Brief Summary

This study aims to explore the relationship between posture and body composition in adolescents from Generation Z (born between 2002 and 2005). It was conducted as a cross-sectional study at a high school in Ankara, Turkey. A total of 572 students between the ages of 14 and 17 were included. Researchers used photographic analysis to measure head, neck, and shoulder posture, as well as a digital inclinometer to assess the curvature of the upper spine (thoracic kyphosis). Body composition-such as body fat percentage, fat-free mass, and body mass index (BMI)-was evaluated using a bioelectrical impedance analyzer. All participants and their parents provided informed consent. After data collection, participants attended an educational seminar about posture and healthy habits. The study was approved by the Gazi University Ethics Committee and conducted in accordance with the Declaration of Helsinki.
