Association Between the Occurrence of Stroke and Overall Mortality

Abstract

Stroke is an acute type of cerebrovascular disease. While it is known that strokes lead to cardiovascular mortality. However, very little is known about if occurrence of stroke is connected to overall mortality.We analyzed data on adults (≥ 20 years) from the 1999–2010 National Health and Nutrition Examination Survey, which is a population-based survey conducted by the National Center for Health Statistics, with mortality data obtained through December 2019. We assessed for stroke through self-reported data. Due to the complex sampling design, sample weights were utilized in order to analyze the data. Comparisons were analyzed using Pearson's Chi Square, simple, and multivariable Cox regression to determine the relationship of depression and cancer-related mortality. All missing variables were excluded.Data was available for 14,504 adults in the United States population. The percentage of individuals who experienced mortality after stroke was higher among African American population 1.5% (1.21-1.73) than the Hispanic population 0.55% (0.42-0.74). The overall unadjusted hazard ratio for stroke to no stroke was 6.16 (5.32-7.13, p < 0.01). The adjusted HR remained strong at 1.97 (CI 1.74-2.24, p < 0.01) among adults after the results were controlled for medical (obesity) and demographic (gender, age, poverty-income-ratio) risk factors.There is a significant relationship between stroke occurrence and overall mortality among all adults. Consequently, individuals with stroke need better access to prevent this disease through services and overall healthcare. Health care professionals should be made aware of gaps in prevention of stroke.
