Study Description

Brief Summary

The Healthy Aging in Neighborhoods of Diversity across the Life Span study (HANDLS) is a multidisciplinary, 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. This study is unique because it will assess over a 20-year period physical parameters as well as evaluate genetic, biologic, demographic, and psychosocial parameters of African American and white participants in higher and lower SES. It 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, sociodemographics, psychosocial, neighborhood environment and cardiovascular disease. Utilizing data from these study domains will facilitate understand the driving factors behind 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 and 4 were the first and second follow-up examinations and participants second and third visit to our mobile Medical Research Vehicles (MRVs). The current protocol outlines Wave 5, the third follow-up examination and participants fourth visit to our mobile Medical Research Vehicles (MRVs). Planned as a follow-up after 3-4 years, Wave 5 consists of health examinations, questionnaires, a telephone dietary-recall interview, sensory assessments (visual, olfactory), health literacy assessment, skin color analysis, renal function assessments, environmental assessments and structural MRIs.

Detailed Description

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. Planned as a 20-year longitudinal study, 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. HANDLS also employs novel research tools, mobile medical research vehicles, in hopes of improving participation rates and retention among nontraditional 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 inperson examinations with wave 7 in which we will prioritize contacting participants who were not seen in wave 5.

Health Outcomes

Eligibility Criteria

Criteria

Ages Eligible for Study:

30 Years to 64 Years

Sexes Eligible for Study:

All

Accepts Healthy Volunteers:

INCLUSION CRITERIA:
Verified HANDLS participants (age 30-64 at baseline recruitment)
Able to give informed consent (or has a legal designee)
Must have valid picture identification

EXCLUSION CRITERIA:

Pregnancy (for the MRV examination visit and the HANDLS Scan sub-study a urine pregnancy test is performed with women of child bearing potential during the medical screening prior to any testing or procedures. If positive, participant will not be eligible for the MRV examination visit until they are no longer pregnant. Participants with a positive pregnancy test will be invited to return for the MRV examination visit and/or the HANDLS Scan once pregnancy is resolved (pregnancy testing is repeated at each encounter, if indicated). The Diabetes sub-study home visit protocol does not pose increased risk so pregnancy status is not required or obtained)
Current cancer chemotherapy or radiation therapy
