Prevalence Of Rhinitis In Children Research Articles

Association of rhinitis with asthma prevalence and severity

Asthma and rhinitis often co-exist in the same patient. Although some authors observed a higher prevalence and/or greater severity of asthma in patients with rhinitis, this view is not homogeneous and the debate continues. The aim of our study is to describe the prevalence of rhinitis in children and adolescents and to analyse their relationship with the prevalence of asthma. A multicentre study was conducted using the methodology of the International Study of Asthma and Allergies in Childhood (ISAAC). The target population of the study was all those school children aged 6–7 and 13–14 years from 6 of the main health catchment areas of Galicia (1.9 million inhabitants). The schools required were randomly selected, and all children in the targeted age ranges were included. Multiple logistic regression was used to obtain adjusted prevalence odds ratios (OR) between asthma symptoms of the schoolchildren and rhinitis prevalence. The results were adjusted for parental smoking habits, maternal education level, cat and dog exposure, and obesity. A total of 21,420 valid questionnaires were finally obtained. Rhinitis was associated with a significant increase in the prevalence of asthma in both age groups. The highest OR were 11.375 for exercise induced asthma (EIA) for children with recent rhinoconjunctivitis and 9.807 for children with recent rhinitis in 6–7 years old group. The prevalence OR’s are higher in EIA and severe asthmatics. Rhinitis in children and adolescents is associated with a higher prevalence and severity of asthma.

Allergic rhinitis in children: MASTering a common problem

Allergic rhinitis is a common condition amongst children which can impact upon their quality of life and school performance. Mark Greener analyses the causes, symptoms and co-morbidities, and suggests how the condition can be successfully managed Estimates of the prevalence of allergic rhinitis in children vary widely between countries. However, up to 40% of children in the UK may have allergic rhinitis, which seems to be linked to numerous factors and can impair educational performance and quality of life, exacerbate co-morbid asthma, and increase the risk of internalising behaviours. The assessment of patients with allergic rhinitis should cover four areas, encompassed by the mnemonic ‘MAST’: medication, associated conditions, severity, and timing.

Several effective treatments—including antihistamines and intranasal corticosteroids—are available, but teaching staff may need education about this ubiquitous condition.

Prevalence and comorbidity of allergic diseases in preschool children

PurposeAllergic disease and its comorbidities significantly influence the quality of life. Although the comorbidities of allergic diseases are well described in adult populations, little is known about them in preschool children. In the present study, we aimed to assess the prevalence and comorbidity of allergic diseases in Korean preschool children.MethodsWe conducted a cross-sectional study comprising 615 Korean children (age, 3 to 6 years). Symptoms of allergic diseases were assessed using the Korean version of the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire that was modified for preschool children. Comorbidities of allergic diseases were assessed by 'In the last 12 months, has your child had symptoms?'.ResultsThe prevalence of symptoms of asthma, allergic rhinitis, and atopic dermatitis as recorded using the ISAAC questionnaire, within the last 12 months was 13.8%, 40.7%, and 20.8%, respectively. The symptom rates of allergic conjunctivitis, food allergy, and drug allergy were 14.8%, 10.4%, and 0.8%, respectively. The prevalence of allergic rhinitis in children with asthma was 64.3% and that of asthma in children with allergic rhinitis was 21.6%. The prevalence of rhinitis in children with conjunctivitis was 64.8% and that of conjunctivitis in children with rhinitis was 23.6%.ConclusionThe prevalence of current rhinitis in our preschool children is shown to be higher than that previously reported. Allergic conjunctivitis is closely associated with asthma and allergic rhinitis. However, further studies are warranted to determine the prevalence and effects of these comorbidities on health outcomes in preschool children.

Effect of Rural Environment on the Prevalence of Rhinitis in Children From Mexicali BC, Mexico

ISEE-824 Introduction: Asthma and allergic diseases in children have increased in many countries in the last decades and multiple theories try to interpret these changes. Some studies mention that lifestyle and living early ages in a rural environment can reduce the risk of atopy. Objective: We conducted a cross-sectional study to determine the prevalence of asthma and allergic rhinitis and identify the role of the rural environment in the development of these illnesses in a random sample of schoolchildren (n = 2087) aged 6 to 7 years residing in Mexicali, Baja California, Mexico. Materials and Methods: The methodology proposed by the International Study of Asthma and Allergies in Childhood (ISAAC) phase 1 was applied. Information was obtained through a standardized questionnaire completed by the children's parents. The information was analyzed using logistic regression models adjusted for potential confounders. Results: The prevalence of wheezing in the last 12 months and allergic rhinitis (defined by the presence of nasal symptoms and nasal and ocular symptoms) were 10.5% [95% confidence interval (CI) 9.1%–11.9%], 25.0% (95% CI 23.0%–27.0%), and 10.5% (95% CI 9.1%–11.8%), respectively. The children that report living in the rural environment in the first years of life presented a low risk for allergic rhinitis OR (odds ratio) = 0.43 (95% CI 0.24–0.77) for nasal symptoms and OR = 0.39 (95% CI 0.16–0.93) for nasal and ocular symptoms, adjusted by family history of asthma, type of school, animal in home, humidity in home, passive smoking, and pesticides exposure. Conclusions: Our results support the role of the rural environment as protector for rhinitis. We observed that the contact with certain factors related to the rural environment, especially in the first years of life, can modify the development of these illnesses independently of the family history of asthma.
