Background and aim: Adiponectin, is an adipose tissue-specific adipokine, that circulates in human plasma at high levels, although lower levels are noted with insulin resistance and atherosclerosis. We investigated the relationship of adiponectin concentrations with dietary factors and some of the cardiovascular risk factors in patients with T2DM.
Methods and results: Totally 107 patients with T2DM were recruited from the out patients clinic of Shariati Hospital, Tehran, Iran. Patients were evaluated for laboratory and anthropometric measurements including serum adiponectin, fasting insulin, FPG, OGTT, HbA1c, HOMA-IR, hsCRP, weight, height, BMI and WHR. Nutrients intakes were obtained via 24-h recall from each patient in three successive days. Nutrients and data analysis were done using FPII and SPSS version 13 softwares. The mean of log10-transformed serum adiponectin concentration was 0.79±0.27μg/ml. The univariate linear regression analysis could not show any significant relation between the log of serum adiponectin and dietary factors. In multivariate linear regression after multiple adjustment, the log of serum adiponectin was independently associated with WHR (P=0.02, t=-2.33), HDL-C (P=0.050, t=2.03) and markedly but not significantly with age of patients (P=0.058, t=1.92).
Conclusions: Our findings showed that WHR, one of the important cardiovascular risk factors, can modulate independently adiponectin levels of T2DM patients in inverse manner. Also, the age of patients and HDL-C levels have marked positive effect on circulating levels of this adipocytokine. Thus, adiponectin might be a useful biomarker to prevent developing CVD in type 2 diabetes.
