摘要:
目的 研究SDCCAG8基因rs12145833多态性在儿童肥胖干预中的作用,为基于遗传背景制定儿童肥胖个性化干预措施提供科学依据。 方法 于2018年9月—2019年6月,在一项整群随机对照试验中,选取393名北京地区8~10岁儿童作为研究对象,将8所学校以1∶1比例随机分为干预组与对照组,采集唾液DNA样本,检测SDCCAG8基因rs12145833多样性。对干预组进行综合干预,对照组不采取干预,干预措施包括饮食改善、体育运动、学校与家庭支持等;基线调查及干预1学年结束时测量肥胖相关指标。采用多元线性回归与Logistic回归分析基因与干预对肥胖指标的交互作用。 结果 干预组中,TT基因型儿童相较于GT和GG基因型儿童在干预后的收缩压(β=4.56,95%CI=1.84~7.28,P < 0.01)与舒张压(β=2.59,95%CI=0.45~4.73,P < 0.05)升高得更少;对照组中,TT基因型儿童相较于GT和GG基因型儿童的收缩压升高得更多(β=-2.86,95%CI=-5.63~-0.83,P < 0.05);SDCCAG8基因rs12145833多态性与干预对儿童收缩压、舒张压、体脂率存在交互作用(P值均 < 0.05)。 结论 SDCCAG8基因rs12145833位点TT基因型儿童相比于GG和GT基因型儿童对肥胖干预更敏感,尤其在收缩压、舒张压和体脂率改善上效果较好,仍需在不同种族人群中研究SDCCAG8基因rs12145833多态性在儿童肥胖干预中的作用。 Abstract:Objective To study the role of rs12145833 polymorphism of SDCCAG8 gene in the intervention of childhood obesity, so as to provide scientific basis for formulating personalized intervention measures based on genetic background in children with obesity. Methods From September 2018 to June 2019, a total of 393 children aged 8-10 years in Beijing were enrolled in a cluster randomized controlled trial. Eight schools were randomly allocated into intervention group and control group at a ratio of 1∶1. Saliva DNA samples were collected to detect rs12145833 polymorphism of SDCCAG8 gene. The intervention group received a comprehensive intervention, while the control group received usual practice. Intervention measures included diet improvement, sports, school amd family sport. The obesity related indicators were measured at baseline and after the end of intervention 1 academic year. Multiple linear regression and Logistic regression were used to analyze the interaction between genes and intervention on obesity indicators. Results In the intervention group, children with TT genotype of rs12145833 of the SDCCAG8 gene had less increase in systolic(β=4.56, 95%CI=1.84-7.28, P < 0.01) and diastolic blood pressure(β=2.59, 95%CI=0.45-4.73, P < 0.05) than those with GT and GG genotypes. In the control group, the systolic blood pressure of children with TT genotype increased more than those with GT and GG genotype(β=-2.86, 95%CI=-5.63--0.83, P < 0.05). There was an interaction between rs12145833 polymorphism of SDCCAG8 gene and intervention on systolic blood pressure, diastolic blood pressure and body fat percentage in children(P < 0.05). Conclusion Children with TT genotype of rs12145833 in the SDCCAG8 gene are more sensitive to obesity intervention than those with GG and GT genotypes, especially in the improvement of systolic blood pressure, diastolic blood pressure and body fat percentage. Further trials to study the role of rs12145833 polymorphism of SDCCAG8 gene in the intervention of childhood obesity among different ethnic populations are needed. -
