Age at Menarche and the Menstrual Pattern of Igbo Women of South-east Nigeria

O Umeora, VE Egwuatu


This study determines the age at menarche and menstrual pattern of an Igbo population in 12 randomly selected rural communities of Ebonyi State. Information on recalled ages at menarche, menstrual flow duration and cycle length was collected using a semi structured questionnaire over three months. 1209 women of reproductive age
were interviewed. The mean age at menarche was 15.0 years and this declined over the years. The mean menstrual flow duration and cycle lengths were 3.3 days and 29.7 days respectively. Only 10.2% had a menstrual cycle length of 28 days. Account should be taken of the average length of 29-30 days in the rural Igbo population when calculating
the expected date of delivery and in the family planning clinics.

Keywords: menarche, menstruation, pattern, Igbo, Cycle, recall.
