摘要:

目的 探讨雄激素受体基因CAG、GGN重复片段多态性与身体质量指数(BMI)、腰臀比(WHR)之间的关联性。方法 研究对象来自宁夏医科大学2011级健康学生共 654 例, 男性280例,女性374例,平均年龄(20.35±1.24)岁。用ABI 3730XL测序仪测定AR基因的(CAG)n及(GGN)n重复数目,直接测量法测得身高、体重、腰围与臀围。 结果 BMI与WHR的分布存在性别差异。较长GGN等位基因与女性BMI呈正相关(P<0.05),AR基因的(CAG)n与女性BMI无相关性(P>0.05);男性AR基因的(CAG)n及(GGN)n与BMI及WHR无相关性(P>0.05)。 结论 BMI与WHR在不同性别间的分布存在差异性;较长GGN等位基因与女性BMI存在关联性。

Abstract:

Objective Body mass index (BMI) and waisthip ratio (WHR) are sexually dimorphic. The main reason for the stability of sexual dimorphism of BMI and WHR is the sex-hormone profile of an individual. Variability in testosterone levels has been related to BMI and WHR. At the molecular level, the effect of androgens is mediated through the activation of androgen receptor (AR). The CAG/GGN repeat polymorphisms of the AR gene are associated with AR activity. Thus, we aimed to investigate the effect of CAG/GGN repeat polymorphisms in AR on BMI and WHR in Chinese. Methods BMI was calculated as weight/height squared (kg/m2). WHR was calculated as waist/hip. AR CAG/GGN repeat polymorphisms were genotyped by ABI 3730 DNA analyzer. Results BMI and WHR were different between males and females. The longer GGN allele was positively associated with BMI of females (P<0.03). There was no association between WHR and AR CAG or GGN polymorphisms (all, P>0.05).We did not find any relationship between AR CAG polymorphism and BMI(all,P>0.05). Conclusion The relationship between AR CAG/GGN repeat polymorphisms and BMI/WHR are likely to be more complex than previously appreciated.
