Hormonal and Metabolic Consequences of Sleep Disorders in Young Obese Patients
There is a well-documented relationship between short sleep duration and high body mass index (BMI). The mechanism linking short sleep duration and weight gain is unknown. Current studies in healthy young volunteers have shown that experimental sleep restriction is associated with dysregulation of the neuroendocrine control of appetite and with alterations in glucose metabolism. The goal of our study is to determine the metabolic and hormonal modifications induced by chronic sleep curtailment in obese adolescents and young adults and to observe if short sleep is a negative prognostic factor in their weight evolution.
The main purpose of the study is investigate whether the concentrations of 2 hormones that regulate appetite (leptin, ghrelin), cytokines (TNF-a, IL-6) and CRP are modified in obese adolescents and young adults who had sleep disorders in comparison to obese adolescents and young adults who sleep longer.

Medical and Biotech [MESH] Definitions
A condition of having excess fat in the abdomen. Abdominal obesity is typically defined as waist circumferences of 40 inches or more in men and 35 inches or more in women. Abdominal obesity raises the risk of developing disorders, such as diabetes, hypertension and METABOLIC SYNDROME X.
The condition of weighing two, three, or more times the ideal weight, so called because it is associated with many serious and life-threatening disorders. In the BODY MASS INDEX, morbid obesity is defined as having a BMI greater than 40.0 kg/m2.
Agents that increase energy expenditure and weight loss by neural and chemical regulation. Beta-adrenergic agents and serotoninergic drugs have been experimentally used in patients with non-insulin dependent diabetes mellitus (NIDDM) to treat obesity.
A status with BODY WEIGHT that is grossly above the acceptable or desirable weight, usually due to accumulation of excess FATS in the body. The standards may vary with age, sex, genetic or cultural background. In the BODY MASS INDEX, a BMI greater than 30.0 kg/m2 is considered obese, and a BMI greater than 40.0 kg/m2 is considered morbidly obese (MORBID OBESITY).
The discipline concerned with WEIGHT REDUCTION in patients with OBESITY.
