Abstract

Abstract: Background and aims: The association of water intake with type 2 diabetes mellitus (T2DM) is still unclear. Therefore, the aim of this systematic review and meta-analysis was to synthesize the knowledge about the relationship between water intake and the risk of T2DM. Methods: We conducted a systematic search in PubMed and Scopus up to June 2018 for observational studies. Risk ratios (RR)s and 95% confidence intervals (95% CI)s were calculated and fixed effects models were used. Results: Overall, 6 studies were included in the meta-analyses. There was an inverse relationship between water intake and risk of T2DM (RR: 0.94; 95% CI: 0.91–0.97, P < 0.001) with low heterogeneity ( I2 = 24%, P = 0.24). Conclusion: Our findings indicated that the intake of water was correlated with reduced risk of type 2 diabetes in women and men. These results support the current recommendations of water intake as an inseparable part of a diet with the lowest risk of diabetes mellitus. Highlights: The relationship between water intake and the risk of type 2 diabetes was studied. There was an inverse relationship between water intake and risk of and type 2 diabetes. Drinking plain water resulted in 6% reduced risk in type 2 diabetes.
