Abstract
Background & Objective: Today obesity and depression are two important diseases which are growing all over the world and threat the human health. That how much these two affect each other is a major health question. This study aimed to investigate the relationship between body mass index (BMI) and depression in female students of Ardabil University of Medical Sciences. Method: In a descriptive study 230 female students were selected through classified random sampling and their height and weight were measured. To measure the rate of depression a Beck test, and to analyze the data a descriptive method, and finally to indicate the relationship between BMI and depression Pearson correlation through SPSS15 software were used. Results : 40% of the students in the depression test were in the normal level, 29% had mild depression, 24% moderate depression and 7% severe depression. In addition 77% of the students, regarding body mass index were in an acceptance level, 14% were overweight and 9% were underweight. Pearson correlation method showed that there was a positive significant relationship between BMI and depression among female students (p≤ 0.01). Conclusion: The prevalence of depression in female students of university is 60% and the prevalence of obesity is 14% and there is positive significant relationship between BMI and depression.

Abstract
Background & Objectives: Food consumption for its hedonic properties can result in caloric intake exceeding requirements and is considered as a major culprit in the rapidly increasing rate of obesity. We compared the dietary patterns and the hedonic questionnaire score in obese and non-obese women. We also investigated the relation between the score of this questionnaire and variety of food items. Methods: This case-control study was conducted on 140 women aged 17-44 years that had referred to obesity club at district 4 of Tehran in 2011. Food intake and hedonic score were determined using validated semi-quantitative 168-item food frequency questionnaire and 21-item hedonic questionnaire, respectively. Logistic regression was used to determine the association between obesity and the dietary patterns identified by factor analysis and hedonic hunger score. Results: Two dietary patterns were identified as healthy and unhealthy patterns. The adjusted odds ratio of obesity didn’t show any significant trend in none of the dietary patterns. The mean hedonic questionnaire score was higher in case than control group, significantly (p<0.05). The adjusted odds ratio of obesity, for the second and the third tertiles of this questionnaire versus the first tertile of this, was 2.8 and 10.8, respectively (p<0.05). Conclusion: This study shows that there is no difference between the dietary patterns of obese and nonobese women while there is a positive association between hedonic hunger and obesity. It seems that hedonic hunger may lead the obese women to consume unhealthy food choices.

Abstract
Background: Obese patients are at high risk of numerous chronic diseases including diabetes, hypertension, heart disease, dyslipidemia and stroke. Recently researchers focused on complementary medicine along with routine treatments to reduce obesity complications. Therefore we aimed to investigate the effects of omega 3 fatty acids supplementation on serum lipid profiles, C-peptide and fasting blood glucose in obese individuals. Methods: In this randomized clinical trial 56 obese volunteers with the mean age of 33.94±8.15 years were assigned into the supplemented (n=30) and placebo (n=26) groups, given two omega 3 fatty acids soft gel (360 mg EPA and 240 DHA) or placebo respectively for 4 weeks. At the onset and the end of the intervention, blood samples were collected after overnight fasting and serum lipid profiles, C-peptide and fasting blood glucose were measured. Data were analyzed with SPSS program and p-value less than 0.05 considered as significant. Results: In comparison with placebo group, omega 3 supplementation resulted in a significant decrease in the mean triglyceride (108.37±11.22 mg/dl vs 148.84±59.40 mg/dl). After 4 weeks, the mean C-peptide concentrations increased in both groups but elevation in omega 3 group was more dramatic (p<0.01). However, we didn’t find any significant changes in the mean total cholesterol, LDL-C and HDL-C levels. Conclusion: Our finding indicated that 4 weeks Omega 3 supplementation leads to amelioration in some of serum lipid profiles indices and insulin secretion in obese individuals. Although, further studies are needed to achieve precise results.

Abstract
Background & objectives: Epidemiological and clinical studies have shown a close relationship between asthma and obesity. The present study examined the effect of obesity on the airway response to methacholine and the number of inflammatory cells in the bronchoalveolar fluid of ovalbumin-sensitized male rats.
Methods: Twenty-four male Wistar rats were divided into 4 groups: normal diet (C+ND), OVA‐sensitized with the normal diet (S+ND), high-fat diet (C+HFD) and OVA‐sensitized with high‐fat diet (S+HFD). All animals were fed for 8 weeks with standard diet or high-fat diet, and then were sensitized with ovalbumin or normal saline for another 4 weeks while receiving the designed regimens. At the end of the study, the number of inflammatory cells in bronchoalveolar fluid (BALF) and tracheal responsiveness to methacholine were examined.
Results: In diet-induced obesity groups, weight and obesity indices increased (p<0.05 to p<0.001). The results also showed that tracheal responsiveness to methacholine in S+HFD group compared to S+ND group, was significantly increased (p<0.05). In addition, the number of inflammatory cells in the BAL, in the S+HFD group was higher than other groups (p<0.001).
Conclusion: the results of this study suggest that the response of the airways to methacholine and the number of inflammatory cells are increased in obese-asthmatic male rats.

Abstract
Background & objectives: Preptin and adropine are peptide hormones that play an important role in the controlling of obesity by regulation of carbohydrate metabolism. The purpose of the present study was to investigate the effect of aerobic training on preptin, adropine and insulin resistance in men with overweight.
Methods: In this clinical trial study, 18 overweight and obese men (age 58.39±3.92, body mass index 28.75±1.23) were selected and randomly divided into two groups (control and exercise). Exercise group participated in an aerobic exercise program for eight weeks, five sessions per week (with an intensity of 65 to 85% of maximum heart rate, 40 minutes). Two days before and after the protocol, fasting blood samples were taken. Preptin and adropine were measured by ELISA. Data were tested using independent t-test and ANCOVA at a significance level of p<0.05.
Results: The level of preptin in the experimental group was significantly reduced compared to the control group (p=0.001) and the pretest (p=0.000). Also, the adropine level in the experimental group increased significantly compared to the control group (p=0.000) and the pretest (p=0.000). Also, Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) values in the exercise group compared to the control group (p=0.000) and pretest (p=0.000) showed a significant decrease.
Conclusions: Exercise improved glycemic index in obese and overweight men by improving the levels of preptin and adropine. It seems that aerobic exercise can be an effective intervention method to control and prevent the occurrence of metabolic diseases in these people.

Abstract
Background & objectives: Obesity and a high-fat diet (HFD) lead to metabolic disorders in the liver by affecting the signaling pathways of fat and glucose metabolism. Exercise and dietary habits are of special interest to prevent and counteract obesity and its associated metabolic disorders. Also, Capsaicin ameliorates diet-induced obesity in rodents and humans. The aim of the present study was to examine the effect of aerobic exercise and capsaicin on the gene expression level of AMP-activated protein kinase (AMPK) and protein kinase B (Akt) in the liver of HFD rats.
Methods: in this experimental study, 40 male Wistar rats were fed a normal diet (ND, n=8) or high-fat diet (HFD) (n=32) for 8 weeks. After 8 weeks, all rats were divided into 5 groups: normal diet (ND), high-fat diet (HFD), high-fat diet-training (HFDT), high-fat diet-capsaicin (HFDCap), high-fat diet-training-capsaicin (HFDTCap). Training groups have performed a moderate- intensity aerobic running program (60-50% VO2max, at 15-25 m/min, 30-60 min/day, and 5 days/week) on a motor-driven treadmill for eight weeks. Capsaicin (4 mg/kg/day) was administered orally, by gavage, once a day.
Results: Induction of diabetes was associated with decreased AMPK expression (p=0.0001) and increased Akt (p=0.0001). The results showed that training and capsaicin significantly increased AMPK expression (p=0.032 and p=0.045, respectively) and decreased Akt expression (p=0.045 and p=0.049, respectively) in HFD rat hepatocytes. Also, the interaction of training and capsaicin had a significant effect on the expression of AMPK (p=0.017) and Akt (p=0.0001).
Conclusion: The results showed that HFD impaired hepatocyte function and that aerobic exercise and capsaicin increased lipogenesis with increasing AMPK and decreasing Akt expression. However, the interaction effect of training with capsaicin was greater.

Abstract
Background: Given the high prevalence of obesity and overweight and the detrimental impact on the mental health of affected people, the objective of this study is to examine the effectiveness of narrative therapy on social physique anxiety in obese and overweight women.
Methods: The current research was a semi-experimental type, with a pre-test, post-test design with a control group. The study population for this research consisted of all obese and overweight women in Tabriz city in 2023. 30 women were selected by the available sampling method and were randomly divided into two groups: the experimental group and the control group. The experimental group received narrative treatment in 8 sessions of 90 minutes, while the control group did not receive any treatment and was placed on the waiting list. At the end of the treatment period, a post-test was performed in both groups. The Social Physique Anxiety Scale by Hart et al. (1989) was used as the measurement tool. The collected data were analyzed using descriptive statistics (mean and standard deviation) and inferential statistics (covariance test with repeated measures) by SPSS-24 software.
Results: In the pre-test, the mean and standard deviation of social physique anxiety in the experimental group were 44.33±2.289, while in the control group, it was 43.67±3.063. In the post-test stage, the values for social physique anxiety in the experimental group were 36.33±3.117, while in the control group, it was 43.80±3.385. The results indicated the effectiveness of narrative therapy (p<0.001). In the follow-up stages, it was found that the effects of narrative therapy are lasting (p<0.001).
Conclusion: According to the results, it can be concluded that narrative can be an effective method for reducing social physique anxiety in obese and overweight women.

Abstract
Background: Obesity is a major health problem worldwide. Therefore, the purpose of this study was to determine the effects of l-carnitine supplementation on physical factors related to health and lipid profiles in obese female children with basic gymnastics exercises.
Methods: In this quasi-experimental study, with a pre-test-post-test design and a placebo group, 60 obese children among the girl students of Isfahan with BMI=30.28 kg/m2 were selected purposefully and were divided into 4 groups (Basic gymnastics training, L-carnitine consumption, Combined, and Placebo). The training protocol was implemented for 12 weeks, three times a week, and 45 minutes for each session. Furthermore, the groups of L-carnitine consumption and combined used L-carnitine tablets with a dose of 2 g per day for 12 weeks. To analyze the data, multivariate covariance, and post hoc Tukey tests were used.
Results: A significant increase in Cardio-respiratory endurance, muscular endurance, muscular strength and flexibility was observed in both basic gymnastics training and combined groups (p≤0.001). In addition, a significant decrease in total cholesterol, triglyceride, and LDL and a significant increase in HDL were observed in the basic gymnastics training, and combined groups (p≤0.002). Also, the changes caused by the combined group on all variables were significantly better than other groups.
Conclusions: These findings indicate the beneficial effects of basic gymnastics training along with L-carnitine supplementation on physical factors related to health and lipid profile in obese children. Therefore, the combined use of basic gymnastic exercises and L-carnitine supplementation can be useful to improve these variables.
