Mediterranean diet, alcohol-drinking pattern and their combined effect on all-cause mortality
A research team assessed the joint effect of adherence to the MedDiet and alcohol-drinking pattern on all-cause mortality. 20,506 subjects from a prospective cohort of Spanish university graduates, the Seguimiento Universidad de Navarra (SUN) cohort were included in the research. Adherence to the MedDiet was operationalised using four different dietary indexes and then categorised in low or high adherence, according to the median score. Alcohol-drinking pattern was evaluated with the previously defined the Mediterranean Alcohol-Drinking Pattern (characterised by red wine consumption, moderate intake, and wine consumed with meals and without excess), grouped into three categories of adherence (low, moderate and high adherence) and a fourth category for abstainers. During a median follow-up of 12.1 years, there were 460 deaths. No statistically significant supra-multiplicative interaction between the two exposures was found. Low adherence to both the MedDiet and Mediterranean alcohol-drinking pattern was associated with higher all-cause mortality compared to high adherence to both exposures [multivariable-adjusted hazard ratio (HR) = 2.02, 95% confidence interval (CI): 1.33–3.07]. Similar results were found for cancer mortality and cardiovascular mortality. Although the combined effect of the MedDiet and Mediterranean alcohol-drinking pattern was not significantly higher than the product of their individual effects, a low adherence to both the MedDiet and MADP was associated with higher rates of all-cause mortality. The authors comment that this study also shows the usefulness of the dietary pattern approach applied to alcohol intake and of including the drinking pattern as another component of the MedDiet.
