摘要
Objective To identify the association between PLIN 1237 polymorphism and obesity in Chinese Han adults. Methods A total of 994 adults （157 obese subjects, 322 overweight subjects, and 515 normal controls） were recruited from two rural communities. PLIN 1237 polymorphism was genotyped by polymerase chain reaction-restriction-fragment-length-polymorphism （PCR-RFLP）. Association between PLIN polymorphisms and obesity status was estimated by ordinal logistic regression. Results The three genotypes of,PLIN 1237 were detected with a percentage of 54.3%, 37.1%, and 8.6% in TT, TC, and CC genotypes, respectively. For the PLIN 1237 polymorphism locus, the frequency of alleles T and C was 0.73 and 0.27, respectively. The PLIN 1237 polymorphisms were in Hardy-Weinberg equilibrium. PLIN 1237 polymorphism was not associated with obesity. The odds ratio for overweight or obesity for the CC＋TC genotype was 0.8（0.4, 1.4） in women （P=-0.4） and 0.6 （0.3, 1.3） in men （P=-0.2） after adjustment for age, education, household income and alcohol consumption, smoking, and physicalactivity. Conclusion Chinese Han adults have a lower frequency of variant-allele C in PLIN1237. PLIN1237 T〉C polymorphism is not significantly associated with obesity in northern Chinese adults.
