Active clinical trials for "Overweight"

Background: Obesity is associated with alterations in iron metabolism leading to iron deficiency. Aim: to study the prevalence of obesity among primary school students, assess iron status among overweight/obese children with age ranging between 6 and 12 years and the effect of weight reduction program on iron status. Patients and Methods: The study will be conducted on 2 groups. Group 1 will include 1025 primary school children recruited from 2 urban schools in Cairo with age ranging between 6 and 12. Anthropometric measures and prevalence of overweight/obesity will be assessed. Group 2 will include 100 obese children according to the CDC definition and 50 age and sex matched children with normal weight. All will be subjected to history taking, anthropometric measures, complete blood picture, iron profile and soluble transferrin receptor. Weight reduction program for 6 months will be done for obese children and all parameters will be re-ckecked.

The purpose of this study is to to assess the glycemic index and the satiating properties of different Quinoa varieties, using a Visual Analogue Scale in a sample of healthy overweight subjects.

The objective of this randomized, single blinded cross-over study is to investigate effects of daily egg versus yolk-free egg substitute consumption on High Density Lipoprotein (HDL) composition and function in a population of overweight and obese postmenopausal women.

Objective. To evaluate the effect of the intake of two types of whole corn tortilla and one traditional tortilla on glycemic index (GI) and insulinemic index (InIn) in adults with diabetes, or overweight or clinically healthy. Material and methods. Type crossover clinical trial in adults 20-69 years. Three groups of participants will be included for each category (n = 27 in each group): 1) adults with diabetes, b) adults with overweight c) clinically healthy adults. The glycemic and insulinemic index will be measure for each group of participants given in random order the following foods: 1) a whole corn tortilla (white "criollo" corn= 5.3% fiber), 2) a whole corn tortilla (white "hybrid" corn= 7.9%), 3) a traditional corn tortilla (3.9% fiber), and 4) white bread (reference food containing 2.2% of fiber). For the calculation of GI and InIn will be follow the "FAO" methodology. For the evaluation of each food left the range of 1 week.

The aim of this study is to investigate if dark chocolate rich in polyphenols decreases body weight/ body fat in the overweight and obese adult population.

The study aims are to develop and test the feasibility of a pediatric physical activity intervention that incorporates personal information on use of the built environment, and test the intervention's preliminary efficacy at increasing physical activity. The investigators hypothesize that it will be feasible to incorporate and measure changes in empiric GIS (geographic information system), GPS (global positioning system), and accelerometer feedback in the office setting as demonstrated by: i) Completeness of GPS and accelerometer data collection (primary measure of feasibility), ii) Participation rates among adolescents in the intervention group compared to the control group, and iii) Acceptability to patients as measured by adolescent satisfaction.

The study will compare Concord grape juice to a beverage that contains no grape flavonoids, but has a similar appearance and taste (placebo juice). A total of 60 overweight and obese participants over age 50 will be enrolled. Each participant will drink each beverage for 4 weeks with a 2-week rest period between two beverage consumption periods. The order of beverages (grape juice first or placebo juice first) will be randomized. The investigators will use ultrasound to measure brachial artery flow-mediated dilation, a measure of endothelial vasodilator function. The investigators will also collect blood samples to further assess the cardiovascular effects of grape juice. The aim of the study is to determine whether Concord grape juice improves endothelial function in patients at risk who do not have cardiovascular disease and may provide information that would guide dietary recommendations. The results may also be used by the sponsor to substantiate claims and labeling of their product.

A diet high in easily obtained energy-dense foods leads to the problems of overweight and obesity common in the developed world. Foods enriched with fiber or bitter compounds may increase satiety and decrease energy intake. This intervention will measure the effectiveness of coffee melanoidins, bread melanoidins, beta-glucans, and a Gentiana lutea L. extract in both a free or encapsulated form to decrease energy intake and modify the physiological markers of satiety in the short term. In particular bread (fiber) and a pudding (Gentiana lutea L. extract) will be used as tasty food matrices in the study.

The aim of this study is to examine the effects of soy fiber on body weight, body composition and blood lipids in overweight and obese participants.

The primary objective of the proposed study is to examine and understand the impact of long-term almond consumption on chronic glucose metabolism in subjects with impaired glucose tolerance and/or impaired fasting glucose.
