Peculiar features of obesity and metabolic disorders in the children presenting with Prader-Willi syndrome

Aim. The nalysis of peculiar features of obesity and metabolic disorders in the children presenting with Prader-Willi syndrome (PWS). Results of clinical, hormonal, and metabolic studies are presented obtained by the observation of 45 children of the prepubertal age suffering from obesity despite the normal body weight. The control group was comprised of 47 children presenting with exogenous constitutional obesity. The percent content of fatty mass in the patients with PWS and obesity was higher than in those with exogenous constitutional obesity (p=0.01) despite a similar degree of obesity. In contrast, the percent content of lean mass in the patients of the former group was significantly smaller (p<0.01). The prevalence of insulin resistance among the children with PWS and obesity was 11.1% compared with 42.5% in those with exogenous constitutional obesity (p=0.013). The blood leptin level, occurrence of dyslipidemia. and percent content of fatty mass in the children with PWS in the absence of obesity were similar to those in the patients with exogenous constitutional obesity.
