^*Multiple linear regression was used. All models were adjusted for age, sex, educational level, residence, employment status, tobacco smoking and physical activity. DII, dietary inflammatory index; Ref, reference.

^†Metabolic syndrome was defined following the National Cholesterol Education Program Adult Treatment Panel III recommendations, which consider the presence of ≥ 3 of the following components shown in footnotes 3–7.

^‡Hyperglycaemia > 100 mg/dl.

^§Hypertriglyceridaemia > 150 mg/dl.

^||HDL-cholesterol: < 40 mg/dl in males or < 50 mg/dl in females.

^¶Hypertension: systolic > 130 mmHg or diastolic > 85 mmHg.

^**Abdominal obesity > 102 cm for males or > 88 cm for females.
