General Page PASOS Study

What is PASOS?

Gasol Foundation’s overall mission is to prevent childhood obesity through the promotion of healthy habits. In order to accomplish this, we constantly conduct research and administer studies and initiatives to attain more knowledge regarding the causes and consequences of this epidemic. Having a better understanding of childhood obesity allows us to thoroughly design and implement effective interventions. One of these interventions is PASOS (Physical Activity, Sedentarism and Obesity in Spanish Youth). PASOS is a Gasol Foundation pioneered study utilized to evaluate the physical activity and lifestyles of Spanish children and adolescents from ages 8 to 16 years old.

PASOS is based on the methodology jointly designed by Gasol Foundation and the Hospital del Mar Institute for Medical Research (IMIM). We are also in collaboration with 14 different research centers responsible for managing the field work for this study.

What makes this study relevant?

PASOS has the support of the Ministry of Education and Vocational Training, the Ministry of Health, Consumption and Social Welfare through AESAN (Spanish Agency, Food Safety and Nutrition), the High Commissioner against Child Poverty, the Superior Council of Sports, the General College of Professional Associations of Physical Education and Sports, and the 17 Ministries of Education and/or Health.

Collaborations with organizations and institutions such as these are significant for the PASOS Study for numerous reasons. They help produce efficient and objective data regarding the physical activity levels of children and adolescents to be analyzed; therefore assisting with getting to the root of childhood obesity. Studies such as PASOS proves to be the necessary first steps with preventative measures for the childhood obesity epidemic.  

The participating children:

The representative study of the prevalence of physical activity in Spain will assess:

  • A total of 4,508 children and adolescents ages 8 to 16 from 122 locations selected at random, guaranteeing proportionality of the 17 Autonomous Communities.
  •  Rural, semi-urban and urban areas are among those localities represented.
  • In each area, a Primary and Secondary school have been selected at random.
  • Within each Primary school, grades 3-6 (8 to 12 years old) were selected, and within each Secondary school, grades 1-4 (12 to 16 years old) were selected.


The methodology:

The PASOS methodology combines the collection of anthropometric data of minors and validated questionnaires to be answered by the students through an online application at their respective school. Families will also complete questionnaires pertaining to educational level, occupation and lifestyle.

In addition to questionnaires, 10% of the participants will wear an accelerometer for a total of 9 days. This particular device is similar to a watch in that it is worn on the wrist; however, it will monitor the intensity of exercise, the pattern of physical activity, and the quality of sleep and rest throughout the day.
