Moderate drinking and cardiovascular disease

The adverse consequences of heavy alcohol use are well known. However, recent media reports of a possible cardiovascular benefit associated with moderate drinking have revived public interest in the use of alcohol for "medicinal purposes." Knowledge development regarding guidelines for moderate alcohol use has lagged behind public interest in the possible health benefits of moderate alcohol use. At this time, evidence-based primary health promotion interventions related to the risks and benefits of moderate alcohol use are lacking in the health care literature. This chapter reviews 22 reports describing the relationship between moderate drinking and cardiovascular disease. The reports are classified by the level of evidence and critiqued on seven aspects of method. Conclusions related to the strength of the evidence that moderate drinking is a useful primary health promotion intervention are presented.
