Collaborative Cohort of Cohorts for COVID-19 Research (C4R) Study: Study Design

Area of Science:

• Epidemiology
• Public Health
• Longitudinal Studies

Background:

• The COVID-19 pandemic poses significant public health challenges.
• Understanding risk and resilience factors for severe COVID-19 and its long-term consequences is crucial.
• Existing prospective cohort studies offer valuable pre-pandemic data.

Approach:

• The Collaborative Cohort of Cohorts for COVID-19 Research (C4R) is a national prospective study.
• C4R integrates 14 US-based cohort studies with extensive pre-pandemic data.
• Standardized protocols collect data on SARS-CoV-2 infection, COVID-19 illness, and outcomes.

Key Points:

• C4R links detailed pre-pandemic health and social data to COVID-19 outcomes.
• The study population is diverse, reflecting the US population across a wide age range.
• Leverages existing cohort infrastructure for high-quality data collection and retention.

Conclusions:

• C4R provides a unique resource for evaluating COVID-19 risk and resilience.
• The study will assess the pandemic's impact on long-term health and aging trajectories.
• Harmonized, pooled data will expedite collaborative research and scientific discovery.
