A systematic review and meta-analysis of prospective cohort studies was conducted to examine the association of potato consumption and risk of all-cause, cancer and cardiovascular mortality in adults. We searched PubMed, Scopus databases up to September 2018 for all relevant published papers. All analyses were performed on HRs or RRs and 95% CIs. In twenty prospective studies, 25,208 cases were reported for all-cause mortality, 4877 for cancer mortality and 2366 for CVD mortality. No significant association was found between potato consumption and risk of all-cause (0.90; 95% CI: 0.8, 1.02, p = 0.096) and cancer (1.09; 95% CI: 0.96, 1.24, P = 0.204) mortality. In addition, no significant linear association was found between each 100 g/d increments in potato consumption and risk of all-cause (P = 0.7) and cancer (P = 0.09) mortality. Moreover, nonlinear association between potato consumption and risk of cancer mortality was non-significant (P-nonlinearity = 0.99). In addition, two of three studies which examined the association of potato consumption with CVD mortality did not find any significant relationship. There was no evidence for publication bias in this study. We failed to find significant association between potato consumption and risk of mortality. Further studies are required to confirm this issue.

马铃薯食用量及所有原因，癌症和心血管疾病死亡率的风险：前瞻性队列研究的系统评价和剂量反应荟萃分析。

对前瞻性队列研究进行了系统的回顾和荟萃分析，以研究马铃薯消费与成人全因，癌症和心血管疾病死亡率风险之间的关系。我们搜索了截至2018年9月的PubMed，Scopus数据库以查找所有相关已发表的论文。所有分析均针对HR或RR和95％CI。在20项前瞻性研究中，报告的全因死亡率为25208例，癌症死亡率为4877例，CVD死亡率为2366例。食用马铃薯与全因风险（0.90; 95％CI：0.8，1.02，p = 0.096）和癌症（1.09; 95％CI：0.96，1.24，P = 0.204）死亡率之间无显着关联。此外，在马铃薯食用量每增加100 g / d与全因风险（P = 0.7）和癌症（P = 0.09）死亡率之间没有发现显着的线性关联。此外，马铃薯食用量与癌症死亡风险之间的非线性相关性不显着（P非线性= 0.99）。此外，在三项研究中，有两项研究检查了马铃薯食用量与CVD死亡率之间的关系，但没有发现任何显着的关系。没有证据表明该研究存在出版偏倚。我们未能找到马铃薯食用量与死亡风险之间的显着关联。需要进一步研究以确认此问题。我们未能找到马铃薯食用量与死亡风险之间的显着关联。需要进一步研究以确认此问题。我们未能找到马铃薯食用量与死亡风险之间的显着关联。需要进一步研究以确认此问题。
