Abstract

Background and Purpose-To assess the effects of intensive and moderate public education on knowledge of early stroke symptoms among a general Japanese population. Methods-Information on early stroke symptoms was distributed by leaflet 12× and by booklet twice in an intensive intervention area >22 months, and by leaflet and booklet once each in a moderate intervention area. No distribution occurred in the control area. Before and after the intervention, a mailed survey was conducted in the 3 areas. A total of 2734 individuals, aged 40 to 74 years, who did not select all 5 correct symptoms of stroke in the preintervention survey were eligible for our analysis. Results-The numbers of correct answers selected about stroke symptoms did not differ significantly among the 3 areas in the preintervention survey (P=0.156). In the postintervention survey, the proportions of participants who selected sudden 1-sided numbness or weakness (94.2% in the intensive intervention area, 88.3% in the moderate intervention area, and 89.2% in the control area P<0.001) and sudden severe headache (76.8%, 70.1%, and 70.4%, respectively P<0.001) differed significantly among the 3 areas. After adjustment for confounding factors, the multivariable-adjusted odds ratios (95% confidence intervals) for correctly choosing all 5 symptoms were 1.35 (1.07-1.71) in the intensive intervention area and 0.96 (0.74-1.24) in the moderate intervention area compared with the control area. Conclusions-Our findings suggest that frequent distribution of leaflets and booklets significantly improved the short-term knowledge of community residents about early symptoms of stroke.
