Abstract

Background— Lower-extremity peripheral arterial disease (PAD) is associated with decreased functional status, diminished quality of life, amputation, myocardial infarction, stroke, and death. Nevertheless, public knowledge of PAD as a morbid and mortal disease has not been previously assessed. Methods and Results— We performed a cross-sectional, population-based telephone survey of a nationally representative sample of 2501 adults ≥50 years of age, with oversampling of blacks and Hispanics. The survey instrument measured the demographic, risk factor, and cardiovascular disease characteristics of the study population; prevalent leg symptoms; PAD awareness relative to atherosclerosis risk factors and other cardiovascular and noncardiovascular diseases; perceived causes of PAD; and perceived systemic and limb consequences of PAD. Respondents were 67.2±12.6 years of age with a high prevalence of risk factors but only a modest burden of known coronary or cerebrovascular disease. Twenty-six percent of respondents expressed familiarity with PAD, a rate significantly lower than that for any other cardiovascular disease or atherosclerosis risk factor. Within the “PAD-aware” cohort, knowledge was poor. Half of these individuals were not aware that diabetes and smoking increase the risk for PAD; 1 in 4 knew that PAD is associated with increased risk of heart attack and stroke; and only 14% were aware that PAD could lead to amputation. All knowledge domains were lower in individuals with lower income and education levels. Conclusions— The public is poorly informed about PAD, with major knowledge gaps regarding the definition of PAD, risk factors that lead to PAD, and associated limb symptoms and amputation risk. The public is not aware that PAD imposes a high short-term risk of heart attack, stroke, and death. For the national cardiovascular disease burden to be reduced, public PAD knowledge could be improved by national PAD public education programs designed to reduce critical knowledge gaps.

  • Awareness about PAD is low in the general population but especially among Black Americans.

    “In addition, awareness about PAD is low in the general population but especially among Black Americans.”

    From Racial and Ethnic Disparities in Peripheral Artery Disease (2021) · cites this paper as [45]

    The Knowledge of Risk Factors section reports low PAD awareness—about 25%—and the Ethnicity, Socioeconomic Status, Gender, and Health Disparities section reports lower awareness among nonwhite respondents. The paper does not establish the claim specifically for Black Americans rather than nonwhite respondents as a group. Its survey also covered adults aged 50 or older, not the general population of all ages. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • In a sample of 2501 adults over the age of 50 years, 15.2% of NHW and 12.1% of Hispanics knew that PAD can lead to amputation, whereas only 6.2% of Black Americans surveyed knew this.

    From Racial and Ethnic Disparities in Peripheral Artery Disease (2021) · cites this paper as [45]

    Table 5 (shown in the Predictors of PAD Awareness section; page unavailable) gives the stated amputation percentages for white, Hispanic, and Black respondents. But its heading specifies that these percentages are among respondents aware of PAD, not all 2501 adults surveyed. The Sample and Survey Design section also defines the sample as adults aged 50 or older, rather than over 50. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
