Background and aim: Normal curvature of the spine might be changed as a result of its non-fixed feature. The aim of this study was to investigate the relationship between height, weight and body mass index (BMI) with curvature of the spine kyphosis and lordosis in 12-15 years old boys of Tehran.
Materials and Methods: This is a correlational study in which 97 accessible healthy boy students from Tehran region 2 with a mean age of 13/8 ± 0/8 years old were selected. After measuring height (157/4 ± 8/6 cm), weight (52/9 ± 11/9 kg) and calculating BMI (21/2 ± 3/9 kg/m2), the spinal mouse was used to assess spine alignment. To investigate the relationship between study variables Pearson correlation coefficient was used. Using SPSS software version 17, data were analyzed.
Results: According to the correlation coefficient results, in level of p<0/05 there was no statistically significant relationship between study variables including height and kyphosis curvature (r= -0/047), height and lordosis curvature (r= -0/026), weight and kyphosis curvature (r= 0/015), weight and lordosis curvature (r= 0/052), body mass index and kyphosis curvature (r= 0/059), and body mass index with lordosis curvature (r= 0/084).
Conclusion: Although it seems that anomalies of the spine have high prevalence among the students, the results of this study show that height, weight and body mass index could not be considered as an appropriate criteria to predict variation of angle of kyphosis and lordosis in the studied population.
