Abstract

Objective Type 2 diabetes is a major public health problem. The Dietary Approaches to Stop Hypertension (DASH) eating pattern may contribute to managing risk factors of type 2 diabetes. The objective of this study was to conduct a systematic review and meta-analysis on randomized controlled trials (RCTs) that examine the effects of DASH diet consumption on the indices of glycemic control such as fasting blood glucose (FBG), serum fasting insulin level, and Homeostatic Model Assessment insulin resistance (HOMA-IR).Methods We searched Pubmed, EMBASE, Science direct, ISI web of science, and Google Scholar for RCTs until July 2012. In total we found 20 articles that examine the effect of DASH diet on FBG (n = 9), fasting insulin (n = 7) and HOMA-IR (n = 4) met the inclusion criteria, respectively.Results Meta-analysis showed that the DASH diet can significantly reduce fasting insulin concentration (mean difference -0.15; 95% confidence interval [CI], -0.22 to -0.08; P < 0.001). Subgroup analysis based on the study period showed that the DASH diet could significantly reduce fasting insulin levels when prescribed for more than 16 wk (mean difference -0.16; 95% CI, -0.23 to -0.08; P < 0.001). Meta-analysis could not show a beneficial effect of the DASH diet on FBG (mean difference -0.26; 95% CI, -0.56 to 0.05; P = 0.1), and HOMA-IR (mean difference -0.26; 95% CI, -0.56 to 0.05; P = 0.1).Conclusions The DASH dietary pattern may lead to an improvement in insulin sensitivity independent of weight loss. The DASH diet may play an important role in glycemic control in long- term interventions. Additional prospective studies regarding the association between DASH diet and risks for type 2 diabetes are necessary.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
