The RIGHT Track Health Study investigates how self-regulatory behaviour throughout childhood alters the trajectories of various cardiovascular risk factors during late adolescence via health behaviours. Between 1994 and 2001, almost 450 participants were recruited into three cohorts through childcare centres and local health services in North Carolina, United States of America. Baseline assessments were conducted when the participants were 2 years old, with Cohort 3 also completing a preliminary assessment at recruitment when 6 months old. Further follow-ups occurred when the participants were 4, 5, 7, and 10 years of age. In 2014, an additional follow-up assessment was conducted when participants were in their late teens.
