Filter by:Overall mortality, such as that caused by cardiovascular disease, increases as weight increases. In the Framingham Study, it was shown that obesity is a cardiovascular risk factor independent of other risk factors such as type 2 diabetes mellitus, dyslipidemia and smoking. Objectives: 1. To determine whether a group motivational intervention is more effective than the standard intervention for treatment of overweight and obesity and most importantly to maintain the attained weight loss on a permanent basis. 2. To assess whether this intervention is more effective than reducing cardiovascular risk factors (lipid profile, apo B-100, apo A-1, fibrinogen, C-reactive protein, hypertension, diabetes mellitus) associated with overweight and obesity, and the overall cardiovascular risk in these patients. Design: Randomized, multicenter, interventional clinical trial in patients with overweight and obesity. Randomized assignment of the intervention by Basic Health Areas (BHAs). Two groups will be established in geographically separate areas, one of which will receive the group motivational intervention (intervention group) and the other will receive standard follow-up (control group). BHAs located in the same building will be assigned the same group (control or intervention) to avoid potential contamination. hypertensive treatment or with a diagnosis of hypertension in their clinical history. Study Scope: Primary care. The study will be conducted in 24 BHAs of Hospitalet de Llobregat and Barcelona during 26months follow-up period. Haematic analyses will be in the carried out at the reference laboratory.
A 12 wk aerobic exercise program will reduce visceral, hepatic and intramyocellular fat accumulation and improve insulin sensitivity and glucose metabolism in obese sedentary Hispanic adolescents.
The overall objective of this study is to investigate in depth the nature of metabolic physiology, body composition and epigenetic differences of the different phenotypes of overweight and obese individuals who are otherwise overtly healthy among the three major ethnic groups in Singapore.
This study examines risk factors for type 2 diabetes in children representing multiple discrete ethnic groups. It also examines the short term effects of school-based health education supervised exercise on metabolic risk factors for type 2 diabetes mellitus in children. The investigators hypothesize that exercise and health education will significantly improve insulin sensitivity in all children, especially in children who are already insulin resistant, thereby lowering the risk that they will go on to develop type 2 diabetes mellitus. The specific hypotheses being tested are: 1. Insulin resistance will be most evident in overweight children while an impaired ability of the pancreas to release insulin will be most evident in children with a family history of type 2 diabetes mellitus. 2. Exercise will significantly improve insulin resistance (as measured by the fasting glucose/insulin ratio) with little effect on insulin secretory capacity in children. 3. Participation in a school-based health, nutrition, and exercise education program will have long term beneficial effects on health related behaviors and on insulin resistance in all children, regardless of their level of diabetes risk.
Obesity has been found to be a risk factor for female infertility. Studies have indicated that obese men often have poor semen quality and require increased time to make partner pregnant. To date, no studies have investigated the effect of weight reduction on male fertility. The purpose of this study is to investigate the effect of weight reduction in overweight and obese men on their reproductive function.
The investigators aim to study the effects of green tea and maté consumption on lipid and inflammatory profiles in dyslipidemic and overweight subjects.
The purpose of this study is to learn if obese pre- and early pubertal girls with hyperandrogenemia (HA) are more insulin resistant (i.e., have lower insulin-stimulated glucose disposal) compared to obese peripubertal girls without HA; and that overnight mean luteinizing hormone (LH) concentration is also an independent predictor of free testosterone concentrations, especially in mid- to late pubertal girls.
The Danish Childhood Obesity Biobank aims to produce a scientific platform for research in obesity: Bio-clinical data are collected from two cohorts - an obesity clinic cohort and a population-based cohort. The biobank thus facilitates translation between research and clinical practice of obesity treatment and related complications.
The objectives of the present study are: 1. to evaluate if overnight weight loss is dependent on sleep structure assessed by polysomnography; 2. to compare weight loss rate during sleep and awake rest; 3. to compare night weight loss profile of normal and obese volunteers.
Sildenafil has been shown to aggravate sleep-disordered breathing in patients with severe obstructive sleep apnea. The aim of the present study is to examine the frequency of sleep-disordered breathing in obese patients who are candidates for treatment with sildenafil for sexual dysfunction. In addition we wish to assess the effect of sildenafil on sleep-disordered breathing.
