Soy and soy products are popular ingredients in the Japanese diet. This study aimed to determine whether soy or soy products intake was associated with all-cause mortality in a community-based cohort in Japan. A total of 11 066 participants were obtained from an annual community-based health examination program. A self-administered questionnaire was used to collect information concerning soy and soy products intake and potential confounding factors. Associations between soy and soy products intake and all-cause mortality were assessed using hazard ratios (HRs). After adjusting for all factors, morality was significantly higher in men with infrequent soy intake (HR = 1.53; 95% confidence interval [CI] = 1.13-2.07) and with almost daily intake (HR = 1.55; 95% CI = 1.19-2.03) compared with intake 1 to 2 times per week. Cancer mortality was higher among men who reported rarely eating soy (HR = 1.74; 95% CI = 1.08-2.79). Soy products intake was not statistically significantly associated with all-cause mortality in both sexes.
大豆及豆制品是日本饮食中常见的食材。本研究旨在确定在日本一个社区队列中，摄入大豆或豆制品是否与全因死亡率相关。总共11066名参与者来自一项年度社区健康检查项目。通过一份自填式问卷收集有关大豆及豆制品摄入量和潜在混杂因素的信息。使用风险比（HRs）评估大豆及豆制品摄入量与全因死亡率之间的关联。在对所有因素进行调整后，与每周摄入1至2次相比，很少摄入大豆的男性死亡率显著更高（HR = 1.53；95%置信区间[CI] = 1.13 - 2.07），几乎每天摄入大豆的男性死亡率也显著更高（HR = 1.55；95% CI = 1.19 - 2.03）。报告很少食用大豆的男性癌症死亡率更高（HR = 1.74；95% CI = 1.08 - 2.79）。大豆制品摄入量在两性中与全因死亡率均无统计学显著关联。
