Responsible research in health disparities using the Adolescent Brain Cognitive Development^SM (ABCD) study

Area of Science:

• Neuroscience and Public Health
• Adolescent Development Research
• Health Disparities Science

Background:

• The Adolescent Brain Cognitive Development (ABCD) Study is a large, longitudinal US study tracking brain development and health in nearly 12,000 diverse youth.
• The study's open science model facilitates rapid data sharing, leading to over 1100 publications since 2018.
• The ABCD dataset includes comprehensive measures of behavioral, health, brain outcomes, and social determinants of health (SDOH).

Purpose of the Study:

• To provide guidance on the appropriate, responsible, and equitable use of ABCD Study data for health disparities research.
• To identify multilevel pathways through which structural inequities impact adolescent health.
• To inform early-life interventions for preventing adult health disparities.

Main Methods:

• Developed a conceptual framework integrating NIMHD Research Framework with strength-based and data equity perspectives.
• Identified over fifty ABCD measures encompassing SDOH across individual, interpersonal, school, community, and societal levels.
• Applied a multi-level analytical approach to examine the influence of social and structural inequities on youth cognitive decision-making.

Main Results:

• Over fifty ABCD measures were identified as relevant for assessing SDOH across five levels.
• Structural discrimination was highlighted as a root cause of health disparities among marginalized youth.
• An example analysis demonstrated how social and structural inequities may influence cognitive decision-making in adolescents.

Conclusions:

• Adolescence is a critical developmental period influencing lifelong health outcomes.
• Understanding SDOH in diverse youth populations is crucial for developing targeted prevention interventions.
• Recommendations are provided to enhance the utility of ABCD data for future health disparities research.
