Dyslipidaemias result from the interaction between genetic and environmental factors, including diet disequilibrium and physical inactivity. Among the genetic factors associated with serum lipids, the Taq1B CETP polymorphism has been investigated. The B1 allele has been considered as a risk factor for dyslipidaemia because of its association with greater CETP levels and higher serum triglycerides. The present study aimed to determine the role of the Taq1B polymorphism with lipid and anthropometric variables and its interaction with diet and physical activity. In total, 215 subjects were enrolled in this cross-sectional study. Diet intake was evaluated using a 3-day food consumption record and physical activity was determined in accordance with World Health Organization recommendations. The Taq1B CETP polymorphism was determined by allelic discrimination. Subjects with the B1B2/B2B2 genotype, who had a sucrose consumption ≥5% of the total kcal day We provide evidence that subjects with inadequate environmental factors carriers of the polymorphic genotype had higher serum lipid levels than subjects with the B1B1 genotype.

Genetic variants associated with dietary intake may be important as factors underlying the development of obesity. We investigated the associations between the obesity candidate genes (fat mass and obesity-associated (FTO), melanocortin-4 receptor (MC4R), leptin (LEP) and leptin receptor) and total energy intake and percentage of energy from macronutrients and ultra-processed foods before and during pregnancy. A sample of 149 pregnant women was followed up in a prospective cohort in Rio de Janeiro, Brazil. A FFQ was administered at 5-13 and 30-36 weeks of gestation. Genotyping was performed using real-time PCR. Associations between polymorphisms and the outcomes were investigated through multiple linear regression and ANCOVA having pre-pregnancy dietary intake as a covariate. The A-allele of FTO-rs9939609 was associated with a -6·5 % (95 % CI -12·3, -0·4) decrease in the percentage of energy from protein and positively associated with the percentage of energy from carbohydrates before pregnancy (β=2·6; 95 % CI 0·5, 4·8) and with a 13·3 % (95 % CI 0·7, 27·5) increase in the total energy intake during pregnancy. The C-allele of MC4R-rs17782313 was associated with a -7·6 % (95 % CI -13·8, -1·0) decrease in the percentage of energy from protein, and positively associated with the percentage of energy from ultra-processed foods (β=5·4; 95 % CI 1·1, 9·8) during pregnancy. ANCOVA results revealed changes in dietary intake from pre-pregnancy to pregnancy for FTO-rs9939609 (percentage of energy from ultra-processed foods, P=0·03), MC4R-rs17782313 (total energy intake, P=0·02) and LEP-rs7799039 (total energy intake, P=0·04; percentage of energy from protein, P=0·04). These findings suggest significant associations between FTO-rs9939609, MC4R-rs17782313 and LEP-rs7799039 genes and the components of dietary intake in pregnant women. Show less
