Hipercolesterolemia em jovens adolescentes

Hipercolesterolemia em jovens adolescentes

Abstract

O colesterol encontra-se em todas as células do organismo humano. Se, por um lado, é vital, por exemplo, para a construção de novas células, por outro, pode acumular-se no nosso organismo, levando à deposição de gordura na parede das artérias. Encontra-se bem fundamentada a relação entre o aumento drástico de mortes por doença cardiovascular, nos países desenvolvidos, e o elevado nível de colesterol que se verifica em parte substancial da sua população. Sendo uma substância lipídica, necessita de transportadores específicos para circular no plasma, as lipoproteínas. Estas partículas designam-se de acordo com a sua densidade. As duas mais importantes são as lipoproteínas de alta densidade (HDL) e as lipoproteínas de baixa densidade (LDL). As primeiras têm como principal função remover o excesso de colesterol para o fígado. Pelo contrário, as segundas transportam o colesterol do fígado para as células. Este trabalho visa estudar a problemática da hipercolesterolemia, na população infantil e adolescente. Neste segmento populacional, esta condição assume especial importância, sobretudo quando se verifica a conjugação de altos níveis de LDL colesterol com baixos níveis de HDL colesterol, pelas consequências na saúde a longo prazo. O aumento muito significativo da hipercolesterolemia relaciona-se intimamente com o estilo de vida actual, que contempla diversos factores de risco, a serem analisados com detalhe ao longo do trabalho. Pela análise de uma grande variedade de dados estatísticos, procurou caracterizar-se cada um destes factores, no sentido de avaliar a sua efectiva contribuição para a prevalência da hipercolesterolemia, em crianças e jovens, e verificar a existência de possíveis correlações entre eles, que pudessem contribuir de forma decisiva para o aumento do risco. Cholesterol is found in all cells of the human organism. If, on the one hand, it is vital, for example, to build new cells, on the other hand, it can also accumulate in the body, leading to fat deposition in artery walls. There is a well-substantiated relationship between the dramatic increase in deaths caused by cardiovascular disease in developed countries and the high level of cholesterol occurring in a substantial share of its population. As a lipid substance, it requires specific transporters making it possible to circulate in plasma, designated lipoproteins. These particles are classified according to their density. The two most important are the high-density lipoproteins (HDL) and the low-density lipoproteins (LDL). The former are mainly responsible for removing the excess of cholesterol to the liver. On the contrary, the latter carry cholesterol from the liver to the cells. This work aims to study the problem of hypercholesterolemia in children and adolescents. In this population segment, this condition is of extraordinary importance, especially when there is a combination of high levels of LDL cholesterol with low levels of HDL cholesterol, because of the long term health consequences. The impressive increase of hypercholesterolemia is closely linked with the current lifestyle, which includes various risk factors, to be analyzed in detail throughout the paper. The analysis of a wide variety of statistical data seeked to characterize each of these factors, in order to assess their actual contribution to the prevalence of hypercholesterolemia, in children and young people, and search for possible correlations between them, which could decisively contribute to increase the risk.
