    PURPOSE: There is increasing evidence that cardiorespiratory fitness (CRF) is an important health marker in youth. CRF values for children and adolescents from different countries have been published, but there is a scarcity of reference values for Latin American children and adolescents using recommended CRF estimation field tests such as the 20-m shuttle-run test as evidence of CRF in Colombian schoolchildren. In addition to presenting normative reference values, we also aim to establish the proportion of subjects whose aerobic capacity is indicative of future cardiovascular risk. METHODS: A total of 7244 children and adolescents (55.7% girls, with a sample age range of 9-17.9 years) completed the 20 m shuttle-run test (median age, in years = 12.8 (SD 2.3); 25th-75th percentile: 11.0-15.0. We expressed performance as the number of shuttle-runs completed and the estimated peak oxygen consumption (VO2peak). Smoothed percentile curves and tables for the 3rd, 10th, 25th, 50th, 75th, 90th and 97th percentiles were calculated using Cole’s LMS method. In addition, we calculated the number of participants who fell below proposed cut-offs for low CRF based on either completed shuttle-runs or by VO2peak. RESULTS: In general CRF levels increased with age. Among boys CRF, where higher between the ages of 14 and 17 and in girls between the ages of 12 and 14, but this increase was more modest. Shuttles and VO2peak were higher in boys than in girls in all age-specific groups. The proportion of subjects with a CRF indicative of future cardiovascular risk was 11.5%. By sex, 9.65% of boys and 13.1% of girls (X2 p < .001) displayed an unhealthy aerobic capacity in this study. CONCLUSIONS: Our results provide reference standards for sex- and age-specific twenty- meter shuttle-run test scores and VO2peak values in Colombian schoolchildren aged 9-17.9 years for the first time. These values are particularly important in public health and educational settings, and future research should establish a cut-off value for test performance that can predict present or future ill health.

    Low cardiorespiratory fitness is associated with elevated adiposity markers among children and adolescents from bogotá, colombia. the fuprecol study: 852 Board #168 June 1, 330 PM - 500 PM

    PURPOSE: Low cardiorespiratory fitness (CRF) is independent risk factors for future cardio-metabolic disease in children and adolescents. The fitness versus fatness relationship has not been studied in a population-based sample in Latin America. The aim of this study was to examine the relationship between the CRF with adiposity markers among children and adolescents from Bogotá, Colombia. METHODS: Cross-sectional study in 7,960 healthy Colombian youth (boys n=3,462 and girls n=4,494) residents in the metropolitan area of the District of Bogotá, Colombia (2480msnm). CRF was assessed with the 20-meter shuttle run test. Waist circumference (WC), body fat percentage-BF%, ? skinfolds thicknesses (triceps + subscapular), body mass index (BMI) and waist-to-height ratio (WHtR) were used as indicators of adiposity. RESULTS: After adjusting for sex, age and sexual maturation, significant inverse relationships were observed between CRF and BMI (r = -0.360), BF% (r = -0.387), ? skinfolds (r = -0.417), WC (r = - 0.258) and WHtR (r = -0.201), p < .001. CONCLUSIONS: Our results show that high aerobic capacity is associated with less adiposity markers. Increasing CRF should be targets in youth primordial prevention strategies of future cardio-metabolic disease in adulthood.

    Profile of nutritional status of children and adolescents from bogota, Colombia the fuprecol study: 3717 Board #156 June 4, 800 AM - 930 AM
    (2016-05) Benavides Rodríguez, Lorena; Palacios-López, Adalberto; Ojeda-Pardo, Monica Liliana; Peña, Jhonatan C.; Correa Bautista, Jorge Enrique; Ramírez-Vélez, Robinson
    PURPOSE: This study aimed to analize the nutritional status among Colombian children and adolescents and to determine the relationship between the nutritional status according to the body mass index (BMI) and the waist circumference (WC). METHODS: A cross-sectional study was conducted in 6,383 children and adolescents with age of 9 to 17.9 years old from Bogota, Colombia. Participants completed the “Krece Plus” questionnaire validated by the “enKid study” as an indicator of the nutritional level with the following categories: high (test ? 9), medium (test 6-8) and low (test ? 5). Other measures were: weight, height, WC and BMI as markers of the nutritional status. RESULTS: Overall, 57.9% of the participants were girls (mean age 12.7±2.3 years old). The nutritional status was low without large differences by sex and decreasing by age. In all categories of BMI, over 50% of boys and girls follow lower-quality diet, shown progressively worse with advancing age. In both sexes, trends were observed between low nutritional level with the development of overweight. Also, WC was associated with a lower score in the “Krece Plus” in both sexes.

    Reference values for standing broad jump in colombian schoolchildren the fuprecol study: 2767 board #290 June 3, 930 AM - 1100 AM

    PURPOSE: Muscular power refers to the ability to perform high-intensity exercise for a fraction of a second to several minutes. Therefore, the purpose of this study was to develop age-and sex-specific normative reference values for lower-body muscular power assessed by the standing broad jump (SBJ) in Colombian schoolchildren. METHODS: A total of 7244 children and adolescents (55.7% girls, with a sample age range of 9-17.9 years) completed the SBJ test (median age, in years = 12.8 (SD 2.3); 25th-75th percentile: 11.0-15.0. The distance between takeoff and the heel of the closest foot at landing was recorded in centimeters, and participants were allowed one more try if they landed with their hands behind their feet. Smoothed percentile curves and tables for the 3rd, 10th, 25th, 50th, 75th, 90th and 97th percentiles were calculated using Cole’s LMS method. RESULTS: The one-way ANOVA tests showed that maximum SBJ (cm) was higher in boys than in girls (p<0.01). Post hoc analyses within sexes showed yearly increases in SBJ scores in all ages. In boys, the maximum SBJ scores 50th percentile ranged from 110 to 165 cm. In girls, the 50th percentile ranged from SBJ scores was 96 to 120. Both linear and quadratic age terms were statistically significant predictors of SBJ trends across age. CONCLUSIONS: Our results provide reference standards for sex- and age-specific SBJ scores in Colombian schoolchildren aged 9-17.9 years for the first time. The proposed reference values can be used to interpret SBJ scores in Colombian schoolchildren.
