Behavioral Circuit Breathing Training for Smoking Cessation in Youth Who Use E-cigarettes

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized, three-arm study compares a behavioral circuit breathing training to diaphragmatic breathing and to usual daily activities in e-cigarette users aged 15-25. Thirty participants will be assigned equally to each group and will follow their respective training three days a week for six weeks. Outcomes related to smoking cessation and respiratory function will be assessed before and after the intervention. The study is conducted at the Faculty of Sports Science, Chulalongkorn University in Bangkok, with recruitment limited to individuals without major heart or lung diseases and who meet other eligibility criteria. The goal is to determine whether the circuit approach offers additional benefit over diaphragmatic breathing or standard activities.
