Purpose
Hypothyroidism has been reported at a prevalence of 6% in children and adolescents with Sickle cell anemia. In this study, we determined the prevalence and factors associated with hypothyroidism among children with Sickle cell anemia attending the Sickle Cell Clinic, in Mulago hospital, Uganda.
Methods
A cross-sectional study was conducted among children aged 6 months − 17 years with a confirmed diagnosis of Sickle Cell Anemia, with no prior diagnosis of hypothyroidism and in steady state attending the Sickle Cell Clinic in Mulago hospital. Data was collected using a structured questionnaire and a blood sample was used to measure thyroid stimulating hormone and free thyroxine.
Results
Of the 332 children enrolled, sixty (18.1%) participants had sub-clinical hypothyroidism (95% CI: 14.3 — 22.6). Factors associated with hypothyroidism included constipation [adjusted odds ratio: 3.1, 95% CI:1.0 — 9.0, p = 0.043] and male sex [adjusted odds ratio:2.0, 95% CI:1.1— 3.5, p = 0.025].
Conclusion
Approximately 1 in 5 children (18.1%) had sub-clinical hypothyroidism. Males and children who presented with constipation were more likely to have sub-clinical hypothyroidism.
