Cardiovascular health knowledge in the United States: findings from the National Health Interview Survey, 1985.
Knowledge of the risk precursors to cardiovascular disease is thought to be a key component of health decision making. Many intervention programs have been aimed at increasing the nation's general knowledge of risk factors for cardiovascular disease, although the determinants of the level of cardiovascular disease knowledge are not thoroughly understood. We examined cardiovascular knowledge in a nationally representative sample of the United States population with data from the 1985 Health Promotion and Disease Prevention supplement of the National Health Interview Survey. Interviews with 12,551 white women, 770 Hispanic women, 2,547 black women, 9,832 white men, 576 Hispanic men, and 1,440 black men were used in this analysis. We constructed a seven-item index for cardiovascular disease knowledge. After adjustment for age and education, white men and women scored higher on the cardiovascular disease knowledge index than either their Hispanic or black counterparts. We also examined the relationships of age, education, income, marital status, access to medical care, geographic region, and seven self-reported cardiovascular disease risk factors to the levels of cardiovascular disease knowledge. Education was the strongest predictor of cardiovascular disease knowledge. The variables examined accounted for a small portion of the variance in knowledge. Levels of cardiovascular disease knowledge were lower among respondents with less education and income, those who were not married, those with less access to medical care, and those who were smokers or physically inactive. Therefore, efforts to improve levels of cardiovascular disease knowledge should be directed toward subgroups.
