Abstract
Introduction: Anthropometric studies are particularly important among children and adolescents which monitor growth changes. Anthropometric studies indicate their health status.
Methods: This cross sectional study was about 1552 girls and 1551 boys with middle age, 11.5 years, were selected by random cluster sampling from first secondary students of Tabriz city. In this study their height and weight as well as BMI were evaluated. Data’s analyzed with softwares Epi Info, Anthro WHO, spss 16 and nutritional status assessed with WHO 2007 and CDC 2000 standards.
Results: As compared with WHO 2007 standard, 1.8% and 0.8 % girls and boys were short stature, 3.8% and 2.2% were thin, 0.5% and 0.8% were severe thin respectively. 8.7% and 14.5% were obese and 20.5% and 21.7% were overweight. Difference between BMI and height of girls and boys was significant with (P=0.0001) and (P=0.002) respectively. With CDC 2000 standard, respectively 0.1% and 0.3% girls and boys were severe underweight, 2.3% and 1.8% were moderate underweight, 13.7% and 13% were mild underweight. As well as 1.2% and 0.8% were short stature and BMI of them revealed 2.8% and 4.4% obesity, 20.5% and 24.7% overweight, 3.7% and 2.2% thinness, 0.5% and 1% of girls and boys were sever thin, respectively .Difference between BMI of girls and boys was significant. (P=0.002)
Conclusion: Different types of malnutrition in adolescents of Tabriz city are prevalent. Mention of standard name in assessment of malnutrition and obesity is necessary. WHO 2007 is valid standard to assessment nutritional status of children and adolescents. Using CDC 2000 standard underestimates obesity.

Abstract
Background: Life style changes have been considered in different ways in urban communities. Apartment housing, lack of physical activities, both parents being employed, entertainment devices relying on monitor display screens being within reach, leads our children to a sedentary life style. Obesity is just one of the side effects of this kind of living while children's confrontation with computer is decreasing to a lower age. There have been lots of surveys related to the duration of time spending on these entertainments with high school students but no research have been carried out on elementary school students in Iran. Methods: This cross-sectional study was carried on a sample of 450 male and female students attending the assessment center to register in the first grade in Karaj city. Results & conclusion: Therefore, in this survey, the average time new comers spent in front of a monitor screen was taken into account .The result showed that some part of child's daily activities was allocated to electronic devices having a monitor screen. Our findings showed that the allocated time for watching TV was 2.6 hours per day, for satellite programs: 0.49 hours per day, for Computer operating: 0.9 hours per day, Computer games: 0.38, and play station: 0.14hours per day and in total they used electronic devices 4.6 hour per day. Moreover, in this study, the BMI of each case has been calculated and the spread rate of weigh disorders was studied. About the weight disorders, we found that 15.8 % of students in this survey were low weight, 69.8 % were in normal ranges, 8.9 % were overweight and 5.4% were obese. In this survey, the relation between weight disorder and the rate of using electronic monitor screens was also studied. however, we couldn’t find any relevance between the two variables, probably the weight disorders must be affected by many other factors. We considered demographic variables as well as other variables which may affect weight disorder.

Abstract
In this study we answer this main question: what extent genetic and environmental factors affect children obesity?
Research methodology in this article is a survey method. For data collection, 384 children between 6-12 years old have been randomly selected from girl’s and boy’s primary schools in Qom city. Descriptive and inferential statistics are used for analysis.
Findings show that 19% of children under study are overweight and 13.2% are obese and remaining has normal weight.
Overweight and obesity is observed more in boys than girls, also this study shows that there is a significant relationship between genders, physical activity, fast food consumption, sleep debt, parental BMI and rate of the prevalence of childhood obesity, but there is not a significant relationship between age, family income and mother education level.
So some effective factors that can be controlled must be considered like food type, physical activity and quality and quantity of children’s sleep and necessary actions must be taken under planning two main factors.

Abstract
Background: Dental caries is considered as the most common chronic disease and a major health problem in developing countries. Excessive consumption of carbohydrates is one of the most important causes of dental caries as well as obesity. The aim of this study was investigating dental caries (based on DMFT index) and its relation with body mass index (BMI) among students of Alborz University in 2018-2019.
Methods: In this cross-sectional study, 382 students were choosed by a Quota sampling. Demographic information, dietary, nutrition and hygenic habits were recorded by a questionnaire. Then clinical examination was performed concidering oral health status and DMFT. Also BMI of the participants was calculated by measuring the height and weight of each student. SPSS-19 software was applied for data analysis.
Results: Overal 38.2% of the students were male (20.56 ± 1.9 years old) and 61.8% were female (20.59 ± 2.2 years old). The mean of DMFT and BMI of the participants was 6.6 ± 3. 3 teeth and 22.7 ± 3.2 kg/m2 respectively. In all, 0.3% had severe low weight, 8.4% low weight, 68.6% normal, 20.4% overweight, 2.1% class-I obesity and 0.3% class-II obesity. Relationship between DMFT and BMI was not significant (P=0.299).
Conclusion: In this study no significant relationship was noticed between DMFT and BMI, which indicates that these two indexes are independent of each other

Abstract
Background: Iodine deficiency disorders (IDD) are the most important epidemic disorders in the world. In the last two decades, the elimination of IDD has been considered as an integral part of many national nutrition strategies. The aim of current research was to determine the urinary iodine and its related factors in elementary students of Alborz province.
Methods: In a cross sectional study 240 students of both genders, aged from 8-10 years were selected from urban and rural area of Alborz province were selected by cluster sampling method. Participants' urine was collected, and urinary iodine was measured. Information on nutrients intake was collected by a 24-hour feed recall method. Questionnaires on general data and anthropometric measurements (height, weight, BMI) were performed by a nutritionist. Significance level (p value <0.05) was considered.
Results: Of 240 participants, including 118 girls and 110 men, only 37% were in normal condition. 20% of students had iodine deficiency and 43% had excessive urinary iodine. The mean urinary iodine was not significantly different between the two groups. There was a weak but significant relationship between time of cooking and mean urinary iodine. Correlation between BMI and mean urinary iodine showed a weak negative correlation, which was statistically significant (p <0.02).
Conclusion: The prevalence of iodine-related disorders (high and iodine deficiency) has increased in recent years in Alborz province. Modification of iodine salt consumption pattern and BMI seems to be effective in reducing disorders.
