Issues and Solutions for Collecting Biological Specimen in Longitudinal Studies: Experience from the Community Child...

Area of Science:

• Environmental Health
• Public Health
• Biomarkers in Research

Background:

• Biomarkers for stress and health outcomes are increasingly studied, particularly within community-based participatory research (CBPR).
• Community and participant perspectives are often underrepresented in the biomarker collection process.
• Allostatic load is a key indicator of cumulative stress impacting health.

Purpose of the Study:

• To describe the process and outcomes of integrating CBPR into biomarker collection for a maternal and child health study.
• To explore how CBPR influences community trust and endorsement of biological sample collection.
• To incorporate community priorities into the design of biomarker data collection protocols.

Main Methods:

• Utilized focus group data analysis to understand community perspectives on biomarker collection.
• Employed a community-based participatory research (CBPR) framework.
• Focused on a maternal and child health population study examining allostatic load.

Main Results:

• CBPR fostered increased community trust and endorsement for collecting biological samples.
• Community members gained a better understanding of the importance of biomarkers.
• The biomarker data collection protocol was adapted to reflect community priorities and scope.

Conclusions:

• CBPR is effective in building trust and understanding for biomarker research in community settings.
• Integrating community perspectives into study design enhances the relevance and acceptance of biomarker collection.
• CBPR leads to more responsive and community-aligned health research protocols.
