ABSTRACT

Background and aims We aimed to evaluate the differences in some cardiovascular risk (CVR) factors between adult patients without and with phenylketonuria (PKU) and to explore the correlation between waist circumference (WC) and body mass index (BMI) with the previous variables. Methods This was an observational case–control study that included patients older than 18 years with a diagnosis of classic PKU. The controls were age- and sex-matched individuals. We collected demographic, epidemiological, clinical, and laboratory variables, including WC, BMI, and lipid profile parameters. Results A total of 72 patients (25 controls and 47 cases) were included with a mean age of 36 years, of which 45 (62%) were women. Adult PKU patients showed lower high-density lipoprotein cholesterol (HDL-c) and higher triglyceride (TG) levels than the control group. We found an association between WC and uric acid (B=0.024, P=0.013, 95%CI: 0.005–0.043), TG (B=0.768, P=0.024, 95%CI: 0.107–1.428), and HDL-c (B=−0.254, P=0.026, 95%CI: −0.477 to (−0.032)) levels in PKU patients. However, we did not find any trend between WC and uric acid, TG and HDL-c levels that reached statistical significance (P<0.05) in patients without PKU. Conclusions Waist circumference rather than BMI may better represent the CVR in patients with PKU (AU)


Introducción y objetivos Nuestro objetivo fue evaluar las diferencias en algunos factores de riesgo cardiovascular entre pacientes adultos sin y con fenilcetonuria (FCU) y explorar la correlación del perímetro cintura (PC) e índice de masa corporal (IMC) con las variables previas. Métodos Fue un estudio de casos y controles que incluyó pacientes mayores de 18 años con diagnóstico de FCU clásica. Los controles fueron individuos emparejados por edad y sexo. Se recogieron variables demográficas, epidemiológicas, clínicas y de laboratorio, destacando PC, IMC y parámetros del perfil lipídico. Resultados Se reclutaron 72 pacientes (25 controles y 47 casos) con una edad media de 36 años (62% mujeres). Respecto al grupo control, los pacientes adultos con FCU mostraron niveles más bajos de colesterol de lipoproteínas de alta densidad (HDL-c) y más altos de triglicéridos. En los pacientes con FCU, PC se asoció con los niveles de ácido úrico (B=0,024, P=0,013, 95% CI: 0,005-0,043), triglicéridos (B=0,768, P=0,024, 95% CI: 0,107-1.428) y HDL-c (B=−0,254, P=0,026, 95% CI: −0,477–[−0,032]). Sin embargo, no encontramos ninguna tendencia entre WC y dichas variables que alcanzara significación estadística en los pacientes sin FCU. Aunque observamos una buena correlación entre el IMC y PC en pacientes sin y con FCU, el aumento de PC por unidad de aumento de IMC podría ser mayor en estos últimos. Conclusiones Perímetro de cintura podría representar mejor que IMC el riesgo cardiovascular en pacientes con FCU (AU)

ABSTRACT

Objetivo: comparar las mediciones de perímetro cintura e índice cintura-cadera para determinar la frecuencia del síndrome metabólico en familiares de primer grado de personas con diabetes tipo 1, utilizando diferentes definiciones pediátricas. Métodos: se estudiaron 224 familiares de primer grado de personas con diabetes tipo 1, en edades comprendidas entre los 4 y los 19 años. Se les determinó peso, talla, perímetro cintura y perímetro cadera, tensión arterial, glucemia, triglicéridos y HDL-colesterol. Se aplicaron las definiciones de síndrome metabólico según los criterios de Cook, Ford, la Federación Internacional de Diabetes y del consenso cubano. Se realizó una variante del consenso cubano utilizando: índice de masa corporal e índice cintura-cadera, según tablas cubanas, valores de glucosa ³ 5,6 mmol/L y tensión arterial ³ 90 percentil (tablas cubanas). Se tomaron, de forma independiente, los criterios de HDL-colesterol y triglicéridos. Empleamos el índice cintura-cadera de las tablas cubanas, el perímetro cintura sugerido por la Asociación Latinoamericana de Diabetes y el europeo para las definiciones estudiadas. Para la comparación de las frecuencias del síndrome metabólico, se usó la prueba exacta de Fisher. Resultados: la frecuencia del síndrome metabólico al aplicar la variante del consenso cubano fue de 9,37 por ciento (21/224). Al comparar la variante del consenso cubano con las definiciones de Cook, Ford y la Federación Internacional de Diabetes (que utiliza el perímetro cintura de la Asociación Latinoamericana de Diabetes), se observó diferencia significativa con Cook y la Federación Internacional de Diabetes (4,01 por ciento, p= 0,0360; 1,33 por ciento, p= 0,0002 respectivamente). Al confrontar la presencia del síndrome metabólico de la variante del consenso cubano con Cook (8,48 por ciento; 19/224) y Ford (8,93 por ciento; 20/224), teniendo en cuenta el índice cintura-cadera de las tablas cubanas, podemos detectar frecuencias similares de familiares de primer grado de personas con diabetes tipo 1 con síndrome metabólico. En cambio, encontramos diferencias significativas cuando comparamos las frecuencias del síndrome metabólico de la variante del consenso cubano (p= 0,0019), de Cook (p= 0,0053) y de Ford (p= 0,0032), con la definición sugerida por la Federación Internacional de Diabetes (2,23 pr ciento; 5/224) empleando el índice cintura-cadera. Conclusiones: nuestros datos indican que para el diagnóstico del síndrome metabólico debemos utilizar el índice cintura-cadera y no el perímetro cintura sugerido por la Asociación Latinoamericana de Diabetes, aún sin presentar datos propios del perímetro cintura de la población cubana(AU)


Objective: to compare the measurements of waist circumference and waist-hip circumference to determine the frequency of metabolic syndrome in first degree relatives of persons with type 1diabetes, using different pediatric definitions. Methods: two hundred twenty four first degree relatives of persons with type 1 diabetes were studied in ages from 4 to 10 years. Weight, height, waist-hip circumference, blood pressure, glycemia, triglycerides and HDL-cholesterol were determined. The definitions of metabolic syndrome according to Cook, Ford, International Federation of Diabetes and the Cuban consensus were applied. A variant of Cuban consensus was performed using: body mass index and waist-hip index according the Cuban tables, values of glucose ³ 5,6 mmol/L and blood pressure ³ 90 percentile (Cuban tables). In an independent way, criteria of HDL-cholesterol and triglycerides were taken into account. The waist-hip index of Cuban tables, the waist circumference suggested by the Latin-American and European Association of Diabetes for study definitions were applied. For comparison of frequencies of metabolic syndrome the Fisher exact test was used. Results: the frequency of metabolic syndrome with application of Cuban consensus variant was of 9,37 percent (21/224). Comparing the above variant with the definitions of Cook, Ford and of the International Federation of Diabetes (using the waist circumference of the Latin-American Association of Diabetes, there was a significant difference between Cook and the International Federation of Diabetes (4,01 percent, p= 0,0360; 1,33 percent, p= 0,0002, respectively). Comparing the presence of metabolic syndrome of the Cuban consensus variant with Cook (8,48 percent; 19/224) and Ford (8,93 percent; 20/224) taking into account the waist-hip index of the Cuban tables, it is possible to detect similar frequencies of first degree relatives of persons with type 1 diabetes with metabolic syndrome. On the other hand, we found significant differences comparing the frequencies of metabolic syndrome of the Cuban consensus variant (p= 0,0019), of Cook (p= 0,0053) and of Ford (p= 0,0032) with the definition suggested by the International Federation of Diabetes (2,23 percent; 5/224) using the waist-hip index. Conclusions: our data demonstrate that for the diagnosis of metabolic syndrome we must to use the waist-hip index and not the circumference suggested by the Latin-American Association of Diabetes, still without to present own data of waist-hip circumference of the Cuban population(AU)

ABSTRACT

Current findings suggest that more attention needs to be given to the increase in body mass being achieved by disabled populations in general and individuals with mental retardation in particular, to minimize long-term negative health consequences. Given that physical activity programs have been reported as one of the most effective ways of improving the health of individuals with Down syndrome, it would be of interest facilitate different tools to contribute to their clinical follow-up. Consequently, this study was designed to assess the correlation between anthropometrical parameters and lipid profile in adolescents with Down syndrome. Anthropometric variables such as body mass index, waist circumference and waist-to-hip ratio as well as serum lipids (total cholesterol, high-density-lipoprotein cholesterol, total-choles-terol/high-density-lipoprotein cholesterol and triglycerides) were measured in 21 male adolescents (16.3 ± 1.1 years) with Down syndrome. Anthropometric parameters presented a positive association with serum lipids except for high-density-lipoprotein cholesterol that was negative. It should be emphasized the strongest association of waist-to-hip ratio to total cholesterol/high-density-lipoprotein cholesterol ratio (r = 0.48; p < 0.05). It is concluded waist circumference and waist-to-hip ratio may be highly recommended in clinical practice as appropriate anthropometric predictors of lipid profile in adolescents with Down syndrome. Further studies are required to assess their behavior during physical activity programs as well as to determine more correlations in these individuals.


Si la obesidad como epidemia está alcanzando cotas preocupantes en la población general, la situación es aún más alarmante entre poblaciones con retraso mental en general y síndrome de Down en particular. Afortunadamente, recientes estudios sugieren que los programas de actividad física parecen una buena estrategia para combatirla, especialmente a edades tempranas. Para facilitar el seguimiento clínico de los mismos, diseñamos este trabajo para determinar las correlaciones más significativas entre parámetros antropométricos (índice masa corporal; índice cintura cadera; perímetro cadera) y el perfil lipídico sérico (colesterol total; colesterol-HDL; ratio colesterol total/HDL; triglicéridos) de 21 jóvenes adolescentes (16.3 ± 1.1) con trisomía 21. El coeficiente de correlación de Pearson demostró que las variables antropométricas ensayadas mostraron una correlación positiva con los distintos parámetros lipidicos excepto para colesterol-HDL que fue negativa. En líneas generales el perímetro de la cintura mostró el mejor comportamiento, mientras el índice cintura cadera mostró la mayor fuerza de asociación con la ratio colesterol-total/colesterol-HDL (r = 0.48; p < 0.05). Futuros estudios en los que se confirme la utilidad de estos hallazgos durante la aplicación de programas de actividad física y en los que se evalúen nuevas asociaciones son necesarios para contribuir a un mejor seguimiento y manejo de estos pacientes.
