Abstract

Background: The prevalence of heart disease in East Java is 1.6%, which is above the national prevalence of 1.5%. This study aimed to identify factors associated with knowledge of coronary heart disease prevention among adolescents.

Subjects and Method: This was a cross-sectional study conducted in Mojolangu Village, Malang, East Java. A random sample of 80 adolescents aged 12-19 years were selected for this study. The dependent variable was knowledge of coronary heart disease prevention. The independent variables were age, gender, education, family income, social environment, and information resources. The data were collected by questionnaire and analyzed by logistic regression.

Results: Knowledge increased with female gender (OR= 1.32; CI 95%= 2.67 to 0.02; p= 0.005), higher education (OR= 17.92; CI 95%= 23.12 to 12.72; p <0.001), and higher family income (OR= 2.73; CI 95%= 4.65 to 0.82; p= 0.005). Knowledge increased with good social environment (OR= 1.15; CI 95%= 0.44 to 2.74; p= 0.156) and adequate information resources (OR= 2.06; CI 95%= 0.38 to 4.51; p= 0.098), but they were both statistically non-significant. Knowledge decreased with age (OR= 0.40; CI 95%= 4.28 to 5.09; p= 0.866), but it was statistically non-significant.

Conclusion: Female, higher education, and higher family income are associate with better knowledge of coronary heart disease prevention.
