Abstract Objective： To analyze the ultrasonic bone mineral density testing results in different gender different in 3 months to 2 years old age group children， provide the basis for clinical prevention of children’s low bone mineral density.Method： Children were attended the outpatient clinic physical examination， and 230 children with 3 months to 2 years old who had been ruled out of bone metabolic diseases were selected. Middle tibia bone density was measured by ultrasonic bone mineral density instrument， according to the same gender， age， bone mineral density of Z value evaluation scores were divided into normal， mild， moderate， severe lack of bone strength. Result： Ji’nan area for 3 months to 2 years old children’s bone strength Z value was（ -0.0439±0.9324）. Bone strength was insufficient detection rate of 16.08%. Girls lack of bone strength detection rate（ 22.01%） was higher than boys（ 10.74%）， the difference was statistically significant（χ2=5.3998，P<0.05）. Different age groups lack of bone strength detection rate： <1 year group（ 31.76%）， 1 year old age group（ 9.87%）， 2 years old age group（ 3.12%）. 3 months - 1 year old age group children lack of bone strength detection rate was higher than 1 year group， the difference was statistically significant（χ2=11.9424，P<0.01）. 1 year old age group of inadequate bone strength detection rate and 2 groups compared with no statistical significance（ χ2=1.5955，P>0.05）. Conclusion： Ji’nan 3 months to 3 years old children’s lack of bone strength detection rate is different， where<1， the highest detection rate of the group， girls were highest， ultrasonic bone mineral density testing for guiding children calcium supplements and the prevention of infantile rickets.
