背景和目的为国际比较和规划目的提供卒中和卒中相关残疾患病率的估计。方法从新西兰奥克兰两项相隔10年的基于人群的研究得出患病率估计。第一项是在1981年进行的，包括中风后14年的存活率和与中风相关的残疾的信息，第二项是在1991年至1992年进行的，包括中风后3年的信息。结果总体而言，1991年居住在奥克兰的7491人(3793名男性和3698名女性)(总人口94.5万人)在过去的某个阶段经历过中风。这意味着15岁及以上人口的年龄标准化比率为每10万人中有833人(男性为991人，女性为每10万人706人)。如果只考虑那些康复不完全的人，患病率下降到每10万人中有461人。在这一群体中，三分之一(15岁及以上的10万人中有173人)至少需要一次自我护理活动的帮助。结论通常对中风患病率的估计，包括所有经历过中风的人，可能高估了中风相关残疾的患病率近两倍，因为许多人要么已经康复，要么与中风没有持续的依赖。总体患病率不能提供足够准确的信息来规划和购买为中风患者提供的持续服务。
Background and Purpose To provide estimates of the prevalence of stroke and stroke-related disability for international comparisons and for planning purposes.Methods Estimates of prevalence were derived from two population-based studies conducted 10 years apart in Auckland, New Zealand. The first, carried out in 1981, included information on survival and stroke-related disability to 14 years after stroke, and the second, undertaken in 1991 to 1992, included this information up to 3 years after stroke. An actuarial model was developed that took into account changes in incidence, long-term survival, and population structure.Results Overall, it was estimated that 7491 people (3793 men and 3698 women) living in Auckland (total population 945 000) in 1991 had experienced a stroke at some stage in the past. This represents an age-standardized rate of 833 per 100 000 (991 per 100 000 in men and 706 per 100 000 in women) in the population aged 15 years and older. When only those who have made an incomplete recovery are considered, prevalence falls to 461 per 100 000. Of this group, one third (173 per 100 000 population 15 years and older) required assistance in at least one self-care activity.Conclusions Usual estimates of stroke prevalence, which include all people who have ever experienced a stroke, may overestimate by almost twofold the prevalence of stroke-related disability, since many have either recovered or have no continuing dependency related to stroke. Overall prevalence does not provide information with sufficient precision for planning and purchasing ongoing services for stroke patients.
