HealthDay News — Greater adherence to a Mediterranean-style diet is tied to decreased left ventricular (LV) mass, according to results of a study published in The American Journal of Cardiology.
To investigate the correlation between Mediterranean-style diet adherence and LV mass, Hannah Gardener, ScD, of the University of Miami Miller School of Medicine, and colleagues assessed diet and LV mass in 1,937 participants of the Northern Manhattan Study. The participants were aged a mean of 67 years. A diet adherence score (range 0 to 9, with 9 representing maximal adherence) was examined.
An inverse association between the adherence to the Mediterranean diet and LV mass was found. LV mass was 1.98 g lesser for each 1-point greater diet score, after controlling for demographics, behavioral risk factors, diabetes, and blood pressure variables.
For those with scores of 6 to 9, average LV mass was 7.30 g less compared with patients with scores of 0 to 5. When adjusting for body mass index this association weakened, but remained statistically significant.
“Greater adherence to a DT is associated with decreased LV mass, an important risk factor for cardiovascular disease, and this association may be partly mediated by obesity,” concluded the investigators.
