FISH CONSUMPTION AND RISK OF CARDIOVASCULAR DISEASE MORTALITY: A DOSE-RESPONSE META-ANALYSIS
Objective To investigate the association of fish consumption with risk of cardiovascular disease (CVD) mortality.Methods A systematic literature search was performed in PubMed,EMBASE,Web of science,Wanfang and Chinese National Knowledge Infrastructure databases up to September 2016-all the Chinese and English literature on the relationship between fish intake and risk of death from CVD was collected.Adopting random effects model,the pooled RR and 95%CI were selected and calculated.The restricted cubic spline model was applied to assess the dose-response relationship.Results A total of 14 prospective cohort studies with 487 442 participants were included in this meta-analysis.For the highest versus the lowest consumption of fish,the pooled RR was 0.91 (95 % CI =0.85-0.96).The dose-response analysis indicated a nonlinear relationship between fish consumption and CVD mortality (P=0.041).Conclusion High fish consumption may be associated with the reduced risk of cardiovascular disease mortality.
