BACKGROUND The influence of asthma candidate genes on the development from wheeze to asthma in young children still needs to be defined. OBJECTIVE To link genetic variants in asthma candidate genes to progression of wheeze to persistent wheeze into childhood asthma. MATERIALS AND METHODS In a prospective study, children with recurrent wheeze from the ADEM (Asthma DEtection and Monitoring) s...
Seasonality of asthma may result from varying exposures. This cross-sectional study was designed to examine the relationship between indoor environmental factors and seasonal childhood asthma. Study subjects were participants from the International Study of Asthma and Allergies in Childhood (ISAAC) in 2004, a population-based surveillance, which included school children aged 6-15 yr in south Ta...
OBJECTIVE We calculated the population attributable fraction (PAF) of Canadian childhood asthma due to modifiable environmental exposures, in order to estimate their relative contributions to asthma development based on the current literature. METHODS We conducted a systematic review to determine Canadian childhood asthma incidence, Canadian prevalence of exposure to airborne pollutants and i...
Childhood asthma is a major concern because it leads to more hospital visits and a heavy economic burden. Proper management and prevention strategies for childhood asthma must be based on correct evaluation of prevalence and risk factors for its development. In Korea, nationwide studies were conducted in 1995 and 2000 on students from 68 elementary schools (age, 6-12 years) and junior high scho...
background: allergic diseases including asthma, allergic rhinitis (ar) and eczema are common chronic diseases in children. the purpose of this study was to determine the prevalence of asthma, ar and eczema in sari, iran. methods: this study was carried out on all elementary schools selected as a cluster from february 2010 to july 2010 in sari, north of iran. a questionnaire was provided accordi...
The aetiology of childhood asthma is complex. An early dysfunction in the immunological development of the innate immune system in combination with environmental factors possibly triggers asthma. CD14 and toll-like receptors are important components of the innate immune system. The aim of this systematic review was to obtain a better insight into the relation between CD14 and toll-like receptor...
There is a growing body of evidence attesting to links between early life exposure to stress and childhood asthma. However, available evidence is largely based on small, genetically high risk samples. The aim of this study was to explore the associations between the course of maternal depressive symptoms across early childhood and childhood asthma in a nationally representative longitudinal coh...
OBJECTIVES Recent studies have explored the potential for swimming pool disinfection by-products (DBPs), which are respiratory irritants, to cause asthma in young children. Here we describe the state of the science on methods for understanding children's exposure to DBPs and biologics at swimming pools and associations with new-onset childhood asthma and recommend a research agenda to improve o...
Problem statement: As a chronic condition, asthma may increase the risk of mood disorders. Understanding the association between asthma and mood disorders has important implications for asthma treatment and follow-up in primary care settings. Approach: To investigate whether asthma exposure during childhood is associated with the risk of mood disorders during adolescence and young adulthood, a ...
background asthma is one of the most important childhood diseases in developing countries. the prevalence, mortality, and economic burden of the disease have taken a rising trend since 1960, and this increase was more marked in children. the presents study aimed to assess the prevalence of asthma symptoms diagnosed by international study of asthma and allergies in childhood (isaac) questionnair...
