Adolescent pregnancy is currently a significant public health problem in the United States. Because adolescence is a time of increased growth and nutrient demands, pregnancy at this time will have a substantial impact on the calcium requirements of the adolescent. The goal of the proposed research is to address the impact of teenage pregnancy and lactation on the efficiency of calcium absorption, rates of bone calcium turnover and hormonal levels in both non-Hispanic white and non-Hispanic black adolescents.

青少年怀孕目前是美国的一个重大公共卫生问题。 由于青春期是生长发育和营养需求增加的时期，此时怀孕将对青少年的钙需求量产生重大影响。 拟议研究的目标是解决青少年怀孕和哺乳对非西班牙裔白人和非西班牙裔黑人青少年钙吸收效率、骨钙周转率和激素水平的影响。
