Clinical Trial Summary

The goal of this observational study is to reduce an individual's cardiometabolic disease risk by improving the ability to detect cardiometabolic disease risk in young adults through the use of novel technologies that increase access to and examine the utility of, a continuous metabolic syndrome severity score. An additional goal of this study is to understand the barriers to engagement in health-promoting behaviors and beliefs about interventions aimed at mitigating metabolic syndrome risk through a brief online lifestyle intervention. The main question[s] it aims to answer are: - Can a smartphone-based imaging system accurately predict a continuous metabolic syndrome severity score, in addition to other markers of cardiometabolic disease, in young adults? - What is the relationship between autonomic dysfunction and metabolic syndrome severity in a cohort of young adults? - What is the relationship between peripheral vascular dysfunction and metabolic syndrome severity in a cohort of young adults? - What are the associations between metabolic syndrome severity and gait and functional ability in young adults using novel markerless motion capture technology? - What are the attitudes and barriers towards lifestyle interventions targeted to reduce metabolic syndrome severity? - What are the treatment-seeking and willingness to engage behaviors toward a webpage focused on lifestyle interventions to reduce metabolic syndrome severity? Participants will be asked to undergo several assessments across four separate days which are design designed to determine the associations between cardiometabolic health markers and components of: - body composition - cardiovascular function - functional ability - attitudes and behaviors towards health-related interventions
