in toddlerhood. Lack of consistent health habits may increase obesity risk among toddlers in low-income families.

PURPOSE

To compare the role of sleep onset consistency, physical activity and diet quality as mediators between household poverty and toddler weight.

METHODS

Two hundred and seven toddlers (mean age = 20.2 months, 46% female, 68.1% Black) participating in an obesity prevention trial were assessed at three time points over 12 months. Using Actical accelerometers, we assessed sleep and physical activity at each time point for up to 1 week. We defined sleep onset consistency as the standard deviation of sleep onset across all days. We calculated the Healthy Eating Index-2015 from a 24-hr dietary recall. We used WHO standards to calculate BMI-for-age z-scores from toddlers' weight/length, and calculated poverty ratio from parent-reported income and family size. Multilevel mediation models tested toddler sleep onset consistency, physical activity, and diet quality as mediators between household poverty and toddler BMI z-score.

RESULTS

Toddlers from households with higher poverty ratios had more inconsistent sleep onset times. Toddlers with more inconsistent sleep onset times had higher BMI z-scores across all timepoints, even when accounting for physical activity and diet quality. Sleep onset consistency indirectly explained the association between household poverty and BMI z-score.

CONCLUSIONS

Inconsistent sleep schedules could help explain the association between poverty and BMI. Future research should examine strategies to support low-income families to develop and maintain routines as a mechanism to prevent obesity and reduce disparities.

Childhood Adversity and Affective Touch Perception: A Comparison of United Kingdom Care Leavers and Non-care Leavers

In the United Kingdom, the most common reasons for a child to come under the care of social services are neglect and abuse. Such early childhood adversity is a risk factor for social-isolation and poor mental health in adulthood. Touch is a key channel for nurturing interactions, and previous studies have shown links between early somatosensory input, experience dependent neural plasticity, and later life emotional functioning. The aim of the present study was to test the relationship between childhood neglect/abuse and later life experiences, attitudes, and hedonic ratings of affective touch. Here, affective touch is defined as low force, dynamic touch which C-Tactile afferents (CTs) respond optimally to. We hypothesized that a childhood lacking in early nurturing tactile stimulation would be associated with reduced sensitivity to socially relevant affective touch in adulthood. To test this, 19 care leavers (average 9.32 ± 3.70 years in foster care) and 32 non-care leavers were recruited through opportunity sampling (mean age = 21.25 ± 1.74 years). Participants completed a range of psychophysical somatosensory tests. First, they rated the pleasantness of CT-optimal (3 cm/s) and non-CT-optimal (0.3 and 30 cm/s) stroking touch applied to their forearm, both robotically and by an experimenter. They also made vicarious ratings of the anticipated pleasantness of social tactile interactions depicted in a series of videos. Finally, they filled in the Childhood Trauma Questionnaire (CTQ) and the Touch Experiences and Attitudes Questionnaire (TEAQ). As expected, care leavers reported significantly higher levels of childhood trauma than the control group. They also reported significantly lower levels of positive childhood touch compared to non-care leavers, but their attitudes and experiences of current intimate and affiliative touch did not differ. Across all psychophysical tests, care leavers showed specific reduction in sensitivity to the affective value of CT targeted 3 cm/s touch. The results of this study support the hypothesis that a lack of nurturing touch in early developmental periods leads to blunted sensitivity to the specific social value of affective touch. Future research should investigate the neural and physiological mechanisms underlying the observed effect.

Raising Well at Home: a pre-post feasibility study of a lifestyle intervention for caregivers and their child with obesity

Background

Few efficacious pediatric obesity interventions have been successfully translated and sustained in real-world practice, often due to inadequate fit with the priorities of under-resourced populations. Lifestyle interventions, which incorporate tailoring of essential weight loss ingredients and adaptation of mode and intensity to the living circumstances of children with obesity, are needed. The purpose of this pilot study was to test the feasibility and efficacy of a tailored lifestyle intervention for caregivers and their children with obesity, conducted in partnership with Envolve, Inc., a family of comprehensive health solutions and wholly owned subsidiary of Centene Corporation.

Methods

This 6-month pilot study employed a pretest-posttest design to assess the impact of a tailored lifestyle intervention delivered by peer coaches on (a) caregiver and child weight impacted by changes in dietary intake, walking, and screen time; (b) changes in the home environment; and (c) caregiver engagement and satisfaction. The intervention was delivered via 3 core home visits every 4-6 weeks, with additional support via text.

Results

The majority of caregivers were female (95.2%) and Black (73.7%). Children had median age of 11.1 years and majority were female (57.6%), with a median BMI near the 99th percentile (Mdn 98.8, IQR 3.5) or 118.3% (IQR 35.8) of the 95th percentile for their sex and age. Participants expressed high satisfaction with the program (mean range 96.7-100.0% agreement on satisfaction items). From baseline to post, caregivers' BMI decreased by 1.8% (p = 0.016, r = 0.22), while children's BMI percentile z-score decreased significantly (p = 0.023, r = 0.18) and BMI percent of the 95th percentile remained constant (p = 0.05, r = 0.15). Caregivers and children decreased sugar-sweetened beverage intake (p = 0.026, r = 0.22; p = 0.006, r = 0.23, respectively), reduced presence of soda in the home (p = 0.002, g = 0.43), and decreased screen time (p = 0.046, g = 0.22). Other eating and walking behaviors remained stable for caregivers and child.

Conclusion

The Raising Well at Home pilot demonstrated that tailored lifestyle interventions, delivered by peer coaches in the home and via text, are feasible and can improve weight, eating, and environmental measures of caregivers and children with obesity. Future work should determine the effectiveness, sustainability, and scalability of this intervention in sites located across the country.

Results of the 3 Pillars Study (3PS), a relationship-based programme targeting parent-child interactions, healthy lifestyle behaviours, and the home environment in parents of preschool-aged children: A pilot randomised controlled trial

BACKGROUND

Early childhood is a critical period for the development of obesity, with new approaches to prevent obesity in this age group needed. We designed and piloted the 3 Pillars Study (3PS), a healthy lifestyle programme informed by attachment theory for parents of preschool-aged children.

METHODS

A 2-arm, randomised controlled pilot study was conducted to assess the effectiveness of 3PS, a 6-week programme involving a half-day workshop plus 6-week access to a study website. The programme was designed to promote routines around healthy lifestyle behaviours, including sleep, limited screen use, and family meals, within the context of positive, reciprocal parent-child interactions. Parents (n = 54) of children aged 2-4 years who regularly exceeded screen use recommendations (≥1 hour per day), were randomised to the 3PS programme (n = 27) or a wait-list control group (n = 27). Child screen time at 6 weeks was the primary endpoint. Frequency of family meals, parent feeding practices, diet quality, sleep, Child Routine Inventory (to assess predictability of commonly occurring routines), and household chaos were also assessed. Study data were collected online at baseline, 6 weeks, and 12 weeks via REDCap.

RESULTS

No group differences were observed for changes from baseline in screen time (primary endpoint), feeding behaviour scores, Child Routine Inventory scores, or total night time sleep duration at 6 and 12 weeks, although all measures improved in the hypothesised direction in the 3PS group. Compared with controls, the intervention group demonstrated significant improvements from baseline in household chaos scores (i.e. a reduction in chaos) and a number of measures of sleep outcomes, indicating improved sleep continuity. The programme was highly acceptable to parents.

CONCLUSIONS AND RECOMMENDATIONS

A relational approach appears promising as a novel way to promote healthy lifestyle behaviours associated with the prevention of childhood obesity in children aged 2-4 years. A larger study is warranted.
