Study of Indoor Air Pollutants and Their Impact in Children's Health and Wellbeing

Disrupting Noxious Synergies of Indoor Air Pollutants and Their Impact in Childhood Health and Wellbeing, Using Advanced Intelligent Multisensing and Green Interventions: an Interventional Study in a Sub-group of Schoolchildren

Sponsor

University Hospital, Montpellier

Enrollment

100 participants

Start Date

Feb 4, 2026

Study Type

INTERVENTIONAL

Conditions

Allergy

Summary

The goal of this study is to identify and assess in real time the impact of the combined action of various types of air and dust pollutants within a classroom on children's health and quality of life, particularly regarding atopic/allergic diseases in children, and on potential exposure to pollutants at home. Participants will answer questionnaires regarding their health and medications, undergo allergy tests, perform non-invasive lung function tests and check blood oxygen levels.

Plain Language Summary

Simplified for easier understanding

This study is examining how indoor air pollutants (such as mold, dust, chemicals from cleaning products, or smoke) affect children's health — particularly conditions like asthma, allergies, and skin problems. It is part of a larger international research project. **You may be eligible if...** - Your child is already enrolled in the SynAir-G observational study - Your child and your family are willing to follow the study procedures - For the "case" group: your child has asthma, wheezing, allergic rhinitis, or atopic dermatitis (eczema) - For the "control" group: your child does not have any of those conditions **You may NOT be eligible if...** - Your child is not part of the SynAir-G study - You as a parent or guardian are unwilling to give written consent Talk to your doctor to see if this trial is right for you.

Interventions

OTHERStandardized questionnaires

Baseline questionnaires for cases and follow-up questionnaires for cases and controls will be completed to collect data on sociodemographic characteristics, health outcomes, potential risk factors, lifestyle, and living environment.

OTHERLung function tests

All participants, including cases and controls, will undergo comprehensive spirometry testing, pulse oximetry assessment, and fractional exhaled nitric oxide (FeNO) measurement.

DIAGNOSTIC_TESTPrick tests

Cases and controls will undergo skin prick testing for common allergens, including house dust mites, cat, dog, Alternaria, cypress, birch, plane tree (Platanus), grass, latex, olive tree, ragweed, and mugwort,...

OTHERBiological samples

Subjects and their parents/guardians will be given the option to provide blood, urine, and nasopharyngeal samples.

DEVICEPortable sensors

Up to 10 subjects ( with their parents/guardians consent) will be given the option to use CANARIN devices, to monitor at the individual level exposures to air pollutants (PM and VOC) and other environmental factors (temperature, humidity, pressure) in and outside school.
