Context: Adiponectin is an adipose tissue-derived hormone with an insulin sensitizing effect, and has been related to obstructive sleep apnea syndrome. In addition, children with Prader-Willi syndrome (PWS) suffer from excessive daytime sleepiness and the abnormality of rapid eye movement (REM) sleep.

Objective: To determine if the sleep stages are related to the plasma levels of adiponectin, resistin, and RBP4 (retinol binding protein-4), and whether these relationships are influenced by age, obesity and insulin resistance.

Enrollment: 46
Study Start Date: January 2007
Study Completion Date: June 2007
Detailed Description:
This comparative study was carried out in 28 PWS children and 18 controls. The enrolled PWS children were volunteers out of a pool of approximately 100 PWS children followed at Samsung Medical Center [median age 8.0 years, interquartile range (7.0-10.5 years), BMI: median 24.2 kg/m2 (23.0-27.5 kg/m2)] and 18 obese healthy children [median age 9.0 years interquartile range (7.0-11.0 years), BMI: median 24.2 kg/m2 interquartile range (23.1-27.6 kg/m2)].

Ages Eligible for Study:   5 Years to 12 Years   (Child)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Sampling Method:   Probability Sample
Study Population
The study population comprised 28 children with PWS and 18 controls. The enrolled children with PWS were volunteers from a pool of approximately 100 children with PWS followed up at the Samsung Medical Center. The controls were healthy children from several elementary and middle schools located in the southern areas of Seoul.
