脑梗塞住院病人病死率与性别、年龄及时间关系

An Analysis of the Relationships Between the Fatality Rate of 3377 Cerebral Infarction Patients and Sex,Age and Time

目的：分析因脑梗塞住院病人的病死率与性别、年龄及时间的关系。方法：对１９９６年１月１日到１９９７年１２月３１日出院的３３７７例（男２１１０例，女１２６７例）脑梗塞病人依性别各分为３个年龄组：老年组，老年前期组和青壮年组，通过χ２检验比较两性别组之间、每性别３个年龄组之间、每年龄组内两性别之间病死率和两性别３个年龄组之间各周病死率。结果：①脑梗塞病死率女性高于男性（Ｐ＜０．０５）。②各性别３个年龄组之间脑梗塞病死率为老年组＞老年前期组＞青壮年组，但无差异性（Ｐ＞０．０５）。③３个年龄组内脑梗塞病死率均为女性大于男性，但无差异性（Ｐ＞０．０５）。④各性别脑梗塞病人每周病死率在３个年龄组之间无差异性（Ｐ＞０．０５）。结论：性别。

Objective:To analyze the relationships between the fatality rate of cerebral infarction and sex,age and time.Method:3 377 cases(male 2 110,female 1 267) of cerebral infarction discharged from 01/01/1996￣12/31/1997 were investigated.All cases was divided into three age groups by sex:senile group,presenile group and young group.The fatality rates of cerebral infarction between two sex groups,among the three age groups in each sex,between the two sex groups in each age group and among the three age groups in each sex on every week were analyzed by χ 2 test.Results:①The fatality rate of cerebral infarction in female was significantly higher than in male( P <0 05).②In each sex the fatality rates of cerebral infarction in the three age groups,the senile group>presenile group>young group,there were no significant difference( P > 0.05 ).③In three age groups the fatality rates of cerebral infarction in female were higher than in male,there were no significant difference( P >0 05).④The fatality rates of cerebral infarction on every week in each sex,there were no significant difference among three age groups( P >0 05).Conclusions:It was possible that age,sex and time have some different effects on the fatality rate of cerebral infarction.
