ABSTRACT
BACKGROUND AND OBJECTIVE: Stroke is one of the leading causes for death and disability worldwide. A better understanding of the perception of modifiable stroke risk factors in the population is the first step to initiate effective prevention strategies on population level. Changes over 5 years in the risk perception in the general population were investigated by two representative surveys in Germany. METHODS: Nationwide programs to screen voluntary participants for stroke risk were undertaken in 1995-1996 and 2000-2001 by the German Stroke Foundation, in cooperation with the health insurance company BARMER and the Sanofi-Synthelabo Company. As part of these programmes two surveys were performed by TNS-EMNID to collect data on population knowledge. A representative sample of the German population was selected and asked to categorize their perception of stroke risk for common vascular risk factors. RESULTS: A total of 8193 participants were interviewed (4081 in 1995-1996 and 4112 in 2000-2001); 43.5% were (3) 50 years of age and 52.5% were female. Hypertension was rated by 68.3% to be in the highest risk category for stroke, followed by smoking (52.3%), hypercholesterolemia (48.0%), overweight (48.0%), excessive alcohol consumption (32.9%) and diabetes (26.6%). The proportion of participants who graded these factors to be important for stroke occurrence was persistently higher in 2000-2001 than in 1995-1996. CONCLUSION: Perception of modifiable risk factors for stroke increased over a 5-year time period in two representative surveys in Germany. The importance of diabetes mellitus as a risk factor for stroke is especially underestimated in the general population.
