Prevalence and Association of Dysfunctional Breathing With Nicotine Dependence and Physical Activity Among Young Smokers
An observational study of Dysfunctional Breathing and Physical Activity, run by Istinye University.
Trial summary
We will structure the study's summary to provide a clear and accessible overview for patients, families, and healthcare providers. The research will examine young adult cigarette smokers aged 18 to 24 to estimate the prevalence of a dysfunctional breathing-compatible symptom pattern using the Nijmegen Questionnaire.

About this study
Official title: Prevalence of Dysfunctional Breathing and Its Association With Nicotine Dependence and Physical Activity Level Among Young Smokers: A Cross-Sectional Study
We will structure the study's summary to provide a clear and accessible overview for patients, families, and healthcare providers. The research will examine young adult cigarette smokers aged 18 to 24 to estimate the prevalence of a dysfunctional breathing-compatible symptom pattern using the Nijmegen Questionnaire. Furthermore, the study will assess how nicotine dependence severity-measured via the Fagerström Test for Nicotine Dependence-and physical activity levels-assessed using the International Physical Activity Questionnaire-relate to this symptom burden. We will recruit participants through social media announcements and conduct face-to-face evaluations at Istinye University. The project will employ hierarchical linear and binary logistic regression models, adjusting for age, sex, and body mass index, to determine independent predictors of dysfunctional breathing. Ultimately, the findings will provide valuable insights into the combined impacts of smoking severity and physical activity on respiratory health in young adults.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Observational evaluation.Other
This study will not involve any experimental medical treatment or intervention. It will be an observational evaluation where participants will complete self-report instruments, including the Fagerström Test for Nicotine Dependence, the International Physical Activity Questionnaire, and the Nijmegen Questionnaire, along with a sociodemographic form during a single face-to-face session.

What is being measured
The primary outcome is the main question the study is designed to answer.
Fagerström Test for Nicotine Dependence
his instrument will assess the severity of nicotine dependence through six items evaluating daily cigarette consumption and smoking patterns.
Measured: Measured once during the single face-to-face evaluation session
Nijmegen Questionnaire
This questionnaire will assess the symptom burden of respiratory, neurovegetative, and neuromuscular features to identify a dysfunctional breathing-compatible symptom pattern.
Measured: Measured once during the single face-to-face evaluation session.
International Physical Activity Questionnaire Short Form
This tool will evaluate the participant's physical activity levels over the previous week by recording the duration and frequency of walking and physical activities.
Measured: Measured once during the single face-to-face evaluation session.
