Objective: the aim was to establish reference standardsfor waist/hip ratio among Colombia children andadolescent aged 9 to 17.9 years who participated in “TheFUPRECOL Study”.Methods: cross-sectional study. A sample of 3 005children and 2 916 adolescents healthy Colombian youth(boys n = 2 542 and girls n = 3 384) participated in the study.Height, weight, waist circumference, hip circumferenceand sexual maturation status were measured. Referencecurves were fitted with the LMS method (L [curve Box–Cox], M [curve median] and S [curve coefficient ofvariation]), for boys and girls, stratified by age group,and to compare them to international references.Results: in all ages, the waist/hip ratio was higherin boys than in girls. Subjects whose waist/hip ratiowas above the 90th percentile of the standard normaldistribution were considered to have high cardiovascularrisk (boys range 0.87 to 0.93 and girls range 0.85 to0.89). Overall, our waist/hip ratio values were lower thanEurope, Asia and Africa values and similar to those ofsome Latin American references.Conclusions: values reference charts for waist/hip ratiovalues specific for age and sex, obtained from children andadolescents from Bogota, Colombia, are provided. Theymay be used regionally, both for nutritional assessmentand to predict cardiovascular risks in early age.
