Effects of strengthening public education by television on awareness of early stroke symptoms among rural communities

目的探讨强化公共影视教育对提高农村社区早期脑卒中认知的价值。方法 2012年3月~2013年3月,在连云港市赣榆县分别选择3个活动村(干预组)和3个对照村(对照组),干预组接受每3个月1次、连续4次的脑卒中早期症状知识的强化影视教育,对照组不参加影视教育。活动前后,两组随机抽取40~75岁的常住居民,通过电话回答脑卒中早期症状问卷,比较干预前后两组问卷积分等级人数百分比,并按性别分层统计问卷及格率及其95%CI。结果干预前两组的积分等级人数分布相似(χ~2=0.478,P=0.924),经过1年的强化影视教育,干预组各等级积分均明显提升(χ~2=96.007,P=1.65×10^(-9))。强化影视教育后,全组问卷及格率女性(89.3%)显著高于男性(71%)(95%CI:0.784~1.000,95%CI:0.652~0.804%,P<0.001),经年龄、文化程度、人均年收入和社区距县城的距离之多元参数调整后的结果相似。干预组问卷积分与参加次数间呈显著正相关关系(n=287,r=0.2273,P=0.0004)。结论农村社区强化影视教育活动能有效提升40~75岁的中国农村社区居民的脑卒中认知,特别是对女性,接受教育的次数越多效果越好。

Objective To explore the effects of strengthening public education by television on awareness of early stroke symptoms among rural communities. Methods Three communities（ intervention group） and control communities（ control group） were selected from Ganyu County,Lianyungang City between March 2012 and March2013,the intervention group was given intensive television education on knowledge of early symptoms of stroke once every 3 months,four consecutive times,while the control group was not. Before and after the campaign,residents aged 40 to 70 years were selected randomly from two groups and answered a telephone survey regarding knowledge of early stroke symptoms. Percentage of the people number of questionnaire grades in the two groups were compared,also the pass questionnaire rate and 95% CI were calculated after sex stratification. Results The distribution of the people number of questionnaire grades was similar before the intervention（ χ~2= 0. 478,P = 0. 924）,but the intervention group improved significantly each grades after 1 year intensive television education campaign（ χ~2= 96. 007,P =1. 65 × 10^（- 9））. After television education,the pass questionnaire rate of female（ 89. 3%） was significantly higher than male（ 71%）（ 95% CI： 0. 784- 1. 000%,95% CI： 0. 652- 0. 804,P〈0. 001）,referring to the per-intervention.These data were still similar after adjusted for age,educational level,per capita income and the distance from the country seat of the community. The questionnaire score of intervention group and the times has a significant postitive correlation（ n = 287,r = 0. 2273,P = 0. 0004）. Conclusions The intensive television educational in rural community can effectively improve knowledge about early stroke symptoms among the residents aged 40 to 70 years,especially in female. The more participate times,the better education effect.
