The objectives of study were; (1) To locate and identify the post rally defected boys in the primary Schools of Greater Gwalior and analyze the extent and incidence of five common postural defects, namely, kyphosis, lordosis, scoliosis, knock knee and flat foot in different family back grounds. (2) To assess the influence of family type, caste, religion, dwelling condition, economics status, occupation and educational status of parents on various postural defects in primary School boys.  (3) To contribute to the body of knowledge from which the most common five postural defects can be know of Indian primary School boys of different family back grounds. (4) To offer suggestions to the parents of postural defected boys for their better prevention and management on the basis of the present study. (5) To determine the prevalence of five common postural defects among the Indian primary school boys so that the preventive and corrective measures can be suggested for formulating an effective physical Education programme for Indian primary school boys. It may be hypothesized that the occurrence of five common postural defects, namely, kyphosis, lordosis, scoliosis, knock-knee and flat foot in primary school boys is related to the family background of the individual.

1069 school boys of classes III, IV, V from Gwalior were selected as a sample by Stratified Random Sampling Technique.

The study was based on Descriptive and Diagnostic Research Design.

The findings of study were: (1) The number of boys suffering from single postural defect was higher in comparison to those suffering from multiple postural defects. (2) Among different types of postural defects identified, the prevalence for the flat foot was the highest followed by scoliosis, knock - knee and then kyphosis and the prevalence for lordosis was the lowest. (3) The prevalence of postural defects was higher in the nuclear families as compared to the joint families. (4) The occurrence of postural defects was highest among the scheduled castes followed by other backward classes and scheduled tribes. (5) Among different religions the postural defected boys in case of the Muslim were the highest followed by the Hindus, the Sikhs and then the Christian. (6) Number of boys suffering from postural defects was higher in the case of those residing in kutcha houses as compared to those residing in pakka house. (7) The number of postural defected boys was the highest among the parents who were employed as workers and was closely followed by the boys whose parents were involved in agriculture. The number of boys suffering from postural defects among business and private service families were found to be less as compared to the above two categories, whereas the postural defected boys were the least among the parents who were in the Government service. (8) The number of postural defected boys was the highest in the upper-lower economic class, followed by lower - lower, lower - middle, middle - middle, upper - middle and higher economic classes. (9) Health and education may have a positive influence on reducing the occurrence of postural defects. The number of postural defected boys was much less in the case of higher economic class where adequate attention was paid to the above two aspects. (10) The education of parents was related to the occurrence of postural defects among the boys. The number of postural defected boys was the maximum in case of illiterate parents, whereas, as the level of Education increased, the number of postural defected boys gradually reduced.
