Sex-differences in Mediterranean diet: a key piece to explain sex-related cardiovascular risk in obesity? A cross-sectional study

Abstract

Background

Mediterranean Diet (MD) has many health benefits, particularly in reducing cardiovascular risk (CVR). However, it is still little known if there are any sex differences in following this nutritional pattern and, thus, the potential sex-related repercussions on CVR in obesity. The study aimed to characterize sex-related adherence to MD and its association with CVR factors in subjects with obesity.

Methods

A total of 968 females (33.81 ± 11.06 years; BMI 34.14 ± 7.43 kg/m²) and 680 males (aged 34.77 ± 11.31years; BMI 33.77 ± 8.13 kg/m²) were included in a cross-sectional observational study. Lifestyle habits, anthropometric parameters, high sensitivity C-reactive protein (hs-CRP), and adherence to MD were evaluated.

Results

Females had significantly higher adherence to MD and lower hs-CRP levels than males (p < 0.001). Additionally, females consumed significantly more vegetables, fruits, legumes, fish/seafood, nuts, and sofrito sauce and less quantity of olive oil, butter, cream, margarine, red/processed meats, soda drinks (p = 0.001), red wine, and commercial sweets and confectionery than their counterparts. A PREDIMED score of ≤ 6 was associated with a significantly increased CVR in both sexes.

Conclusions

Females had higher adherence to MD, lower CVR, and different food preferences than males. Although the same PREDIMED threshold has been identified as a spy of CVR, the sex-related preference of individual foods included in the MD could explain the different impact of this nutritional pattern on CVR in both sexes.
