Diet, alcohol and coronary heart disease in men

Insights
High saturated fat intake correlates with coronary heart disease (CHD) mortality, while alcohol consumption shows a negative correlation. Combining dietary and alcohol data significantly improves CHD prediction models.
Area of Science:
- Cardiovascular epidemiology
- Nutritional science
- Public health
Background:
- Established positive correlation between saturated fat intake and coronary heart disease (CHD) mortality.
- Emerging evidence suggests a negative correlation between alcohol consumption and CHD.
- Simple correlations alone do not fully explain international variations in CHD rates.
Purpose of the Study:
- To investigate the combined impact of dietary factors and alcohol consumption on international CHD mortality.
- To develop a predictive model for CHD incorporating multiple risk factors.
Main Methods:
- Analysis of dietary (saturated fat, polyunsaturated fat) and alcohol consumption data from 18 countries.
- Calculation of simple correlation coefficients between consumption patterns and CHD mortality.
- Application of multiple-regression analysis to assess combined predictive power.
Main Results:
- Significant positive correlation found between saturated fat intake and CHD mortality (r=0.71).
- Significant negative correlation observed for polyunsaturated fat (r=-0.34) and total alcohol consumption (r=-0.58).
- A multiple-regression model integrating dietary and alcohol data achieved a high correlation with CHD (r=0.92).
Conclusions:
- Dietary saturated fat and alcohol consumption are key factors influencing international CHD mortality.
- A comprehensive model incorporating both dietary fat and alcohol provides a stronger prediction of CHD rates.
- Further research into the interplay of diet, alcohol, and cardiovascular health is warranted.
Abstract:
It is well known that there is a significant positive correlation between consumption of saturated fat and cholesterol and international mortality from coronary heart disease (CHD). It is less well appreciated that there is a strong negative correlation between alcohol consumption and CHD, as might be expected from the effect of alcohol on high density lipoprotein levels. Neither of the simple correlations, however, account for CHD in many countries. We examined dietary and alcohol consumption data from 18 countries. The simple correlations with CHD are as follows: saturated fat, r = 0.71; polyunsaturated fat, r = -0.34; total alcohol consumption, r = -0.58. A multiple-regression equation incorporating the dietary and alcohol data, however, yields an r of 0.92.
