The objective is to analyze the association between the degree of compliance with Mediterranean Diet and blood pressure in 1078 Spanish schoolchildren (514 boys, 564 girls) aged 9 to 16 years. The Waist-to-Height Ratio (WtHR), Body Mass Index (BMI), and the percent body fat (%BF) were calculated.
Subjects were classified as “underweight”, “normal weight”, “overweight” or “obese” according to the International Obesity Task Force (IOTF). Diet quality was assessed by the KIDMED Index and the hypertensive status according to National High BP Education Program Working Group.
A multiple linear regression analysis found that KIDMED index had a negative correlation with systolic and diastolic pressure. Also BMI and WtHR were positively correlated with both blood pressure levels, and % BF was associated only with diastolic BP.
