Brief Summary

The Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS) study is an interdisciplinary, community-based, prospective longitudinal epidemiologic study examining the influences of race and socioeconomic status (SES) on the development of age-related health disparities among socioeconomically diverse African Americans and whites in Baltimore. This study investigates whether health disparities develop or persist due to differences in SES, differences in race, or their interaction. HANDLS is unique because it assesses physical parameters as well as evaluating genetic, biologic, demographic, and psychosocial parameters of African American and white participants over a wide range of socioeconomic statuses, longitudinally. HANDLS also employs novel research tools, mobile medical research vehicles, in hopes of improving participation rates and retention among non-traditional research participants. The domains of the HANDLS study include: nutrition, cognition, biologic biomarkers, body composition and bone quality, physical function and performance, psychology, genomics, neighborhood environment and cardiovascular disease. Utilizing data from these study domains will facilitate an understanding of selected underlying factors of persistent black-white health disparities in overall longevity, cardiovascular disease, and cognitive decline. HANDLS recruited a fixed cohort as an area probability sample of Baltimore City from August 2004 through November 2009 as Wave 1. HANDLS Wave 2 entitled The Association of Personality and Socioeconomic status with Health Status - An Interim Follow-up Study began in June 2006 under a separate protocol. It was designed as a follow-up telephone interview approximately 18 months after the initial examination (Wave 1) was complete. Wave 2 provided interim contact with study participants, and important interim information regarding their health. Now completed, waves 3, 4 and 5 were follow-up examinations visits to our mobile Medical Research Vehicles (MRVs). In September 2020, HANDLS initiated wave 6; telephone interviews and limited in-person visits as a COVID-centric protocol. The current protocol outlines Wave 7, the fourth follow-up examination and the participants' fifth visit to our mobile Medical Research Vehicles (MRVs). Planned as a follow-up after 3-4 years, Wave 7 consists of health examinations, questionnaires, sensory assessments (visual and olfactory), health literacy assessment, renal function assessments, environmental assessments, and for a sub-set of participants; structural MRIs, a personality inventory and an examination of sleep and cognition under separate protocols. HANDLS will resume in-person examinations with wave 7 in which we will prioritize contacting participants who were not seen in wave 5.

Sampling MethodProbability Sample
Study Population

The baseline HANDLS sample consists of 3720 community-dwelling African American and white adults aged 30-64. Participants were drawn from 13 neighborhoods (groups of contiguous census tracts) in Baltimore City, sampling representatively across a wide range of socioeconomic and income circumstances.

You may qualify if:

  • Verified HANDLS participants (age 30-64 at baseline recruitment)
  • Able to give informed consent (or have a legal designee); and
  • Must have valid picture identification.

You may not qualify if:

  • Pregnancy
  • Current cancer chemotherapy or radiation therapy
  • Positive COVID test at point of care testing on examination visit date.
