Association between Family History of Stroke and Stroke Risk: A Community Survey

Abstract

Approximately 20% of the annual 795,000 stroke occurrences in the United States are fatal, and survivors face high-risk of long-term disability. The purpose of this secondary analysis of a cross-sectional survey data was to explore the association between individuals’ family history of stroke and their stroke risk among Minnesota adults attending the State Fair. The primary study sample (n=207) completed a nine-part survey addressing medical history, stroke risk factor knowledge, and the American Stroke Association stroke risk score. Analysis used descriptive summaries and McNemar’s Chi-square test. McNemar’s test indicated a significant association between family history of stroke and an individual’s stroke risk score ( χ2=38.09, p<.001, (n=194)). Of those with and without family history of stroke, 87.1% and 95.5% correctly identified at least one stroke risk factor, respectively. Implications of this secondary data analysis is for nurses to target high-risk populations using primary prevention strategies to reduce stroke occurrence.
