An interventional study of CoSIE app in Childhood Obesity, sponsored by Azienda USL Reggio Emilia - IRCCS. Completed at 1 site in Italy. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-06-25.
Sponsored by Azienda USL Reggio Emilia - IRCCS · Not applicable, Interventional, and Prevention
The objective of the study is to evaluate the effectiveness of the app in terms of changing lifestyles both related to nutrition and physical activity. The study is also aimed at evaluating the usability and the degree of acceptance of the app among parents.
The primary objective will be assessed in terms of the change in the consumption of sugary drinks and high-calorie food and in terms of time spent in front of a screen.
The secondary objectives are the evaluation of BMI (percentile and z-score) and waist circumference and the evaluation of the usability of the app.
STUDY DESIGN The study is a randomized control trial. Both parents and children are recruited.
When the study is presented to families, few clinical information are collected on the electronic platform designed for enrollment and randomization:
More information about children and parents are collected (through questionnaire).
The families (both treatment and control ) are contacted after 12 month and after 24 months from the recruitment to answer to a questionnaire on lifestyle habits (food and physical activity) of the child and app utilization
During this visit also child weight, height and waist circumference will be collected.
Intervention group The app is explained and installed during the recruitment to the family in the intervention group.
Some families in this group will be selected to take part to the qualitative research.
Control group Every months during the first year of study a newsletter is sent only to the members of the control group.
Childhood obesity is a highly prevalent condition and together with the behaviours associated with it, such as improper diet and physical inactivity, it generates a high burden of disease in adulthood.
In recent years, it is increasing the use of mobile devices in support of health prevention and promotion strategies. In a primary care setting these new technologies offer the opportunity to open a two-way communication channel between parents and institutions and can help by adapting the intervention and framing the message according to the needs of each family.
Since 2010, the Reggio Emilia AUSL has started a research and interventions program aimed at preventing childhood obesity. The program has adopted a multilevel and multi-setting strategy for primary prevention (BMInforma Program).
Since 2017, together with the University of Bologna and the regional company Lepida2000, the Local Health Authority is part of the Co-creation of Service Innovation in Europe project (CoSIE Project), a project funded by the European Union with a Horizon 2020 call coordinated by the University of Turku, Finland. The CoSIE project promotes the co-creation of public services through the involvement of citizens and other interested parties in the definition of objectives and delivery methods.
The project is divided into nine pilot projects and the Italian pilot project, carried out in the province of Reggio Emilia, is part of the AUSL program for the prevention of childhood obesity. The aim of the pilot project is to create a network between the services involved in the prevention and treatment of obesity and, at the same time, it aims to create an app that can help promote a healthy lifestyle. The app was designed and created with a co-creation process.
The objective of the study is to evaluate the effectiveness of the app in terms of changing lifestyles both related to nutrition and physical activity. Furthermore,an aim of the study is to evaluate the usability and the degree of acceptance of the app among parents.
