Genetics of Obesity, Diabetes, and Heart Disease in African Diaspora Populations
United States1,100 participantsStarted 2011-05-06
Plain-language summary
Background:
\- African Americans have one of the highest rates of type 2 diabetes in the United States, and often have other medical problems related to obesity and cardiovascular disease. These conditions have various risk factors, including high blood sugar levels, high cholesterol levels, and insulin resistance. However, these risk factors have not been studied very closely in individuals with African ancestry, including Afro-Caribbean and sub-Saharan Africa migrant populations. Researchers are interested in conducting a genetic study on obesity, adult-onset diabetes, heart disease, and other common health conditions in individuals with African ancestry.
Objectives:
\- To collect genetic and non-genetic information from individuals with African ancestry to study common health conditions related to obesity, adult-onset diabetes, and heart disease.
Eligibility:
\- Individuals at least 18 years of age who self-identify as African American, Afro-Caribbean, or migrants from sub Saharan Africa.
Design:
* Participants will undergo a physical examination and will provide a blood sample for study.
* Participants will also answer questions about personal and family medical history and current lifestyle behaviors.
* No treatment will be provided as part of this protocol.

* INCLUSION CRITERIA:
Subjects will include unrelated persons who self-identify as white or African American, Afro-Caribbean or migrant from sub-Saharan Africa. Adults of African ancestry are prioritized for this study because of the paucity of genetics studies investigating the association of risk alleles contributing to the prevalence of T2D, CVD, obesity and other common conditions in this population. A small proportion of whites (less than 10%) will be included in this study, as they are in Dr. Sumner's ongoing projects; they will have the same clinical measurements obtained in the same laboratory to serve as a comparison group. This study only includes adults because these phenotypes are more commonly present in adults. In summary, inclusion criteria include:
* Persons who self-identify as either
* African American
* Afro-Caribbean
* A migrant from sub-Saharan Africa
* White
* Persons \>= 18 years
* Participation in a protocol with Dr. Anne Sumner, NIDDK
EXCLUSION CRITERIA:
Related individuals are excluded to avoid biases in our analyses due to genomic similarities between people who are related. Adults unable to consent will be included in this study. Pregnant women are excluded from this study because pregnancy induces changes in metabolism that would interfere with the measurements and outcomes of the study. In summary, exclusion criteria include:
* Individuals related to participants (any known familial relationship, as reported by the prospective enrol…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
