Obesity is a prevalent multifactorial disease whose main complication is dyslipidemia. Serum lipid levels also depend on genetic factors including the Taq1B variant of the CETP gene, which is suggested to be influenced by environmental factors and adiposity. Therefore, this study aimed to determine the effect of the Taq1B CETP variant on serum lipid levels associated with anthropometrical variables. 165 women from western Mexico were enrolled in this cross-sectional study. Weight and body fat were measured by bioimpedance and waist circumference with a measuring tape. Serum lipid levels were determined by dry chemistry. The Taq1B CETP variant was analyzed by allelic discrimination. Women with abdominal obesity and the B1B2/B2B2 genotype had significantly higher total cholesterol levels (195.17 [185.95-204.39] vs. 183 mg/dL [169.83-196.16], p = 0.007) and low density lipoprotein (118.84 [110.65-127.03] vs. 113.84 mg/dL [102.37-125.31], p = 0.037) than carriers of the B1B1 genotype. Likewise, subjects with excessive adiposity and the B1B2/B2B2 genotype showed significantly higher total cholesterol levels (195.05 [186.04-204.06] vs. 182.40 mg/dL [169.03-195.76], p = 0.003) than those with the B1B1 genotype. Women with abdominal obesity or excessive adiposity, who are also carriers of the B1B2/B2B2 genotype, have higher serum lipid levels than women with the B1B1 genotype. Show less

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.
