Abstract

We previously reported that infants with Asian-born parents are 3 times more likely to have IgE-mediated food allergy than those with Australian-born parents. It is unknown whether this translates to the increased risk of other allergic diseases later in childhood and whether ancestry interacts with other risk factors for allergic disease development. To compare prevalence and risk factors for allergic rhinitis, asthma, and aeroallergen sensitization at age 6 between children with East Asian-born and Caucasian-born parents. A total of 5276 1-year-old infants were recruited into a population-based longitudinal study of allergy. A total of 4455 children participated in age 6 follow-up (84.4%), including 3015 with Caucasian-born parents and 415 with East Asian-born parents. Children underwent skin prick tests to aeroallergens and questionnaires captured data on asthma, eczema, and allergic rhinitis. Compared with children with Caucasian-born parents, children of East Asian-born parents had more allergic rhinitis (19.9% [95% confidence interval (CI) 14.9-26] vs 9.3% [95% CI 8-10.8], P < .001) and aeroallergen sensitization (64.3% [95% CI 57.5-70.5] vs 34.4% [95% CI 32.2-36.7], P < .001) at age 6. Asthma was similar in both groups (...Continue Reading

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Allergies & Environmental Factors

Environmental factors are strongly associated with the prevalence of allergies and are an increasing health concern worldwide. Discover the latest research on Allergies and Environmental Factors here.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.

Babesiosis

Babesiosis is caused by parasites of the genus babesia, which are transmitted in nature by the bite of an infected tick. Discover the latest research on babesiosis here.
