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 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 ...

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 ...

Worldwide application of prevention science in adolescent health

The burden of morbidity and mortality from non-communicable disease has risen worldwide and is accelerating in low-income and middle-income countries, whereas the burden from infectious diseases has declined. Since this transition, the prevention of non-communicable disease as well as communicable disease causes of adolescent mortality has risen in importance. Problem behaviours that increase the short-term or long-term likelihood of morbidity and mortality, including alcohol, tobacco, and other drug misuse, mental health problems, unsafe sex, risky and unsafe driving, and violence ...

Adolescent Males’ Awareness of and Willingness to Try Electronic Cigarettes

Purpose

Electronic cigarettes (e-cigarettes) are a new type of device that delivers vaporized nicotine without the tobacco combustion of regular cigarettes. We sought to understand awareness of and willingness to try e-cigarettes among adolescent males, a group that is at risk for smoking initiation and may use e-cigarettes as a “gateway” to smoking.

Methods

A national sample of 11–19-year-old males (n = 228) completed an online survey in November 2011. We recruited participants through their parents, who were members of ...

Impulsivity-related personality traits and adolescent alcohol use: A meta-analytic review

Heightened impulsivity has been identified as a risk marker for excessive and problematic alcohol use, particularly during adolescence when impulsive behaviour is elevated and alcohol use is often initiated. Recent advances in personality theory indicate that impulsivity comprises several discrete traits which may influence alcohol use through different pathways. This review used meta-analysis to assess the degree to which the impulsivity-related traits of lack of premeditation, lack of perseverance, sensation seeking, negative urgency, positive urgency, and reward sensitivity are associated ...

Adolescent Substance Use in the Multimodal Treatment Study of Attention-Deficit/Hyperactivity Disorder (ADHD) (MTA) as a Function of Childhood ADHD, Random Assignment to Childhood Treatments, and Subsequent Medication

Objective

To determine long-term effects on substance use and substance use disorder (SUD), up to 8 years after childhood enrollment, of the randomly assigned 14-month treatments in the multisite Multimodal Treatment Study of Children with Attention-Deficit/Hyperactivity Disorder (MTA; n = 436); to test whether medication at follow-up, cumulative psychostimulant treatment over time, or both relate to substance use/SUD; and to compare substance use/SUD in the ADHD sample to the non-ADHD childhood classmate comparison group (n = 261).

Method

Mixed-effects ...

Health Effects of Media on Children and Adolescents

Youth spend an average of >7 hours/day using media, and the vast majority of them have access to a bedroom television, computer, the Internet, a video-game console, and a cell phone. In this article we review the most recent research on the effects of media on the health and well-being of children and adolescents. Studies have shown that media can provide information about safe health practices and can foster social connectedness. However, recent evidence raises concerns about media’s effects on ...

Impulsivity as a mechanism linking child abuse and neglect with substance use in adolescence and adulthood

Emerging developmental perspectives suggest that adverse rearing environments promote neurocognitive adaptations that heighten impulsivity and increase vulnerability to risky behavior. Although studies document links between harsh rearing environments and impulsive behavior on substance use, the developmental hypothesis that impulsivity acts as mechanism linking adverse rearing environments to downstream substance use remains to be investigated. The present study investigated the role of impulsivity in linking child abuse and neglect with adult substance use using data from (a) a longitudinal sample of ...

The influence of substance use on depressive symptoms among young adult black men: The sensitizing effect of early adversity: Depressive Symptoms and Substance Use in Black Men

Background and objectives: Depressive symptoms have been identified as an important consequence of substance use. Both heavy drinking and marijuana use have acute and short-term effects on systems that regulate emotion, increasing the potential for substance use to induce problems with negative affect and irritability. We investigated the effects of alcohol and marijuana use on depressive symptoms among a sample of young Black men. We also tested the stress sensitization hypothesis that exposure to adverse childhood experiences would amplify the ...

Mindful Parenting and Parents’ Emotion Expression: Effects on Adolescent Risk Behaviors

Mindful parenting is associated with greater adjustment and fewer behavior problems in children and adolescents. However, the mechanisms by which mindful parenting functions to mitigate risk in adolescence are not well understood. This study investigated parent emotional expression as a potential mechanism in the relationship between low mindful parenting and adolescent risk behaviors. A sample of 157 12–14-year-old adolescents (49 % female) and their primary caregivers (99 % female) participated in an emotionally arousing conflict interaction. Parents reported on their ...

Short-Term Effects on Family Communication and Adolescent Conduct Problems: Familias Unidas in Ecuador

Familias Unidas, a Hispanic/Latino-specific, parent-centered intervention, found to be efficacious in improving family functioning and reducing externalizing behaviors among youth in the USA, was recently adapted and tested for use in Ecuador. This study examined the short-term efficacy of Familias Unidas in Ecuador on parent-adolescent communication, parental monitoring of peers, and youth conduct problems. Two hundred thirty-nine youths (ages 12–14 years) and their primary care givers were randomized to either Familias Unidas or Community Practice and assessed pre- and post-intervention. ...
