Sono e fatores de risco cardiometabólicos em crianças e adolescentes com excesso de peso

Abstract

Obesity in childhood and adolescence is a risk factor for various morbidities among these cardiovascular diseases and diabetes mellitus type 2. Epidemiological studies show that short sleep duration and overweight in children and adolescents tee m joint effect on cardiometabolic risk factors and exacerbated the tendency for excessive daytime sleepiness. OBJECTIVE: To evaluate the duration of sleep and excessive daytime sleepiness and their relationship with cardiometabolic risk factors in children and adolescents are overweight. METHODS: Cross-sectional study conducted from June 2011 to March 2012 on public service reference assisting children and adolescents who are overweight in Campina Grande / PB. The sample consisted of 140 children and adolescents who are overweight at age 05-18 years. We performed anthropometry, blood pressure checked, applied and sociodemographic questionnaire about sleep habits, applied the Epworth Sleepiness Scale and conducted laboratory tests (lipid profile, glucose, insulin, HOMA-IR, glycated hemoglobin, C-reactive protein ultra and leptin-sensitive). The duration of sleep was classified as: short (<8 hours), medium (8 &#8804; duration <11 hours) and long (&#8805; 11 hours). Data were analyzed in SPSS version 17, we used the chi -square test for trend, the variance test and Pearson correlation test, adopting a significance level of 5%. RESULTS: Mean sleep duration was 8.54 hours (± 1.74, 5.0 to 11.5). The short duration was associated with higher mean age (p = 0.002), BMI (p = 0.000), waist circumference (WC) (p = 0.000), insulin (p = 0.021), HOMA-IR (p = 0.012) and leptin (p = 0.018). The long duration was associated with mean BMI (p = 0.006), CA (p = 0.024) and total cholesterol (p = 0.036). The prevalence of excessive daytime sleepi ness was 19.3%, not being observed association with cardiometabolic risk factors. CONCLUSION: Short sleep duration was associated with multiple cardiometabolic risk factors and the prevalence of excessive daytime sleepiness was relevant, reaffirming the need to assess sleep in this population. Early identification of modifiable risk factors for obesity, therefore, avoids substantial cardiometabolic morbidity, especially in children and adolescents are overweight.
