El granulo de caucho reciclado (GCR), se genera a partir del procesamiento de las llantas usadas o de desecho, se realiza este tipo de aprovechamiento ya que dicho residuo tiene diferentes aplicaciones como: construcción de vías, diseño de baldosas para parques y jardines, impermeabilización de canchas sintéticas, entre otros. Actualmente en diferentes ciudades del país, se han creado empresas que se encargan de procesar las llantas usadas en granulo de caucho reciclado (GCR), sin embargo, en la ciudad de Bogotá aún no cuenta con un mercado potencial que permita establecer una dinámica creciente en relación a la demanda de aquel residuo para que se convierta en materia prima para distintas utilidades. Existe desconocimiento de los impactos positivos para el medio ambiente, mayor difusión de los efectos que conduce la empleabilidad del granulo de caucho reciclado en diferentes campos como: obras civiles, infraestructura vial, mezcla para asfáltica, etc.

Background: Increased visceral or abdominal adipose tissue in children and adults is strongly associated with metabolic and a variety of chronic diseases. Aim: To study the association between visceral or external body measurements of adiposity with blood lipids, glucose and insulin levels, in obese female adolescents. Material and methods: In a cross-sectional study, 47 obese female adolescents (body mass index (BMI) >95th percentile) aged 10 to 15 years, were analyzed. Weight, height, BMI, Tanner pubertal stages, skinfold thickness, waist circumference, waist-to-hip ratio, fasting and 120 min post prandial blood glucose, serum insulin, and lipid profile were studied. Visceral fat was assessed by computed tomography at the L4-L5 level, measuring the fat area or the length of a straight drawn line between the spine and the internal border of the rectus abdominus muscle. Results: No association between lipid profile and BMI or external body measurements (skinfold thickness, waist circumference, waist-to-hip ratio) was observed. Total serum cholesterol >170 mg/dL was positively associated with the straight line over 63 mm (a cut-off obtained by ROC analysis (RR 2.64; 1.15-6.08). This association was statistically significant in girls in Tanner I + II (n =21; Fisher, p 170 mg/dL) was also positively associated with a serum insulin >17 uU/mL in the Tanner I + II group (Fisher p170 mg/dL) was associated with visceral fat (evaluated through the straight line spina-rectus abdominus muscle), and also with a serum insulin >17 uU/ml in those teenagers with Tanner I or II pubertal stages
