          Abstract

          Se estudió el perfil de lípidos y el patrón de consumo de una población de 50 adultos chinos inmigrantes residentes en San José, Costa Rica durante el año de 1999. Los resultados indican que el 35% de éstos(as) inmigrantes presenta niveles altos de CT ( > o = 5,16 mmol/L) y el 51% concentraciones elevadas de LDL-C ( > o = 2,84 mmol/L). Asimismo, en el 36% de la muestra se evidenciaron niveles elevados de Tg (> 1,69 mmol/L) y solamente en el 15% concentraciones bajas de HDL-C (<= 0,90 mmol/L). La proporción de hombres con concentraciones elevadas de CT, LDL-C y Tg y niveles bajos de HDL-C fue mayor que la de mujeres; aunque esta diferencia no llegó a ser significativa. El 41% de la población estudiada presentó valores mayores de 4,5 para el Índice de Castelli (CT/HDL-C). En general, cerca del 80% de los (as) chinos (as) inmigrantes consumen vegetales 5-6 veces/semana y alrededor del 50% consumen frutas con esa misma frecuencia. Un alto porcentaje de los inmigrantes consumen alimentos fuente de proteína animal más de 3 veces/semana y alrededor del 23% consumen frecuentemente comidas rápidas y snacks. Nuestros datos sugieren que los inmigrantes chinos mantienen algunas características de su cultura alimentaria. Sin embargo, han modificado su patrón alimentario convirtiéndolo en uno más aterogénico. Es importante que los nutricionistas y otros profesionales del área de la salud, evalúen con mayor detalle los factores asociados al cambio del patrón alimentario en inmigrantes, con el propósito de evitar un aumento en las tasas de morbi-mortalidad por enfermedad coronaria en ese grupo de población.

          Lipid profile of Chinese immigrants living in Costa Rica. The lipid profile and food pattern of 50 Chinese immigrants living in San José, Costa Rica were studied during 1999. The results showed that 35% of the immigrants had high levels of total cholesterol ( > or = 5,16 mmol/L) and 51% had high concentrations of LDL-Cholesterol ( > or = 2,84 mmol/L). Moreover, 36% of them had high levels of triglycerides (> 1,69 mmol/L) and only the 15% had low concentrations of HDL-cholesterol (<= 0,90 mmol/L). The ratio of men with high levels of total cholesterol, LDL-cholesterol and triglycerides and low levels of HDL-cholesterol was larger that the one in women; although this difference was not significant. 41% of the studied population presented Castelli’s Indexes (TC/HDL-C) above 4,5. In general, around 80% of the Chinese immigrants consume vegetables 5-6 times/week and 50% consume fruits with the same frequency. A high percentage of the immigrants eat food with animal protein more than 3 times/week and around 23% eat frequently snacks and fast foods. Our data suggest that the Chinese immigrants still keep some characteristics of their nutritional culture. Nevertheless, they have changed their food pattern to a more atherogenic one. It’s important that nutritionists and other health professionals evaluate in detail the factors associated with the change in the food pattern of the immigrants, in order to avoid an increase in the rates of morbi-mortality of coronary disease in this group of population.

            Endothelial dysfunction is associated with cholesterol levels in the high normal range in humans.

            The purpose of this study was to test the hypothesis that cholesterol levels in the high normal range are associated with impaired endothelium-dependent vasodilation. We studied leg blood flow (LBF) responses to graded intrafemoral artery infusions of the endothelium-dependent vasodilator methacholine chloride (MCh) or the endothelium-independent vasodilator sodium nitroprusside (SNP) in normal volunteers exhibiting a wide range of total cholesterol levels within the normal range (<75th percentile). LBF increased in a dose-dependent fashion in response to the femoral artery infusions of MCh and SNP (P<.001). LBF responses to MCh were significantly blunted (P<.001) in subjects with high normal cholesterol (195+/-6 mg/dL, n=13) compared with subjects with low normal cholesterol (146+/-5 mg/dL, n=20). Maximal endothelium-dependent vasodilation in the high normal group was decreased by nearly 50% compared with the low normal group (146+/-13% versus 268+/-34%, P<.01). There was a negative correlation between total cholesterol levels and maximal endothelium-dependent vasodilation (total cholesterol, r=-.41, P<.02; LDL cholesterol, r=-.42, P<.02). On the other hand, LBF responses to the endothelium-independent vasodilator SNP did not differ between groups. These data suggest that an inverse and continuous relationship exists between the prevailing cholesterol level and endothelium-dependent vasodilation. Moreover, cholesterol levels even in the normal range may be associated with endothelial dysfunction, thus potentially contributing to the increased risk of macrovascular disease conferred by cholesterol elevations.
