RESUMO

<p><b>OBJECTIVE</b>To study the relationship between the inheritable factor and environmental factors of type 2 diabetes mellitus in humans.</p><p><b>METHODS</b>A case-control study based on 154 type 2 diabetes mellitus and 130 healthy controls was carried out in Jiangsu Province in 1997.</p><p><b>RESULTS</b>The age, family history of diabetes mellitus, hypertension history, high waist/hip ratio (WHR), high systolic blood pressure, huge fetus history, and the genotype of beta(3)-adrenergic receptor (beta(3)-AR) were the risk factors of type 2 diabetes mellitus; while occupational physical activity was protective factor of type 2 diabetes mellitus. The risk for diabetes mellitus distinctly increased while genetic factor and obesity, beta(3)-AR mutation were coexisting.</p><p><b>CONCLUSION</b>Type 2 diabetes mellitus is caused by the effect of both genetic and environmental factors.</p>

RESUMO

Objective To investigate the association betwee n the β3-adrenergic receptor gene (β3-AR) and obesity. Methods 147 patients with obesity and 106 controls were selected. Genotype of the β 3-AR was determined by polymerase chain reaction (PCR) and restriction fragme nt length polymorphism methods (RFLP). Body mass index (BMI) was detected. Results The frequency of Arg64 allele of β3-AR gene in the obesit y g roup (20.3%) was significantly higher than those in the control group (10.2%) ( P=0.001) . The distribution of Trp64Arg and Arg64Arg genotype in the patient group (38.7% and 0.9%) were both higher than that in the control group (19.0% and 0.7%). In the female subj ects, the Trp64Arg mutation and frequency of Arg64 allele of the β3-AR gene in the obesity group(40.6% and 20.3%) were also higher than those in control (16 . 7% and 9.5%)(P<0.01). Conclusions These results suggest th at the Trp64Arg mutation of the β3-adrenergic-receptor gene may be associat ed with increased body fat.
