Early mother-child dyadic pathways to childhood obesity risk: A conceptual model

Early Life Surgency, but not Effortful Control or Negative Affectivity, Is a Mediating Variable Between Maternal Pre-Pregnancy Body Mass Index and Childhood Obesity Risk

Maternal gestational obesity is related to risk of obesity in the child. This risk may be in part mediated by altered child temperament, which can affect mother-child interactions, including feeding and soothing behaviors that affect obesity risk. Our objective was to examine the association between maternal pre-pregnancy BMI and child zBMI and determine if child temperament, specifically positive Affectivity/Surgency, mediates this association. Using conditional process modeling, we analyzed data from 408 mother-child dyads enrolled in the Alberta Pregnancy Outcomes and Nutrition (APrON) study. Child temperament was assessed at 3 years of age via a parent report measure, the Child Behavior Questionnaire (CBQ), and child zBMI was calculated from in-person measurements of child height and weight at 4-5 years of age. Bivariate correlations showed that there was a significant positive correlation between zBMI and Surgency (r = 0.11, p = 0.03), and zBMI was also correlated with maternal pre-pregnancy BMI (r = 0.12, p = 0.02). Multivariable regression revealed that maternal pre-pregnancy BMI (adjusted β = 0.15, 95% confidence interval [CI]; 0.00-0.05, p = 0.02) and Surgency scores (adjusted β = 0.14, 95% CI; 0.02-0.28, p = 0.03) were associated with higher child zBMI at 4-5 years of age. Mediation analysis showed that Surgency mediated the association between pre-pregnancy BMI and child zBMI. Our models controlled for maternal gestational weight gain, gestational diabetes, socioeconomic status, maternal anxiety and depression, and gestational age at birth. Overall, maternal pre-pregnancy BMI was positively associated with child zBMI, and this association was mediated by higher child Surgency scores.

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.

Household chaos, child temperament, and structure-related feeding practices in toddlerhood: A moderation analysis

Structure-related feeding practices may promote intuitive child eating behaviors and foster responsiveness to internal cues of hunger and satiety. Caregivers' ability to engage in structure-related feeding practices likely depends on a complex ecology of factors, including household- and child-characteristics. This study examined associations between household chaos and structure-related feeding practices, and the moderating effect of child temperament. Data were from 275 caregiver-toddler dyads from central Ohio. Child temperament was reported by caregivers when children were 18 months of age, whereas household chaos and structure-related feeding practices were reported by caregivers when children were 36 months of age. Multivariable linear regression models were constructed to assess the relationship between chaos and structure-related feeding practices. Interaction terms between household chaos and three dimensions of child temperament were tested to determine whether temperament moderated the relationship between chaos and structure-related feeding practices. Household chaos was not independently associated with structure-related feeding practices, but higher levels of child effortful control were associated with greater mealtime structure. There was a statistically significant interaction between household chaos and child temperamental surgency, such that greater levels of chaos were associated with less structured mealtimes, but only when children had low-surgency. Findings suggest household chaos and child temperament inform caregiver feeding practices, but the influence of chaos may depend on more proximal factors, like child temperament. Recommendations to improve caregiver-child feeding interactions should be sensitive to characteristics of the broader family home environment.

Prenatal maternal cortisol, stress and anxiety, and childhood obesity at 5 years: a nested case-control study

BACKGROUND

Paediatric obesity is a global public health issue. Prenatal maternal mental health is potentially implicated in the development of childhood obesity. This study examined associations between prenatal maternal cortisol, self-reported stress, anxiety and depression in the second trimester, and childhood overweight and obesity at 5 years of age.

METHODS

A nested case-control study was conducted using data from the Irish prospective longitudinal birth cohort SCOPE BASELINE. Cases were children with overweight or obesity, operationalised as having a BMI z-score above +2 standard deviations. Controls were children with a BMI z-score between -0.5 and 0.5 standard deviations at 5 years of age. Two to one matching by sex was conducted. Thirty-eight cases and 83 sex-matched controls were included. Maternal serum cortisol concentration and self-reported stress, anxiety and depression were measured at 15 ± 1 and 20 ± 1 weeks gestation. Conditional logistic regression analyses were conducted to examine associations between prenatal maternal cortisol and self-reported stress, anxiety and depression, and childhood overweight and obesity.

RESULTS

Despite some evidence for associations between anxiety and depression, and child BMI z-scores in univariate analyses, adjusted models indicated no associations between prenatal maternal stress (OR: 1.02, 95% CI: 0.94-1.12), anxiety (OR: 1.03, 95% CI: 0.97-1.09), depression (OR: 1.04, 95% CI: 0.91-1.19), or cortisol concentration (OR: 0.99, 95% CI: 0.99-1.00) and child BMI z-score.

CONCLUSION

Our findings do not provide support for associations between foetal exposure during the second trimester of pregnancy and maternal cortisol, stress and anxiety, and childhood overweight or obesity at 5 years of age.

Child and Maternal Factors Associated with Feeding Practices in Children with Poor Growth

The development of adequate growth and healthy eating behaviors depends on nutritious food and responsive feeding practices. Our study examined (1) the relationship between maternal concern about child weight or perceived feeding difficulties and their feeding practices, and (2) the moderating role of child temperament and maternal mental health on their feeding practices. A cross-sessional study included mother-child dyads (n = 98) from a tertiary growth and feeding clinic. Children had a mean age of 12.7 ± 5.0 months and a mean weight-for-age z-score of -2.0 ± 1.3. Responsive and controlling feeding practices were measured with the Infant Feeding Styles Questionnaire. Spearman correlation and moderation analysis were performed. Maternal concern about child weight and perceived feeding difficulties were negatively correlated with responsive feeding (r = -0.40, -0.48, p < 0.001). A greater concern about child weight or perceived feeding difficulties was associated with greater use of pressure feeding practices when effortful control was low (B = 0.49, t = 2.47, p = 0.01; B = -0.27, p = 0.008). Maternal anxiety had a significant moderation effect on the relationship between feeding difficulty and pressure feeding (B = -0.04, p = 0.009). Higher maternal concern about child weight and perceived feeding difficulties were associated with less responsive satiety feeding beliefs and behaviors. Both child effortful control and maternal anxiety influenced the relationship between weight and feeding concerns and the use of pressure feeding practices.

Health-related behaviors and weight-related outcomes within sibling pairs: A systematic review

BACKGROUND

Siblings reciprocally contribute to mutual social and physical development. The aim of this review was to examine the health-related behaviors and weight-related outcomes within child-sibling pairs and to determine how these factors vary by sibling composition.

METHODS

Following the PRISMA guidelines, a systematic review of studies published since 2000 obtained from MEDLINE, CINAHL, PubMed, Cochrane Reviews, Web of Science, PsycINFO, Health and Wellness, and Science Direct was performed. The eligibility criteria for inclusion were: 1) peer-reviewed and published in English; 2) included children ages 2 to 20 and their siblings; and 3) explored health-related behaviors (i.e., diet) and/or weight-related outcomes (i.e., body weight) within child-sibling dyads.

RESULTS

A total of 13 studies were included in the review. The study findings are summarized according to three major themes: 1) sibling concordance in health-related behaviors and weight-related outcomes, 2) differences in health-related behaviors within weight-concordant/weight-discordant sibling dyads, and 3) influence of sibling composition on health-related behaviors and weight-related outcomes.

CONCLUSIONS

Family-based interventions for childhood obesity may benefit from including siblings as key family members in promoting children's health-related behaviors and preventing excessive weight gain. Future studies should explore variable sibling dynamics (e.g., adoptive siblings) in more culturally/racially diverse families to further explore the role of a sibling in a child's health.

IMPLICATIONS TO PRACTICE

The findings of this study may help healthcare providers in developing effective family-based obesity interventions for families with more than one child in their household.

Malnutrition in mother-child dyads in the Brazilian National Survey on Child Nutrition (ENANI-2019)

Malnutrition affects billions of individuals worldwide and represents a global health challenge. This study aimed to determine the prevalence of malnutrition (undernutrition or overweight) among mother-child dyads in children under 5 years old in Brazil in 2019 and to estimate changes in this prevalence from 2006 to 2019. Individual-level data from the Brazilian National Survey on Child Nutrition (ENANI-2019) and the Brazilian National Survey of Demography and Health of Women and Children carried out in 2006 (PNDS 2006) were analyzed. Malnutrition outcomes in mother-child dyads included overweight mother and child, undernourished mother and child, and the double burden of malnutrition, i.e., overweight mother and child having any form of undernourishment (stunting, wasting, or underweight). Prevalence and 95% confidence intervals (95%CI) were estimated. Most women (58.2%) and 9.7% of the children were overweight, 6.9% were stunted, and 3.1% of mothers and 2.9% of the children were underweight. The prevalence of overweight in the mother-child dyad was 7.8% and was statistically higher in Southern Brazil (9.7%; 95%CI: 7.5; 11.9) than in the Central-West (5.4%; 95%CI: 4.3; 6.6). The prevalence of overweight mother and stunted child was 3.5%, with statistically significant difference between the extremes of the mother's education [0-7 vs. ≥ 12 years, 4.8% (95%CI: 3.2; 6.5) and 2.1%, (95%CI: 1.2; 3.0), respectively]. Overweight in the dyad increased from 5.2% to 7.8%, and the double burden of malnutrition increased from 2.7% to 5.2% since 2006. Malnutrition in Brazilian mother-child dyads seems to be a growing problem, and dyads with lower formal education, higher maternal age, and from the South Region of Brazil were more vulnerable.

A prospective study on body image disturbances during pregnancy and postpartum: the role of cognitive reappraisal

Background

During pregnancy, body size rapidly modifies over a relatively short period. Literature emphasizes the need to identify the factors that influence body image during peripartum as the extent of women's adaptation to these changes has significant repercussions on both mother's and newborn's health. Emotion regulation strategies (i.e., expressive suppression and cognitive reappraisal) were linked to body image in the general and clinical population, but no studies were conducted in the peripartum. The present study aims to investigate the longitudinal impact of prepartum body image disturbances on postpartum body image disturbances and to evaluate the mediational role of emotional regulation strategies.

Methods

A total of 133 pregnant women completed a three-phase longitudinal study. Women answered online questionnaires during the second (T1) and the third (T2) trimesters of pregnancy, and at about 6 months postpartum (T3).

Results

Findings indicated that body image disturbances at T1 were a significant predictor of body image disturbances in the postpartum (1 year after the first assessment). Moreover, cognitive reappraisal measured at T2 partially mediated this relationship: body image disturbances in the second trimester of pregnancy were linked to less use of cognitive reappraisal in the third trimester of pregnancy, and this, in turn, was associated with worse body image disturbances at 6 months after birth.

Conclusion

Findings of this longitudinal study highlight the importance of assessing body image disturbances during pregnancy to early identify women at risk, and suggest cognitive reappraisal as a possible target intervention.

The Interdependent Nature of Mother's and Children's Temperament and Eating Behaviors on Weight

OBJECTIVES

The family environment is an important contextual factor for parent and child weight within families. Using an Actor-Partner Interdependence Model, the current study examined (1) the effect of child and mother temperament (i.e., negative affectivity, effortful control, and impulsivity) on mother and child weight, (2) the effect of mother eating behaviors on mother and child weight, and (3) how temperament might moderate the relationships between mother eating behaviors and mother and child weight.

METHODS

The sample consisted of 220 mother-child dyads with children between 4 and 6 years of age (66.8% classified as low-, 25.9% middle-, and 5.5% high-income). Mothers completed questionnaires on their own temperament and eating behaviors as well as child temperament. Weight measures were assessed in the laboratory for both mother and child.

RESULTS

Mother's negative affectivity and impulsivity were negatively related to mother's weight while children's impulsivity was positively related to children's and mother's weight. Mother's eating behaviors were also positively related to mother's weight. The interaction between child impulsivity and mother eating behaviors was significant; the association of mother eating behaviors with mother weight depended on child impulsivity. Specifically, when children had higher impulsivity, mothers had the highest weight. When children had average or lower impulsivity, mother weight was higher with higher endorsement of unhealthy eating behaviors.

CONCLUSIONS

Findings suggest that after adjusting for the interdependent nature of temperament traits and weight, child impulsivity is an important factor associated with current weight for both mothers and children. Results also provide important implications for the impact children can have on their mothers.

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.

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.

Results from the Strong Families Start at Home/Familias Fuertes Comienzan en Casa: feasibility randomised control trial to improve the diet quality of low-income, predominantly Hispanic/Latinx children

OBJECTIVE

To describe the feasibility, acceptability and results of Strong Families Start at Home, a 6-month pilot trial of a home-based food parenting/nutrition intervention.

DESIGN

Pilot randomised controlled trial.

SETTING

Participants received six visits with a community health worker trained in motivational interviewing (three home visits, three phone calls); an in-home cooking or reading activity; personalised feedback on a recorded family meal or reading activity; text messages and tailored printed materials.

PARTICIPANTS

Parents and their 2-5-year-old child were randomised into intervention (responsive food parenting practices/nutrition) or control (reading readiness) groups.

RESULTS

Parents (n 63) were mostly mothers (90 %), Hispanic/Latinx (87 %), born outside the USA (62 %), with household incomes <$25 k (54 %). Despite delivery during COVID-19, 63 % of dyads were retained at 6 months. The intervention was delivered with high fidelity. All parents in the intervention group (n 24) expressed high levels of satisfaction with the intervention, which produced positive treatment effects for whole and total fruit component Healthy Eating Index-2015 scores (point estimate (PE) = 2·14, 95 % CI (0·17, 1·48); PE = 1·71, 95 % CI (0·16, 1·47), respectively) and negative treatment effects for sodium (PE = -2·09, 95 % CI (-1·35, -0·04)). Positive treatment effects also resulted for the following food parenting practices: regular timing of meals and snacks (PE = 1·08, 95 % CI (0·61, 2·00)), reducing distractions during mealtimes (PE = -0·79, 95 % CI (-1·52, -0·19)), using food as a reward (PE = -0·54, 95 % CI (-1·35, -0·04)) and providing a supportive meal environment (PE = 0·73, 95 % CI (0·18, 1·51)).

CONCLUSION

Given the continued disparities in diet quality among low-income and diverse families, continued efforts to improve child diet quality in fully powered intervention trials are needed.

Early maternal sensitivity and markers of physical health: Enduring or transient associations from childhood to adulthood?

Individual differences in the quality of early experiences with primary caregivers have been reliably implicated in the development of socioemotional adjustment and, more recently, physical health. However, few studies have examined the development of such associations with physical health into the adult years. To that end, the current study used prospective, longitudinal data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (N = 1,306, 52% male, 77% White/non-Hispanic) to investigate whether associations between direct observations of maternal sensitivity in the first 3 years of life and repeated assessments of two commonly used, objective indicators of physical health (i.e., body mass and mean arterial blood pressure) remained stable or diminished in magnitude over time. Associations between early maternal sensitivity and lower body mass remained relatively stable from age 54 months to 26 years and were robust to the modeling of autoregressive and second-order stability processes as well as the inclusion of potential demographic confounders. In contrast, although associations between early caregiving and lower mean arterial pressure remained relatively stable from Grade 4 to age 15 years (the oldest age for which mean arterial pressure was assessed thus far), these associations were not robust to the inclusion of covariates and the modeling of second-order stability processes.

Parent-reported barriers to establishing a healthy diet with young children in Australia

BACKGROUND

Parents' beliefs and behaviours affect children's nutrition, eating behaviours, and health outcomes; however, little is known about parents' experiences and perspectives on establishing a healthy diet with young children.

METHODS

A community-recruited sample of 391 parents of young children (under age 5) completed an anonymous cross-sectional online survey assessing the degree to which their children met recommendations outlined in Australian nutrition guidelines, perceived barriers to establishing a healthy diet with their child, and interest in receiving tips/information about establishing healthy eating habits with their children. Descriptive statistics illustrated proportions of children adhering to recommendations. Thematic analysis was used to analyse qualitative data.

RESULTS

Adherence to recommended nutrition guidelines varied across age groups. Most children across all age groups had water as their main drink, routinely consumed a variety of fruit, and consumed sweet drinks or fast foods only rarely. In contrast, less than half of 2- and 3-year-olds regularly consumed a variety of vegetables. The proportion of children consuming discretionary "treat" foods increased sharply over the first 2 years of life, and two thirds of 2-, 3-, and 4-year-olds consumed treat foods a few days per week or more. Parent-reported barriers to establishing a healthy diet with young children included child behavioural factors (e.g., dislike of vegetables), parental influences (e.g., lack of time), family dynamics (e.g., influence of extended family) and external influences (e.g., external environment). Parents were most often interested in ways to modify child behaviour and information about child nutrition.

CONCLUSIONS

Parents cite child behavioural issues as a major barrier to establishing a healthy diet with young children. Behavioural interventions that provide parents with information and support on how to establish a healthy diet with young children, as opposed to educational interventions focusing mainly on what children should be eating, may better meet families' needs.

Nurturing children's development through healthy eating and active living: Time for policies to support effective interventions in the context of responsive emotional support and early learning

Fostering the growth, development, health, and wellbeing of children is a global priority. The early childhood period presents a critical window to influence lifelong trajectories, however urgent multisectoral action is needed to ensure that families are adequately supported to nurture their children's growth and development. With a shared vision to give every child the best start in life, thus helping them reach their full developmental potential, we have formed the International Healthy Eating Active Living Matters (HEALing Matters) Alliance. Together, we form a global network of academics and practitioners working across child health and development, and who are dedicated to improving health equity for children and their families. Our goal is to ensure that all families are free from structural inequality and oppression and are empowered to nurture their children's growth and development through healthy eating and physical activity within the context of responsive emotional support, safety and security, and opportunities for early learning. To date, there have been disparate approaches to promoting these objectives across the health, community service, and education sectors. The crucial importance of our collective work is to bring these priorities for early childhood together through multisectoral interventions, and in so doing tackle head on siloed approaches. In this Policy paper, we draw upon extensive research and call for collective action to promote equity and foster positive developmental trajectories for all children. We call for the delivery of evidence-based programs, policies, and services that are co-designed to meet the needs of all children and families and address structural and systemic inequalities. Moving beyond the "what" is needed to foster the best start to life for all children, we provide recommendations of "how" we can do this. Such collective impact will facilitate intergenerational progression that builds human capital in future generations.

Associations between Emotion Regulation, Feeding Practices, and Preschoolers' Food Consumption

Previous research identified emotion dysregulation, non-responsive feeding practices, and unhealthy food consumption as risk factors for childhood obesity. However, little is known about the relationships between these factors. This study examined associations between children’s emotion regulation, parental feeding practices, and children’s food consumption. The sample consisted of 163 mothers of children aged 3–5 years. Mothers completed the Emotion Regulation Checklist, the Child Feeding Questionnaire, and the Child Health Section from the Parent Interview of the Early Childhood Longitudinal Study-B to assess model variables. Results showed that healthy food consumption was associated with higher emotion regulation abilities, higher monitoring, and lower pressure to eat. For unhealthy food consumption, the associations were in opposite directions. Higher emotion regulation abilities were also associated with higher monitoring, lower pressure to eat, and lower restriction. For lability, the associations were in opposite directions. Regression analyses revealed that children’s lability, pressure to eat, and monitoring were significant predictors of children’s food consumption. These findings suggest that children’s emotion regulation and feeding practices are important determinants of children’s food consumption. Future longitudinal studies that examine bidirectional associations between children’s emotion regulation, parental feeding practices, children’s food consumption, and potential mechanisms accounting for these associations are needed.

Associations Among Food Delay of Gratification, Cognitive Measures, and Environment in a Community Preschool Sample

Much of the work on the development of appetite self-regulation in early childhood employs tasks assessing Delay of Gratification (DoG). While this skill is thought to rely on "cool" cognitive processes like effortful control, executive functioning, and self-regulation, demonstration of how laboratory measures of food DoG relate to common assessments of those cognitive processes in community samples of children is needed. This study presents secondary data investigating the associations between two laboratory tasks of food DoG, the Snack Delay and Tongue Tasks, and an array of laboratory and parent-report cognitive measures in a sample of 88 children ages 3-6 (M age = 4.05, SD = 0.76), as well as how four measures of the child's environment were associated with food DoG. Results indicated that both measures of food DoG were positively correlated with performance on the cognitive tasks, with stronger associations observed for the Tongue Task. Family income was positively associated with food DoG as measured by the Tongue Task, and child negative life events in the past year were negatively correlated with food DoG as measured by the Snack Delay Task. These findings present the pattern of associations between cognitive tasks and food DoG, the development of which may be meaningfully affected by specific aspects of family environment.

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.

Associations between infant and maternal characteristics measured at child age 5 months and maternal feeding styles and practices up to child age two years

Facilitating positive feeding practices from infancy may be an important strategy to prevent childhood overweight and obesity. Since the feeding situation early in life constitutes a bidirectional relationship, it is important to understand the impact of both maternal and infant characteristics on maternal feeding practices to intervene in a customized and tailored way. Few studies have concurrently examined associations between maternal and infant characteristics in relation to early maternal feeding practices. The aim of the present study was to explore potential associations between infant and maternal characteristics measured at child age five months, and maternal feeding styles and practices during the child’s first two years. Cross-sectional data from a Norwegian randomized controlled trial in which participants responded to questionnaires at child age 5 months (n = 474), 12 months (n = 293) and 24 months (n = 185) were used to explore potential associations. All maternal and child predictor variables were collected at child age five months. Maternal feeding styles and practices were mapped using subscales from the Infant Feeding Questionnaire at child age 5 and 12 months and the Child Feeding Questionnaire and the Parental Feeding Style Questionnaire at child age 24 months. The subscale-scores were split into roughly equal tertiles, and the upper or lower tertile for the outcome of interest were used to create binary outcome variables. Multivariable binary logistic regression models were conducted for each outcome. We found that maternal education and mental health symptoms as well as infant weight, temperament and feeding mode were associated with maternal feeding styles and practices over time. Our findings indicate that risk factors which may have long-term implications for child weight and health outcomes can be identified early. Larger, population-based studies with a longitudinal design are needed to further explore these pathways.

Precision Food Parenting: A Proposed Conceptual Model and Research Agenda

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

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.

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.

Barriers and enablers to caregivers' responsive feeding behaviour: A systematic review to inform childhood obesity prevention

Responsive infant feeding is a critical component of childhood obesity prevention. However, there is little guidance for caregivers on how to do this successfully. The first step to developing an intervention to promote responsive feeding is to systematically identify its barriers and enablers. Searches were conducted in CINAHL, Cochrane Library, Medline, Embase, PubMed, PsycINFO, Maternity, and Infant Care from inception to November 2020. All study designs were included if they reported a barrier or enabler to responsive feeding during the first 2 years of life. We used a "best fit" framework synthesis, with the Capacity, Opportunity, Motivation, and Behaviour (COM-B) model. The Mixed Method Appraisal Tool (MMAT) was used to assess study quality. Forty-three studies were included in the review. Barriers (n = 36) and enablers (n = 21) were identified across five COM-B domains: psychological capacity, physical and social opportunity, and reflective and automatic motivation. Enablers were recognition of infant feeding cues, feeding knowledge and family and friends. Caregiver attitude toward control of feeding was a barrier, together with health care professional advice about formula feeding and breastfeeding expectation. These barriers and enablers provide a comprehensive evidence base to guide intervention development to improve responsive feeding and prevent obesity across individual and population levels.

Targeting Parenting Quality to Reduce Early Life Adversity Impacts on Lifespan Cardiometabolic Risk

Mounting evidence that early life adversity (ELA) exposures confer risk for cardiometabolic disease over the lifespan motivated this narrative review to examine parenting quality as a potential intervention target to reduce ELA exposures or mitigate their impact as a way of reducing or preventing cardiometabolic disease. We describe findings from the limited number of family-based intervention studies in ELA-exposed children that have tested parenting impacts on cardiometabolic health outcomes. We then describe the implications of this work and make recommendations for future research that will move this field forward.

Caregivers' Perceived Emotional and Feeding Responsiveness toward Preschool Children: Associations and Paths of Influence

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. The results showed that mothers' supportive emotion responses (e.g., problem-focused, emotion-focused, and expressive encouragement reactions) tend to be positively associated with responsive feeding practices (e.g., encouraging, modelling, and teaching healthy food-related behaviors). Instead, mothers' unsupportive responses (e.g., distress, punitive and minimization reactions) tend to be positively associated with nonresponsive feeding practices (e.g., food as reward or to regulate emotions, and pressure to eat) and negatively associated with responsive feeding practices. Our results suggest that emotional and feeding responsiveness may be intertwined and that differences in parent's emotional responsiveness may translate into differences in their feeding styles, setting the stage for parents' use of positive vs. negative feeding practices.

Early Life Adversity and Pubertal Timing: Implications for Cardiometabolic Health

OBJECTIVE

To identify early life adversity (ELA) risk factors for earlier pubertal timing, itself a risk factor for poor cardiometabolic health, and to determine whether such ELA-related risk may be mediated by pre-pubertal body mass index (BMI).

METHODS

Subjects included 426 female participants in a prospective birth cohort study, the NICHD Study of Early Child Care and Youth Development. Survival analysis models were fit to examine ELA exposures, representing childhood socioeconomic status (SES), maternal sensitivity, mother-child attachment, and negative life events, along with child health indicators and covariates, in relation to pubertal timing outcomes, including age at menarche and ages at Tanner stage II for breast and pubic hair development.

RESULTS

Higher childhood SES emerged as an independent predictor of older age at menarche, showing each one standard deviation increase in childhood SES corresponded to a 1.3% increase in age at menarche (factor change = 1.013; 1.003-1.022; p < .01), but did not predict breast or pubic hair development (ps > .05). In mediation analyses, indirect (mediated) effects of mother-child attachment on the pubertal timing outcomes, via pre-pubertal BMI, were all statistically significant (ps < .05).

CONCLUSIONS

Higher childhood SES predicted directly, and secure (vs. insecure) mother-child attachment predicted indirectly (via pre-pubertal BMI), later pubertal timing, suggesting these factors may protect girls from earlier pubertal development. By extension, clinical implications are that intervention strategies designed to lessen ELA- and pre-pubertal obesity-related risk may be effective in remediating life course pathways linking ELA, accelerated pubertal development, and cardiometabolic risk.

Binge Eating and Addictive-Like Behaviours in Males and Females

INTRODUCTION

Binge eating is a common behaviour that is strongly linked to both obesity and eating disorder. There is evidence that binge eating commonly co-occurs with other problematic and addictive-like behaviours; however, this has not been explored systematically. The present study aimed to examine the relationship between binge eating, body weight, disordered eating behaviours and associated addictive-like behaviours, with particular attention paid to gender differences.

METHOD

A community sample (N = 500; 75% female, M_age = 32.5 years) reported disordered eating behaviours (i.e. binge eating, purging, restriction of eating, compulsive exercise), body mass index (BMI), food addiction, starvation addiction, exercise dependence, tobacco use and alcohol consumption.

RESULTS

42% of females and 21% of males reported binge eating during the past four weeks. Binge eating was significantly associated with all investigated behaviours in females, and with purging, compulsive exercise and overweight/obesity in males. Controlling for BMI, self-starvation predicted binge eating in males (OR = 1.07), while food addiction (OR = 1.73) and alcohol dependence (OR = 1.11) predicted binge eating in females.

CONCLUSIONS

The multiple associations between binge eating and addictive-like behaviors supports broad screening and generalized prevention efforts. Prevention efforts should reflect gender differences.

Reframing the early childhood obesity prevention narrative through an equitable nurturing approach

High‐quality mother–child interactions during the first 2,000 days, from conception to age 5 years, are considered crucial for preventing obesity development during early life stages. However, mother–child dyads interact within and are influenced by broader socio‐ecological contexts involved in shaping child development outcomes, including nutrition. Hence, the coexistence of both undernutrition and obesity has been noted in inequitable social conditions, with drivers of undernutrition and overnutrition in children sharing common elements, such as poverty and food insecurity. To date, a holistic life‐course approach to childhood obesity prevention that includes an equitable developmental perspective has not emerged. The World Health Organization (WHO) Nurturing Care Framework provides the foundation for reframing the narrative to understand childhood obesity through the lens of an equitable nurturing care approach to child development from a life‐course perspective. In this perspective, we outline our rationale for reframing the childhood narrative by integrating an equitable nurturing care approach to childhood obesity prevention. Four key elements of reframing the narrative include: (a) extending the focus from the current 1,000 to 2,000 days (conception to 5 years); (b) highlighting the importance of nurturing mutually responsive child‐caregiver connections to age 5; (c) recognition of racism and related stressors, not solely race/ethnicity, as part of adverse child experiences and social determinants of obesity; and (d) addressing equity by codesigning interventions with socially marginalized families and communities. An equitable, asset‐based engagement of families and communities could drive the transformation of policies, systems and social conditions to prevent childhood obesity.

A laboratory-based assessment of mother-child snack food selections and child snack food consumption: Associations with observed and maternal self-report of child feeding practices

This study explored how mothers' observed and self-reported child feeding practices (child control over food choices, encouragement of balance and variety, and teaching about nutrition) were associated with mother-child snack food selections and child snack food consumption in a laboratory setting. Mothers (N = 107) and their 4.5-year-old children (52% female) selected up to 5 snack foods (out of 9 snack foods: 6 higher-energy-density [ED] and 3 lower-ED) for optional child consumption throughout a one-hour laboratory visit. Mothers' in-the-moment child feeding practices during the snack food selection task were coded using observational coding schemes, and mothers' global child feeding practices (i.e., across meals and snacking occasions) were self-reported using the Comprehensive Feeding Practices Questionnaire (Musher-Eizenman & Holub, 2007). Results of multiple linear regression analyses with covariates showed that higher-ED snack food selections were positively associated with observed child control over food choices (B = 0.35, SE = 0.12, p = .006) and self-reported teaching about nutrition (B = 0.49, SE = 0.19, p = .010), and negatively associated with self-reported encouragement of balance and variety (B = -0.66, SE = 0.24, p = .007). Lower-ED snack food selections were positively associated with self-reported encouragement of balance and variety (B = 0.53, SE = 0.20, p = .008). Child consumption of higher-ED or lower-ED snack foods were not significantly associated with mothers' child feeding practices (observed or self-reported). We discuss the implications of these findings for future research on children's snack food selection and consumption.

Maternal attachment style, sensitivity, and infant obesity risk in low-income, Latino families

Disparities in childhood obesity highlight the need for research to identify its early predictors in high-risk populations, such as low-income, Latino families. In the current study, the first of its kind in a low-income Latino sample (N = 55; M _{child age} = 12.74 months, SD = 3.96), we investigated whether mothers' self-reported attachment style predicted their infants' weight-for-length (WFL; an early indicator of childhood obesity). We also explored whether observed maternal sensitivity, coded from a video-recorded semi-structured play assessment, mediated this association. We found a significant direct effect of maternal attachment style on infants' WFL z-scores (c' = -0.68, SE = 0.22, p = .004). Infants of mothers who classified themselves as secure had lower WFL z-scores than infants of insecure mothers (avoidant or anxious). Maternal sensitivity did not mediate this association, but was positively associated with infant WFL z-scores. We discuss implications of these findings for future research.

A core outcome set for trials of infant-feeding interventions to prevent childhood obesity

BACKGROUND

Standardisation of outcomes measured and reported in trials of infant-feeding interventions to prevent childhood obesity is essential to evaluate and synthesise intervention effects. The aim of this study is to develop an infant-feeding core outcome set for use in randomised trials of infant-feeding interventions, with children ≤1 year old, to prevent childhood obesity.

METHODS

Core outcome set development followed four stages: (1) systematic review of outcomes reported in the extant literature; (2) meeting with national and international stakeholders to discuss and clarify identified outcomes; (3) e-Delphi study with national and international stakeholders to prioritise outcomes; (4) meeting with national and international stakeholders to reach consensus on outcomes. Stakeholders in stages 2-4 were paediatricians, general practitioners, nurses, midwives, non-clinician researchers, parents, dieticians, nutritionists, and childcare providers.

RESULTS

Twenty-six outcomes were identified for inclusion in the core outcome set. These were grouped in nine outcome domains: 'breastfeeding and formula feeding', 'introduction of solids', 'parent feeding practices and styles', 'parent knowledge and beliefs', 'practical feeding', 'food environment', 'dietary intake', 'perceptions of infant behaviour and preferences', and 'child weight'.

CONCLUSIONS

The core outcome set identified in this study is the minimum that should be measured and reported in trials of infant-feeding interventions to prevent childhood obesity. This standardisation of outcomes will enable more comprehensive examination and synthesis of the effects of infant-feeding interventions to prevent childhood obesity.
