Abstract

Four Hundred and fifteen post menareheal secondary school girls selected randomly from six secondary schools in Maiduguri metropolis were interviewed with the aid of questionnaires to find out their age s at menarche and associated menstrual problems, regularity of menstrual cycle, menorrhagia and dysmenorrhoe a within the first two years following menarche. Their ages ranged between 12 and 21 years. Twenty six students were three months post menarche, 187 were 4-1 2 months post menarche. 'The mean menareheal age was 13.6 years. Menorrhagia was a very rare form of menstrual abnormality. Early menarche especially between the age s of 12 to 14 years was found to be associated with higher frequency of irregular menstrual cycles while this improves with late onset menarche. About 45% had one form of menstrual abnormality, amenorrhoea (4.6%), oligomenorrhoea (18% ) and polymenorrhoea (21%). These were almost uniformly associated with all groups. Over 8 0% had attained menarche by age of 14 years. Dysmenorrhoea was just slightly commoner by the ages of 15 and 16 years when it occurs more frequently.
