Fifty-nine children aged 18 to 47 months with normal and elevated blood lead levels had bone mineral density (BMD in gm/cm2) and bone mineral content (BMC in gm/cm) measured using the technique of single photon absorptiometry of the radius shaft. No normative data are available for black children of this age group. Moderate elevations of blood lead were not found to influence bone mineralization. The BMC of the study children was significantly higher than the published values for white children of the same age. We found no statistical difference between the bone mineral density of males and females in this age group.
对59名年龄在18至47个月、血铅水平正常及升高的儿童，采用桡骨干单光子吸收测定技术测量其骨密度（单位为克/平方厘米）和骨矿物质含量（单位为克/厘米）。该年龄组黑人儿童尚无标准数据。未发现血铅适度升高会影响骨矿化。研究儿童的骨矿物质含量显著高于已发表的同年龄白人儿童数值。我们发现该年龄组男性和女性的骨密度无统计学差异。
