Parenting and Salience Network Connectivity Among African Americans: A Protective Pathway for Health-Risk Behaviors

Supportive parenting during childhood has been associated with many positive developmental outcomes for offspring in adulthood, including fewer health-risk behaviors. Little is known about the neural mechanisms underlying these associations. The present study followed rural African Americans (n = 91, 52% female) from late childhood (ages 11-13) to emerging adulthood (age 25). Parent-child communication was assessed at ages 11, 12, and 13. Functional magnetic resonance imaging was used at age 25 to measure resting state functional connectivity (rsFC) of the ...

A systematic review of dropout from organized sport among children and youth

Leisure constraints theory was used as a framework to systematically review factors associated with dropout of organized sport among children and adolescents. Keyword searches for the population, context and construct of interest (i.e. dropout) identified articles from the entire contents of the following databases: Academic Search Complete, ERIC, MEDLINE, PsycINFO and SPORTDiscus. The initial search yielded 557 studies, and 43 met the selection criteria. Most studies focused solely on adolescents, and 89% of participants were male. Most studies were cross-sectional ...

Early-Life Adversity and Physical and Emotional Health Across the Lifespan: A Neuroimmune Network Hypothesis

Children who experience chronic stressors are vulnerable to emotional and physical health problems across the lifespan. This phenomenon raises questions for scientists and clinicians alike. How does adversity get under the skin of the developing child? Through what mechanisms does it confer vulnerability to a heterogeneous set of mental and physical illnesses? And how does it instantiate risk across different life stages, engendering vulnerability to conditions that develop shortly after stressor exposure—like depression—and conditions that manifest decades later, like heart ...

16 Positive Youth Development and Relational-Developmental-Systems

Interests in the strengths of youth, the plasticity of human development, and the concept of resilience coalesced in the 1990s to foster the development of the concept of positive youth development (PYD). As discussed by Hamilton (1999), the concept of PYD was understood in at least three interrelated but nevertheless different ways: (1) as a developmental process; (2) as a philosophy or approach to youth programming; and (3) as instances of youth programs and organizations focused on fostering the healthy ...

Parenting stress and child behavior problems within families of children with developmental disabilities: Transactional relations across 15 years

Parents of children with developmental disabilities (DD) are at increased risk of experiencing psychological stress compared to other parents. Children’s high levels of internalizing and externalizing problems have been found to contribute to this elevated level of stress. Few studies have considered the reverse direction of effects, however, in families where a child has a DD. The present study investigated transactional relations between child behavior problems and maternal stress within 176 families raising a child with early diagnosed DD. There ...

A heavy burden on young minds: the global burden of mental and substance use disorders in children and youth

Mental and substance use disorders are common and often persistent, with many emerging in early life. Compared to adult mental and substance use disorders, the global burden attributable to these disorders in children and youth has received relatively little attention.

Data from the Global Burden of Disease Study 2010 was used to investigate the burden of mental and substance disorders in children and youth aged 0–24 years. Burden was estimated in terms of disability-adjusted life years (DALYs), derived from the sum ...

Supporting Public Health Priorities: Recommendations for Physical Education and Physical Activity Promotion in Schools

Physical activity (PA) provides numerous physiological and psychosocial benefits. However, lifestyle changes, including reduced PA opportunities in multiple settings, have resulted in an escalation of overweight and obesity and related health problems. Poor physical and mental health, including metabolic and cardiovascular problems is seen in progressively younger ages, and the systematic decline in school PA has contributed to this trend. Of note, the crowded school curriculum with an intense focus on academic achievement, lack of school leadership support, funding and ...

Adverse Childhood Experiences and Mental Health, Chronic Medical Conditions, and Development in Young Children

This cross-sectional study used a nationally representative sample of children investigated by child welfare (National Survey of Child and Adolescent Well-Being II) from 2008 to 2009. Our analysis included caregiver interviews and caseworker reports about children aged 18 to 71 months who were not in out-of-home care (n = 912). We examined the associations between ACEs and mental health (measured by the Child Behavior Checklist [CBCL]), reported chronic medical conditions, and social development (measured by the Vineland Socialization Scale) in ...

Contribution of snacks to dietary intakes of young children in the United States

Nutritional quality of children’s diets is a public health priority in the fight against childhood obesity and chronic diseases. The main purpose of this study was to determine contribution of snacks to energy and nutrient intakes and to identify leading snack food sources of energy, total fat, and added sugars amongst young children in the United States. Using the 2005–2012 NHANES data, dietary intakes of 2- to 5-year-old children were analysed from a parent-reported 24-hour dietary recall (n = 3,429). Snacking occasions ...

Effect of a Text Messaging Intervention on Influenza Vaccination in an Urban, Low-Income Pediatric and Adolescent Population

Influenza infection results in substantial costs, morbidity, and mortality. Vaccination against influenza is particularly important in children and adolescents who are a significant source of transmission to other high-risk populations, yet pediatric and adolescent vaccine coverage remains low. Traditional vaccine reminders have had a limited effect on low-income populations; however, text messaging is a novel, scalable approach to promote influenza vaccination.

Among children and adolescents in a low-income, urban population, a text messaging intervention compared with usual care was associated with ...

Decision-making in the adolescent brain

Adolescence is characterized by making risky decisions. Early lesion and neuroimaging studies in adults pointed to the ventromedial prefrontal cortex and related structures as having a key role in decision-making. More recent studies have fractionated decision-making processes into its various components, including the representation of value, response selection (including inter-temporal choice and cognitive control), associative learning, and affective and social aspects. These different aspects of decision-making have been the focus of investigation in recent studies of the adolescent brain. Evidence ...

Adolescent impulsivity phenotypes characterized by distinct brain networks

The impulsive behavior that is often characteristic of adolescence may reflect underlying neurodevelopmental processes. Moreover, impulsivity is a multi-dimensional construct, and it is plausible that distinct brain networks contribute to its different cognitive, clinical and behavioral aspects. As these networks have not yet been described, we identified distinct cortical and subcortical networks underlying successful inhibitions and inhibition failures in a large sample (n = 1,896) of 14-year-old adolescents. Different networks were associated with drug use (n = 1,593) and attention-deficit hyperactivity disorder ...
