Biomarkers of Physical Activity/Health in Children and Adolescents (INTEGRActiv)
Identification and Validation of Integrative Biomarkers of Physical Activity Level and Health in Children and Adolescents
Study Overview

Intervention / Treatment
Detailed Description
Physical activity (PA) provides health benefits across the lifespan and improves many established cardiovascular risk factors that have a significant impact on overall mortality. Childhood and adolescence are critical periods for life-time health; processes underlying cardiovascular diseases and obesity generally originate in early ages. However, it is not clear how PA links to different parameters of health.
There is an important need to cover this critical gap and, more specifically, to have biomarkers allowing to relate the degree of PA with effects on health. INTEGRActiv addresses this new scientific and societal challenge by focusing on the identification of integrated markers reflecting both aspects - PA level and health - in children and adolescents, which represent an important target population to address personalized interventions to improve future, life long, metabolic health. Identification of new biomarkers will be achieved by combining measures of PA and cardiorespiratory and muscular fitness with anthropometric measures, cardiovascular risk factors and endocrine markers, cytokines, circulating miRNA, and gene expression profile in blood cells and metabolomics profile in plasma and blood cells.
Following identification in a core cohort and data integration analysis, candidate biomarkers will be further assessed in core cohort subjects after educational intervention and in existing samples from other independent studies. INTEGRActiv encompasses relevant progress beyond the state-of-the-art for a) the definition of potential biomarkers for PA level in childhood and adolescence; b) the provision of relevant mechanistic information for the link between PA and metabolic health in youth subjects; c) the identification of factors such as age, gender, body weight, sleep behavior and puberal status that quantitatively affect biomarker responses; d) the use and development of new tools in biomarker research, including integrative analysis; e) further assessment and first-step validation of promising candidate biomarkers in an intervention study and other independent studies. It is expected that new identified robust biomarkers reflecting PA level and its relation with health will guide nutritional/life-style and clinical advice and public policies related to endorse biomarker- based personalised PA, with a better adherence and response, to promote health and prevent disease risk factors since early stages of life.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Prepubertal group: Educational intervention
An educational intervention to improve physical activity and promote healthy dietary habits will be carried out in prepubertal (8-10 years) volunteers with normal weight (NW), overweight (OW), and obesity (OB).
|
The intervention will consist of recommendations to improve physical activity (PA) and dietary habits.
It is based on the PAIDO Programme (www.programapaido.es),
an outpatient family-based multidisciplinary programme that combines PA, education on nutrition, and behavioural therapy.
It will last 6 months and improvement of metabolic health and body weight loss is expected, particularly in the groups with overweight and obesity.
The dietary intervention will be focused on the promotion of the Mediterranean diet, with follow-up and advice from a dietitian-nutritionist.
Participants will be encouraged in reducing sedentary behaviour (watching television, playing computer games, playing board games).
Performance of aerobic and strength physical exercises will be scheduled, progressively increasing the intensity.
Volunteers and their parents will participate in monthly sessions to follow-up on adherence to the PA and dietary recommendations and give personalized advice.

Experimental: Postpubertal group: Educational intervention
An educational intervention to improve physical activity and promote healthy dietary habits will be carried out in postpubertal (13-15 years) volunteers with normal weight (NW), overweight (OW), and obesity (OB).
