Abstract
Background and Aim: Body mass index (BMI) is the most useful index used to screen children obesity. Since height and weight are determined by genetic, racial and environmental factors, body mass index can differ from one population to another. The aim of this study was to prepare the normogram of (7-120year old) children body mass index (BMI) in Birjand and to compare it with that of with the center of disease control (CDC).
Materials and Methods: This cross-sectional, descriptive, analytic study was performed in 2002 on 1928 primary school students, including 1010 boys and 918 girls, who were selected through two- stage sampling (cluster and systematic). Their height and weight were measured. Body mass index (BMI) was defined as weight- Kg / Height-m2. The relevant percentiles of BMI for sex and age were established and compared with CDC percentiles.
Findings: The BMI percentiles of 7-12 year old children in Birjand were significantly lower than CDC. Mean percentile of BMI among girls of most age groups under study was 10-25 percentiles of the CDC and below 10 percentile of CDC for boys.
Conclusion: Regarding the results of this study which is much below CDC, there is a difference between CDC normograms and BMI of Birjand children. This difference can be attributed to racial differences and some environmental factors. It is recommended that the regional normograms should be developed through more comprehensive studies, so that they could be used for the assessment of weight disorders among Iranian children.

Abstract
Background and Aim: Cataract is one of the public health problems worldwide and it is the most important cause of blindness. The aim of this study was to evaluate some risk factors of cataract including history of hypertension, body mass index (BMI), smoking, literacy, and type of job in the patients.
Materials and Methods: This case-control study was implemented on 176 patients with cataract (case group) and 176 healthy volunteers (control group) of referrals to Birjand Valiassr hospital. A general questionnaire was used to collect the information about history of hypertension, smoking, type of job and
education level. Case and control groups were matched by age and sex. Blood pressure, length and weight of patients were determined. Then data entered to SPSS software and analyzed with chi-square and regression logistic at α=0.05.
Results: History of hypertension was recorded in 29.5% of the cases and in 19.3% of the control group (P=0.026). In terms of education, 88.1% were illiterate in the case group and 64.2% in the control group (P<0.001). Job title with significant difference included only farmers (35.2% in the case group and 22.2% in the control group; P<0.001). Smoking was observed in 18.8% of the cases and in 10.8% of the controls (P<0.001), were higher in case groups then control group; But body mass index (BMI) was higher in control group (6.8% in the case group and 16.5% in the control group) (P<0.001).
Conclusion: The results of this study showed that hypertension; smoking and low literacy are the risk factors for Cataract. These findings indicate a need for health promotion activities to control these risk factors.

Abstract
Background and Aim: Considering the importance of obesity and regarding that only few studies in the field of normal anthropometrics are available in the country, the present .study was conducted to survey cardiovascular diseases (CVD) risk factors in people with normal body mass index and waste circumference. Materials and Methods: Data of this cross-sectional study was obtained from the 1st phase of Isfahan Healthy Heart Program (IHHP), which is a communo-intervening plan on 3718 individuals aged over 19 years, having normal Body Mass Index (BMI) and waist circumference (WC) in Isfahan, Najaf-abad, and Arak. In order to evaluate the association between the quartiles of BMI and WC with CVD risk factors, multiple logistic regression was applied. Results: Out of the population of the study, 2859 were males and 859 females with mean age 34.29±14.29 yrs. The odd ratio (ORs) of dislipidemia in the biggest quartile of BMI in males and females was 1.84 [1.45-2.33] (P<0.001) and 1.56[1.05-2.30] (P<0.05), respectively. Odds ratio of at least two risk factors in the highest W.C. quartile was 2/6 [1.45-4.65] (P=0/001). and In men, the odds ratio of at least one risk factor in the highest WC and BMI quartile were 1.42 [1.12-1.817] (P=0.001) and 1.78[1.90-2.27] (P=0.002), respectively compared with the first quartile. Conclusion: Although normal borderline levels of BMI and WC are used to predict CVD risk factors, but lower borderline levels of these Indexes can also be referred to as a CVD risk predictor.

Abstract
Background and Aim: The aim of the current study was to determine prevalence of obesity and overweight in 2-5 year olds and its association with parental obesity in Birjand. Materials and Methods: This descriptive - analytical study was conducted on five hundred2-5 year olds of Birjand kindergartens and their parents in 2009. Height, weight, and BMI of the subjects were measured using standard methods. In the children, BMI of 85-95 percentile were taken as overweight and BMI≥95 percentile for age and sex were accounted as obese .Regarding parents, BMI of 25 - 29 were considered as overweight and BMI≥30 as obesity. The obtained data was analyzed by means of SPSS software (V: 13) at the significant level of α=0.05. Results: Prevalence of obesity in children was 7.6% (6.3% in girls, 8.8% in boys) and that of overweight was 10.6% (11.7% in girls, 9.6% in boys). Out of all fathers and mothers, 44.2% and 30.2% were overweight, respectively and also 7.8% of fathers and 6.8 of mothers were obese. Prevalence of overweight and obesity in children of mothers with normal BMI were 15%, but in those having overweight and obese mothers it was 24%. This prevalence was 15.4% in children with normal BMI fathers and in children having overweight and obese fathers it was 20.8%. It was found that there was a significant positive association between children’s BMI and that of their parents (r=0.11, r=0.12, P<0.05). Conclusion: Given the significant and positive correlation between children's and their parents’ obesity, it is important to educate Families to improve their eating patterns and life styles for weight control in their children, particularly in those having obese members.

Abstract
Background and Aim: The pomegranate fruit peel has been suggested in traditional medicine as an anti-obesity compound. Therefore, the study was carried out to evaluate the effects of aqueous or ethanolic extracts of pomegranate fruit peel on obesity and lipid profile in rat. Materials and Methods: In this experimental study, 24 Wistar male rats randomly divided into 4 equal groups (2 experimentals and 2 controls). The experimental groups A and E treated with aqueous or ethanolic extract of pomegranate peel at dose of 400 mg/kg, respectively, for 35 days. The control groups N and X respectively received 5mg/kg of saline and Xenical during the study as same as the experimental groups. The rats' weight, body mass index (BMI) and waist circumference were determined before and after investigation. Also at the end of study plasma lipid profile were measured. All data were analyzed by Prism software (ver- 3) and using paired samples t-test and ANOVA. Results: Comparison of weight change before and after the intervention showed a significant reduction in the Group E and a significant increase in group N (p≤0.05). Waist circumference was significantly increased in the experimental group A and control group N (p≤0.05) and reduced in group X (p≤0.05).There was no significant difference in plasma lipid profile between the groups. Conclusion: The ethanolic extract of pomegranate fruit peel can be considered as an anti-obesity compound in further studies.

Abstract
Background and Aims: Physical health is an important aspect of the health of any society and one of the most basic needs of human life. The present study aimed to investigate the effect of body mass index and level of physical activity on motor competence in women within the age range of 8-85 years in Tehran, Iran.
Materials and Methods: The present cross-sectional study was performed on 323 women aged 8-85 years who were divided into five groups, namely children, adolescents, young women, adults, and the elderly. The participants were selected using the convenience sampling method, and the required data were collected using a weight gauge, a height gauge, the short form of the International Physical Activity Questionnaire, and a motor competence test. The collected data were analyzed using multivariate one-factor analysis of variance and Bonferroni test.
Results: The results of multivariate one-factor analysis of variance showed that the body mass index had no significant effect on motor competence (P<0.05). The main effect level of physical activity and age group on motor competence variable was significant (P=0.001). Performance of the children group was significantly weaker than that of young women regarding motor competence (P<0.05). Moreover, the performance of female children was better than that of the elderly group in terms of the motor fitness variable. In addition, the elderly group had lower motor competence, compared to children and adolescents. Besides, people with a moderate level of physical activity performed significantly better in the motor competence test than those with low and intense levels of physical activity (P<0.05).
Conclusion: The level of physical activity should appropriately increase to enhance motor competence and physical health. Furthermore, the downward trend of motor competence can be delayed by the adoption of proper plans.

Abstract
Background and Aims: Adipolin is an anti-inflammatory adipokine that plays a role in insulin resistance. This study aimed to examine the changes in plasma levels of adipolin and some body composition indices in overweight and obese women following eight weeks of intense interval training.
Materials and Methods: This quasi-experimental and applied study was performed on 30 subjects who were purposefully selected and randomly divided into two experimental and control groups (n=15). The intense interval-training program consisted of running for four minutes at an intensity of 45-60% of maximum heart rate. The first training session was performed at 45% of maximum heart rate, and gradually the intensity of the training was increased by 5% each week. After reaching an intensity of 60% of the heart rate, it was maintained until the end. Blood sampling was performed after 12 h of fasting in two stages, before and after the test, and the research variables were measured. Data were analyzed in SPSS software (version 24). For intra- and inter-group changes, dependent t-test and independent t-test were used at a significance level of P≤0.05.
Results: According to the independent t-test, the values of adipolin, body mass index, body weight, and waist to hip ratio in the experimental group were significantly different from those in the control group (P<0.05). Moreover, according to the dependent t-test, the values of adipolin increased significantly after eight weeks of training, but body weight, BMI, and WHR decreased significantly (P<0.05).
Conclusion: In conclusion, regarding the increase in adipolin and the decrease in some body composition indices, it is recommended that overweight and obese individuals use high-intensity interval training methods to prevent obesity-related diseases.
