Menstrual Characteristics of Sickle Cell Disease Patients Seen at a Tertiary Institution in North Western Nigeria

INTRODUCTION: The burden of sickle cell disease (SCD) is high in Sub-Saharan Africa, including Nigeria, and with improved care and survival, reproductive health issues, including menstruation, have become increasingly important and may impact on long-term health and social wellbeing. OBJECTIVES: This study was carried out to characterize the menstrual characteristics of SCD patients. METHODOLOGY: Using a cross-sectional study design, a semi-structured questionnaire was administered and information collected on bio-demographic data, medical history of SCD, reproductive, and menstrual history. RESULTS: One hundred and sixty female patients participated in the study. The mean age was 24.9 years (standard deviation [SD] ± 8.8). The mean age at menarche was 15.6 years (SD ± 2.7) for those menstruating. Most respondents had regular menstrual cycles 120 (82%); normal menstrual cycle lengths 120 (81%) significantly associated with respondent's age (P < 0.05); normal duration of flow 140 (97%); light menstrual flow 104 (71%) significantly associated with body mass index BMI (P < 0.05). Overall, however, 114 (78%) had abnormal menses and 32 (22%) had normal menses. Eighty-one respondents (56%) experienced menstrual pain, which was severe in only 28 cases (35%). The presence of menstrual pain did not significantly affect the annual frequency of crisis (P > 0.05). CONCLUSION: The mean age at menarche was high at 15.6 years. Most respondents had light menstrual flow and overall abnormal menstrual patterns. Menstrual pain was common but was not significantly associated with the frequency of crisis.
