ABSTRACT
OBJECTIVE: To evaluate the effectiveness of anthropometric measures and physical activity level in the prediction of metabolic syndrome (MetS) in children. DESIGN: Cross-sectional study with children from public and private schools. Children underwent an anthropometric assessment, blood pressure measurement and biochemical evaluation of serum for determination of TAG, HDL-cholesterol and glucose. Physical activity level was calculated and number of steps per day obtained using a pedometer for seven consecutive days. SETTING: Viçosa, south-eastern Brazil. SUBJECTS: Boys and girls (n 187), mean age 9·90 (SD 0·7) years. RESULTS: Conicity index, sum of four skinfolds, physical activity level and number of steps per day were accurate in predicting MetS in boys. Anthropometric indicators were accurate in predicting MetS for girls, specifically BMI, waist circumference measured at the narrowest point and at the level of the umbilicus, four skinfold thickness measures evaluated separately, the sum of subscapular and triceps skinfold thickness, the sum of four skinfolds and body fat percentage. CONCLUSIONS: The sum of four skinfolds was the most accurate method in predicting MetS in both genders.

O presente estudo avaliou a eficácia do nível de atividade física (NAF), envolvimento em atividade física de moderada a vigorosa intensidade (AFMV) e número de passos/dia para predição dos fatores de risco cardiovasculares (FRCV) em crianças. Foram mensuradas medidas antropométricas, composição corporal, pressão arterial, glicemia, HDL-c e triacilglicerídeos. NAF e envolvimento em AFMV foram obtidos pelo registro de atividade física e número de passos por pedômetro. Participaram 187 crianças com 9,90 ± 0,7 anos de idade. NAF apresentou área sob a curva ROC significativa para predição da obesidade, alto % de gordura corporal e pressão arterial alterada (PAA) nas meninas. NAF foi acurado em predizer obesidade e síndrome metabólica (SM) e AFMV foi acurada em predizer SM e PAA nos meninos. Meninos que atingiram a recomendação de 13000 passos/dia foram protegidos da SM e baixo HDL-c. Atender as recomendações de envolvimento em AFMV e número de passos protegem crianças dos FRCV.
This study evaluated the effectiveness of the physical activity level (PAL), engagement in physical activity of moderate to vigorous intensity (MVPA) and number of steps/day as prediction of cardiovascular risk factors (CVRF) in children. We measured anthropometric parameters, body composition, blood pressure, blood glucose, HDL-c and triglycerides. The PAL and engagement in MVPA were obtained using a questionnaire and computing number steps/days with a pedometer. Participants were 187 children, with a mean age of 9.90 (± 0.7) years. The PAL showed a significant area under the ROC curve as a predictir of obesity, high body fat %, and high blood pressure (HBP) in girls. The PAL accurately predicted obesity and metabolic syndrome (MS), and MVPA accurately predicted MS and HBP in boys. Boys who achieved the recommended 13.000 steps/day were protected from MS and low HDL-c. Achieving the recommendations of engagement in MVPA and number of steps were protection against CVRFfactors in children.
En este estudio se evaluó la efectividad del nivel de actividad física (NAF), la participación en la actividad física de intensidad moderada a vigorosa (ATMV) y el número de pasos / día para la predicción de los factores de riesgo cardiovascular (FRCV) en niños. Medimos las medidas antropométricas, composición corporal, presión arterial, glucemia, colesterol HDL y triglicéridos. NAF y la participación en ATMV se obtuvieron los registros de la actividad física y los pasos podómetro por número. 187 niños participan 9,90 ± 0,7 años. NAF tuvo un área bajo la curva ROC significativa para la predicción de la obesidad, alto% de grasa corporal y la presión arterial enmendada (PAE) en las niñas. NAF fue precisa en la predicción de la obesidad y el síndrome metabólico (SM) y moderada a vigorosa fue precisa en la predicción de SM y PAE en los niños. Los niños que alcanzaron la cantidad recomendada de 13000 pasos /día fueron protegidos de la SM y bajo HDL-c. Alcanzar las recomendaciones de la participación en ATMV y el número de pasos proteger a los niños de los FRCV.

OBJECTIVE: To compare the effectiveness of three waist circumference (WC) measurement sites to predict cardiovascular risk factors and metabolic syndrome (MS) in Brazilian children. METHODS: 187 children (mean age = 9.9 ± 0.7 years) were evaluated for weight, height, WC at three different sites: midpoint between the lower rib and iliac crest (WC1), umbilicus (WC2), and narrowest waist (WC3). Skinfolds (triceps and subscapular) and blood pressure were also measured. Analyses for triglycerides, HDL-C and glucose were carried out in 141 children. RESULTS: For boys, the most accurate predictor of overweight and obesity (from body mass index, BMI) and low HDL-C levels was WC3, and for high percentage of body fat (from skinfolds) was WC1. For girls, WC2 was the most accurate predictor of MS, and hypertriglyceridemia, and for overweight and obesity, high body fat percentage, and low HDL-C levels, WC3 was the best predictor. WC1 was the most accurate in the prediction of high blood pressure. CONCLUSIONS: Each WC measurement site was accurate in predicting cardiovascular risk factors and MS. However, our results indicate that WC3 was the best predictor of cardiovascular risk factors and MS in boys and girls.
