Abstract
WHELTON and others, Tulane University School of Public Health and Tropical Medicine, New Orleans, Louisiana, USA, have conducted a meta-analysis of observational studies on fish intake and coronary heart disease.
Background
The eating of oily fish has been associated with a lower risk of coronary heart disease in some but not all studies.
Methodology
In this meta-analysis, 19 observational studies were analyzed, of which 14 were cohort studies and 5 case-control studies. Using a random effects model, data from each study were pooled.
Results
Fish consumption versus little or no fish consumption was associated with a relative risk of 0.83 (p < 0.005) for fatal coronary heart disease and a relative risk of 0.86 (p < 0.005) for total coronary heart disease.
Conclusion
The results indicate that eating fish significantly lowers the risk of coronary heart disease and may be an important lifestyle component for heart disease prevention.
