BACKGROUND: Sickle cell anaemia (SCA) has been shown to have adverse effects on growth and sexual development. Recent Nigerian studies have reported a declining trend in the age of sexual maturation and menarche in haemoglobin AA (HbAA) individuals.
OBJECTIVE: To evaluate the sexual maturation of female patients with SCA aged 10 to 19 years seen at Lagos University Teaching Hospital Idi-Araba, Lagos and Sickle Cell Foundation.
METHODS: It was a cross-sectional study involving 140 girls with SCA (subjects) and an equal number of girls with HbAA (controls) who were matched for age and socio-economic class over a fivemonth period. The evaluation involved anthropometry, calculation of BMI and determination of breast and pubic hair development using Tanner staging.
RESULTS: The mean BMI for the subjects was 17.2±2.39 kg/m2and 20.2±3.09 kg/m2 for the controls (p < 0.001). The mean age at onset of breast development (B2) was 13 ± 0.39 years in the subjects and 10.5 ± 0.51 years in the controls (p < 0.001). The corresponding mean age for pubic hair development (PH2) was also higher at 13.8 ± 0.59 years for the girls with SCA and 10.4 ± 0.51 years for the controls (p <0.001), while menarche was achieved in the subjects at 14.7 ± 1.68 years and in the controls at 12.3 ± 1.33 years (p < 0.001). Upper socioeconomic class was associated with earlier menarche and faster transition from pre-pubertal stage to pubertal stage of sexual maturation in the controls but was not observed in the SCA subjects.
CONCLUSION: Sexual maturity in patients with SCA lagged behind those of the HbAA controls.
