The effect of sleep deprivation and restriction on mood, emotion, and emotion regulation: three meta-analyses in one
2021
Abstract
Study Objectives
New theory and measurement approaches have facilitated nuanced investigation of how sleep loss impacts dimensions of affective functioning. To provide a quantitative summary of this literature, three conceptually related meta-analyses examined the effect of sleep restriction and sleep deprivation on mood, emotion, and emotion regulation across the lifespan (i.e. from early childhood to late adulthood).
Methods
A total of 241 effect sizes from 64 studies were selected for inclusion, and multilevel meta-analytic techniques were used when applicable.
Results
There was a moderate, positive effect of sleep loss on negative mood (g = 0.45), which was stronger for studies with younger samples, as well as a large, negative effect of sleep loss on positive mood (g = −0.94). For negative mood only, studies that used total sleep deprivation had larger effect sizes than studies that restricted sleep. After correcting for publication bias, a modest but significant negative effect for sleep loss on emotion (g = −0.11) was found; the valence of emotional stimuli did not change the direction of this effect, and type of sleep manipulation was also not a significant moderator. Finally, sleep restriction had a small, negative effect on adaptive emotion regulation (g = −0.32), but no significant impact on maladaptive emotion regulation (g = 0.14); all studies on adaptive emotion regulation were conducted with youth samples.
Conclusions
Sleep loss compromises optimal affective functioning, though the magnitude of effects varies across components. Findings underscore the importance of sleep for healthy affective outcomes.

Much Ado About Missingness: A Demonstration of Full Information Maximum Likelihood Estimation to Address Missingness in Functional Magnetic Resonance Imaging Data
2021
The current paper leveraged a large multi-study functional magnetic resonance imaging (fMRI) dataset ( N = 363) and a generated missingness paradigm to demonstrate different approaches for handling missing fMRI data under a variety of conditions. The performance of full information maximum likelihood (FIML) estimation, both with and without auxiliary variables, and listwise deletion were compared under different conditions of generated missing data volumes (i.e., 20, 35, and 50%). FIML generally performed better than listwise deletion in replicating results from the full dataset, but differences were small in the absence of auxiliary variables that correlated strongly with fMRI task data. However, when an auxiliary variable created to correlate r = 0.5 with fMRI task data was included, the performance of the FIML model improved, suggesting the potential value of FIML-based approaches for missing fMRI data when a strong auxiliary variable is available. In addition to primary methodological insights, the current study also makes an important contribution to the literature on neural vulnerability factors for obesity. Specifically, results from the full data model show that greater activation in regions implicated in reward processing (caudate and putamen) in response to tastes of milkshake significantly predicted weight gain over the following year. Implications of both methodological and substantive findings are discussed.

Sleep is a key restorative process, and poor sleep is linked to disease and
mortality risk. The adolescent population requires more sleep on average than
adults but are most likely to be sleep deprived. Adolescence is a time of rapid
social upheaval and sensitivity to social stressors including discrimination.
This study uses two weeks of daily e-diary measures documenting discrimination
exposure and concurrent objective sleep indicators measured using actigraphy. We
assess associations between daily discrimination and contemporaneous sleep with
a diverse sample of adolescents. This novel study shows youth with higher
average discrimination reports have worse average sleep relative to their
counterparts. Interestingly, youth reporting daily discrimination have better
sleep the day of the report than youth who do not.

Contextualizing the Neural Vulnerabilities Model of Obesity
2023
In recent years, investigators have focused on neural vulnerability factors that increase the risk of unhealthy weight gain, which has provided a useful organizing structure for obesity neuroscience research. However, this framework, and much of the research it has informed, has given limited attention to contextual factors that may interact with key vulnerabilities to impact eating behaviors and weight gain. To fill this gap, we propose a Contextualized Neural Vulnerabilities Model of Obesity, extending the existing theory to more intentionally incorporate contextual factors that are hypothesized to interact with neural vulnerabilities in shaping eating behaviors and weight trajectories. We begin by providing an overview of the Neural Vulnerabilities Model of Obesity, and briefly review supporting evidence. Next, we suggest opportunities to add contextual considerations to the model, including incorporating environmental and developmental context, emphasizing how contextual factors may interact with neural vulnerabilities to impact eating and weight. We then synthesize earlier models and new extensions to describe a Contextualized Neural Vulnerabilities Model of Obesity with three interacting components—food reward sensitivity, top-down regulation, and environmental factors—all within a developmental framework that highlights adolescence as a key period. Finally, we propose critical research questions arising from the framework, as well as opportunities to inform novel interventions.

Racism-related stress is thought to contribute to widespread race/ethnic health inequities via negative emotion and allostatic stress process up-regulation. Although prior studies document race-related stress and health correlations, due to methodological and technical limitations, they have been unable to directly test the stress-reactivity hypothesis in situ. Guided by theories of constructed emotion and allostasis, we developed a protocol using wearable sensors and daily surveys that allowed us to operationalize and time-couple self-reported racism-related experiences, negative emotions, and an independent biosignal of emotional arousal. We used data from 100 diverse young adults at a predominantly White college campus to assess racism-related stress reactivity using electrodermal activity (EDA), a biosignal of sympathetic nervous system activity. We find that racism-related experiences predict both increased negative emotion risk and heightened EDA, consistent with the proposed allostatic model of health and disease. Specific patterns varied across race/ethnic groups. For example, discrimination and rumination were associated with negative emotion for African American students, but only interpersonal discrimination predicted increased arousal via EDA. The pattern of results was more general for Latinx students, for whom interpersonal discrimination, vicarious racism exposure, and rumination significantly modulated arousal. As with Latinx students, African students were particularly responsive to vicarious racism while 1.5 generation Black students were generally not responsive to racism-related experiences. Overall, these findings provide support for allostasis-based theories of mental and physical health via a naturalistic assessment of the emotional and sympathetic nervous system responding to real-life social experiences.

Objective The goal of the current study was to test prospective direct and indirect associations between preschool executive control (EC), parental affective quality and harsh discipline, and adolescent substance use (e‐cigarettes, cannabis, and alcohol) while accounting for participants' age, sex, family history of substance use, and family socioeconomic status. Method Participants were 313 youth (49% boys; 70.9% European American) and their parents who participated in a longitudinal cohort‐sequential study on the development of EC in preschool and its associations with subsequent health outcomes. Substance use initiation and frequency (e‐cigarettes, cannabis, and alcohol) were obtained via phone surveys from youth who participated in adolescent assessments. Parental affective quality and harsh discipline were obtained from parental questionnaires in adolescence. Results The direct effects from preschool EC on adolescent substance use were statistically nonsignificant for e‐cigarettes, cannabis, and alcohol. Mediation analyses revealed a statistically significant indirect effect from preschool EC to adolescent use of e‐cigarettes through harsh discipline (b = −0.07 [95% CI = −0.18; −0.01]; β = −0.04). The associations between preschool EC and any of the substance use outcomes in adolescence through parental affective quality were nonsignificant. Conclusions This study fills significant gaps in the emerging literature on longitudinal contributions of child characteristics to parenting behaviors, suggesting that early EC deficiencies may elicit more harsh discipline during adolescence, ultimately leading to higher adolescent engagement in e‐cigarette use.

There is a critical need for research examining how neural vulnerabilities associated with obesity, including lower executive control, interact with family factors to impact weight trajectories across adolescence. Utilizing a longitudinal design, the present study investigated caregivers’ emotion socialization practices as a moderator of the association between preschool executive control and adolescent body mass index (BMI) trajectories. Participants were 229 youth (Mage = 5.24, SD = 0.03; 47.2% assigned female at birth; 73.8% White, 3.9% Black, 0.4% Asian American, 21.8% multiracial; 12.7% Hispanic) enrolled in a longitudinal study. At preschool-age, participants completed performance-based executive control tasks, and their caregivers reported on their typical emotion-related socialization behaviors (i.e., supportive and nonsupportive responses to children’s negative emotions). Participants returned for annual laboratory visits at ages 14 through 17, during which their height and weight were measured to calculate BMI. Although neither preschool executive control nor caregiver emotion-related socialization behaviors were directly associated with BMI growth in adolescence, supportive responses moderated the association between executive control and BMI trajectories. The expected negative association between lower preschool executive control and greater BMI growth was present at below average levels of supportive responses, suggesting that external regulation afforded by supportive responses might reduce risk for adolescent overweight and obesity among children with lower internal self-regulatory resources during preschool. Findings highlight the importance of efforts to bolster executive control early in development and targeted interventions to promote effective caregiver emotion socialization (i.e., more supportive responses) for youth with lower internal self-regulatory abilities to mitigate risk for overweight and obesity and promote health across childhood and adolescence.

Identifying childhood cognitive processes that predict adolescent problem behaviors can help guide understanding and prevention of these behaviors. In a community sample of 313 youth recruited in a small Midwestern city between 2006 and 2012 (49% male, 64% European American), executive control and foundational cognitive abilities were assessed at age 5 in a lab setting with performance-based measures. In adolescence, youth provided self-report of problem behaviors in surveys administered annually between ages 14 and 16. Executive control was negatively associated with externalizing behavior problems and adolescents getting in trouble at school, accounting for foundational cognitive abilities and family background covariates. Executive control had negative, but nonsignificant, associations with internalizing problems and substance use initiation. The findings point to deficits in executive control as a childhood risk factor for later problems and a potential target for preventive interventions.

The goal of this study was to examine reciprocal associations between cognitive flexibility and externalizing and internalizing behavior problems longitudinally using data on four occasions from kindergarten through first grade and test for potential gender differences in these associations. The Dimensional Change Card Sort task was used to assess children’s cognitive flexibility as a measure of executive function. Participants were 12,462 kindergarteners (49% female) from the Early Childhood Longitudinal Study (ECLS-K: 2011). Results from multivariate latent curve models with structured residuals revealed that children’s cognitive flexibility at the beginning of kindergarten was not associated with their growth in either externalizing (r = -0.01, p = .174), or internalizing (r = -0.03, p = .403) problems between kindergarten and the end of first grade. However, after controlling for individual differences in growth, cognitive flexibility at each assessment directly contributed to subsequent lower levels of internalizing (but not externalizing) behavior problems at the next assessment (b = -0.004, p = 0.013; β = -0.03), suggesting that children who are more flexible in switching from one activity to another may be less prone to developing internalizing problems. At kindergarten entry boys had lower levels of cognitive flexibility (b = -0.31, p < .001, β = -.12) and higher levels of externalizing (b = 0.25, p < .001, β = .23), and internalizing problems(b = 0.04, p = 001, β = .05) compared to girls, but did not differ from girls in their rates of change in cognitive flexibility and externalizing or internalizing behavior problems.

Background
Accurate parental perceptions of their children’s underweight status are needed to prevent overlooking potential disordered eating patterns or health conditions affecting growth.
Purpose
The aim of this study is to determine overall proportion of parents who misperceive children’s underweight status and correlates of such misperceptions.
Methods
Original studies published to January 2013 were chosen through a literature search in established databases. Studies included assessed parental perceptions of their children’s underweight and then compared perceptions to recognized standards for defining underweight based on anthropometric measures. Random- and mixed-effects models were used.
Results
Thirty-seven articles (representing 39 studies;
N
= 4,039) were included. Pooled effect sizes indicated that 46.58 % (95 % CI 40.90–52.35 %) of parents misperceive their children’s underweight status, though the extent of misperceptions depended on a number of moderators.
Conclusions
Nearly half of parents perceive their underweight children as weighing more than they actually do. Health care professionals are well positioned to take steps to remedy misperceptions and encourage healthy behaviors.
