Feeding under fire: Relations between parental stress hormones and controlling feeding behaviors.

Under stress, parents tend to use more controlling feeding behaviors toward their children (Berge et al., 2017; Doan et al., 2022; Loth et al., 2016). However, the majority of prior work focuses on subjective reports of stress, and there is a dearth of research examining parental physiological stress and its impact on feeding behaviors. In the current study, we examined how parental physiological stress reactivity would influence their feeding behaviors under mild stress in a lab-based setting. Parents (n = 83, 50 % females) and their children (59% female, Mage = 42 months, SD = 4.48) participated. Stress was induced using the Trier Social Stress Test in the laboratory (Kirshbaum et al., 1993). Salivary samples were collected at 4 time points during the visit to index stress reactivity and later assayed for cortisol and DHEA. Parent-child interactions during the anticipatory period of the stress test were observationally coded for parent use of controlling feeding behaviors. To examine whether parent stress physiology predicts their feeding behaviors, we ran a Poisson regression using income, parent ethnicity, parent sex (mom/dad), time of day, and DHEA/cortisol ratio as predictors of controlling feeding behavior. Latinx parents used less controlling feeding behaviors, b = -0.323, p = 0.041 than non-Latinx parents. Parents with a higher DHEA/Cortisol ratio were less likely to use controlling feeding behaviors, b = -0.231, p = 0.008. To our knowledge, this is the first study to show that for both mothers and fathers, DHEA relative to cortisol has a protective role in controlling feeding practices, and lends support to the role of acute stress reactivity in predicting behavioral outcomes.

Undoing mothers' avoidant coping with children's negative emotion: A randomized controlled trial of relational savoring.

Some mothers report using avoidant coping strategies (minimizing, punishing) in response to their young children's negative emotion, an aspect of insensitive parenting that places children at risk for emotional or behavioral dysregulation (Fabes et al., 2001) and insecure attachment (De Wolff & van Ijzendoorn, 1997). In prior work, an in-home attachment-based relational savoring (RS) intervention, administered over a month's time, positively affected maternal emotion and sensitive behavior with young children (Borelli et al., 2023); further, a one-time online RS protocol had greater impacts on emotion and relationship satisfaction for mothers with greater attachment avoidance (Burkhart et al., 2015). However, we do not yet know whether a brief, laboratory intervention impacts highly avoidant mothers' behavior with their children and not just their self-reports of satisfaction. Here, we examine whether mothers' endorsement of avoidant coping strategies moderates the effect of an RS versus active control intervention on mothers' use of emotion-coaching during an emotionally charged conversation with their child. Mothers (N = 122; Mage = 33.42, SD = 5.40) and their preschoolers (Mage = 41.80 months, SD = 4.65; 48.4% female) from diverse backgrounds (41% Latina, 40% White [non-Latina]; 42% under $60,000 annual income) participated. The interaction between condition and level of avoidant coping on mothers' emotion-coaching behaviors was significant. Mothers high in avoidant coping (top quartile) displayed better emotion-coaching during the emotion conversation if they had been in the RS condition. Savoring may be a valuable tool to promote effective emotion-coaching among parents most prone to avoid their children's negative emotion.

Cortisol and changes in depressive symptoms: The moderating role of DHEA.

Stress is associated with activation of the hypothalamus-adrenal-axis (HPA). Cortisol, a product of the HPA, is thought to predict depression. However, to date, the majority of studies investigating the cortisol-depression relationship have been cross-sectional and results have been mixed. One possible reason for these mixed findings, may be that many studies fail to consider the moderating role of dehydroepiandosterone (DHEA), which is released alongside cortisol and is thought to serve opposing functions. Therefore, the present study investigated the main and interactive effects of cortisol and DHEA on depressive symptoms. Salivary cortisol and DHEA were measured from saliva throughout the Trier Social Stress task for N = 417 participants at baseline. Participants reported on their depressive symptoms using the Beck Depression Inventory - II at both baseline and follow up (ranging from 1-20 months post baseline; M = 11.60, SD = 5.80) as well as general demographics. The lavaan package in R (version 0.6.11; Rosseel, 2012) was used to conduct multiple regression analyses with FIML to explore the relationships between these variables. Results demonstrated no main effect of cortisol or DHEA, but did show a significant interaction with DHEA. The relations between cortisol and depressive symptoms depended on levels of DHEA such that the relationship was positive at low and negative at high levels of DHEA, with the overall interaction significant (ß = -.22, p < .001, 95% CI = [-.333, -.115]). DHEA can act as a protective factor against depression when cortisol levels are high. This presents opportunities for future research on how to improve DHEA levels to potentially reduce depression.

Early life adversity and adolescent sleep problems during the COVID-19 pandemic.

The COVID-19 pandemic resulted in a reorganization of adolescents' routines, especially their sleep schedules. Utilising 175 caregiver-adolescent dyads, the current study examined associations of biological (e.g., prenatal substance use), environmental (e.g., poverty), and relational (e.g., child maltreatment) subtypes of early life adversity (ELA) with various components of adolescents' sleep across the first year of the COVID-19 pandemic. Relational ELA explained unique variance in adolescents' sleep disturbances, but not other sleep components, following short- and longer-term exposure to the COVID-19 pandemic. However, the direction of this association switched such that relational ELA predicted decreased sleep disturbances during the initial phase of the U.S. COVID-19 pandemic in spring 2020 beyond pre-pandemic levels, but, over time, contributed to increased sleep disturbances beyond early-pandemic levels as the pandemic extended into the winter of 2020.

Belonging Exacerbates the Relations Between Racial Climate Stress and Physiological Dysregulation.

OBJECTIVE: Belonging is often considered a buffer against the physical and emotional consequences of discrimination and racial climate stress Youth Soc. 48(5):649-72, 2016. However, recent research suggests that feelings of belonging toward an institution can be detrimental when an individual feels discriminated against by the same institution to which one feels a sense of connection J Behav Med. 44(4):571-8, 2021. Therefore, the present study aimed to investigate the moderating role of institutional belonging in the relationship between racial climate stress and health, as indexed by allostatic load (AL), a multi-system indicator of physiological dysregulation. METHODS: In a sample of Black and White college students (N = 150; White = 82; Black = 68), self-reported racial climate stress, institutional belonging, and various demographic variables were collected. An AL composite was also collected, comprised of six biological measures of the SAM system, HPA axis, cardiovascular system, and metabolic system. Multiple regression analyses were conducted to explore the relationships between these variables. RESULTS: Results demonstrated no main effect of racial climate stress on AL but did show a significant interaction between racial climate stress and belonging, such that the positive relationship between racial climate stress and AL was significant only for those who also felt high levels of institutional belonging (ß int = .05, p = .006, 95% CI = 0.01 - 0.08). CONCLUSIONS: Feeling a sense of belonging may have negative physiological consequences for those who experience racial climate stress in a college setting.

Parental warmth, adolescent emotion regulation, and adolescents' mental health during the COVID-19 pandemic.

Introduction: The United States (U.S.) Surgeon General Advisory has characterized the COVID-19 pandemic as a youth mental health crisis. Thus, elucidating factors affecting adolescents' mental health during the pandemic is important for supporting youth through current and future challenges. Parenting influences adolescents' ability to cope with stressors, and emotion regulation strategy use may underlie these effects. Methods: This longitudinal study of 206 adolescents (49% female; 46.6% Latine) from the U.S. evaluated pathways from perceived parental warmth and affection at age 12 to changes in adolescents' internalizing and externalizing problems from before the pandemic (age 14) to the initial phase of the U.S COVID-19 pandemic in Spring 2020 (age 15) through adolescents' pre-pandemic cognitive reappraisal and expressive suppression emotion regulation strategy use at age 14. Results: Parental warmth and affection predicted decreased internalizing, but not externalizing, problems during the initial phase of the pandemic, and this effect was explained by adolescents' reduced reliance on expressive suppression as an emotion regulation strategy. Conclusion: These findings illuminate parenting and emotion regulation strategy selection as modifiable processes to support adolescents' mental health in this crisis and beyond.

COVID-19 Pandemic and Changes in Children's Behavioral Problems: The Mediating Role of Maternal Depressive Symptoms.

The COVID-19 pandemic has been linked to a range of behavioral problems in children. To date, however, longitudinal studies with data prior to the pandemic are rare, and moreover, few studies have examined the family context. This is notable as evidence suggests that mothers were highly vulnerable to the effects of the pandemic, and stress proliferation models would argue that children's wellbeing are undoubtedly affected by maternal wellbeing. In the current investigation, we examine changes in maternal depressive symptoms and children's behavioral problems from prior to the pandemic to the first few months of COVID-19 in the U.S. The results suggest a significant increase in children's internalizing problems and maternal depressive symptoms. Consistent with stress proliferation models, the relationship between COVID-19-related stressors and children's behavioral problems were mediated by maternal mental health.

Mothers' intentions to vaccinate their children for COVID-19.

Parents' intentions to vaccinate their children is an important area of investigation in light of the COVID-19 pandemic. There is a growing body of research examining factors that influence parents' vaccine intentions. The current study investigated factors that would influence maternal intent to vaccinate their children for COVID-19, shortly before the CDC approved vaccines for children 11 and younger. We had a sample of n = 176 mothers (Mchildage = 71.63 months, 52% White) from California fill out an online survey during February-April 2021. Our results suggest that perceived COVID-19 threat predicts mothers' intention to vaccinate their children (b = 0.370, p < 0.001), controlling for mothers' age, socioeconomic status, race, and child age. Child age (b = 0.027, p = 0.008), SES (b = 0.396, p = 0.018), and child previous flu shot (b = 0.725, p < 0.001) also positively predicted mothers' intention to vaccinate their children. Results are discussed in light of prior research on maternal vaccine intentions and hesitancy.

Negative emodiversity is associated with emotional eating in adolescents: An examination of emotion dynamics in daily life.

INTRODUCTION: Emotional eating is a mental health concern, common in adolescents, that develops as a result of their tendency to use high-energy food to regulate their fluctuating emotions. Due to their highly fluctuating emotional life, adolescents tend to have unique within-person profiles of emotional experiences that change across moments and days, often lost in global assessments of emotions. Hence, it is imperative to examine individual differences in dynamics of emotions, as experienced in daily life, in relation to emotional eating in adolescents. METHODS: In an Ecological Momentary Assessment study, we examined individual differences in three within-person dynamic characteristics (baseline levels, intraindividual variability, and emodiversity) of emotions in 158 dominantly Hispanic adolescents in the United States, aged 14-17 years old, predicting trait-level emotional eating. RESULTS: Results indicated that higher negative emodiversity, baselines, and variability in stress were predictive of emotional eating in adolescents. When all considered together, negative emodiversity (i.e., variety of the types of negative emotions experienced in one's daily life) remained the only significant predictor of emotional eating. CONCLUSIONS: This study affirms the importance of diversity in emotional experiences in relation to emotional eating, particularly in daily contexts of adolescents' lives. Additionally, the study emphasizes the importance of distinguishing between diversity (i.e., variety in types) in positive versus negative emotional experiences with regard to emotional eating. By taking into account the ecological validity of adolescents' daily lives and individual differences in dynamical changes in emotions, we are taking a step forward by shedding light on how the dynamics of negative emotions-in terms of within-person baselines, variability, and diversity-might be related to general levels of emotional eating in adolescents.

Changes in Attachment to Parents and Peers and Relations With Mental Health During the COVID-19 Pandemic.

Using a longitudinal design, we examined changes in parent and peer attachment among college students, and their predictive and protective roles in relation to mental health problems during the COVID-19 pandemic. College students (N = 106) rated their parent and peer attachment, and self-reported anxiety, loneliness, and depressive symptoms 1 year before and during the pandemic. Participants also rated the impact of COVID-19 related stressors (CRS). Results demonstrate significant increases in loneliness and depression and a decrease in peer attachment security during the pandemic. Increases in peer attachment security were negatively correlated with loneliness during the pandemic. Parent attachment buffered the relationship between the impact of CRS and mental health problems during the pandemic. Guided by the integrated framework from attachment theory and life course theory, the current study discussed findings and practices regarding the important role of attachment for college students and their adjustment to the pandemic.

Cost of resilience: Childhood poverty, mental health, and chronic physiological stress.

Childhood poverty is associated with elevated internalizing symptoms. Nevertheless, some children exposed to poverty evince remarkable resilience, demonstrating lower than expected levels of psychological distress. However, recent work suggests that coping with adversity can lead to undesirable physical health consequences. Specifically, successful adaptation in the context of early adversity, including socioeconomic disadvantage, appears to be associated with elevated chronic physiological stress and ill health. The current study adds to this emerging literature by examining in a longitudinal context whether low levels of internalizing symptoms in the face of childhood poverty is accompanied by elevated chronic physiological stress (allostatic load) during childhood, as well as over time from childhood to adulthood. Results (n = 341; M=9.2 years, 49 % female; 94 % Caucasian) show that childhood poverty was prospectively associated with higher allostatic load during adolescence, controlling for baseline allostatic load. Furthermore, greater duration of childhood poverty led to steeper, more elevated allostatic load trajectories from childhood to adulthood, for youth with lower levels of internalizing symptoms. Efforts to manage adverse sequelae of early adversity likely yield a complex array of benefits and costs.

Resilience and Family Socialization Processes in Ethnic Minority Youth: Illuminating the Achievement-Health Paradox.

Youth in marginalized communities who "strive" to rise above adversity, including systemic racism and poverty, are considered "resilient." African-American, Latinx, and Asian-American youth often achieve admirable academic success despite limited social capital and high early life stress by adopting a "striving persistent behavioral style" (SPBS). SPBS may be supported by family socialization processes that facilitate reliance on self-regulation processes. Unfortunately, a young person's resilience in one domain (i.e., academic) can come at a cost in other domains, including physical and mental health morbidities that are under-identified and under-treated. Indeed, research suggests a link between SPBS in the face of adversity and later health morbidities among ethnic minority youth. Herein, we describe SPBS as an adaptation to minority stress that not only promotes social mobility but may also stoke physical and mental health disparities. We review how family processes related to academic, emotional, and ethnic-racial socialization can facilitate the striving persistent behavioral style. We emphasize the double bind that ethnic minority families are caught in and discuss directions for future research and clinical implications for individual and family-level interventions. While needed, we argue that individual and family-level interventions represent a near-term work around. Solutions and factors that shape the need for SPBS and its cost must be addressed structurally.

A mother's touch: Preschool-aged children are regulated by positive maternal touch.

Positive maternal touch plays an important role in the development of children's physiological regulation and cognitive development in infancy, as well as the development of sociality in early childhood. However, few studies have looked beyond infancy to consider the possible continuing impact of positive maternal touch on child stress reactivity during early childhood. A diverse community sample of mothers (N = 114, Mage  = 33.52 years, SD = 5.33) and their preschool-aged children (Mage  = 41.68 months, SD = 4.67; 49.1% female) participated in the study. Basic demographics were reported by mothers. We coded maternal touch behaviors during an emotionally charged laboratory conversation task and assessed children's physiological reactivity to stressful laboratory tasks with salivary cortisol. Results reveal a significant negative association between positive maternal touch and child salivary cortisol reactivity. In addition, family income, adjusted for family size, and child sex were significantly associated with child cortisol stress reactivity. Findings are discussed in terms of persistent downregulating effects of positive maternal touch on child stress reactivity, as well as possible links of stress reactivity with family income, a proxy for economic stress, and child sex.

Stressed out and fed up: The effect of stress on maternal feeding behaviors and the moderating role of executive function.

Stress is associated with a range of unhealthy eating habits, yet few studies have examined how stress may influence the intergenerational transmission of eating habits from parents to their children. Specifically, there is a lack of data regarding the role of stress on feeding practices. Moreover, most work investigating the associations between parental stress and their feeding behaviors has been correlational, limiting our understanding of causality. In the current study, we used an experimental design, induced high and low stress in mothers using a standard laboratory stressor, and observed mother-child interactions during a snack break. We also examined the potential role of maternal executive functioning (EF) for buffering the effects of stress on maternal feeding behaviors. Levels of maternal stress were manipulated with the Trier Social Stress Task (TSST) in a community sample (N = 80 dyads, Child Mage = 41.89 months, female = 43). We measured maternal EF with a series of computerized tasks. Maternal feeding behaviors were coded for controlling behaviors, which included pressuring and restricting behaviors. Results indicate a main effect of stress on controlling feeding behaviors, such that mothers in the high-stress condition exhibited higher levels of controlling behaviors. The effect of stress on controlling feeding behaviors was ameliorated among mothers with higher levels of EF after controlling for child age and income. Results provide causal evidence for the role of stress on feeding behaviors and suggest EF as a factor to be considered in the treatment and prevention of diet-related illnesses.

Loneliness and cravings for sugar-sweetened beverages among adolescents.

PURPOSE: The consumption of sugar-sweetened beverages (SSBs) is associated with weight gain in both children and adults. In addition to environmental factors, such as food availability, psychological variables, including mood states, also impact intake. In the current study, we focus on momentary associations between feelings of loneliness and craving for SSBs among adolescents and explore the moderating role of family functioning. Loneliness has been associated with a wide range of health outcomes, but to date, few studies have examined its association with cravings for SSBs. METHODS: Using an ecological-momentary assessment design, data were collected on 158 (males = 68, mean age = 15.13 ± 2.27 years) participants. Multilevel mixed-effects models were used to examine the relations between the main and interactive effects of loneliness and family functioning on cravings for SSBs, independent of other negative emotions. RESULTS: Results suggest that loneliness in adolescents was associated with a small increase in craving for SSBs. Importantly, the relationship held after controlling for negative emotions, suggesting the unique role of loneliness. However, positive family functioning did not mitigate the relations between loneliness and craving for SSBs. CONCLUSIONS: Loneliness uniquely contributes to cravings for SSBs. At the same time, family functioning did not buffer the influence of loneliness on cravings for SSBs among adolescents.

The roles of life stress and preventive health behaviors on parent mental health during the COVID-19 pandemic.

The COVID-19 pandemic has disrupted millions of lives, with life stress and daily hassles having a potential impact on parent mental health. This study examined whether preventive health behaviors (e.g. social distancing, mask wearing) and social support relate to parent mental health. In a cross-sectional analysis of parents (N = 176, May-September 2020), life events and daily hassles were positively associated with depressive and anxiety symptoms. Preventive health behaviors moderated the association between daily hassles and depressive symptoms. Preventive health behaviors may protect those with high levels of daily hassles from moderate levels of depression.

Allostatic load: Developmental and conceptual considerations in a multi-system physiological indicator of chronic stress exposure.

Developmental researchers studying how stress affects health have often focused on specific, individual, physiological parameters such as cortisol. Yet, recent theories of stress biology emphasize that the stress response is multi-faceted and engages distinct yet interconnected physiological systems, including metabolic, immune, and cardiovascular systems that respond to one another. Moreover, advocates of a systems approach also argue that the confluence of changes across several physiological systems presents a health risk, even when one indicator alone is not predictive of health outcomes. Allostatic load is one potential multi-system indicator of stress, capturing the cumulative, physiological burden of chronic stress exposure on the body. At the same time, studying allostatic load during early development raises several issues, including how allostatic load is operationalized, the clinical importance of commonly used biomarkers during distinct periods of development, and the fundamental role of timing. In this review paper, we discuss the potential of allostatic load in the context of studies of stress in developmental science, review developmental studies that have assessed allostatic load, and articulate critical conceptual questions regarding the study of allostatic load during the childhood years.

The physical health costs of positive adaptation to childhood adversity.

Theories of allostatic load suggest that recurrent adaptive adjustments in contexts of adversity may have a negative impact on physical well-being. To test this hypothesis, this study evaluated 6-year-old children's ego-resilience and physical abuse experiences on behavior problems and physical illness at the age of 8 years. A significant interaction between ego-resilience and physical abuse exposure indicated that, although ego-resilience buffered physically abused children from internalizing problems, it also predicted more physical illness in that group. Findings contribute to the growing body of evidence suggesting that efforts to mobilize an adaptive response in contexts of adversity may exact a cost on physical well-being.

Changes in Depressive Symptoms, Physical Symptoms, and Sleep-Wake Problems from before to during the COVID-19 Pandemic among Emerging Adults: Inequalities by Gender, Socioeconomic Position, and Race.

The impact of the COVID-19 pandemic on emerging adults is of global concern. We examine changes in depressive symptoms, physical symptoms, and sleep-wake problems from before to during the pandemic among college students, and examine inequalities by gender, socioeconomic status (SES), and race (N=263, 52% Black, 48% White, 53% female). As compared to pre-pandemic levels, increases were evident in depressive symptoms, physical symptoms, and sleep problems. Females had greater increases than males in depressive symptoms, sleep problems, and physical symptoms. Students from disadvantaged SES backgrounds had greater increases in physical symptoms. Among White students, those from disadvantaged backgrounds also had greater increases in sleep problems. Lastly, daytime sleepiness increased more among Black male than White male students. Overall, findings suggest notable shifts in sleep and health during the early phase of the pandemic among emerging adults, and that attention to inequality by gender, SES, and race is warranted.
