Abstract:
Objective: Our study described the body composition of 50 preschool children aged from 4 to 6 years old and evaluated their nutritional and developing status. Methods: Body composition was measured with dual energy X ray absorptiometry(DXA). Results: BMC, BMD, FTM, %BF, LTM of all children were (463.3?80.9)g、(0.69?0.04)g/cm 2、(3917.1?1281.6)g、(21.8?4.9)、(13391.4? 1823.8 )g respectively. The relationships between BMC and age and between LTM and age were positively correlated. BMD and LTM of the boys were significantly higher than those of the girls. On the contrary, FTM, %BF, F t/l and F t/a of the girls were obviously greater than those of the boys. Conclusion: DXA method may be used to evaluate the nutritional and developing status in preschool childran.
