Mental health problems including emotional and behavioral problems during puberty may be under influence of different risk factors including cultures, living in urban or rural areas and ethnic factors which may vary between different countries. The main aim of this study is to investigate the profile of emotional and behavioral problems and the role of factors such as age, stage of puberty, ethnicity, rurality and living in urban area, as risk factors in Iranian girls. As a part of a large national study we evaluated the emotional and behavioral problems in different stages of puberty in a community sample of Iranian adolescent girls from public schools that were selected by clustered random sampling method.

This national survey was conducted on 4811 representative school-students. We assessed the sensitivity and specificity of the HW phenotype for abnormal anthropometric and biochemical factors by using receiver operator characteristic curves.

Design: This cross-sectional study is the baseline survey of a national longitudinal study. SUBJECT/SETTING: Overall 4,811 nationally representative children, aged 6 to 18 years, were recruited from the community through randomly selected schools within six provinces in Iran.
Background And Aim: To date, research on the influence of environmental factors on metabolic syndrome (MS) among youths is limited. This study was conducted to investigate for the first time the association of these factors with MS in a large national, representative sample of children from a non-Western population.
Methods And Results: The study population comprised of 4811 students (2248 boys and 2563 girls) aged 6-18 years, living in six different provinces in Iran.
Aims: To assess the results of factor analysis of coronary artery disease risk factors in a large national representative sample of children, and to compare its results on the variables measured between those with or without metabolic syndrome (MetS).
Methods: This cross-sectional multicenter population survey was conducted on 4,811 nationally representative school students aged 6-18 years. MetS was defined based on criteria analogous to the Adult Treatment Panel III.
The Objective of the present study is to develop the first age- and gender-specific reference curves for waist and hip circumferences in an Asian population of youths. This cross-sectional population survey was conducted in 2003-04 on a nationally representative sample of 21111 school-students living in urban (84.6%) and rural (15.

Objective: To examine the relation of dietary and physical activity (PA) patterns with the body mass index (BMI), and the associations between these patterns among children.
Methods: A representative sample of 21 111 school students aged 6-18 years was selected by multistage random cluster sampling from 23 provinces in the Islamic Republic of Iran. PA and dietary pattern were assessed by self-administered validated questionnaires.
Background: This study was performed to determine the blood pressure (BP) percentile curves by height, as well as to assess the prevalence of high BP and its influencing factors among children in the first national survey in this field in Iran.
Design: A multicentre national cross-sectional survey.
Methods: This study was performed in 23 provinces among a representative sample of 21,111 students aged 6-18 years.
Background/aim: To determine the association of physical activity and the metabolic syndrome in a large national-representative sample of children.
Methods: This study was performed in 2003-2004 on 4,811 school students aged 6-18 years, selected by multi-stage random cluster sampling from six provinces in Iran. We assessed the level of physical activity using a standardized questionnaire, and categorized it to the tertiles.
Background: For the first time in Iran, and to the best of our knowledge in Asia, we assessed the anthropometric indices most closely correlated to cardiovascular disease (CVD) risk factors in a large nationally representative sample of children and adolescents to be used as a simple tool for identifying those at risk.
Methods: This multi-center study was performed among a representative sample of 4811 school students (2248 boys and 2563 girls) aged 6-18 years, as part of the baseline survey of a national surveillance system. Anthropometric indices and CVD risk factors were measured using standard protocols, and their correlation was analyzed by using Receiver Operator Characteristic (ROC) curves and partial correlation.
Objectives: To determine the national prevalence of smoking among Iranian youths and its environmental influencing factors.
Methods: This study was performed in 2003-2004 among 11,966 school students, ages 11-18 years, selected by multi-stage random cluster sampling from 20 provinces in Iran. The participants filled out self-administered anonymous questionnaires.
