A to Z Study Follow-up: Collection of DNA Data From Buccal Swabs
2009年3月19日 更新者：Interleukin Genetics, Inc.
The goal of this study is to determine the association between genotypes and diet.
The weight and weight loss data are already available from the previously completed study called: A to Z Study - Benefits and Risks of Alternative Weight Loss Strategies - A Clinical Trial, which was performed from 2003-2005 at Stanford University.
In the present study, Interleukin Genetics will obtain DNA samples from the previously enrolled study subjects to investigate genetic influence of the response to macronutrient compositions of low caloric diets to weight loss.

详细说明
Interleukin Genetics has derived, through an extensive search of the scientific literature, a genetic test panel in the area of Weight Management (WM), which includes the genes that have been shown to affect body weight.
These genes have been associated with elevated risk for obesity.

研究人群
The study population for the A to Z study are premenopausal women who are overweight (BMI 27-40 kg/m2) but in otherwise good general health.
Overweight participants with potentially confounding health conditions are excluded (eg., hypertension, diabetes, heart disease, cancer).
Children were not included in this study.
The participants were asked to agree to a random assignment to dietary plans.
