Prospective follow-up of menstrual disorders in adolescence and prognostic factors.Acta Obstet Gynecol Scand. 2008; 87(11):1162-8.AO
Clinical follow-up of menstrual status and eating behavior in grown-up women diagnosed with menstrual disturbance in adolescence.
Prospective follow-up study six years after the initial study.
A youth clinic that is part of the school health system in Stockholm.
Eighty-seven women diagnosed with secondary amenorrhea or oligomenorrhea in adolescence.
Subjects underwent gynecological examination, evaluation of eating behavior and endocrine status.
MAIN OUTCOME MEASURES
Menstrual status and eating behavior changes.
Menstrual disturbances were still present in 62% of the subjects not using hormonal contraception, 59% of which fulfilled the criteria for polycystic ovary syndrome (PCOS). The frequency of persistent menstrual disturbance was significantly more common in women with previous oligomenorrhea than secondary amenorrhea. The occurrence of eating disorders was decreased by half to 31% in women diagnosed with secondary amenorrhea at the initial study, whereas it was unchanged (40%) in women with previous oligomenorrhea. Recovery from anorectic behavior, primarily in the group of secondary amenorrhea, significantly predicted resumption with menses.
Menstrual disturbances and eating disorders were still frequent after six years in a follow-up of women who had menstrual disturbance in adolescence. PCOS was the main cause explaining persistent menstrual disorder, whereas recovery of anorectic eating disorders predicted resumption of menses. The findings call for a continued follow-up of women diagnosed with menstrual disturbance in their teens.
