Eggs are nutrient-dense while also loaded with abundant cholesterol, thus making the public hesitant about their consumption. We conducted the study to investigate if egg consumption is associated with incident cardiovascular disease (CVD) and all-cause mortality. Using the project of Prediction for Atherosclerotic Cardiovascular Disease Risk in China, we included 102,136 adults free of CVD and assessed their egg consumption with food-frequency questionnaires. CVD endpoints and all-cause mortality were confirmed during follow-ups by interviewing participants or their proxies and checking hospital records/death certificates. The HRs (95% CIs) were calculated using the cohort-stratified Cox regression models. During 777,163 person-years of follow-up, we identified 4,848 incident CVD and 5,511 deaths. U-shaped associations of egg consumption with incident CVD and all-cause mortality were observed. Compared with consumption of 3-<6/week, the multivariable-adjusted HRs (95% CIs) of <1/week and ≥10/week for incident CVD were 1.22 (1.11 to 1.35) and 1.39 (1.28 to 1.52), respectively. The corresponding HRs (95% CIs) for all-cause mortality were 1.29 (1.18 to 1.41) and 1.13 (1.04 to 1.24). Our findings identified that both low and high consumption were associated with increased risk of incident CVD and all-cause mortality, highlighting that moderate egg consumption of 3-<6/week should be recommended for CVD prevention in China.
鸡蛋营养丰富,但同时也含有大量胆固醇,这使得公众对其食用持犹豫态度。我们进行了这项研究,旨在探讨鸡蛋的摄入是否与心血管疾病(CVD)事件和全因死亡率有关。我们利用中国动脉粥样硬化性心血管疾病风险预测项目,纳入了 102136 名无 CVD 的成年人,并使用食物频率问卷评估了他们的鸡蛋摄入量。通过对参与者或其代理人进行访谈以及检查医院记录/死亡证明,在随访期间确认了 CVD 事件终点和全因死亡率。使用队列分层 Cox 回归模型计算了 HR(95%CI)。在 777163 人年的随访期间,我们共发现了 4848 例 CVD 事件和 5511 例死亡。鸡蛋摄入与 CVD 事件和全因死亡率呈 U 型关联。与每周食用 3-<6 个鸡蛋相比,每周食用<1 个和≥10 个鸡蛋与 CVD 事件的多变量校正 HR(95%CI)分别为 1.22(1.11-1.35)和 1.39(1.28-1.52)。相应的全因死亡率 HR(95%CI)分别为 1.29(1.18-1.41)和 1.13(1.04-1.24)。我们的研究结果表明,低摄入量和高摄入量都与 CVD 事件和全因死亡率风险增加相关,这表明在中国,推荐中等摄入量(每周 3-<6 个)的鸡蛋摄入有助于预防 CVD。
