INTRODUCTION: Our main goal was to present normal BMD measurements in pubertal males and females in order to make contribution to the the database of normative BMD values in our country.
METHODS: In this study 30 pubertal subjects (14 males, 16 females) with Tanner stage II-V having normal BMD values were enrolled. The mean ages of the male and female groups were 13.6±1.4 and 13.7±1.6 years, respectively (P>0.05). The BMD measurements of lumbar spine (L1-4) and femoral neck were done by dual x-ray absorptiometry (DXA). Lumbar and femoral BMD measurements of male and female subjects were compared. Lumbar and femoral neck BMD values were correlated with the age, weight, height and body mass index of the subjects within each gender groups.
RESULTS: There was no significant difference between mean ages, mean weight, mean height and mean BMI of male and females (P>0.05). The mean lumbar BMD value was statistically higher in pubertal females compared to males (P<0.05). There was significant correlation between the mean age and the mean lumbar BMD measurements in female group (P<0.05). There was significant correlation between the mean weight and the mean BMD measurements (lomber and femoral BMD) in male group (P<0.05).
DISCUSSION AND CONCLUSION: In conclusion, DXA is a useful, fast and accurate diagnostic tool for performing BMD measurements of lumbar spine (L1-4) and femoral neck in pubertal males and females.
