Abstract
Background:Obesity is a serious public health problem in developing countries due to its association with the cardiovascular risk factors. Childhood obesity is responsible for a number of different complications both during childhood and adulthood. The aim of the present study was to determine the cardiovascular risk factors in overweight and obese Iranian children.
Methods: We screened 13086 children aged 7-12 years by measuring waist circumference. Those with a waist circumference ≥61 cm were selected for further evaluation. Anthropometric measurements were done and blood samples were taken from 563 enrolled overweight/obese children (284 boys and 279 girls). We determined cardiovascular risk factors (including fasting total cholesterol, LDL-C, HDL-C, triglycerides, blood pressure). In addition we measured the fasting blood sugar, insulin, apo-A , apo-B and leptin levels.
Results: Only 2.7% of overweight or obese children had no risk factors. While, 20.6% had one and 70.85% had two or more risk factors. The prevalence of high total Cholestrol levels was 42.6%. HDL-C showed an acceptable level in 92.4%of children .There were strong correlations between BMI and serum apoB and leptin levels (p<0.005).
Conclusion: The high prevalence of cardiovascular risk factors in overweight and obese Iranian children emphasizes the need for prevention and control of childhood obesity from early childhood in our country.

Abstract
Background: Medical-nutritional interventions, can reduce the risk of complicationsin T1DM. There has been some conflicting data on the issue of the association between diabetes knowledge and metabolic improvement of T1DM patients. Therefore the aim of this study was to evaluate the effect of nutrition education on biochemical changes, nutritional status, knowledge, attitude and practice of patients withT1DM in Aligoodarz.
Methods: This study was a self – control quasi survey. Census sampling was used for subject selection. ِِData was collected by observation and interview techniques. Biochemical indices were measured on blood samples by standard methods and anthropometric measurements, diet survey and KAP study were carried out on 30 patients with T1DM by a nutritionist at the first and 3 months after training. All cases participated in educating programs for 12 hours. The results were analyzed by SPSS and Food processor softwares and results compared with paired t-test and McNemar test. P-values less than 0.05 were considered as significant.
Results: 30 patients with 15 – 45 years old ( Mean ± SD = 30.8 ± 11.3 ) participated in study all participants were educated. Mean duration of diabetes was 10.9±6.44 years. FBS, HbA1c, total cholesterol and LDL-C levels decreased significantly. After educating interventions also hypoglycemic attacks reduced. Macronutrients intake were in recommended ranges for diabetic patients. Simple carbohydrates and cholesterol intakes decreased and dietary Folate, Vit c and fiber increased. Calcium intake was less than RDA. Both knowledge and practice scores increased significantly (P<0.001). Attitude was changed for some items significantly.
Conclusion: Findings of this project emphasyzed on the importance of nutrition education to patients with T1DM. It may significantly changes biochemical indices, dietary fiber and simple carbohydrate and improves metabolic control in T1DM. And the patients KAP scores increased. Thus appropriate nutrition education as well as insulin therapy are the main factors in metabolic control of T1DM.

Abstract
Background: Chronic diabetes is substantially associated with circulatory disorders in lower limbs. Vacuum-Compression Therapy (VCT) has been commonly used in treatment of peripheral circulatory disorders. VCT is based on intermittent alteration of Positive- Negative pressure phases. The purpose of this study was to determine effects of VCT on diabetic subjects' peripheral blood flow.
Methods: In this Before-After and case-series study, 18 type 2 diabetic subjects with diabetic neuropathy and/or peripheral vascular disease (PVD) completed the study. Subjects received 45 min of VCT for 10 sessions three times weekly. Blood flow (calf+foot) was measured via venous occlusion plethysmography.
Results: Among Variables of "Arterial Inflow", "Venous Outflow", "Venous Capacity", "Post-ischemic Reactive Hyperemia" and "Peak Flow of Reactive Hyperemia", only "Venous Outflow" significantly improved after 10 sessions treatment via VCT (P<0.05).
Conclusions: Arterial blood inflow, which was the most important determinant evaluated in this study, was not increased via VCT. Additional studies are required to investigate the effective VCT parameters and duration of each session and number of sessions, considering progressive and deteriorative natural history of diabetes.

Abstract
Objective: Health of old people is one of the critical issues in many societies that needs to accurate
health policy making and adjust planning in health issues of elderly. The present study designed to
compare the efficacy of the two traditional and electronic training methods in nutritional issues in order
to life style modification in old people to develop of healthy elderly.
Methods: This survey was a quasi-experimental method via applying the Pre-test and Post-test among
65+ years old people in a retirement association of Sari province, Mazandaran state. By simple random
sampling method, 60 old people were selected, and then trained in two separated classes to 15 persons as
women and men (30 persons) via film technique. The other method was a traditional which applied in the
two separated classes of 15 persons as women and men (30 persons) by book technique. The
questionnaire applied to measure of nutritional knowledge made up by the health center. Data were
described by using SPSS software in accordance to descriptive statistics indexes (mean and standard
deviation), and inferential statistics indexes (independent T and dependent T) were used in order to
generalize results.
Findings: The mean score of increasing knowledge in training group by film was 18/57 and the mean
score in training group by book was 16/90 (T =5/299, df= 58). To satisfaction evaluating, the mean score
in training group by film was 59 and the mean score in training group by book was 35/73 (T =1/96,
df=58).
Conclusion: Based on results training of old people by electronic method as a film is more effective than
traditional method to increasing of nutritional knowledge in elderly. On the other hand, they had more
satisfaction to life style modification by using film method in comparison with traditional method as
book reading technique. Also, the training cost of the elderly via educational film is lower than training
by book. So, should be suggested to consider in training by film rather than book as an efficient and
effective method to improve of elderly health.

Abstract
Background: The purpose of this study was to compare three intensities of acute aerobic exercise on plasma visfatin concentration in type 2 diabetic males. Methods: Ten men with type 2 diabetes (mean ± SD age 52.6 ± 3.6 years, height 171.3 ± 6.7 cm, Weight 87.58 ± 4.7 kg) participated in the study. In the first session, anthropometric measurements, body composition, and peak oxygen uptake (VO2peak) was measured in all subjects. In the next sessions, subjects completed three acute aerobic exercises on separate days in a crossover design. The three exercise trials performed at intensity of 40%, 60%, and 80% VO2peak after fasting for at least 10 hours. Energy expenditure was 300 kcal for each exercise trial. Blood samples before exercise, immediately after and 24 hours after exercise were collected for measuring visfatin, glucose and insulin. Results: The results showed no significance interaction (p>0.05) between exercise and sampling time. This analysis also revealed significance in the main effects (p>0.05) of the two factors (exercise and sampling time). Pearson correlation showed that there was significant relationship between visfatin and insulin (p<0.05). Conclusion: According to the present results, we can conclude that acute aerobic exercise at different intensities with 300 kcal energy expenditure will not change visfatin levels in type 2 diabetes.

Abstract
Background: Thyroid cancer is the most common form of endocrine cancer. The age and gender-adjusted incidence of thyroid cancer has increased faster than that of any other malignancy in recent years, with the increased incidence seen in both genders, all ethnic backgrounds and all sizes of thyroid cancer. It appears that the rise in thyroid cancer incidence is not only due to medical surveillance and improved disease detection. In Iran, also scattered studies had been accomplished in different provinces and requirement to more attention and planning for thyroid cancer. Thyroid cancer’s control and prevention requires to the evidence–based strategies in different population groups based on national and provincial comprehensive studies on the prevalence and incidence. Thus we aimed to provide the comprehensive information about thyroid cancer prevalence and trend in national, provincial levels among Iranian population.
Methods: In this study we used some steps respectively to show how thyroid cancer prevalence changes in 1990 to 2010 between different provinces. We aggregate cancer registry data set by province, age categorized, gender and merge with other national covariates that were gathered in Iran. Then, linear regression model and logistic regression model were used to modeling and predicting for other provinces and years.
Results: Mean of thyroid cancer prevalence displayed that prevalence increased with increase in years especially more rapidly from 2002-2010 the prevalence rates were estimated to be (0.0-0.25) and (4.2-13.7) per 100000 in 1990 and 2010 respectively and increased in both females and males. Female to male ratio was 2.5. Highest prevalence thyroid cancer were in four provinces of Iran, Isfahan (mean rate 4.3 per 100000), Yazd (mean rate 4.1 per 100000), Tehran (mean rate 4 per 100000) and Qazvin (mean rate 3.1 per 100000) respectively.
Conclusion: Iran map displayed with increase in years, thyroid cancer prevalence become larger. Additional research on the risk factors for thyroid cancer is needed to explain the difference of thyroid cancer prevalence between provinces.

Abstract
visfatin secreted by various factors, including cytokines such as TNF-α and IL-6 is affected. The purpose of this study was to evaluate the effect of eight weeks of combined training (resistance circular - aerobic) visfatin concentration, IL-6 and TNF-α in obese men with type II diabetes.
Methods: The population of the research was all men with diabetes type II in District 2 of Ahwaz. Twenty four patients with diabetes type II, aged 40-55 years and fasting blood glucose lower than 200 mg /dl were selected by purposive sampling. First, the anthropometric variables and body composition were measured, then subjects were randomly divided into two groups (experimental, n=12 and control, n=12). Combined exercise training was done for 8 weeks (5 days/week, 30 to 50 minutes) for experimental group. To analyze the changes in the covariance analysis and dependent t test measured variables at a significance level of p≤05.
Result: After eight-week combined exercise training, fasting blood glucose and plasma visfatin significantly decreased p≤05. But no significant changes were observed in the levels of IL-6 and TNF-α p≥05. Also, the inverse relationship between plasma visfatin with IL-6 and TNF-α was observed (P≤ 0.05).
Conclusion: Eight weeks of combined training despite a positive effect on plasma visfatin, due to no significant changes in plasma IL-6 and TNF-α in patients with type 2 diabetes, it seems this type of exercise in reducing obesity and visceral fat and thereby reducing plasma visfatin is appropriate, but the potential change in IL-6 and TNF-α does.

Abstract
Non-Communicable Diseases (NCDs) are the major cause of premature death and disability due to diseased globally, imposing a heavy burden on the health systems. Four main categories of NCDs are cardiovascular diseases, neoplasms, diabetes, and chronic respiratory diseases. Iran, the second greatest country in the Middle East Region, has been through an important transition period of communicable diseases toward NCDs in the last decades. One of the effective approaches to control NCDs is implementation of population-based studies and interventions, trying to reduce risk factors and incidence of NCDs through investigations in the populations. Endocrinology and Metabolism Research Institute (EMRI) and Non-Communicable Diseases Research Center (NCDRC) are the pioneers trying to study and control various NCDs during the last decades in Iran. In this review, we are going to inspect some of the major completed and ongoing projects of this research institute to highlight valuable efforts to reduce burden of NCDs in Iran, and make a successful example for national and regional public health policy makers and authorities.

Abstract
Background: BDNF protein is the important neurotrophin that is involved in cognitive function. Diabetes can lead to impaired function and is a neurocognitive disorder's factor in hippocampus. Therefore, the purpose of this study was to evaluate the effect of 8 weeks of concurrent training on BDNF levels in the brain hippocampus and cognitive function of streptozotocin-induced diabetic rats.
Methods: 40 of Sprague-Dawn rats were randomly divided into four groups: healthy inactive, non-healthy concurrent exercise, diabetic group without exercise, and diabetic concurrent exercise. Rats in the training groups performed concurrent training for 8 weeks. After 8 weeks, subjects' memory was assessed using a cognitive function test in a water maze. BDNF levels in the hippocampus were measured by Western blotting. One-way analysis of variance and LSD post hoc test were used to analyze the data.
Findings: The present study showed that eight weeks of concurrent exercise resulted in a significant reduction in fasting blood sugar in the healthy exercise group compared to the diabetic group. A significant decrease in BDNF levels of the cerebral hippocampus was also observed in the diabetic exercise group compared to the diabetic group. In addition, the level of memory function in healthy exercise and diabetic exercise groups was significantly higher than healthy control and patient control.
Conclusion: Concurrent exercise reduces BDNF hippocampus and increased cognitive function in the exercise group compared to the control group. As a result, it can be said that this type of exercise is very effective in improving the complications of type 2 diabetes.

Abstract
Background: Aging and consuming a high-fat diet lead to increased oxidative damage to various tissues, oxidative stress is a critical factor in the aging process that can cause direct damage to cellular structure. This study aimed to investigate the Effects of 8 Weeks of HIIT Training on the Nrf2 Gene Expression, lipid peroxidation and Insulin resistance in the pancreas tissue of Aged rats fed a high-fat diet.
Methods: In this experimental study, 20 aged male Wistar rats (age: 18 months and mean weight: 500±100 gr) were randomly divided into four groups including normal food control G1 (n=5), normal food + training G2 (n=5), high-fat food G3 (n=5) and high-fat food +training G4 (n=5). The high intensity interval training program was performed on a treadmill, three days a week for eight weeks. Nrf2 gene expression was performed using real-time PCR and malondialdehyde levels, glucose and insulin were measured using a kit and ELISA method. Data were analyzed by MANOVA test at the P<0.05.
Results: The results of the MANOVA statistical test on the interactive effect of training and diet indicated a significant difference in the insulin resistance index (P = 0.017 and F = 7.17). However, no significant effect was observed for the insulin factor (P = 0.30 and F = 1.13), glucose (P = 0.116 and F = 2.75), MDA (P = 0.87 and F = 0.028), and Nrf2 (P = 0.816 and F = 0.056).
Conclusion: In general, it can be stated that HIIT training in this research can improve insulin resistance by affecting the expression of the Nrf2 transcription factor gene by reducing the oxidant activity in aged rats.
