A substantial body of literature links attachment to childhood obesity. However, research on the mechanisms underlying this association is scarce. The present study aimed to test four serial indirect path models to examine whether caregivers' insecure attachment is related to children's food consumption, through its influence on emotional and feeding responsiveness.

The effects of emotion on memory are wide-ranging and powerful, but they are not uniform. Although there is agreement that emotion enhances memory for individual items, how it influences memory for the associated contextual details (relational memory, RM) remains debated. The prevalent view suggests that emotion impairs RM, but there is also evidence that emotion enhances RM.

The widespread discrimination against individuals with obesity often stems from a simplistic perception of obesity as a mere consequence of personal choices of overeating and insufficient physical activity. This reductionist perception fails to acknowledge the complexity of the epidemic of obesity, which extends beyond diet and exercise decisions. The concept of appetite self-regulation (ASR) has been explored as a crucial element in identifying obesogenic behavioral approaches to food.

Objective: This study aimed to investigate the mediating effects of caregiver responses to a child's negative emotions on the associations between infant temperament and emotional overeating in preschool children.

Method: A sample of 358 children and their caregivers enrolled in the STRONG Kids 2 (SK2) birth cohort study ( = 468) provided data for this analysis. Caregivers completed questionnaires assessing child temperament at 3 months, caregiver response to negative emotions at 18 months, and child emotional overeating at 36 months.

Background: The quality of parent-child relationships has been examined as a contributor to children's healthy behaviours and weight outcomes, but the mechanisms accounting for associations remain understudied.

Objective: This study examined whether the quality of early parent-child relationship is associated with adolescent obesity risk and whether self-regulation and (un)healthful food consumption mediate these associations.

Methods: Employing structural equation modelling, two theory-driven models were examined using a large sample (N = 1237) drawn from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development.

Objective: To test the hypothesis that healthy weight status and adherence to American Academy of Pediatrics (AAP) guidelines for diet and physical activity would extend to greater executive function (EF) at age 24 months.

Study Design: Parents of 24-month-old children from the STRONG Kids 2 cohort study (n = 352) completed the Behavioral Rating Inventory of Executive Function for Preschoolers (BRIEF-P) and reported physical activities, diet, and screen time. Toddlers met AAP guidelines if they consumed at least 5 servings of fruits and vegetables, were physically active, refrained from sugar-sweetened beverages, and limited daily screen time to <60 minutes.

Eating behaviors are shaped at an early age, persist into adulthood, and are implicated in the development of physical health outcomes, including obesity. Faster bite speed has been identified as an obesogenic eating behavior, prompting researchers to examine child and family factors associated with children's variability in bite speed. Child temperament, involving phenotypes of reactivity and regulation, and distractions in family food contexts are fruitful areas of investigation, but few studies have examined the interplay among these factors and their associations with bite speed.

Emotional eating has been linked to child temperament and family environment factors, such as household chaos. However, few studies have examined how child and home characteristics independently and together influence children's overeating and undereating in response to negative emotions. The current study examined associations among child temperament, household chaos, and emotional eating in children 18-24 months of age, and interaction effects were also tested.

Objective: Childhood obesity is considered one of the most important public health problems around the world. Chile is currently one of the Latin American countries with a high prevalence of childhood obesity. Given that parents' food parenting practices shape their children's lifelong eating habits, addressing those practices is key to curbing later problems of obesity.

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 role of early child care experiences on the development of the mother-child attachment relationship has been studied extensively. However, no prospective studies of early child care have addressed how these experiences might be reflected in the content of attachment representations during adolescence and beyond. The goal of this study was to estimate relatively precise associations between child care quality, child care quantity, and type of care in the first 54 months of life and the content of adolescents' attachment representations around age 18 years ( = 857; 51% female; 78% White, non-Hispanic; income-to-needs ratio = 4.

Although there is a large body of research connecting emotion to eating behaviors, little is known about the role of caregivers' responses to children's emotions in the context of child feeding. The purpose of this study was to analyze the relation between caregivers' emotional responsiveness and feeding responsiveness. The mothers of 137 children between 2 and 6 years of age reported on their responses to children's negative emotions using the Coping with Children's Negative Emotions Scale and on their feeding practices using the Comprehensive Feeding Practices Questionnaire.

Background: Picky eating (PE) behavior is common in early childhood, but persistent PE is associated with unhealthy development and caregiver-child stress during feeding. Identifying modifiable feeding and parent-child relationship factors that impact PE is important for decreasing risks associated with PE.

Objective: This study examined associations between caregiver Feeding Responsiveness (FR) and child PE behaviors using caregiver reports and observations of family mealtimes.

Increasingly, attachment representations are being assessed via - 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 ( = 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.

Emotional well-being depends on the ability to adaptively cope with various emotional challenges. Most studies have investigated the neural mechanisms of emotion regulation strategies deployed relatively later in the timing of processing that leads to full emotional experiences. However, less is known about strategies that are engaged in earlier stages of emotion processing, such as those involving attentional deployment.

Research indicates that youths with overweight and obesity often face difficulties in peer relationships. The current research examined longitudinal associations between youths' peer competence (, successful interactions with peers), friendship quality (, disclosure, conflict resolution, and companionship with a best friend), and body mass index (BMI) z-score when they were 3 to 15 years of age. A subsample of 1292 majority White families from the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth Development (SECCYD) were included in the analyses.

Responsive feeding and frequency of family mealtimes are related to healthier eating behaviors and weight outcomes in children and adolescents. Distractions at mealtimes are related to greater intake of unhealthy food and a less positive mealtime emotional climate. However, there is little understanding of the effects of routines and father availability on distractions at family meals, and there is limited research investigating the effects of distractions among all family members on maternal feeding practices in toddlerhood.

Introduction: The Comprehensive Feeding Practices Questionnaire (CFPQ) assesses 12 specific parent feeding practices (Musher-Eizenman & Holub, 2007). However, the original 12-factor structure may not be consistent across age groups, and no studies have yet evaluated the factor structure of the CFPQ over time. Therefore, the aim of the current study is to evaluate the model fit of the original and alternative CFPQ factor structures at two time points in early childhood.

Objective: Mealtime emotional climate (MEC) is related to parent feeding and mental health, and possibly to child food consumption. However, MEC has been inconsistently assessed with a variety of coding schemes and self-report instruments, and has not been examined longitudinally. This study aims to characterize MEC systematically using an observational, count-based coding scheme; identify whether parent feeding or mental health predict MEC; and examine whether MEC predicts child food consumption and weight.
