我国35岁以上居民脑卒中患病情况和发病年龄

目的 了解我国35岁以上人群脑卒中患病情况及患者发病年龄.方法 利用2002年中国居民营养与健康状况调杏资料,分析不同年龄、性别、地区居民的脑卒中患病率,现存脑卒中患者的首次发病年龄及发病年龄的性别和地区差异等.结果 全国35岁及以上人群脑卒中标化患病率为1111.5/10万,男性为1258.9/10万,高于女性(959.3/10万);城市居民脑卒中标化患病率为1544.8/10万,明显高于农村(758.1/10万);北方地区居民的脑卒中标化患病率(1479.3/10万)明显高于南方(719.6/10万);东、中、西部地区居民的脑卒中标化患病率分别为1469.0/10万、1085.4/10万和614.9/10万.据推算我国35岁及以上人群中有脑卒中患者562.7万例.现存脑卒中患者的发病年龄呈偏态分布,中位数为60岁.32.4%的患者发病在60岁～.发病年龄中位数男性(60岁)和女性(60岁)间差异无统计学意义(χ~2=0.00,P>0.05),城市人群的发病年龄中位数为61岁,晚于农村人群的58岁(χ~2=17.34,P<0.01),东部地区发病年龄中位数(61岁)晚于中部(59岁)和西部地区(57岁)(χ~2=12.92,P<0.01).结论 我国脑卒中患病存在性别及地区差异.现存脑卒中患者中,有1/2以上的患者脑卒中初次发病在60岁以前,即中青年人群.

The prevalence and onset of age of stroke in Chinese adults

Objective To analyze the prevalence and onset of age of stroke in Chinese adults aged 35 years old and above. Methods Data from the 2002 National Nutrition and Health Survey was used to analyze the prevalence of stroke by age, sex, regions, and the differences of onset of age of stroke among the alive patients. Result Standardized prevalence of stroke in Chinese adults aged 35 years old and above was 1111.5 per 100 000,1258.9 per 100 000 in male which was higher than female (959.3 per 100 000). The prevalence of stroke in urban (1544. 8 per 100 000) was higher than that in rural (758. 1 per 100 000). The standardized prevalence of stroke in the north (1479. 3 per 100 000) was significantly higher than that in the south (719. 6 per 100 000). The standardized prevalence of stroke in eastern,central and western region was 1469.0 per 100 000,1085.4 per 100 000,614.9 per 100 000,respectively. It is estimated that there were 5. 627 million patients with stroke aged 35 years old and above in China in 2002. The age at onset of stroke in the alive patients was skewed distribution. Median was 60 years old. The first incidence of stroke within 60 -age group accounted for 32. 4%. The age at onset of stroke was no significantly different between male (60 years old, χ~2 = 0. 00, P > 0. 05) and female ( 60 years old). The median of the age at onset of stroke (61 years old) in urban was higher than that in rural (58 years old,χ~2 = 17. 34,P<0. 01). The median in eastern region was higher than that in central and western regions (57 years old,χ~2 = 12. 92,P< 0. 01).Conclusion The prevalence of stroke was significant different by sex and regions. Among the alive patients, more than half of their first incidence of stroke were before the age of sixties.
