Sentences with phrase «adverse early environment»

Although research in rodents supports this hypothesis, human research has been hampered by inconsistency in the types of adverse early environments studied and an inability to identify causal effects.

These advances will inform caregiving practices for the millions of abandoned and neglected children worldwide and inform the nature and timing of interventions for children exposed to a range of adverse early environments.

Adverse early environments create deficits in skills and abilities that drive down productivity and increase social costs — thereby adding to financial deficits borne by the public.

Not exact matches

Exposure to adverse early - life environments is associated with a range of negative developmental outcomes, including poor mental and physical health and atypical social functioning.

This pervasive pattern of stress response system hyporesponsivity is inconsistent with patterns observed in the rodent literature following maternal deprivation (1 ⇓ — 3, 46) and challenges some prevailing conceptual models of early - life adversity and stress response system development, which argue that adverse environments should lead to elevated physiological reactivity (47, 48).

Stress exposure in mature rodents is associated with immediate, but not lasting, changes in stress response systems (5, 6), suggesting the presence of an early sensitive period when exposure to adverse environments results in long - term changes in physiological stress response system functioning.

One interpretation of all of these findings is that the «good genes» somehow confer resiliency to adverse early rearing environments; another explanation is that a secure attachment confers resiliency to individuals carrying the «risky» allele.

Research most clearly demonstrating this relationship includes evidence that low childhood socioeconomic status (SES) predicts adult health outcomes, controlling for adult SES (13) and evidence that a harsh early family environment marked by abuse, conflict, cold nonnurturant parenting, or neglect predicts adverse health outcomes (12).

The cumulative adverse biological effects of chronic or recurring stress responses, in conjunction with genetic risks and those acquired in the early environment, in turn, lead to mental and physical health risks (10).

Males on this chronic physical aggression (CPA) trajectory tend to grow - up in adverse family environments [4], [7]--[9], have lower cognitive abilities [10], tend to be rejected by their peers from early childhood onwards [11] and have numerous physical, mental and social problems such as accidents, hyperactivity, school failure, substance abuse and unemployment [4], [5], [10], [12]--[14].

«The effects of adverse early childhood environments persist over a lifetime.»

Previous studies on telomere length in children focused on severe environmental adversities in early childhood such as living in institutions23 and prenatal tobacco exposure, 24 and demonstrated that the adverse living environment led to telomere shortening in exposed children.

Removing children from early learning environments also stigmatizes young individuals, contributing to numerous adverse social and educational outcomes.4 Research shows that young children who are suspended or expelled are more likely to experience academic failure and hold negative attitudes toward school, which contributes to a greater likelihood of dropping out of school and incarceration.5

Thus, differences in alpha power in middle childhood may reflect perturbed neural development as a function of adverse early life experiences and a violation of the expectable environment for young children across childhood.
