Associations among prenatal stress, socioeconomic status, and infant epigenetic aging.

This pre-registered study investigated the associations between prenatal stress and socioeconomic disadvantage with epigenetic aging in one-month-old infants. We hypothesized that exposure to greater maternal perceived stress, maternal physiological stress, and family socioeconomic disadvantage would be associated with accelerated epigenetic aging among infants. A socioeconomically and racially diverse sample of mothers were recruited during their last 5 weeks of pregnancy, when they completed surveys on their family income, education, and perceived stress levels, and provided a hair sample to index hair cortisol concentration.

Associations Between Prenatal Maternal Stress and Infant Resting Brain Activity: A Preregistered Investigation.

Mounting evidence suggests that maternal stress is associated with infants' brain activity, but the role of maternal stress during pregnancy is not yet understood. The present preregistered investigation examines associations between prenatal maternal stress (physiological and perceived) and infant brain activity at 1 month of age. A sample of diverse mother-infant dyads (N = 160) participated (55% female; 39% White).

Men of Color Health Awareness intervention: changes in adrenocortical activity assessed using fingernail cortisol.

Introduction: A randomized controlled trial (#NCT03745703) assessed the efficacy of a tailored stress reduction intervention (Men of Color Health Awareness; MOCHA) aimed at improving the health of middle-aged African-American men. The present paper presents an exploratory study of whether the intervention affected chronic output of the stress hormone cortisol using the novel approach of measuring cortisol accumulation in fingernail samples. Each fingernail sample was hypothesized to contain cortisol deposited over approximately a 3-month period before collection.

MOCHA Moving Forward: findings and lessons learned from implementing a community-based chronic disease prevention study with middle-aged black men.

Objectives: Black men in the U.S. experience disproportionately high rates of diabetes, cardiovascular disease, and prostate cancer - conditions closely linked to chronic stressors such as racial discrimination, economic precarity, and gender role strain.

No Effect of Infant Nursery Rearing on Laboratory Rhesus Monkey Dams' Social Behavior or Long-Term Cortisol Profiles.

While the behavioral and physiological impacts of nursery rearing in laboratory-housed infant monkeys have been well characterized, to date no studies have examined the impact on nonhuman primate dams of their infants being removed for rearing in the nursery. Despite the lack of evidence on the topic, anti-animal research groups often cite mother-infant separation and infant nursery rearing (NR) as a welfare concern for laboratory monkey mothers. As such, important policy decisions regarding research activities may result without adequate evidence.

A single-arm, open-label pilot study of neuroimaging, behavioral, and peripheral inflammatory correlates of mindfulness-based stress reduction in multiple sclerosis.

Multiple sclerosis (MS) is a chronic neurological disease frequently associated with significant fatigue, anxiety, depression, and stress. These symptoms are difficult to treat, and prominently contribute to the decreases in quality of life observed with MS. The underlying mechanisms of these "silent" symptoms are not well understood and include not just the psychological responses to a chronic disease, but also biological contributions from bidirectional psycho-neuro-immune (dys)regulation of systemic inflammatory biology.

Prenatal family income, but not parental education, is associated with resting brain activity in 1-month-old infants.

Childhood socioeconomic disadvantage is associated with disparities in development and health, possibly through adaptations in children's brain function. However, it is not clear how early in development such neural adaptations might emerge. This study examined whether prenatal family socioeconomic status, operationalized as family income and average years of parental education, prospectively predicts individual differences in infant resting electroencephalography (EEG; theta, alpha, beta, and gamma power) at approximately 1 month of age (N = 160).

Alterations in adolescent brain serotonin (5HT), 5HT, and dopamine (D) receptor systems in a nonhuman primate model of early life adversity.

Stress affects brain serotonin (5HT) and dopamine (DA) function, and the effectiveness of 5HT and DA to regulate stress and emotional responses. However, our understanding of the long-term impact of early life adversity (ELA) on primate brain monoaminergic systems during adolescence is scarce and inconsistent. Filling this gap in the literature is critical, given that the emergence of psychopathology during adolescence has been related to deficits in these systems.

Refugee health and physiological profiles in transitional settlements in Serbia and Kenya: Comparative evidence for effects of gender and social support.

When armed conflict compels people to flee from their homelands, they embark on protracted journeys during which they experience wide ranging physical, social, and psychological challenges. Few studies have focused on refugee psychosocial and physiological profiles during the transitional phase of forced migration that often involves temporary sheltering. Transient refugees' experiences can vary substantially based on local socio-ecological conditions in temporary settlements, including the length of stay, living conditions, as well as the availability and accessibility of physical and social resources.

Amniotic fluid cortisol predicts neonatal and infant development in non-stressed rhesus monkeys: Implications for prenatal stress.

Prenatal stress adversely affects offspring development, with fetal cortisol (CORT) exposure being a primary hypothesized mechanism for stress-induced developmental deficits. Fetal CORT exposure can be assessed via measurements in amniotic fluid. However, in humans, amniocentesis is typically only performed for clinical reasons such as karyotyping; thus, amniotic fluid CORT cannot be obtained from a random sample.

Associations between maternal stress and infant resting brain activity among families residing in poverty in the U.S.

Growing evidence suggests that maternal experiences of stress shape children's functional brain activity in the first years of life. Individuals living in poverty are more likely to experience stress from a variety of sources. However, it is unclear how stress is related to resting brain activity among children born into poverty.

Are hair cortisol levels dependent on hair growth rate? A pilot study in rhesus macaques.

Research incorporating the analysis of glucocorticoids, specifically cortisol, in hair samples has exploded over the past 10-15 years, yet factors contributing to the accumulation of cortisol in hair are not yet fully characterized. In particular, it is not clear whether cortisol accumulation in hair is dependent on hair growth rate, a possibility raised by prior rodent studies reporting glucocorticoid-mediated inhibition of hair growth. Using rhesus macaque monkeys (Macaca mulatta), an extensively studied nonhuman primate species, the present pilot study evaluated the hypothesis that hair cortisol accumulation is inversely related to hair growth rate (i.

Co-Rooming Accounts for Socioeconomic Disparities in Infant Sleep Quality among Families Living in Urban Environments.

Poor infant sleep quality is associated with negative maternal and infant health outcomes. This study measures socioeconomic disparities in infant sleep quality, and assesses whether child sleep location and maternal stress mediate associations between socioeconomic status (SES) and infant sleep quality. The study includes 86 socioeconomically diverse, mother-infant dyads living in an urban area with infants aged 6-12 months.

Longitudinal Examination of Hair Cortisol Concentrations and Weight Changes in Preschool-Aged Children of Latino Farmworkers.

Hair cortisol concentrations may serve as a measure of biologically embedded stress. While the cross-sectional association between hair cortisol and obesity in children has been examined, the data examining this relationship over time are limited. We examined hair cortisol and anthropometrics in 40 children with obesity from Latino families enrolled in a Head Start program serving farmworkers.

Peer-led family-centred problem management plus for immigrants (PMP-I) for mental health promotion among immigrants in USA: protocol for a pilot, randomised controlled feasibility trial.

Introduction: Research is needed to investigate preventive strategies to reduce mental health burden and assess effective implementation among immigrants. Problem management plus (PMP) is a low-intensity multicomponent psychological intervention developed by the World Health Organization (WHO) that trained laypeople can deliver. PMP has been adapted as a prevention intervention and developed as PMP for immigrants (PMP-I), including psychoeducation, problem-solving, behavioural activations and mind-body exercise, to address immigrants' multiple stressors.

Social Fear in US Infants: The Roles of Hair and Salivary Cortisol.

Elevated social fear in infancy poses risk for later social maladjustment and psychopathology. Hair cortisol concentration (HCC), an index of cumulative cortisol exposure, and diurnal salivary cortisol slope, a biomarker of acute stress regulation, have been associated with social fear behaviors in childhood; however, no research has addressed their relations in infancy. Elucidating potential biomarkers of infant social fear behaviors, as well as environmental factors associated with these biomarkers, may grant insights into the ontogeny of fear behaviors that increase risk for internalizing and externalizing psychopathologies later in life.

Transient refugees' social support, mental health, and physiological markers: Evidence from Serbian asylum centers.

Objectives: Refugees seeking safety across international borders are often exposed to a wide breadth of psychosocially stressful experiences that may fracture existing sources of social support and impair the generation of new social relationships, with implications for their long-term health and resilience. Using data from recently settled refugees in two asylum centers in Serbia, we examined the associations between social support, mental health, and physiological markers.

Methods: In this mixed-method study of refugees (age 18-50 years, n = 76), we collected key socio-demographic information and conducted semi-structured interviews about refugees' journey and stay in Serbia, trauma/loss, and their sources of social support.
