Active clinical trials for "Obesity"

There are two aims for this study. The purpose of this study is to determine the effects of body weight and hormones on airway fibrosis (scarring) and lung function in obese & lean asthma subjects compared to obese & lean non-asthma subjects (Aim 1). And in obese subjects with asthma undergoing bariatric surgery compared to obese non-asthma subjects undergoing bariatric surgery (Aim 2).

The overall goal of this study is to examine the relationships between cultural identity and identity-based motivation, physical activity, diet and obesity risk in African-American adolescents. It was hypothesized that African-American youth who self-report a bicultural identity maintain health promotion beliefs and behaviors that reduce obesity risk compared to minority youth who only identify with one culture or neither culture. It was also hypothesized that African-American youth who self report a bicultural identity are more likely to hold beliefs about health promotion behaviors that are congruent with their cultural identity than compared to youth who only identify with one culture or neither culture.

Adiposity is a key link between lifestyle factors (like diet and exercise) and cardiovascular (CV) disease. However, little is known about the link during the juvenile years, when the processes leading to CV disease are at an early stage of development. The specific aims are as follow: (1) to determine the relations of free-living diet and exercise to total body percent fat ( percentBF), visceral adipose tissue and CV fitness in black and white boys and girls of varying socioeconomic status. (2) to determine the relations of fatness and fitness to different CV disease risk factors. Design and methods: (1) Recruit 800 14 to 18 year olds, 200 in each ethnicity and gender subgroup. (2) Assess diet with seven 24-hour recalls, and exercise with two seven-day recalls and heart rate monitoring. (3) Measure percent body fat with dual-energy x-ray absorptiometry, visceral adipose tissue with magnetic resonance imaging and CV fitness with a multi-stage treadmill test. (4) Measure major fatness- and fitness-related CV disease risk factors (e.g., total cholesterol:HDL cholesterol ratio, insulin, systolic blood pressure, left ventricular mass indexed to height, fibrinogen). (5) Conduct multivariate and univariate analyses to determine relationships.

In present study, we aimed to investigate the association between visceral adiposity index and overactive bladder symptoms in female patients aged over 18 years.Between January-2015 and July-2017, 151 female patient with overactive bladder symptoms were evaluated in Recep Tayyip Erdogan University Training and Research Hospital Urology Department. Antropometric and laboratory features including serum lipid levels, AST, ALT, fasting glucose levels, and also urodynamic findings were recorded. Visceral adiposity index was calculated according to gender-specific formula. Participants were divided into two groups according to 7,55 cut-off level for visceral adiposity index levels. Statistical significance were discussed between two groups.

This study investigates the chronic long-term health condition of obesity and its effect on neutrophil function and the inflammatory response

Background: - The Coronary Artery Risk Development in Young Adults (CARDIA) study is an investigation of cardiovascular risk factors among African-American and white young adults between 18 and 30 years of age, first recruited in 1985 86 from Birmingham, AL; Chicago, IL; Minneapolis, MN; and Oakland, CA. The study has examined a wide variety of risk factors, including insulin resistance, obesity, and diabetes. Based on 20 years of followup, the data provide evidence of an increase in the prevalence of many cardiovascular risk factors, as well as other factors that may lead to brain disease. To further evaluate these changes, the CARDIA Year 25 Exam will include a brain imaging component to study brain structure and function in a subset of CARDIA participants. Objectives: - To conduct brain magnetic resonance imaging as part of a 25-year followup study on participants in the original CARDIA study of heart disease risk factors in young adults. Eligibility: - Existing CARDIA study participants in the Minneapolis, MN, and Oakland, CA regions. Design: Participants will be screened with a full medical history and physical examination. - Participants will have an MRI scan at the 25-year followup examination for the CARDIA study. No additional testing or treatment will be required for this protocol.

R2C2 study has shown that abdominal obesity is associated with a cardiac and vascular remodelling in healthy volunteers. This remodelling is correlated with renin-angiotensin aldosterone system (RAAS) activation and/or systemic fibrosis. R2C2 II study is designed to confirm the hypothesis that RAAS is associated with an early remodelling and implicated in the transition to cardiac failure in abdominal obesity.

The purpose of this study is to improve the understanding of cellular mecanism involved in delivery disorders in obese women, first by characterizing the hyperplasia phenomenon of myometrail cells induced by inflammatory stimulation (Il-1B), then by studying the role of blood mononuclear cells, of leptine and of obese women sera to interfere with the transition of myometrial cells toward hyperplasia phenotype.

The objective of this study is to identify genes whose expression is potentially modifiable due to changes in folate intake and help delineate mechanisms accounting for the variability in individual response to folic acid supplementation. The study will be conducted in normal weight and obese women of childbearing age, supplemented for 8 weeks with 800 mcg/day folic acid. It is hypothesized that (1) a change in folate status, induced by the supplementation, will influence the DNA methylation of specific genes and (2) the DNA methylation response to folic acid supplementation may differ between the normal weight and the obese women of childbearing age.

Coordinated project whose objectives are: a) to assess the effectiveness of a physical activity intervention (MOVI-KIDS) on preventing obesity and improving fitness during the adiposity rebound period; and b) to examine the effectiveness of MOVI-KIDS on reducing the carotid intima-media thickness.
