Abstract
Background: Non-alcoholic fatty liver disease is among the prevalent causes of chronic hepatitis and cirrhosis. Here, we discuss the best diagnostic and therapeutic approaches for the disease. Materials and Methods: Epidemiology, pathogenesis, etiologies, natural course, differential diagnosis, treatment options, complications and follow up of the disease are reviewed in this paper. Results: Non-alcoholic fatty liver disease seems to be the hepatic manifestation of the metabolic syndrome. Liver function tests and sonography can be used as the appropriate screening tests for diagnosis. Weight loss and control of hyperlipidemia and diabetes mellitus might be the best therapeutic approaches. Conclusion: Early diagnosis and appropriate treatment may decrease mortality and morbidity rate associated to the cardiovascular complications of the metabolic syndrome.

Abstract
Background: An increase in the prevalence of metabolic syndrome (MetS) and type 2 diabetes (T2D) among the obese children is associated with such complications as the early cardiovascular diseases. This study was undertaken to evaluate the frequency of MetS and T2D among the obese children and adolescents in Kashan. Materials and Methods: This cross-sectional study was carried out on 450 obese children aged 4-18 years in Kashan. Demographic data were recorded for each case and the 12-hour fasting blood samples were collected to determine the total cholesterol, HDL, triglyceride, and plasma glucose levels. MetS was defined as the presence of at least three of the following five criteria: (1) BMI≥95th percentile for age and gender, (2) triglyceride level >95th percentile for age and gender, (3) HDL level<5th percentile for age and gender, (4) impaired fasting glucose≥100 mg/dL, and (5) systolic or diastolic blood pressure≥95th percentile for age and height. Results: Among 450 children, 227 (50.4%) cases were male and 223 (49.6%) female. The mean age of children was 10.3±3.18 years. One hundred fifty-four cases (34.22%) had MetS and 7 cases (1.3%) met 5 criteria for MetS. Moreover, three cases (0.7%) had T2D. Conclusion: Significantly high frequency of the metabolic syndrome in obese children and adolescents in this city can signal a wide range of adverse health effects.

Abstract
Background: Obesity and its related disorders are the cause of cardiovascular disease and an increased risk of morbidity and mortality. Nevertheless, the results of studies indicated that exercise training have beneficial health effects on obesity and risk markers of cardiovascular disease. Therefore, the purpose of this study was to examine the effect of 8 weeks of resistance training on lipocalin2 (LCN2) and fatty acid binding protein (FABP) in obese adult males.
Materials and Methods: In this quasi-experimental study, the obese adult men (n=24) were randomly assigned into Control and Exercise groups. Exercise group was participated in a resistance exercise program with 50-80% of one Repeated- Maximum (IRM) intensity for 8 weeks (three times per week). Venous blood samples were collected before and after the exercise. Moreover, body composition indexes were measured at pre- and post-training programme
Results: Resistance exercise caused a significant decrease in the body fat percent, waist circumference and waist to hip ratio (WHR) in Exercise group (P<0.05). Moreover, the results indicated a significant decrease in Exercise group for LCN2 concentration after resistance training (P=0.002) compared to Control group (P=0.799). Also a significant decrease in FABP4 concentration was found in Exercise group (P=0.002).
Conclusion: The results of the present study suggest that 8 weeks of resistance exercise improve body composition and decrease the new cardiovascular biomarkers in obese men. However, further research is necessary to understand the molecular mechanisms involved.

Abstract
Background: The present study conducted to evaluate the frequency of cardiovascular risk factors in patients with osteoarthritis compared to those without osteoarthritis.
Materials and Methods: A cross-sectional study was conducted in a university-affiliated hospital in 2017. Using the convenience sampling method, 100 patients based on their symptoms, physical examination and radiographic findings were selected for the osteoarthritis group, and 100 persons with muscular disease or fracture for the control group. Frequency rates of gender, diabetes mellitus, hypertension, hypercholesterolemia, body mass index, metabolic syndrome and waist circumference were evaluated.
Results: Frequency rates of female gender, hyperlipidemia, metabolic syndrome were significantly higher in the osteoarthritis group compared to the group without osteoarthritis (P<0.05). The mean of waist circumference in the osteoarthritis group was significantly higher than that in the control group (P<0.05). There was a significant relationship between osteoarthritis and female gender (OR=2.45, P=0.006), metabolic syndrome (OR=1.85, P=0.03), hypercholesterolemia (OR=1.77, P=0.04), waist circumference (OR=1.3, P=0.025) and smoking (OR=0.35, P=0.014). The associations of metabolic syndrome, hypercholesterolemia and waist circumference with osteoarthritis remained significant after adjusting with sex.
Conclusion: Finding of the present study may indicate the relationship between osteoarthritis and metabolic syndrome, hypercholesterolemia and central obesity.

Abstract
Background: This study aimed to determine the effect of 8 weeks of resistance training using elastic bands and green coffee supplement on hepatic steatosis index in obese middle-aged Women.
Materials and Methods: In this randomized clinical trial, 60 obese (33.58±2.96) and middle-aged women (42.99±3.08) were selected as the subjects and were randomly divided into four groups of 15 people: supplement, exercise+supplement, exercise+placebo and placebo. The training groups received eight-week elastic band resistance training program at 3 sessions per week and 60 minutes each session. Daily supplementary groups received a 400 mg capsule of green coffee extract. Blood samples were measured 24 hours before the start and 48 hours after the end of the protocol in the fasting state. In order to compare intra-group and extra-group, the t-test and the two-way ANOVA and post-hoc Bonferroni test were used.
Results: The results showed that 8 weeks of exercise with supplementation, despite significantly reducing the serum levels of liver enzymes in the experimental groups, there had no significant difference with the control group. Also, 8 weeks of resistance training combined with green coffee supplementation made a significant difference in the index of hepatic steatosis in obese women.
Conclusion: However training with elastic bands and green coffee consumption improved hepatic steatosis index but considering that its effect on liver enzymes was not significant. it seems, improvement in liver function indices in obese women may require longer periods of resistance training and green coffee supplementation.

Abstract
Background: CTRP-3 is a relatively new anti-inflammatory adipokines that is involved in the metabolism of the body, liver and adipose tissue. However, effects of spinning exercise and stationary bike on serum level of CTRP3 and body fat percentage have not been understood.
Materials and Methods: In this quasi-experimental study, forty-five obese and overweight women with body mass indexes above 25 kg/m2 were divided into three groups of 15 people: control, spinning exercise and stationary bike. Subjects performed the exercises for 6 weeks and three sessions each week. The Spinning exercise group Includes pedaling a bicycle with music and stationary bike group performed the exercise individually by pedaling on a stationary bike. Blood sampling and measurement of body composition indices were analyzed 24 hours before and 48 hours after last training session. In addition, intra group changes was performed using dependent t-test, for between group changes covariance analysis was used after determining pre assumption tests, then to locate the differences LSD follow-up test at a significant level (P<0.05) was performed.
Results: Serum CTRP-3 levels increased significantly about 28% in spinning group (P=0.012) and about 20% in stationary bike group (P=0.021) while body fat percentage decreased 6% in spinning group (P=0.001) and 4% in stationary bike group (P=0.001) after 6 weeks. There were significant differences between two studied groups in serum levels of CTRP-3 (P=0.015) and body fat percentage (P=0.001). Changes were not significant in control group.
Conclusion: It seems that spinning and stationary bike training effective strategies in preventing metabolic diseases through increasing CTRP-3, the anti-inflammatory marker, can be involved in body's metabolism, liver and adipose tissue.

Abstract
Background: One of the effective ways to control weight is to use regular exercise and benefit from herbal supplements. This study aimed to evaluate the changes in lipocalin-2 levels after resistance training (RC) and consumption of spirulina microalgae in overweight and obese men.
Materials and Methods: The present study was a single-blind, quasi-experimental and applied control clinical trial. 60 men with an age range of 30 to 55 years and a body mass index of more than 25 (kg/m2) overweight and obese, were purposefully selected and randomly selected (with alternatives) in four groups: Training + Spirulina, Training + Placebo, spirulina and placebo were included. The intervention and placebo groups took two 500 mg spirulina and placebo capsules daily for eight weeks, respectively. (RT) was performed for eight weeks, three sessions per week.
Results: Plasma lipocalin-2 and body weight showed a significant difference between the groups (P<0.05). Also, lipocalin-2 values in training + spirulina group and fat percentage in training + spirulina, training + placebo groups, decreased significantly. Pure and net body mass increased significantly in the training + spirulina group (P<0.05).
Conclusion: It seems that spirulina supplementation combined with (RT) can be effective in controlling weight and obesity by reducing the amount of lipocalin-2 and some indicators of body composition.

Abstract
Background: Endothelial dysfunction, caused by obesity, can be regarded as the initial step in the development of the cardiovascular disease. Hence, the current study aimed to the effects of HIIT exercises on miR-16 induced endothelial function, total antioxidant capacity (TAC) and serum malondialdehyde (MDA) in the obese men.
Materials and Methods: 24 obese male volunteers, with a mean age of 44 years and BMI>30, were randomly divided into the training and control groups. The eight-week HIIT training group did circular exercises, including (Long Knee, Butterfly, Burpy, kettlebell snatch, and Scott Goblet), with an intensity of 80-90 % of Karvonen heart rate (first four weeks: three sessions and second four weeks: four sessions per week). Blood samples were taken from the subjects 48 hours before and after the last training session to analyze miR-16, NO, serum MDA, and TAC indices of the subjects.
Results: Eight weeks of HIIT training in the training group caused a significant increase in NO and TAC values and a significant decrease in serum MDA compared to the pre-test values. (P<0.05). Furthermore, compared to the control group, a significant decrease in miR-16 and MDA levels was observed and a significant increase in serum NO and TAC was observed in the training group (P<0.05).
Conclusion: HIIT training apparently alter serum NO levels by affecting miR-16 levels and reducing oxidative stress caused by obesity and can prevent from outbreak and development of the cardiovascular disease by improving endothelial function.

Abstract
Background: The age of onset of obesity and its consequences have decreased, this study aimed to compare the effect of 12 weeks of aerobic activity with light and heavy intensities on fat burning in obese and overweight children.
Materials and Methods: The statistical sample of this quasi-experimental study included 30 primary school male students with overweight and obesity (mean age 11±0.83 years and body mass index of 29.2±4.3 kg/m2). No diet control, they were randomly divided into three groups of light aerobic exercise (n=10), heavy aerobic exercise (n=10) and control (n=10). 24 hours after the first stage of blood sampling and fat assessment, the experimental groups performed aerobic activity (outdoor walking) with two intensities of light (40-50% HRmax) and heavy (80-70% HRmax) for 12 weeks. The control group did not perform any continuous physical activity. At the end of the 12-weeks exercise program, blood samples and fat assessment values were collected. Data were analyzed using paired t-test, one-way analysis of variance and Post hoc Tukey test using SPSS-24 software at P≤0.05.
Results: The results showed that both light and heavy aerobic exercise protocols decreased cholesterol, fat triglyceride, and serum leptin, LDL, BMI and HDL. However, heavy intensity aerobic exercise was significantly more effective on the above variables.
Conclusion: It seems intense aerobic exercise has a greater effect on fat burning in obese children.

Abstract
Background: Teenage obesity is so important issue in health as it is a defining indicator of obesity in adulthood. The aim of this study was to investigate the effect of a dialectical behavioral therapy on emotion regulation, impulsivity and body mass index (BMI) in obese or overweight teenage girls.
Materials and Methods: The present study was a randomized clinical trial with pretest-posttest and control group. The study population included overweight and obese girl students (n=40) aged 13-15 years in Kashan, Iran, in the academic year of 2018-2019. The students were selected through target-based sampling, and randomly assigned into intervention and control groups. Participants completed emotion regulation and impulsivity questionnaires and their BMI was assessed. The intervention group underwent the dialectical behavior therapy, while the control group received no treatment.
Results: Dialectical behavior therapy significantly reduced the mean scores of difficulties in emotion regulation (F=7.36, P<0.01) and BMI (F=9.15, P<0.001) compared to the control group. However, the mean score of impulsivity in the treatment group did not decrease significantly (F=1.52, P>0.05).
Conclusion: According to the current findings, the dialectical behavior therapy can be considered as an effective therapeutic approach to reduce the difficulty in emotion regulation and BMI in obese or overweight teenagers.

Abstract
Background: The aim of this review study was to compare the effect of high-intensity interval training (HIIT), and moderate-intensity continuous training (MICT) on cardiometabolic factors in children and teenagers with overweight and obesity.
Materials and Methods: A systematic search was conducted in PubMed, Web of Science, SID, Magiran, and Google Scholar databases for English and Persian articles published until December 2022. A meta-analysis was performed to compare the effect of HIIT and MICT on cardiometabolic factors (body fat percentage, free fat mass, maximum oxygen consumption, systolic blood pressure (SBP), and diastolic blood pressure (DBS) in children and teenagers with overweight and obesity.
Results: The results of 15 studies with 429 children and teenagers with overweight and obesity showed that HIIT caused a significant decrease in body fat percentage [WMD=-0.59, P=0.04], and SBP [WMD=-1.98, P=0.004]. In addition, the results showed that HIIT caused a significant increase in the maximum oxygen consumption [SMD=0.65, P=0.001], compared to MICT in children and teenagers with overweight and obesity. In contrast, HIIT causes a non-significant change in free fat mass [WMD=0.65, P=0.5], serum HDL [SMD=0.06, (CI: P=0.5], DBP [WMD=-0.6, P=0.7], and body weight [WMD=-0.33, P=0.7], compared to MICT in children and teenagers with overweight and obesity.
Conclusion: HIIT reduces body fat percentage and SBP, and increases maximum oxygen consumption, compared to MICT in children and teenagers with overweight and obesity. Therefore, HIIT is recommended as a non-drug solution to reduce cardiometabolic risk factors in children and teenagers with overweight and obesity.

Abstract
Background and Aim: The prevalence of obesity is one of the most important health issues in the world. The aim of this study was to determine the effect of intermittent resistance training with different intensities on the levels of interleukin-10 (IL-10) and interleukin-1 beta (IL-1β) in obese men.
Methods: In this study, 44 obese men (20-30 years old) were assigned into four groups of control, low-intensity intermittent resistance training, moderate-intensity intermittent resistance training, and high-intensity intermittent resistance training. Subjects trained for 12 weeks, 3 sessions per week with three different intensities (80% 1RM with 10 repetitions, 60% 1RM with 13 repetitions and 40% 1RM with 20 repetitions). IL-10 and IL-1β indices were measured 48 hours before the first and 48 hours after the last resistance training session.
Results: A significant difference was reported in IL-10 and IL-1β levels between the intermittent resistance training groups with different intensities. After the training period, IL-1β had a significant decrease in the low (P=0.001), moderate (P=0.01) and high (P=0.001) intensity intermittent resistance training groups. A significant increase in the IL-10 was observed in the resistance training groups with low (P=0.01), moderate (P=0.01) and high (P=0.001) intensity.
Conclusion: According to the present findings, it may recommend intermittent high and moderate intensity resistance training as an effective method for treating obesity and having a favorable effect on its indicators.
