RESUMO

Given prior literature focused on the Developmental Origins of Health and Disease framework, there is strong rationale to hypothesize that reducing depression in the prenatal period will cause improvements in offspring cardiometabolic health. The current review outlines evidence that prenatal depression is associated with offspring cardiometabolic risk and health behaviors. We review evidence of these associations in humans and in nonhuman animals at multiple developmental periods, from the prenatal period (maternal preeclampsia, gestational diabetes), neonatal period (preterm birth, small size at birth), infancy (rapid weight gain), childhood and adolescence (high blood pressure, impaired glucose-insulin homeostasis, unfavorable lipid profiles, abdominal obesity), and into adulthood (diabetes, cardiovascular disease). In addition to these cardiometabolic outcomes, we focus on health behaviors associated with cardiometabolic risk, such as child eating behaviors, diet, physical activity, and sleep health. Our review focuses on child behaviors (e.g., emotional eating, preference for highly palatable foods, short sleep duration) and parenting behaviors (e.g., pressuring child to eat, modeling of health behaviors). These changes in health behaviors may be detected before changes to cardiometabolic outcomes, which may allow for early identification of and prevention for children at risk for poor adult cardiometabolic outcomes. We also discuss the methods of the ongoing Care Project, which is a randomized clinical trial to test whether reducing prenatal maternal depression improves offspring's cardiometabolic health and health behaviors in preschool. The goal of this review and the Care Project are to inform future research, interventions, and policies that support prenatal mental health and offspring cardiometabolic health.

RESUMO

Obesity in children remains a major public health problem, with the current prevalence in youth ages 2-19 years estimated to be 19.7%. Despite progress in identifying risk factors, current models do not accurately predict development of obesity in early childhood. There is also substantial individual variability in response to a given intervention that is not well understood. On April 29-30, 2021, the National Institutes of Health convened a virtual workshop on "Understanding Risk and Causal Mechanisms for Developing Obesity in Infants and Young Children." The workshop brought together scientists from diverse disciplines to discuss (1) what is known regarding epidemiology and underlying biological and behavioral mechanisms for rapid weight gain and development of obesity and (2) what new approaches can improve risk prediction and gain novel insights into causes of obesity in early life. Participants identified gaps and opportunities for future research to advance understanding of risk and underlying mechanisms for development of obesity in early life. It was emphasized that future studies will require multi-disciplinary efforts across basic, behavioral, and clinical sciences. An exposome framework is needed to elucidate how behavioral, biological, and environmental risk factors interact. Use of novel statistical methods may provide greater insights into causal mechanisms.

RESUMO

Examining typical developmental trajectories of infant eating behaviors, correlates of those trajectories, and cross-lagged associations between eating behaviors and anthropometry, is important to understand the etiology of these behaviors and their relevance to growth early in the lifespan. Mothers (N = 276) completed the Baby Eating Behavior Questionnaire (BEBQ) and infant anthropometrics were measured at ages 1, 2, 4, 6, and 10 months. Infant and maternal characteristics were collected by maternal report. Trajectories of eating behaviors were identified using latent class growth modeling and bivariate analyses examined associations of infant eating behavior trajectory membership with infant and maternal characteristics. Cross-lagged analyses examined associations between BEBQ subscales and infant weight-for-length z-score. Infant eating behavior trajectories included: Consistently High (62%) and Consistently Moderate (38%) Enjoyment of Food; Consistently High (9%), Moderate & Decreasing (43%), and Low & Decreasing (48%) Food Responsiveness; and Consistently High (62%) and Moderate & Decreasing (38%) General Appetite. Trajectory group membership was not associated with infant sex, gestational age, birthweight, or having been exclusively fed breastmilk at 2 months. Consistently High trajectories for Enjoyment of Food, Food Responsiveness, and General Appetite were associated with maternal demographic markers of psychosocial risk (e.g., lower maternal age and educational attainment). Food Responsiveness and General Appetite tracked strongly across infancy within individuals. Cross-lagged associations of Enjoyment of Food, Food Responsiveness, and General Appetite with weight-for-length z-score across infancy were generally null. Much additional work is needed to understand eating behaviors in infancy, their development, and their etiology. Further understanding of infant eating behaviors will provide the basis for future interventions to improve life course nutrition, growth, and health.

RESUMO

The early postpartum period is a sensitive time for understanding women's high-risk eating (i.e., eating behavior associated with negative health outcomes) given potential long-term eating behavior implications for infants. Food addiction and dietary restraint are two high-risk eating phenotypes associated with long-term negative health outcomes that have been theoretically linked. Yet, no research has considered how much these constructs overlap during the early postpartum period. The present study sought to characterize these two high-risk eating phenotypes in postpartum women to examine whether these are distinct constructs with specific etiologies and to inform future targets of intervention. Women (N = 277) in the early postpartum period reported on high-risk eating, childhood trauma exposure, depression symptoms, and pre-pregnancy weight. Women's height was measured and pre-pregnancy BMI was calculated. We conducted bivariate correlations and path analysis to characterize the relationship between food addiction and dietary restraint, controlling for pre-pregnancy BMI. Results showed that food addiction and dietary restraint were not significantly associated and that women's childhood trauma exposure and postpartum depression were associated with food addiction but not dietary restraint. Sequential mediation revealed that higher levels of childhood trauma exposure were associated with worse postpartum depression and, in turn, greater food addiction during the early postpartum period. Findings suggest that food addiction and dietary restraint have distinct psychosocial predictors and etiological pathways, which suggests important construct validity differences between the two high-risk eating phenotypes. Interventions seeking to address food addiction in postpartum women and mitigate the impact of this high-risk eating phenotype on the next generation may benefit from treating postpartum depression, especially in women with histories of childhood trauma exposure.

RESUMO

Importance: The capacity for regulation of energy intake (REI) to match energy needs is thought to contribute to differences in weight gain, and preventing excess infant weight gain is a priority. Objective: To determine capacity for REI across infancy. Design, Setting, and Participants: For this cohort study, a convenience sample of mother-infant dyads was recruited from the community in Michigan between 2015 and 2019. Inclusion criteria were healthy, full-term infants with weight appropriate for gestational age; biological mothers who were 18 years or older, English speaking, and a legal and custodial guardian; and infant having had consumed 2 oz or more in 1 feeding from an artificial nipple at least once per week. Infants were followed in the home setting with staff support for up to 12 months. Interventions: Mother-infant dyads participated at infant age 1, 2.5, 5, 7, 10, and 12 months. In the intervention condition, mothers offered a feeding every hour for 6 hours. In the control condition, mothers fed infants as they typically would for 6 hours. Intake was recorded and kilocalories calculated. Main Outcomes and Measures: Capacity for REI was indexed as the difference in intake in kilocalories per kilogram of body weight (intervention minus control condition); a value of 0 indicated perfect REI. Maternal and infant characteristics were obtained by questionnaire, and anthropometry was measured. Using multiple imputation, the intercept and slope for difference in kilocalories per kilogram across the 6 age points were estimated using mixed models accounting for repeated measures within participants. Statistical analyses were conducted between September 2021 and February 2023. Results: The sample included 175 infants (87 [49.71%] female, 88 [50.29%] male; 494 pairs of intervention and control conditions and 4630 feedings). The mean (SD) 12-month weight-for-age z score was 0.1 (0.8). Mean (SD) gestational age as 39.55 (1.05) weeks, and mean (SD) birth weight was 3.43 (0.41) kg. Mean (SD) breastfeeding duration for those who reported stopping by 12 months was 17.83 (12.03) weeks. As designed, the intervention (compared with control) condition included more feedings at shorter intervals. After collapsing the data across age points in a mixed model accounting for repeated measures within participants, the REI estimate at 1 month differed from 0. On average, infants ate 5.21 kcal/kg (95% CI, 2.89-7.54 kcal/kg) more in the frequent feeding intervention condition than in the ad lib feeding control condition. This difference did not significantly change over 12 months of infancy (REI slope = -0.01 kcal/kg per month; 95% CI, -0.02 to 0.03 kcal/kg per month). Conclusions and Relevance: The study's findings suggested that, on average, when offered more frequent feedings, healthy, full-term infants may overeat. The results provide support for responsive feeding as a strategy for preventing excess infant weight gain.

RESUMO

This study sought to identify sucking profiles among healthy, full-term infants and assess their predictive value for future weight gain and eating behaviors. Pressure waves of infant sucking were captured during a typical feeding at age 4 months and quantified via 14 metrics. Anthropometry was measured at 4 and 12 months, and eating behaviors were measured by parent report via the Children's Eating Behavior Questionnaire-Toddler (CEBQ-T) at 12 months. Sucking profiles were created using a clustering approach on the pressure wave metrics, and utility of these profiles was assessed for predicting which infants will have weight-for-age (WFA) percentile changes from ages 4-12 months that exceed thresholds of 5, 10, and 15 percentiles, and for estimating each CEBQ-T subscale score. Among 114 infants, three sucking profiles were identified: Vigorous (51%), Capable (28%), and Leisurely (21%). Sucking profiles were found to improve estimation of change in WFA from 4 to 12 months and 12-month maternal-reported eating behaviors above infant sex, race/ethnicity, birthweight, gestational age, and pre-pregnancy body mass index alone. Infants with a Vigorous sucking profile gained significantly more weight during the study period than infants with a Leisurely profile. Infant sucking characteristics may aid in predicting which infants may be at greater risk of obesity, and therefore sucking profiles deserve more investigation.

RESUMO

Maternal food addiction, dietary restraint, and pre-pregnancy body mass index (BMI) are associated with high-risk eating behaviors and weight characteristics in children and adolescents. However, little is known about how these maternal factors are associated with individual differences in eating behaviors and risk for overweight in infancy. In a sample of 204 infant-mother dyads, maternal food addiction, dietary restraint and pre-pregnancy BMI were assessed using maternal self-report measures. Infant eating behaviors (as measured by maternal report), objectively measured hedonic response to sucrose, and anthropometry were measured at 4 months of age. Separate linear regression analyses were used to test for associations between maternal risk factors and infant eating behaviors and risk for overweight. Maternal food addiction was associated with increased risk for infant overweight based on World Health Organization criteria. Maternal dietary restraint was negatively associated with maternal report of infant appetite, but positively associated with objectively measured infant hedonic response to sucrose. Maternal pre-pregnancy BMI was positively associated with maternal report of infant appetite. Maternal food addiction, dietary restraint, and pre-pregnancy BMI are each associated with distinct eating behaviors and risk for overweight in early infancy. Additional research is needed to identify the mechanistic pathways driving these distinct associations between maternal factors and infant eating behaviors and risk for overweight. Further, it will be important to investigate whether these infant characteristics predict the development of future high-risk eating behaviors or excessive weight gain later in life.

RESUMO

OBJECTIVE: To determine the effect of a bundled intervention (home meal delivery and provision of cooking/serving resources) on preschoolers' body mass index z-score (BMIz), dietary quality, and family meal frequency. METHODS: Participants (299 families; mean child age 4.4 years, 47% male, 55% White, 18% Black, 27% Hispanic or other race and ethnicity, and 25% were overweight or obese) were randomized to a control group or to provision of cooking/serving resources plus home meal delivery for 12 weeks (meals provided by Meals on Wheels [MOW cohort, n = 83] or a commercial service [COM cohort, n = 216]). Outcomes were child dietary quality, family meal frequency, and child BMIz. RESULTS: The intervention increased dinnertime intake of red and orange vegetables in the full sample (MOW cohort+COM cohort) (0.10 pre- to 0.15 cup equivalents (CE) post-in the intervention group vs 0.10 pre- to 0.09 post- in the control group; P = .01) and the COM cohort (0.11 pre- to 0.17 CE post- vs 0.11 pre- to 0.09 post-; P = .002), and typical daily dietary intake of fruit and fruit juice in the MOW cohort (1.50 CE pre- to 1.66 post- vs 1.48 pre- to 1.19 post-; P = .05). The intervention did not change meal frequency or BMIz. CONCLUSIONS: Short-term home meal delivery with provision of cooking/serving resources improved dietary quality among preschool-aged children but did not change meal frequency or BMIz. Expansion of Meals on Wheels programs to preschool-aged children may be a promising intervention to improve dietary quality. Family meals, when already frequent, are not further increased by reducing the burden of meal preparation.

RESUMO

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.

RESUMO

BACKGROUND: Individual differences in eating behaviors among young children are well-established, but the extent to which behaviors aggregate within individuals to form distinct eating behavior profiles remains unknown. Our objectives were to identify eating behavior profiles among preschool-aged children and evaluate associations with temperament and weight. METHODS: A secondary, cross-sectional analysis of baseline data from 2 cohort studies was conducted involving 1004 children aged 3-4 years and their parents with low-income backgrounds. Children's eating behaviors and temperament were assessed by parental report. Body mass index z-scores and weight status were calculated using measured heights and weights. Latent profile analysis (LPA) was used to generate profiles and bivariate analyses were used to evaluate associations with temperament and weight status. RESULTS: LPA revealed the presence of 3 eating behavior profiles among children. Children with High Food Approach profiles (21.2%) had lower temperamental inhibitory control and the highest percent of children with obesity relative to the other profiles. Children with High Food Avoidant profiles (35.6%) had lower temperamental impulsivity and lower BMI z-scores relative to the other profiles, whereas children with Moderate Eating profiles (intermediary levels of all behaviors; 43.2%) had higher temperamental inhibitory control and lower anger/frustration, than other profiles. CONCLUSIONS: Young children's eating behaviors appear to aggregate within individuals to form empirically distinct profiles reflecting food approach, food avoidance, and moderate approaches to eating that are differentiated by aspects of temperament and weight. Future work should seek to understand the extent to which health promotion and obesity prevention approaches should be tailored to take into account children's fundamental dispositions towards eating.

RESUMO

The first week after birth is a critical time for the establishment of microbial communities for infants. Preterm infants face unique environmental impacts on their newly acquired microbiomes, including increased incidence of cesarean section delivery and exposure to antibiotics as well as delayed enteral feeding and reduced human interaction during their intensive care unit stay. Using contextualized paired metabolomics and 16S sequencing data, the development of the gut, skin, and oral microbiomes of infants is profiled daily for the first week after birth, and it is found that the skin microbiome appears robust to early life perturbation, while direct exposure of infants to antibiotics, rather than presumed maternal transmission, delays microbiome development and prevents the early differentiation based on body site regardless of delivery mode. Metabolomic analyses identify the development of all gut metabolomes of preterm infants toward full-term infant profiles, but a significant increase of primary bile acid metabolism only in the non-antibiotic treated vaginally birthed late preterm infants. This study provides a framework for future multi-omic, multibody site analyses on these high-risk preterm infant populations and suggests opportunities for monitoring and intervention, with infant antibiotic exposure as the primary driver of delays in microbiome development.

RESUMO

Although children frequently engage in creative activities (in which they make foods and objects by hand), the development and scope of children's thinking about handmade items is largely unexplored. In the present studies, we examined whether 4- to 12-year-old children at a local children's museum (54% girls, 46% boys; 51% White, 11% Asian/Asian American, 10% more than 1 group, 4% Latinx, 3% Black/African American, 18% did not report race/ethnicity) would expect other people to prefer handmade over factory-made items, including foods and nonfoods. In Experiments 1 (n = 124) and 2 (n = 122), participants expected a child character to prefer items the character made themselves and items made by the character's parent or a local person. However, this expectation did not persist at all costs: When considering imperfect handmade items in Experiment 3 (n = 122), children demonstrated a handmade preference when considering nonfoods made by a parent but demonstrated a factory-made preference when considering foods made by a parent. Children's explanations were associated with their choices: When children's explanations referred to emotions or relationships, they were more likely to select handmade items. When children referred to item features, they were more likely to select factory-made items. Across studies, we observed persistent age and gender effects: Children's handmade preference increased with child age and girls demonstrated a more robust handmade preference than boys. These findings highlight children's developing and nuanced reasoning about object value. At an early age, children consider who made an object as a contributor to its value.

RESUMO

Objective: Eating behavior regulation emerges during early development and involves general self-regulation (emotional, behavioral), appetite regulation (homeostatic metabolic need) and appetite self-regulation (including both Bottom-Up Food Approach and Bottom-Up Food Avoidance and top-down purposeful self-control of eating). Limited research has investigated developmental trajectories of the regulation of eating behavior before the preschool years. The current study used a novel food delay task to assess infant distress as an early emerging marker of eating behavior regulation constructs across early infancy and examine associations with amount of milk consumed. Method: Mother-infant dyads (n = 179) completed the Ability to Delay Gratification for Food in Infants Task (ATDG-FIT) at 2 weeks, 8 weeks, and 16 weeks of age. The ATDG-FIT required infants to wait before being fed while their bottle was present, but not accessible (3-min Pre-Feeding Delay). After this, the infant was fed for 1 min, then the feeding was paused for 30 s (Mid-Feeding Delay). Infant distress was coded during each feeding delay period and the amount of milk consumed was measured. Results: The mean proportion of distress during the Pre-Feeding Delay period decreased from 8 to 16 weeks of age (F(2,230) = 15.02, p < 0.001), whereas the mean proportion of distress during the Mid-Feeding Delay increased from 2 to 8 weeks of age (F(2,230) = 27.04, p < 0.001). There was a positive interaction between distress during Mid-Feeding Delay and infant age predicting the amount consumed in the protocol (ß = 0.30, p = 0.022), suggesting that the association between distress during this part of the task and amount consumed strengthens as infants get older. Conclusion: The ATDG-FIT may be an effective method to assess emerging eating behavior regulation constructs during early infancy.

RESUMO

We aimed to test main, additive, interactive effects, and feasibility of all possible combinations of six intervention components implemented for 8 weeks (Cooking/Serving Resources; Meal Delivery; Ingredient Delivery; Community Kitchen; Nutrition Education; Cooking Demonstrations). Primary outcomes were family meal frequency and preschoolers' dietary quality; secondary outcomes included family meal preparation type, meal preparation barriers, family functioning, and kitchen inventory adequacy. All possible intervention combinations were tested using a randomized factorial trial design in the first phase of a Multiphase Optimization Strategy (MOST). Feasibility was assessed via attendance, delivery logs, and satisfaction. Parent-reported data collection included: socio-demographics, frequency and type of family meals; preschooler dietary intake; perceived barriers to meal planning and preparation; assessment of family functioning; and a kitchen inventory of materials generally needed for meal preparation. Participants (n = 499) were recruited at two Head Start agencies in mid-Michigan with data collection and delivery of some intervention components in participants' homes. Promising intervention bundles were identified by evaluating pre-to post-intervention effect sizes. The combination of Cooking/Serving Resources and Meal Delivery increased family meal frequency (Cohen's d = 0.17), cooking dinner from scratch (d = 0.21), prioritization of family meals (d = 0.23), and kitchen inventory (d = 0.46) and decreased use/consumption of ready-made (d = -0.18) and fast foods (d = -0.23). Effects on diet quality were in the expected direction but effect sizes were negligible. Community Kitchen, Nutrition Education, and Cooking Demonstration showed poor feasibility due to low attendance while Ingredient Delivery was infeasible due to staffing challenges related to its labor intensity. Additionally, although not one of our pre-specified outcomes, Cooking/Serving Resources (RR = 0.74) and Meal Delivery (RR = 0.73) each decreased food insecurity. Cooking/Serving Resources combined with Meal Delivery showed promise as a strategy for increasing family meal frequency.

RESUMO

Adolescence is a period of increased risk-taking behavior, thought to be driven, in part, by heightened reward sensitivity. One challenge of studying reward processing in the field of developmental neuroscience is finding a task that activates reward circuitry, and is short, not too complex, and engaging for youth of a wide variety of ages and socioeconomic backgrounds. In the present study, we tested a brief child-friendly reward task for activating reward circuitry in two independent samples of youth ages 7-19 years old enriched for poverty (study 1: n = 464; study 2: n = 27). The reward task robustly activated the ventral striatum, with activation decreasing from early to mid-adolescence and increasing from mid- to late adolescence in response to reward. This response did not vary by gender, pubertal development, or income-to-needs ratio, making the task applicable for a wide variety of populations. Additionally, ventral striatum activation to the task did not differ between youth who did and did not expect to receive a prize at the end of the task, indicating that an outcome of points alone may be enough to engage reward circuitry. Thus, this reward task is effective for studying reward processing in youth from different socioeconomic backgrounds.

RESUMO

OBJECTIVE: To examine whether patterns of body mass index (BMI) percentile gains across childhood predict BMI percentile, overweight and obesity, waist circumference, and elevated or prehypertensive blood pressure at age 15. METHODS: Trained technicians in the Study of Early Child Care and Youth Development assessed children's weight and height from birth to 15 years and waist circumference and blood pressure at age 15 (n = 1132). Children's BMI percentile trajectories from age 2 to age 13 along with 28 demographic and social covariates were used to predict BMI percentile, waist circumference, overweight, obesity, and elevated or prehypertensive blood pressure. Linear and logistic regressions were used to predict BMI percentile, overweight, obesity, waist circumference, and elevated or prehypertensive blood pressure. RESULTS: Children were classified into one"?>1 of 4four"?> BMI percentile trajectories: "low stable" (28.4%), "low-to-high" (11.8%), "median stable" (29.0%), and "high rising" (30.7%). Children in trajectory classes characterized by persistent above average BMI percentile or by periods of rapid BMI percentile gains were more likely than their peers to experience poor weight and elevated or prehypertensive outcomes in adolescence. Trajectory class membership explained substantially more variance in adolescent health outcomes than demographic covariates alone. Estimated maternal BMI was a key independent predictor of adolescent outcomes. CONCLUSIONS: Different patterns of BMI percentile gains, namely those with rapid gains or persistently above average BMI percentile, from ages 2 to 13 predicted weight, waist circumference, and elevated or prehypertensive blood pressure at age 15, above and beyond demographic and social characteristics.

RESUMO

OBJECTIVE: To experimentally test weight stigma and weight stigma by association in a parent-child relationship using a large, community-based sample. METHODS: We conducted a randomized experiment on Amazon Mechanical Turk using an online survey. Participants were randomly assigned to view a picture of a parent-child dyad, for which the parent and child's gender (male vs. female) and weight status (with obesity vs. without obesity) were manipulated. Participants read identical parenting descriptions that adhered to the American Academy of Pediatrics' parenting recommendations, then rated the parent's perceived effectiveness, helpfulness, and level of caring using a parenting questionnaire based on Barnhart et al (2013). RESULTS: Participants (N = 1862; Mage = 36.8 [11.2] years) rated parents of children with obesity as less effective compared to parents of children without obesity (P = .010) and parents with obesity as less effective compared to parents without obesity (P = .033). Participants also rated parents with obesity as less helpful compared to parents without obesity (P = .021). No differences emerged in perceived caring. Parenting evaluations did not differ across daughters versus sons or mothers versus fathers. CONCLUSIONS: Parents of children with obesity may experience weight stigma by association, which could have direct consequences for the parents, the children, and the parent-child relationship.

RESUMO

OBJECTIVE: Identify mothers' perceptions of how they talk about weight and body shape with their children and examine how approaches vary by mother and child characteristics. BACKGROUND: Youth who report that their parents talk with them about their weight experience poor health. However, very little is known about the content of these conversations. METHOD: Mothers and their 6- to 11-year-old children (N = 188 dyads) participated in a mixed-methods study. Themes in mothers' responses to the interview question "How do you talk to your child about weight or body shape?" were identified, and latent class analysis was used to characterize patterns of weight and shape talk. RESULTS: Seven themes of weight and shape talk were identified, including talking about "Healthy Habits" (39.9%), "Avoids Weight and Body Talk" (21.8%), and tells "Cautionary Tales" (18.6%). Three patterns emerged from themes: talk to promote health, avoid talking about weight and shape, and talk to build children's self-esteem. Mothers of children with obesity were more likely to talk to promote health versus other patterns. CONCLUSION: The content of family conversations about weight and shape is diverse. IMPLICATIONS FOR EMERGING IDEAS: Future research is needed to understand the impacts of specific ways parents talk about weight and shape.

RESUMO

The study of emotion regulation often addresses control of negative emotion. Researchers have proposed that affective balance is an indicator of emotion regulation that incorporates the role of positive emotion in the context of negative emotional experiences. Environmental and individual factors, such as family processes and biological stress regulation, are known to shape emotion regulation. The present study investigated whether child diurnal cortisol, an indicator of biological stress regulation, moderated the association between family routines and observed affective balance. Children (N = 222; M age = 4.70 years, SD = 0.60) from low-income households provided saliva samples to measure diurnal cortisol and completed a behavioral task designed to elicit negative emotions. Affective balance was defined as the difference score between the proportion of positive and negative emotional expressions displayed during the task. A higher affective balance score indicated greater positive compared with negative emotional displays. Simple slope analyses indicated that for children with a low morning cortisol intercept, more frequent family routines were associated with more affective balance. This pattern was not observed in children with average or high morning cortisol. Positive family routines may play an important role in shaping affective balance among children with disrupted cortisol levels from low-income backgrounds.
