The aim of the study was to evaluate the prevalence of excessive daytime sleepiness and its associationwith cardiometabolic risk factors. Method: Cross-sectional study carried out in a public service, which is reference service for overweight children and adolescents in the period from June 2011 to March 2013in Campina Grande / PB. The sample consisted of 140 children and adolescents aged from five to 18 years. Anthropometry and blood pressure measures were performed and a questionnaire on sleep habits and Epworth Sleepiness Scale were applied. Laboratory tests were also conducted (lipid profile, blood glucose levels, insulin, HOMA-IR, glycatedhemoglobin, ultrasensitive C-reactive protein and leptin). Data wereanalyzed using SPSS software (v.17), through the chi-square test, ANOVA and Pearson's correlation, with significance level of 5%. Results:the prevalence of excessive daytime sleepiness was 19.3% and it was higher among girls. In those with excessive daytime sleepiness was observed the highest percentage change in LDL levels, HbA1c and CRPu, butwithout statistical significance. Conclusions: the presence of sleepiness were prevalent in this sample, and those with this condition showed less favorable metabolic results.
