Summary

Cancer prevention knowledge significantly influences health behaviors like diet change and screening. Race was not a significant predictor, except Black women smoked less than White women.

Area of Science:

  • Public Health
  • Health Behavior Research
  • Cancer Prevention

Background:

  • Understanding factors influencing cancer prevention behaviors is crucial for public health initiatives.
  • Previous research suggests demographic and knowledge factors play a role in health behaviors.

Purpose of the Study:

  • To examine the influence of cancer prevention knowledge on health behaviors.
  • To assess the role of race as a predictor of health behaviors, considering knowledge variables.

Main Methods:

  • Utilized data from the 1987 National Health Interview Survey Cancer Control Supplement.
  • Employed multivariate logistic regression models to analyze diet change, mammography, stool blood test utilization, and smoking.
  • Included predictors such as race, sex, age, income, dietary concerns, education, and cancer prevention knowledge.

Main Results:

  • Cancer prevention knowledge was a significant predictor across multiple health behaviors.
  • Race was not a significant predictor of health behaviors when knowledge variables were included.
  • An exception was observed: Black women smoked less than White women.

Conclusions:

  • Cancer prevention knowledge is a key determinant of health-related behaviors.
  • Race's influence on these behaviors diminishes when accounting for knowledge levels.
  • Targeted health education may be more effective than race-based interventions for cancer prevention.
