Abstract

The present review aims to identify and summarize epidemiologic investigations published during 2011 on the environmental risk factors for asthma. Potentially eligible papers were identified by a MEDLINE search. In total, 1,130 items were retrieved. Based on a broad definition of environment, the following topics were included: obesity, diet, vitamin D, air pollution, farming environment, and social factors. Some of the more relevant contributions included evidence that 1) obesity precedes asthma, 2) fruit consumption is longitudinally associated with a lower risk of asthma and atopy, 3) a comprehensive statewide smoking ban was followed by a reduction in hospital admissions for asthma, 4) asthma is one of the diseases showing the largest burdens due to environmental tobacco smoke, 5) traffic-related urban air pollution is associated with bronchial inflammation as measured by fractional exhaled nitric oxide and uncontrolled asthma, 6) aeroallergens and desert dust may contribute to the short-term effects of air pollution and asthma, and 7) maternal exposure to air pollution before and during pregnancy may alter the immune competence in offspring.

This was a large population-based study (189,783 children born in Stockholm) showing a dose–response relationship between the degree of maternal overweight status during pregnancy and increased risk of asthma in the child. The latter, if causal, may explain about 10 % of asthma in the study population.

This was a large study measuring the aeroallergen levels and their interaction with traffic air pollution, in relation to asthma hospitalizations, in a large urban population (~12 million). The study found an independent association between aeroallergens and hospitalizations for asthma independent of PM 2.5 and PM 10 . For some aeroallergens, their associations were stronger on days with higher levels of air pollution.

Some studies have reported raw milk consumption as a potentially protective factor against asthma and allergy. This study is the first to assess which components of raw milk are associated with its protective role. The finding that increased levels of the whey proteins were inversely associated with asthma paves the way for more focused mechanistic and intervention studies.

There is growing evidence that interactions between the gut microbiome and the immunologic system in early life have programming effects on a number of physiologic mechanisms and diseases. Genomic techniques have been used to type microbial DNSA in farm dust to show that children living on farms are exposed to a wider range of microbes—something that partially explains the inverse relation between asthma and growing up on a farm.

The study is innovative in its use of structural equation models to identify direct and indirect pathways. The study suggests that in low-income populations, early-life interventions may be useful to reduce asthma disparities and to break their propagation from one generation to another.
