Key result
Education under 10 years is linked to ~92% higher odds of insufficient cardiovascular risk knowledge.
Why the study?
The relationship between socioeconomic status and knowledge of cardiovascular risk factors in a general Japanese population was unknown.
Is low socioeconomic status associated with insufficient knowledge of cardiovascular risk factors in a general Japanese population?
Cross-Sectional (n=2,467)
Yes
Is low socioeconomic status associated with insufficient knowledge of cardiovascular risk factors in a general Japanese population?
Odds Ratio: 1.92 (95% CI 1.51–2.45)
Absolute Event Rate: 54.7% vs 43%
Lower socioeconomic status, specifically shorter education and lower household expenditure, is significantly associated with poorer knowledge of cardiovascular risk factors in the Japanese population.
Lower education and EHE linked to poorer CV risk factor knowledge; leaves open whether targeted education narrows gaps in low-SES Japanese adults.
BACKGROUND: The relationship between socioeconomic status (SES) and knowledge of cardiovascular risk factors remains unknown in a general Japanese population. METHODS: Of 8,815 participants from 300 randomly selected areas throughout Japan, 2,467 participants who were free of cardiovascular disease and who provided information on SES in the National Health and Nutrition Survey of Japan 2010 were enrolled in this cross-sectional analysis. SES was classified according to the employment status, length of education, marital and living statuses, and equivalent household expenditure (EHE). Outcomes were ignorance of each cardiovascular risk factor (hypertension, diabetes, hypercholesterolemia, low high-density lipoprotein [HDL] cholesterol, arrhythmia, and smoking) and insufficient knowledge (number of correct answers <4 out of 6). RESULTS: A short education and low EHE were significantly associated with a greater ignorance of most cardiovascular risk factors. A short education (<10 years) was also associated with insufficient knowledge of overall cardiovascular risk factors: age- and sex-adjusted odds ratios (OR) were 1.92 (95% confidence interval [CI], 1.51-2.45) relative to participants with ≥13 years of education. Low EHE was also associated with insufficient knowledge (age- and sex-adjusted OR 1.24; 95% CI, 1.01-1.51 for the lowest quintile vs the upper 4 quintiles). These relationships remained significant, even after further adjustments for regular exercise, smoking, weekly alcohol consumption, body mass index, hypertension, diabetes mellitus, hypercholesterolemia, and low HDL cholesterol. CONCLUSION: Participants with a short education and low EHE were more likely to have less knowledge of cardiovascular risk factors.

Tsuji et al. (2018) conducted a cross-sectional in General population free of cardiovascular disease (n=2,467). Short education (<10 years) vs. ≥13 years of education was evaluated on Insufficient knowledge of overall cardiovascular risk factors (number of correct answers <4 out of 6) (OR 1.92, 95% CI 1.51-2.45). A short education of less than 10 years was significantly associated with insufficient knowledge of cardiovascular risk factors compared to 13 or more years of education (OR 1.92).
