Background : Our aim is to find out the correlation of serum levels of calcium, phosphorus and Alkaline phosphatase and Body Mass Index with occurrence of fractures in children. Methods : Study included total of 200 children between 2–14 years of age. Of these, 100 had sustained fractures and 100 were control samples. Study compared four parameters i.e serum calcium, phosphorus, alkaline phosphatase and body mass index to find out whether there is any correlation of these parameters with fractures. Results : Higher levels of Alkaline Phosphatase were found in children with fractures and lower levels of calcium and phosphorus were found in children with fractures than the control group. Body Mass Index of both the groups were similar. Conclusion : Significant correlation has been found between serum levels of calcium, phosphorus and alkaline phosphatase with fractures. But, no correlation between fractures and BMI has been found.
