BACKGROUND
The incidence of unruptured intracranial aneurysms (UIAs) and the current public health impact may be higher than that reported in previous studies owing to an increase in the elderly population in the United States.
OBJECTIVE
To report the current incidences of UIAs and subarachnoid hemorrhages (SAH) by using a population-based methodology.
METHODS
Statewide estimates of patients admitted with UIAs and SAH were obtained from the data obtained by the Minnesota Hospital Association. We calculated the annual incidences per 100,000 persons by using the 2010 census data from the U.S. Census Bureau. For the denominator, total persons in each year were categorized into 10-year intervals.
RESULTS
The incidences of UIAs and SAH were 15.6 and 7.7 per 100,000 persons, respectively. There were higher incidences of both UIAs and SAH among women (22.5 and 9.6 per 100,000 persons, respectively). The highest incidence of UIAs occurred in those aged between 75 and 84 years (61.6 per 100,000 persons). The highest incidence of SAH occurred in those aged 85 years and older (30.1 per 100,000 persons).
CONCLUSION
An increase in both incidences of UIAs and SAH can be expected owing to the continued increase of the elderly population, particularly women.
背景
由于美国老年人口增加，未破裂颅内动脉瘤（UIA）的发病率及当前对公共卫生的影响可能高于先前研究报告的水平。
目的
采用基于人群的方法报告UIA和蛛网膜下腔出血（SAH）的当前发病率。
方法
从明尼苏达医院协会获取的数据中获得全州UIA和SAH患者的估计数。我们使用美国人口普查局2010年的人口普查数据计算每10万人的年发病率。对于分母，每年的总人数按10年间隔进行分类。
结果
UIA和SAH的发病率分别为每10万人15.6例和7.7例。女性中UIA和SAH的发病率均较高（分别为每10万人22.5例和9.6例）。UIA发病率最高的是75至84岁人群（每10万人61.6例）。SAH发病率最高的是85岁及以上人群（每10万人30.1例）。
结论
由于老年人口尤其是女性人口持续增加，预计UIA和SAH的发病率都会上升。
