The aim of the study was to assess the prevalence of lower limb postural deformities among male school students of upper and lower socio-economic classes in the Union Territory of Chandigarh. By using a convenient sampling technique, 949 male school students were selected from six government and three non-government schools of the Union Territory of Chandigarh. The student’s age ranged between 13 and 17 years and was categorised into two categories, i.e., upper and lower socio-economic classes, with the help of the Socio-economic Status Scale (SESS). The selected variables such as age, height, weight, BMI, flat foot (medial longitudinal arch), knock knee (intermalleolar distance) and bowlegs (intercondylar distance) were measured with standardised tests and tools. Descriptive statistics and student’s t-test were employed to analyse the data. The study revealed that 24.76%, 20.13 %, and 7.69% of male school students in Chandigarh suffered from flat foot, knock knee and bowleg deformities, respectively. Flatfoot and knock knee deformities were more prevalent among the male school students of upper socio-economic class. In contrast, bowlegs were common in male school students of lower socio-economic class. The male school students of upper socio-economic class had superior height, body weight and body mass index as compared to lower socio-economic class.
