An adequate calcium intake and vitamin-D status is important for bone mineralization in adolescents. In Northern China, calcium intake and plasma vitamin-D level of adolescents is low due to low consumption of dairy foods and inadequate sunshine exposure. True fractional calcium absorption (TFCA) in Chinese adolescents has never been performed. This study aims to evaluate nutritional adaptation namely, TFCA and urinary calcium excretion among Chinese adolescents in northern China.
充足的钙摄入量和维生素D水平对青少年的骨骼矿化很重要。在中国北方，由于乳制品消费低和日照不足，青少年的钙摄入量和血浆维生素D水平较低。中国青少年的真实钙分数吸收（TFCA）从未进行过测定。本研究旨在评估中国北方青少年的营养适应性，即TFCA和尿钙排泄情况。
