Background & Objective: Diabetes is one of diseases in which the main part of treatment depends on the patient's responsibility. Therefore their knowledge of the various aspects of nutrition has great importance. The aim of this study was to evaluate the effect of diabetic diet education on nutritional behaviors. FBS and BMI of patients with type II Diabetes mellitus in Iranian Diabetic Association.

  Methods: 88 type II diabetic patients from Iranian Diabets Association (Karaj Branch) participated in this study. The Patients were randomly divided into two groups as experimental (44) and control group (44). Data were collected with a valid and reliable questionnaire (58questions) and checklist in two stage of before and one month after intervention.

  Results: After the intervention in the experimental group regarding diabetes and nutritional behaviors, there was a significant increase in mean score of knowledge (from 57.50 to 80.18) and a significant decrease in the mean of BMI (from 28.3 to 27.9) and in the mean of fasting blood sugar (from 167.9 to 134.5) (p<0.001). However, there was no significant change in the control group.

  Conclusion: The finding of this study indicated the efficacy of education on FBS and BMI in patients with type II diabetes.

  Background & Objectives: Obesity is an important risk factor for many diseases and hormonal and metabolic factors have a great impact on its development. The aim of this study was to investigate the relationship between leptin and growth hormones with anthropometric indices and blood glucose in healthy men.

  Methods: This study is a cross-sectional study on 30 healthy adult men aged 18-49 years in Tonekabone city during 2011-2012. Samples were randomly selected and information on anthropometric parameters (waist circumference, body mass index and waist/hip ratio), fasting blood sugar, serum levels of leptin and growth hormones were recorded and blood sampling was performed After 12 hours of fasting (at 8 am). Data were analyzed using software SPSS 15 by non- parametric Mann – Whitney and Spearman test s and multiple regression analysis.

  Results: Serum leptin levels were negatively correlated with serum level of growth hormone ( P<0.05) and positively related to body mass index ( P<0.01) , waist circumference ( P<0.01) and the body weight ( P<0.05). Inverse relationship between serum growth hormone levels with age and fasting blood glucose were observed (P<0.05). Serum levels of leptin were significantly higher in overweight and obese than normal weight subjects (P<0.01) and mean leptin levels in subjects with central obesity ( waist circumference≥94cm) were significantly higher than men without central obesity (waist circumference<94cm) (P<0.01).

  Conclusion: This study showed that growth hormone level was negatively correlated with serum level of leptin. Low serum growth hormone and high serum leptin levels were associated with obesity and upper body fat distribution. Obesity and abdominal obesity are also associated with increased risk of metabolic syndrome
