【摘要】 应用单光于吸收法对正常人209例进行了骨密度的测定。结果表明,增龄因素对儿童骨密度有非常显著的影响(P<0.01)。20岁以后骨密度达到峰值并持续数十年。40岁以后男女性别的骨密度均出现下降,但男性的相应指标下降晚于女性。体重及身高也是影响骨密度的重要因素。更多还原

【Abstract】 Using single - photonabsorbtiometry we measured bone density in 209 normal individuals.The results showed that the factor of age is very significant to the bone density in children (P<0.01) .The bone density reaches peak after 20 years and keeps for decades, then declines after 40 years but male is late compared with female during this course. Weight and height are also important factors that influence the bone density. It is suggested that we must consider all the factors before we make diagnosis.更多还原
