Does Obesity Increase Respiratory Tract Infections in Patients with Asthma?

ABSTRACT:

Background

Because respiratory tract infections (RTIs) precede most exacerbations, a better understanding of the risk factors of RTIs and RTI-associated exacerbations in patients with asthma is a pressing public health need. Obesity in patients with asthma is associated with worse asthma control and higher asthma-associated health care utilization, but its effect on RTI risk is unknown.

Objective

We aimed to study the association of body mass index (BMI) classification on the risk of self-reported RTIs and related asthma morbidity among adults and children with asthma.

Methods

This post hoc analysis of 5 large asthma trials involving 747 children and 1287 adults compared BMI classification, defined as lean, overweight, and obese based on age-appropriate BMI and BMI-pe
