Genetic and environmental factors are known to be related to the development of childhood Eczema. We aimed to assess the ecological factors associated with the prevalence of Eczema among children using the ISAAC questionnaire.

A total of 1600 primary school girls and boys were selected and examined by multistage random sampling in this cross-sectional study. Data were collected and completed using the International ISAAC Questionnaire, including demographic questions and risk factors through interviews with parents, especially the student’s mother. The data were analyzed in SPSS v. 19 software using the Chi-square test and multiple logistic regression.

This study was approved by the Ethics Committee of Zahedan University of Medical Sciences (Code: REC.1397.481).

 The prevalence of current Eczema was 10.4% (95%CI: 8.9-11.9). Co-morbidity with Asthma and Rhinitis was 82.8% and 74.5%, respectively. In multiple logistic regression models, history of allergies in family members (OR: 2.35, 95%CI: 1.53-3.59), father snoring (OR: 3.00, CI95%: 1.98-4.55), Keeping any animal in (OR: 1.6, 95%CI: 1.002-2.58), family size (OR: 0.85, 95%CI: 0.68-0.95), exposure to tobacco smoke at home (OR: 2.84, 95%CI: 1.18-6.81), showed a significant relationship with the occurrence of students’ Eczema.

 Exposure to tobacco smoke at home, keeping any animal at home are effective factors in the prevalence of Eczema in children. By eliminating these factors, the prevalence of this disease can be reduced. However, the mothers have the most crucial role in screening and early diagnosis of Eczema in school children regarding determinants in this study. According to the results of this study, it is suggested that parents’ education, especially mothers, be emphasized by paying attention to these favorable factors.

The prevalence of Allergy Rhinitis (AR) has increased dramatically among children. The aim of this study was to determine the prevalence of AR symptoms among school‐age children in Zahedan, southeast of Iran.

In this cross-sectional study, 1600 primary school girls and boys were selected and examined by multistage random sampling. Data were collected and completed using the International ISAAC (International Study of Asthma and Allergies in Childhood) questionnaire including demographic questions and risk factors through interviews with parents, especially the studentchr('39')s mother. The data were analyzed in SPSS19 software using chi-square test and multiple logistic regression.

The prevalence of current AR and Rhinoconjunctivitis among elementary school Children was 15.3% and 10.2% respectively. The prevalence of current AR was not statistically significant in girls with 14.2% and boys with 16.4% (p>0.05). Co-morbidity with asthma and eczema was 27.3% and 28%, respectively. The occurrence of AR was related to BMI, family size, snoring father, type of heating and cooking (p<0.05).

The prevalence of AR in Zahedan is relatively high due to the special climatic conditions and geographical climate of the region. Overweight in students and the use of fire for cooking and heating the house is an effective factor in the prevalence of AR in children, which can be eliminated by reducing the prevalence of this disease. However, the mothers have most important role in screening and early diagnosis of AR in school children regarding determinants in this study.

Asthma and allergic diseases are raised as a major health problem. The prevalence of these diseases are increasing in Iran and all over the world. Based on this, the present study assessed to prevalence of these diseases in Assalouyeh region, Bushehr Province.
Material and This study was performed on 190 school children aged 6-7 years and 223 girl student aged 13-14 years in Assalouyeh city in 2014 based on ISAAC standard questionnaires Phase I and III which examined prevalence and risk factors for these diseases.
The prevalence of atopic eczema, allergic rhinitis and asthma among 6-7 year-old students were 11.6%, 13.7% and 5.8%, respectively. While, the prevalence of these diseases among 13-14 year-old students were 14.3%, 21.5% and 15.2%, respectively. Also, there were a significant association between risk factors such as exposure to tobacco smoke, pet keeping, consumption of fast and sea foods with prevalence of these diseases (P Asthma and allergic diseases were high among school children in Assalouyeh and it seems that this increasing prevalenc can be associated with risk factors such as exposure to tobacco smoke, pet keeping, consumption of fast and sea foods.

Asthma and allergic diseases are raised as a major health problem in the world. The prevalence of these diseases is on the rise specifically in the world and Iran. Accordingly, the aim of this study was to assess the prevalence of these diseases in Jam City, from environs of Bushehr Province.
Material and this study was performed on 516 schoolchildren aged 6-7 years and 569 schoolchildren aged 13-14 years in schools of this city based on a standard questionnaire of allergic conditions and asthma (ISAAC) phase 1 and 3, which mention to the prevalence and risk factors for these diseases in 2014.
in prevalence of atopic eczema, allergic rhinitis and asthma among 6-7year old schoolchildren were 13.8 %, 20% and 3.9%, respectively, While, the prevalence of these diseases among 13-14 year old schoolchildren were 19.5%, 19.2% and 6.7%, respectively. There were a significant association in each group, between affliction rate to asthmaand its association with rhinitis and eczema (P the prevalence of asthma and allergic diseases was high in Jam city and this increase is associated to risk factors such as exposure to cigarette smoke, pet care and use of gas as a fuel at home.

International study on asthma was conducted to study the prevalence of Asthma symptoms among 13-14 year old children using written and video questionnaires during the early 90's. The aim of the present study (ISAAC) was to evaluate the agreement between the two questionnaires which were self-completed by the children.

This study, which was a part of the third phase of International Study of Asthma and Allergy in Childhood (ISAAC) and performed exactly similar to phase1, was performed by National Research Institute of Tuberculosis and Lung Diseases (NRITLD) in two cities of Iran Rasht and Tehran. All stages of the study were performed in accordance with ISAAC protocol. The present study discusses data related to children of Tehran. A total of 3100 school children aged 13-14 years were questioned about asthma symptoms using written and video questionnaires of ISAAC study. For statistical analysis, initially a descriptive study of the available data was performed. Thereafter, chance corrected agreement between the two questionnaires was evaluated using Cohen’s Kappa co-efficiency.

Of the total of 3100 children, 52.4% were male and 47.6% female, with a mean age of 13.6 years. Although the questions discussed in the two questionnaires were not exactly similar, the results of the video questionnaires showed a statistically significant lower positive response to asthma symptoms as compared to the written version. Kappa co-efficiency ranged between 0.06- 0.21 (mean=0.12), which is considered poor for all variables.

Positive responses to having asthma symptoms were significantly higher using the written questionnaire compared to the video questionnaire. Similar to previous studies, agreement between the two was considered poor for all variables. Although factors such as language, culture, dwelling area, e.t.c. have special effects on results of these questionnaires, results indicate that the two questionnaires should be further studied and validated for this special group of patients in order to reach a better interpretation of prevalence of asthma symptoms.

The risk of asthma prevalence has increased dramatically in children in developed countries over the last three decade. The studies in developing countries have also detected an increased prevalence. There is limited data from ISAAC study in Iran. Considering ISAAC Study in Birjand in 1996, this study will reveals prevalence and time-trend of asthma in Birjand. Methods and Materials: For this purpose, a descriptive study was conducted. By simple sampling, 3540 subject aged 13-14 years, including all from 22 intermediate level schools were recruited for study using the International Study of Asthma and Allergies in Childhood (ISAAC) from across Birjand city in 2002. Subjects were studied by video questionnaires. In this method, the audiovisual presentation of the questionnaires included five scenes of asthma symptoms in different situation. After each scene, the subjects ticked the answer whether or not they experienced the same problems with breathing as the child in video. Analysis of data was done using descriptive analytic and chi-square test. There were 3,540 students including 49% females and 51% males from 22 intermediate schools. One girl school refused to participate in study. The amount of missing data was less than 1% each scenes. The prevalence rates in video questionnaire for any wheeze ever in life, and current wheeze in last 12 months, were 18%, 10.1% respectively. The prevalence of night cough in last 12 month, speech limiting wheeze at rest in last 12 month, and one or more time a month of any wheeze was 4.5%, 2.2% and 7.4% respectively. The prevalence of any wheeze ever in life, and current wheeze in last 12 month was higher in females compared with males (P<0.001). The results of this study on asthma symptoms, suggest an increase in the prevalence of asthma symptoms in Birjand when compared with prior study in this region. The results are suitable for comparison with other ISAAC studies. It also represents a baseline for further analytic epidemiological research.
