Standardisation of the waist circumference (WC) for each range of body mass index (BMI) in adult outpatients attended to in Endocrinology and Nutrition departments. Nutr Hosp; 25(2):262-90212-1611CODEN NUHOEQ S.V.R. 318http://hdl.handle.net/10668/603En este estudio hemos buscado el rango de circunferencia de cintura (WC) para cada grado de índice de masa corporal (BMI), que sirva para estudios que determinen riesgos de salud. Estudiamos 2.932 pacientes (39,6% varones y 60,4% mujeres, entre 18 y 96 años) del mismo grupo étnico que consecutivamente asistieron a consultas externas de nuestras clínicas entre 2000 and 2004. El BMI correlacionó linealmente con la WC (cc:0,85; p < 0,001). Eran mayores los varones, los obesos y los diabéticos. El BMI era mayor en mujeres y la WC en varones. Las mujeres tenían mayor WC si eran diabéticas (p < 0,01), igualando a los hombres. Los varones tenían mayor WC si eran diabéticos (p < 0,001). La circunferencia de riesgo (varones > = 102 cm y mujeres > = 88 cm) la presentaban el 94,3% de los obesos, el 32,3% de los pacientes con sobrepeso y el 3,8% de pacientes con BMI <25, el 84,3% de diabéticos y el 72,6% de pacientes sin diabetes. Elaboramos una estandarización gráfica de WC en relación con BMI y calculamos los precentiles 10, 25, 50, 75 y 90, agrupados en rangos de 2 kg/m2 de BMI. Como el número de diabeticos es menor, los agrupamos en rangos de 4 kg/m2. En conclusión presentamos una estandarización de la WC de pacientes atendidos en nuestra consulta de endocrinología y nutrición distribuidos en percentiles como herramienta utilizable clínicamente para definir rangos de WC para cada valor de BMI.By this study we seek the expectable range of waist circumference (WC) for every degree of body mass index (BMI), which will serve to studies targeting ascertaining the health risk. We studied 2,932 patients (39.6% men and 60.4% women, between 18 and 96 years ) of the same ethnic group who consecutively attended outpatient departments of our clinics between 2000 and 2004. BMI correlated linearly with the WC (cc: 0.85; p < 0.001). The men, the obese, and diabetics were older (p < 0.001). BMI was greater in women and WC in men. The women had a greater WC if they had diabetes (p < 0.01), being equal to diabetic males. The men had greater WC when they had diabetes (p < 0.001). Waist at risk was detected (men > or = 102 cm and women > or = 88 cm) in 94.3% of the obese, in 32.3% of overweight patients, in 3.8% of patients with BMI < 25, in 84.3% of diabetics, and in 72.6% of patients without diabetes. We made graphic standardisation of WC with regard to BMI, and we calculated the percentiles 10, 25, 50, 75 and 90, grouping in ranges of 2 kg/m(2) of BMI. The diabetic patients are grouped in ranges of 4 kg/m(2). As conclusion we present a standardisation of the WC measurement of patients attended to in our Endocrinology and Nutrition practices distributed in percentiles as a clinically usable tool to define the ranges of WC for every BMI value.esObesityDiabetes mellitusWaist circumferenceBody mass indexStandardizationObesidadDiabetes mellitusCircunferencia de cinturaÍndice de Masa CorporalEstandarizaciónAdultoAncianoAnciano de 80 o más AñosEndocrinologíaFemeninoDepartamentos de HospitalesHumanosMasculinoMediana EdadCiencias NutricionalesPacientes AmbulatoriosEstándares de ReferenciaAdulto JovenMedical Subject Headings::Named Groups::Persons::Age Groups::AdultMedical Subject Headings::Named Groups::Persons::Age Groups::Adult::AgedMedical Subject Headings::Named Groups::Persons::Age Groups::Adult::Aged::Aged, 80 and overMedical Subject Headings::Health Care::Environment and Public Health::Public Health::Epidemiologic Measurements::Biometry::Anthropometry::Body Mass IndexMedical Subject Headings::Disciplines and Occupations::Health Occupations::Medicine::Internal Medicine::EndocrinologyMedical Subject Headings::Check Tags::FemaleMedical Subject Headings::Health Care::Health Care Facilities, Manpower, and Services::Health Facilities::Hospital Administration::Hospital DepartmentsMedical Subject Headings::Organisms::Eukaryota::Animals::Chordata::Vertebrates::Mammals::Primates::Haplorhini::Catarrhini::Hominidae::HumansMedical Subject Headings::Check Tags::MaleMedical Subject Headings::Named Groups::Persons::Age Groups::Adult::Middle AgedMedical Subject Headings::Disciplines and Occupations::Health Occupations::Nutritional SciencesMedical Subject Headings::Named Groups::Persons::Patients::OutpatientsMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Weights and Measures::Reference StandardsMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Physical Examination::Body Constitution::Body Weights and Measures::Body Size::Waist CircumferenceMedical Subject Headings::Named Groups::Persons::Age Groups::Adult::Young AdultMedical Subject Headings::Named Groups::Persons::Age Groups::Adolescentresearch article20449536open access10.3305/nh.2010.25.2.45201699-5198
