Objective To research the prevalence and epidemiological characteristics of overweight and obesity in Han population receiving physical examination in northern Guangxi,and investigate the relationship between single nucleotide polymorphisms( SNPs) of the adiponectin gene-11377 and MS. Methods 5 318 adults in Han popula-tion were selected from June 2012 to December 2012 with physical examination,biochemical inspection and ultra-sonic examination. A total of 80 overweight and obesity subjects were selected as study group. And 80 normal adults were selected as control group. Detection of two groups of adiponectin gene-11377C/G single nucleotide polymor-phisms,and carries on the analysis. Results ① The prevalence of overweight and obesity in this sample was 36. 9%. Compared to female population,male participants showed a much higher prevalence(46. 4% vs 26. 0%,P0. 05 ) . Clinical variables were no significant difference among different genotypes in overweight and obesity and control groups ( P >0 . 0 5 ) . Conclusion ① It has higher prevalence of obesity and overweight in Han population receiving physical examination in northern Guangxi. ②The adiponectin gene SNP-11377C/G may be not associat-ed with overweight and obesity in Han population receiving physical examination in northern Guangxi.%目的：对桂北地区汉族体检人群肥胖及超重进行流行病学调查,并探讨脂联素( APN)基因-11377位点单核苷酸多态性( SNPs)与肥胖及超重的相关性。方法抽取参加健康体检的汉族成人5318例进行体格检查、生化指标检测和肝脏B超检查。同时选择肥胖及超重患者(肥胖及超重组)和健康者(对照组)各80例,检测两组人群SNP-11377C/G,并进行分析。结果①肥胖及超重患病率为36.9%,男性肥胖及超重患病率明显高于女性(男46．4% vs 女26．0%,P0．05),两组APN基因-11377C/G不同基因型与临床变量比较,差异均无统计学意义(P >0．05)。结论①桂北地区汉族体检人群中存在较高的肥胖及超重患病率。② APN基因SNP-11377C/G与桂北地区汉族体检人群肥胖及超重发病可能无明显相关性。
