Objective To study the influencing factors of cerebrovascular function in the elderly in the community,and to provide the evidence for stroke risk assessment and prevention.Methods A total of 5 447 people aged 60 and over in the community were selected as the study subjects,and the cerebrovascular function test was performed to obtain the cerebrovascular function score.At the same time,the risk factors of stroke were investigated,measured and detected.The subjects were divided into normal cerebrovascular function group and abnormal function group,and the relationship between exposure of various risk factors and cerebrovascular function was analyzed.Results Univariate analysis showed that there was a significant correlation between the exposure of female,atrial fibrillation,hyperuricemia,systolic blood pressure,diastolic blood pressure,fasting blood glucose,triglyceride,BMI and other risk factors and whether the cerebrovascular function was abnormal（P＜0.05）.Multivariate logistic regression analysis showed that the abnormal cerebrovascular function was mainly affected by factors such as systolic blood pressure,diastolic blood pressure,fasting blood glucose,triglycerides,and BMI.Conclusion The abnormality of cerebrovascular function is closely related to the exposure of risk factors such as blood pressure,fasting blood glucose,triglyceride,BMI,and is the result of the comprehensive effect of risk factors.

目的 调查农村地区首次流感疫苗接种中的老年人构成比。方法 对近4年来(2017年1月至2020年12月)在本社区卫生服务中心首次流感疫苗接种人数回顾性调查，按年度统计出接种总人数及老年人接种人数，比较各年度老年人接种的构成比，分析近4年来老年人流感疫苗接种的动态变化。结果 近4年来我中心流感疫苗接种人群中仍以非老年人群为主，但所占的百分比有逐渐降低趋势，差异有统计学意义(c2=26.07，P=0.00)。近4年来本中心老年流感疫苗接种人群在性别(c2=1.25，P=0.26)、地域(c2=0.58，P=0.45)方面差异无统计学意义。结论 近4年来本地区农村老年人流感疫苗接种人数增加，但接种人群及构成比仍较低有待提高。

目的:了解奉贤区中小学生运动伤害发生状况及其影响因素.方法:采用分层整群抽样方法抽取区内8所学校的3327名学生,男生1721人,女生1606人,小学生1401人,初中生1112人,高中生814人.采用问卷调查学生过去一年运动伤害发生情况.结果:奉贤区中小学生运动伤害发生率5.9%,男生运动伤害发生率高于女生(7.7%:4.0%,P<0.05);初中生运动伤害发生率为9.4%,高于小学生的5.3%和高中生的2.3%(P<0.05).发生运动伤害的主要部位是下肢(29.4%).有28.9%的学生因运动伤害的平均缺课6.5天;运动伤害主要发生时间是学校体育课(42.1%);运动伤害时主要体育活动是球类(37.1%)和田径类(27.9%).运动伤害发生的主要原因包括思想麻痹和注意力不集中(23.9%),准备活动不充分(21.3%),技术不熟练和动作不规范(18.3%).结论:初中生和男生是运动伤害的重点人群,应针对学生运动伤害流行特点,采取综合干预措施,以降低中小学生运动伤害的发生.
