Identification of Predictors of Success for Lifestyle Modifications in Overweight Pre-diabetic Subjects

2014-08-27 03:19:38 | BioPortfolio

Summary

The primary objective of the study is to identify baseline and early predictors of favorable and unfavorable response to lifestyle intervention. As a secondary objective, the investigators would like to validate our questionnaire or other identified predictors as clinical tools to guide us in selection of the most suitable candidates for lifestyle intervention programs. Assuming the same capacity of our questionnaire to predict an absence of weight loss (≥5%) or a loss to follow-up (likelihood ratio for a positive test, LR+ = 9.9), 70 subjects need to be included in this study in order to find a lower limit of the 95% confidence interval above 2.0 for this LR+, which is the limit of an acceptable test. The investigators will enroll participants with pre-diabetes and BMI 27-40 in our program and administer to them at baseline and at 3 months the designed questionnaire, as well as other already well validated questionnaires assessing state of change and readiness to implement diet or exercise modifications.

Medical and Biotech [MESH] Definitions

A pathological state in which BLOOD GLUCOSE level is less than approximately 140 mg/100 ml of PLASMA at fasting, and above approximately 200 mg/100 ml plasma at 30-, 60-, or 90-minute during a GLUCOSE TOLERANCE TEST. This condition is seen frequently in DIABETES MELLITUS, but also occurs with other diseases and MALNUTRITION.

A heterogeneous group of disorders characterized by HYPERGLYCEMIA and GLUCOSE INTOLERANCE.

Maintenance of a constant blood glucose level by perfusion or infusion with glucose or insulin. It is used for the study of metabolic rates (e.g., in glucose, lipid, amino acid metabolism) at constant glucose concentration.

An enzyme which catalyzes the hydrolysis of LACTOSE to D-GALACTOSE and D-GLUCOSE. Defects in the enzyme cause LACTOSE INTOLERANCE.

A glucose transport facilitator that is expressed primarily in PANCREATIC BETA CELLS; LIVER; and KIDNEYS. It may function as a GLUCOSE sensor to regulate INSULIN release and glucose HOMEOSTASIS.
