Table 1.
Anthropometric parameters (Height, Height Z-score, Weight, Weight Z-score and BMI) of Thai children and adolescents (174 boys and 193 girls) for each age group presented as mean±standard deviation (SD).
Figure 1.
Relationships between age vs. BMD of the lumbar spine (BMDLS; grams per cm2), BMAD of the lumbar spine (BMADLS; grams per cm3) and BMD of the total body (BMDTB; gram per cm2) among boys and girls.
The lines show the best- fitted function with the factors age, age2 and age3 (cubic function) for girls and age and age2 (quadratic function) for boys.

Mean bone mineral density of the lumbar spine (BMDLS), bone mineral apparent density of the lumbar spine (BMADLS) and bone mineral density of total body (BMDTB) with standard deviation (SD) in Thai children and adolescents (174 boys and 193 girls) for each age group.
Figure 2.
Relationships between age vs. BMC of the lumbar spine (BMCLS; grams), BMC of the total body (BMCTB; grams), BA of the lumbar spine (BALS; cm2), BA of the total body (BATB; cm2) and lean body mass (LBM; grams) among boys and girls.
The lines show the best- fitted function with the factors age, age2 and age3 (cubic function) for girls and age and age2 (quadratic function) for boys.

Mean and standard deviation (SD) of bone mineral content of lumbar spine (BMCLS), bone area of lumbar spine (BALS), bone mineral content of total body (BMCTB), bone area of total body (BATB) and lean body mass values (LBM) in Thai children and adolescents (174 boys and 193 girls) for each age group.

BMD of the lumbar spine (BMDLS; grams per cm2) and total body (BMDTB; gram per cm2) at different Tanner stages among boys and girls.
*P<0.05, **P<0.01, ***P<0.001 compared with previous Tanner stage.

Figure 4.
Comparison between our current Thai vs. Indian and Chinese BMD normative data in children and adolescents among boys and girls.
These figures were drawn based on data of the mean ± 2SD available from references [15], [17]. The lines show mean ± 2SD. Thai BMDLS values are higher than those of Indian children and adolescent for both genders. Comparing to Chinese children, Thai children have higher BMDTB values for both genders.
