title: [Menarche and menstruation problems among teenagers in Oslo 1993].
abstract: Information on menarcheal age, menstruation habits and complaints was collected by means of questionnaires from 193 girls 14-17 years of age. Estimated median menarcheal age was 13.2 years. No statistical significant association was found between menarcheal age and physical activity or body mass. At the time of the data collection, 171 (95%) of the girls reported monthly menstruation while 29 reported loss of menstruation in more than three months during the period after menarche. 96 (52%) reported use of drugs against dysmenorrhoea, mainly paracetamol or non-steroid antiinflammatory drugs.
