Overweight and obesity among adolescents, as well as changes in the metabolism of glucose and triglycerides, have reached epidemic proportions in most industrialized countries. Changes in nutritional status have been followed by increased consumption of sugar beverages. Some systematic reviews have identified that the consumption of sugar beverages is associated with weight gain among general population, including adolescents. The effect of these beverages seems to influence not only the occurrence of overweight and obesity, but also in other diseases associated to obesity, as hypertension, hepatic steatosis and occurrence of type 2 diabetes. A reasonable effect of the increase in the sugar drink consumption would be the alteration in triglicérides and the glicêmico control, but two studies you only part, in American adolescents, had been found and both had concluded for the deleterious effect of the consumption of such drinks in these metabolic parameters.The present thesis had as objective to carry through a bibliographical revision on sugar drink consumption and metabolic alterations in adolescents. E to evaluate this association in pertaining to school a probabilist sample of the city of Niterói, Rio de Janeiro, with 610 adolescents of 12 the 19 years. In the revision only two articles had been rescued. In the first one one met that for each additional portion of sugar drinks consumed per day, it had increase of 7% in the values of HOMA-IR, increase of 2,25mg/dL in the concentrations of triglicérides, reduction of 0,73mg/dL of HDL-C in the girls and reduction of 0,35mg/dL of HDL-C in the boys (p-valor<0,05). In as, insulin was observed a trend of sugar drinks to explain 2.4% of the variance in AIR - Acute response (β=-0,219, p-valor=0,07), without difference between the sexos. With the adolescents of the city of Niterói, girls reported, on average, a lower sugar beverage consumption than boys (222 vs. 262mL), and the prevalence of daily consumption was grether than 75% for both sexes. Boys who drink sugar beverages presented higher energy and carbohydrates intakes than those who did not drink sweetened beverages (2.183 vs. 2.787kcal and 286.3 vs. 376.6 g, respectively). In the final regression model the consumption of sweetened beverages showed a positive association only for triglycerides in boys, after adjusting for age, BMI, energy and carbohydrate inatke, (&#61538;= 0.06, p = 0.04). In conclusion, both the literature reviewed and the data analysis from adolescents of Niterói revealed a positive association between sugar beverage consumption and metabolic changes
