目的了解东莞外来务工人员对缺血性脑卒中防治知识的认知水平及其知识来源途径。方法 2012年7月至2013年12月按照多阶段随机抽样原则,在东莞市不同企业抽取外来务工人员发放问卷10 000份,调查内容包括被调查者的一般情况、缺血性脑卒中的危险因素、预警信号、诊疗常识和知识来源途径,各项内容采用描述性分析及多因素Logistic回归分析。结果回收有效问卷8 975份,有效应答率为89.75%。缺血性脑卒中危险因素中高血压知晓率最高(61.51%),糖尿病、高脂血症不足50%,其他危险因素知晓率更低;预警信号中“突发肢体麻木或无力”的知晓率最高(53.24%),其他为6.81%~48.96%;在就诊方式上52.03%的人选择立即呼“120”急救;最常见的卒中信息来源为亲属介绍,其次为电视;在人群分层分析上,教育程度与脑卒中知识成正相关关系(rs=0.076,P<0.001),而年龄则成负相关关系(rs=-0.163,P<0.001)。结论东莞外来务工人员缺血性脑卒中防治知识认知水平较低,且低教育程度者、中年务工人员相对更低,应该通过多种途径加强宣教,提高该人群的卒中防治知识水平,从而降低该人群的卒中发病率。 Objective To understand the cognitive level and knowledge sources of migrant workers in prevention and treatment of ischemic stroke in Dongguan. Methods From July 2012 to December 2013, 10 000 questionnaires were collected from migrant workers in different enterprises in Dongguan according to the principle of multistage random sampling. The survey included the general conditions of respondents, risk factors of ischemic stroke , Early warning signals, diagnosis and treatment of common sense and knowledge sources, the content of descriptive analysis and multivariate logistic regression analysis. Results A total of 875 valid questionnaires were collected and the effective response rate was 89.75%. The highest risk of hypertension (61.51%) in ischemic stroke risk factors, less than 50% of diabetes mellitus and hyperlipidemia, and lower risk of other risk factors; the early warning signal of “sudden limb numbness or weakness” The highest rate was 53.24% and the others was 6.81% ~ 48.96%. 52.03% of the people in the way of treatment chose immediate call “120” for first aid. The most common source of stroke information was relatives, followed by television. In the stratified analysis, there was a positive correlation between educational attainment and stroke knowledge (rs = 0.076, P <0.001), while age was negatively correlated (rs = -0.163, P <0.001). Conclusion There is a low cognitive level of prevention and treatment of migrant workers in Dongguan with low educational attainment and relatively low number of middle-aged workers. Therefore, we should step up education in various ways to improve the knowledge of stroke prevention and control in this population. Reduce the incidence of stroke in this population.
