Participants A total of 577 adolescents aged 14 to 19 years.
Main e measures The presentations and diagnoses of adolescents with menstrual
disorders were reviewed and their menstrual es
determined by a telephone survey.
Results In all, 47% presented with menorrhagia, prolonged menstruation,
and short menstrual cycles; 27% had secondary amenorrhoea,
12% had dysmenorrhoea, 11% had oligomenorrhoea, and 3%
had primary amenorrhoea. Significant diagnoses included
congenital genital tract anomalies, premature ovarian failure,
anorexia nervosa, and polycystic ovarian syndrome. Polycystic
ovarian syndrome was diagnosed in 16% of the cohort. In all,
24% of these 577 patients had abnormal menstrual cycles 4
years later. Direct logistic regression analysis indicated a cycle
length of more than 35 days at presentation (adjusted odds
ratio=; 95% confidence interval, -), previous diagnosis
of polycystic ovarian syndrome (adjusted odds ratio=; 95%
confidence interval, -), and current body mass index of
23 kg/m2 or higher (adjusted odds ratio=; 95% confidence
interval, -) were risk factors for persistently long menstrual
cycle exceeding 35 days. Adolescents who were screened out
with a definitive diagnosis after initial assessment were at low
risk of persistently long menstrual cycles at follow-up (adjusted
odds ratio=; 95% confidence interval, -).
Conclusions Adolescent menstrual disorders should not be ignored.
