OBJECTIVE
Asthma in children and adolescents is a heterogeneous syndrome comprised of multiple subgroups with variable disease expression and response to environmental exposures. The goal of this study was to define homogeneous phenotypic clusters within a cohort of children and adolescents with
OBJECTIVE
Given widespread interventions to reduce environmental tobacco smoke (ETS) exposure and improve asthma control, we sought to assess the current impact of ETS exposure on children with asthma.
METHODS
We analyzed 2003-2010 data for nonsmoking children aged 6 to 19 years with asthma from the
OBJECTIVE
Studies have identified associations between household secondhand tobacco smoke (SHS) exposure and induction of childhood asthma. However, the true nature and strength of this association remains confounded in many studies, producing inconsistent evidence. To look for sources of potential
OBJECTIVE
To evaluate the effect of tobacco smoking, respiratory symptoms, and asthma on lung function among Mexican adults who were evaluated during a medical exam in a private health clinic.
METHODS
Reference prediction equations were generated for spirometry parameters [forced vital capacity
Smoking is the leading cause of preventable death worldwide. Hundreds of millions of individuals still smoke, affecting their health as well as that of their peers, family and offspring. Smoking is a well-established prime risk factor for chronic obstructive pulmonary disease and hampers the
OBJECTIVE
Associations between single-nucleotide polymorphisms in the beta2-adrenergic receptor gene and asthma and wheeze have been inconsistent. Recent studies indicated that tobacco smoke affects beta2-adrenergic receptor gene expression and associations of beta2-adrenergic receptor gene variants
BACKGROUND
Genome-wide association studies have identified novel genetic associations for asthma, but without taking into account the role of active tobacco smoking. This study aimed to identify novel genes that interact with ever active tobacco smoking in adult onset asthma.
METHODS
We performed a
OBJECTIVE
To examine the prevalence of asthma and the relation between tobacco use and asthma among university students in Costa Rica.
METHODS
Cross-sectional study of 1279 adolescents and young adults enrolled in careers in the health sciences in public and private universities in Costa
BACKGROUND
The negative influence of tobacco smoke on the course of bronchial asthma is complex and includes direct toxic effects on the epithelium of the respiratory tract. It is estimated that in developed countries, approximately 25 percent of adult asthmatics are tobacco smokers. Knowledge of
OBJECTIVE
The goals were (1) to develop an index measure of environmental tobacco smoke based on parent self-report of smoking behaviors and (2) to determine whether the index score was associated with children's present and future cotinine levels.
METHODS
Data were drawn from a community
BACKGROUND
Exposure to environmental tobacco smoke (ETS) is a risk factor for childhood asthma. Its association with asthma in adults is less clear.
METHODS
In a multicentric population study on asthma prevalence in adults, specific enquiries were made into childhood and adulthood exposure to
OBJECTIVE
To analyse the association between tobacco smoking, exposure to second-hand smoke (SHS) and reports of wheezing and asthma in a sample of schoolchildren.
METHODS
A structured questionnaire was administered to 1766 students (7th grade, aged 12-13 years) at 25 schools in Terrassa, Spain
OBJECTIVE
We sought to determine the effects of exposure to environmental tobacco smoke (ETS) and childhood cigarette smoking on asthma symptoms among middle school children in North Carolina.
METHODS
During 1999-2000, information was collected from a survey completed by the children. Outcomes of
BACKGROUND
Tobacco smoke exposure increases breathing problems of children. Texas Children's Health Plan is a Managed Medicaid and Children's Health Insurance Program (CHIP) managed care provider. The aim of this study is to determine associations among tobacco smoke exposure, asthma prevalence, and
The effect of common indoor combustion heating sources on childhood asthma is not well described. The objective was to determine if the use of woodstoves in the home or other factors such as environmental tobacco smoke exposure were associated with the frequency of asthma-related symptoms among
