Abstract

Phthalate exposure is related to the development of allergic diseases; however, studies regarding its effect on lung function are limited. Our study aims to identify an association between phthalate exposure at different ages and lung function in children at age 9 by conducting a cohort study. The Taiwan Birth Panel Study (TBPS) was established from April 2004 to January 2005. Urine samples were collected from children in the TBPS cohort at ages 2, 5, and 9years. Urinary phthalate metabolite concentrations were measured via ultrahigh-performance liquid chromatography coupled with tandem mass spectrometry. Questionnaires, lung function tests and serum IgE levels were obtained from children at the age of 9. Multiple linear regressions adjusted for confounding factors were applied to investigate the associations between phthalate exposure at different ages and lung function at age 9. Our results demonstrate that in children with allergic diseases, a per log unit increase in the urinary phthalate metabolite mono-ethyl phthalate (MEP) concentration at age 9 was associated with a decreasing forced expiratory volume in 1 sec (FEV1) (β=-25.22; 95% CI: -47.53 to -2.91 per log ml/ln-μg/g cr) and forced vital capacity (FVC) (β=-32.3; 95% ...Continue Reading

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.
