Relationship between cardiovascular disease knowledge and race/ethnicity, education, and weight status.

BACKGROUND: Inadequate cardiovascular disease (CVD) knowledge has been cited to account for the imperfect decline in CVD among women over the last 2 decades. HYPOTHESIS: Due to concerns that at-risk women might not know the leading cause of death or symptoms of a heart attack, our goal was to assess the relationship between CVD knowledge race/ethnicity, education, and body mass index (BMI).
METHODS: Using a structured questionnaire, CVD knowledge, socio-demographics, risk factors, and BMI were evaluated in 681 women.
RESULTS: Participants included Hispanic, 42.1% (n = 287); non-Hispanic white (NHW), 40.2% (n = 274); non-Hispanic black (NHB), 7.3% (n = 50); and Asian/Pacific Islander (A/PI), 8.7% (n = 59). Average BMI was 26.3 ± 6.1 kg/m(2) . Hypertension was more frequent among overweight (45%) and obese (62%) than normal weight (24%) (P < 0.0001), elevated total cholesterol was more frequent among overweight (41%) and obese (44%) than normal weight (30%) (P < 0.05 and P < 0.01, respectively), and diabetes was more frequent among obese (25%) than normal weight (5%) (P < 0.0001). Knowledge of the leading cause of death and symptoms of a heart attack varied by race/ethnicity and education (P < 0.001) but not BMI. Concerning the leading cause of death among women in the United States, 87.6% (240/274) NHW answered correctly compared to 64% (32/50) NHB (P < 0.05), 28.3% (80/283) Hispanic (P < 0.0001), and 55.9% (33/59) A/PI (P < 0.001). Among participants with ≤12 years of education, 21.2% knew the leading cause of death and 49.3% knew heart attack symptoms vs 75.7% and 75.5%, respectively, for >12 years (both P < 0.0001).
CONCLUSIONS: Effective prevention strategies for at-risk populations need to escalate CVD knowledge and awareness among the undereducated and minority women.
