Several studies have related cardiovascular disease (CVD) to serum concentrations of copper and zinc but not to their dietary intakes. We thought to examine the association between dietary intakes of copper and zinc with risk of mortality from CVD in a prospective study encompassing 58,646 healthy Japanese men and women aged 40-79 years. The intakes of copper and zinc were determined by a validated self-administered food frequency questionnaire, and their associations with risk of mortality from CVD were evaluated by Cox proportional hazard modelling. During 965, 970 person-years of follow-up between 1989-2009, we documented 3,388 CVD deaths [1,514 from stroke, 702 from coronary heart disease (CHD) and 1,172 from other CVD]. Copper intake was not associated with CHD mortality; however, the multivariable hazard ratios (HRs) with 95% confidence intervals (CIs) for mortality from stroke, other CVD and total CVD in the highest versus the lowest quintiles of copper intake among men were 1.78 (1.16-2.77; P-trend=0.007), 1.61 (1.01-2.81; P-trend =0.03) and 1.63 (1.21-2.33; P-trend=0.001), respectively, and those among women were 1.49 (1.00-2.19; P-trend=0.04), 1.59 (1.09-2.55; P-trend =0.02) and 1.36 (1.06-1.69; P-trend=0.01), respectively. Higher intakes of zinc was inversely associated with mortality from CHD in men; 0.68 (0.58-1.03; P-trend=0.05) but not women; 1.13 (0.71- 1.49; P-trend=0.61). No associations were observed with other mortality endpoints. In conclusion, dietary copper intake was positively associated with mortality from CVD in both genders; whereas, higher dietary zinc intake was inversely associated with mortality from CHD in men but not women.
几项研究表明心血管疾病 (CVD) 与血清铜和锌浓度有关,但与饮食摄入量无关。我们认为在一项包括 58646 名年龄在 40-79 岁的健康日本男性和女性的前瞻性研究中,检查铜和锌的饮食摄入量与 CVD 死亡率之间的关联。铜和锌的摄入量通过经过验证的自我管理食物频率问卷确定,并用 Cox 比例风险模型评估其与 CVD 死亡率风险的关系。在 1989-2009 年期间 965970 人年的随访期间,我们记录了 3388 例 CVD 死亡[1514 例中风,702 例冠心病 (CHD)和 1172 例其他 CVD]。铜摄入量与 CHD 死亡率无关;然而,在男性中,铜摄入量最高五分位与最低五分位相比,中风、其他 CVD 和总 CVD 的多变量危险比 (HR) 及其 95%置信区间 (CI) 分别为 1.78 (1.16-2.77;P-trend=0.007)、1.61 (1.01-2.81;P-trend=0.03)和 1.63 (1.21-2.33;P-trend=0.001),而女性分别为 1.49 (1.00-2.19;P-trend=0.04)、1.59 (1.09-2.55;P-trend=0.02)和 1.36 (1.06-1.69;P-trend=0.01)。较高的锌摄入量与男性 CHD 死亡率呈负相关;0.68 (0.58-1.03;P-trend=0.05),但女性则没有;1.13 (0.71-1.49;P-trend=0.61)。与其他死亡率终点无关联。总之,饮食铜摄入量与两性 CVD 死亡率呈正相关;而较高的饮食锌摄入量与男性 CHD 死亡率呈负相关,但与女性无关。
