Objectives The purpose of this study is to investigate correlation between body mass index (BMI) and the Sensitiv $Imago^{TM}$ in pediatric patient. Methods The study was conducted with 79 children, who were 5 to 18 years old. They were tested using Sensitiv $Imago^{TM}$. Their height, weight were measured for body mass index to find out the relationship between Body Mass Index (BMI) and the result of Sensitiv $Imago^{TM}$ (SI). Results 1. The percentages of the normal weight group (74.68%), overweight group (6.33%), and underweight group (18.99%) were shown respectively. 2. No one was belong to Acute Processes in either groups. 3. In normal weight group, there were Active Processes (16.9%), Unstable Remission (69.5%), Inactive Processes (13.6%), Inactive Process or Development Risk (0.0%). In overweight group, there were Active Processes (20.0%), Unstable Remission (40.0%), Inactive Processes (40.0%), Inactive Process or Development Risk (0.0%). In underweight group, there were Active Processes (6.7%), Unstable Remission (66.7%), Inactive Processes (20.0%), Inactive Process or Development Risk (6.7%). Conclusions There were no significant relationship between Body Mass Index (BMI) and Sensitiv $Imago^{TM}$ in pediatric patient. Considering that the number of subjects involved in this study was not enough to confirm any results, further studies are necessary to confirm this relationship.
