| 1 | Obesity is associated with the Arg389Gly ADRB1 but not with the Trp64Arg ADRB3 polymorphism in children from San Luis Potosí and León,México显示文摘This research was designed to analyze the possible associations of Arg389 Gly ADRB1 and Trp64 Arg ADRB3polymorphisms in children with obesity.A cross-sectional study included 1,046 school-age Mexican participants(6-12 years old) from the cities of San Luis Potosi and Leon.Children were classified as non-obese or obese according to their body mass index(BMI) percentile;obese children had a BMI≥95th percentile for sex and age.Biochemical data were collected.Polymorphisms were detected using TaqMan qPCR assay.A logistic regression analysis was used to calculate the risk of obesity based on genotypes.Differences were found between groups where obese children had a significant increase in systolic and diastolic blood pressure,fasting plasma glucose,insulin,HOMAIR,LDL-cholesterol,triglycerides,and lower HDL-cholesterol compared with the normal weight group(P < 0.05).The distribution of allele frequency in the population was Arg = 87.4 and Gly = 12.6(Hardy Weinberg equilibrium x^2= 3.16,P = 0.07);Trp = 81.5 and Arg= 18.5(Hardy Weinberg equilibrium x^2 = 2.2,P = 0.14) for ADRB1 and ADRB3,respectively.Even though no different frequencies of Arg389 Gly polymoiphism between groups were found(P = 0.08),children carriers of one Gly389,ADRB1 allele had a risk for obesity of OR = 1.40(95%CI,1.03-1.90,P =0.03) after adjustment for age and gender.No other association was found for Trp64 Arg ADRB3 polymorphism.Only the Arg389 Gly ADRB1 polymorphism was associated with risk for obesity in Mexican children. | Celia Aradillas-García Miguel Cruz Elva Perez-Luque Maria E.Garay-Sevilla Juan M.Malacara Aduna R Jesús Peralta Ana Burguete-García Jorge A.Alegría-Torres | 2017 | The Journal of Biomedical Research2017，31，1： | 0 |
