Dietary Patterns and Risk of Stroke in Adults: A Systematic Review and Meta-analysis of Prospective Cohort Studies

BACKGROUND: The effect of whole diet on the development of stroke has recently achieved much interest by various prospective studies, but with inconclusive results. Herein, we carried this meta-analysis to identify the potential associations between different dietary patterns and the risk of stroke by pooling available data from existing studies.

METHODS: PubMed and EBSCO were searched for pertinent articles that identify dietary patterns published from January 1991 to November 2014, with the following keywords: dietary pattern, dietary patterns, food pattern, eating pattern, alcohol drinking, alcohol consumption, and stroke.

RESULTS: A total of 21 studies met the inclusion criteria and were included in this meta-analysis. A decreased risk of stroke was shown for the highest compared with the lowest categories of healthy dietary pattern (odds ratio [OR] = .77; 95% confidence interval [CI] = .63-.93; P < .00001) and light-moderate drinking pattern (OR = .80; 95% CI = .72-.90; P = .0002). There was evidence of the increase in the risk of stroke in the highest compared with heavy alcohol-drinking pattern (OR = 1.25; 95% CI = 1.17-1.33; P < .00001), whereas no significant association with Western-style dietary pattern was observed (OR = 1.05; 95% CI = .82-1.35; P = .70).

CONCLUSIONS: The results of this meta-analysis indicated that some dietary patterns may be associated with the risk of stroke.
