Influence of Physiological Factors on Thyroid Size Determined by Ultrasound
According to its superficial anatomical location, the thyroid gland is easily accessible by sonography. Sonography allows an exact documentation of the size and thyroid volume. The relationship between thyroid volume and anthropometric characteristics is a matter of controversy. The aim of this study was to investigate thyroid volume and its determinants in healthy adult. A cross-sectional study was performed from June2003 until April 2005 in 314 healthy adults aged over 18 years old in Yazd, Iran. Data were collected on age, sex, and weight and thyroid size by sonoraphy. Mean of thyroid volume in male and female was 9.08 ± 2.49 and 7.93 ± 3.2 milliliter which the differences was significant (P
