About this study
To define the relation of insulin resistance during childhood and adolescence to the development of the insulin resistance syndrome in young adulthood.
Read the detailed description
BACKGROUND:
The insulin resistance syndrome (IRS) is associated with a considerable increase in the risk of cardiovascular disease in adults. The disorder most likely is inherited to some degree with onset in childhood and early adolescence. The IRS is best defined by quantitative data from euglycemic insulin clamp studies. The investigators have developed a unique data base in children, and by continuing repeated studies and follow-up in early adulthood together with studies in parents and siblings this study should provide important insight into the occurrence and progression of cardiovascular disease in later life.
DESIGN NARRATIVE:
The study is designed to: 1) define the relation of insulin resistance during childhood and adolescence to the development of insulin resistance syndrome (hypertension, dyslipidemia, obesity, and insulin resistance) in young adulthood; and 2) define the relation of insulin resistance within families. The original cohort consists of 357 children who have had two euglycemic insulin clamp studies (at mean ages 13 and 15 years). The specific aims are: to (1) repeat anthropometric and blood pressure measurements at mean ages 18, 19, and 20 and obtain insulin clamps, lipid levels, echocardiograms, and DEXA at mean age 21 in the children; and (2) obtain the measurements, blood and DNA samples, echocardiogram, and insulin clamp in the parents and siblings of the children. Statistical genetics methods are used to estimate heritability and genetic correlations among the insulin resistance syndrome traits. These data address the hypotheses that 1) insulin resistance in childhood predicts insulin resistance and cardiovascular risk factors in young adulthood; 2) insulin resistance in parents is associated with insulin resistance and cardiovascular risk factors in their children; 3) in fat children, BMI and insulin resistance at mean age 13 predicts cardiovascular risk, but in thin children only insulin resistance is a similar predictor; 4) insulin resistance has significant heritability; and 5) there are significant genetic correlations between insulin resistance and the insulin resistance traits. At least 300 of the original cohort of 357 who have had two euglycemic insulin clamps continue on in the study. The study continues through July, 2008.

Questions about this trial
What is this clinical trial studying?
An observational study of Cardiovascular Diseases and Hypertension, run by University of Minnesota.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 7 Dec 2016. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00007098, which also lists 13 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Dec 2016.
