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. We measured weight (kg), height (cm), waist circumference (cm), skinfold thicknesses (bicipital, tricipital, subscapular and suprailiac) and blood pressure. 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 Blood Pressure Education Program Working Group.
Open access to the scientific literature means the removal of barriers (including price barriers) from accessing scholarly work. There are two parallel roads towards open access: Open Access articles and self-archiving. Open Access articles are immediately, freely available on their Web site, a model mostly funded by charges paid by the author (usually through a research grant). The alternative for a researcher is self-archiving (i.e., to publish in a traditional journal, where only subscribers have immediate access, but to make the article available on their personal and/or institutional Web sites (including so-called repositories or archives)), which is a practice allowed by many scholarly journals.
Open Access raises practical and policy questions for scholars, publishers, funders, and policymakers alike, including what the return on investment is when paying an article processing fee to publish in an Open Access articles, or whether investments into institutional repositories should be made and whether self-archiving should be made mandatory, as contemplated by some funders.
