Etiology of Increasing Incidence of Congenital Hypothyroidism in New Zealand from 1993–2010

摘要

Background:Recent reports suggest that the incidence of congenital hypothyroidism (CHT) is increasing in some countries. The etiology of this change is unclear, and it may relate to changes in screening thresholds. We aimed to determine whether the incidence of CHT in New Zealand has changed and whether ethnic-specific rates and the rates of CHT subtypes have also changed.
