Abstract
Purpose: This study was designed to evaluate the correlation between the degree of kyphosis among adolescent spine deformities and low back pain in male adolescent using the 3-Dimensional Whole Body Scanner as screening tool for kyphosis.

Materials and Methods: The 3-Dimensional Whole Body Scanner was applied to 220 first-year, secondyear and third-year high school male students in Seoul, in addition to administering a survey regarding the presence of back pain. From the gathered data, we calculated the A/B index to objectively analyze the degree of spinal deformity, more specifically, spinal kyphosis. We were able to obtain the A/B index of a total of 210 students except unmeasurable 10 students and analyzed the relationship between the degree of kyphosis and low back pain using logistic regression.

Results: 1. The average age, height, body weight and body mass index were 16.7¡¾0.9 years old, 173.1¡¾5.0 cm, 65.6 ¡¾10.2 kg, 21.8¡¾3.2 kg/m2. The average of A/B index is 11.3¡¾3.65 %. The maximum and minimum were 2% and 36%. A/B index data showed normal distribution
2. Low Back Pain did not correlate with age, height, or weight, but with the degree of thoracic spine kyphosis. As the degree of thoracic spine kyphosis increased by 1%, 5%, and 10%, the incidence of low back pain increased by 1.2 times, 2.5(¡Ö1.25) times and 6.2(¡Ö1.210) times respectively.

Conclusion: We concluded that the degree of kyphosis has a significant correlation to low back pain in male adolescences
