A biobehavioral perspective on telomere length and the exposome

Area of Science:

• Biobehavioral research
• Genomics
• Environmental health

Background:

• Biobehavioral research aims to link behavior, biology, health, and disease mechanisms.
• The exposome concept highlights lifelong environmental exposures and their impact on health.
• Telomere length (TL) and stability factors are emerging biomarkers for aging and stress-related diseases.

Purpose of the Study:

• To explore the role of telomere length (TL) in understanding gene-environment interactions within the exposome framework.
• To investigate how various exposures influence TL and contribute to disease risk.
• To bridge biobehavioral research with exposome science for improved health outcomes.

Main Methods:

• Review of existing literature on biobehavioral research, genomics, and the exposome.
• Analysis of the relationship between environmental exposures and telomere biology.
• Conceptual integration of TL as a biomarker within the exposome model.

Main Results:

• Gene-environment interactions are crucial for health outcomes, with the exposome providing a comprehensive measure.
• Telomere length (TL) is influenced by internal and external exposures, both modifiable and nonmodifiable.
• TL serves as a significant biomarker for aging and stress-related conditions.

Conclusions:

• Incorporating TL into biobehavioral research, considering exposome factors, is essential.
• Future exposome research will illuminate exposure sources, dosage, and duration affecting telomere biology and disease.
• Findings can inform personalized disease prevention and treatment strategies.
