Summary
Childhood adversity, including parent relational instability, is linked to shorter telomeres in adolescents. Continuous exposure to adversity may impact telomere length, potentially affecting long-term health outcomes.
Area of Science:
- Adolescent Health
- Genetics
- Childhood Development
Background:
- Childhood adversity is linked to adult health issues.
- Telomere shortening may be a key mechanism connecting adversity to poor health.
- Understanding these links is crucial for early intervention.
Purpose of the Study:
- To investigate the association between different types of childhood adversity and telomere length in adolescents.
- To examine the impact of adversity across multiple developmental epochs (childhood and adolescence).
- To identify specific adversities that may influence telomere shortening.
Main Methods:
- Longitudinal cohort study involving 879 youth aged 11-17 and their caregivers.
- Caregivers completed questionnaires on demographics and adversity.
- Youth provided saliva samples for DNA extraction and telomere length analysis.
Main Results:
- Over half of the youth experienced some form of adversity.
- Parental relational instability across two or three epochs was associated with shorter telomeres (p < .004).
- Child household instability (2 epochs) and financial instability (3 epochs) also correlated with shorter telomeres (p = .003 and p = .013, respectively).
Conclusions:
- Persistent exposure to adversity during early development may significantly affect telomere length.
- Further research is needed to pinpoint specific adversities with the greatest impact.
- Investigating the long-term health implications of early telomere shortening is essential.

3.6K
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...

02:41Telomeres and Telomerase
23.0K
In eukaryotic DNA replication, a single-stranded DNA fragment remains at the end of a chromosome after the removal of the final primer. This section of DNA cannot be replicated in the same manner as the rest of the strand because there is no 3’ end to which the newly synthesized DNA can attach. This non-replicated fragment results in gradual loss of the chromosomal DNA during each cell duplication. Additionally, it can induce a DNA damage response by enzymes that recognize single-stranded...

13.1K
In eukaryotic cells, DNA replication is highly conserved and tightly regulated. Multiple linear chromosomes must be duplicated with high fidelity before cell division, so there are many proteins that fulfill specialized roles in the replication process. Replication occurs in three phases: initiation, elongation, and termination, and ends with two complete sets of chromosomes in the nucleus.

01:10Nature and Nurture
20.4K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

01:28Adler's Individual Psychology
501
Alfred Adler, a prominent figure in psychology, founded the school of individual psychology. In contrast to Freud's emphasis on sexual or aggressive motives, Adler suggested that individuals are primarily motivated by their purposes and goals. He believed that people strive for perfection rather than pleasure. Adler argued that individuals could creatively act upon their genetic inheritance and environmental experiences to shape their own lives, emphasizing conscious motivation over...
