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.

D012016	Reference Values	The range or frequency distribution of a measurement in a population (of organisms, organs or things) that has not been selected for the presence of disease or abnormality.

D012044	Regression Analysis	Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.
