Arenas, H. M., López, V., Arias, D. R., Orozco Hernández, J. P., & Estrada Álvarez, J. M. (2020). Determination of thyroid volume by ultrasound in adult population without thyroid pathology from Pereira - Colombia. Revista Colombiana De Endocrinología, Diabetes &Amp; Metabolismo, 7(1), 5–10.


Introduction: abnormalities in thyroid volume can occur in hyperthyroidism and in hypothyroidism. Reference values for thyroid volume in the Colombian population according to age groups have not been established, so data from other populations with different characteristics is used in clinical practice. This increases the risk of errors in daily clinical practice and leads to equivocal behaviors, so it is important to obtain normal reference values of thyroid size in the population. The aim of this study was to estimate the reference values for normal thyroid volume in the adult population without thyroid abnormality from Pereira city.
Methods: cross-sectional observational study conducted at Clínica Comfamiliar Risaralda, with male and female population over 18 years of age without prior thyroid pathology. Ultrasound scans were performed using a General Electric ultrasound with reference Logiq P5. Descriptive statistics were used for the analysis and reference values were estimated based on age with P2.5-P97.5 centiles using regression in fractional polynomials, recommended for this type of data.
Results: the mean total volume of the thyroid gland in the population was 6.4 ± 2.3 mL. Regression equations in fractional polynomials were estimated for mean values and their corresponding variability in thyroid volume as a function of age. Centiles were obtained by age.
Conclusions: normal thyroid size reference values were obtained in the healthy adult population from Pereira city.
