Abstract
OBJETIVO: Descrever os níveis de colesterol não-HDL e os fatores correlatos em um grupo de crianças e adolescentes brasileiros. MÉTODOS: De março a outubro de 2002, foram avaliados 2 029 escolares de ambos os sexos com idade entre 7 e 17 anos em Maracaí, Estado de São Paulo. As dosagens bioquímicas foram realizadas com kits de química seca e auto-analisador Vitros 750. O colesterol LDL foi calculado pela fórmula de Friedewald (colesterol LDL = colesterol total - colesterol HDL - triglicérides/5). O colesterol não-HDL foi calculado pela diferença entre o colesterol total e o HDL. RESULTADOS: A correlação entre o colesterol não-HDL e LDL foi de 0,971 (P 0,001). O colesterol não-HDL apresentou melhor correlação em comparação ao LDL com todas as variáveis estudadas: colesterol total, triglicérides, lipoproteínas de alta densidade (HDL-c), lipoproteínas de muito baixa densidade (VLDL-c), índice de massa corporal e cintura abdominal. Os pontos de corte de colesterol não-HDL identificados como sendo indicadores da necessidade de tratamento para dislipidemia em crianças e adolescentes foram: 127,8, 149,2, 181,2 e 213,2 mg/dL. CONCLUSÕES: Os resultados deste estudo contribuem para uma estimativa dos valores de colesterol não-HDL na população de crianças e adolescentes brasileiros e indicam que o colesterol não-HDL é um método confiável e de menor custo para investigar a presença de dislipidemias em crianças e adolescentes.(AU)
 
OBJECTIVE: To describe the levels of non-HDL cholesterol and correlated factors in a group of Brazilian male and female children and adolescents. METHODS: From March to October 2002 we evaluated 2 029 schoolchildren from 7 to 17 years old in the town of Maracaí, São Paulo, Brazil. The biochemical determinations of triglycerides, total cholesterol, and high-density lipoprotein (HDL) cholesterol were carried out using enzymatic reactions and the Vitros 750 analyzer. Low-density lipoprotein (LDL) cholesterol levels were calculated using the Friedewald formula: LDL cholesterol = total cholesterol - HDL cholesterol - (triglycerides/5). Non-HDL cholesterol was calculated by subtracting HDL cholesterol from total cholesterol. RESULTS: The correlation between non-HDL cholesterol levels and LDL cholesterol levels was 0.971 (P 0.001). Non-HDL cholesterol had a stronger correlation than did LDL cholesterol with all the variables under study: total cholesterol, triglycerides, HDL cholesterol, very low-density lipoproteins, body mass index, and waist circumference. The non-HDL cutpoints identified as corresponding to the four cutpoints of LDL cholesterol (110, 130, 160, and 190 mg/dL) indicating the need to treat dyslipidemia in children and adolescents were, respectively: 127.8, 149.2, 181.2, and 213.2 mg/dL. CONCLUSIONS: Our findings contribute toward estimating non-HDL levels in Brazilian children and adolescents. The results also indicate that non-HDL cholesterol is a reliable and less costly method for researching the presence of dyslipidemias in this age group.(AU)
