Continuous Observations of Behavioural Risk Factors in Asia (COBRA) — COBRA  

Physical Activity Clinical Trial

Official title:
Continuous Observations of Behavioural Risk Factors in Asia (COBRA)

Clinical Trial Summary

The aim of this study is to advance understanding of behavioural risk factors for cardiovascular disease and type 2 diabetes in Singapore.

Clinical Trial Description

BACKGROUND: Modifiable risk factors for non-communicable diseases, including unhealthy diets and movement behaviours, are influenced by complex and dynamic interactions between people and their social and physical environment. Therefore, understanding patterns and determinants of these risk factors as they occur in real-life is essential to enable the design of precision public health interventions. AIMS: The aims of this study are to (1) examine patterns of dietary and movement behaviours in real-time as people go about their daily lives, (2) examine how interactions with the social and physical environment influence dietary and movement behaviours, and (3) examine how these patterns differ by ethnicity and other socio-demographic characteristics. METHOD: This is an observational study in free-living participants over 10 consecutive days, with a 9-day follow-up 6 months later. 1500 participants will be recruited from a large prospective cohort study. Real-time data capture strategies will be used: an ecological momentary assessment (EMA) app with global positioning system (GPS) enabled to collect location data, accelerometers to measure movement, and wearable sensors to monitor blood glucose levels. Participants receive six EMA prompts per day to capture information on diet and movement behaviours (physical activity, sedentary behaviour, sleep), and related contextual factors. A second wave of EMA prompts and GPS monitoring will occur 6 months later. Data will be integrated and analysed using generalised linear models to examine associations between behavioural risk factors and contextual determinants. ;
