Asociación entre polimorfismos del gen de adiponectina y estado nutricional en escolares de la comuna de Hualpén / Association between adiponectin gene polymorphisms and obesity in school age children from Hualpén, Chile
A case-control study was performed in 241 obese and 126 normal weight children (7-11 years old) from the urban community of Hualpén, Biobío region. Children were classified as normal or obese, according to age and gender-specificpercentiles defined by Centerfor Disease Control and Prevention (CDC). The analysis of serum markers was carried out using commercial kits. Adiponectin polymorphisms were determined through a High Resolution Melting (HRM)-enabled real time PCR and by DNA fragment sequencing.
Results:
The observed allelic frequencies of the studied SNPs were over 11%. The 11,377CG polymorphism was associated with a high risk of obesity, calculated by the additive inheritance model (odds ratio = 1.389, 95% confidence interval 1.001-1.929,p = 0.049).
