Abstract: En ni os, la obesidad general y visceral se asocian con mayor riesgo cardiometabólico. El aumento en la prevalencia del síndrome metabólico (SM) en ni os y adolescentes empeora el riesgo cardiovascular. Necesitamos contar con nuevos marcadores que permitan predecir el SM en ni os. Objetivo: Comparar índice de masa corporal (zIMC) con razón cintura estatura (RCE) como pre-dictores de SM en ni os chilenos. Método: Estudio transversal en 618 escolares, edad 10.8± 1.9 a os, 51.6% mujeres, 190 eutróficos, 174 sobrepeso, 254 obesos, estrato socioeconómico medio y medio bajo, área urbana de Santiago. Determinamos peso, talla, circunferencia de cintura, presión arterial, perfil lipídico y glicemia. Diagnóstico de SM basado en la presencia de > 3 criterios de Cook. El SM se modeló en función de RCE y z score IMC , con modelos de regresión logística. Se usaron curvas ROC para comparar RCE y zIMC como predictores de SM. Punto de corte según índice de YOUDEN. Resultados: La prevalencia de SM fue 15.37 %. Promedio de z IMC + 1.22± 0.90 y de RCE 0.52±0.07. Punto de corte óptimo para SM: RCE 0.55 (sensibilidad 72%, especificidad 70%)yzIMC: 1.76 (sensibilidad 71%, especificidad 74%). Conclusión: RCE y zIMC predicen igualmente el riesgo cardiometabólico en ni os y adolescentes. Dada la mayor facilidad de calcular RCE, la transforma en mejor herramienta definiendo riesgo en este grupo. El punto de corte > 0.55 sería buen predictor de SM en ni os y adolescentes. Background: Among children both general and visceral obesity are associated with increased cardio-metabolic risk. The increasing prevalence of the metabolic syndrome (MS) in children and adolescents increases cardiovascular risk. Studies of new clinical markers which can easily and accurately predict MS in children and adolescents are needed. Aim: To compare zBMI and waist to height ratio (WHR) as predictors of MS in Chilean children. Method: We performed a crossectional study of 618 schoolchildren, age 11 ± 2 years, 52 % females, 190 eutrophic, 174 overweight, 254 obese, from middle and low social economic strata from the Santiago urban área. We determined weight, height, waist circumference, blood pressure and fasting lipids and glycemia. MS diagnosis was based on the presence of > 3 Cook criteria. MS was modeled in function of WHR and z score BMI, through logistic regression models. ROC curves were used to compare zBMI and WHR as predictors of MS. The cutoff point by YOUDEN índex was used. Results: The prevalence of MS was 15%. Mean zBMI was +1.22 ± 0.90 and WHR 0.52 ± 0.07. Cutoff point for MS were: WHR 0,55 (

Abstract: Introducción: La obesidad y el síndrome metabólico están asociados a un tama o auricular izquierdo (AI) aumentado y mayor riesgo cardiovascular. El strain y strain rate longitudinal determinado por speckle tracking son herramientas novedosas en la evaluación de la función AI. Objetivo: evaluar el strain y strain rate AI en adolescentes obesos y su relación con biomarcadores de riesgo cardiovascular. Métodos: se incluyeron adolescentes consecutivos con un z-índice de masa corporal (z-IMC) > 1 en ritmo sinusal sin otra comorbilidad y un grupo control pareado por edad y sexo. Se registraron las características clínicas y ecocardiográficas con evaluación del strain AI: onda s (LASs), onda a (LASa) y strain rate AI: onda s (LASRs), onda a (LASRa) por speckle tracking. Se midió adiponectina y PCR ultrasensible. Se utilizó t-Student, chi-cuadrado y correlación de Pearson. Resultados: Se incluyeron 15 sujetos por grupo de edad promedio de 13 a os, 47% hombres sin diferencia entre ambos grupos. Los pacientes con sobrepeso presentaron significativamente mayores niveles de PCR us respecto del grupo control, 0,5 ± 0,1 mg/L vs 1,4 ± 0,3, p = 0,04 y menores de LASs (44 ± 1,8 vs 32 ± 1,1%;p<0,01), LASa ( -1,7 ± 0,3 vs -0,7 ± 0,3 1/s; p<0,01), LASRs ( 1,7 ± 0,07 vs 1,3 ± 0,03%; p<0,01), LASRa (-1,8 ± 0,1 vs -1,2 ± 0,08 1/s;p<0,01). En el grupo con sobrepeso se encontró una correlación negativa significativa entre LASs, LASRs y PCR ultrasensible (R: -0,62; p < 0,01 y R: -0,58: p = 0,02 respectivamente). Conclusiones: El strain y strain rate AI se encuentran reducidos en adolescentes obesos y estos parámetros de función AI se correlacionan con un estado inflamatorio aumentado. La importancia clínica de estos hallazgos requieren mayor investigación. Background: Obesity is an emerging problem in children worldwide and a well-known risk factor for atrial fibrillation (AF) in adulthood. There is some evidence that functional and structural changes responsible for the development of AF may arise early in life. Left atrial (LA) strain and strain rate, assessed by speckle tracking, are indices of LA function and correlate with the development of AF. Objective: To evaluate LA strain and strain rate in obese adolescents and their correlation with plasma levels of high sensitive C reactive protein (hs-CRP) and adiponec-tin, two markers of cardiovascular risk. Methods: Fifteen obese adolescents, age 13 ± 0.2 yr, body mass index (BMI)-z-score 1.9 ± 0.16 and 15 lean controls were recruited. All patients underwent transtho-racic echocardiography with evaluation of LA strain and strain

Revista médica de Chile , 2009,
Abstract: Background: The high prevalence of obesity in children favors the appearance of metabolic syndrome (MS), increasing their cardiovascular risk. Aim: To evaluate components of MSin children and to comtate them with surrogate markers of atherosclerosis and subclinical inflammation. Material and methods: We studied 209 children aged 11.5 ± 2 years (50% girls, 30% prepuberal). Fifty percent had normal weight, 18% were overweight, 29% were obese and 3% were undernourished. A fasting blood sample was obtained to measure lipid levels, glucose, insulin, adiponectin and ultrasensitive C-reactive protein (usCRP). Subclinical atherosclerosis was evaluated using flow mediated dilatation of brachial artery (FMD) and carotid intima-media thicknes (IMT). For diagnosis of MS we adapted Cook's criteria. Results: Five percent of all children and 18% ofthose with overweight had MS. Children with more components had significantly higher fasting insulin and Homeostasis Model Assessment (HOMA) values. Clustering of MS components was also associated to higher values of usCRP and non significantly to lower adiponectin levels. We did not find differences in FMD. In obese children there was a tendency towards a higher IMT with clustering of MS components, although not significant. Conclusions: Children with overweight presented a higher risk of a clusteríng of MS components, which was also associated with insulin resistance and increase in ultrasensitive C reactive protein.

Revista médica de Chile , 2011,
Abstract: Background: Plasma insulin and HOMA (homeostasis model assessment) index, used to determine insulin resistance, do not have local standard values for children and adolescents in Chile. Aim: To establish the normal reference intervals for insulin and HOMA in children and adolescents aged 10-15 years, according to sex and puberal maturation. Material and Methods: A cross-sectional study of 2,153 children and adolescents from Puente Alto County was performed, during 2009 and 2010. Anthropometry and self-report of puberal maturation were assessed. Fasting glucose (hexoquinase) and insulin blood levels (chemiluminiscence), were determined and HOMA index was calculated. Percentile distributions of these variables were calculated. Results: The reference group included only subjects with normal body mass index and fasting blood glucose (n = 1,192). Girls had higher insulin and HOMA values than boys (12.5 ± 6.0 and 9.1 ± 4.9 μ /mL (p < 0.01) and 2.7 ± 1.4 and 2.1 ± 1,1 (p < 0.01), respectively). Subjects with Tanner I and IIpuberal stages had lower insulin and HOMA mean values than subjects with Tanner III and IV (9.0 ± 4.3 and 12.5 ± 6.2μ /ml (p < 0.01) and2.0 ± 1 and2.8 ± 1.4 (p < 0.01), respectively). Conclusions: The 90th percentile of insulin and HOMA distributions according to sex and maturation, was selected as the upper cut-off point to identify individuals with insulin resistance. HOMA cutoff point for Tanner I and II boys was 3.2, for Tanner I and II girls was 4.1, for Tanner III and IV boys was 4.2 and for Tanner III and IV girls was 5.0.

Abstract: Background: A cardiovascular risk score for children, that includes traditional risk factors, obesity, sedentary habits and a family history of cardiovascular disease, has been recently proposed by Spanish researchers. Aim: To apply this score in school age children in Santiago de Chile and correlate its results with markers of subclinical atherosclerotic disease. Material and Methods: Retrospective analysis of data obtained from 209 children, aged 11.5 ± 2 years, studied between 2005 and 2006. Weight, height, blood pressure, ultrasound measurement of carotid intimamedia thickness and fow mediated dilatation of brachial artery and ultrasensible C reactive protein (us PCR) were measured. The Spanish cardiovascular risk score was calculated and correlated with ultrasound parameters and C reactive protein. Results: According to the score, 173 children (83%) had a low cardiovascular risk, 28 (13%) an intermediate risk and 8 (4%) a high risk. There was no association between the cardiovascular risk score and carotid intima-media thickness, fow mediated arterial dilatation and us PCR. Conclusions: No significant association was observed between the proposed cardiovascular risk score and early markers of atherosclerotic disease in this group of children.
