Resumo (PT): Objective To evaluate how the lipid profile associates with apolipoprotein (apo) E gene polymorphism, plasma adiponectin level, and body mass index (BMI) z score in Portuguese youth. Design Transversal cohort study. Setting Hospital de São João and Hospital de Crianças Maria Pia, Porto, Portugal, between May 2006 and March 2007. Participants One hundred thirty-eight obese children and adolescents (62 boys; mean age, 10.8 years [range, 4-16 years]). Participants were grouped according to (1) apo E polymorphism: presence of the apo E alleles 2 or 4 in E2 (n = 11) and E4 (n = 31) carriers, respectively, or as E3/E3 (n = 94) (carriers of E2/E4 [n = 2] were excluded from apo E analysis because they carry both alleles) and (2) BMI z score: group 1, BMI z score less than 2 (n = 31); group 2, BMI z score of 2 or more and less than 2.5 (n = 65); and group 3, BMI z score of 2.5 or more (n = 42). Main Outcome Measures Lipid variable comparisons between apo E polymorphism and BMI z score groups and influence of BMI z score and adiponectin level, adjusted for apo E polymorphism, on total cholesterol to high-density lipoprotein cholesterol and apo A-I to apo B ratios. Results E4 carriers presented with a worse lipid profile when compared with E2 and E3/E3 carriers. There was also a clear risk of worsening for the group with the highest BMI z score. Apolipoprotein E polymorphism, BMI z score, and adiponectin level were significantly associated with total cholesterol to high-density lipoprotein cholesterol (standardized β coefficient = 0.283, 0.354, and –0.292, respectively; P < .001 for all) and apo A-I to apo B (standardized β coefficient = –0.372, –0.284, and 0.327, respectively; P < .001 for all) ratios. Conclusion Our data suggest a more atherogenic lipid profile for some apo E genotypes and for increasing BMI z score, whereas adiponectin level seems to play a protective role. <br> <br>
