BACKGROUND & AIMS: Previous studies on the association between skipping breakfast and risk of cardiovascular disease and all cause mortality have drawn controversial conclusions. Therefore, we carried out a meta-analysis to illuminate this association.
Studies about the association between skipping breakfast and risk of cardiovascular disease and all cause mortality were identified by searching Pubmed, Embase, Cochrane, and Web of Science databases until June 2019. Then we screened articles for eligibility, extracted data, and pooled the results using a random-effects model.
Seven cohort studies concerning a total of 221,732 participants were included in this meta-analysis. Skipping breakfast was associated with elevated risk of cardiovascular disease (relative risk 1.22 95% confidence interval 1.10-1.35) and all cause mortality (relative risk 1.25 95% confidence interval 1.11-1.40) compared with eating breakfast regularly.
Skipping breakfast increases the risk of cardiovascular disease and all cause mortality. Eating breakfast regularly may promote cardiovascular health and decrease all cause mortality.
关于不吃早餐与心血管疾病和全因死亡率风险之间的关联的先前研究得出了有争议的结论。因此，我们进行了荟萃分析以阐明这种关联。
通过检索 Pubmed、Embase、Cochrane 和 Web of Science 数据库，直到 2019 年 6 月，确定了关于不吃早餐与心血管疾病和全因死亡率风险之间关联的研究。然后，我们筛选文章以确定其合格性，提取数据，并使用随机效应模型汇总结果。
本荟萃分析共纳入了 7 项队列研究，总计 221732 名参与者。与规律吃早餐相比，不吃早餐与心血管疾病风险增加（相对风险 1.22，95%置信区间 1.10-1.35）和全因死亡率（相对风险 1.25，95%置信区间 1.11-1.40）相关。
不吃早餐会增加心血管疾病和全因死亡率的风险。规律吃早餐可能有助于促进心血管健康并降低全因死亡率。
