Modified Mediterranean diet score adapted to a southern Mediterranean population and its relation to overweight and obesity risk.

OBJECTIVES

The current study aimed to develop a modified Mediterranean diet (MMD) score adjusted to the southern Mediterranean countries' cultural specificities and to evaluate associations between adherence to this modified score and overweight/obesity risk in Moroccan adults.

DESIGN

Population-based cross-sectional study.

SETTING

Rural and urban areas of the five greatest provinces of Morocco.

PARTICIPANTS

In total, 1516 participants were recruited between September 2009 and February 2017. Dietary assessment was obtained using a validated Moroccan FFQ. We constructed a MMD score focusing on twelve components. The MMD score ranged from 0 (no adherence to the traditional southern Mediterranean diet (MD)) to 12 (maximal adherence) and was categorised as low (scores 0-4), moderate (scores 5-7) and high (scores 8-12).

RESULTS

Among the whole population, 754 (50·5 %) were women and 738 (49·5 %) were men, and the mean age was about 55·60 ± 13·70. In total, 58 % of participants were moderately active. Regarding educational level, 50·7 % were illiterate. The prevalence of overweight and obesity was 43·3 and 8·6 %, respectively. In multivariate analyses, close adherence to MMD (scores 8-12) was associated with reduced overweight/obesity risk (OR 0·61, 95 % CI 0·44, 0·84).

CONCLUSION

The prevalence of overweight and obesity was very high among Moroccan adults. Adherence to the traditional southern MD may help prevent overweight and obesity.
