We: (1) reviewed the worldwide prevalence of ET in population\u2010based epidemiological studies, (2) derived as precisely as possible an estimate of disease prevalence, and (3) examined trends and important differences across studies. We identified 28 population\u2010based prevalence studies (19 countries). In a meta\u2010analysis, pooled prevalence (all ages) = 0.9%, with statistically significant heterogeneity across studies (I<jats:sup>2<\/jats:sup> = 99%, <jats:italic>P<\/jats:italic> &lt; 0.001). In additional descriptive analyses, crude prevalence (all ages) = 0.4%. Prevalence increased markedly with age, and especially with advanced age. In the meta\u2010analysis, prevalence (age \u2265 65 years) = 4.6%, and in additional descriptive analyses, median crude prevalence (age \u2265 60\u201365) = 6.3%. In one study of those age \u2265 95 years, crude prevalence = 21.7%. Several studies reported ethnic differences in prevalence, although more studies are needed. Greater than one\u2010third of studies show a gender difference, with most demonstrating a higher prevalence among men. This possible gender preference is interesting given clinical, epidemiological, and pathological associations between ET and Parkinson's disease. Precise prevalence estimates such as those we provide are important because they form the numerical basis for planned public health initiatives, provide data on the background occurrence of disease for family studies, and offer clues about the existence of environmental or underlying biological factors of possible mechanistic importance. \u00a9 2010 Movement Disorder Society<\/jats:p>","DOI":"10.1002\/mds.22838","type":"journal-article","created":{"date-parts":[[2010,2,19]],"date-time":"2010-02-19T12:59:55Z","timestamp":1266584395000},"page":"534-541","source":"Crossref","is-referenced-by-count":772,"title":["How common is the most common adult movement disorder?
