ClinConnect Summary

This clinical trial, called the Better4All Personalized Intervention Pilot Study, is focused on preventing obesity by using a special program tailored to each person’s lifestyle. The study uses smartwatches and a mobile app to track daily habits like eating, exercise, sleep, and the environment around you (such as how close you are to parks). The goal is to see if this technology and the personalized advice it offers are easy to use and helpful before testing it on a larger scale.

Adults aged 18 to 65 who live in one of the seven participating countries (Cyprus, France, Greece, Poland, Portugal, Spain, or Sweden) may be eligible. Participants should either have a normal weight or be overweight/obese and need to be comfortable using a smartwatch and an Android smartphone app. During the three-week study, participants will wear the smartwatch and use the app to record their daily behaviors. Healthcare providers will also try out the system to help improve it. This pilot study will help the researchers make the program better and easier to use for everyone before it is offered to more people.
