Clinical examination of 230 girls was carried out with signs of connective tissue dysplasia (CTD) -174 and without it - 56, the control group consisted of 50 healthy girls with normal menstruation. The correlation analysis between oxyproline excretion and the degree of juvenile dysmenorrhea (JD) in girls with DST showed a strong positive correlation between the free oxyproline content and the severity of dysmenorrhea (r=+0.86±0.25, p<0.02). Therefore, the heavier the degree of dysmenorrhea in girls with CTD, the higher the free oxyproline indexes, and in girls without DST the oxyproline indexes did not change significantly. Detection of increased levels of free oxyproline in daily urine is an indicator of increased collagen decay in the body, and in girls with symptoms of CTD the course of JD is aggravated.
