Abstract Background Because the prevalence of coronary artery calcification is lower among Japanese than among Western individuals, aspects of the Japanese lifestyle might be related to the development of calcification. We aimed to clarify the relationship between coronary artery calcium scores in Japanese patients and various lifestyle factors among the Japanese population. Methods Study subjects were patients aged ≥20 years who underwent multidetector-row computed tomography. A total of 201 patients agreed to take part in this study and answered a questionnaire regarding lifestyle, medical history, and other factors. Results Old age, current and former smoking, sedentary work, short sleep time, coronary artery stenosis, treatment with statins, medical history of cerebrovascular disease, medical history of angina pectoris, medical history of ischemic heart disease, and medical history of dyslipidemia were associated with higher odds ratios than the other factors examined, while the Japanese-style breakfast (e.g. boiled rice, miso soup, grilled fish) was associated with lower odds ratios. Conclusions In this study, smoking, sedentary work, short sleep time, and the Japanese-style breakfast were lifestyle factors related to coronary artery calcification. The lifestyle of Japanese people may be related to coronary calcification.
