    Abstract:
    OBJECTIVE: To study the relationship between the serum levels of adipocyte fatty acid-binding protein (A-FABP) level and type 2 diabetes mellitus in a community population. METHODS: A total of 255 residents (aged 45-85 years) were randomly selected from 4 communities in Guangzhou to examine the fasting plasma glucose (FPG), 2-hour postprandial blood glucose (2hPG), glycosylated hemoglobin (HbA1c), body mass index (BMI), waist circumference (WC), hip circumference (HC), waist-to-hip ratio (WHR), blood pressure (BP), triglyceride (TG), cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C). The insulin resistance index (HOMA-IR) was calculated and enzyme-linked immunosorbent assay (ELISA) was used to determine serum A-FABP and fasting insulin (FINs) levels. The cases were divided into 3 groups according to blood glucose level, namely the normal group (group A, n=90), impaired glucose tolerance group (group B, n=85), and diabetic group (group C, n=80), and the A-FABP levels were compared between them. RESULTS: Compared with group A, the subjects in groups B and C showed significantly increased FPG, 2hPGh, HbA1C, HOMA-IR, systolic blood pressure (SBP), and waist circumference (P=0.000) as well as FINs, WHR, diastolic blood pressure (DBP) , TG, and HDL-C (P=0.038, 0.047, 0.01, and 0.046, respectively). Compared with group B, group C showed significantly higher FPG, 2hPG, HbA1c, TG, and SBP (P=0.00), with also higher levels of FINs, BMI, WC, DBP, and HDL-C (P=0.012, 0.006, 0.03, 0.019, and 0.029, respectively). A-FABP increased significantly in the order of group A, B, and C (P=0.00), and this result was not affected by the differences in age between the 3 groups (P>0.05). A-FABP level was positively correlated to FPB, 2hPG, FINS, WHR, BMI, WC, SBP, and HOMA-IR, but inversely to TG and HDL-C (P=0.00). CONCLUSION: Elevated serum A-FABP is closely related to glucose metabolism disorder, and A-FABP may serve as a useful marker for the occurrence and development of type 2 diabetes in the community population.
