Association between e-cigarette exposure and ventilation homogeneity in young adults: a cross-sectional study.

ABSTRACT:

Background

The number of young people who use e-cigarettes is rising. It remains unclear whether e-cigarette use impairs lung function. We aimed to compare ventilation distribution between young adults exposed to e-cigarettes and an unexposed group.

Methods

Study participants included otherwise healthy young adults (18-24 years) who self-reported e-cigarette use and unexposed participants who had no history of e-cigarette, tobacco or cannabis exposure. Exposure to e-cigarettes was defined using three measures: 1) ever-exposed, 2) daily use and 3) puff frequency, which includes none (unexposed), minimal (<2 puffs·h^-1), moderate (3-4 puffs·h^-1) and heavy (≥5 puffs·h^-1). Ventilation distribution was measured using the multiple-breath washout tes
