Early-life nutritional supplementation protects against home environmental risks in Ghanaian children's social-emotional development.

Introduction: This study examines how an early-life small-quantity lipid-based nutrient supplement (LNS) interacts with the home environment to influence Ghanaian children's social-emotional functioning at preschool age.

Method: In a randomized controlled trial, 1,320 Ghanaian women received either daily LNS, multiple micronutrients (MMN) or iron and folic acid (IFA) during pregnancy through 6 months postpartum. Infants in the LNS group received the daily supplement from 6 to 18 months.

Economic, socio-emotional, and food security conditions during COVID-19 pandemic among caregivers of young adolescents aged 10-12 yrs in a semi-urban setting in Ghana.

Background Few studies have described the consequences of the COVID - 19 pandemic among caregivers of young adolescents in sub-Saharan Africa. We aimed to explore the consequences of COVID-19 on economic, socio-emotional, and household food security conditions among caregivers of young adolescents in a semi-urban setting in the Eastern Region of Ghana. Methods In this cross-sectional study, caregivers of young adolescents aged 10-12yrs in the Somanya-Kpong area were enrolled.

Parasympathetic reactivity to recalled emotional experiences and adolescent prosociality.

Prosociality, which refers to dispositions to allocate one's attention and energy to the needs of others, is indicative of social proficiency and adaptive functioning in adolescence. Greater abilities for self-regulation in adolescence are widely considered to foster prosociality (Hastings et al., 2023; Hodge et al.

Lifetime heterosexist victimization and diurnal cortisol predict depression trajectories among sexual and gender minority emerging adults.

Heterosexist victimization constitutes a severe source of social stress with enduring effects on mental health and the adrenocortical functioning of lesbian, gay, bisexual, transgender, and queer (LGTBQ) emerging adults. However, it is unknown what roles lower or higher diurnal cortisol at waking (cortisol intercepts) and less variable fluctuations ("flatter" slopes) play in the links between heterosexist victimization and depressive symptoms. In accordance with diathesis-stress, allostatic load, and biological embedding perspectives, we examined whether cortisol intercepts and slopes moderated or mediated the predictive associations of heterosexist victimization with depressive symptoms over 24-months.

Maternal Emotion Regulation and Parenting: A Physiological Perspective.

The psychological capacity for emotion regulation (ER) facilitates sensitive caregiving and fosters positive child outcomes. Parasympathetic regulation, indexed by respiratory sinus arrhythmia (RSA), is an important physiological component of ER. While growing evidence supports the link between parents' physiological ER and parenting behaviors, few studies distinguish parents' global ER capacity from ER in parenting-specific contexts, which can provide important insights for intervention.

Impact of fidget devices on anxiety and physiological responses in adults with ADHD.

Background: Fidgeting devices are popular for managing ADHD, but their effectiveness remains unclear. This study investigated whether fidgeting modulates self-regulation in adults with ADHD during stress, exploring intrinsic versus extrinsic fidgeting with a fidget ball. We hypothesized that individuals with a fidget ball would demonstrate improved self-regulation under stress, reflected by higher heart rate variability (HRV) and lower anxiety levels.

Impact of Small-Quantity Lipid-Based Nutrient Supplements on Pubertal Status of 9-13-Year Olds: A Follow-Up Study of the iLiNS-DYAD-Ghana Trial.

Background: Early and delayed puberty are both associated with adverse health and psychosocial outcomes.

Objectives: We assessed the impact of provision of small-quantity lipid-based nutrient supplement (SQ-LNS) to mothers during pregnancy and 6 mo postpartum and to their children aged 6-18 mo, on pubertal status.

Methods: This study was a follow-up to a partially double-blind randomized controlled trial.

Assessing Children's Autonomic Nervous System Activity During Structured Tasks: A Feasibility and Reliability Study in Ghana.

The significance of physiological regulation in relation to behavioral and emotional regulation is well documented, but primarily in economically advantaged contexts. Few studies have been conducted in low- and middle-income countries. We investigated the feasibility and reliability of measuring autonomic nervous system (ANS) activity and behavior during challenge tasks in 30 children aged 8-10 years in Ghana during two visits, 1 week apart.

Brain network connectivity during peer evaluation in adolescent females: Associations with age, pubertal hormones, timing, and status.

Despite copious data linking brain function with changes to social behavior and mental health, little is known about how puberty relates to brain functioning. We investigated the specificity of brain network connectivity associations with pubertal indices and age to inform neurodevelopmental models of adolescence. We examined how brain network connectivity during a peer evaluation fMRI task related to pubertal hormones (dehydroepiandrosterone and testosterone), pubertal timing and status, and age.

Sustained effects of small-quantity lipid-based nutrient supplements provided during the first 1000 days on child growth at 9-11 y in a randomized controlled trial in Ghana.

Background: There is limited research on whether nutritional supplementation in the first 1000 d affects long-term child outcomes. We previously demonstrated that pre- and postnatal small-quantity lipid-based nutrient supplements (SQ-LNS) increased birth weight and child length at 18 mo of age in Ghana.

Objectives: We aimed to investigate the effect of pre- and postnatal SQ-LNS on child growth and blood pressure at 9-11 y.

Specialized and versatile antisocial behavioral profiles in preschoolers: Associations with persistent behavioral problems.

This study investigated specialized and versatile antisocial patterns in preschoolers and examined the link between these patterns and the risk of developing chronic antisocial behaviors throughout childhood. A total of 556 children (50.6% boys, 88% White) participated in this three-wave longitudinal study at 3-5, 6-8, and 10-12 years old.

Cognitive Reappraisal and Need to Belong Predict Prosociality in Mexican-Origin Adolescents.

This two-year longitudinal study examined Mexican-origin adolescents' need to belong and cognitive reappraisal as predictors of multiple forms of prosocial behavior (i.e., general, emotional, and public prosocial behaviors).

Threat exposure moderates associations between neural and physiological indices of emotion reactivity in adolescent females.

Early life adversity (ELA) characterized by threat (e.g., abuse, witnessing violence) impacts neural and physiologic systems involved in emotion reactivity; however, research on how threat exposure impacts the interplay between these systems is limited.

Prenatal and postnatal small-quantity lipid-based nutrient supplements and children's social-emotional difficulties at ages 9-11 y in Ghana: follow-up of a randomized controlled trial.

Background: Provision of small-quantity lipid-based nutrient supplements (SQ-LNSs) during early life improves growth and development. In the International Lipid-Based Nutrient Supplements DYAD-Ghana trial, prenatal and postnatal SQ-LNS reduced social-emotional difficulties at age 5 y, with greater effects among children in less-enriched home environments.

Objectives: We aimed to investigate the effect of prenatal and postnatal SQ-LNS on children's social-emotional problems at age 9-11 y.
