These risk factors can induce changes in the arteries such as an increase in the carotid intima-media thickness (cIMT), which contributes to the early development of atherosclerosis. OBJECTIVE: To determine whether NAFLD is associated with an atherogenic lipid profile, inflamma- tory markers, or cIMT in obese adolescents and to compare the effects of therapeutic lifestyle changes in NAFLD and non-NAFLD groups. METHODS: A total of 79 obese adolescents were divided into two groups: 33 NAFLD and 46 non- NAFLD. They were submitted to an interdisciplinary therapy involving diet exercise and psychological support during the course of 1 year. The cIMT and estimates of fat mass (liver, intra-abdominal, and sub- cutaneous) were determined ultrasonographically. Body composition, glucose, lipid profile, and adipokines were analyzed before and after the therapy. RESULTS: At baseline, only in the NAFLD group was the homeostasis model assessment of insulin resistance positively correlated with cIMT and triglyceride/high-density lipoprotein cholesterol ratio. Therapy was associated with an increase in adiponectin concentrations and reduced visceral fat, cIMT, leptin, and plasminogen activator inhibitor-1 concentrations, as well as the ratios of total cholesterol/ * Corresponding authors.
