Abstract
Background: Obesity and overweight, as the most common metabolic disorders, are great health problem during recent decades. Obesity takes a role as independent or concordant risk factor for many diseases. So, it has a considerable share in burden of morbidities and mortalities. Urbanization and its consequences in increasing of incomes and per capita energy uptake, besides the notable reduction in physical activities are the main causes of increased rates of obesity in developing countries. This survey has been conducted to evaluate the obesity and overweight status and their pattern among the inhabitants of 25-64 aged in 17th zone of Tehran, selected as Population Lab region.
Methods: This study is a part of the Cardiovascular Risk Factors Survey in the Population Lab region. This survey has been designed and conducted based on MONICA/WHO project. A total of 1573 people have been recruited and assessed on age, weight, height, waist and hip circumferences. Body mass index (BMI), waist circumference (WC) and waist-to-hip ratio (WHR) were determined for comparing between groups.
Results: There was a significant difference in mean BMI between two sexes (26.13 kg/m2 in men vs. 28.86 kg/m2 in women). As well, WC and WHR were diverse between men and women (WC: 91.70 cm vs. 89.15 cm WHR: 0.91 vs. 0.85, respectively). Obesity prevalence was 18.6% among men and 38.3% among women. Prevalence of high WC and abnormal WHR were higher among women than men.
Conclusion: These results revealed that prevalence of obesity among adults was very high. The prevalence in women was more than two times than in men. This finding may be in part because of little physical activity and high proportions of carbohydrates intake instead of protein in daily energy uptake and also because of physiological differences among women. Proper and effective planning to achieve applied strategies for improving the social knowledge and awareness and also improving the life style and nutrition status of the people is highly necessiated.

Abstract
Background: Plasma concentration of adiponectin was found to play an important role in regulation of glucose metabolism, insulin resistance and conditions commonly associated with obesity. The aim of this study was to assess adiponectin level and its relation with percent of body fat mass and insulin sensitivity in over-weight men.
Method: This study was conducted on two groups of type 2 diabetic (n=20) and non-diabetic (n=20) overweight adult men. Serum level of adiponectin (ELIZA), FBS (GOD-PAP), fasting insulin (immunoreactive assay) and body fat mass (Bio-electric impedance) were measured. Insulin sensitivity was calculated using QUICKI.
Results: Diabetics had significantly higher mean of fat mass% than non-diabetics (26.55± 2.87% vs. 22.93±2.64 p< 0.05), despite fairly similar BMIs (27.7 kg/m2). Adiponectin concentration was lower in diabetics (7.77 ±3.53µg/ml) than non-diabetics (8.13 ± 0.03µg/ml) however, this difference was not statistically significant. The negative correlation between adiponcetin and fat mass didn't reach statistical significance. Adiponectin positively related with insulin sensitivity in non-diabetics (r= +0.5 p= 0.04).
Conclusion: Lower level of adiponcetin in diabetics than their non-diabetic counterparts. As well as the positive association of adiponectin with insulin sensitivity confirm the suggested role of decreased level of adiponectin in conditions such as insulin resistance and diabetes.

Abstract
Background: Leptin is a peptide strongly correlated with adiposity and is a potential determinant of obesity and its complications. The aim of this study was to evaluate the correlation between serum leptin levels and different anthropometric indices among obese women.
Methods: This analytical descriptive study consisted of 106 women with different grade of obesity (BMI ³ 25 kg/m2) and 38 women with normal weight (BMI ≤ 25 kg/m2).serum leptin and glucose levels were measured via enzyme immunoassay and glucose oxidase methods respectively.
Results: The mean (± SE) serum leptin concentrations in apparently healthy women with normal weight ,overweight, obese grade I, and obese grade II were 6.88 ± 0.56, 39.30 ± 1.73, 46.60 ±1.04, and 48.22± 3.31 ng/ml respectively. There was a dramatic increase in serum Leptin concentration when the BMI was increased. There was statistically significant differences between all groups in serum leptin concentration (P<0.001). There was a direct and significant correlation between serum leptin concentration and BMI in obese subjects (r= 0.736, P< 0.001). There was no significant correlation between leptin with age, and leptin with WHR neither in normal weight group nor in different grades of obesity groups.
Conclusion: Our findings showed that the serum leptin levels continuously raised with increasing degree of obesity and among different anthropometric indices serum leptin concentration has significant correlation with BMI.

Abstract
Background: Apelin increases insulin insensitivity but its correlation with exercise training has less been taken in to consideration. The aim of this paper was to evaluation the effect of combined (resistance, endurance) and endurance training on plasma Apelin and in insulin sensitivity.
Methods: Forty -five volunteered students of eligible (BMI: 25-30,Health and inactive) were randomly divided into three groups, combined, endurance and control.The trainedgroups were trained forfour days per week, during 12 weeks. In combined group, endurance interval training was performed fromfivereplication with three minutebeginningand in final weeks reached to thirteen replications of 3 minutes with resting time of 1 to 2minutes. Intensity was 60-80% HRmax and resistance training planning: 2days per week,7 stations(Boat,leg press,buttreflys, Knee extension and flexion, forearm flexion and extension) 8-12 replication, resting time between the intervals and sets consequently: 30-60 ,60-90 second . The endurance group was trained with the same endurance section of combined group. Pre and post weeks, plasma Apelin,glucose and lipid profiles were measured in groups. Data were analyzed by One Way - Anova,significant level was P&le0/05, using SPSS, ver 18.
Results: Plasma Apelin decreased significantly compared with the control group (P=0/0001).In training groups, HDL-c had in the training group increased compared with the control group (P= o/o43). Insulin Insensitivity wasn't different among groups (P&ge0/05).
Conclusion: This paper showed that 12 weeks of combined or Endurance training had significantly decreased plasma Apelin and both training groups had an increase in their HDL-c but all of the exchanges were free of insulin sensitivity.

Abstract
Background: kallikrein 7 (KLK7), a serine protease with a chymotrypsin-like specificity, is able to cleave human insulin in the A- and B-chain. The aim of this study was to investigate the effects of aerobic exercise training on plasma KLK7 concentration and insulin resistance index (HOMA-IR) in normal and overweight sedentary women.
Methods: Twenty-eight sedentary women, aged 24-60 years, voluntary participated in this study and according to body mass index status divided into normal (n=15) and overweight (n=13) groups. All subjects completed an 8-week progressive aerobic exercise training program (running with 40- 80% Heart rate reserve). Metabolic and Anthropometric (body weight, BMI, body fat percentage) parameters in addition to plasma KLK7 concentrations were measured at baseline and end of training program.
Results: Body fat percentage significantly decreased (P<0.05) and maximum oxygen consumption increased (P<0.05) by this training program in both training groups. At baseline, plasma KLK7 concentration in overweight women was significantly higher compared with normal weight group (P<0.05). Plasma KLK7 concentrations significantly increased after 8-week aerobic exercise training only in normal weight group (P<0.05). Changes in plasma KLK7 concentrations were not correlated with changes in insulin concentration and insulin resistance index (P<0.05).
Conclusion: Aerobic exercise training could be an effective factor to increase plasma KLK7 concentration in sedentary women. These data do not support a role of plasma KLK7 in insulin resistance alterations.

Abstract
Background: Omentin-1 is recognized as new Adipokine that mostly is excreted from visceral fatty tissue. Circulating levels of Omentin-1 are inversely associated with obesity. The aim of the present study on two training methods of endurance and resistance on Omentin-1 levels of plasma and factors related to obesity and overweight in obese girls, respectively.
Methods: Thirty four obese and overweight girls (BMI>25) were chosen purposefully then they were categorized at random to three endurance group (n=12), resistance group (n=12) and control (n=10). A total of 8 weeks of endurance and resistance training and endurance training was 4 times a week with 65 to 80 percent of HRmax and intensity resistance training was 65-80% of 1RM. Phlebotomizing was done at various stages with similar conditions and plasma Omentin-1 levels by ELISA method was measured. Data were analyzed by Kolmogorov-Smirnov and related t tests for studying the changes within the ANOVA and LSD post Hoc test for comparison between groups at the significance level of p<0.05.
Results: The results showed a significant increase Omentin-1 in both the experimental group (p endurance =0.001, p resistance =0.004) and reduce factors associated with obesity such as weight (p endurance =0.003, p resistance =0.005), fat mass body (p endurance =0.001, p resistance =0.001), BMI (p endurance =0.002, p resistance =0.004) and WHR (p endurance =0.011, p resistance =0.013) in both experimental groups after 8 weeks of training (p<0.05).
Conclusion: It can be stated that both endurance and resistance practices after 8 weeks of training, to improve factors related to obesity, maximal oxygen uptake and increased plasma levels Omentin-1 was.

Abstract
Background: Exercise interventions can play an important role in improving metabolic status by regulating hepotokines. The present study aimed to investigate the effect of eight weeks of Jump Rope Interval Training on serum levels of Fetuin-A and insulin resistance in overweight and obese young men.
Methods: In this semi-experimental study, 26 overweight and obese young men (body mass index: 28.24±1.66) were voluntarily and purposefully selected as a statistical sample and randomly divided into two experimental (n= 13) and control (n= 13) groups. The participants of the experimental group performed Jump Rope Interval Training for 8 weeks (four sessions per week/40 minutes each session). At the beginning and end of the study, venous blood samples were collected to measure Fetuin-A and insulin resistance. Data analysis was done using SPSS software version 24 and with dependent and independent t-tests at a significance level of less than 0.05.
Results: After 8 weeks of Jump Rope Interval Training, a significant decrease was observed in serum levels of Fetuin-A, insulin resistance and, body fat percentage (P≤ 0.05). Also, a significant difference was observed between the experimental and control groups in serum levels of Fetuin-A, insulin resistance and, body fat percentage (P≤ 0.05).
Conclusion: According to the results of the present study, it seems that regular jump rope interval training for eight weeks can effectively improve the metabolic complications in overweight and obese young men by reducing the serum levels of hepotokine Fetuin-A.

Abstract
Background: The present study aimed to investigate the effectiveness of Compassion-Focused Mindfulness Training on social isolation, sense of coherence, and body appreciation in overweight girls.
Methods: This study employed a quasi-experimental design with a pre-test/post-test control group. The statistical population consisted of overweight girls aged 14 to 18 in the city of Sari during the 2024-2025 academic year. A sample of 32 participants was selected via purposive sampling and then randomly assigned to either an experimental or a control group. The experimental group received Compassion-Focused Mindfulness Training, delivered in eight structured sessions, while the control group received no intervention. The Compassion-Focused Mindfulness protocol was developed and administered based on the therapeutic framework proposed by Sadeghi et al. (2021), the instruments used in this study included: the Body Appreciation Questionnaire by Mendelson et al. (2001), the Sense of Coherence Scale by Antonovsky (1987), the Social Isolation Questionnaire by Madrasi Yazdi et al. (2017), the collected data were analyzed using both descriptive and inferential statistics. Univariate and multivariate analysis of covariance (ANCOVA & MANCOVA) were performed using SPSS software, version 26.
Results: The results indicated that Compassion-Focused Mindfulness Training had a significant effect on self-worth, sense of coherence, and social isolation in overweight girls. Specifically, this training led to a reduction in social isolation and an improvement in self-worth and sense of coherence among the participants. (Wilks' Lambda = 0.151, F = 11.787, P< 0.001).
Conclusion: Compassion-Focused Mindfulness Training, by emphasizing the non-judgmental acceptance of experiences and fostering a meaning-centered approach, can play a vital role in enhancing psychological well-being, regulating emotions, and improving social interactions. Therefore, incorporating this effective intervention for vulnerable groups, particularly overweight girls, is crucial for designing supportive and therapeutic strategies and can significantly contribute to improving their quality of life.
