    Objective: To determine the association between consumption of snacks and sweetened beverages and risk of overweight among children. Design: Secondary analysis of the Young Lives cohort study in Peru. Setting: Twenty sentinel sites from a total of 1818 districts available in Peru. Subjects: Children in the younger cohort of the Young Lives study in Peru, specifically those included in the third (2009) and the fourth (2013) rounds. Results: A total of 1813 children were evaluated at baseline; 49•2 % girls and mean age 8•0 (SD 0•3) years. At baseline, 3•3 (95 % CI 2•5, 4•2) % reported daily sweetened beverage consumption, while this proportion was 3•9 (95 % CI 3•1, 4•9) % for snacks. Baseline prevalence of overweight was 22•0 (95 % CI 20•1, 23•9) %. Only 1414 children were followed for 4•0 (SD 0•1) years, with an overweight incidence of 3•6 (95 % CI 3•1, 4•1) per 100 person-years. In multivariable analysis, children who consumed sweetened beverages and snacks daily had an average weight increase of 2•29 (95 % CI 0•62, 3•96) and 2•04 (95 % CI 0•48, 3•60) kg more, respectively, than those who never consumed these products, in approximately 4 years of follow-up. Moreover, there was evidence of an association between daily consumption of sweetened beverages and risk of overweight (relative risk=2•12; 95 % CI 1•05, 4•28). Conclusions: Daily consumption of sweetened beverages and snacks was associated with increased weight gain v. never consuming these products; and in the case of sweetened beverages, with higher risk of developing overweight.

    Objective: Evaluate condylar morphology in patients with skeletal pattern class II and class III. Materials and methods: CT scans of 124 patients (18 to 30 years) were evaluated. They were divided into 2 groups according to the skeletal pattern (class II and class III). Skeletal patterns were classified by measuring the ANB angle of each patient. The antero-posterior diameter of the right and left mandibular condyle was assessed from a sagittal view by locating points A and P to obtain a distance in mm. On the other hand, the coronal plane allowed to evaluate the medial-lateral diameter where the points M and L were drawn to obtain in the same way a measurement in mm. Results: Significant differences were found in the mid-lateral diameters between class III and class II.The measures were higher in those class III. For class II, the right mid-lateral diameter presents an average of 17.94 ± 2.68 and the left one of 17.67 ± 2.44, while for class III the average found for the right condyle was 19.16 ± 2.75 and the left one 19.16 ± 2.54. Conclusion: It was found that the medial-lateral diameter of patients with skeletal class III is higher than those of class II.
