Is this trial a fit for you?
✓Likely a good fit
Healthy university students aged 18–35 who regularly use smartphones and can stand and perform daily activities independently.
✕Probably not a fit
Individuals with pre-existing cardiovascular, pulmonary, neurological, or orthopedic conditions affecting posture or breathing may not benefit from the findings.

What this trial studies
This cross-sectional study will assess healthy university students aged 18–35 to see if smartphone addiction relates to postural changes and breathing control. Participants will complete surveys on smartphone use and breathing function, and posture will be measured with the New York Posture Rating Chart. Data will be analyzed with logistic and linear regression to identify independent associations while adjusting for factors like age, sex, BMI, smoking, and usage duration. The goal is to understand potential musculoskeletal and respiratory implications of excessive smartphone use in young adults. The study will be conducted April to September 2026 at Istanbul Medeniyet University in Istanbul, with informed consent obtained from all participants.
Why it matters
Potential benefit: If associations are found, this could inform strategies to reduce posture-related and breathing issues in heavy smartphone users.
How similar studies have gone: Other observational studies have reported links between screen time, posture, and breathing, but this specific combination in young adults is less established.
