Purpose: To explore the effect of body mass index (BMI) on Craniovertebral Angle (CVA) and Shoulder Angle (SA) in Egyptian Adolescents.
Methods: Cross Sectional Study designe was used.Eighty-six physical therapy students were selected randomly, and their age were ranged from 18-27 years. They were divided into three groups according to BMI. The first group with normal BMI (18.5-24.9 Kg/m²), while the second group was overweight (BMI was ranged from 25-29.9 Kg/m²). The third group was obesity class I (BMI was ranged from 30-34.9 Kg/m²).Photogrammetry method used (the photographic sessions by mobile phone Samsung J-7 Camera and use of Corel Draw software to analyze the pictures).
Results: A significant difference was detected between normal BMI and overweight (p<0.02) and significant difference between normal BMI and obese (p<0.03). For SA there was significant difference between normal BMI and overweight (p<0.02). However, for CVA the relation between overweight and obese was not significant (p>0.2), and for SA non-significant difference between normal BMI and obese (p>0.41) and non-significant difference between overweight and obese (p>0.2).
Conclusion: overweight and obesity change CVA and forward head posture and overweight changed SA and so rounded shoulder appeared. However, obesity did not change SA and rounded shoulder.
