About this study
Official title: BioNortHealth Project: Creation of a Cohort of Adolescents and Young Adults Supported by Digital Biobanks
The goal of this observational longitudinal cohort study is to identify key lifestyle-related predictors of health and disease and to understand how health trajectories develop over time in adolescents and young adults.
The main questions it aims to answer are:
Read more
- How are lifestyle habits associated with health indicators in adolescents and young adults?
- Which individual, social, and environmental factors act as risk or protective determinants of health over time?
- How do lifestyle behaviours and health determinants evolve during critical life transitions, particularly academic transitions?
What causal relationships exist between changes in lifestyle habits and health outcomes, after controlling for potential confounders?
Participants will:
- Provide digital health and lifestyle data through a digital biobank platform;
- Be followed longitudinally with repeated data collection over time;
- Contribute information related to health status, lifestyle behaviours, and individual, social, and environmental determinants.

This variable will be estimated using validated actigraphy algorithms applied to data collected by the ActiGraph wGT3X-BT, reflecting the transition from wakefulness to sleep.
Measured: Baseline, Year 3, Year 5
Wake After Sleep Onset (WASO)
Wake After Sleep Onset (WASO) will be defined as the total amount of time spent awake after sleep onset and before final awakening. This parameter will be derived from periods of wakefulness identified within the sleep interval using accelerometry data from the ActiGraph wGT3X-BT, providing an index of sleep fragmentation.
Measured: Baseline, Year 3, Year 5
Fragmentation Index / Nocturnal Movement
The Fragmentation Index will be used as an indicator of sleep continuity, reflecting the frequency and extent of nocturnal movement and brief awakenings during the sleep period. This variable will be derived from raw accelerometry data recorded by the ActiGraph wGT3X-BT and computed using algorithms implemented in the ActiLife software, depending on the selected scoring method.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The goal of this observational longitudinal cohort study is to identify key lifestyle-related predictors of health and disease and to understand how health trajectories develop over time in adolescents and young adults.
The main questions it aims to answer are:
- How are lifestyle habits associated with health indicators in adolescents and young adults?
- Which individual, social, and environmental factors act as risk or protective determinants of health over time?
- How do lifestyle behaviours and health determinants evolve during critical life transitions, particularly academic transitions?
What causal relationships exist between changes in lifestyle habits and health outcomes, after controlling for potential confounders?
Participants will:
- Provide digital health and lifestyle data through a digital biobank platform;
- Be followed longitudinally with repeated data collection over time;
- Contribute information related to health status, lifestyle behaviours, and individual, social, and environmental determinants.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Nuno B Rocha, PhD (+351 22 206 1000, bionorthealth@ess.ipp.pt), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Food Propensity Questionnaire (time frame: Baseline, Year 2, Year 3, Year 4, Year 5). The study lists 46 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
