The current cohort study shows the inconsistent association between potato consumption and the risk of type 2 diabetes mellitus (T2DM). Therefore, we conducted a systematic review and dose-response meta-analysis of published prospective cohort studies to quantitatively estimate this association. We searched PubMed, Embase, MEDLINE, Web of Knowledge, and the Cochrane Library up to September 2019 for all published articles. Seven of the articles reported nine cohort studies with 383,211 participants, with 23,189 T2DM cases that met the inclusion criteria and were included for our analysis. The results of random effects model pooled relative risk (RR) showed an association between potato intake and the risk of T2DM (pooled RR = 1.13, 95% CI: 1.02-1.26, > 0.01). In the subgroup analysis, French fries, long-term follow-up, large sample size, and high-quality studies were associated with an increased T2DM risk. Further, a linear dose-response analysis indicated that 100 g/day increment of total potato (RR = 1.05, 95% CI: 1.02-1.08) and French fries (RR = 1.10, 95% CI: 1.07-1.14) consumption may increase the risk of T2DM by 5% and 10%, respectively. Our meta-analysis showed that potato consumption, especially French fries consumption, was associated with increased T2DM risk.
目前的队列研究表明，土豆摄入量与 2 型糖尿病（T2DM）风险之间的关联并不一致。因此，我们进行了系统评价和剂量-反应荟萃分析，以定量评估这种关联。我们检索了 PubMed、Embase、MEDLINE、Web of Knowledge 和 Cochrane Library 截至 2019 年 9 月发表的所有文章。其中有 7 篇文章报道了 9 项队列研究，共有 383211 名参与者，其中 23189 例 T2DM 病例符合纳入标准，并纳入了我们的分析。随机效应模型汇总的相对风险（RR）结果表明，土豆摄入量与 T2DM 风险之间存在关联（汇总 RR = 1.13，95%CI：1.02-1.26， > 0.01）。在亚组分析中，炸薯条、长期随访、大样本量和高质量的研究与 T2DM 风险增加相关。此外，线性剂量-反应分析表明，每天增加 100 克总土豆（RR = 1.05，95%CI：1.02-1.08）和炸薯条（RR = 1.10，95%CI：1.07-1.14）的摄入量可能分别使 T2DM 风险增加 5%和 10%。我们的荟萃分析表明，土豆的摄入，特别是炸薯条的摄入，与 T2DM 风险的增加有关。
