The relationship between socioeconomic status (SES) and knowledge of cardiovascular risk factors remains unknown in a general Japanese population.
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).
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.
Participants with a short education and low EHE were more likely to have less knowledge of cardiovascular risk factors.
在日本普通人群中，社会经济地位（SES）与心血管危险因素知识之间的关系尚不清楚。
在日本 300 个随机选定地区的 8815 名参与者中，纳入了 2467 名无心血管疾病且在日本 2010 年国家健康和营养调查中提供 SES 信息的参与者，进行了这项横断面分析。SES 根据就业状况、受教育年限、婚姻和居住状况以及家庭等效支出（EHE）进行分类。结果是忽略了每个心血管危险因素（高血压、糖尿病、高胆固醇血症、低高密度脂蛋白 [HDL] 胆固醇、心律失常和吸烟）和知识不足（答对的正确答案数<6 个中的 4 个）。
受教育程度低和 EHE 低与大多数心血管危险因素的知识缺乏显著相关。受教育程度低（<10 年）也与整体心血管危险因素的知识不足相关：与受教育年限≥13 年的参与者相比，年龄和性别调整后的比值比（OR）为 1.92（95%置信区间 [CI]，1.51-2.45）。EHE 低也与知识不足相关（年龄和性别调整后的 OR 1.24；95% CI，最低五分位数与最高四分位数相比为 1.01-1.51）。即使进一步调整了规律运动、吸烟、每周饮酒量、体重指数、高血压、糖尿病、高胆固醇血症和低 HDL 胆固醇等因素，这些关系仍然显著。
受教育程度低和 EHE 低的参与者更有可能对心血管危险因素的了解较少。
