Objective: The purpose of this study was to examine the relationship between alcohol consumption and selected heart diseases [Coronary Heart Disease (CHD), Myocardial Infarction (MI) and Atrial Fibrillation (AF)]. Methods: Analysis was performed on 5301 individuals in the JHS baseline examination 2000 -2004 to identify relationships between alcohol consumption and selected heart disease in African Americans in the Jackson Heart Study. Binary logistic regression modelling was used to compute the odds ratios for each type of heart disease outcome under investigation. Results: Participants who drank < 1 drink per week got CHD 0.645 times less often than those who drank > 14 drinks per week. Participants who drank < 1 drink per week got MI 0.605 times less often than those who drank > 14 drinks per week. Those who drank 1-7 drinks per week got MI 0.966 times less often than those who drank >14 drinks per week. Those who drank 8-14 drinks per week got MI 0.346 times less often than those who drank > 14 drinks per week. Conclusions: The odds of having CHD are reduced with the reduction in drinking. Participants who drink less than 1 drink of alcohol per week have a significantly reduced risk of having two of the outcome measures of interest (CHD and MI). AF was eliminated from the analysis because of the few numbers of African Americans in the Jackson Heart Study who were diagnosed with the disease.
