自本世纪中期始，国内外学者对尿羟脯氨酸进行了较深入的研究。有学者提出，羟脯氨酸指数可较准确地反映尿羟脯氨酸的水平，且可进一步减少个体间的变易程度〔１〕。为了探讨羟脯氨酸指数的临床意义，本文就尿羟脯氨酸指数与儿童营养状况之间的关系进行分析。１　对象与方法１ Since the middle of this century, domestic and foreign scholars have conducted a more in-depth study of urinary hydroxyproline. Some scholars have suggested that hydroxyproline index can more accurately reflect the level of urinary hydroxyproline, and can further reduce the degree of variability between individuals 〔1〕. In order to investigate the clinical significance of hydroxyproline index, this article analyzes the relationship between urinary hydroxyproline index and nutritional status in children. 1 objects and methods 1
