Abstract 3147: Community Socioeconomic Status: Effect on the Knowledge of Stroke
Background and Purpose - Despite numerous public awareness campaigns, knowledge about stroke warning signs, risk factors, and treatments remains poor. Previously we described racial disparities in stroke knowledge. We now explore the impact of community socioeconomic status (SES) on stroke knowledge within a large, bi-racial population.
Methods -Survey respondents were contacted via a random-digit dial telephone survey in 2005 from the Greater Cincinnati/Northern Kentucky population. Respondents were asked open-ended questions about stroke with regard to warning signs, risk factors, and treatment with rt-PA. Answers were adjudicated by study physicians.. Community SES was defined as the percentage below poverty level within a respondent’s census tract of residence. There are 346 census tracts in the region. For analysis the SES was stratified into quartiles (percent of residents in census tract living below poverty of <5%. 5%-10%, 10%-25%, and >25%. Univariate and multivariate analyses were performed. Potential covariates were race, sex, education, age, smoking, prior stroke or TIA, and history of high blood pressure, high cholesterol, diabetes, or heart attack. Responses regarding 3 warning signs, 3 risk factors, and knowledge of rt-PA were compared among the different poverty groups.
Results - There were 2156 respondents to the stroke survey. The demographics of the respondents was 24.5 % black, 61.6% women, mean age of 61.5 years. Adjusted odds ratios and 95% confidence intervals are presented in the table. There were no significant differences by community SES of respondents in knowledge of 3 stroke warning signs, 3 risk factors, or of rt-PA.
Conclusion - Community SES does not appear to exert an independent effect on knowledge of stroke warning signs and risk factors, or knowledge of rt-PA as a treatment for stroke. It is likely that education and individual experiences with stroke are more important than community poverty for stroke knowledge. This should inform future interventions for improving stroke knowledge.
