RESUMO
Avaliou-se o efeito do retardo de crescimento intra-uterino e de fatores de risco para o retardo de crescimento intra-uterino sobre o perfil lipídico em adolescentes pertencentes ao estudo de coorte de nascimentos de 1982 de Pelotas, Rio Grande do Sul, Brasil. Em 2000, os participantes do sexo masculino foram identificados no alistamento militar; 79 por cento (n = 2.250) foram entrevistados e 2.089 doaram amostra de sangue. No presente estudo, as variáveis dependentes foram o colesterol total e suas frações (VLDL, LDL, HDL), colesterol não-HDL, razão LDL/HDL e triglicerídeos. As exposições estudadas foram o retardo de crescimento intra-uterino, o índice de massa corporal (IMC) materno pré-gestacional e o tabagismo materno durante a gravidez. Após ajuste para fatores de confusão, o colesterol total, LDL e não-HDL foram maiores entre os adolescentes cujo IMC materno pré-gestacional estava no terceiro e quarto quartil. No entanto, tais associações desapareceram após controle para dieta, escolaridade e IMC do adolescente. O retardo de crescimento intra-uterino e o tabagismo materno na gravidez não foram associados com o perfil lipídico aos 18 anos de idade.
ABSTRACT
This study assessed the effects of intrauterine growth restriction and risk factors for intrauterine growth restriction on blood lipids in adolescents from the 1982 birth cohort in Pelotas, Rio Grande do Sul State, Brazil. All male subjects were identified in 2000 when enrolling in the national army; 79 percent (n = 2,250) were interviewed, and 2,089 provided blood samples. The following outcome variables were studied total cholesterol and fractions (VLDL, LDL, and HDL), non-HDL cholesterol, LDL/HDL ratio, and serum triglycerides. The explanatory variables were intrauterine growth restriction, maternal pre-gestational body mass index (BMI), and maternal smoking during pregnancy. After adjusting for confounding variables, total, LDL, and non-HDL cholesterol levels were slightly and significantly higher among adolescents whose mothers were in the 3rd and 4th quartiles of pre-gestational BMI. However, these associations disappeared after adjusting for the adolescent's diet, schooling, and BMI. Other associations were not significant (p > 0.05).
