Asthma is a chronic respiratory disease and a major public health problem globally. This study aimed to determine the prevalence of asthma and related symptoms in schoolchildren in Dezful city, southwest Iran.

In this cross-sectional descriptive analytical study, the prevalence of asthma symptoms was measured using a randomized cluster sampling method among 2,978 schoolchildren aged 6-14 years. A validated questionnaire from the International Study of Asthma and Allergies in Childhood (ISAAC) was used from January to February 2020. The chi-square test was used to determine the relationship between variables, which were expressed as percentages, with a p‐value <0.05 considered statistically significant.

The overall prevalence of asthma was 4.7% (CI=3.98 - 5.54), significantly higher among 13-14-year-olds compared to the 6-7-year-old age group (6.4% vs. 3.1%, p<0.001) and in males versus females (6.9% vs. 2.5%, p<0.001). The total prevalence of wheezing in the last year, the main symptom of asthma, was 7.2% (CI=6.31 - 8.20), significantly higher among 13-14-year-olds (8.4% vs. 6.1%, p<0.009) and male schoolchildren (9.6% vs. 4.7%, p<0.001).

According to our findings, and compared to the previous ISAAC study in Iran, the prevalence of asthma symptoms was relatively low among Dezful schoolchildren. Further epidemiological studies are needed to investigate factors affecting this disease, such as indoor and outdoor environments, as well as their effects on gene expression over time.

Nutrition security is a vital component of growth and development in a nation. However, dietary diversity and availability of healthy food are serious challenges to many local communities in Ethiopia. The objective of the study was to identify the status and the determinants of nutrition security of school-age children in Northwest Ethiopia.

Primary data were collected and analyzed using a binary logistic regression model to determine the significance of nutrition security odds ratio of 12 variables.

The results revealed that around 55.4% of school-age children were nutritionally insecure and underweight, and 44.6% were stunted. The significant determinants of nutrition security in the study area were milk consumption, healthy eating habit, fruits and vegetables consumption, educational status of the guardian, meat consumption, and the child’s place of residence.

The findings of the study showed the need for nutrition education of the children and their guardians, and the need for accessibility of diverse and nutritious food products to help the school-age children with acute wasting and stunting problems they are facing.

Childhood obesity could induce some risk factors for cardiovascular disease (CVD) including serum lipid abnormalities, hypertension, and atherosclerosis. The present study aimed to comparison the lipid profile in normal children with cases having overweight, obesity and central obesity. In this case control study, which was conducted 2013, serum lipids for three groups of children including cases with overweight (Body mass index (BMI): 85-95th percentiles to age and sex and waist circumference (WC) <90th percentile to age and sex = Case group1), central obesity without general obesity (BMI <85th percentiles and WC ≥ percentile 90 = Case group 2) and central obesity with general obesity (BMI ≥95th percentile and WC ≥ percentile 90 = Case group 3) were compared with control group (BMI < 85th percentiles WC <90th percentile). Data were analyzed using software SPSS-16 by chi-square and ANOVA tests at significance level α=0.05. Each group consisted of 100 individuals. The highest mean of serum lipids and the highest extent of dyslipidemia existed in the children having central obesity along with general obesity. So that 49%, 28%, and 38% students of this group show hypertriglyceridemia, hypercholesterolemia, and low high-density lipoprotein cholesterol (HDL-C). Odd ratio of hypertriglyceridemia, hypercholesterolemia and low HDL-c, in children with at least one abnormal index (BMI and /or WC) compared with control group were 3.73 (95% CI: 1.98, 6.99), 1.37 (95% CI: 1.71, 2.65) and 2.98 (95% CI: 1.51, 5.87), respectively. With regard to the relationship between central obesity and adverse changes in lipid profiles, the screening children for central obesity to prevention of cardiovascular disease are recommended.

Methods learnt by children to cope with stress will be used in their adolescence. Failure to learn adaptive coping strategies causes some mental, physical and behavioral problems which continue until adulthood. The current study was conducted to investigate the methods of coping with stress among Iranian school-age children. Patients and A descriptive study was conducted in which a randomly selected sample of 839 students of third to fifth grade of primary school in Tabriz, Iran participated. The data were collected using the Schoolagers` Coping Strategies Inventory questionnaire. SPSS software was employed to analyze the data by percentage, absolute frequency, and linear regression test. All coping methods inserted in the questionnaire were used by students. More than 70% of students mentioned “pray”, “say I’m sorry or tell the truth”, and “try to relax, stay calm” out of 26 cases of coping strategies. According to more than 60% of children, “pray”, “say I’m sorry or tell the truth”, and “draw, write, or read something” were the most useful coping methods and “pick on someone” and “yell or scream” were not mostly used by the children under study. Children use variable methods to cope with their stress. Therefore, parents, health trainers and school authorities should distinguish non-adaptive methods of children and teach them the adaptive coping strategies.
