Analysis of the bone mineral density and related factors in youth health physical examination

Objective To analyze the bone mineral density(BMD) of people aged younger than 45 yrs to know peak bone mineral density in order to prevention osteoporosis.Methods 235 health physical people was measured BMD by dual energy X-ray absorptiometry,reported as Z scores for height.Comparison of correlation between BMD and sex,age,body mass index(BMI),lifestyle factors.Results In 235 cases of young healthy population,136 were male,99 were female,abnormal rate of BMD was respectively 19.1%,25.3%,no statistically significant differences.the mean of BMD was 1.49 ± 2.30,0.81 ± 1.78 respectively.The difference was statistically significant(P 0.05).Analysis of related factors of BMD,body mass index(BMI),regular drinking milk were bone protective factors,habitual drinking coffee or strong tea were risk factors.Conclusions Youth with low bone mass phenomenon should cause height to take seriously,to the timely monitoring,timely intervention,develop healthy working and living habits,is conducive to the prevention of osteoporosis and its complications.
