Comparison of auscultatory and oscillometric BP measurements in children with obesity and their effect on the diagnosis of arterial hypertension / Comparación de la medición de PA auscultatoria y oscilométrica en niños con obesidad y su efecto en el diagnóstico de hipertensión arterial

Abstract: Objective: The level of agreement between two blood pressure (BP) reading methods, auscultatory vs oscillometric, was examined using a mercury sphygmomanometer and an electronic device in children and adolescents with different levels of obesity. The readings were compared to determine their impact on the diagnosis of pre-hypertension/hypertension. Methods: Blood pressure readings were taken in children with obesity (body mass index ≥ 95th percentile) and severe obesity (≥120% 95th percentile). Bland-Altman analysis and Intraclass Correlation Coefficient were used to determine the agreement between measurements. Results: The mercury sphygmomanometer readings were lower than those obtained with the electronic device for both systolic and diastolic BP (P = .01 and P = .001, respectively). The mean systolic and diastolic BP differences between the oscillometric vs first mercury reading were 4.2/10.2 mm Hg, respectively. A large difference was observed between the BP measurement methods. The ICC showed regular to moderate reliability for the systolic BP (.595), but poor for the diastolic BP (.330). Screening using the first of three mercury measurements showed that 10.4% of the children and adolescents had BPs within the pre-hypertension/hypertension range. This was reduced to 5.2% when the mean of three mercury readings was used. Conclusions: Large discrepancies were observed in both the systolic and diastolic BP. These differences are not clinically acceptable as to consider the two instruments interchangeable. The electronic device readings were higher, and they overestimated the diagnosis of hypertension. © 2017 Instituto Nacional de Cardiología Ignacio Chávez. Published by Masson Doyma Mèxico S.A.

Resumen: Objetivo: Para conocer el grado de concordancia entre 2 métodos de medición de presión arterial (PA), auscultatorio vs oscilométrico se utilizó un esfigmomanómetro de mercurio y un dispositivo electrónico en niños y adolescentes con diferentes grados de obesidad. Las lecturas fueron comparadas para conocer su impacto en el diagnóstico de prehipertensión/hipertensión. Método: Se midió la PA a niños con obesidad (percentil 95 del índice masa corporal) y obesidad severa (120% del percentil 95). Utilizamos análisis de Bland-Altman y Coeficiente de Correlación Intraclase (CCI) para conocer acuerdo entre mediciones. Resultados: Las lecturas con esfigmomanómetro de mercurio fueron más bajas que con el electrónico para la PA sistólica y diastólica (p = 0.01 y 0.001, respectivamente). El promedio de las diferencias en sistólica y diastólica entre oscilométrico vs. primera medición con mercurio fue de 4.2/10.2 mm Hg respectivamente. Se observó una gran diferencia de las mediciones entre los métodos de medición de PA. El CCI mostró una confiabilidad regular a moderada para la sistólica (0.595) pero pobre para la diastólica (0.330). El tamizaje con una medición mediante mercurio mostró que el 10.4% de los niños y adolescentes tenían PA en el rango de prehipertensión/hipertensión, pero se redujo a un 5.2% con el promedio de 3 mediciones. Conclusiones: Se observaron grandes discrepancias en la PA sistólica y diastólica. Tales diferencias no son clínicamente aceptables como para considerar equivalentes los 2 instrumentos. Las mediciones realizadas en este estudio con dispositivo electrónico fueron más altas y sobre estimaron el diagnóstico de hipertensión. © 2017 Instituto Nacional de Cardiología Ignacio Chávez.

Association of obesity with chronic disease and musculoskeletal factors / Associação da obesidade com fatores de risco para doenças crônicas e musculoesqueléticas

SummaryIntroduction:overweight and obesity in adolescents are major public health problems with particular interest, because of their potential association with risk factors for development of diseases. The study aimed to determine the prevalence of overweight and obesity in adolescents in southern Portugal and investigate the association with risk factors for development of cardiovascular, respiratory and musculoskeletal diseases.Methods:the sample consisted of 966 adolescents aged 10 to 16 years. The calculation of body mass index (BMI), evaluation of blood glucose, total cholesterol and triglycerides, blood pressure, spirometry and application of low back pain (LBP) questionnaire were performed.Results:178 (18.4%) adolescents were overweight and 52 (5.4%) obese. None of the variables revealed a statistically significant association with overweight and obesity. The presence of high blood pressure was observed in 200 (20.7%) individuals and hypertension in 158 (16.4%) adolescents. Overweight and obese adolescents are 2.3 times more likely to develop signs of pre-hypertension and hypertension. 559 (57.9%) students had restrictive respiratory disorders and 23 (2.4%) had obstructive disorders. Those who were overweight and obese had 0.64 probability of having restrictive respiratory disorders.Conclusion:there was a high prevalence of overweight and obesity in Portuguese adolescents and these showed a statistically significant relationship with the development of pre-hypertension and hypertension, and restrictive respiratory disorders.

ResumoIntrodução:o sobrepeso e a obesidade em adolescentes são atualmente considerados problemas de saúde pública, com interesse decorrente de sua associação a fatores de risco para o desenvolvimento de doenças.Objetivo:determinar a prevalência de sobrepeso e obesidade em adolescentes do sul de Portugal e investigar os fatores associados ao desenvolvimento de doenças cardiovasculares, respiratórias e musculoesqueléticas.Métodos:a amostra foi constituída por 966 adolescentes com idade entre 10 e 16 anos. Foi calculado o índice de massa corporal (IMC) e foram realizadas avaliações de glicemia, colesterol total, triglicerídeos, pressão arterial, espirometria, além da aplicação de um questionário para avaliar a presença de lombalgia.Resultados:cento e setenta e oito (18,4%) adolescentes apresentaram sobrepeso e 52 (5,4%) eram obesos. Nenhuma das variáveis analisadas revelou associação estatisticamente significativa com sobrepeso e obesidade. Duzentos (20,7%) adolescentes apresentaram pressão arterial elevada e 158 (16,4%), hipertensão. Os adolescentes com sobrepeso e obesidade revelaram 2,3 vezes mais chances de desenvolver pré-hipertensão e hipertensão. Quinhentos e cinquenta e nove (57,9%) alunos apresentaram doenças respiratórias restritivas e 23 (2,4%), distúrbios obstrutivos, sendo que os indivíduos com sobrepeso e obesidade apresentaram 0,64 de probabilidade de desenvolver doenças respiratórias restritivas.Conclusão:observou-se uma elevada prevalência de adolescentes portugueses com sobrepeso e obesidade. Essas variáveis demonstraram uma relação estatisticamente significativa com o desenvolvimento de pré-hipertensão e hipertensão arterial e com doenças respiratórias restritivas.

Del adolescente prehipertenso al adulto hipertenso. ¿Es posible pronosticar la conversión? / From the prehypertensive adolescent to the hypertensive adult. Is possible to predict the conversion?

Introducción: Existen gran cantidad de factores de riesgo para el desarrollo de hipertensión arterial. En pleno siglo XXI se imponen formas más inteligentes de investigar, teniendo en cuenta lo que debe constituir un objetivo prioritario, es decir, evitar la conversión de un adolescente en riesgo cardiovascular a un adulto hipertenso. Objetivo: Diseñar un modelo de predicción, para pronosticar la conversión de un adolescente prehipertenso en un adulto hipertenso. Métodos: Se estudió una muestra representativa de 125 adolescentes pertenecientes al proyecto "Pesquisaje Escolar en la Adolescencia de Hipertensión Arterial" (PESESCAD-HTA), con diagnóstico de prehipertensión en el año 2001, que fueron seguidos por ocho años (96 meses), hasta enero de 2009. Resultados: Se obtuvo un modelo predictivo, basado en la regresión logística con un índice de exactitud de 70.4%. Conclusiones: La conversión de un adolescente prehipertenso en un adulto hipertenso, se puede vaticinar con una exactitud adecuada.

Introduction: There are many risk factors for developing hypertension. In the XXI century, smarter ways to investigate are needed, so preventing the turning of an adolescent into a hypertensive adult must be a priority. Objective: The aim of this paper is to predict the risk of hypertension onset in adulthood, from cardiovascular tension and risk stratification since adolescence. Methods: A representative sample of 125 adolescents from the project "Pesquisaje Escolar en la Adolescencia de Hipertensión Arterial" (PESESCAD-HTA) was studied. They were diagnosed with prehypertension in 2001, and were followed for eight years (96 months) until January 2009. Results: Two predictive indexes were obtained. The first, based on the total cardiovascular risk and the second from the multiplication of these risks with an accuracy index for each of 61.6% and 70.4%, respectively. Conclusions: The index based on the multiplication of cardiovascular risk can predict, with adequate accuracy, the turning of a prehypertensive adolescent into hypertensive once he/ she reaches adulthood.

Riesgo cardiovascular en pacientes prehipertensos en un hospital de tercer nivel / Cardiovascular risk in prehypertensive patients in a hospital of third level

Se buscó establecer el impacto de la prehipertensión como causa de eventos cardiovasculares en pacientes del Hospital Universitario San Jorge de Pereira. Se incluyeron pacientes no identificados previamente como hipertensos o que recibieran tratamiento para tal condición y que clasificaran con cifras tensionales sistólicas entre 120 y 139 mmHg y diastólicas entre 80 y 89 mmHg. Del total de prehipertensos se determinó que el 43.4% ingresaron con eventos cardiovasculares, siendo las más prevalentes el evento cerebrovascular y el infarto agudo de miocardio. Se refuerza la indicación de definir la prehipertensión como factor de riesgo a identificar y tratar haciendo énfasis especial en cambios terapéuticos en estilo de vida

An research has been developed with the subject to evaluate the impact of side effects of prehypertension as cardiovascular events on patients of the university hospital San Jorge in the city of Pereira, they include patients non previously identified as hypertensive or who been receiving treatment for that condition and classify with systolic blood pressure between 120 and 139 mmHg and diastolic between 80 and 89 mmHg. From the research where found that 43.4% was ingress with cardiovascular events been more significant stroke and acute coronary syndrome. Those results enhance the indication of defining prehypertension as risk factor to identify and emphasize on therapeutically changes on life style. Within research limitations were found that the time factor was a limitation to increase the samples, which could be important for future research
