Only one-quarter (26%) of surveyed African-Americans with other risk factors perceived their CKD risk to be higher than average.
Chart Explanation: Shown is the respondents’ perceived risk for kidney disease. Only one-quarter of respondents with kidney disease or one or more of its risk factors perceived their CKD risk to be “higher than average”; those with risk factors were more likely to rate themselves at “higher than average” risk for CKD, compared to respondents with no risk factors (25.6% vs. 8.0%). However, those with risk factors were also slightly more likely to rate themselves at “lower than average” risk for CKD than those without risk factors (52.8% vs. 48.2%).
The National Kidney Disease Education Program (NKDEP; http://www.nkdep.nih.gov/) surveyed 2,017 African-Americans aged 30+ in seven U.S. cities (Atlanta, GA; Baltimore, MD; Cleveland, OH; Jackson, MS; New Orleans, LA, St. Louis, MO; Memphis, TN) regarding knowledge of CKD and its risk factors. Females and college graduates were over-represented relative to the U.S. population of African-Americans.
In the period February-April 2003, the National Kidney Disease Education Program (http://www.nkdep.nih.gov/) surveyed 2,017 (of 4,761 eligible households, cooperation rate 42.2%) African-Americans aged 30+ in seven U.S. cities (Atlanta, GA; Baltimore, MD; Cleveland, OH; Jackson, MS; New Orleans, LA, St. Louis, MO; Memphis, TN) regarding knowledge of CKD and its risk factors (Waterman, Browne, Waterman, Gladstone, & Hostetter, 2008). Females and college graduates were over-represented (72.4% and 37.9%, respectively) relative to the U.S. population of African-Americans. A total of 903 respondents (44.8%) reported having kidney disease or one or more of its risk factors: 13.4% with diabetes, 34.5% with hypertension, 11.2% with family history of kidney disease, and only 1.1% with kidney disease, indicating that those with kidney disease may be underrepresented in this survey population. Participants were asked several open-ended questions, including: “In your opinion, what are the three most serious health problems facing African-Americans today?”; “Have you ever heard of an illness called kidney disease?”; “Can you tell me what you think kidney disease is?”; “How would someone know they have kidney disease?”; “Do you know what kind of tests a person can have to test for kidney disease?”; “Who do you think is more likely to get kidney disease or is at a higher risk for kidney disease?”. Participants were also asked about their perceived risk: “How would you rate your risk for getting kidney disease? Would you say it is higher than average, lower or about average?”
