Abstract
Objective To evaluate the bone mineral density (BMD) in obese young adults. Methods Sixty obese adolescents (26 males and 34 females) who visited outpatient clinic for obesity were enrolled in study (obese group) and 60 age- and sex-matched normal medical students served as control group. Subjects with secondary obesity and metabolic bone disease were excluded from the study. The BMD and bone mineral contents ( BMC) were measured by dual-energy X-ray absorptiometry for whole body, at arms, ribs, thoracic spines, lumbar spines, pelvis, legs and head. Results The overall BMC and BMD of obese group was higher than those of control group (P < 0.05). BMC in non-load-bearing bones (ribs, thoracic spine and head) of obese was higher than that of control group (P < 0. 05), but there was no difference in BMD between two groups (P > 0.05). Both BMC and BMD in load-bearing bones (arms, lumbar spine, pelvis, legs) of obese group was higher than those of control group (P <0.05). Conclusion The BMC and BMD of load-bearing bones in obese adolescent are related to their body weight; after adjustment for lean mass, there are no differences in BMC and BMD between obese and normal young adults. The results suggest that obese patients should reinforce exercise during body weight control, in order to reduce the loss of bone mass
