Method: A total of four hundred (N=400) male school students of Chandigarh, consisting of two hundred (n=200) from private schools and two hundred (n=200) from government schools. The male students were selected by using a convenient sampling technique. The subject’s age ranged between 13 to 17 years. Flex curve and sociometer were used to measure the spinal deformities (thoracic kyphosis, lumber lordosis and scoliosis). Descriptive statistics and t-test were employed to analyze the data. The level of significance was set at 0.05.

Result: The result of the study showed that overall, 44.25% of school students in Chandigarh suffered from spinal deformities. Thoracic kyphosis was high in students of private schools whereas lumber lordosis was more prevalent in government schools. Scoliosis was reported in equal numbers of students in private and government schools. A significant difference was found in the degree of flexion in the thoracic region (kyphosis) of the spine between government and private school students.

Conclusion: The incidence of thoracic kyphosis might be related to the school type as in the present study thoracic kyphosis was reported to be high among the students of private schools.
