Active clinical trials for "Glucose Intolerance"

This is an observational study to understand the glucose characteristics of the general population (normal glucose, pre-diabetes, and diabetes). Glucose risk will be measured with laboratory HbA1c and continuous glucose monitor (CGM) derived metrics. Physical activity will also be measured using a Fitbit activity tracker. The study will inform future programs that use CGM and activity tracking to identify people at risk for diabetes in the population.

As an important way to translate cardiovascular disease prevention efforts, worksite interventions can facilitate healthy food choices, health education, and social support. This proposed project is adapted and scaled-up from the Nepal study, and will measure the effectiveness of a canteen and a behavioral intervention on cardio-metabolic risk at a worksite in South Africa. This study will estimate the added benefit of a proven individual-level dietary intervention over environmental-level changes for preventing cardio-metabolic risk within the South African context. If the study demonstrates a significant effect, a scaled-up approach could produce an important reduction in cardiovascular disease burden through environmental and individual level prevention programs in South Africa.

The main purpose of the clinical trial is to determine the health impact of a dietary intervention known as time-restricted eating (TRE) in patients with metabolic syndrome (defined as the presence of elevated fasting plasma glucose and two or more of the following criteria: increased waist circumference, elevated fasting plasma triglycerides, reduced high-density lipoprotein-cholesterol, elevated blood pressure) and self-reported dietary intake of ≥14 hours per day. Participants will reduce the amount of time they eat to 10 hours per day over a 12-week monitored intervention followed by a 12-week self-directed intervention and will log their dietary intake using a smartphone application (myCircadianClock (mCC) app). Glucose homeostasis (blood glucose levels will be monitored continuously for 2 weeks at the baseline, at the end of the monitored intervention, and at the end of the self-directed intervention using a continuous glucose monitor), and other metabolic, neuroendocrine, inflammatory and oxidative stress/antioxidant defense biomarkers, body weight and composition, blood pressure, heart rate, sleep and activity (using mCC app), personal sense of wellness and dietary timing (using health questionnaires) will be evaluated at the baseline, at the end of the monitored intervention, and at the end of the self-directed intervention.

The objective of this study is to compare the glycemic and insulinemic response elicited by ½ cup servings of 6 beans to those elicited by ½ cup servings of mashed potato, macaroni, rice and corn.

Assessment of glucose metabolism and liver fat after 12 week dietary intervention in pre diabetes subjects. Subjects will be randomized to either high fat (olive oil supplemented),high carb/high fiber (beans supplemented) and high carb/low fiber diets. Glucose metabolism will be assessed by labeled oral glucose tolerance test and liver fat by magnetic resonance spectroscopy pre randomization and at 8 and 12 week after starting dietary intervention.

The purpose of this study is to compare the glycemic index of a beverage made of natural concentrated mango puree with natural concentrated pear juice with other five different products based on natural mango and pear ingredients in the form of fruit or juice against a control of 50-gram glucose load.

Experiments have shown that some artificial sweeteners like those in diet soda can cause changes in how the body responds to and uses sugar. These changes increase the chance of obesity, type 2 diabetes, and other metabolic diseases. In this study, the investigators plan to see if the most common artificial sweetener, aspartame (brand name Equal, NutraSweet), causes these changes. The investigators believe that if metabolic changes are observed in a person who consumes aspartame, then removing all aspartame from the diet might lead to a reversal of the changes and a normalization of test results.This would impact sweetener additives in our foods and thus decrease the incidence of obesity, diabetes, and the metabolic syndrome.

The incidence rate of type 2 diabetes in Thai populations is high and increasing every year. Cardiovascular disease is the main complication of this disease, which has been defined as an important cause of death among Diabetic patients. This disease is now becoming a major health problem and causes a great economic loss to the country. Evidence shows that Curcumin, Thai herbal medicine, has the effectiveness of prevention and delay of type 2 diabetes. However, there is no scientific study that aims to prove the efficacy of this herb particularly for prevention and delay the disease in Patients with impaired glucose tolerance (pre-diabetes) and insulin resistance.

To study the effect of cinnamon on postprandial blood glucose, and plasma concentrations of insulin in subjects with impaired glucose tolerance.

Though anti-HIV drugs can dramatically improve the health of people with HIV, some people taking these drugs develop serious long term effects in their metabolism. These effects include problems with bones, increased levels of blood sugar and lipids, and changes in body fat distribution. The purpose of this study is to see how many young women are experiencing these problems and how severe the problems are. This kind of study is the first step in determining how best to treat these problems.
