Prior research suggests that immigrant enclaves provide respiratory health benefits for US Hispanic residents. We test if immigrant enclaves provide differential respiratory health benefits for Hispanic children in El Paso (Texas) based on individual-level factors. Results reveal that higher neighborhood immigrant density is associated with reduced odds of wheezing, but that the protective immi...

BACKGROUND We recently reported links between frequent paracetamol (acetaminophen) use and wheezing and asthma in adults and children, but data are lacking on possible effects of prenatal exposure on wheezing in early childhood. METHODS In the population based Avon Longitudinal Study of Parents and Children (ALSPAC) women were asked twice during pregnancy (at 18-20 weeks and 32 weeks) about t...

This study aimed to measure the prevalence rates for asthma and rhinitis and the association between the two conditions. This was a cross-sectional study of 3,015 adolescents (13-14 years of age) in Fortaleza, Ceará State, Brazil, in public and private schools, using the protocol from the International Study of Asthma and Allergies in Childhood (ISAAC), in 2006-2007. Prevalence rates were 22.6%...

Twenty four hour profiles of serum theophylline concentrations were examined in 15 asthmatic children taking a new theophylline preparation once a day. Peak concentrations occurred at a time when nocturnal wheezing is likely. Fluctuation in concentrations throughout the day was greater than with other currently available preparations, but the importance of this has yet to be determined.

BACKGROUND Prevalence surveys of asthma and/or wheezing among all children aged between 7 1/2 and 8 1/2 attending state and private schools in the London Borough of Croydon were conducted in February 1978 and February 1991. Two population based case-control studies drawn from the survey responders were used to investigate the association between childhood wheeze and characteristics of the home ...

Received: 03/03/03; accepted: 09/12/03 ABSTRACT To measure asthma prevalence and severity among children in Baghdad, we randomly sampled 3360 primary-school children and had their parents complete standardized questionnaires. The respo...

BACKGROUND Asthma is a major cause of disability, health resource utilization and poor quality of life world-wide. We set out to generate estimates of the global burden of asthma in adults, which may inform the development of strategies to address this common disease. METHODS The World Health Survey (WHS) was developed and implemented by the World Health Organization in 2002-2003. A total of ...

A hypothesis has been suggested stating that children exposed early to infections are less likely to develop atopy or asthma. The authors investigated the relation between risk of childhood asthma and number of siblings as well as day-care attendance, as factors possibly increasing the likelihood of early infections, and breastfeeding as a factor reducing them. A case-control study was carried ...

The aim of this prospective study of a population of children (age, 2-15 years) hospitalized for severe asthma was to test them for acute infection due to Mycoplasma pneumoniae and acute infection due to Chlamydia pneumoniae. Of 119 patients with previously diagnosed asthma, acute M. pneumoniae infection was found in 24 (20%) and C. pneumoniae infection was found in 4 (3.4%) of the patients dur...

A double-blind controlled study of 14 preschool children with recurrent wheezing episodes was performed to show the effectiveness of nebulised sodium cromoglycate in inhibiting exercise-induced bronchoconstriction in this age group. All 14 children showed markedly less exercise-induced bronchoconstruction after nebulised sodium cromoglycate, 13 of them to a degree indistinguishable from results...
