目的探讨云南边境少数民族的疟疾病因,预防和求医知识的关系及其影响因素.方法在清楚地界定三类疟疾知识的好、中、差标准后,通过问卷调查收集资料;资料经统计学分析,以多因素logistic回归分析调整后的比值比(OR)和P值来最终判断三类疟疾知识的联系程度及其它因素的影响效果.结果在所调查的520名对象中,疟疾病因,预防和求医知识评定为好的比例分别是11.5%(95%CI:9.0～14.7),16.0(95%CI:13.0～19.5)和22.5(95%CI:19.0～26.4);三类疟疾知识间密切相关,病因和预防知识较病因和求医知识间的联系程度强;年龄、上学年教和民族是病因和求医知识的影响因素,而预防知识除受年龄影响外,与家庭经济收入相关. 结论边境少数民族的三类疟疾的联系外,不及时和非正规诊治的危害等其它信息也应是疟疾健康教育的内容.“,”Objective To explore knowledge relationship of malaria causes (KMC), prevention (KMP) and seeking treatment (KST) of ethniacl minorities in Yunnan border, and their influencing factors. Methods After good. Moderate and poor standards of the three kinds of malaria knowledge were clearly defined. Data was collected by interview with questionnaires. After statistical analysis, adjusted odds ratio (OR) and P-value produced by multivariate logistic regression were finally used to estimate the connection degree of the three kinds of malaria knowledge and influencing effect of other factors to them. Results Among 520 subjects interviewed, good percentages of KMC and KST were respectively 11.5％ (95％ CI: 9.0 ～ 14.7), 16.0(95％ CI: 13.0 ～ 19.5) and 22.5(95％CI:19.0 ～ 26.4). Three kinds of malaria knowledge were closely associated each other, and the connection between KMP and KMC is stronger than that between KTS and KMC. Age, schooled years and ethnics were influencing factors of KMC and KST. KMP was significantly related to household economic income as well as influenced by age. Conclusion Three kinds of malaria knowledge of border ethnical minorities are urgently needed to be promoted. Health education as well as general education must be taken into account for communities more in malaria endemic areas. Other information, such as risks of using incompletive treatment courses, delayed diagnosis and treatment, should also be messages for malaria health education as well as connection between mosquitoes and malaria.
