Background: Substantial evidence indicates that children’s physical fitness levels are markers of their lifestyles and their cardio-metabolic health profile and are predictors of the future risk of chronic diseases such as obesity, cardiometabolic disease, skeletal health and mental health. However, fitness reference values for ethnic children and adolescents have not been published in a Latin-American population. Therefore, the aim of the study was to provide sex- and age-specific physical fitness and anthropometric reference standards among Colombian-Indian schoolchildren. Methods: A sample of 576 participants (319 boys and 257 girls) aged 10 to 17 years old was assessed using the FUPRECOL test battery. Four components of physical fitness were measured: 1) morphological component: height, weight, body mass index (BMI), waist circumference (WC), triceps skinfold, subscapular skinfold, and body fat (%); 2) musculoskeletal component: handgrip and standing long jump test; 3) motor component: speed/agility test (4 × 10 m shuttle run); and 4) cardiorespiratory component: course-navette 20 m, shuttle run test and estimation of maximal oxygen consumption by VO2max indirect. Centile smoothed curves for the 3rd, 10th, 25th, 50th, 75th, 90th and 97th percentiles were calculated using Cole’s LMSmethod. Results: Our results show that weight, height and BMI in each age group were higher in boys than in girls. In each groups, age showed a significant effect for BMI and WC. Boys showed better than girls in cardiorespiratory fitness, lowerand upper-limb strength and speed/agility and girls performed better in low back flexibility. Conclusion: Our results provide for the first time sex- and age-specific physical fitness and anthropometric reference values for Colombian Nasa Indian children and adolescents aged 10–17.9 years.

Etapas de cambio comportamental frente al consumo de sustancias psicoactivas en escolares de 9 a 17 años de Bogotá D.C., Colombia
(Universidad Nacional de Colombia, 2019) Núñez, Óscar; Ramírez Vélez, Robinson; Correa Bautista, Jorge Enrique; Ciencias de la Salud; Osasun Zientziak
Introducción. El consumo de sustancias psicoactivas (SPA) es una problemática que afecta a estudiantes desde edades tempranas. Objetivo. Describir las etapas de cambio de comportamiento frente al consumo de SPA en escolares de Bogotá D.C., Colombia. Materiales y métodos. Estudio transversal en 6 965 escolares de Bogotá D.C. El cambio de comportamiento se evaluó por autoreporte a través de un cuestionario estructurado a partir del Modelo Transteórico en las etapas de precontemplación, contemplación, preparación y acción/mantenimiento. Resultados. 58.4% fueron mujeres con edad promedio de 12.7±2.3 años. Frente al consumo de drogas alucinógenas, 6% de los escolares se ubicaron en la categoría de precontemplación, 44% en contemplación, 30% en preparación y 20% en acción/mantenimiento. Respecto al consumo de alcohol, 5% se encontraban en precontemplación, 36% en contemplación, 12% en preparación y 46% en acción/mantenimiento. El tabaquismo mostró prevalencias de 4% para precontemplación, 33% para contemplación, 12% para preparación y 51% para acción/mantenimiento. Conclusiones. El consumo de SPA es una problemática que se presenta cada vez con mayor frecuencia en población escolar. La mayoría de entrevistados se ubican en etapa de mantenimiento en el consumo de tabaco y alcohol y en la etapa de contemplación de consumo de drogas alucinógenas. Se requieren esfuerzos gubernamentales que fomenten programas preventivos de consumo de SPA en el ámbito escolar.

Normative reference values for the 20 m shuttle-run test in a population-based sample of school-aged youth in Bogota, Colombia: the FUPRECOL study
(Wiley, 2017) Ramírez Vélez, Robinson; Palacios López, Adalberto; Prieto Benavides, Daniel Humberto; Correa Bautista, Jorge Enrique; Izquierdo Redín, Mikel; Alonso Martínez, Alicia; Ciencias de la Salud; Osasun Zientziak
Objectives: Our aim was to determine the normative reference values of cardiorespiratory fitness (CRF) and to establish the proportion of subjects with low CRF suggestive of future cardio‐metabolic risk. Methods: A total of 7244 children and adolescents attending public schools in Bogota, Colombia (55.7% girls; age range of 9–17.9 years) participated in this study. We expressed CRF performance as the nearest stage (minute) completed and the estimated peak oxygen consumption (V˙O2peak). Smoothed percentile curves were calculated. In addition, we present the prevalence of low CRF after applying a correction factor to account for the impact of Bogota's altitude (2625 m over sea level) on CRF assessment, and we calculated the number of participants who fell below health‐related FITNESSGRAM cut‐points for low CRF. Results: Shuttles and V˙O2peak were higher in boys than in girls in all age groups. In boys, there were higher levels of performance with increasing age, with most gains between the ages of 13 and 17. The proportion of subjects with a low CRF, suggestive of future cardio‐metabolic risk (health risk FITNESSGRAM category) was 31.5% (28.2% for boys and 34.1% for girls; X2 P = .001). After applying a 1.11 altitude correction factor, the overall prevalence of low CRF was 11.5% (9.6% for boys and 13.1% for girls; X2 P = .001).
