Future of Families: Cardiovascular Health Among Young Adults Cohort Study: Rationale, Key Questions, Study Design,...

Area of Science:

• Cardiovascular Health
• Social Epidemiology
• Developmental Origins of Health and Disease

Background:

• Childhood social determinants of adult cardiovascular health and their mechanisms remain unclear.
• The Future of Families-Cardiovascular Health Among Young Adults (FF-CHAYA) study aims to fill this knowledge gap.
• Understanding these links is crucial for public health interventions.

Purpose of the Study:

• To examine associations between childhood social determinants and cardiovascular health in young adulthood.
• To investigate potential epigenetic mechanisms mediating these associations.
• To characterize early arterial injury in young adults based on early life exposures.

Main Methods:

• FF-CHAYA is a subcohort of the Future of Families and Child Wellbeing Study, tracking offspring from birth to age 22.
• In-person examinations included health status questionnaires, anthropometry, blood pressure, phlebotomy, and carotid ultrasonography.
• Cardiovascular health was assessed using the Life's Essential 8 score and carotid intima-media thickness, grayscale lucency, and distensibility.

Main Results:

• The study included 1975 nonpregnant participants with a mean age of 23.2 years.
• Participants represented diverse racial/ethnic backgrounds, with a mean BMI of 29.0 kg/m².
• The mean Life's Essential 8 score was 69.2, indicating significant variation by demographic groups and evidence of accelerated early arterial injury.

Conclusions:

• The FF-CHAYA cohort provides a novel longitudinal dataset to study childhood social factors and young adult cardiovascular health.
• Findings highlight accelerated early arterial injury, suggesting long-term cardiovascular risks.
• The study is poised to elucidate epigenetic mechanisms linking early life exposures to later cardiovascular outcomes.
