Résumé

Introduction: Thyroid disorders are among the most common endocrine disorders. Their diagnosis relies on a combination of clinical and biological signs, with hormonal tests playing a central role. The objective of this study was to evaluate the prevalence of thyroid disorders in a population attending a peripheral health facility in Dakar. Methodology: This was a retrospective descriptive and analytical study conducted from April 11, 2023, to April 12, 2024, including 268 patients aged 8 to 88 years who underwent hormone testing (TSH, T3, T4, TRAK, and TPO antibodies). Analyses were performed using immunological and chemiluminescence methods on the MAGLUMI 600 analyzer. Results: The sample comprised 216 women and 52 men, with a mean age of 39.9 ± 16.51 years (range: 8 to 88 years). The prevalence of thyroid dysfunction was 34.89%. Hyperthyroidism accounted for 21.39% of cases and hypothyroidism for 13.5%. Among the autoimmune etiologies, Graves' disease represented 7% and Hashimoto's disease 1.39%. A female predominance and a higher frequency in the 20-40 age group were observed. Conclusion: Thyroid disorders are common in our population, predominantly hyperthyroidism and with a marked female predominance. Early detection remains essential to reduce associated morbidity.
