Background: Asthma as a chronic disease may affect the growth process. The aim of this study was to investigate the anthropometric indices in 2-18 years old children with asthma and compare them with the control group. Patients and Methods: In a case-control study, 150 asthmatic children with age of 2-18 years as case group and 300 age- and sex-matched healthy children as control group were randomly included. The height, weight, and body mass index (BMI) of both group measured by the standard method and Z score was calculated. Data were analyzed using SPSS, chi-square and analysis of variance. Results: Totally, 290 boys (64.4%) and 160 girls (35.6%) with mean age of 6.58±2.82 years were evaluated. Case group had significantly lower height compared to the healthy control group (117.00±0.17 cm vs. 121.00±0.15 cm respectively, P=0.025). No significant differences were detected in weight (23.13±9.75 kg vs. 24.62±10.36 kg, P=0.145) and BMI (16.32±3.10 kg/m2 vs. 16.28±3.16 kg/m2, P=0.900) between case and control groups, respectively. There were no significant relationships between normal and abnormal Z scores of height, weight and BMI in case and control group (P>0.05). Conclusion: Despite 4 cm difference between the age of two groups, no differences in height, weight ad BMI between two groups may be due to good control of the disease in the case group or lack of significant growth related effect of asthma.
Context: Atopic dermatitis is among the most common chronic diseases in children, with increasing prevalence. Objectives: This study evaluated the relationship between the microbial composition of nasal nares and atopic dermatitis severity. Study Selection: This meta-analysis included all types of studies (experimental and observational) on nasal colonization of pediatrics (age ≤ 19 years old) with a diagnosis of AD confirmed by a physician. The following search strategy was used in the databases: Atopic dermatitis AND (nasal OR nares). Results: Twenty-two studies were included in our analysis. Nine studies compared the odds of S. aureus nasal colonization between AD pediatrics and non-AD healthy controls. In 13 studies, there was no control group. Subgroup analysis was performed on eight studies regarding AD severity in pediatrics with positive nasal colonization of S. aureus. Pooled analysis showed that S. aureus was colonized in 38% of the pediatrics with mild AD, 50% with moderate AD, and 22% with severe AD. The random-effects model showed that the odds of nasal colonization of S. aureus were significantly higher in AD pediatrics than in non-AD healthy controls (OR: 2.52; 95% CI (1.60, 3.97); I2 = 72%). Conclusions: The nasal cavity of pediatric AD patients was more colonized with Staphylococcus aureus than in healthy children. More studies on children with severe AD are needed to accurately prove the role of S. aureus colonization in the severity of atopic dermatitis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
