RESULTS
During a decade, the mean menarcheal age decreased from 13.5+/-1.0 to 12.7+/-1.0 years(p=0.001). Gynecologic age, Body mass index were associated with age of menarche in both 1988 and 1998. The interval of menstruation was 30.6 3.5dyas in 1998 and shortened compared with 32.1+/-6.3 days in 1988(p=0.001). The duration of menstruation was lengthened in 1998 than in 1988(6.1+/-1.1 days vs 5.8+/-2.2 days, p=0.001). The incidence of irregular cycle(28.2% vs 58.2%, p=0.001), dysmenorrhea(73.9% vs 77.8%, p=0.001), and secondary amenorrhea(16.2% vs 27.2%, p= 0.001) decreased in 1998 compared with those of 1988. The incidence of agonies about menstruation was also decreased in 1998 than in 1988(26.2% vs 69.1%, p=0.001). The most common agony about menstruation in 1988 was irregular cycle(28.4%), but dysmenorrhea( 64.3%) in 1998.
