Abstract
The urinary hydroxyproline per unit amount of creatinine (H.P/cre), and height, weight, chest girth and sitting height of girls (12-13 years old) before and after the menarche were investigated. It was found that the mean height, weight, chest girth and sitting height of girls after the menarche were greater than those of girls before the menarche, and the mean H.P/cre of girls after the menarche was significantly lower than that of girls before the menarche, although the mean ages of the two groups of girls were almost the same. The discriminant function between two groups of girls before and after the menarche was constructed using four variables: H.P/cre, height, chest girth and sitting height. When the investigated girls were classified into two groups of girls before and after the menarche by the discriminant function, the percent of girls correctly classified was 95.4%. The discriminating power of the function increased considerably when H.P/cre value was added as discriminating variable to three variables concerning body build. H.P/cre at each month from four months before the menarche to one month after the menarche was examined on 8 girls. The mean value of H.P/cre at four, three and two months before the menarche were significantly greater than that one month immediately before the menarche.
