Individual home characteristics have been associated with indoor allergen exposure; however, the influence of neighborhood-level characteristics has not been well studied. We defined neighborhoods as community districts determined by the New York City Department of City Planning. ⋯ Neighborhood-level characteristics, specifically housing code violations, appear to be related to indoor allergens, which may have implications for future research explorations and policy decisions.

Randomized Controlled Trial
Effect of oral magnesium supplementation on measures of airway resistance and subjective assessment of asthma control and quality of life in men and women with mild to moderate asthma: a randomized placebo controlled trial.
Epidemiological data shows low dietary magnesium(Mg) may be related to incidence and progression of asthma. ⋯ Adults who received oral Mg supplements showed improvement in objective measures of bronchial reactivity to methacholine and PEFR and in subjective measures of asthma control and quality of life.

Background. Asthma is a common childhood illness. The objective of this study is to determine the incidence of physician-diagnosed asthma in preschool years and its relationship to host, prenatal and postnatal factors, early childhood factors, parental factors, household factors and demographic factors. ⋯ Conclusion. This study emphasizes the role of wheezing in infant and toddler age on early onset of asthma during preschool years. The results also provide additional importance of early exposures to environmental factors such as early infections, daycare attendance, and rural environment in the development of proper immune dynamics to prevent asthma.
