To analyze the prevalence and onset of age of stroke in Chinese adults aged 35 years old and above.
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.
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, chi(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, chi(2) = 17.34, P < 0.01). The median in eastern region was higher than that in central and western regions (57 years old, chi(2) = 12.92, P < 0.01).
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.
分析35岁及以上中国成年人中风的患病率及发病年龄。
利用2002年全国营养与健康调查的数据，按年龄、性别、地区分析中风患病率，以及存活患者中风发病年龄的差异。
35岁及以上中国成年人中风的标准化患病率为1111.5/10万，男性为1258.9/10万，高于女性（959.3/10万）。城市中风患病率（1544.8/10万）高于农村（758.1/10万）。北方中风的标准化患病率（1479.3/10万）显著高于南方（719.6/10万）。东部、中部和西部地区中风的标准化患病率分别为1469.0/10万、1085.4/10万、614.9/10万。据估计，2002年中国35岁及以上中风患者有562.7万。存活患者中风发病年龄呈偏态分布。中位数为60岁。60岁及以下年龄组首次中风发生率占32.4%。男性（60岁，χ² = 0.00，P > 0.05）和女性（60岁）中风发病年龄无显著差异。城市中风发病年龄中位数（61岁）高于农村（58岁，χ² = 17.34，P < 0.01）。东部地区中位数高于中部和西部地区（57岁，χ² = 12.92，P < 0.01）。
中风患病率在性别和地区上存在显著差异。在存活患者中，超过一半的首次中风发生在60岁之前。
