"The primary objective [of HANDLS] is to create a representative 20-year longitudinal study of health status across the lifespan focused on investigating the differential influences of race and socioeconomic status on health in an urban population. The study recruits whites and African Americans 30-64 years old from the City of Baltimore, Maryland, in both low and high socioeconomic status. Data collection includes a baseline assessment and five follow-up triennial assessments over approximately 20 years." |
