Food Compass Score predicts incident cardiovascular disease: The ATTICA cohort study (2002-2022).

BACKGROUND: The Food Compass Score (FCS) is a novel nutrient profiling system, which evaluates food and diet quality. The present study aimed to prospectively assess the relationship of FCS with short-term (10 years) and long-term (20 years) cardiovascular disease (CVD) incidence and to explore whether this relationship is modified by long-term adherence to a Mediterranean type diet (MTD). METHODS: Volunteers of the ATTICA cohort study, with complete data for the calculation of FCS and incident CVD were included (n = 759). Development of CVD was determined at 10 and 20 years after baseline. Dietary intake was assessed through a validated food frequency questionnaire. The FCS was calculated for each participant based on the published algorithm. Long-term adherence to a MTD was evaluated through MedDietScore. RESULTS: FCS was inversely associated with CVD incidence (hazard ratio [HR] for 20-year follow-up = 0.97, 95% confidence interval [CI] = 0.95-0.99; HR for 10-year follow-up = 0.98, 95% CI = 0.96-1.01) in the total sample, as well as in those with a high baseline adherence to a MTD (HR for 20-year follow-up = 0.96, 95% CI = 0.93-0.99; HR for 10-year follow-up = 0.98, 95% CI = 0.95-1.02). FCS was also inversely associated with CVD risk in those who went away from the MTD (HR = 0.97, 95% CI = 0.96-0.99). CONCLUSIONS: FCS, a novel tool for assessing overall diet quality, was also found to be useful in identifying potential CVD candidates in a long-term period, even in populations with good background dietary habits, such as those following a MTD.

Mediterranean Diet and Cardiovascular Disease: The Moderating Role of Adequate Sleep-Results from the ATTICA Cohort Study (2002-2022).

The relationship between diet, sleep duration and cardiovascular disease (CVD) has not been well understood. The aim of the present study was to test the potential modifying role of sleep duration in the association between adherence to the Mediterranean-type diet (MD) and CVD risk. The study consisted of n = 313 initially free-of-CVD adults, from the ATTICA cohort study (2002-2022), with available information on sleep habits. Sleep habits were categorized as inadequate and adequate sleep duration (< or ≥7 h/day, respectively). In multi-adjusted analysis, MD adherence was inversely associated with CVD risk [Hazard Ratio-HR per 1/55 in MedDietScore: 0.80, 95% Confidence Interval-CI: 0.65, 0.98]. A significant interaction between sleep duration and MedDietScore was observed (p < 0.001). In subgroup analysis, the protective association between MD adherence and CVD risk was found only in participants who slept adequately, i.e., >7 h/day [HR:0.80, 95%CI: 0.65, 0.98]. Those who had a high adherence to the MD along with adequate sleep habits, had a 70% reduced 20-year CVD risk [HR:0.30, 95%CI: 0.11, 0.80], compared to those who had a low MD adherence and inadequate sleep habits. Sleep duration should be a part of an individual's lifestyle, together with dietary and other habits, to effectively evaluate CVD risk for future events.
