A two-phase epidemiological study of essential tremor was carried out by investigating a rural population aged over 40 years in 2 municipalities in southwestern Finland. In the first phase, the subjects answered a questionnaire as to whether they had experienced tremor during the month preceding the inquiry. In the second phase, the persons who had tremor often or fairly often, were examined clinically. The total prevalence of essential tremor, calculated on the basis of clinically established cases, was 55.5/1000 of the population aged over 40 years. The disease became more prevalent with advancing age and was, with the exception of the oldest age-group, more common in men than in women.
通过对芬兰西南部两个城市中40岁以上农村人口进行调查，开展了一项关于特发性震颤的两阶段流行病学研究。在第一阶段，受试者回答一份关于在询问前一个月内是否经历过震颤的问卷。在第二阶段，对经常或相当频繁出现震颤的人进行临床检查。根据临床确诊病例计算，特发性震颤在40岁以上人群中的总患病率为55.5/1000。该疾病随着年龄增长而更加普遍，除了最年长的年龄组外，男性比女性更常见。
