About this study
ACTION Teens is a multinational cross-sectional survey-based study. The study consists of a quantitative online survey to be conducted among three groups of respondents in ten countries worldwide. The respondent population will include Adolescents Living with Obesity (ALwO), Caregivers of ALwO, and HCPs treating adolescents who have obesity.
The goal of this study is to provide insights to drive awareness around the needs of adolescents living with obesity and their caregivers, as well as to identify key areas of misalignment between adolescents, their caregivers and the HCPs involved in obesity treatment and management. ACTION Teens is designed to generate evidence to identify and address these challenges on both a global and local level, extending the insights from the previously conducted ACTION-IO study.
