Previous issue date: 2008-01-01 / Sem bolsa / Este estudo avaliou os efeitos do retardo de crescimento intra-uterino (RCIU) e de variáveis pré-natais relacionadas ao crescimento fetal sobre o perfil lipídico em adolescentes. Em 1982, todos os nascimentos hospitalares ocorridos em Pelotas foram identificados e esta população tem sido acompanhada inúmeras vezes. Em 2000, os participantes masculinos da coorte foram identificados no alistamento militar; 79% (n=2250) foram entrevistados e 2089 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 RCIU, o índice de massa corporal (IMC) materno pré-gestacional e o tabagismo materno na gravidez. Após ajuste para fatores de confusão, o colesterol total e LDL foram maiores entre os adolescentes cujo IMC materno pré-gestacional estava no terceiro e quarto quartil. No entanto, estas associações desapareceram após controle para dieta, escolaridade e IMC do adolescente. Associação similar foi observada para o colesterol não-HDL. O RCIU e o tabagismo materno na gravidez não foram associados com o perfil lipídico aos 18 anos de idade. Um IMC materno pré-gestacional elevado parece influenciar o perfil lipídico dos filhos, mas essa associação é mediada pelo IMC atual do adolescente. / This study assessed the effects of intrauterine growth restriction (IUGR) and prenatal variables related to fetal growth on blood lipids in adolescence. All hospital births taking place in 1982 in Pelotas were identified and this population has been followed-up since then. All male subjects were identified in 2000 when enrolling in the national army; 79% (n = 2250) were traced and 2089 blood samples were made available. 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 IUGR, maternal pre-pregnancy body mass index (BMI) and maternal smoking during pregnancy. After adjusting for confounding variables, total and LDL cholesterol levels were slightly and significantly higher among adolescents whose mothers were in the 3rd and 4th quartile of pre-pregnancy BMI. However, these
associations disappeared after adjusting for adolescent’s diet, schooling and BMI. A similar relation was observed for non-HDL cholesterol. Other associations were not significant (p>0.05). A higher maternal pre-pregnancy BMI seems to have an influence on the lipid profile of their offspring. Yet, this association is mediated by current BMI.
