Background: Infant antibiotic use is associated with increased risk of asthma. We examined the population impact of antibiotic exposure in the first year of life on the burden of pediatric asthma in British Columbia, Canada, using simulation modeling.
Methods: We performed a Bayesian meta-analysis of empirical studies to construct dose-response equations between antibiotic exposure in the first year of life and pediatric (<19 years of age) asthma.

Background: Polycyclic aromatic hydrocarbons (PAHs) are environmental contaminants that can cause a variety of health problems. This study sought to determine whether there was a relationship between PAHs and current asthma in adults.
Methods: This cross-sectional study utilized data from the National Health and Nutrition Examination Survey (NHANES) from 2007 to 2016 and employed multifactor logistic regression, subgroup analyses, and smoothed curve fitting to examine the linear and nonlinear associations between PAHs and current asthma.

The association between early childhood serum 25-hydroxyvitamin D (25(OH)D) and eosinophilic asthma remains unclear. We investigated this association using multicentre prospective data from 584 children with a history of bronchiolitis requiring hospitalisation (high-risk population). Low serum 25(OH)D levels (<20 ng/mL) were associated with increased odds of developing eosinophilic asthma (adjusted OR 2.

Introduction: Overweight and obesity are chronic and multifactorial diseases with a strong genetic component contributing to weight gain across all age groups. This study aimed to conduct a Genome-wide Association Study (GWAS) on a cohort of 1,004 Brazilian children (5-11 years old) to identify specific DNA regions associated with susceptibility to overweight.
Methods: The GWAS was performed on children participating in the SCAALA (Asthma and Allergy Social Changes in Latin America) program, with participants classified as either overweight or non-overweight.
