Abstract

Both subclinical and clinical forms of thyroid disease—hypothyroidism and hyperthyroidism—have become more frequent in recent years. The NHANES III Study followed people aged 12 and above over the course of 6 years, and found that the prevalence of hypothyroidism was 4.6% (0.3% clinical and 4.3% subclinical) while the prevalence of hyperthyroidism was 1.3% (0.5% clinical and 0.7% preclinical).
