The foot forms an important support for the body, which  endure high ground reaction forces generated during activities of daily living. The structure and  movements of the foot are crucial for lower limb gait kinematics . The medial longitudinal arch (MLA) of the foot is the primary shock-absorbing structure particularly important for foot function . Increased body mass index (BMI) has been shown to affect the foot arch index. An arch index of less than 0.21 indicates cavus foot while greater than 0.26 is indicative of a planus foot whereas arch index between 0.21 and 0.26 corroborates normal arch height.

The aim of the present study is to correlate the arch index derived from foot print measurement in BMI based normal weight, overweight and obese young adults.

Methodology: The present study was conducted on 60 students of either sex in the age group of 18 to 25 years in the Department of Anatomy, School of medical sciences and research,Sharda University, Greater noida,UP. The standard anthropometric measures of height and weight were taken and BMI was calculated . Based on BMI, the students were divided into normal (19 to 24.9kg/m2), overweight (25 to 29.9kg/m2) and obese (>30kg/m2).Foot prints were taken on a graph paper and arch index was calculated.

Results: The mean arch index in normal, overweight and obese subjects was found to be 0.19±0.028, 0.2±30.043 and 0.26±0.045 respectively. Gender comparison did not reveal any significant difference(p>0.05) in all the three groups.

Conclusion: The results of the study may help in establishing preventive and rehabilitative interventions to improve the quality of life of overweight and obese individuals.
