The few studies that have assessed the association between rice intake and mortality have generated inconsistent results. We assessed whether rice intake was associated with cardiovascular disease (CVD) mortality, cancer mortality and all-cause mortality in a prospective cohort of the Chinese population.
We prospectively studied 2,832 adults aged 20 years and above with a mean follow up of 10 years. Rice intake was measured by a 3-day weighed food record (WFR) in 2002. Hazard ratios (HRs) and 95% CI were calculated by competing risks regression (CVD and cancer mortality) and Cox proportional hazards analysis (all-cause mortality).
We documented 184 deaths (including 70 CVD deaths and 63 cancer deaths) during 27,742 person-years of follow-up. No association between rice intake and all-cause mortality was found. After adjusting for sociodemographic and lifestyle factors as well as energy and fat intake, HRs for CVD mortality across tertiles of rice intake were 1.00,0.47 (95% CI 0.25-0.87), and 0.49 (95% CI 0.21-1.13) (p for trend 0.049).
There was no association between rice intake and all-cause mortality.
少数评估大米摄入量与死亡率之间关联的研究得出了不一致的结果。我们在中国人群的前瞻性队列中评估了大米摄入量与心血管疾病（CVD）死亡率、癌症死亡率和全因死亡率之间是否存在关联。
我们对2832名20岁及以上的成年人进行了前瞻性研究，平均随访10年。2002年通过3天称重食物记录（WFR）来测量大米摄入量。通过竞争风险回归（CVD和癌症死亡率）和Cox比例风险分析（全因死亡率）计算风险比（HRs）和95%置信区间（CI）。
在27742人年的随访期间，我们记录了184例死亡（包括70例CVD死亡和63例癌症死亡）。未发现大米摄入量与全因死亡率之间存在关联。在调整了社会人口统计学和生活方式因素以及能量和脂肪摄入量后，大米摄入量三分位数组的CVD死亡率HRs分别为1.00、0.47（95%CI 0.25 - 0.87）和0.49（95%CI 0.21 - 1.13）（趋势p值为0.049）。
大米摄入量与全因死亡率之间不存在关联。
