General population knowledge of cardiovascular disease risk factors is limited. Awareness of risks like smoking or being overweight does not always translate into behavior change for heart attack or stroke prevention.

Area of Science:

  • Public Health
  • Cardiovascular Disease Epidemiology
  • Health Behavior Research

Background:

  • Cardiovascular disease (CVD) remains a leading cause of mortality globally.
  • Understanding public knowledge of CVD risk factors is crucial for effective prevention strategies.
  • Gaps in knowledge and behavior may hinder efforts to reduce CVD incidence.

Purpose of the Study:

  • To assess the general population's knowledge of modifiable cardiovascular disease risk factors.
  • To investigate the influence of sociodemographic factors, health perceptions, and existing risk factors on this knowledge.
  • To examine the relationship between cardiovascular risk knowledge and actual health behaviors, and to explore discrepancies.

Main Methods:

  • A cross-sectional study utilizing a random sample of 732 adults from the greater Boston area.

  • Assessment of cardiovascular risk factor knowledge through direct questioning about risk-reducing behaviors for heart attack and stroke.
  • Measurement of sociodemographic variables, self-perceived health status, and physiological cardiovascular risk factors.

    • Main Results:

    • Respondents demonstrated the highest knowledge regarding the impact of exercise and cholesterol on heart disease.
    • Higher levels of knowledge were associated with increased education, being female, and regular exercise.
    • For individuals who smoke or are overweight, awareness of risk did not consistently predict risk-reducing behaviors, indicating a knowledge-behavior gap.

    Conclusions:

    • Public understanding of key cardiovascular disease risk factors like exercise and cholesterol is relatively strong.
    • Educational attainment and demographic factors influence cardiovascular health knowledge.
    • Interventions must address the disconnect between knowing about risks and adopting protective behaviors to effectively reduce cardiovascular disease.
