Thyroid<unk> ty is familial. The disease is said to be inherited as a dominant trait since it has been reported that as many as fifty percent of the first degree relatives of patients with some type of<unk>  present with thyroid antibodies in serum. Few studies have even related it to chromosome 21 because of its high correlation with patients with Down syndrome and familial Alzheimer disease. This theory is controversial, since patients with Turner syndrome also present a high prevalence of<unk>  (up to fifty percent). High iodine consumption<unk>  has a higher prevalence in societies that have a higher intake of iodine in their diet, such as the United States and Japan. Also, the rate of lymphocytic infiltration increased in areas where the iodine intake was once low, but increased due to iodine supplementation. “The prevalence of positive serum tests in such areas rises to over 40 percent within 0.5 to 5 years.” Age It has been shown that “the prevalence of positive tests for thyroid antibodies increases with age, with a frequency as high as 33 percent in women 70 years old or older.” The mean age of prevalence in women is higher than in men by one year, (58 and 59 years old respectively).Autoimmune thyroiditis can affect children. It is very rare in children under the age of five, but can occur; it accounts for around 40 percent of cases in adolescents with goiters. People with hypothyroidism over the age of 40 have an increased chance of developing<unk> .
