ARTICLE HIGHLIGHTS
Research background
The previous systematic reviews showed that an inverse association between coffee consumption and the risk of type 2 diabetes mellitus (T2DM).
Research motivation
While the differences in coffee consumption habits by region could create heterogeneity, further evaluations between coffee consumption and the risk of T2DM in Asian populations are needed.
Research objectives
The aimed to conduct a meta-epidemiological study to evaluate the association between coffee consumption and the risk of T2DM in Asian men and women.
Research methods
After selecting the studies meeting the selection criteria, a fixed-effect model meta-analysis and two-stage fixed-effects dose-response meta-analysis were performed.
Research results
Coffee consumption could decrease the occurrence of T2DM in the Asian population, and drinking a cup of coffee per day reduced the risk of T2DM in the Asian population by approximately 8%.
Research conclusions
This meta-epidemiological study concluded that coffee consumption could prevent the occurrence of T2DM in Asian populations.
Research perspectives
Further studies are needed to investigate the preventive mechanism of coffee using a metabolomics study.
